+11:43 < horms> good question +11:43 < horms> they are using multiplatform (i believe) +11:43 < horms> and they only care about gen2 +11:43 < horms> so it seems likely +11:43 < horms> but i don't know for sure +11:44 < geertu> renesas-backports/bsp/v3.10.31-ltsi/rcar-gen2-1.9.5:drivers/tty/serial/sh-sci.c still has +11:44 < horms> my feeling about the relationship between this work and the bsp is +11:44 < geertu> struct shdma_desc *sh_desc = container_of(desc, +11:44 < geertu> struct shdma_desc, async_tx); +11:44 < horms> that they have been doing some work to try to stablalise sh-sci +11:44 < geertu> Now, you can still do the container_of() on an rcar-dmac dma_desc object, and get bogus results :-) +11:45 < horms> and i see they have some fixes in the latest v1.9.5 bsp +11:45 < geertu> So I don't think they use rcar-dmac. +11:45 < horms> now, if we can provide them a nice set of fixes to solve their problems then that would be great +11:45 < wsa_> horms: they seem to do, there is even a patch for it in the BSP (which is already upstream, too) +11:45 < horms> but if its invasive, touching all sorts of code, then its not really appropriate for the gen2 bsp +11:46 < shimoda> they use rcar-dmac for audio and some customers uses it for sdhi/mmc +11:46 < shimoda> they = BSP team +11:46 < geertu> #define r8a7791_register_sys_dmac(id) \ +11:46 < geertu> platform_device_register_resndata( \ +11:46 < geertu> &platform_bus, "sh-dma-engine", 2 + id, \ +11:46 < geertu> &r8a7791_sys_dmac_resources[id * 3], id * 1 + 3, \ +11:46 < geertu> &r8a7791_sys_dmac_platform_data, \ +11:46 < geertu> sizeof(r8a7791_sys_dmac_platform_data)) +11:47 < geertu> So they use shdmac with hardcoded chabnnels in board code +11:47 < horms> with multiplatform boots?

+11:49 < horms> i guess it might be either +11:49 < wsa_> if it was a feature, then the bugfix would be to keep on hacking on shdma +11:50 < wsa_> which is not what we really want being the upstram focused team, or? +11:50 < wsa_> (I might be wrong, but I recall Laurent not being very happy with shdma) +11:50 < horms> well, i think that this is one area where there has been some divergence between upstream and the BSP +11:50 < horms> and in my opinion that is not ideal +11:51 < horms> but i wonder what the best way forwards is +11:51 < geertu> r8a7791.dtsi has no "dmas" properties, except in the rcar_sound node +11:51 < horms> i beliwve we have trouble in both mainline and bsp +11:51 < geertu> yes +11:51 < horms> and obviously we wish to fix the former properly +11:51 < geertu> sh-sci needs more care. +11:52 < horms> and ideally take that to the bsp, but i think the devil is in the details +11:52 < horms> regarding how risky the bsp changes might be in terms of stability +11:52 < horms> an unfortunate side effect of this situation is that +11:52 < wsa_> if we would be able to fix it upstream by largely modifying the serial driver only, my hope would be that we could then convince the BSP team to switch over? +11:52 < geertu> the SCIF DNA code is still so complex that there are no obvious deficiencies (I prefer: so simple that there are obviously no deficiencies) +11:52 < horms> its not entirely obvious when a fix for mainline or the BSP is applicable to the other +11:53 < wsa_> horms: true +11:53 < wsa_> there might be side effects +11:53 < geertu> The BSP has several fixes for race conditions, but I don't think they fix the root cause. +11:54 < horms> that would not surprise me +11:54 < geertu> (The same is true for my last RFC series, though) +11:54 < wsa_> but if those side effects come from bugs, then fixing them obviously will change behaviour of the driver +11:54 < horms> they could be positive behavoural changes :^) +11:55 < wsa_> so far, geert's series is completely self contained to the scif driver +11:55 < geertu> Most changes don't look like real behavior changes. Just fixes for rcae conditions. +11:56 < geertu> wsa_: yes +11:56 < shimoda> by the way, I tested geert-san's scif-dma-v2 patch set last week +11:56 < shimoda> and I sent some patches to the ML :) +11:56 < geertu> Thanks for testing, and for the patches. +11:57 < geertu> Which SCI variant(s) did you test? +11:57 < shimoda> i tested on Lager (SCIFA) and koelsch (SCIF) +11:58 < geertu> Good, thanks! +11:58 < horms> ok, i guess we could look at providing some fixes to the bsp team +11:58 < wsa_> my feeling is that it would be worthwhile fixing the remaining issues until we understand what was going wrong and then "sell" our fixes to the BSP team +11:58 < horms> if so i'd like some co-ordination between your changes (and mainine in general) and what is in BSP 1.9.5 +11:58 < geertu> I think it's too early for that +11:59 < horms> i guess you and i could co-ordinate that when the timing is right +11:59 < geertu> Yes, I want to fix the remaining issues first +11:59 < horms> ok, no problem regarding waiting +11:59 < geertu> Ater that I can created a "nicer" series. +11:59 < horms> could you take a look at the new bsp (i pushed it on Saturday) on the off chance any of the scif patches there are of use to you +11:59 < geertu> The current one has too many fixes here, fixes there, ... some of them may not be needed inthe end +11:59 < wsa_> that would hopefully also reduce the gap between BSP & mainline +12:00 < horms> i think you only need to look back as far as v1.9.4 as kaneko-san has already fed the older ones to the ml +12:00 < geertu> I already had a quick look, and none of them looked that exciting +12:00 < horms> thanks +12:00 < horms> that was my expectation +12:00 < horms> I will tell Kaneko-san not to bother posting them to the ml +12:02 < wsa_> ok +12:02 < wsa_> so, geert will push out a nicer series +12:02 < geertu> horms: Thanks, sometimes I'm afraid Greg would apply them ;-) +12:02 < horms> haha +12:02 < wsa_> that can happen +12:02 < wsa_> :) +12:03 < horms> as a precaution i already told him not to post them unless he hears otherwise from me :^) +12:03 < wsa_> and hopefully after the new series, we know a bit more how to deal with the issues +12:04 < horms> sounds reasonable to me +12:04 < wsa_> and then we can have a look what would be best for BSP +12:04 < horms> yes, that can come last +12:04 < horms> imho +12:05 < geertu> I hope scif work will become a bit easier now it's at least working a bit +12:05 < horms> hopefully... +12:05 < geertu> Before it was really frustrating, as any small failure somewhere would lead to one out of many possible crashes due to race conditions +12:05 < horms> ouch +12:05 < geertu> On every retry, I had a different crash ;-) +12:06 < wsa_> yes, working on old serial drivers always deserves a "braveness medal" +12:06 < geertu> I'm wondering how SCIF DMA ever worked. I guess SMP=n helped a lot... +12:07 < wsa_> ok, so much about scif? +12:07 < geertu> Does SCIF DMA work on e.g. Ecovec? +12:07 < horms> i may have one if you really want to find out +12:08 < shimoda> geert-san: I don't know +12:08 < geertu> we never wired up scif dma on e.g. armadillo and kzm9g legacy +12:09 < geertu> wsa_ scif EOF +12:09 < wsa_> :) +12:10 < wsa_> so 3) task list +12:10 < wsa_> I sent it around by mail +12:10 < wsa_> I guess you would have replied if you really missed an item there +12:10 < geertu> Sorry, one more SCIF DMA thing +12:10 < wsa_> ok +12:11 < geertu> The people from Visteon contacted me, as they're interested in it for their product. +12:11 < geertu> For a 4 Mbps link to Bluetooth on SCIFA +12:12 < geertu> Just wanted to let you know... +12:12 < wsa_> set them up for testing ;) +12:13 < wsa_> ok, other comments regarding the io group todo list? +12:13 < geertu> the list looks fine to me +12:14 < morimoto> Sorry, is this "todo list" this ? https://osdr.renesas.com/projects/linux-kernel-development/wiki/Io-todo-list +12:14 < wsa_> yes +12:16 < wsa_> so, when looking for further tasks to keep an eye on, I tried to scan through the BSP +12:16 < wsa_> I concentrated on I2C and MMC for starters +12:17 < wsa_> Conclusion: most patches would already need some investigation to simply understand the problem :) +12:18 < wsa_> and in most cases it is very difficult because there is not enough information to reproduce the issue +12:18 < wsa_> so while "scanning the BSP" sounds good in general +12:18 < wsa_> I am afraid we won't have the bandwidth to do it in general +12:19 < horms> i can get the BSP scanned if you like +12:19 < horms> but my feeling is that its already been scanned up until v1.9.4 (and v1.9.5 but not posted yet) +12:21 < horms> of course you are also welcome to look over it as much as you like +12:22 < wsa_> who scans it? +12:22 < wsa_> kaneko-san? +12:22 < horms> Kaneko-san and I +12:22 < wsa_> ok +12:23 < horms> To be honest I think we got all the fat last year +12:23 < wsa_> I wondered about some MMC related patches +12:24 < wsa_> but my suggestion was anyhow: we bring it to this table here +12:24 < horms> anything in particular +12:24 < horms> i recall some relating to timeouts +12:24 < horms> ok +12:25 < wsa_> if there is something easy, we just pick it +12:25 < horms> as i mentioned earlier the BSP is sort of frozen now +12:25 < wsa_> if there is something "interesting", we can discuss it here or by mail +12:25 < horms> so the reate of patches being added has dropped of significantly since... i guess the begninnging of the year +12:25 < wsa_> ok +12:25 < horms> so there isn't such a large crop of changes to pick from +12:25 < wsa_> "bugfix only" mode? +12:26 < horms> something like that +12:26 < horms> i'm not sure of their exact criteria +12:26 < horms> but its mostly if not exclusively bug fixes from my observations +12:27 < horms> there are a few changes waiting feedback from the BSP team +12:27 < horms> i can try chasing them up +12:27 < horms> which may yeild a few more fixes for mainline +12:27 < wsa_> do you know if there will be another "major version" somewhen or is that "the" BSP foreverß +12:27 < wsa_> ? +12:27 < horms> of course for gen3, yes +12:28 < horms> and probably that will support gen2 in some way (perhaps not officually, but it should boot the boards) +12:28 < wsa_> i understand +12:28 < horms> but for gen2 bsp, i believe the plan is no more major updates +12:28 < horms> actually, i think the plan was no more updates at all: but then some bugs turned up... +12:29 < wsa_> damn software ;) +12:29 < horms> yeah, its like that sometimes +12:31 < wsa_> okay, I think we are done with the planned topics +12:31 < wsa_> anything else which needs to be said now?

PFC +12:29 #periperi: < geertu> GPIO: Looks identical to Gen2 +12:29 #periperi: < geertu> PFC: New driver support (at least the pin/groups/function tables) +12:29 #periperi: < dammsan> geertu: sure, needs DT compat string changes nevertheless +12:29 #periperi: < geertu> (quoting from email "Gen3 work") +12:29 #periperi: < geertu> dammsan: of course +12:30 #periperi: < dammsan> so ulrich posted PFC earlier? +12:31 #periperi: < geertu> no, gpio +12:31 #periperi: < uli___> gpio has been picked up +12:31 #periperi: < geertu> Tasks "gpio,v4.2,Add r8a7795 support" not added +12:32 #periperi: < geertu> Task "irqc,v4.2,Add r8a7795 support" added +12:32 #periperi: < dammsan> ok, thanks for the clarification =) +12:32 #periperi: < geertu> Task "pfc,v4.2,Add r8a7795 support" added +12:32 #periperi: < dammsan> thanks! +12:32 #periperi: < geertu> (v4.2 is due to the internal target date) +12:33 #periperi: < dammsan> geertu: i don't understand the internal target i'm afraid +12:33 #periperi: < dammsan> i thought we tracked when we thought it would be merged upstream +12:33 #periperi: < geertu> "11th" and "18th"? +12:33 #periperi: < geertu> v4.4 +12:33 #periperi: < geertu> updated +12:33 #periperi: < dammsan> thanks +12:34 #periperi: < geertu> I think "Topic 6. SoC Bus topology in DT" is related? +12:34 #periperi: < dammsan> those dates are the upcoming snapshot dates +12:34 #periperi: < geertu> and can be handled together in the last -4 minutes? +12:34 #periperi: < dammsan> i think so, but will take forever i think? +12:34 #periperi: < dammsan> geertu and horms: i asked morimoto-san to fix up some CPG related bits in the Gen3 series and resent V4 +12:35 #periperi: < dammsan> this without dealing with the topology +12:35 #periperi: < horms> so there will be a v5 soon? +12:35 #periperi: < pinchartl> speaking of bus topology, I haven't seen a block diagram that shows the bus topology in the Gen3 datasheet. have I just missed it ? +12:35 #periperi: < dammsan> i doubt we can reach some concensus soon on the topology +12:36 #periperi: < dammsan> if you can tie in the CCI, GIC and CPU clusters with the rest of the topology let me know +12:36 #periperi: < geertu> pinchartl: You need acid and an electron microscope +12:36 #periperi: < dammsan> especially with not so much documentation +12:36 #periperi: < dammsan> i think we need to deal with it bus-by-bus somehow +12:36 #periperi: < pinchartl> I have a bottle of vinegar and a couple of lemons in my fridge. will it do ? +12:36 #periperi: < pinchartl> I think we can start with just one bus, that should be enough +12:37 #periperi: < pinchartl> ideally it should be an AMBA bus +12:37 #periperi: < dammsan> but blocking the series on it seems a bit slow moving, no? +12:37 #periperi: < geertu> indeed +12:37 #periperi: < geertu> just continue +12:37 #periperi: < dammsan> is there any reason why we can't deal with that incrementally? +12:37 #periperi: < shimoda> pinchartl: section 5 AXI-bus is mentioned some diagram +12:38 #periperi: < dammsan> pinchartl: in the end it seems to boil down to trying to describe a non-tree topology as a tree +12:39 #periperi: < shimoda> oops, section 15, not 5 +12:39 #periperi: < pinchartl> some diagrams mention AXI4, others mention APB +12:39 #periperi: < pinchartl> I expect the real bus topology to be quite complex +12:39 #periperi: < dammsan> how about we fix Gen2 first? =) +12:39 #periperi: < pinchartl> and I don't think we really need to describe it fully in DT +12:39 #periperi: < dammsan> at least we have a some chance due to half-stable documentation +12:40 #periperi: < dammsan> as opposed to gen3 +12:40 #periperi: < pinchartl> I'd be fine with just a single bus +12:40 #periperi: < geertu> dammsan And make it not backwards-compatible with the bsp? +12:40 #periperi: < dammsan> geertu: do you mean on a source code level? +12:41 #periperi: < dammsan> geertu: the DT ABI is unaffected, no? +12:41 #periperi: < pinchartl> it would be great if it could be an "arm,amba-bus" but that will require changes to drivers I believe +12:41 #periperi: < dammsan> pinchartl: why don't we begin with a single bus for now then +12:41 #periperi: < pinchartl> dammsan: yes, a single bus is fine +12:41 #periperi: < dammsan> like today? +12:41 #periperi: < pinchartl> what bothered me was the nodes directly under the DT root node +12:42 #periperi: < dammsan> is that different compared to Gen2? +12:42 #periperi: < pinchartl> if we group them in a simple-bus that should be fine +12:42 #periperi: < pinchartl> gen2 has everything at the root +12:42 #periperi: < dammsan> morimoto: did you get that? +12:42 #periperi: < pinchartl> I'd like to avoid repeating that mistake +12:42 #periperi: < pinchartl> it should be very easy to fix +12:42 #periperi: < dammsan> what makes it difficult to move? +12:43 #periperi: < pinchartl> just create a node compatible with simple-bux +12:43 #periperi: < pinchartl> move all memory-mapped IPs there +12:43 #periperi: < pinchartl> and that's it +12:43 #periperi: < dammsan> sure +12:43 #periperi: < geertu> s/simple-bux/simple-bus/ +12:43 #periperi: < pinchartl> simple-bug :-) +12:43 #periperi: < dammsan> but that should be doable for gen2 as well without any odd side effects, no? +12:43 #periperi: < pinchartl> yes it should be doable +12:43 #periperi: < dammsan> you speak bruxells lingo =) +12:44 #periperi: < pinchartl> :-) +12:44 #periperi: < pinchartl> moving to an amba bus would be correct, bus also more complex +12:44 #periperi: < dammsan> sure, but we better be sure what we want at that point +12:44 #periperi: < pinchartl> so let's start with simple bus now +12:45 #periperi: < dammsan> geertu: can we add a task to add simple-bux for Gen3 =) +12:45 #periperi: < geertu> agreed +12:46 #periperi: < geertu> Added "r8a7795,v4.4,Group on-SoC devices under a simple-bus node on r8a7795" +12:46 #periperi: < dammsan> wondeful, thanks! +12:47 #periperi: < geertu> Finished? +12:47 #periperi: < geertu> I mean "any other things to discuss?" :-) +12:47 #periperi: < dammsan> i'm ok for overall stuff, but if people have time left then do we need to bang our head against the topic-branch somehow? +12:47 #periperi: < dammsan> what was the conclusion there again? +12:48 #periperi: < geertu> renesas-drivers will contain the "unstable" stuff, too. +12:48 #periperi: < geertu> But Laurent will remove the hacks for next week's release +12:49 #periperi: < dammsan> as for this week, what will happen? +12:49 #periperi: < geertu> I will create a new unified release using current drm/du/vsp1-kms +12:49 #periperi: < geertu> (after lunch) +12:49 #periperi: < pinchartl> if I remove the hacks (I2C hack and #include of the panel .dtsi), Renesas will need to add them for testing. are they aware of that ? +12:49 #periperi: < dammsan> i think we can manage on this side +12:50 #periperi: < dammsan> especially if you have a local topic branch with that stuff somewhere =) +12:50 #periperi: < dammsan> i mean not local, but separate +12:50 #periperi: < dammsan> we will manage regardless +12:50 #periperi: < dammsan> but it would be nice to see those things somewhere +12:51 #periperi: < dammsan> geertu: sounds good about the release after lunch! thank you! +12:52 #periperi: < dammsan> pinchartl: if you prefer not to publish the hacks separately then thats fine too +12:52 #periperi: < pinchartl> I can push two branches, that's fine +12:52 #periperi: < dammsan> thanks, that's great! +12:53 #periperi: < dammsan> can you drop me an mail once you've gone over to two-branch mode? +12:53 #periperi: < dammsan> i'll inform people +12:54 #periperi: < dammsan> also +12:54 #periperi: < horms> dammsan: can we come back to m1, either here or privately? I'd like to clarify some things. +12:54 #periperi: < dammsan> once we get real gen3 hardware working in the remote access i'll notify the periperi mailing list +12:55 #periperi: < dammsan> horms: sure! +12:55 #periperi: < dammsan> any time +12:55 #periperi: < horms> how about now? :) +12:55 #periperi: < dammsan> sure! =) +12:55 #periperi: < horms> great +12:55 #periperi: < geertu> I'm out for lunch. Bye! +12:55 #periperi: < horms> so i think we almost agreed to remove legacy +12:55 #periperi: < dammsan> geertu: thanks +12:55 #periperi: < dammsan> bon apetit +12:56 #periperi: < horms> but i'm unsure what you want to happen to reference in the short term +12:56 #periperi: < horms> geertu: enjoy +12:56 #periperi: < dammsan> ok i see +12:56 #periperi: < dammsan> i may misunderstand things +12:56 #periperi: < horms> from my pov it should go too +12:56 #periperi: < horms> i.e. be deleted +12:56 #periperi: < dammsan> but the only thing i see at this point is a lot of blocking and not so many patches +12:56 #periperi: < horms> right, that we need to change +12:57 #periperi: < dammsan> i mean, i can do it myself but then what is the point of all this? +12:58 #periperi: < horms> i think i have a clear picture now +12:58 #periperi: < horms> i'll work with uli___ to move things forwards +12:58 #periperi: < dammsan> so is it possible to move forward with the conversion? +12:58 #periperi: < dammsan> i mean, you guys saw my Bock-W patches +12:58 #periperi: < dammsan> i mean Marzen +12:58 #periperi: < dammsan> brain fart +12:58 #periperi: < uli___> since we have come to the conclusion that missing features are not that important, we can go ahead, i guess +12:59 #periperi: < horms> uli___: agreed +12:59 #periperi: < dammsan> auli___: sure that's one important thing +12:59 #periperi: < dammsan> but from my side it looks like you can move forward more without blocking too... +12:59 #periperi: < dammsan> why can't you merge the board DTS files for instance? +12:59 #periperi: < dammsan> is it lack of focus or time +13:00 #periperi: < dammsan> or a technical reason to block it? +13:00 #periperi: < uli___> no, it's just that there is nothing to merge. everything worth keeping is in the other file already. +13:00 #periperi: < uli___> the difference is only in c code +13:00 #periperi: < horms> ok, so we can remove one of the dt files? +13:00 #periperi: < dammsan> so why do we still have two files? +13:01 #periperi: < uli___> because reference needs it. +13:01 #periperi: < dammsan> this portion i don't understand. =) +13:01 #periperi: < dammsan> why can't a single file work? +13:01 #periperi: < dammsan> it did for all other platforms +13:01 #periperi: < dammsan> during transition +13:02 #periperi: < uli___> what for? let's just dump reference altogether. +13:02 #periperi: < dammsan> i realize you have that FPGA thing +13:02 #periperi: < dammsan> uli: but that's wha you are doing if you are merging the DTS files into a single one +13:03 #periperi: < uli___> well, there are a few other things that need to be touched up, but i didn't do this because i considered the missing features to be blockers +13:03 #periperi: < dammsan> everytime i look at the xxx-reference file in arch/arm/boot/dts i wonder why we still have two files for bock-w +13:03 #periperi: < dammsan> ok +13:03 #periperi: < dammsan> but i think we discussed this before, and i pointed out that you can move forward regardless +13:04 #periperi: < dammsan> but anyway +13:04 #periperi: < dammsan> so would it be possible for you to work with simon and finalize the Bock-W bits? +13:05 #periperi: < uli___> sure thing, i have all the patches here. only need to reorder them to "dump first, add features later" +13:05 #periperi: < horms> excellent +13:05 #periperi: < dammsan> uli___: but merging the DTS does not result in any dumping, does it? +13:05 #periperi: < horms> the begining of a merge cycle is an excellent time for remving code. and that means now because i've already started taking patches for v4.4 +13:06 #periperi: < dammsan> uli___: but i understand you mean removing legacy before having equivalent feature support in multiplatform, right? +13:06 #periperi: < uli___> legacy and reference +13:07 #periperi: < uli___> i'd start with reference, it's smaller. but that's just a matter of taste, i guess +13:07 #periperi: < dammsan> horms: so which order do you want stuff? +13:07 #periperi: < dammsan> i probably did the wrong order with the r8a7779 and marzen bits +13:07 #periperi: < dammsan> i did cleanup of -reference first +13:07 #periperi: < dammsan> followed by a legacy removal +13:07 #periperi: < uli___> that's what i thought to do as well +13:08 #periperi: < dammsan> uli___: so i thought you could do a similar series for the -reference cleanup +13:08 #periperi: < dammsan> but without causing any degradation of the multiplatform feature support +13:08 #periperi: < dammsan> (this is the bit i don't understand why it has not happened, but never mind) +13:09 #periperi: < horms> i think that makes sense +13:09 #periperi: < uli___> yes +13:09 #periperi: < horms> its not ideal from a merge pov, but we don't want multiplatform to go backwards +13:10 #periperi: < horms> so i think it is the way to go +13:11 #periperi: < horms> uli___: can you make it so? +13:11 #periperi: < uli___> can do. +13:12 #periperi: < horms> excellent +13:12 #periperi: < horms> please let me know if you hit any snags +13:12 #periperi: < dammsan> uli___: do you have a local board? +13:12 #periperi: < dammsan> (bock-w i mean) +13:12 #periperi: < uli___> nope, i'm using yours. but for removal, that should not be strictly necessary. :) +13:13 #periperi: < dammsan> ok, will remember that you are still using that! +13:13 #periperi: < horms> well, multiplatform will still need to be tested +13:13 #periperi: < horms> btw, i am also using that board +13:13 #periperi: < dammsan> sure +13:13 #periperi: < horms> lets try not to step on each others toes :) +13:13 #periperi: < uli___> unlikely, given the time zone difference, i'd say :) +13:14 #periperi: < horms> yes, agreed +13:14 #periperi: < dammsan> so will you fix it up until next meeting? +13:14 #periperi: < dammsan> i fixed up r8a7779 and the IPMMU prototype last time +13:15 #periperi: < uli___> which is when, btw? +13:15 #periperi: < dammsan> i suppose geert will announce that +13:15 #periperi: < dammsan> my guess would be 2 weeks +13:15 #periperi: < horms> that is my guess too +13:15 #periperi: < uli___> sure +13:16 #periperi: < dammsan> great - that means in 2 weeks i can look forward to no more legacy! +13:16 #periperi: < uli___> whatever makes you happy ;) +13:17 #periperi: < dammsan> reduced whining from ARM-SoC is always a good thing +13:17 #periperi: < dammsan> and reduced whining from me must be nice too =) +13:18 #periperi: < uli___> i'm not going to comment :) +13:18 #periperi: < dammsan> hahah +13:18 #periperi: < uli___> but i will go and have lunch now +13:18 #periperi: < dammsan> sure, have a nice one +13:18 #periperi: < horms> yes +13:18 #periperi: < horms> lets close this for now +13:18 #periperi: < horms> i'm looking forward to seeing some patches +13:19 #periperi: < dammsan> horms: lets continue the remote access discussion tomorrow or friday +13:19 #periperi: < horms> dammsan: i'll be coming and going tomorrow +13:19 #periperi: < horms> friday is probably better for me +13:19 #periperi: < dammsan> sure no worries +13:19 #periperi: < dammsan> have a nice evening and a pleasant tomorrow then =) +13:20 #periperi: < dammsan> see ya later +13:20 #periperi: < horms> thanks you too +13:20 #periperi: < uli___> good night +13:20 #periperi: < dammsan> bye! diff --git a/wiki/Chat_log/20150819-core-chatlog b/wiki/Chat_log/20150819-core-chatlog new file mode 100644 index 0000000..a0273c5 --- /dev/null +++ b/wiki/Chat_log/20150819-core-chatlog @@ -0,0 +1,250 @@ +11:03 #periperi: < geertu> Two more missing?

I can try I2C, but I don't try IIC +11:25 < horms> care -> please look after it +11:25 < wsa_> by the way, does magnus have a "new board" or an "old broken board" in his lab? +11:26 < morimoto> His one is OK board +11:26 < morimoto> but he is using old uboot +11:26 < wsa_> good +11:26 < morimoto> Ah, but 1 note. +11:26 < wsa_> morimoto: do you have a patch for adding all i2c to the r8a7795 dtsi or shall I make one? +11:27 < morimoto> His one has 16.000Mhz as extal clock. +11:27 < morimoto> new board has 16.666HMhz +11:27 < morimoto> First plan was 33.333MHz, but... +11:28 < morimoto> wsa_: I have it, I can send it in v8 +11:28 < wsa_> ok +11:28 < morimoto> wsa_: it is including PFC / MSTP too +11:28 < wsa_> great +11:28 < geertu> Before someone starts writing the SCIF/HSCIF dtsi patch, I have it +11:29 < morimoto> Mine has only SCIF2, can I update it to your one? or do you send it as incremental patch ? +11:29 < morimoto> in v8 +11:29 < geertu> I will send an incremental patch +11:29 < wsa_> is there some schedule when to use magnus gen3 board? +11:29 < morimoto> OK +11:30 < wsa_> i assume core group needs it a lot? +11:30 < wsa_> or first come first serve? :) +11:30 < geertu> It's mutex is kept on #periperi +11:30 < geertu> Currently I have it ;-) +11:30 < wsa_> ok +11:31 < wsa_> anything else related to gen3? +11:32 < horms> yes +11:32 < horms> the bsp team have an etheravb patchset, which i now also have +11:33 < horms> it depends on gpio which ulrich is handling; there were patches for that too which he now has +11:33 < horms> i plan to test the patchset in the near future +11:33 < horms> a blocking item is that it has some non-trivial driver changes that we would like to check for regresssions on 32bit +11:33 < horms> which requires testing +11:33 < wsa_> i see +11:33 < horms> i believe shimoda-san will handle that when he has time +11:34 < wsa_> are the changes needed for basic support or for the extended feature set? +11:34 < horms> in the short term we may be able to get 100Mbit working and on a ML +11:34 < shimoda> horms: yes, i will try that on alt + expantion board +11:34 < horms> there is some special sauce required for futher support; a documentation update is a dependency there +11:34 < shimoda> s/expantion/expansion/ +11:35 < horms> wsa_: for basic support, i believe +11:35 < horms> i'll double check that +11:35 < horms> basucically i think we are talking about crash-bugs on 64bit +11:35 < wsa_> i see +11:36 < horms> probably the best things is for me to test things on 64bit, polish things up and post an rfc +11:36 < horms> with no special sauce +11:36 < horms> so i nominate that as my near term goal +11:36 < wsa_> sounds reasonable +11:37 < horms> one question i have; i assume the main use of this to us is nfs root. but that also seems not very useful to the people in europe +11:37 < horms> which is a good portion of us +11:37 < horms> am I reading things right? +11:37 < horms> shimoda: thanks +11:38 < geertu> At least NFS would allow to import/export files in the initrd +11:38 < wsa_> I mainly use initramfs, but my userspace needs are not very high... +11:38 < horms> geertu: good point +11:38 < geertu> But from my experience, just mounting NFS and writing a small file takes a minute +11:38 < horms> anyway, i'll work on it +11:39 < geertu> Right now I'd like to copy my HSCIF1 overlay dtbo to my initrd ;-) +11:39 < geertu> I could modify the initrd +11:39 < geertu> But for exporting, that doesn't work +11:39 < horms> so you tftp things once you are in usespace; in an ideal situation +11:39 < geertu> Probably we can set up an NFS root on the management VM, too? +11:40 < horms> probably +11:40 < geertu> AH, TFTP is an alternative +11:40 < geertu> Probably faster +11:40 < horms> i believe that is magnus's preferred method for himself +11:40 < wsa_> Yup, TFTP does it for me. Also, less to setup +11:40 < horms> but i agree a more local nfs server would be useful +11:41 < geertu> And we already have tftp setup on the management vm +11:41 < horms> but i think its somewhat off topic for this meeting +11:41 < geertu> yep +11:41 < horms> i think thats all for etheravb from me +11:41 < wsa_> thanks, simon +11:42 < wsa_> so, let's move to SCIF +11:42 < geertu> I submitted a new patch series last week +11:42 < wsa_> geertu has sent an awesome new series (actually two) which make DMA work now +11:42 < wsa_> so \o/ +11:43 < horms> yay indeed +11:43 < geertu> Major change is submitting the RX DMA request from the RX interrupt, which is what many other serial drivers do +11:43 < geertu> + lots of cleanups, and reordering of the patches to make more sense +11:44 < wsa_> did that give you any more insights about how all this affects non-Rcar SCIF and how/what could be backported to the BSP? +11:44 < geertu> I have to do more testing, though, as you may receive bogus data during overrunrs +11:45 < geertu> Non-R-Car SCIF* may be an issue +11:46 < geertu> We don't have DT-based DMA on any other ARM platform +11:46 < shimoda> wsa_: I think we don't need backport to the R-Car Gen2 BSP because it's maintenance mode +11:46 < geertu> kzm9g/armadillo/ape6evm use SCIFA for console, though +11:47 < geertu> in -legacy they had some DMA support, but it was not enabled for SCIFA (and didn't work when I tried to enable it on Armadillo) +11:47 < horms> do you have access to any of those boards? +11:47 < geertu> I have kzm9g/armadillo/ape6evm +11:47 < horms> a flush! +11:47 < geertu> So PIO SCIFA keeps on working +11:49 < geertu> I could try SCIFA DMA on e.g. Armadillo if I (1) revive -legacy and (2) try to fix the legacy shdma driver for modern residue handling (untested RFC patch posted) +11:49 < geertu> But in the long term, that's insignificant +11:49 < wsa_> i agree +11:49 < geertu> SCIF DMA was originally written for SH (sh7724?) +11:50 < geertu> hut never wired up in the sh platform code, so there are no users. +11:50 < geertu> s/hut/but/ +11:50 < geertu> So for now R-Car Gen2 (M2/koelsch) is what we have to work with +11:51 < wsa_> I think we are fine as long as PIO keeps working +11:51 < geertu> And Gen3 soon +11:51 < wsa_> on the old platforms +11:51 < wsa_> yes +11:51 < wsa_> is there any gain if I test them on lager? +11:51 < geertu> I think Shimoda-san already did, at least with the previous version +11:51 < wsa_> except that more testing is always a gain ;) +11:52 < geertu> On Koelsch, I test SCIF/SCIFA/SCIFB/HSCIF on EXIO +11:52 < shimoda> geertu: yes, I tested v2 version on lager. but i don't test v3 yet. +11:53 < geertu> BTW, SCIFB receive doesn't seem to work on one of the EXIOs. It may be a bug in pinctrl (code/doc) +11:53 < wsa_> so, gen2 bsp is in maintenance mode and gen3 bsp could pick up geert's patches as is? +11:54 < wsa_> or do we still have a version gap? +11:54 < wsa_> we talked last time about it +11:54 < geertu> I think Magnus would like the BSP team to switch over once my series is "finished" +11:54 < wsa_> yes, we would all like that, I assume :) +11:55 < horms> that makes sense to me unless there is a pressing need for it in the gen3 bsp in the near term +11:56 < wsa_> sounds good, i don't see any obstacles in how to go forward... +11:56 < shimoda> wsa_: about gen3 bsp plan, it uses upstream version (renesas-driver.git) until end of next year +11:57 < wsa_> next year? wow! +11:58 < wsa_> and yay! +11:58 < wsa_> so, that's it for SCIF? +11:58 < shimoda> oops, gen3 bsp target is "LTSI-2017". so, this might mean mid of next year +11:59 < geertu> I have one more question +11:59 < shimoda> anyway, bsp team looks upstream in this year +11:59 < geertu> What's up with the IRDA MSTP clock and SCIF2? +11:59 < wsa_> mid-2016 is still good IMO +12:00 < morimoto> IrDA on Gen3 is secret feature. +12:00 < morimoto> It will be removed from datasheet +12:00 < morimoto> and, please don't ask it on ML :) +12:01 < geertu> So there's a hole in the SCIFx MSTP2 range, and SCIF2 uses a clock from MSTP3 +12:01 < morimoto> About MSTP, IrDA and SCIF2 is using same one +12:02 < morimoto> Yes +12:06 < wsa_> ok +12:07 < wsa_> misc +12:07 < wsa_> i pulled in my i2c-slave updates +12:08 < wsa_> and I am currently scoping the rcar-i2c core to understand all the repeated start/NACK/auto retransmission issues we were seeing +12:09 < horms> shimoda san sent me a Kconfig fix for our ethernet drivers which has been merged +12:09 < wsa_> shimoda-san also got his PWM driver accepted \o/ +12:10 < horms> https://git.kernel.org/cgit/linux/kernel/git/davem/net.git/commit/?id=83bc805bff89854e4c81c67633a52ce1015b1502 +12:11 < wsa_> that was my misc part +12:11 < shimoda> wsa_: about PWM, yes, the PWM driver seems accepted but i cannot find the pwm maintainer git :) +12:12 < wsa_> yes, he said he will do the final changes but it is not clear if he actually did them +12:12 < geertu> git://git.kernel.org/pub/scm/linux/kernel/git/thierry.reding/linux-pwm.git +12:12 < geertu> it's part of renesas-drivers +12:14 < shimoda> oops, i meant that i could not find the PWM driver commit in his repo +12:16 < wsa_> so, final question would be when to meet next time +12:17 < wsa_> to be honest, I don't think we need the next meeting in two weeks. what about three weeks? +12:18 < wsa_> sorry, just found one thing +12:18 < wsa_> shimoda: what is the status about USB+IPMMU issues? +12:18 < horms> so far my evening schedule is open in both 2 and 3 weeks +12:18 < geertu> shimoda: It's indeed not included yet, probably because it's meant for v4.4 +12:19 < geertu> My schedule is open in both 2 and 3 weeks, except on Wednesdays +12:20 < shimoda> wsa_: no update for now +12:20 < shimoda> geertu: thank you for the checking +12:21 < geertu> shimoda: we have to have a bit more patience, as not many patches will be accepted between now and v4.3-rc1 +12:22 < geertu> (this also applies to the Gen3 patch stack!) +12:22 < morimoto> About next meeting, I don't want 16th Sep, other days are OK +12:22 < morimoto> 16th and 23th Sep +12:23 < wsa_> geertu: well, thierry could apply the new-driver-rule. but it is his choice, of course... +12:23 < horms> btw, 21, 22, 23 are holidays in the land of the rising sun +12:23 < wsa_> i suggest Sep 15th +12:23 < wsa_> same time +12:23 < morimoto> 15th Sep is OK for me +12:24 < horms> This time its in my schedule properly :) +12:24 < shimoda> geertu: I got it +12:24 < wsa_> \o/ +12:24 < shimoda> wsa_: 15th is OK to me +12:26 < geertu> booked +12:26 < morimoto> same here +12:26 < wsa_> great +12:27 < wsa_> that's it I assume +12:27 < wsa_> thank you! +12:27 < horms> wsa_: thanks +12:27 < geertu> thx +12:27 < morimoto> Thanks +12:27 < morimoto> Bye x2 +12:27 < wsa_> have a great evening/rest of day! +12:28 < shimoda> thank you, bye! +12:28 -!- shimoda [~shimoda@relprex2.renesas.com] has quit Quit: WeeChat 0.4.2 +12:28 < geertu> bye +--- Log closed Wed Aug 26 12:30:04 2015 diff --git a/wiki/Chat_log/20150901-core-chatlog b/wiki/Chat_log/20150901-core-chatlog new file mode 100644 index 0000000..9dfc6a6 --- /dev/null +++ b/wiki/Chat_log/20150901-core-chatlog @@ -0,0 +1,454 @@ +11:02 #periperi: < geertu> Welcome to the Core Group Chat Session! +11:02 #periperi: < uli___> good morning +11:02 #periperi: < horms> Thanks, nice to be back +11:02 #periperi: < geertu> Today's agenda: +11:02 -!- Irssi: Pasting 5 lines to #periperi.

+11:12 #periperi: < dammsan> by providing clock-output-name equivalent but from the driver? +11:12 #periperi: < geertu> the scif driver "works" (for scif2) as it assumes 115200 baud and doesn't program registers +11:13 #periperi: < dammsan> sure, i think that is the state of the entire CPG series +11:13 #periperi: < geertu> clk_of_get_parent_clock_name() looks in DT, it doesn't follow in-kernel clock topology +11:13 #periperi: < dammsan> maybe it should? +11:13 #periperi: < geertu> That's one option. +11:14 #periperi: < dammsan> so say it would work, then isn't omitting that parameter from DT a good idea? +11:14 #periperi: < geertu> I think "no clock-output-names" is meant for clocks with a single output, where the node name can be used instead +11:14 #periperi: < dammsan> ok i see +11:14 #periperi: < dammsan> so we could have one node per clock instead +11:14 #periperi: < geertu> It may be a good idea if the driver knows (like cpg) +11:14 #periperi: < dammsan> or perhaps we should extend the core to support index? +11:15 #periperi: < geertu> For mstp the driver doesn't know, so it comes up with mstp3.10 +11:15 #periperi: < geertu> I'd like to wait for the clock people's response +11:15 #periperi: < dammsan> the cpg driver could do the same +11:15 #periperi: < dammsan> since we have the strings there anyway +11:15 #periperi: < geertu> Clocks work again just by re-adding clock-output-names to the dtsi only (no driver update needed) +11:16 #periperi: < dammsan> waiting for maintainer feedback is of course a good plan +11:16 #periperi: < dammsan> but is there something we could do in the meantime? +11:16 #periperi: < dammsan> we could re-add clock-output-names like you say +11:16 #periperi: < dammsan> or just fix the code in the cpg driver +11:16 #periperi: < geertu> It's not a problem in the cpg driver +11:16 #periperi: < geertu> and it can't be fixed there +11:17 #periperi: < geertu> only in core clock code +11:17 #periperi: < dammsan> oh, but this only triggers in the case of CPG and not in MSTP, right? +11:17 #periperi: < geertu> It doesn't trigger in mstp, because the only users of mstp clocks are devices, where clk_get() will do the right thing. +11:18 #periperi: < geertu> If you register e.g. a fixed-factor-clock as a child of an mstp clock, it will fail, too +11:18 #periperi: < dammsan> ok then consider me convinced =) +11:18 #periperi: < horms> +1 +11:19 #periperi: < geertu> Basically it fails for every clock in DT where the parent has multiple clock outputs +11:19 #periperi: < dammsan> so we should wait for feedback? +11:20 #periperi: < dammsan> or does anyone feel like cooking up some core CCF code? =) +11:20 #periperi: < dammsan> maybe i simply misunderstood mike turquette +11:20 #periperi: < geertu> Not me, because I think the "no clock-output-names rule" is flawed +11:22 #periperi: < geertu> Any other upcoming gen3 work (irqc is already in the task list)?

=) +11:52 #periperi: < dammsan> but seriously, what a mess +11:52 #periperi: < geertu> we can bitbang SDHI2 WP/CD on those lines +11:52 #periperi: < geertu> or GPIO ;-) +11:52 #periperi: < geertu> U-boot uses scif2 +11:52 #periperi: < dammsan> hehe, must be better +11:52 #periperi: < dammsan> but u-boot is not interrupt driven =) +11:53 #periperi: < geertu> Obviously the interrupt is working +11:53 #periperi: < horms> if a patch can already be found by google then it ain't no secret anymore +11:53 #periperi: < dammsan> maybe we should just ask for update for the SCIF2 interrupt +11:53 #periperi: < dammsan> update for the deocumentation +11:53 #periperi: < dammsan> shimoda: morimoto: can we request update?

+12:44 #periperi: < pinchartl> horms: if you can send an RFC and CC me I can follow up on it and assist during review. would that be ok ? +12:45 #periperi: < horms> sure, I'll see what i can do +12:45 #periperi: < geertu> OK, let's see +12:45 #periperi: < dammsan> so we are still aiming PFC at v4.4, right? +12:45 #periperi: < dammsan> and same for CPG i think? +12:46 #periperi: < geertu> yes +12:46 #periperi: < dammsan> does that mean that this new API needs to have some sort of agreement before that? +12:46 #periperi: < geertu> yes +12:47 #periperi: < geertu> else we'll have code for both on gen3 +12:47 #periperi: < dammsan> geertu: but your reset controller can be done in parallel with this, right?

+12:50 #periperi: < pinchartl> what is our current target ? v4.4 or v4.5 ? +12:50 #periperi: < geertu> "generic,v4.4,Propose API to obtain mode pin values in a a generic way" task added +12:50 #periperi: < geertu> v4.4 +12:50 #periperi: < pinchartl> let's see if it's possible for v4.4. the discussion needs to be started sooner than later then +12:51 #periperi: < pinchartl> and then let's decide based on the feedback +12:51 #periperi: < dammsan> oh yeah +12:51 #periperi: < geertu> ok +12:51 #periperi: < dammsan> we can agree that syscon is a good plan B? +12:52 #periperi: < pinchartl> well, it's the only backup plan I see :-) +12:52 #periperi: < dammsan> we have the built-in register access in the CPG right now +12:52 #periperi: < dammsan> which is ultra-short-term +12:53 #periperi: < dammsan> pinchartl: for the new API, can you target Gen2?

"clock-output-names" +11:24 < geertu> i.e. CPG +11:25 < geertu> I guess everybody saw the email from Mike Turquette +11:25 < horms> aye +11:25 < dammsan> yeah +11:25 < uli___> mhm +11:25 < dammsan> and the conclusion is? +11:25 < horms> I deffer to dammsan's conspiracy theory +11:25 < dammsan> haha +11:26 < dammsan> at least we can move forward now by using clock-output-names to begin with, right? +11:26 < horms> yes +11:26 < horms> that is my understanding +11:26 < dammsan> or did i misunderstood things? +11:26 < geertu> As I don't think Mike's rework will be in v4.4 (too late), I think we should (re)add clock-putput-names +11:26 < dammsan> good +11:26 < horms> and mike can futs around with his ideas +11:26 < dammsan> yeah, i think so too +11:27 < horms> assuming we do that, what are the next steps, e.g. for v4.4? +11:27 < dammsan> seems pretty clear to me +11:27 < geertu> So people have to resend their integration patches, preferably in the right order to make Simon's work easier +11:27 < horms> yes, ideallt +11:27 < horms> yes, ideally +11:27 < dammsan> may i suggest aligning this update with the new data sheet? +11:27 < horms> though i'm trying a hub-and-spoke appraoach +11:27 < geertu> futs is not in my dictionary, nor in "dict fut"? +11:28 < dammsan> morimoto: when is the new updated datasheet coming? +11:28 < geertu> new data sheet? +11:28 < horms> futs ~= play around with +11:28 < dammsan> yourself? +11:28 < dammsan> =) +11:28 < morimoto> dammsan: there is still no information about datasheet +11:28 < horms> though i'm trying a hub-and-spoke appraoach; so dependencies may not be as bad as you may think +11:29 < geertu> As long as you're adding a new mstp register, it's OK +11:29 < horms> yes +11:29 < geertu> But some patches touch existing MSTP registers, so they may conflict +11:29 < horms> yes +11:29 < horms> that is the hard part +11:29 < dammsan> horms: so what is your plan regards to merging? +11:29 < horms> likewise with dt nodes +11:30 < horms> upstream? +11:30 < dammsan> yeah +11:30 < horms> i think we can start to push things into next +11:30 < horms> and thus towards arnd & the gang +11:30 < dammsan> something in parallel with the PFC and CPGbits? +11:30 < horms> i think that would be idea +11:30 < horms> what do you think? +11:30 < dammsan> sure, just keep it small +11:30 < horms> ok +11:30 < dammsan> i suppose you will get some feedback =) +11:31 < horms> i was thinking of using separate branches for the arm64 work +11:31 < horms> so it can be comented on separeately to the 32bit work +11:31 < dammsan> sounds good +11:31 < geertu> For integration? +11:31 < horms> I will also stock up on various colours of paint +11:31 < geertu> Or for drivers? +11:32 < horms> I was reffering to integration +11:32 < geertu> Since that's arm64, it's indeed best to use a separate branch +11:32 < horms> indeed +11:32 < geertu> or is that not how arm-soc works for mixed arm32/arm64 SoC manufacturers? +11:33 < horms> we will soon find out! +11:33 < geertu> :-) +11:33 < dammsan> geertu: we should focus on cache topology in the not so distant future too +11:33 < horms> I'm pretty sure I will need to make a trip to Google to chat to Olof at some point; thats what it took to get the 32bit stuff flowing nicely +11:33 < geertu> Let's hope they give earlier feedback then for your now-pending pull requests +11:33 < dammsan> i guess that is topic 1 more, sorry for late addition +11:34 < horms> geertu: i am skeptical +11:34 < geertu> (added task "r8a7795,v4.5,Cache topology") +11:35 < horms> dammsan: how about you start by reposting a patchset that you think is appropriate for v4.4? +11:35 < geertu> horms: I have lots of platform_data removal patches waiting for the arm-soc pull completion +11:35 < horms> in relation to that mess +11:35 < geertu> horms: Trip to ELCE? +11:35 < dammsan> horms: i think my latest patchset covers a minimal base pretty well +11:35 < horms> i plan to repost the dt/fixes separately soon +11:36 < dammsan> and i may not have time to resend until after ELCE +11:36 < horms> but i don't know when olof et al.. will actually pull anything +11:36 < horms> dammsan: does it need updating? +11:36 < dammsan> horms: how about i update the CPG series +11:36 < geertu> they seem to be busy with pulling various for-v4.3 stuff +11:36 < geertu> Topic 3. [PATCH/RFC v2 0/4] Renesas CPG/MSTP DT Binding Proposal +11:36 < dammsan> and then add some incremental patch that perhaps you can fold in? +11:37 < geertu> Has anyone read that? +11:37 < horms> geertu: thats nice, seeing that closed about a month ago +11:37 < geertu> I know it may be a bit late, but I was triggered again by some RST discussion +11:38 < geertu> R-Car Gen3 gained many more module stop/status/reset/... registers, now we have up to 10(!) sets +11:38 < horms> is this related to the mode pin (driver) discussion (with Luarent)? +11:38 < dammsan> geertu: i got a bit confused by MSSR? +11:38 < geertu> horms: no +11:39 < dammsan> this is how things are called for Gen2 or Gen3? +11:39 < geertu> 8A. Module Standby, Software Reset +11:39 < horms> ok, could you add that to the agenda, possibly for next time when he is here +11:39 < horms> ? +11:40 < geertu> 8A. Module Standby, Software Reset (Gen3) +11:40 < geertu> 7A. Module Standby and Software Reset (Gen2) +11:40 < dammsan> geertu: but isnt 7. and 8. CPG? +11:41 < geertu> Section 2. Module Standby, Software Reset (APE6) +11:41 < dammsan> I see +11:42 < geertu> yes, 7 and 8 are CPG +11:42 < dammsan> I've never seen MSSR before so I got a bit surprised +11:42 < dammsan> wasn't sure what it was +11:42 < dammsan> but now i understand +11:42 < geertu> The abbreviation is never used in the datasheet +11:42 < dammsan> were you planning on using that for DT compat strings? +11:43 < geertu> Yes, as it must be different from the existing +11:43 < dammsan> i think that was included in your proposal +11:43 < dammsan> geertu: you can match on soc-specific string too, right? +11:44 < geertu> and there would be a single mssr block, not individual blocks for the individual registers (which was the biggest problem for the 10 register sets) +11:44 < geertu> compatible = "renesas,r8a7791-cpg-mssr"; +11:44 < geertu> compatible = "renesas,r8a7795-cpg-mssr"; +11:44 < pinchartl> geertu: I'm in Belgium right now and totally jetlagged, sorry for not joining earlier +11:44 < geertu> Welcome! +11:46 < dammsan> geertu: you remedy the MSTP bit index issue in your proposal, right? +11:46 < dammsan> with split <&mstp5 R8A7790_DU0> +11:46 < geertu> You mean using register and bit index that don't match? +11:46 < dammsan> yeah +11:46 < dammsan> exactly +11:46 < geertu> Yes. +11:46 < dammsan> good. +11:47 < geertu> #define MSTP(n) (n / 100 * 32 + n % 100) +11:47 < geertu> Originally I wanted to use just e.g. " +11:47 < geertu> 318" +11:47 < geertu> Until I realized what kind of sparse arrays that would give +11:48 < geertu> So it;s translated to 3 * 32 + 18 +11:48 < dammsan> do we have issues with sparsely populated arrays? +11:48 < dammsan> i thought the DT map callback takes care of that +11:48 < horms> so its ~3 times more densely populated? +11:48 < geertu> clks = kmalloc(MSTP_MAX_CLOCKS * sizeof(*clks), GFP_KERNEL); +11:49 < geertu> For 12 registers of 32 bits, that would be 1200 instead of 12 * 32 entries +11:50 < dammsan> ok, i thought you were talking about DT size +11:50 < geertu> of xlate onecell needs a non-sparse array +11:50 < geertu> No, in DT clocks/clock-indices/clock-output-names contain the used entries only +11:50 < dammsan> ok, so DT does not use the MSTP() macro? +11:51 < geertu> They become large though, so you have to be careful to insert new entries at the right position +11:51 < geertu> include/dt-bindings/clock/r8a7791-clock.h has e.g. +11:51 < geertu> #define R8A7791_CLK_MSIOF2 MSTP(205) +11:51 < geertu> and the dtsi just uses R8A7791_CLK_MSIOF2, which is expanded to 2 * 32 + 5 +11:51 < dammsan> oh, that looks good +11:52 < geertu> And we avoid the "CCF doesn't support clock-cells = <2>" by Laurent +11:52 < dammsan> the in-driver management for clock arrays is an interneal implementation detail +11:53 < horms> is it possible to teach of xlate oncell how to handle a sparse array? +11:53 < pinchartl> geertu: that looks good to me +11:54 < geertu> See of_clk_src_onecell_get() +11:55 < geertu> horms: we can provide our own xlate method in +11:55 < geertu> of_clk_add_provider(np, of_clk_src_onecell_get, &group->data); +11:55 < dammsan> geertu: so how do we combine that and the current CPG series? +11:56 < geertu> Then we can get rid of the MSTP() macro, I think +11:56 < dammsan> horms: geertu: it would be elegant to use xlate if that would solve the issue +11:57 < geertu> pinchartl: which part? +11:57 < geertu> horms: yes +11:57 < horms> great :) +11:58 < pinchartl> geertu: the DT bindings with a single node +11:58 < geertu> dammsan: the clk-mssr driver must be added, and the call to cpg_mstp_add_clk_domain() has to be changed to cpg_mssr_add_clk_domain(), and the Makefile updated to use clk-mssr.o +11:58 < pinchartl> I haven't reviewed the implementation in detail +11:59 < geertu> pinchartl: I should have sent a git-style diff, so you could see more easily how clk-mssr.c differs from clk-mstp.c +11:59 < pinchartl> no worries +11:59 < pinchartl> implementations can always be adjusted later if needed anyway +12:00 < geertu> My biggest worry is the long clocks/clock-indices/clock-output-names arrays +12:00 < geertu> They're still error-prone +12:01 < dammsan> geertu: are those arrays per-32bit-word? +12:01 < dammsan> or one global? +12:01 < geertu> dammsan: no, they cover all MSSR moule bits +12:01 < geertu> s/moule/module/ +12:01 < dammsan> oh i see +12:02 < dammsan> would it be difficult to do it per-32bit-word? +12:02 < dammsan> that would make it easier to review and less error prone, no? +12:02 < geertu> So we need subnodes per 32-bit register (set)? +12:03 < geertu> mssr@0 { ... } +12:03 < dammsan> that sounds logical to me +12:03 < geertu> mssr@1 { ...} +12:03 < geertu> Can be done, more parsing code +12:04 < geertu> And people may still stick the wrong clocks in the wrong subnode +12:04 < dammsan> i guess we're one step away from a single plink per clock? +12:04 < geertu> it woukd avoid the "/* MSTPx */" comments +12:04 < geertu> That was my previous proposal ;-) +12:05 < geertu> For the subnodes, we need some more #address/size-cells and reg glue +12:05 < dammsan> one big array seems a bit suboptimal to me... +12:05 < dammsan> i like the single plink +12:06 < dammsan> but other people may not =) +12:06 < geertu> Yeah, Gen2 doesn't have register set 6 +12:06 < dammsan> geertu: do you need reg glue? +12:06 < geertu> so says the datasheet +12:06 < geertu> but there are bits I can toggle from U-Boot, and the status registers follow suit ;-) +12:06 < dammsan> hehe +12:07 < geertu> THe mssr main node needs #address-cells is 1, #size-cells = 0 +12:07 < geertu> The mssr@x subnodes need reg = <x> +12:07 < dammsan> i see +12:08 < geertu> In theory, the subnodes also need #clock-cells = <1> +12:08 < geertu> but dtc won't complain about that +12:08 < geertu> ah, CCF needs the #clock-cells = <1> in the subnodes +12:08 < geertu> That would be the penalties for getting rid of the "/* MSTP x */" comments in the arrays +12:09 < geertu> But I think we're running out of time... +12:09 < dammsan> i'm fine either way myself +12:09 < geertu> Please reply with your comments to the emails +12:09 < geertu> Topic 4. sh-pfc +12:09 < dammsan> lets discuss face-to-face how to combine these things +12:10 < dammsan> but i'll reply any technical feedback via email +12:10 < dammsan> yes +12:10 < dammsan> nice with the pfc bits +12:10 < geertu> So I queued up the pfc patches +12:10 < geertu> both Gen3 and non-Gen3 +12:11 < geertu> Most have been acked by LinusW +12:11 < geertu> some by Laurent +12:11 < geertu> I have more PFC patches to go out (resend) +12:12 < pinchartl> geertu: if there are core PFC patches I haven't acked could you please ping me ? +12:12 < horms> Excellent, thanks for getting that under control +12:12 < geertu> But MSIOF (and USB (Shimoda-san?)) depends on review comments for "[PATCH] [RFC] pinctrl: sh-pfc: Improve pinmux macros documentation" +12:12 < pinchartl> I won't have time to review the "pin number" patches this week +12:12 < pinchartl> but I can take a look at the core +12:12 < pinchartl> ok, that one I should review I guess :-) +12:12 < geertu> pinchartl: OK; yes ;-) +12:14 < geertu> shimoda: Ignore me, USB on Gen3 doesn't need it (Gen2 did) +12:14 < morimoto> geertu: thank you about this patch. I guess it was my task +12:15 < geertu> morimoto: you're welcome. There's still opportunity for improvement +12:15 < shimoda> geertu: sorry, and I don't understand about the pfc topic +12:15 < geertu> shimoda: pfc-r8a7791.c has "PINMUX_DATA(USB0_PWEN_MARK, FN_USB0_PWEN)" +12:15 < geertu> which uses the "raw +12:16 < geertu> which uses the "raw" PINMUX_DATA() macro +12:18 < pinchartl> (lunch time) +12:18 < geertu> Topic 5. Status check for tasks from last meeting - what is remaining +12:18 < shimoda> Umm, I don't still understand it, so I will ask Morimoto-san or Magnus-san later :) +12:18 < dammsan> shimoda: sure +12:19 < geertu> https://osdr.renesas.com/projects/linux-kernel-development/wiki/Core-todo-list +12:19 < geertu> No status changes? +12:19 < horms> I did some work on Lauren't pin mode driver idea, however I'm struggling to initialise the module(s) early enough for them to be useful to CPG on Gen2 which is used from the init_timer callback +12:20 < dammsan> horms: i wonder if some -EPROBE_DEFER changes would be useful for the CPG and/or CCF? +12:20 < pinchartl> horms: could init be performed on the first call to the get mode operation and the value then cached ? +12:20 < pinchartl> (now I really have to run, sorry) +12:20 < dammsan> and move it to later during boot +12:20 < geertu> pinchartl: bye! +12:21 < dammsan> pichartl: enjoy lunch +12:21 < horms> pinchartl: the trouble is knowing which implementer (module) to call +12:21 < horms> it needs to register itself for your idea to work +12:21 < horms> dammsan: that may work out, the devil would be in the details +12:21 < dammsan> horms: can't you use a different earlier initcall? +12:22 < horms> esp what needs a cpg to be functional at that point +12:22 < dammsan> earlier than the timer callback +12:22 < horms> i tried early +12:22 < horms> and even pure +12:22 < horms> they are both too late +12:22 < dammsan> hm.. +12:22 < geertu> machine_desc.init_early()? +12:22 < dammsan> we have the delay stuff there i think +12:22 < horms> geertu: that would work, i suppose +12:23 < horms> but it would need to call the implementor directly +12:23 < horms> rather than the higher-level wrapper; which imho is most of the point of the idea +12:23 < horms> none the less it might make it fly for gen2 +12:23 < horms> and perhaps for gen3 an initcall is early enough +12:24 < geertu> machine_desc.init_early() can set up the accessor? +12:24 < dammsan> horms: clocks and timers are a can a worms regardless of architecture +12:24 < geertu> dammsan: you don't want -EPROBE_DEFER in CCF nor CPG, as it won't be retried +12:24 < horms> geertu: yes, it could set up the accessor or cache the value; your idea is growing on me +12:25 < horms> i'll see if I can make it fly +12:25 * geertu should shut up, as he wants renesas,modemr to succeed +12:25 < horms> and if so post a prototype +12:25 < horms> fwiw, i am currently neutal regarding wich solution i would like to succeed +12:25 < horms> my aim is merely to flesh out laurent's idea so we can see what it looks like in practice +12:26 < horms> thanks for the idea +12:26 < dammsan> geertu: i guess moving CPG and CCF to later on will require some serious changes then +12:26 < horms> i think we can close that sub-topic for noe +12:27 < horms> i'm skeptical that such a rework is warranted for this particular cause +12:27 < dammsan> geertu: what is your plan regards upstreaming of the PFC bits? +12:27 < dammsan> you said sending something at -rc i recall? +12:27 < dammsan> horms: sure +12:27 < dammsan> horms: just plan b if all else fails +12:27 < horms> sure +12:27 < horms> no argument there +12:28 < geertu> dammsan: send pull request to LinusW later this week, or perhaps next week (hmm, Dublin) +12:28 < geertu> Are there many pending PFC bits? +12:28 < geertu> I have HSCIF and MSIOF +12:28 < geertu> Shimoda-san has USB? +12:29 < dammsan> does linusw like several incremental pull requests, or one single? +12:29 < horms> you have avb, right? +12:29 < geertu> damsan: no ides. I may find out ;-) +12:29 < shimoda> geertu: yes, I have USB (and PWM) +12:29 < geertu> avb is in +12:29 < horms> great +12:29 < morimoto> I guess I posted Sound and I2C +12:29 < dammsan> i think if we can get in what we have then that would be wonderful +12:30 < horms> agreed +12:30 < geertu> sh-pfc-for-v4.4 has scif, i2c, audio clock, audio ssi, avb +12:30 < dammsan> maybe we can consider the DT bindings semi-stable once things hit next?

+12:32 < dammsan> i think that is fine +12:33 < horms> its not as if it will regress any existing support +12:33 < geertu> Yeah, we had small bugs in various PFC bits for years +12:33 < horms> exactly +12:33 < geertu> They will be fixed when/if someone encounters them +12:33 < dammsan> untested most certainly means broken +12:34 < horms> yes +12:34 * geertu is actually surprised about how much of the PFC bits were correct +12:34 < dammsan> yeah +12:34 < dammsan> good with review from you guys +12:35 < dammsan> and nice that morimoto-san broke out the mega-patch +12:35 < morimoto> I hope 7795 is more readable than other pfc +12:35 < dammsan> i wonder if linusw will be at ELCE +12:35 < dammsan> if so i should bring some whiskey +12:36 < geertu> "bring some whiskey to Ireland"? +12:36 < dammsan> haha +12:36 < dammsan> well +12:36 < dammsan> sand to the beach +12:36 < horms> dammsan: I heard that Dublin is a dry county +12:37 < dammsan> as long as my coffee comes with medicin i'm happy +12:38 < dammsan> geert: would it be possible for you to prioritize sending out the PFC bits to linusw before ELCE? +12:38 < dammsan> i will do my best to update CPG on thursday +12:39 < geertu> dammsan: sure +12:39 < dammsan> thanks! +12:39 < dammsan> horms: and after ELCE i hope to hand over the integration stuff to you +12:39 < horms> dammsan: excellent +12:40 < horms> i guess there wont be a whole lot of time between then and rc5 +12:40 < dammsan> i guess so +12:40 < dammsan> alternatively i can hand it over earlier +12:41 < horms> earlier is better if its ready :) +12:41 < dammsan> i need to sync the CPG and integration bits +12:41 < horms> but do we need bindings to hit next first? +12:41 < dammsan> i think review can happen in parallel +12:41 < horms> ok +12:41 < horms> that is of course fine +12:41 < dammsan> will you be busy next week? +12:41 * horms checks +12:42 < dammsan> or if i could hand over integration stuff to you earlier +12:42 < dammsan> perhaps that may improve our chances +12:42 < horms> I don't expect to be busy next week +12:42 < dammsan> ok, so i should really send out both CPG and integration this week +12:42 < dammsan> geert: will you be online on thursday? +12:43 < horms> or the week after other than friday when i am shceduled to visit musashi works +12:43 < dammsan> but the earlier the better +12:43 < horms> the last week of October will be busy for me +12:43 < dammsan> geertu: i was hoping to chat with you how to integrate your CPG/MSSR proposal +12:43 < dammsan> will thursday be ok? +12:44 < horms> dammsan: probably its best if you handle both of those series as you are most familiar with them. but if it makes sense I could try to offload you a bit somehow +12:44 < geertu> dammsan: Thrusday is fine +12:45 < dammsan> horms: i agree, but i may ask you to do some folding yourself +12:45 < dammsan> horms: when will your new board arrive? +12:46 < horms> it was scheduled to arrive today, but didn't +12:46 < dammsan> geertu: thanks, lets chat more thursday then +12:46 < dammsan> ok +12:46 < dammsan> i will install two new boards in the remote rack tomorrow btw +12:46 < horms> is there anything special i need to know about hooking it up? +12:47 < dammsan> horms: nope +12:47 < dammsan> it is noisy +12:47 < shimoda> horms: I'm sorry I sent the board today, so it should arrive tomorrow +12:47 < horms> ok +12:47 < horms> shimoda: no problem! +12:47 < geertu> BTW, does anyone have a kzm9d? +12:47 < horms> yes +12:48 < horms> though its semi-broken these days; the kernel for it that is +12:48 < dammsan> horms: if you are not using it, can i hook it up for remote access? +12:48 < geertu> horms: I don't need a running kernel ;-) +12:48 < horms> i'm only semi-using it to test kernels +12:48 < horms> that don't boot +12:48 < horms> perhaps i could send it to dammsan ?

So, I will get information from them later +11:17 < geertu> SCIF DMA is in -next +11:17 < geertu> So it will be in v4.4 +11:17 < wsa_> \o/ +11:18 < wsa_> didn't notice from the mails in linux-sh +11:18 < wsa_> so i can remove +11:18 < wsa_> SCIF,4.4,Upstream improved DMA support for R-Car Gen2 +11:18 < wsa_> from the todo list +11:18 < wsa_> ? +11:19 < geertu> GregKH's bot didn't CC linux-sh +11:19 < geertu> Yes (assumed in -next == will be in v4.4) +11:19 < wsa_> shimoda: ok, will update the info about thermal driver +11:20 < wsa_> geertu: and you will be working on baudrate generators for 4.5, correct? +11:20 < geertu> that's correct +11:20 < geertu> I'm a bit delayed by the Gen3 CPG rework +11:21 < wsa_> I can imagine +11:22 < wsa_> geertu: anything else you are planned to work on IO wise? +11:22 < morimoto> I asked about SPI slave use case to BSP team +11:22 < wsa_> I have this baudrate generator and random SPI stuff in the list :) +11:23 < geertu> Yeah, I plan to test MSIOF on Gen3, if possible (read: available on EXIO) +11:23 < wsa_> same questions to the others +11:23 < wsa_> shimoda: I assume you will be busy doing USB stuff? +11:24 < wsa_> morimoto: any IO related task you have assigned? (except using I2C for sound ;)) +11:24 < morimoto> Ahh... no I/O I have +11:24 < wsa_> simon: I guess you'll work in improving EtherAVB support? +11:25 < shimoda> wsa_: yes, but bsp team needs USB stuff (expect USB2 host) until end of May +11:25 < shimoda> so, i have some space +11:25 < wsa_> oh, that sounds good +11:25 < morimoto> wsa_: About Thermal driver lacking docs, do you mean 10A.3.1.2 ? +11:25 < horms> EtherAVB is the only i/o related item i'm working on directly +11:25 < shimoda> however, sometimes I have a lot of paper works though :) +11:26 < wsa_> oh, that sounds not good +11:26 < wsa_> :) +11:27 < wsa_> horms: anything specific? I have only PTP support until End of November in the list +11:27 < horms> so my question for shimoda-san is about that +11:27 < horms> is now a good time? +11:28 < wsa_> morimoto: yes, and 10.A.3.1.4 +11:30 < shimoda> horms: sorry I don't understand your question +11:30 < shimoda> you are talking about PTP support? +11:31 < horms> my quesion is as follows +11:32 < morimoto> wsa_: OK, according to datasheet team, about 10A.3.1.2, it depends on real measured data. +11:32 < morimoto> but, there is not such data at this point. So, it will be other explanation in next datasheet +11:32 < morimoto> if they still doesn't have it +11:33 < horms> I see some PTP support present in the ravb driver. It looks like it handles timestamps. Is that what is required for r8a7795 by mid-November? +11:33 < wsa_> morimoto: I assumed so. Anyhow, looks like BSP team took this over. They will probably have better access to such data +11:36 < shimoda> horms: thank you for the detail. I will ask bsp team about this +11:36 < horms> shimoda: thanks. if they want to explain things in patches that is fine by me :) +11:37 < wsa_> good +11:38 < wsa_> can we move to SDHI topic? +11:38 < horms> i think so +11:38 < shimoda> i think so +11:39 < wsa_> fine +11:39 < wsa_> It seems that BSP team also wants to do the initial support? +11:39 < wsa_> And then wants to work on DMA support? +11:40 < shimoda> I think they want to work on DMA support if possible +11:40 < wsa_> And they need some assistance from us how to do it +11:41 < shimoda> I think so +11:43 < wsa_> do they have patches for initial support already? +11:43 < shimoda> tmio driver is using dmaengine. but I don't know gen3 SDHI should use it or not +11:44 < shimoda> wsa_: for PIO, yes +11:44 < shimoda> let me check some repositories +11:47 < shimoda> in renesas-bsp.git, 91e3cc719def606e049861d4f9fc02bd90f126be, arm64: dts: salvator-x: Add sdhi-rcar support +11:48 < shimoda> 09a0662a2b6073bb2237b5d28a354a406b4b640b, arm64: dts: r8a7795: Add sdhi-rcar support +11:49 < wsa_> got them +11:50 < wsa_> and some more patches to look at +11:50 < shimoda> about driver side, they are submitted some local patches... +11:50 < horms> wsa_: btw renesas-bsp is on kernel.org +11:52 < wsa_> yes, that's good +11:53 < wsa_> well, the makefile from mmc/hosts says: +11:53 < wsa_> tmio_mmc_core-$(subst m,y,$(CONFIG_MMC_SDHI)) += tmio_mmc_dma.o +11:53 < wsa_> so, the DMA module is only compiled in for SDHI? +11:54 < wsa_> ah, sure. the todo list only marks "DMA on Gen3" as a todo +11:55 < shimoda> wsa_: yes, on gen3, DMAC is internal in the SHDI device instead of SYS-DMAC +11:57 < wsa_> is this internal DMAC reused in other IP cores? +11:57 < wsa_> it doesn't look SDHI specific to me +11:58 < shimoda> I don't think this internal DMAC is reused +12:01 < wsa_> ok +12:02 < morimoto> About makefile, tmio_mmc_dma.o is used only from CONFIG_MMC_SDHI is correct +12:02 < morimoto> this is because historical reason +12:02 < morimoto> About Gen3 internal DMAC, this is Gen3 new feature +12:02 < morimoto> Gen3 DMAC != tmio_mmc_dma +12:02 < wsa_> I'd think a new file 'tmio_mmc_dma_gen3.c' or similar would be the way to go, but I need to double check +12:03 < wsa_> I can investigate +12:03 < wsa_> Is it "as soon as possible" or will next week be enough? +12:03 < morimoto> I think it is not "tmio", "sh_mobile_sdhi_dma" is better ? +12:04 < horms> can we rename tmio_mmc_dma while we are at it? +12:04 < wsa_> to? +12:04 < horms> I suspect it doesn't relate to tmio at all +12:04 < horms> but just to sdhi +12:05 < horms> i could be wrong +12:05 < wsa_> i will dig into that and post my findings on the list +12:05 < morimoto> unfortunately, not good idea +12:05 < morimoto> because tmio_mmc_pio calls tmio_mmc_dma function +12:06 < horms> ok +12:06 < morimoto> But, we can create new sub-framework for DMA? +12:06 < morimoto> real TMIO doesn't need DMA (?), we need 2type of DMA +12:07 < morimoto> and tmio_dma naming is not good match now ? +12:07 < horms> probably that will lead to a nice clean result +12:07 < horms> but is gen3 dma on the critical path? +12:08 < horms> If so it would be nice to arrange things so new frameworks come after hw support, imho +12:08 < wsa_> agreed +12:08 < shimoda> horms: on the critical path or not, let us ask BSP team tomorrow :) +12:09 < horms> good plan +12:09 < wsa_> anything more for SDHI? +12:09 < wsa_> otherwise let's move on to watchdog +12:11 < morimoto> ok +12:11 < wsa_> ok, my idea there is to implement the missing SET_TIMEOUT feature and repost as RFC +12:12 < wsa_> we can then test this one on Gen2/3 and see if it works with the reset controllers +12:12 < wsa_> (it obviously doesn't on r8a7790 ES1) +12:12 < wsa_> if all fails, I could try to add r7s72100 support and get at least the driver upstream vis this path +12:13 < wsa_> so we don't have to carry around this one +12:13 < wsa_> OK plan? +12:13 < shimoda> wsa_: if we use not SMP, watchdog should work even if r8a7790 ES1 +12:14 < geertu> The watchdog is not limited to R-Car Gen2/3 and RZ +12:15 < wsa_> shimoda: Yes, then it works +12:15 < wsa_> I can confirm that +12:15 < geertu> it's also present on older SH-Mobile and R-Mobile +12:16 < wsa_> geertu: like with r7s or even another register layout? +12:17 < geertu> BTW, the issue with the syscon driver I mentined in "Re: [RFC 4/5] ARM: shmobile: r8a7790: let rst module allow watchdog resets if desired" (http://www.spinics.net/lists/linux-sh/msg39799.html) is gone +12:19 < wsa_> how come? +12:20 < geertu> At that time, you couldn't have both syscon and a regular driver bind to the same device node +12:20 < geertu> that has been fixed +12:20 < geertu> the APE6 RWDT looks the same as Gen2 +12:21 < geertu> The RZ one is different +12:22 < geertu> A1/AG5 uses an 8-bit version of APE6/Gen2 +12:22 < geertu> So there are 3 versions +12:23 < wsa_> ah, okay, so we still need the "syscon" property somewhen +12:23 < geertu> But "It's slightly more complicated there, as we already have a driver for the +12:23 < geertu> SYSC on R-Mobile (rmobile-reset), and a device node can't be bound +12:23 < geertu> by both the syscon and the rmobile-reset driver. +12:23 < geertu> " is no longer true +12:25 < geertu> From a chat with Magnus a long time ago: " +12:25 < geertu> Looking at datasheets, it seems the RWDT has a long history. +12:25 < geertu> R-Car Gen2: 32-bit registers, using RST +12:25 < geertu> R-Mobile APE6: 32-bit registers, using SYSC (APE6 has no RST block) +12:25 < geertu> SH-Mobile AP4/AG5, R-Mobile A1: 16-bit registers with 8-bit (instead of 16-bit) watchdog counter +12:25 < geertu> But the core is similar. +12:25 < geertu> And of course AP4 and A1 are single-core" +12:25 < geertu> RZ has a different control register layout +12:26 < wsa_> ok, i have datasheets for all of them +12:27 < wsa_> well, then, i'll do as I said before +12:27 < geertu> I can test A1/AG5/APE6 +12:27 < wsa_> since there were no complaints ;) +12:27 < geertu> and M2 and H3, of course +12:27 < wsa_> geertu: \o/ +12:28 < wsa_> I ran out of topics +12:28 < shimoda> About H3, as I wrote periperi ML, we can not write RST +12:28 < shimoda> :) +12:28 < wsa_> :) +12:28 < wsa_> anything from your side left?

Advanced Power Management Unit for AP-System Core (APMU) +11:09 < mturquette> ah +11:09 < geertu> The registers in 7A are inside the same 4 KiB block of the CPG registers +11:09 < geertu> The registers in 7B are in a separate 4 KiB block +11:09 < dammsan> mturquette: i think so +11:11 < dammsan> I guess 7B needs to be managed by PSCI firmware +11:11 < geertu> Same for Gen3 (chapters 8/8A/8B) +11:11 < dammsan> geertu: do you have any strong feelings about the compat string name? +11:12 < geertu> The CPG and MSSR registers are really mixed, so you cannot separate them +11:13 < dammsan> right, so this is a good match for the single DT node approach +11:13 < geertu> dammsan: I just came up with a name that describes the block "renesas,r8a7795-cpg-mssr" +11:14 < geertu> Do you have a better suggestion? +11:14 < dammsan> geertu: i'm ok with that, but i would simply go with "r8a7795-cpg" +11:14 < geertu> (the old bindings for CPG only use e.g. ""renesas,r8a7790-cpg-clocks", and +11:14 < dammsan> and keep the mssr abstraction in C +11:14 < mturquette> I'm fine with either compat string name. Hopefully future chips will call the IP block something like Clock And Reset (CAR) or Reset and Clock Manager (RCM) or something :-) +11:14 < geertu> "renesas,rcar-gen2-cpg-clocks" +11:15 < dammsan> so our only concern at this point is the compat string? =) +11:15 < mturquette> I did have one other quick question +11:15 < mturquette> Do you plan to introduce reset framework bits into drivers/clk/shmobile/ ? +11:15 < geertu> If the technical side is OK, we can start bikeshedding +11:15 < geertu> mturquette: Yes, that's the plan +11:15 < mturquette> geertu: OK, great. +11:16 < geertu> tegra does it that way, too, IIRC +11:16 < mturquette> geertu: for the binding I'm very happy with it. +11:16 < geertu> I'm running the code here on r8a7795 and r8a7791, so that part works, too. +11:16 < mturquette> geertu: I don't have any review comments for the driver implementation at this time, so I'll post them later today on the list if I have anything, otherwise I can merge the series. +11:16 < dammsan> good! +11:16 < geertu> For the resets, it's still to be seen how good that works, and how it is to be used +11:17 < mturquette> geertu: or, do you plan to package things up in a PR? +11:17 < geertu> (resets have to be used explicitly by each individual driver?) +11:18 < dammsan> if everyone is happy - when can we see it in -next? +11:18 < dammsan> (i mainly care about the binding) +11:18 < geertu> Does anyone have any comment w.r.t. #defining all clocks in include/dt-bindings/clock/r8a7795-cpg-mssr.h upfront, or only having the ones we curently need? +11:19 < dammsan> geertu: as long as error handling is sane anything is fine with me +11:19 < dammsan> (running new DTB on old kernel) +11:20 < geertu> dammsan: new DTB on old kernel won't work +11:20 < geertu> dammsan: old DTB on new kernel should work if you include the old driver +11:20 < dammsan> geertu: but when you add clocks you increase support level in the driver, right? +11:21 < geertu> dammsan: another question is how complex we want the logic in drivers/sh/pm_runtime.c for the legacy clock domain to be +11:21 < mturquette> RE: defining all clocks, I'm of course fine with that, but the header is part of the "stable" binding. +11:21 < geertu> dammsan: yes, the cpg-mssr driver so far only implements the clocks we use +11:21 < mturquette> geertu: so it might be a safer approach to only add clocks as you need them. removing clocks breaks backwards compatibility. +11:21 < geertu> mturquette: of course. So it's append only. +11:21 < mturquette> geertu: but the choice is yours. i'm fine either way. +11:22 < dammsan> geertu: so say you add clocks to upstream +11:22 < dammsan> geertu: and people use the latest DTB with an old kernel +11:22 < dammsan> geertu: then the new clocks should fail to register, but shall the system halt? +11:23 < dammsan> geertu: in my mind it makes sense to keep the system working +11:23 < geertu> mturquette: My main thinking there is to switch over Gen2 (so far there's a single SoC in Gen3 only): do we (try to) keep numbers in sync between different SoCs of the same family? Syncing means we will have gaps in the numbering, but it may make the C code simpler. +11:23 < mturquette> geertu: i don't see why keeping the numbers the same is important +11:24 < mturquette> geertu: you're using preprocessor macros/defines for the numbers, right? +11:24 < mturquette> geertu: the symbols are the only thing that need to be sync'd between Linux kernel and the binding +11:24 < geertu> dammsan: It will print an error message that it can't handle the clock (cfr. the "default" switch case) +11:24 < dammsan> geertu: thats fine if the rest of the system works +11:24 < geertu> mturquette: For the CPG core clock outputs we use #defines. +11:25 < geertu> dammsan: and it will continue +11:25 < dammsan> geertu: wondershon +11:25 < geertu> mturquette: For the module clocks (and future resets) we use hardcoded numbers +11:25 < geertu> as these match the datasheet +11:26 < geertu> The CPG core clock numbers are numbers we come up with ourselves. +11:26 < mturquette> geertu: OK. the only problem there is if you have a NR_CLKS or NR_RESETS value that changes as new entries are added. +11:26 < dammsan> geertu: those hard coded numbers match the documentation 100%, right? +11:26 < geertu> dammsan: yes, they're the old "MSTP numbers" +11:27 < geertu> mturquette: NR_CLOCKS is only in the driver (C code) +11:27 < dammsan> geertu: right, and they are kind of sparsely populated I think +11:27 < mturquette> geertu: sounds good to me. +11:27 < geertu> mturquette: About numbering for different SoCs +11:27 < mturquette> geertu: i prefer a non-sparse list for "fake" numbers, but of course it makes sense to use a sparse list if you are matching the hardware. +11:28 < geertu> E.g. r8a7790 has more CPG core clocks than r8a7791. +11:28 < geertu> But both have QSPI. So R8A7790_CLK_QSPI may be different from R8A7791_CLK_QSPI +11:29 < geertu> Currently I use the CLK_TYPE_GEN2_QSPI clock type (internal to the C driver) to handle that. +11:30 < dammsan> geertu: on gen2 with mssr, will you use a generic compat string, or break out per SoC? +11:30 < mturquette> Hmm, I'll take a look at that. +11:30 < geertu> dammsan: yes, module clocks are sparsely populated. and more may show up or disappear with a revision of the datasheet :-) +11:30 < mturquette> On other implementations I see typically a big list of clocks in the driver which are common. And then various other smaller lists which break out the SoC-specific bits. +11:31 < dammsan> geertu: right. so matching the data sheet directly makes sense +11:31 < geertu> dammsan: per SoC, as the core clock registers are different (mainly about existence vs. non-existence) +11:31 < dammsan> geertu: sounds ggggggggood +11:32 < dammsan> mturquette: this is how to split the common code and soc-specific in C, right? +11:32 < dammsan> or does it affect the DT ABI? +11:32 < mturquette> dammsan: correct. It prevents from having to register two qspi clocks by accident +11:32 < dammsan> makes sense +11:32 < mturquette> dammsan: and thus it does not matter if the DT binding uses the same number for the qspi clocks on different SoCs +11:33 < dammsan> mturquette: so you have one name space per SoC? +11:33 < mturquette> and since you are using per-SoC compat strings, its easy to match on this +11:33 < mturquette> dammsan: right. +11:33 < dammsan> the numbers may or may not be shared +11:33 < geertu> On problem is we don't know in advance which clocks are common and which are SoC-specific (or become SoC-specific once a new derived SoC is released which lacks a hardware block) +11:33 < dammsan> between SoCs +11:33 < mturquette> but, generally you can describe 90% of your clocks in one big array which are shared by all the SoCs in the same family +11:34 < mturquette> and even if a new SoC comes out and changes this, you don't break DT compat, since its just an internal driver change to migrate a clock out of the "common" array into soc-specific arrays +11:34 < mturquette> geertu: ^^^ I think the point above addresses that. +11:34 < dammsan> mturquette: sure, sounds good +11:35 < mturquette> as long as the shuffling happens in the C driver and doesn't break compat, then its fine. +11:35 < mturquette> new kernels with different tables of per-soc clocks should still work with old DTBs +11:35 < geertu> So having the (intermediate) CLK_TYPE_GEN2_* defines is good, as it allows to isolate different SoCs +11:36 < geertu> And the SoC-specific numbers can be contiguous +11:36 < dammsan> mturquette: so you dont care how the DT ABI numbers are allocated? +11:36 < dammsan> as long as they are kept working +11:36 < dammsan> ? +11:37 < geertu> dammsan: Mike said before he prefers a non-sparse list +11:37 < dammsan> geertu: ok thanks, sorry for being slow +11:37 < mturquette> geertu: dammsan: I won't NAK a patch based on the list type. its really your choice. +11:38 < mturquette> geertu: I searched for CLK_TYPE_GEN2 in the v4 series and I don't see it? +11:38 < dammsan> so the current gen2 approach, is it good or bad? +11:38 < dammsan> (i mean the old upstream way with separate CPG and MSTP) +11:39 < dammsan> (the CPG clocks are virtual and non-sparse) +11:39 < geertu> mturquette: I didn't post the Gen2 driver, only the Gen3 one +11:39 < mturquette> geertu: ah, I see. Thanks. +11:39 < geertu> so you want to look for CLK_TYPE_GEN3\ +11:40 < geertu> For Gen3 we support a single SoC only +11:40 < geertu> I mainly did the Gen2 version (for r8a7791 only) to validate the approach, as we have more hardware support there +11:41 < geertu> To support SoC-family and SoC-specific tables, I just need to split cpg_mssr_info.core_clks[] into two arrays +11:41 < mturquette> geertu: I see. Thanks. +11:42 < geertu> and call the SoC-family cpg_clk_register() from the SoC-specific .cpg_clk_register() callback +11:42 < mturquette> geertu: using an enum/flag or splitting it per-clock/per-soc tables, either way is fine with me. +11:42 < dammsan> geertu: i think your code looks clean and easy to read +11:42 < mturquette> ack. +11:43 < mturquette> and it looks like the array of clock data follows the hierarchy? that's always nice. +11:43 < mturquette> (at least for cpg) +11:43 < geertu> mturquette: yes, each entry has a parent clock +11:43 < geertu> (div6 clocks with multiple parents are not yet supported) +11:44 < geertu> (but support can be added, of course) +11:44 < dammsan> geertu: it looks like your V4 series is based on the old Gen3 driver? +11:44 < dammsan> clk-rcar-gen3.o +11:45 < dammsan> i mean the code base includes the old driver, but it is not used +11:46 < dammsan> or am i misunderstanding? +11:47 < geertu> dammsan: you mean in renesas-drivers.git? +11:48 < dammsan> i suppose you simply based your tree on the old implementation +11:48 < geertu> yes +11:48 < dammsan> i mean the V4 series +11:48 < dammsan> The [5/5] Makefile hunk gives you away =) +11:49 < geertu> one moment please, there's a delivery here... +11:53 < dammsan> mturquette: so on your side, with the DT binding, when do you think it can end up in -next? +11:53 < dammsan> (we tend to treat it as semi-stable once it hits -next) +11:53 < dammsan> maybe semifreddo is a better word =) +11:55 < mturquette> geertu: are you planning to send a PR? +11:55 < mturquette> dammsan: I have answered your question with a question. +11:59 < dammsan> mturquette: a question to me, or to geertu? =) +11:59 < dammsan> (i can't seem to locate the answer/question in my history) +12:00 < geertu> mturquette: it's just patches 1 and 2 of the series, right? +12:01 < geertu> Is it worth sending a pull request for that? +12:01 < mturquette> geertu: I'm confused. I will finish reviewing all 5 patches later today. I can either merge them directly (if there are no problems) or you can send me a PR with any other outstanding renesas clk patches. +12:02 < mturquette> geertu: but I'm confused by your comment about "just patches 1 and 2" +12:02 < geertu> mturquette: bindings are patches 1 (binding doc) and 2 (clock defines) +12:02 < dammsan> geertu: do you feel the driver bits need more time to stabilize before merging upstream? +12:02 < geertu> mturquette: 3-5 are implementation, which can use some review and need a bit of rework +12:03 < geertu> dammsan: there are FIXMEs and too many debug prints +12:03 < mturquette> geertu: Then lets keep all 5 together. No reason to merge "dead code" +12:03 < dammsan> geertu: ok, no problem +12:03 < geertu> Does that mean we postpone everything to v4.5? +12:04 < geertu> I thought the plan was to get the bindings accepted in v4.4 +12:04 < geertu> so we know what we're working against (binding-wise) for v4.5 +12:04 < dammsan> that would be very nice yes +12:04 < mturquette> geertu: that's fine, i can merge them if you would like. +12:05 < dammsan> so a separate PR with patch 1 + 2? +12:05 < mturquette> geertu: but once a Linux release is made they considered somewhat stable +12:05 < mturquette> No PR necessary. I was only asking if geertu planned to send a PR already. +12:05 < dammsan> ok sweet +12:06 < geertu> yes, thx +12:06 < dammsan> geertu: so i looked through patch 1 + 2 +12:06 < mturquette> (I prefer PRs because I invariably miss something when it is left up to me to pick patches ;-) +12:06 < dammsan> and they look good +12:06 < geertu> Has anyone reviewed include/dt-bindings/clock/r8a7795-cpg-mssr.h? +12:06 < dammsan> geertu: do you need anything from me? +12:06 < geertu> OK, will send a PR later today +12:06 < geertu> for patches 1 and 2 +12:07 < geertu> dammsan: Reviewed-by? +12:07 < dammsan> sure, i will go through once more tonight and reply to public space +12:07 < mturquette> geertu: feel free to add my Ack to both patches +12:08 < geertu> The defines are based on Table 8.2a +12:08 < geertu> ("List of Clocks [R-Car H3]") +12:08 < dammsan> thanks, will check +12:09 < dammsan> will get back to you later tonight JST +12:10 < geertu> mturquette: ok, thx +12:13 < geertu> BTW, the bindings mention r8a7791 too. I guess I better leave that out for now. +12:16 < geertu> Any other clock related topics? +12:16 < mturquette> geertu: None from me. +12:16 < geertu> OK, next topic +12:16 < geertu> 1.

+10:12 < horms> yes, i think so +10:12 <@wsa_> knock on wood :) +10:12 < horms> I think the main questin will be if the binding needs changing. to my mind the answer is "hopefully not" +10:13 < horms> in theory other clocks could be relevant +10:13 < horms> but in practice the hw only accepts using the high-speed peripheral clock (or what that was renamed to in gen3) +10:13 < horms> so fingers crossed it should not be too difficult to resolve in an upstreamable manner +10:14 * wsa_ crosses fingers +10:14 <@wsa_> thanks simon +10:14 <@wsa_> about PCIE +10:14 <@wsa_> I tested Phil's patches, and they turned out to go into the right directon, but being unusable for now +10:15 <@wsa_> even introducing a build error +10:15 < horms> :( +10:15 <@wsa_> Bjorn wants to drop the branch which would also be my favourite solution +10:16 < horms> thats fine by me.

The Core group developer is expected to +10:07 < geertu> collaborate with group members on a best effort basis to develop and upstream +10:07 < geertu> Linux kernel modifications for frameworks, device drivers and SoC specific +10:07 < geertu> code. The Core group developer is asked to work with the group leader to +10:07 < geertu> iterate on yet-to-be-implemented feature lists as well as reference +10:07 < geertu> implementations. Hardware devices and areas expected to be covered by the Core +10:07 < geertu> group are: +10:07 < geertu> \begin{enumerate} \item ARM CPU clusters including SMP, caches and CCI / AXI \item Power control, clocks and reset such as APMU, SYSC, CPG, MSTP, RST \item Interrupts including GIC and IRQC and Timers \item Debugging hardware such as ARM core sight \item DMA controllers and IOMMU devices \item Pincontrol PFC and GPIO +10:07 < geertu> \end{enumerate} +10:07 < geertu> The group may select target platforms for reference implementations freely from +10:07 < geertu> the range of available boards with upstream support from Renesas. In case of +10:07 < geertu> R-Car Gen3 it may be necessary to use FPGA based target platforms.

Card detection pins? +10:50 < dammsan> by reading out data structure from the SD card +10:50 < dammsan> it is sort of like PCMCIA or any other bus +10:50 < horms> does it read the structure using v1.8? +10:50 < dammsan> the MMC subsystem and the driver ramp up the speed and decrease voltage during detection +10:51 < geertu> So you can't just measure the pins without a card +10:51 < dammsan> i don't know the details except that it varies based on capability of each card +10:51 < dammsan> well you can write a mock-up that somehow controls the PFC +10:51 < dammsan> and then verify the pin output or something +10:52 < dammsan> but PFC support without driver is not very useful anyway +10:52 < pinchartl> dammsan: no but PFC is a dependency for the driver +10:52 < dammsan> well, SDHI is not any different from any otehr driver +10:52 < dammsan> exept it has some more advanced PFC toggling to do +10:53 < dammsan> it all ties to the driver IMO +10:53 < dammsan> or how would you guys do it? +10:54 < dammsan> PFC tick-box? =) +10:54 < pinchartl> I'd implement it on the PFC side and test it using a scope or multimeter +10:54 < pinchartl> and then implement it on the SDHI side +10:55 < dammsan> in the non-existing driver? =) +10:55 < dammsan> or part of upstreaming process i guess +10:55 < dammsan> SDHI on Gen3 has on-device DMAC engine +10:55 < dammsan> different from Gen2 +10:56 < uli___> horms: https://www.sdcard.org/downloads/pls/part1_410.pdf, page 17 +10:56 < dammsan> Gen2 did not get UHS-I and UHS-II working upstream +10:56 < dammsan> we are way behind +10:56 < pinchartl> dammsan: frankly I don't see where the problem is.

=) +10:41 < dammsan> what is the opinion? +10:41 < horms> I was hoping for feedback from you +10:41 < dammsan> i see +10:42 < horms> my opinion is, as yours, that we should be careful +10:42 < dammsan> i've been overfocusin on IPMMU due to sudden customer demand... +10:42 < dammsan> and i think i shared some "long term" plan for our upstream development +10:42 < horms> but that we should communicate our plan/concerns to dirk +10:42 < dammsan> and SMP is not happening until next year +10:42 < horms> i did queue up the CA57 patches +10:43 < horms> i can (quickly) drop them for v4.5 if needed +10:43 < dammsan> i don't see any reason to rush +10:43 < dammsan> i think we need a plan =) +10:43 < dammsan> thanks for queuing up things btw +10:43 < horms> i was planning to queue up the CA53 patches for v4.6 unless there was some feedback +10:43 < horms> so i also agree that there is no rush +10:43 < horms> but o think we need to communicate a bit with dirk +10:44 < horms> possibly refocussing his energy elewhere +10:44 < dammsan> i would like to ask someone to check SMP and big.little +10:44 < geertu> dammsan: Do you know a simple test to check if the scheduler is aware? +10:45 < dammsan> geertu: no turn-key, but say spawning off twice the number of benchmark jobs as number of cpus, and see how it behaves? +10:45 < dammsan> if you run with two cores - one big and one little, and spawn off one benchmark job, if it gets stuck on the little one you are screwed +10:46 < dammsan> busy tasks should migrate to the faster cores +10:46 < horms> because it will be slow? +10:46 < geertu> ok, will try something +10:46 < dammsan> yes, and the other big core will be fast and idle +10:46 < horms> ok +10:46 < horms> so how about someone (e.g. me) communicates this with dirk +10:47 < dammsan> that's of course fine with me +10:47 < dammsan> but i think we still need a plan +10:47 < horms> we can deffer his patches until we get a better idea of what their implicatinos are +10:47 < geertu> horms: Please let me try it first +10:47 < horms> geertu: sure, no problem +10:47 < horms> I'm also quite ok with you responding to him +10:47 < dammsan> so one idea can be to get SMP support working as first step +10:48 < dammsan> on big cores +10:48 < horms> isn't that what we now have? +10:48 < dammsan> in a perfect world +10:48 < dammsan> but there are dependencies on timers +10:48 < dammsan> on firware +10:48 < dammsan> cpu hotplug +10:48 < dammsan> kexec +10:48 < dammsan> kernel command line parameters +10:48 < dammsan> ... +10:49 < dammsan> i highly doubt that everything is working +10:49 < dammsan> unless it is a x86 system +10:49 < horms> ok +10:49 < horms> so perhaps we partially have it +10:49 < dammsan> more testing is needed for sure +10:49 < dammsan> either merge (like you did) or topic branch +10:49 < dammsan> and then combine with some testing +10:50 < horms> the point is the merge is done +10:50 < dammsan> right +10:50 < horms> and we have a small window to change our mind +10:50 < dammsan> twhat is your opinion? +10:50 < horms> of course we can revert later +10:51 < dammsan> if you are ok with depending more on teh boot loader stack then i'm fine +10:51 < geertu> How do we know which boot loader stack we have? +10:51 < dammsan> good question +10:51 < geertu> horms: You said you saw one CPU only? +10:51 < dammsan> i kept my various versions in different directories +10:51 < horms> yes i did +10:51 < geertu> I was using my own tree, with my own config +10:51 < dammsan> but lately they seem to be aligned to yocto releases inside renesas +10:51 < horms> but i was using devel + cpg+mssr, not renesas-drivers +10:52 < dammsan> i think we should use the same boot loader stack ideally +10:52 < dammsan> so we may need to coordinate that as well +10:52 < dammsan> so what is a good plan i wonder...? +10:53 < dammsan> I think we should do a joint effort to update our boards after new year +10:53 < horms> is the implication that geert and I may be using different boot loaders? +10:54 < dammsan> i've used 3 different versions +10:54 < dammsan> one worked with IPMMU +10:54 < dammsan> i have not yet used SMP +10:54 < geertu> horms: that's what I'm wondering about, too +10:54 < horms> about the merge, i'm inclined to leave it unless we feel it will be harmful e.g. in terms of updates, in future +10:54 < horms> but i am happy to be convinced otherwise +10:55 < dammsan> horms: i think it is fine to include it if "maxcpus=1" works as on other architectures +10:55 < dammsan> so we have a simple way to boot with a single CPU only +10:55 < dammsan> if we end up with random crashes +10:55 < dammsan> on certain boards +10:56 < dammsan> or we can merge it regardless +10:56 < dammsan> if you are willing to deal with the potential trouble... +10:56 < dammsan> its up to you really +10:56 < dammsan> geert? +10:56 < geertu> I'd be surprised if "maxcpus=1" wouldn't work, but let's try +10:56 < dammsan> do you have any idea how to order SMP + cache + DMAC +10:56 < geertu> cache first +10:57 < geertu> (needed for SYSC PM Domains too) +10:57 < dammsan> ok, lets do that +10:57 < horms> geertu: could you try; i only see one CPU regardless +10:57 < geertu> which brings us to +10:57 < geertu> Topic 3. Cache enablement on Gen3 +10:57 < geertu> The cache is enabled automatically, I think +10:58 < dammsan> i listed it because it ties in with both the DMAC and the CPUs +10:58 < dammsan> apparently the IPMMU has some cache coherent support for page tables +10:58 < geertu> Presence in DT is just dressing up (ARM core viewpoint?), or hard requirement for SYSC PM Domains +10:58 < dammsan> otherwise the other devices require cache management by the CPU +10:59 < geertu> I don't follow that part +10:59 < geertu> There's already cache managment without an IPMMU? +10:59 < dammsan> each bus master device on the system +10:59 < dammsan> well +10:59 < dammsan> i mean, if we use say SYS-DMAC without IPMMU +11:00 < dammsan> we still need to manage the cache since the SYS-DMAC is behind the caches +11:00 < dammsan> that is true for most bus master devices +11:00 < dammsan> the only exception that i am aware of is the IPMMU page tables, but i think there is an errata =) +11:01 < dammsan> so my point is that there is a per-bus-master device coherent/non-coherent view +11:01 < dammsan> and maybe gray zone with different inner sharable / outer sharable domains +11:02 < dammsan> i think the only sane way to handle things for now is to assume that all devices are non-coherent +11:02 < dammsan> and opt-in if needed +11:03 < dammsan> geertu: about the PM domain and caches, why do you need the DT binding? +11:03 < dammsan> to restore state? +11:04 < geertu> dammsan: I don't need a binding, just a power-domains property pointing to the SYSC PM Domain +11:04 < dammsan> ok! +11:04 < dammsan> so caches first? +11:05 < dammsan> in the same way as SMP needs testing, I think we want some benchmarking with/without caches +11:05 < geertu> cfr. http://lists.infradead.org/pipermail/linux-arm-kernel/2015-June/348750.html +11:05 < geertu> Aren't the caches automatically enabled? +11:06 < dammsan> neat! +11:07 < dammsan> it depends on boot loader version +11:07 < dammsan> but i guess it should +11:07 < dammsan> for Gen2 we need to handle caches when doing CPU hotplug +11:07 < geertu> For gen3, we have arm,psci +11:07 < dammsan> on Gen3 i guess the PSCI bits do something magic for us +11:08 < dammsan> geertu: so your plan is to enable caches first? +11:09 < dammsan> or somehow hook them in according to your patch +11:09 < geertu> Without the caches in DT, my debug prints on Salvator-X still print +11:09 < dammsan> above +11:09 < geertu> L1-D: CCSIDR = 0x701fe00a: 32 KiB, 256 sets, 2 ways, 64 bytes/line, WB, RA, WA +11:09 < geertu> L1-I: CCSIDR = 0x201fe012: 48 KiB, 256 sets, 3 ways, 64 bytes/line, RA +11:09 < geertu> L2-U: CCSIDR = 0x70ffe07a: 2048 KiB, 2048 sets, 16 ways, 64 bytes/line, WB, RA, WA +11:09 < dammsan> i see +11:09 < dammsan> i don't recall if we are able to disable caches in the Kconfig for ARM64 +11:10 < geertu> and +11:10 < geertu> Detected PIPT I-cache on CPU0 +11:10 < geertu> Detected PIPT I-cache on CPU1 +11:10 < geertu> CPU1: Booted secondary processor [411fd073] +11:10 < geertu> Detected PIPT I-cache on CPU2 +11:10 < geertu> CPU2: Booted secondary processor [411fd073] +11:10 < geertu> Detected PIPT I-cache on CPU3 +11:10 < geertu> CPU3: Booted secondary processor [411fd073] +11:10 < geertu> Brought up 4 CPUs +11:10 < geertu> SMP: Total of 4 processors activated. +11:10 < geertu> CPU: All CPU(s) started at EL1 +11:10 < geertu> but +11:10 < geertu> Unable to detect cache hierarchy from DT for CPU 0 +11:11 < dammsan> hm +11:11 < dammsan> i wonder what juno says +11:11 < geertu> I'll run my memory speed benchmark... +11:13 * geertu notices that "maxcpus=1" works as expected +11:13 < horms> geertu: thanks! +11:13 < dammsan> yeah, thank you! +11:13 < horms> lets leave those patches in and revert them if the wheels fall off +11:14 < geertu> ok +11:14 < dammsan> horms: but wait with ca53? +11:14 < horms> yes +11:14 < horms> i have no plan to add them to v4.5 +11:15 < horms> and i will wait for some testing before considering them for v4.6 +11:15 < horms> of course our plan will evolve... +11:15 < horms> (or die!) +11:15 < dammsan> goooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooosounds good - thanks! +11:16 < dammsan> (darn my VM environment gets key stuck sometimes) +11:16 < horms> it got stuck in a goood place! +11:16 < dammsan> indeeed +11:17 < horms> btw, i am hoping to finish up at 19:30 +11:17 < dammsan> so what do we do about firmware update? +11:17 < dammsan> any idea? +11:18 < dammsan> horms: i want to discuss the DMAC framework bits too, but you may not care so much +11:18 < horms> well, presumably there is a procedure. perhaps morimoto-san can get us the new images etc... +11:18 < horms> dammsan: perhaps i can go away and come back +11:18 < horms> i only plan to give my son a bath +11:19 < dammsan> anything is fine with me really +11:19 < horms> ok +11:19 * geertu notices his MemSpeed test (which read/writes/copies increasing blocks of memory) shows no difference between L2 cache nodes present in DT or not +11:20 < dammsan> how much memory do you have on your system geert?

+10:28 < geertu> I want to look into SYSC PM Domains and integrate it with your DT CPU bringup series +10:28 < dammsan> cool +10:29 < dammsan> when i hear PM i am also thinking of making sure Suspend-to-RAM works +10:29 < dammsan> ideally i wanted to get that going before enabling SMP +10:29 < geertu> SMP is already enabled ;-) +10:30 < geertu> And I want to fix suspend with CONFIG_DEBUG_RODATA=y +10:30 < dammsan> yeah, so now we need to consider SMP as well +10:30 < dammsan> which drags in the boot loader dependency +10:30 < dammsan> geertu: we were talking about SCIF hardening with DMAC +10:31 < dammsan> part of DMAC enablement i guess +10:31 < geertu> "ARM: mm: flip priority of CONFIG_DEBUG_RODATA" revealed a big in the shmobile asm suspend code. The patch was reverted, but will come back in next merge window +10:31 < geertu> Yeah, another thing I plan to do +10:32 < geertu> s/big/bug/ +10:32 < dammsan> geertu: may i ask about ordering +10:32 < dammsan> with SYS-DMAC enablement and also PM +10:32 < geertu> Sure +10:32 < geertu> What's your preferred order? +10:32 < dammsan> does it make sense to enable some initial support before updating the boot loader? +10:33 < dammsan> geertu: did SMP work for you or not - i don't remember +10:33 < geertu> Yes, SMP works (all 8 cores) +10:33 < geertu> If it doesn't work, try SW10 +10:33 < dammsan> good! +10:33 < dammsan> i've spent quite some time with SW10 updating boot loaders thanks =) +10:34 < dammsan> so i guess enabling DMAC is a rather good activity +10:34 < dammsan> doing that this month, does that make sense? +10:35 < geertu> Sure +10:35 < dammsan> and later on roll in IPMMU +10:35 < dammsan> how about the PM bits +10:35 < dammsan> doing Suspend-to-RAM before or after or parallel? +10:36 < dammsan> i think the timer needs some work too +10:36 < geertu> after / parallel (if the other becomes blocked)? +10:37 < dammsan> sounds good +10:37 < dammsan> it would be neat to get kexec working too +10:37 < geertu> Is it working now on arm64 in general? +10:37 < dammsan> i would assume no +10:38 < dammsan> so geertu: for SCIF hardening and DMAC enablement, what is needed apart from DTS? +10:39 < dammsan> i saw your recent BRG patches, shall Mbps setting over loopback work? +10:39 < geertu> It should +10:40 < dammsan> great!! +10:40 < geertu> dammsan: Fixing the hardware (perhaps)? +10:40 < dammsan> obviously with b0rk timer nothing works well +10:41 < dammsan> geertu: what pending issue are you thinking of? +10:41 < geertu> last time I tried, RX SCIF DMA didn't work at all +10:41 < geertu> (Yes, I have to retry) +10:41 < geertu> on r8a7795 +10:42 < dammsan> geertu: maybe we can revisit after data sheet update and boot loader update +10:42 < dammsan> how about other people? +10:43 < dammsan> pinchartl: you were proposing to conver the IOMMU driver to be more modern for ARM32? =) +10:43 < geertu> dammsan: Speaking about datasheet update, I have to look into the recent errata for CPG +10:43 < pinchartl> dammsan: yes +10:44 < dammsan> geertu: yeah, errata.. also we were talking about keeping the GPIO MSTP bit enabled +10:44 < pinchartl> if we want to use the same IOMMU driver on ARM32 and ARM64 we'll need that +10:45 < dammsan> pinchartl: i was hoping that you could work with neg for the framework bit for IPMMU + DMAC +10:45 < pinchartl> do you mean guiding Niklas or writing the code myself ? :-) +10:45 < dammsan> pinchartl: i was never opposed to that change, but i did not want to block r8a7795 prototype support on that +10:46 < dammsan> pinchartl: how about you work together and figure out the details by yourself? =) +10:46 < pinchartl> I won't have time to do the work in January, but I can guide Niklas +10:46 < dammsan> geertu: what do we have on the todo list that need attention from pinchartl? +10:47 < dammsan> i want renesas-drivers to have working DU VGA-out on Salvator-X +10:47 < dammsan> so i can poke around with IPMMU on top of that +10:48 < pinchartl> that is on my to-do list +10:48 < geertu> dammsan: pinctrl documentation acked-by ;-) +10:48 < dammsan> pinchartl: guiding neg sounds good +10:48 < pinchartl> speaking of DU VGA out +10:48 < pinchartl> that involves the VSP1 +10:48 < pinchartl> and thus V4L2 +10:48 < geertu> dammsan: a patch fixing the vsp1 BUG() with media-next? +10:48 < pinchartl> I'm not in best terms with the V4L2 maintainer at the moment +10:48 < pinchartl> which could introduce delays in getting patches upstream +10:49 < pinchartl> geertu: that's an open issue +10:49 < pinchartl> media-next is broken +10:49 < dammsan> pinchartl: thats fine +10:49 < pinchartl> and if it comes to the worst I'll nack the pull request to Linus +10:49 -!- shimoda [~shimoda@relprex1.renesas.com] has joined #periperi +10:49 < geertu> shimoda-san: Welcome back! +10:50 < dammsan> pinchartl: we need to have something working for use by ourselves and the BSP team +10:50 < pinchartl> dammsan: internally or upstream ? +10:50 < dammsan> in renesas-drivers to begin with +10:50 < dammsan> upstream too, but i understand it may be difficult to control that timing +10:50 < pinchartl> it's very difficult at the moment +10:50 < geertu> Does vsp1 work with current renesas-drivers (i.e. excl. current media-next)? +10:51 < pinchartl> it should but I haven't updated renesas-drivers for about a month +10:51 < pinchartl> I'll test it +10:51 < dammsan> gpinchartl: please do =) +10:51 < pinchartl> for upstream I'm not sure what I can do +10:52 < pinchartl> neither now nor in the future +10:52 < dammsan> please guide morimoto with HDMI audio +10:52 < pinchartl> HDMI audio on Gen3 ? +10:52 < shimoda> geertu: hi :) +10:52 < dammsan> gen2 to begin with +10:52 < pinchartl> that should be fine +10:53 < pinchartl> but isn't this a core meeting, not a multimedia meeting ? :-) +10:53 < dammsan> aright +10:53 < pinchartl> I'm fine discussing multimedia +10:53 < pinchartl> but we have a multimedia meeting tomorrow +10:53 < pinchartl> I don't want to hijack today's meeting +10:53 < dammsan> yes lets do that then +10:53 < dammsan> but i need to make sure we can consume your stuff +10:53 < dammsan> and it goes through geerts tree +10:54 < dammsan> DU+VSP is starting to become a bottleneck +10:54 < dammsan> thanks for looking into that +10:54 < pinchartl> I'll make sure it works with renesas-drivers excluding media-next +10:54 < geertu> git rerere is my friend +10:54 < dammsan> please work with geert to sort it out +10:54 < pinchartl> but for upstream I have no idea how things will turn out +10:54 < pinchartl> if I nack the media-next pull request my ability to get anything merged in media will be diminished +10:54 < dammsan> pinchartl: please talk with hayama-san about that too +10:55 < geertu> For now I can keep excluding media-next, but as soon as Linus has pulled it, we're in trouble +10:55 < pinchartl> if I don't nack it, all kind of crap will end up in mainline +10:55 < geertu> Good, Linus doesn't like crap +10:56 < pinchartl> Linus knows about this already, I know that Mauro has personally contacted him to complain about me +10:56 < pinchartl> I don't know what the outcome of their discussion was though +10:56 < geertu> oops +10:58 < dammsan> regarding upstream merge, i guess we're waiting for the CPG and integration code to hit mainline? +10:58 < pinchartl> upstream merge of what ? +10:58 < geertu> They're in next +10:58 < dammsan> yeah +10:58 < dammsan> a lot of integration code is built but not yet merged upstream +10:59 < dammsan> not sure if any V4L2 explosion will affect ARM64 merge?

It is OK ? +09:50 < wsa_> sounds good to me +09:50 < morimoto> Cool +09:52 < wsa_> okay, then, happy hacking, I'll be off +09:52 < wsa_> cya +--- Log closed Fri Jan 08 09:52:09 2016 diff --git a/wiki/Chat_log/20160119-core-chatlog b/wiki/Chat_log/20160119-core-chatlog new file mode 100644 index 0000000..4bd50be --- /dev/null +++ b/wiki/Chat_log/20160119-core-chatlog @@ -0,0 +1,341 @@ +Core-chat-meeting-2016-01-19 + +10:08 < geertu> Agenda: +10:08 < geertu> 1.

The latest should now be renesas-devel-20160118-v4.4 +10:21 < dammsan> yeah, and requesting errata information from renesas if needed +10:21 < dammsan> we also have CAE/CAIR error management for the rcar-dmac.c driver +10:22 < dammsan> so it seems that the driver itself needs some attention at some point +10:22 < geertu> I don't think there was anything SYS-DMAC related in the Gen3 errata we received through Jinzai +10:22 < geertu> horms: got it +10:22 < neg> I know about one of the errat fixes in dmac.c about not using the first channel I can lookinto if that is needed on gen3 and if not try to fix it +10:23 < dammsan> neg: thanks for stepping up +10:24 < morimoto> dammsan: please let me know if you want to ask it to datasheet guys +10:24 < geertu> The first channel issue is only with IPMMU enabled, right? +10:24 < dammsan> i believe so +10:25 < dammsan> morimoto: thanks +10:26 < geertu> I've retried SYS-DMAC on Salvator-X with (H)SCIF, and RX DMA is working now, too. +10:26 < geertu> Strange, as I believe the board I have now is the same I was using remotely before? +10:26 < dammsan> geertu: thanks, i saw your email +10:26 < dammsan> i think we should revisit after upgrading firmware =) +10:26 < geertu> However, I had mixed results with IPMMU enabled +10:27 < geertu> (ah, now I realzie while the console still worked with IPMMU: SCIF2 is on DMAC1, where IPMMU wasn't enabled) +10:27 < geertu> OK, firmware upgrade it'll be +10:27 < dammsan> i think the current working sample of H3 has some IPMMU hardware issues +10:28 < dammsan> so M3 may be in better state for serious IPMMU usage +10:28 < geertu> OK +10:28 < geertu> Anyway, SYS-DMAC is now declared "working" +10:28 < geertu> Moving on to PM... +10:29 < neg> from rcar-dmac.c 'A still unconfirmed hardware bug prevents the IPMMU microTLB 0 to be flushed correctly, resulting in memory corruption.' can we confirm the HW bug somehow? +10:29 < dammsan> neg: that is on gen2 and we could not get information earlier +10:30 < neg> ok I see if I can give it a try on gen3 +10:30 < dammsan> neg: please focus on the framework bits since the hardware itself may be unstable +10:31 < neg> ok +10:31 < dammsan> geertu: regarding PM, is SYS-DMAC working with PM as well? =) +10:32 < dammsan> it used to be a can of worms +10:32 < geertu> dammsan: I think so, at least on Koelsch +10:33 < geertu> Yeah, we had a few PM-related crashes during its development in Summer 2014 +10:33 < dammsan> good! +10:35 < dammsan> is core handling thermal sensor? +10:35 < dammsan> i don't remember +10:35 < geertu> git grep -i therm +10:35 < geertu> io/todo +10:36 < dammsan> if so i would like someone to lookin some errors +10:36 < dammsan> ok i see +10:37 < geertu> Anything else to report for Topic 1? +10:38 < horms> one small thing from the upport world +10:39 < horms> Kaneko-san says the PWM upport is a bit tricky for him. I'll see about handling it myself else report back here or the periperi ML. +10:39 < horms> end +10:40 < shimoda> oh, original pwm driver is made by me +10:40 < shimoda> so, I'll check the bsp patches later +10:41 < horms> his difficulty is with the clocks. i assume because the driver is different in mainline. if you want to handle this feel free to do so :) +10:42 < morimoto> Is this BSP original driver do you mean ? +10:42 < dammsan> geertu: what are you hacking on from now on? +10:43 < horms> I assume the CPG dirvers are different. To be honest I haven't looked at the patches yet +10:43 < morimoto> Ah.. OK thanks +10:43 < dammsan> geertu: i noticed that a bunch of SCIF code went into mainline recently - thanks for that +10:44 < geertu> dammsan: I started SYS-DMAC, but that seems to work now +10:44 < geertu> dammsan: So next will be PM, integrating your CPU bringup for Gen2 with the SYSC PM Domain stuff +10:45 < dammsan> geertu: in your r8a7795 SYS-DMAC DTS patch you wrote you tested MSIOF - may I ask how? +10:45 < dammsan> i could not get MSIOF to work well on Gen3 myself +10:45 < geertu> MSIOF indeed has hardware bugs +10:45 < dammsan> geertu: ok, PM sounds good +10:45 < geertu> But it sends out data when DMA is used +10:46 < dammsan> so _something_ is working =) +10:47 < geertu> Yeah, it behaved the same for PIO and DMA, which IMHO proves that DMA is working ;-) +10:47 < dammsan> equally busted =) +10:48 < dammsan> i'll try to re-verify MSIOF on Gen2 and then revisit Gen3 +10:48 < dammsan> the BSP workaround seems pretty useless +10:49 < dammsan> or rather - i cannot see how it would help MSIOF +10:49 < dammsan> but anyway +10:49 < horms> dammsan: could you verify my sound patches on gose when you have time. They may even work :) +10:49 < shimoda> horms: sorry for the delayed, the commit 2d63d5d9aa6685d028d254ceb877678c0f19363b in renesas-bsp is merged to linux-pwm (72c16a9f98afad073b4a9c947c1c89bfb886ffcb) by me :) +10:49 < geertu> Same for me, haven't tried it yet (on my io todo list) +10:49 < shimoda> so, no need to upport on pwm driver for now +10:50 < dammsan> horms: my gose whines about thermal errors currently +10:50 < horms> oh +10:50 < dammsan> if we could get a loopback test then i'd be happy to connect a cable +10:52 < geertu> dammsan: just compile and run spidev_test.c +10:52 < geertu> In the mean time, SPI got an internal loopback test, but I haven't tried it yet. +10:52 < geertu> Topic 2. Could we change initcall() in some drivers? +10:53 < dammsan> my test case is to use MMC-over-SPI +10:53 < dammsan> but anyway, lets move to topic 2 +10:53 < geertu> The short answer is "always use module_init() (except if ...)" +10:53 < dammsan> this seems to be a per-subsystem thing +10:53 < geertu> There's a global trend to move to module_init() +10:54 < geertu> Excessive deferred-probing is being worked on, cfr. the thread "[RFD] Functional dependencies between device" +10:54 < dammsan> thats nice +10:54 < geertu> Rafael W. posted some initial patches, but they don't derive dependencies from DT yet +10:55 < geertu> For the specific case of renesas-cpg-mssr.c, using a different priority than subsys_initcall() caused issues on r8a7791 +10:55 < dammsan> that must be connected to timer init order somehow +10:56 < geertu> irqc +10:56 < dammsan> ouch +10:56 < geertu> and Ethernet +10:57 < geertu> and R-Car Gen2 regulator quirk (which is actually still a problem, I think) +10:57 < geertu> So yes, it's a mess, and don't touch ;-) +10:57 < geertu> until Rafael will fix it (hopefully) +10:57 < dammsan> hehe +10:58 < dammsan> would it be possible to use cpg-mssr on Gen2 together with MMCIF? +10:58 < dammsan> to provide a reference implementation for the BSP people? +10:58 < dammsan> to get the GPIO regulators and whatnot working as expected +10:59 < geertu> I think so +10:59 < dammsan> geertu: the Gen2 regulator quirk is hopefully not needed on Gen3? +10:59 < geertu> It's board-specific +11:00 < dammsan> i realize it is a board deisng issue +11:01 < dammsan> shimoda: what is the correct way to support the BSP people wrt initcall level? +11:01 < horms> shimoda: thanks, got it +11:01 < geertu> dammsan: You should know, you're doing irqc :-) +11:01 < horms> shimoda: (pwm change) +11:01 < geertu> there are no irqc interrupts shared between devices +11:02 < dammsan> geertu: yes =) +11:03 < dammsan> regarding the initcall discussion, it must make sense to use same levels for upstream and BSP +11:03 < shimoda> dammsan: I sent rcar-gpio things that Morimoto-san mentioned to BSP team +11:03 < dammsan> to avoid cluser fuck +11:03 < shimoda> so, I will wait for their reply for now +11:03 < dammsan> ok thanks! +11:06 < geertu> [advertising: media-next/master has entered mainline, causing a boot crash on koelsch with vsp1 enabled] +11:07 < horms> wtf!!! +11:07 < horms> so it was broken in next for a month +11:07 < horms> known to be broken +11:07 < horms> and then moved to mainline +11:07 < horms> is there more to this story? +11:08 < dammsan> i would be prepared to take that detail if we can get the arm64 bits merged +11:08 < geertu> Not to mention Laurent's "doubts" response to the pull request +11:08 < dammsan> hopefully those are not connected +11:09 < dammsan> horms: what's your plan with CONFIG_RENESAS btw? +11:09 < dammsan> now when the mailing list is sorted i mean +11:09 < horms> geertu: I assume that Laurent is on the case with regards to the media problem. if not perhaps i should speak with him? +11:10 < horms> dammsan: i suppose the symbol is in mainline now/soon so we/I can start updating the drivers. +11:10 < dammsan> sweet +11:10 < horms> is there anything i should focus on there from your pov? +11:10 < dammsan> nah =) +11:10 < dammsan> just curious +11:11 < horms> np. i realised the other day that its about time for some more activity there +11:11 < geertu> horms: Laurent expressed his feelings, cfr. thread "[GIT PULL for v4.5-rc1] media controller next gen patch series" +11:12 < geertu> horms: not much we can do now, I'm afraid. +11:13 < geertu> Either Mauro provides a fix (perhaps after a big rant from Linus), Linus unpulls (unlikely, too many days ago), or nothing happens +11:13 < dammsan> we need a zeroday machine +11:14 < horms> well its more like we have one +11:14 < horms> which is next +11:14 < dammsan> aka smoke machine +11:14 < horms> where this problem showed up weeks ago +11:14 < geertu> I reported the issue more than one month ago +11:15 < horms> well lets hope for a fix +11:15 < horms> its not very good to have one of our main platforms broken in mainline +11:15 < dammsan> very true +11:15 < geertu> You can disable CONFIG_VIDEO_RENESAS_VSP1 +11:15 < dammsan> how about something more recent - how does this affect gen3? +11:16 < horms> geertu: of course. but i suppose customers may want to use vsp... +11:16 < geertu> Hmm, I don't have CONFIG_VIDEO_RENESAS_VSP1 in my Gen3 config yet +11:16 < dammsan> vsp is crucial for DU output on gen3 +11:17 < dammsan> i will have to ask laurent again about current status +11:17 < geertu> Probably broken, too +11:17 < dammsan> this is more worrying to me than gen2 +11:17 < dammsan> but of course it sucks to have breakage +11:18 < horms> can't we just post a fix. the use of BUG_ON seems completely bogus: is it really an error that should take the system down? +11:18 < dammsan> maybe we can fix it with a hackfest at peripericon +11:19 < horms> right, if its still around then it would be a good time to spend some energy on it +11:19 < dammsan> i think so +11:19 < horms> or douse our sorrows in local beer :) +11:19 < dammsan> we can share our time =) +11:19 < dammsan> may have to test on both alt and lager +11:20 < horms> there are many options for Gen2 +11:20 < geertu> horms: Please read my report. Before the (old) BUG_ON() started to trigger, there was already a ULL pointer dereference, introduced by an earlier commit in the series +11:20 < geertu> s/ULL/NULL/ +11:20 < horms> geertu: ok, sorry for jumping to conclusions +11:20 * geertu no media expert +11:21 < dammsan> geertu: do you agree that trying to fix this during peripericon may make sense? +11:21 < geertu> dammsan: do we have all required test peripherals? +11:21 < dammsan> it must be one of our major headaches at the moment +11:22 < dammsan> i don't know how to trigger it i'm afraid +11:22 < geertu> just boot ;-) +11:22 < dammsan> but VSP is usually a memory-to-memory device +11:22 < dammsan> and all Gen2 SoCs have VSP +11:22 < horms> i would suggest moving before peripericon if its a major headache +11:22 < geertu> Now, fixing the crash doesn't mean the system will work +11:23 < dammsan> so can some magician make laurent appear? +11:23 < geertu> Laurent also mentioned user-space impact +11:23 < geertu> which may please Linus even less +11:23 < dammsan> yeah, this has "unpleasant" written all over it +11:25 < dammsan> do we have any major headache for the core group? +11:26 < horms> Mauro does seem to have acknowledged there is a problem, perhaps there is hope of a peaceful resolution to the problem +11:26 < geertu> yeah, he just sent private email to Javier and me. He's on holidays and asks Javier to look into it. +11:27 < geertu> Topic 3. Status check for tasks from last meeting - what is remaining? +11:28 < horms> Our old friend mode pins +11:28 < horms> I guess that is worthy of a slot at peripericon +11:30 < horms> On the integration coverage side, things are moving forwads slowly and surely. I don't see any major headaches at this time.

I take it that is not yet the case. +10:45 < neg> ofc, I was unsure you told me you tentative queued them up :) +10:45 < horms> oh, ok. +10:45 < horms> what were the patch subjects? +10:46 < neg> [PATCH v3 7/8] ARM: dts: r8a7790: add iommus to dmac0 and dmac1 +10:46 < neg> and I'm sorry you wrote deferred not tentative my bad +10:46 < horms> ok, at least we agree :) +10:47 < neg> other than that I hade a first go at the DMAC errta, got Laurents dmatest to work on gen2 but it fails for all channels on gen3 need to do more work there +10:47 < pinchartl> all channels ? nice :-) +10:48 < neg> I guess it's someting else that mess stuff up ;) +10:51 < shimoda> for gen3 no SYS-DMAC + IPMMU, I think we have to use magnus' patches +10:51 < shimoda> it is already into topic branch? +10:52 < pinchartl> in which power domains are the iommus ? +10:52 < geertu> topic/ipmmu-multi-arch-v1 +10:52 < geertu> topic/r8a7795-ipmmu-rfc +10:54 < neg> IIRC I did my initial test based on renesas-drivers-2016-02-09-v4.5-rc9 +10:54 < neg> s/rc9/rc3 +10:55 < shimoda> geertu: thanks for the info. +10:55 < neg> but I did not try as much as I wanted so I would like another go +10:57 < pinchartl> next topic ? or has everybody fallen asleep ? +10:58 < geertu> Topic 2. Status check for tasks from last meeting - what is remaining? +10:58 < horms> lets move on +10:58 < geertu> earlycon is in +10:58 < geertu> irqc ra7795 is half-completed, according to Magnus +10:59 < horms> is the rfc half ready or is the whole thing half way to being merged? +10:59 < geertu> pfc improve documentation is queued for pull request +10:59 * geertu checks chat with Magnus +11:00 < geertu> Remaining INTC-EX issue is the unknown parent clock, which Morimoto-san and Shimoda-san will check? +11:01 < horms> ok, sounds simple enough +11:01 < geertu> r8a7795 SYS-DMAC integration is queued by Simon +11:02 < morimoto> geertu: I got same request from Magnus +11:02 < geertu> r8a7795 Cache topology is halfway +11:02 < morimoto> I will ask it to HW guy tomorrow +11:02 < geertu> morimoto: I know ;-) +11:02 < geertu> morimoto: Thx! +11:03 < geertu> Any other task status updates? +11:03 < horms> l2c patches? +11:04 < horms> fwiw, they look good to me and i plan to merge them +11:04 < geertu> == r8a7795 (+ other :-) Cache topology +11:04 < geertu> thx +11:05 < horms> yes. not stricktly on topic +11:05 < shimoda> how about PFC,v4.6,plan,?,PFC 1.8v switching +11:05 < shimoda> ? +11:06 < geertu> That's not assigned yet. +11:07 < geertu> But if I'm not mistaken, Wolfram was going to look into it for his SDHI work? +11:08 < shimoda> i see, so I will ask Wolfram-san on next I/O meeting +11:10 < geertu> Simon: do you plan to queue the fixes for writing to .text for v4.5? +11:10 < horms> Yes +11:11 < geertu> OK, thx +11:11 < horms> I thought I did so this morning +11:11 < geertu> I think it's queued for v4.6 +11:11 < horms> oh ok +11:11 < horms> yes, that would be right +11:11 < horms> are they fixes for v4.5? +11:12 < geertu> Not having them will cause a crash on suspend as soon as Linus will merge rmk's branch for v4.6. +11:12 < geertu> Which may happen before arm-soc is merged. +11:12 < geertu> So I think it's safer to fast track them to v4.5. +11:13 < horms> ok, it seems that it wouldn't hurt to ask the ARM SoC maintainers +11:13 < horms> it would help me to make my case if i knew which patch(es) in RMK's branch you are referring to. +11:13 < geertu> BTW, you can already trigger the crash if you enable CONFIG_DEBUG_RODATA=y now +11:14 < geertu> That was in the cover letter +11:14 < horms> of course :) +11:14 < horms> i'll see about sending them to v4.5 +11:14 < geertu> 25362dc496edaf17f714c0fecd8b3eb79670207b +11:14 < geertu> ARM: 8501/1: mm: flip priority of CONFIG_DEBUG_RODATA +11:15 < horms> I sent myself an email about it to read tomorrow morning +11:16 < geertu> OK, thanks +11:16 < geertu> Topic 3. RAVB / GPIO +11:17 < geertu> Waiting up to 110 more seconds for network. +11:17 < geertu> Seen in v4.5-rc3 and later +11:17 < pinchartl> could it be related to the nfsroot issues I'm seeing ? +11:18 < pinchartl> [ 65.247123] nfs: server 192.168.1.47 not responding, still trying +11:18 < pinchartl> [ 65.261947] nfs: server 192.168.1.47 OK +11:18 < horms> probably not +11:18 < horms> or at least that is a different manifestation +11:18 < geertu> Last week's renesas-drivers already had the RFC fix for rcar-gpio +11:18 < horms> i don't even get an address via DHCP +11:18 < geertu> The PHY interrupt doesn't come through because the rcar-gpio instance is suspended +11:19 < horms> right. so your patches address this. but I wonder if they have any chance of making it into v4.5. +11:19 < horms> If not I supose we have to live with broken ethernet +11:19 < geertu> Before v4.5-rc3, the PHY driver accidentally kept on polling. When that was fixed, it broke ravb on salvator-x +11:20 < geertu> Probably not a chance. +11:20 < horms> which i guess is better than living with no cpg as we did in v4.4 +11:20 < geertu> ;-) +11:20 < geertu> Does it work if you comment out the phy interrupt in the dts? +11:20 < horms> Ok, at least I'll have something to talk about in Tokyo next week +11:20 < geertu> (haven't tried myself, busy fixing bugs in -next) +11:20 < horms> I can try +11:23 < geertu> Lemme try myself +11:23 < horms> fwiw i'm trying +11:24 < geertu> works! +11:24 < horms> excellent +11:24 < horms> i guess we have found our work-around +11:24 < geertu> Yeah, DT describes the hardware ;-) +11:25 < geertu> Shall we add a quirk that removes the interrupt if present? +11:25 < geertu> Would be a good exercise to prepare for ESx.y DT fixups +11:25 < pinchartl> geertu: shall we fix the root cause ? :-) +11:26 < horms> i think we know the root cause +11:26 < geertu> In the Linux kernel, we never fix root causes ;-) +11:26 < horms> and i agree any work around should go into .c not dt +11:28 < geertu> We can get a workaround in v4.5-rc7 if needed, can't we? +11:28 < horms> we can try +11:30 < geertu> Should we stick a pm_runtime_get_sync() in rcar_gpio_probe() instead? +11:30 < geertu> That would help HDMI, too +11:31 < horms> its a posibility +11:31 < horms> do we expect HDMI to be effected: i.e. for it go go into mainline before the root cause is fixed? +11:32 < geertu> HDMI on Koelsch has been broken due to this for a while. +11:33 < horms> ok, then it does seem like a good idea from my armchair point of view +11:34 < geertu> OK, will go that way for today's renesas-drivers +11:34 < horms> great +11:34 < horms> Hopefully Florian reads your email before he spends any time on the problem +11:35 < geertu> ;-) +11:37 < pinchartl> anything else for today or can I have lunch ? +11:37 < geertu> I think we're finished +11:37 < geertu> Thanks for joining! diff --git a/wiki/Chat_log/20160223-io-chatlog b/wiki/Chat_log/20160223-io-chatlog new file mode 100644 index 0000000..b6c74ba --- /dev/null +++ b/wiki/Chat_log/20160223-io-chatlog @@ -0,0 +1,234 @@ +--- Log opened Tue Feb 23 08:56:22 2016 +08:56 -!- wsa_ [~wsa@79.226.92.116] has joined #periperi-io +08:56 -!- Irssi: #periperi-io: Total of 2 nicks [1 ops, 0 halfops, 0 voices, 1 normal] +08:56 -!- Irssi: Join to #periperi-io was synced in 0 secs +09:00 -!- geertu [~geert@84.195.106.123] has joined #periperi-io +09:01 < geertu> Hi +09:01 <@horms> hi geertu +09:02 < wsa_> hi geert +09:02 < wsa_> hi simon +09:02 <@horms> hi wsa_ +09:03 -!- morimoto [~user@relprex1.renesas.com] has joined #periperi-io +09:03 < morimoto> Hi +09:03 < wsa_> hi morimoto-san +09:03 < morimoto> shimoda-san will be here +09:03 < morimoto> soon +09:04 < wsa_> good +09:04 -!- shimoda [~shimoda@relprex1.renesas.com] has joined #periperi-io +09:04 < shimoda> hi +09:04 < wsa_> hi shimoda-san +09:04 < shimoda> I'm sorry for late +09:05 < wsa_> no worries +09:05 < wsa_> but let's get started +09:05 < wsa_> any questions to the updates I did to the todo file? any further updates? +09:06 <@horms> none from my side +09:06 * geertu checks git +09:07 < wsa_> horms: I will apply your ARCH_RENESAS patch for I2C today or tomorrow +09:08 <@horms> thanks.

The SH4 is not in DT, and A3SH would be in C (or not) after the rework. +10:57 < pinchartl> sounds good to me +10:58 < morimoto> geertu: about SH4, it seems option. But we don't know what does this "option" mean +10:59 < geertu> morimoto: And you cannot check for its presence in the Product Register (PRR), as that contains ARM cores only (CA57/CA53/CR7) +10:59 < geertu> pinchartl: I'm also wondering if the SH4 got disabled by the firmware update we did at PeriPeriCon. +11:00 < pinchartl> geertu: good question +11:01 < geertu> pinchartl: Anyway, you have to leave now, right? +11:01 < morimoto> geertu: do you need to use it ? +11:01 < pinchartl> geertu: yes, sorry about that +11:01 < geertu> morimoto: No, we don't need to use it. +11:02 < pinchartl> morimoto: we don't, but while testing Geert's SYSC patch series, I found out the system would freeze due to the driver trying to disable the A3SH power domain +11:02 < pinchartl> geertu: could be useful to check the boot loader sources to see if it touches that power domain +11:02 < geertu> morimoto: But Laurent found out the A3VC power area (which he needs for multimedia) fails to power up if the A3SH power area was touched before. +11:03 < morimoto> Hmm... So you want to know detail of it to HW team ? +11:03 < geertu> morimoto: yes please +11:04 * pinchartl is gone +11:04 < pinchartl> have a nice day/evening +11:04 < geertu> thx, bye! +11:06 < morimoto> geertu: can you please send me detail mail about that ?

But this will be next. +09:37 < wsa_> but I'll keep that in mind! +09:38 < shimoda> wsa_: i see about UHS support. +09:38 < shimoda> about gen3 DMA.

[18:03] +<pinchartl> we have no shortage of work +<pinchartl> and everything is urgent +<pinchartl> yet, the contracts will be reduced to 50% for April +<pinchartl> how do we deal with that ? +<dammsan> i doubt it will be very visible from the outside [18:04] +<dammsan> if one month drops and two other months increases +<dammsan> but that is not your concern perhaps? =) +<pinchartl> does that mean May and June could be covered by contracts at 125% + then ? +<morimoto> I think Base 50% + Additional 25% + Additional 25% [18:05] +<dammsan> the total amount of cash remains unchanged +<pinchartl> if we have 50 in April, 100 in May and 100 in June, that's 250 + instead of 300 +<pinchartl> (I'm talking about development time, no cash) +<dammsan> but we never have that amount of time anyway +<dammsan> with other customers and paperwork due dates [18:06] +<pinchartl> let's put it another way +<dammsan> so first month is always short before invoice? +<dammsan> sure, i'll be silent =) +<pinchartl> when I have to send a report by the 17th of the first month, I + still work from the 17th to the end of the month [18:07] +<dammsan> uli___: please chat with me using google chat about tasks +<uli___> ok +<dammsan> pinchartl: sure +<pinchartl> are we expected to work less during April compared to what we've + done so far ? +<dammsan> you may include the second half of your patches in the second + report? +<pinchartl> less = 50% of a normal month +<dammsan> it is up to you really [18:08] +<pinchartl> dammsan: I might, but I still work during the second half of the + last month of the contract +<dammsan> since you only have the base contract +<dammsan> you will not be sure how much you can adjust your work later on +<pinchartl> my point is that, if we reduce the contract scope to 50% for April + and leave it to 100% in May and June, that's 250 work time points + instead of the usual 300 +<pinchartl> meaning development will be slowed down [18:09] +<dammsan> so may and june may get more busy +<dammsan> so if you want to reduce your burden then work a bit more for base + in april to make room for may and june? +<pinchartl> so, to put it another way, is Renesas asking us to work for free + half of April because we might get more work later ? +<dammsan> no? +<dammsan> renesas is asking you to do what is written in the contract. [18:10] +<dammsan> period. +<pinchartl> but at the same time they're asking us to deliver features faster + than what we've done so far +<dammsan> hm..? +<pinchartl> "please deliver faster, but work only 50% to do so" +<pinchartl> doesn't make too much sense to me :-) +<dammsan> that portion that i don't understand +<dammsan> who asks you to deliver sooner? +<pinchartl> you mentioned earlier that HDMI output for Gen3 should be done + before v4.7 if possible [18:11] +<pinchartl> and that the VSP1 issues are expected to be fixed already +<pinchartl> that means we're considered to be too slow +<dammsan> i think you are right [18:12] +<dammsan> sorry about that feeling +<dammsan> but it is related to too much work and too little resources +<dammsan> about that HDMI Gen3 drop it is just from my side that we should aim + for something sooner IMO +<dammsan> but we need to look at the big picture [18:13] +<pinchartl> so, what are we expected to do ? +<dammsan> with reduced amount of time in April it sure looks like April will + move slower +<dammsan> we do what we can do with the amount of time we have? +<dammsan> following priority? +<pinchartl> I can certainly leave the option to all developers in the team to + work 100% in April while being paid 50% +<pinchartl> but I won't request anyone to do so +<dammsan> of course spreading out work evenly over 3 months makes sense + [18:14] +<dammsan> but we need time to finalize the additional tasks +<dammsan> so there will unfortunately be a delay +<pinchartl> the additional tasks for May and June will cover 50%, right ? + [18:15] +<pinchartl> so that's 250 instead of 300 in total for Q2, correct ? +<dammsan> in my mind they may be more fixed-price than time based +<dammsan> but we need to discuss more +<dammsan> 250 has never been the goal [18:16] +<dammsan> it has always been 300 +<dammsan> so we need to find a good balance for the amount of work in the last + two months of the quarter +<pinchartl> could it be that the additional tasks will cover more than 50%, + resulting in ~300 for Q2 in total ? [18:17] +<dammsan> it depends on how much time each individual has +<dammsan> but yes, if the total should be 300 then it must become like that +<pinchartl> of course, but do you think it could be so ? +<dammsan> it could be how? [18:18] +<pinchartl> because in that case it could make sense to work more than what + the contract covers in April and deliver the result in May and + June +<pinchartl> (but again it would be a personal decision, I won't request anyone + to do so) +<dammsan> yes, working more earlier would be excellent +<dammsan> but no papers yet i'm afraid [18:19] +<pinchartl> I'm sure Renesas won't complain if we work more than we're paid + :-) +<dammsan> so it is difficult to say what to work on =) +<pinchartl> the question is whether there's a reasonable chance that that + "overtime" could be covered by additional tasks in May and June +<dammsan> define overtime =) +<pinchartl> working 100% in April instead of 50% [18:20] +<pinchartl> obviously guessing what would be requested in May and June +<pinchartl> but we can have a reasonable guess +<pinchartl> I'm pretty sure HDMI output will be requested for instance +<pinchartl> if you tell me now that, if I can prepare already in April, + there's a 90% chance Renesas will want to request more from me in + May and June, there's an incentive [18:22] +<pinchartl> if the chance is 5%, less so :-) +<pinchartl> I'm trying to understand what will happen +<dammsan> ifok i see [18:23] +<dammsan> (sorry, got kicked out from my VM) +<pinchartl> and with the multiple hops between our team and the decision + makers in Renesas, plus the language barrier and the business + culture differences, it's hard for me to be confident about my + understanding of the situation +<dammsan> if people are willing to work more w/o papers +<dammsan> then i propose that we simply list one major task for each member + that can be focused on in april and we think will be included as + additional task [18:24] +<pinchartl> ok +<pinchartl> I believe we can keep our current focus in April [18:25] +<pinchartl> on HDMI, VIN and VSP +<pinchartl> each will require more than 10 days (50%) to complete +<pinchartl> they might be covered by the base contract or additional tasks in + May and June +<pinchartl> but in both cases I believe they will be covered [18:26] +<dammsan> yes, good plan +<pinchartl> we need to make sure we only include 50% of the deliverables in + the April report though +<dammsan> no need to play too many paper games IMO +<dammsan> but it is up to you how you want to roll +<dammsan> if code is queued up and working then report contents are not + important [18:27] +<dammsan> just a formality +<pinchartl> I personally won't change my work pace for April (well, except + that I won't code much during ELC) +<dammsan> same here +<pinchartl> ok [18:28] +<pinchartl> should I record this in the meeting report or should I leave it + out ? +<neg> same here if it's ok for me to post patches based on datasheets while I + do not have a contract [18:29] +<pinchartl> I don't think your NDA expires at the end of the SoW +<dammsan> it is up to you +<pinchartl> so that shouldn't be a problem +<pinchartl> I'll leave it out of the meeting minutes, I'm not sure how I + should phrase it [18:30] +<pinchartl> last topic +<dammsan> my only additional comment about this is +<pinchartl> yes ? +<dammsan> if you are planning vacation, feel free to do so in april instead of + may/june =) [18:31] +<pinchartl> good point :-) +<pinchartl> I'll write that down +<dammsan> thanks +<neg> ok thanks, it was the NDA part that gave me the most grief :) +<pinchartl> neg: please read your NDA in details though [18:32] +<pinchartl> I'm not a lawyer +<pinchartl> topic 4 [18:33] +<pinchartl> next meeting +<pinchartl> the next meeting would be in 2 weeks +<pinchartl> which is ELC time +<pinchartl> who will attend ELC ? [18:34] +<pinchartl> Magnus, you said you will be there +<dammsan> yes +<pinchartl> Niklas as well ? +<neg> yes +<pinchartl> Ulrich, you don't plan to attend if I remember correctly ? +<pinchartl> how about Morimoto-san ? +<uli___> correct +<pinchartl> is Morimoto-san stuck in an interrupt storm again ? [18:36] +<dammsan> maybe [18:37] +<dammsan> he is coming +<dammsan> i know it =) +<pinchartl> :-) [18:38] +<morimoto> I was ked-napped by Magnus, so yes I will got to ELC +<pinchartl> :-D +<pinchartl> very nice +<pinchartl> we'll have the next meeting there +<morimoto> F2F meeting :) +<pinchartl> I think that's it for today then +<pinchartl> thank you everybody for joining [18:39] +<morimoto> thanks +<neg> pinchartl: do you have any more information about the mini multimedia + meeting? +<pinchartl> it will be held on Thursday +<dammsan> pinchartl: is this meeting including members outside this group? + [18:40] +<pinchartl> that's all I know for now +<dammsan> or is it for our group? +<pinchartl> that's the linux media mini-summit +<dammsan> ok cool +<pinchartl> we'll have another meeting for our group during the week +<dammsan> any ideas when to meet? +<morimoto> My departure time is 8th April +<dammsan> for me meeting with you guys is top prio [18:41] +<dammsan> it may make sense to decide right away if possible +<neg> ok I got a mail from Hans telling me to let Maruo know if I wanted to + attend, I drop him a mail and see if I can find out more +<pinchartl> let me see if the conference schedule has been published +<morimoto> Do I need something for this mini-summit ? [18:42] +<neg> I have nothing else planed during ELC so anytime works for periperi + meetup +<pinchartl> ok, my talk is on Tuesday morning [18:43] +<pinchartl> morimoto: if you want to join the mini-summit you just have to be + there and listen. and possibly talk too :-) +<pinchartl> I've sent a mail and CC'ed the three of you to ask if we have + seats [18:44] +<pinchartl> I think we will +<pinchartl> I'd prefer the F2F meeting to be on Tuesday afternoon or on + Wednesday +<morimoto> pinchartl: OK, no ticket, no register are needed +<morimoto> Thanks [18:45] +<dammsan> i'm fine either Tuesday or Wednesday +<pinchartl> let's go for Tuesday right after lunch ? +<pinchartl> or maybe starting at lunch time ? [18:46] +<morimoto> pinchartl: every time is OK for me during 4th - 8th (morning) + [18:47] +<dammsan> start at lunch time must be good +<pinchartl> I'll see if I can find a nice place to have a team lunch away from + the crowd [18:48] +<pinchartl> on Tuesday +<neg> works for me +<pinchartl> ok, I think we're done +<pinchartl> and I have to go +<pinchartl> good timing :-) +<pinchartl> thank you all for attending +<pinchartl> and see you in San Diego ! +<dammsan> thank you!! +<neg> thanks +<dammsan> see ya in CA +<morimoto> Thanks [18:49] diff --git a/wiki/Chat_log/20160411-io-chatlog b/wiki/Chat_log/20160411-io-chatlog new file mode 100644 index 0000000..cea2140 --- /dev/null +++ b/wiki/Chat_log/20160411-io-chatlog @@ -0,0 +1,195 @@ +--- Log opened Mon Apr 11 09:55:04 2016 +09:55 -!- wsa_ [~wsa@p4FE259C0.dip0.t-ipconnect.de] has joined #periperi-io +09:55 -!- Irssi: #periperi-io: Total of 6 nicks [1 ops, 0 halfops, 0 voices, 5 normal] +09:55 -!- Irssi: Join to #periperi-io was synced in 0 secs +09:55 < wsa_> hiya +09:55 < wsa_> wow +09:55 < horms> Hi wsa_ +09:56 -!- shimoda [~shimoda@relprex1.renesas.com] has joined #periperi-io +09:56 < wsa_> hi guys +09:56 < shimoda> hi +09:56 < morimoto> hi +09:56 < neg> morning +09:56 < uli___> hi +09:56 < wsa_> nice to see you again! +09:57 < wsa_> so, ELC was good? +09:57 < neg> yes it was nice +09:58 < neg> good for me who are new to meet people in the flesh +09:58 < morimoto> yes I think so +09:58 < wsa_> neg: yes, hallway track is usually my fav, too :) +09:59 < wsa_> okay, then, let's get started +10:00 < wsa_> I didn't notice updates for the todo file, please tell me if I missed something +10:00 < wsa_> from my side, SDHI support for UHS-I/SDR50 was merged +10:00 < wsa_> and WDT support should show up in linux-next any day +10:01 < wsa_> SDHI probably needs DMA updates to achieve full speed +10:01 <@geertu> wsa: Have you tried Günter's restart series? +10:01 < shimoda> oh, it's nice!

If not, I'm curious to know its motivation. +10:29 < wsa_> IIRC think it was a customer request? shimoda-san, do you recall more? +10:29 <@geertu> The other SPI on Gen3 is MSIOF, which has hardware issues that are supposed to be fixed in ES2, or in M3-W +10:30 < horms> Ok, so it might be used in the context of MSIOF on Gen 3? +10:30 <@geertu> And DRIF, which is sort-of half-duplex SPI slave +10:30 < wsa_> could we use Gen2 for the prototype? +10:30 <@geertu> That's what it says: "... for R-Car Gen2" +10:30 < wsa_> morimoto: can i add khiem-san to the todo file as "khiem"? +10:30 < horms> wsa_: no argument about prototyping on Gen 2 +10:30 < horms> I was just wondering what the end game was +10:30 < wsa_> geertu: got me there :D +10:31 < horms> neg: my notes tell me SYS-DMAC Supports I2C 0 to 6 and IIC-DVFS. v0.51e 17.1.1 +10:31 < morimoto> wsa_: that is good idea for me :) +10:31 < horms> neg: in case that is of any help +10:32 < neg> horms: thanks +10:33 < wsa_> uli___: how does implementing SPI slave support sound to you? that's a new thing for linux... +10:33 < horms> neg: i think the implication is that you can do dma to/from 40 bit addresses using the SYS-DMAC. I don't have notes of any other dma capabilities for I2C +10:33 < wsa_> geertu: would you be ok to reassign the task? +10:34 < uli___> i have no clue about spi, so i might as well as well have a look at it... +10:34 <@geertu> wsa: SPI? I think it may be a bit premature +10:35 < wsa_> geertu: what do you mean? +10:36 <@geertu> wsa: There will be additional contracts, right? +10:36 <@geertu> I already spent lots of investigation about SPI slave +10:36 < wsa_> shimoda: how is USB going? is there a place where you could need help? +10:38 < neg> horms: nice, the manual even have flow-charts for DMA operation :) +10:38 < horms> :) +10:39 < wsa_> geertu: i see +10:39 < shimoda> i am doing USB3-host, USB-PHY tasks.

After hot-unplug, hot-plug no longer works in v2.5.0 +10:12 < horms> _I_ am not aware of any regressions +10:12 < khiemnguyen> you tried with CPU0, right ? +10:12 < horms> let me check +10:12 < khiemnguyen> CPU0 has a limitation for CPU Hotplug, since the secure side will run some secure services in CPU0 all the time. +10:13 < khiemnguyen> Please try CPU Hotplug with CPU1/2/3 only. +10:13 < horms> I only tried CPU1 +10:13 < horms> What happens on CPU0? +10:14 < khiemnguyen> the secure side will run some secure services in CPU0 all the time. +10:14 < khiemnguyen> CPU0 should not be hotplug. +10:14 < horms> ok +10:15 < horms> so if it is unplugged we might see some problems? like undefinded behaviour? +10:15 < khiemnguyen> so if it is unplugged we might see some problems? like undefinded behaviour? --> yes. +10:16 < geertu> Hmm... +10:16 < geertu> It would be better if the operation just failed with an error code +10:16 < horms> yes, i think we should disallow it somehow +10:16 < geertu> Else we have to explicitly have a check to prevent the user from doing that +10:17 < horms> oh, you mean the fimrware should return an error? +10:17 < khiemnguyen> Yes. But the firmware has not supported that feature yet. +10:18 < geertu> horms: Yes, I mean the firmware +10:18 < khiemnguyen> Therefore, in in-house BSP, I have created a work-around patch to disable CPUHotplug request in CPU0. +10:18 < pinchartl> as it's a firmware requirement that CPU0 can't be unplugged, it would make sense for the firmware to implement the check +10:18 < horms> khiemnguyen: ok. good to know. do you know if that is planned? +10:19 < khiemnguyen> as it's a firmware requirement that CPU0 can't be unplugged, it would make sense for the firmware to implement the check ---> but they put it as low-priority now. since we also has a work-round patch in Linux kernel. +10:19 < horms> ok. but from an upstream point of view it seems like a priority. could you pass that information on? +10:19 < geertu> khiemnguyen: if we include the workaround in upstream, ideally it should check for the firmware version, to know when to apply it or not. +10:20 < geertu> And the question remains where in the code to put the check (no board code) +10:20 < khiemnguyen> do you know if that is planned? ---> official support in firmware might be available by E/this year, I heard. +10:20 < pinchartl> geertu: I'd keep the workaround away from upstream +10:21 < pinchartl> upstreaming CPU hotplug would then require a firmware that supports hotplug properly +10:21 < pinchartl> putting some pressure to implement that :-) +10:21 < khiemnguyen> And the question remains where in the code to put the check (no board code) ---> huhm..., to check firmware version, we need more than that, need optee linux driver to communicate with secure side. +10:21 < geertu> pinchartl: Even better. Except that we alrady have hotplug in upstream/ +10:21 < horms> pinchartl: fwiw, CPU hotplug is already upstream +10:22 < pinchartl> well, fixing it upstream then I suppose :-) +10:22 < khiemnguyen> yeah, CPU Hotplug is already supported in usptream, for CPU1/2/3, given that the firmware is taken from Yocto v2.4.0 or later. +10:24 < geertu> Things like CPU hotplug are enabled automagically once you have a PSCI platform. +10:24 < geertu> Whether they work or not is a different issue... +10:24 < shimoda> FYI, khiem-san's workaround is 9c910ad5a1e60b302e88ef394bcff84018e69adc in renesas-bsp.git +10:25 < horms> khiemnguyen: is there any possibility we could ask for the feature to be in firmware sooner than later. it would really help things on the upstream side. +10:26 < geertu> BTW, what's "DDR training"? +10:26 < khiemnguyen> Let me know the feature, will try to confirm with secure team. +10:27 < horms> khiemnguyen: thanks. I think the feature request is to return an error for a request to take CPU0 down. +10:27 < horms> so long as doing so causes problems. +10:27 < khiemnguyen> DDR training is rountine activity to check SDRAM operation and adjust SDRAM parameters for best performance. +10:27 < pinchartl> geertu: it's automatic detection (and configuration) of the DDR memory controller to take into account board design +10:27 < pinchartl> including traces length for instance +10:28 < geertu> OK, thx +10:28 < geertu> Another issue with the firmware upgrade was "secret" DDR clock frequency +10:29 < geertu> which requires public changes in the r8a7795 CPG/MSSR driver. +10:29 < pinchartl> "Typically, a data training sequence is performed at startup to find the optimum position for the DQS input buffer enable signal. This can be accomplished by performing reads with deterministic patterns while sweeping through the possible system latency values." +10:29 < pinchartl> (http://www.design-reuse.com/articles/13805/the-love-hate-relationship-with-ddr-sdram-controllers.html) +10:30 < khiemnguyen> "secret" DDR clock frequency --> 2400 ? +10:30 < horms> geertu: my understanding is that there are some hw bugs relating to DDR. and that a resolution is not at hand at this time. iirc only 2400 works at this time. (my memory may be entirely faulty on this topic) +10:32 < geertu> khiemnguyen:yes, 2400, cfr. +10:32 < geertu> BSP kernel +10:32 < geertu> MD19 MD17 : PLL3 mult +10:32 < geertu> ------------------------------- +10:32 < geertu> 1 0 : x144 (for DDR2400) +10:32 < geertu> 1 1 : x192 (for DDR1600) +10:32 < khiemnguyen> Currently, let's keep using DDR1600. +10:32 < geertu> khiemnguyen: That's an option?

RSND support +<morimoto> I sent prototype patch for 1. +<morimoto> and got any response +<pinchartl> I've seen that. would you like me to review it ? +<morimoto> Thanks, but it seems OK now [16:03] +<morimoto> I think I understand graph concept +<morimoto> but, not yet understand motivation +*** horms_ (~horms@124-171-1-229.dyn.iinet.net.au) has joined channel + #periperi +<pinchartl> that I can explain +<morimoto> please [16:04] +<pinchartl> it came from V4L2 +<morimoto> Yeah, I know. my motivation means +<pinchartl> complex camera devices are made of multiple hardware devices +<pinchartl> camera sensor, CSI receiver, ISP, lens controller, flash + controller, ... +<pinchartl> those devices can be inside the SoC or on-board [16:05] +<pinchartl> and they can be mixed and matched on different SoCs/boards +<pinchartl> so we have, in V4L2, a framework to support them using multiple + drivers +<pinchartl> it's a bit similar to ASoC +<pinchartl> when we had to create DT bindings +<pinchartl> we needed a way to express how the devices were connected together + from a data flow point of view +<pinchartl> like saying that the camera sensor output is connected to the + input of CSI-2 receiver 2 [16:06] +<pinchartl> or that the output of CSI-2 receiver 0 is connected to input 3 of + the ISP +<pinchartl> essentially, that's expressing a graph of data flow connections +<pinchartl> hence the OF graph bindings [16:07] +<pinchartl> a device represented in DT can have multiple ports +<pinchartl> those are connection points through which data flows +<pinchartl> and to represent connections between ports, we use endpoints +<pinchartl> and endpoint repreent one end of a connection [16:08] +<pinchartl> we need the endpoints because a port on one DT node can be + connected to ports of multiple other DT nodes +<pinchartl> is that clearer ? +<morimoto> 80% [16:09] +<morimoto> I understand that the connection is very complex. +<morimoto> but my question is +<dammsan> pinchartl: do the ports map directly to hardware? +<pinchartl> yes they do +<pinchartl> so do the connections +<dammsan> morimoto-san was saying? [16:10] +<morimoto> my question is +<morimoto> 1) we can happy to find-out its connection when probing timing ? +<morimoto> 2) does graph supports runtime switching ?? +<morimoto> do we would like to find its connection on probe timing ?? +<morimoto> we can use phandle for connection itself ? [16:11] +<morimoto> (for 1. question) +<pinchartl> I'm not sure to understand the first question +<morimoto> I think phandle can do that ? [16:12] +<morimoto> if we would like to know "connection" +<pinchartl> we use phandles to describe connections +<pinchartl> a connection is a link between two ports +<pinchartl> it's represented as a phandle to an endpoint [16:13] +<pinchartl> the endpoint on one side of the connection references the endpoint + on the other side through a phandle, with the remote-endpoint + property +<morimoto> Is this means, driver want to know who is connected, on probe time + ? [16:14] +<morimoto> or which channel is used ? +<pinchartl> that's what drivers usually do +<pinchartl> note that the connections in DT describe the possible hardware + connections [16:15] +<pinchartl> not the active connections at a given point of time +<pinchartl> DT will tell that device A and device B are connected at the + hardware level +<pinchartl> it will not tell whether the connection is currently in use +<pinchartl> so DT will show all possible connections +<morimoto> "all possible connections" [16:16] +<morimoto> is this the purpose of graph ? +<pinchartl> the purpose of the graph is to describe how the hardware pieces + are connected together +<pinchartl> that's all +<morimoto> Hmm... +<morimoto> OK, and it indicate connection only [16:17] +<morimoto> can't do runtime switch +<pinchartl> it certainly doesn't handle that, no +<pinchartl> you can't modify connections at runtime [16:18] +<morimoto> OK +<dammsan> pinchartl: if you want to perform a run time switch, what do you + use? +<pinchartl> unless you solder new wires to the board to create new connections +<pinchartl> but I think that's out of scope :-) +<pinchartl> runtime activation or deactivation of a connection is left for the + driver to handle, it doesn't involve DT +<pinchartl> DT describes the hardware +* geertu is dreaming of DT overlays... [16:19] +<dammsan> sure, i understand +<pinchartl> it describes how the data signals are routed on the board or in + the SoC +<dammsan> but how does the typical driver perform activation/deactivtation? +<pinchartl> it's subsystem-specific [16:21] +<dammsan> ok i see +<dammsan> thanks +<pinchartl> even the concept of connection activation/deactivtation? is + subsystem-specific +<morimoto> my patch was super quick hack for ASoC, not good for full-graph. +<morimoto> my patch reviewer said that current ASoC style is not good match to + graph style +<pinchartl> it's not defined by the DT bindings +<pinchartl> who reviewed it ? +<morimoto> Jean-Francois Moine [16:22] +<pinchartl> did +<morimoto> it seems he is working for this graph + ASoC from last year +<pinchartl> did Lars comment too ? +<morimoto> No comment from Lars +<morimoto> graph + ASoC patch was posted last year, but not accepted [16:23] +<morimoto> and he said (if my understanding was correct) +<morimoto> it need different style [16:24] +<morimoto> total +<morimoto> in total +<morimoto> I couldn't understand what is the next step for graph + ASoC + [16:25] +<pinchartl> did he explain what different style ? +<morimoto> Current ASoC is using CPU driver + Codec driver + Card driver +<morimoto> but (if my understanding was correct) [16:26] +<morimoto> graph + ASoC doens't need Card driver +<morimoto> And CPU driver needs update +<morimoto> in my understand +<pinchartl> that's correct I believe [16:27] +<morimoto> I need more investigate this topic +<morimoto> DT point <-> Code point +<morimoto> I think this is the reason why ASoC had Card driver... [16:28] +<morimoto> OK, this is current my DT issue +<pinchartl> yes, the card driver is similar in purpose to the OF graph DT + bindings [16:29] +<morimoto> Ahh, OK, this is understandable comment for me +<morimoto> :) +<morimoto> I couldn't 100% understand why graph is needed, because ASoC + already had Card :) [16:30] +<morimoto> And, next 2. HDMI + ASoC +<pinchartl> the idea is that video uses the OF graph DT bindings +<pinchartl> and alsa has the ASoC DT bindings +<pinchartl> and now that we have a connector that can carry both video and + audio, we need to connect the two +<pinchartl> that's the issue +<pinchartl> two totally different DT binding concepts that need to be + connected together [16:31] +<morimoto> I think it is not easy +<morimoto> above Jean-Francois had tring this issue +<morimoto> but not yet accepted [16:32] +<morimoto> and next HDMI sound + ASoC, I know Russel added dw-hdmi-ahb-audio + driver [16:34] +<morimoto> I think DU is using dw-hdmi-bind() function +<morimoto> above is related to it. +<morimoto> I think this driver seems have compatible [16:35] +<morimoto> but, +<morimoto> the data flows is not same as our chip +<morimoto> and our datasheet doesn't indicate detail +<morimoto> dw-hdmi-ahb-audio is using mem -> DMA -> chip [16:36] +<pinchartl> there's no proper upstream solution at this point. Russell + sometimes has, let's say, very personal and peculiar ideas when it + comes to DT bindings or driver framework designs +<morimoto> our case, mem -> SSI -> chip +<pinchartl> by DMA do you mean DMA engine ? +<morimoto> not DMAEngine, it seems this chip has DMA inside [16:37] +<pinchartl> as in the Linux DMA engine API +<pinchartl> ok +<pinchartl> dw-hdmi-ahb-audio might need to be reworked +<morimoto> but our datasheet doesn't show it +<pinchartl> I haven't looked at it, I don't know how it works +<morimoto> it seems this chip is supporting many data transfer style +<morimoto> anyway, I'm asking detail to HW team [16:38] +<pinchartl> ok +<pinchartl> regarding the OF graph DT bindings +<pinchartl> we need to solve the problem of two separate DT bindings existing + for video and audio +<pinchartl> I don't know what will be accepted upstream [16:39] +<pinchartl> it's an open issue, nobody has solved it upstream yet +<morimoto> yeah +<morimoto> I think it is not easy ? +<pinchartl> so I'm afraid this needs new designs, new ideas, and lots of + discussion to agree on a solution with everybody +<pinchartl> it's certainly not easy, no [16:40] +<morimoto> Do you think this is 1st priority ? +<morimoto> Or should I create prototype as 1st step ? +<pinchartl> DT bindings are a stable ABI, so they are a prerequisite for + upstream merge +<morimoto> prototype = HDMI can use sound somehow +<pinchartl> you can certainly create a prototype [16:41] +<pinchartl> if we want to convince people about a given DT bindings scheme we + have to show that it works, and how it works +<pinchartl> so an implementation is needed +<morimoto> Sorry, my prototype means skip DT at this point, and work to HDMI + sound output as 1st [16:42] +<pinchartl> you can do that, but it can't be merged upstream without DT + bindings +<morimoto> Yes, prototype is needed to discussion +<morimoto> Yes. +<morimoto> So, this DT issue is my 1st priority [16:43] +<pinchartl> DT bindings take time to be discussed and agreed on +<pinchartl> so it makes sense to start early +*** wsa_ (~wsa@p4FE25DE7.dip0.t-ipconnect.de) has joined channel #periperi +<morimoto> OK, will try +<pinchartl> but while discussions are ongoing, a prototype of sound support + can certainly be written [16:44] +<pinchartl> the runtime side doesn't depend on DT +<pinchartl> only probind does +<morimoto> I think DT is big issu [16:45] +<morimoto> issue +<morimoto> HDMI + ASoC is big issue +<morimoto> SSI HDMI supoort is not a big issue +<pinchartl> I think I agree, although changes to the dw-hdmi-ahb-audio driver + might not be very easy to get past Russell [16:46] +<morimoto> OK, thanks [16:47] +<morimoto> this is current my headache, oops, progress +<pinchartl> :-) +<pinchartl> so what's your plan ? create a prototype in parallel to the DT + bindings discussions ?

[17:50] +<dammsan> i expect wsa to talk to uli and neg about additional i/o tasks +<dammsan> this will happen this week +<dammsan> and we will know more next week +<uli___> dammsan: wsa_ and i have agreed on a task just before +<wsa_> it happens currently :D +<dammsan> my take on all this is that eaach member can chose how much time to + spend on tasks for the various groups [17:51] +<dammsan> i/o and multimedia gets two chances this quarter +<dammsan> while core gets one +<pinchartl> I can see that becoming complex pretty soon +<dammsan> so uli and neg should talk to the different group leaders about how + they want to spend their time [17:52] +<wsa_> may I ask something about that? +<dammsan> sure +<wsa_> the additional contracts have stricter requirements about deliverables + (like the test-setup and the wiki page) +<wsa_> which I understand +<wsa_> that makes choosing how much to work for this or that group not really + flexible, does it? [17:53] +<wsa_> or am I mixing up things? +<dammsan> a bit [17:54] +<dammsan> so each group leader has to figure out what task to allocate + depending on the available amount of time for each guy +<wsa_> yes [17:55] +<dammsan> we have very little time at this point, and with wikis and whatnot +<dammsan> amount of development time is limited +<dammsan> but amount of development time for each guy +<dammsan> is kind of spread out over the groups +<dammsan> for the leaders i assume they spend the majority of the time on + their own group activity [17:56] +<dammsan> but for members like uli and neg +<dammsan> they have tasks for all the groups +<dammsan> which means also additional tasks for all the groups +<dammsan> and how to split the time between the groups is something that i + think each guy can control +<dammsan> by talking with the group leaders +<dammsan> and each group leader needs to encourage people to join his group + too =) [17:57] +<dammsan> neg: pong? +<pinchartl> stupid question, why does base task for all groups imply + additional tasks for all groups ? +<dammsan> pinchartl: for additional task i think we can follow the base + contract to begin with [17:58] +<dammsan> if needed group leaders can extend beyond their own group [17:59] +<dammsan> i think pinchartl is needed in the core group +<dammsan> and i also think that geert is needed by the i/o group +<dammsan> neg: you can chose how you spend your weeks between the groups for + additional tasks [18:00] +<wsa_> he definately is +<dammsan> does that clarify? +<wsa_> for now, i think so [18:01] +<neg> dammsan: ok, but then I might have missunderstod something. I have + talked to pinchartl about additional multimeda tasks that would fill my + allocated time for additnal tasks. Should I have spread the additonal + work also over core and I/O ? +<pinchartl> dammsan: maybe I'm being thick today, but now that additional + tasks for multimedia have been drafted, with an estimation of the + time required to complete them, how can developers choose how to + allocate their time [18:02] +<dammsan> so each guy knows how many weeks in total that are in their current + base task +<dammsan> this is supposed to be 50% of the total time +<wsa_> i think by doing that neg already chose 100% multimedia group :) + [18:03] +<dammsan> the same amount of time as the base task is supposed to be assigned + to the additional tasks +<wsa_> 100% of the additional tasks that is +<geertu> dammsan: aha? +<dammsan> in my understanding neg is only pinned down to 1/3 of his total time + this quarter [18:04] +<dammsan> of course pinchartl wants him to do more stuff there +<dammsan> and i think he is doing good work for multimedia +<dammsan> neg: if you want to spend 100% of your time with multimedia then you + should do that [18:05] +<dammsan> but i advice you to keep good relationship with all group leaders =) +<dammsan> geertu: you and i have not gotten to talk about the core tasks so + much yet +<dammsan> next week [18:06] +<dammsan> still completely unclear? +<dammsan> =) +<pinchartl> dammsan: it sounds a bit like a big matsuri to me :-) +<neg> ofc, I can do work where it is most needed. I only assumed after the + last multimedia meeting during ELC that my additonal tasks for this + quarter was most needed for multimedia +<wsa_> neg: okay, you go work 100% for multimedia, but buy me a drink at the + next conference ;)))) +<pinchartl> neg: that was my assumption too +<neg> wsa_: ofc :-) +<pinchartl> to be honest I really don't like the idea of internal competition + for time allocation +<wsa_> that is even my assumption +<wsa_> i like working with neg, but I don't really have a task for him [18:07] +<dammsan> pinchartl: there is no competition +<dammsan> it is similar to before, each guy gets to tell which group he wants + to work with +<pinchartl> let's see how it will work for this quarter then [18:08] +<dammsan> yes +<dammsan> pinchartl: please note that only the 5/E task for neg is pinned down +<dammsan> i realise more work is needed, but that's always the casee for all + groups when we are resource starved [18:09] +<dammsan> jinzai will contact each member with additional contracts later this + month +<dammsan> if there are more questions then please bring em on [18:10] +<pinchartl> not from me [18:11] +<pinchartl> we should close the meeting. any additional comment anyone ? + [18:12] +<pinchartl> I'll take that as a no [18:13] +<pinchartl> last topic, next meeting [18:14] +<pinchartl> keeping the current schedule, that should be on the 3rd of May +<pinchartl> however, I will be travelling +<dammsan> can we do + or - 1h offset? +<dammsan> my schedule tends to collide with this [18:15] +<dammsan> but you guys seem ok by yourself, so me being semi-present may not + be such a bad idea +<pinchartl> three options: one week early, one week late, or without me +<pinchartl> (I'm sorry about that) +<dammsan> i think you should be present +<dammsan> i'm ok with the other proposals [18:16] +<pinchartl> any preference anyone ? +<uli___> 9am collides with my sleeping schedule, so i'd vote for +1h :) +<uli___> i'm not particular with the date +<neg> +/- 1 Week will collied with the core meeting [18:17] +<pinchartl> we can do another day +<pinchartl> Wednesday for instance +<neg> works for me +<uli___> i would actually prefer to have all meetings in one week as well +<uli___> i mean in the same week +<pinchartl> I don't think we'll have a lot to talk about in a week [18:18] +<pinchartl> so I propose in three weeks +<pinchartl> I'll send an invitation [18:19] +<pinchartl> that's it for today +<pinchartl> thank you everybody +<pinchartl> and have a nice day/evening +<neg> thanks all +<dammsan> thanks [18:20] +<morimoto> bye [18:22] +<uli___> bye +<morimoto> pinchartl: I will put today's log to Redmine, please update + peripelist [18:23] diff --git a/wiki/Chat_log/20160425-io-chatlog b/wiki/Chat_log/20160425-io-chatlog new file mode 100644 index 0000000..bf88336 --- /dev/null +++ b/wiki/Chat_log/20160425-io-chatlog @@ -0,0 +1,256 @@ +--- Log opened Mon Apr 25 09:56:14 2016 +09:56 -!- wsa_ [~wsa@p4FE25E13.dip0.t-ipconnect.de] has joined #periperi-io +09:56 -!- Irssi: #periperi-io: Total of 2 nicks [1 ops, 0 halfops, 0 voices, 1 normal] +09:56 -!- Irssi: Join to #periperi-io was synced in 1 secs +09:58 -!- neg [~neg@unaffiliated/neg] has joined #periperi-io +09:58 -!- shimoda [~shimoda@relprex3.renesas.com] has joined #periperi-io +09:59 < shimoda> hi +10:00 -!- horms [~horms@124-171-1-229.dyn.iinet.net.au] has joined #periperi-io +10:00 -!- geertu [~geert@d54C36DF3.access.telenet.be] has joined #periperi-io +10:01 -!- Irssi: #periperi-io: Total of 6 nicks [1 ops, 0 halfops, 0 voices, 5 normal] +10:02 < wsa_> hi guys again +10:03 < shimoda> hi +10:03 <@uli___> hi +10:03 < wsa_> i'd like to recap tasks today to see if all is settled after the "additional tasks" change +10:04 < wsa_> and i'd like to do that in alphabetical order +10:04 < wsa_> geert is first +10:04 -!- horms [~horms@124-171-1-229.dyn.iinet.net.au] has left #periperi-io ["Leaving"] +10:04 -!- horms [~horms@124-171-1-229.dyn.iinet.net.au] has joined #periperi-io +10:05 < geertu> I've got SCIF RTS/CTS hardware assisted flow control working. +10:05 < wsa_> so, no io base contract for you but additional task SCIF FIFO flushing for May +10:05 < wsa_> cool +10:06 < wsa_> wasn't that scheduled for June? :) +10:06 < geertu> So far tested on Koelsch with HSCIF and SCIFB.

I hope to make an early start on that one. So far I'm planning to prototype on Gen2 assuming I can get documentation for a Gen2 Soc. +10:39 < horms> There is support for this feature in the BSP, including enabling the SCC which seems to be the core of the task. +10:39 < wsa_> Yes, Gen2 should be prototyped, we still don't have Gen3 DMA support yet +10:39 < wsa_> upstream that is +10:39 < horms> My basic plan is to rework the BSP code and see how far that gets us. +10:40 < horms> I have not looked in enough detail to have any problems yet :) +10:40 < wsa_> i saw some custom DT bindings in there IIRC +10:41 < wsa_> i would wonder if they are really needed or if the mmc core doesn't have a solution for them already somewhere +10:41 < horms> I would also like to mention that Kaneko-san has been working on isolating which BSP v3.2.0 patches look good for upstream. I am encouraging him to discuss individial patches on the periperi ML. Presumably some will relate to IO. +10:41 < horms> thanks. obviously custom bindings are a red flashing light. +10:41 < wsa_> :) +10:42 < horms> possibly the base addr for the SCC needs to be specified in DT +10:42 < wsa_> OK, awaiting Kaneko-sans patches then +10:42 < horms> again, I haven't looked very far yet +10:43 < horms> If there are any priorities for upporting let me know. But more likely we'll be feeding features into your todo list +10:43 < wsa_> yes, i think so, too +10:43 < horms> ok, that was all i had in mind to say +10:43 < horms> perhaps we can move on? +10:44 < wsa_> when is the next BSP release planned BTW? +10:44 < wsa_> would be nice to know +10:44 < horms> there was a release, 3.2.1 very recently +10:44 < horms> like a last week +10:44 < horms> morimoto-san or shimoda-san likely have more insight into the timing of the next release than I +10:44 < neg> there where new code ind the bsp from ~friday I think +10:45 < wsa_> thanks, will check +10:45 < horms> The 3.2.1 release, at a glance, seems to have a lot of M3 related changes +10:45 < geertu> Yeah, CPG and PFC +10:45 < wsa_> uli___ is next +10:45 < geertu> (noticed that earlier this week) +10:47 <@uli___> no additional i/o tasks for me so far +10:47 < wsa_> he has a 5 days/quarter base contract for IO and does CANFD driver review and r8a7740 clock driver refactoring to fix an SDHI regression. The latter one most probably in June. +10:47 < wsa_> and no IO additional tasks in May +10:47 < wsa_> correct? +10:47 <@uli___> yes +10:48 < wsa_> but most likely additional tasks in June (like with geertu and simon, too; not sure about niklas, we will see then) +10:49 < wsa_> uli___: did you have time to check the CANFD driver yet? +10:49 < horms> fwiw i have no insight into my bonus plans in June :) +10:49 <@uli___> on screen now, but haven't looked closely yet +10:49 < wsa_> horms: from what I know, 1 week for IO is planned +10:50 < horms> thanks, good to know :) +10:51 < wsa_> the CANFD driver seems stuck; I hope that additional comments or simply "reviewed-by" tags will get it rolling again +10:51 < wsa_> i don't think it is that bad, it has a few iterations done already +10:52 <@uli___> ramesh asked whether to send a new version 2 weeks ago, to no response +10:52 < horms> possibly the person responsible got re-tasked +10:53 < wsa_> "I can send a next version of patch if we have a closure on current set of comments. +10:53 < horms> ok then perhaps he just needs some feedback +10:53 < wsa_> " +10:53 < wsa_> he said +10:53 < horms> Is there closure? +10:53 < wsa_> uli___: maybe you can agree/disagree to his comments to re-start the procedure +10:54 <@uli___> i can say "please send it, i'd like to have a look"... +10:54 < wsa_> that might work, too +10:54 < wsa_> :) +10:55 < wsa_> unless you see something worth fixing already +10:56 < wsa_> ok, but you are at it +10:56 <@uli___> i am +10:56 < wsa_> so, it is my turn now +10:57 < wsa_> i have a base contract of 5 days/month for IO currently +10:57 < wsa_> this month was nearly completely eaten up by the new task/contract procedures +10:57 < wsa_> i hope this will become better once things settled down +10:58 < geertu> :-) +10:58 < wsa_> my plan is to keep this time for a) group leading and b) spontaneous, important, emergency tasks in the IO sector +10:59 < wsa_> my additional tasks for May are "pre-timeout support for watchdog" and "SDIO support on Gen3 for SDHI" +11:00 < horms> wsa_: do you have any SDIO cards? +11:00 < wsa_> yes +11:00 < horms> great! +11:01 < wsa_> Bluetooth, and serial (GPS) and a wireless one +11:01 < wsa_> sadly the latter is not supported by Linux :( +11:01 < horms> I have one SDIO wifi card that is known to work (in the past at least) with renesas hw. I can lend it to you / let you know the model if that would help. +11:01 < wsa_> i ordered a 802.11ac card to test UHS throughput with SDIO +11:02 < wsa_> but this card is still in prototype stage and I dunno when I'll get it :/ +11:02 < wsa_> horms: that would in deed help +11:03 < horms> ok, great. I probably can't get my hands on the card for about 10 days (because I am not in Japan).

I saw that Morimoto-san reported an issue of Audio driver. +10:09 < geertu> khiem: That was an issue with v4 of the series, which caused probe deferral of the DMA controllers +10:09 < morimoto> does it be solved on v5 ? +10:10 < geertu> Yes, v6 (which was applied) doesn't have this problem +10:10 < morimoto> OK, nice ! +10:10 < horms> I have queued up the changes. We are yet to see if the arm-soc team accepts them. But Arnd seems to be in a good mood this week. So hopefully things will progress smoothly. +10:11 < geertu> Good. +10:11 < geertu> Isn't Arnd ususally in a good mood w.r.t. merging? +10:12 < geertu> I guess Niklas is still waiting for Olof... +10:12 < khiemnguyen> geertu:: have you tested with some drivers using power domain like A3VP ? +10:12 < horms> My feeling is that Olof can be a bit more prickly with regards to merging. +10:12 < geertu> khiem: A3VP is turned on when e.g. reading from /dev/video0 +10:12 < neg> Yes I have not heard anything back from Olof, anyone have a feel of what he is thinking? +10:12 < horms> geertu: it is possible that I worry too much :) +10:12 < pinchartl> khiemnguyen: I've tested power domains with the VSP driver +10:13 < geertu> Probably he doesn't have an answer... +10:13 < geertu> Arnd is much more familiar with DMA +10:13 < horms> neg: perhaps you could ping Arnd somehow? +10:14 < geertu> Arnd definitely knows how the function to retrieve dmas from DT works. +10:14 < neg> horms: sure, I can send a ping to Arnd and ask his opinion on the patches +10:14 < horms> neg: that would be great, thanks +10:15 < neg> There where some comments that it was a bit silly to do it in so many patches, maybe i can squash them as one per SoC and resend and at the same time ask Arnd for his input? +10:15 < horms> Personally I'm fine with many patches. But squashing them as you suggest may make things a bit more managable. +10:16 < neg> I'm fine anyway, I only did lots of patches since it seemed like it was the way it was done in the past +10:17 < horms> possibly that was because patches were done over time. though possibly all applied in a bunch +10:17 < horms> anyway, i don't think the number of patches is the core issue +10:17 < geertu> Maintainer preference about granularity of patches may differ a lot... +10:17 < neg> OK, I will squash and resend +10:18 < horms> this maintainer is ok with that :) +10:18 < geertu> Best ask Arnd first, before squashing and resending +10:19 < neg> OK then I will ping Arnd asking his opinin and if he wants it reposted squashed +10:20 < geertu> Good, thx! +10:23 < neg> I also might have to rethink part of my IPMMU+DMAC parches, Christoph Hellwig have a point I use dma_mapping_error() which uses the debug_dma_* so I might need another way of signaling mapping error +10:23 < pinchartl> or maybe we could make debug_dma_* safe with resource DMA mappings ? +10:24 < neg> That would be a good solution yes +10:25 < neg> Will look into it +10:27 < neg> I was thinkig maybe to add a using check pfn_valid(pfn) and not call debug_dma_* from dma_mapping_error, or is that a bad idea? +10:28 < pinchartl> that seems like a bit of a hack +10:28 < pinchartl> but I don't know what else would be possible +10:30 < pinchartl> how about starting by checking the debug_dma_* call paths, and see which calls can be problematic with resources ? +10:30 < pinchartl> obviously ignoring the ones that can't be used with resources +10:31 < pinchartl> it looks like the core issue is the phys_addr() function +10:32 < pinchartl> if you add a dma_debug_resource type, you could special-case phys_addr() +10:32 < neg> that would be a better solution yes, I will have a look and se if I can figure it out +10:32 < pinchartl> and possibly return (entry->pfn << PAGE_SHIFT) + entry->offset +10:33 < pinchartl> it's just a very rough first analysis, there could be other issues +10:33 < pinchartl> but I think that's at least a good path to investigate +10:34 < neg> I agree, will do +10:36 < pinchartl> geertu: are you asleep ? :-) +10:36 < geertu> No +10:37 < geertu> Just waiting for your discussion to finish +10:37 < geertu> Any other Upcoming Gen3 development? +10:37 < horms> M3 +10:37 < horms> I plan to add basic support for M3, most likely based on what is in BSP v3.2.1, by the end of June. I am yet to make a start on this. +10:37 < geertu> dammsan should have M3 in his board farm soon, IIUC? +10:37 < dammsan> later this week +10:38 < geertu> And I'm gonna do CPG/MSSR and SYSC +10:38 < horms> superb +10:38 < horms> ok, it sounds like we will have to tag-team a bit +10:38 < horms> both for board access +10:38 < horms> and dependencies on each other +10:40 < geertu> Sure. We managed to do that before +10:40 * geertu notices the marzen semaphore in the topic line +10:41 < horms> yes, that may be a stale lock +10:41 < geertu> It's been a while I used the lock. Usually I just look at the marzen power state... +10:42 < geertu> But for M3 we'll have to be more strict again +10:43 < geertu> Any other Upcoming Gen3 development? +10:46 < geertu> Topic 2. Reserved memory for AXI decompression area +10:46 < geertu> shimoda-san: Can you explain a bit, please? +10:46 < shimoda> yes +10:47 < shimoda> Gen3 has specific HW IP in "14. AXI-BUS" +10:48 < shimoda> the IP will decompress memory when software writes data +10:49 < shimoda> So, if a software start the IP, other software (e.g. linux) must not use such area +10:49 < shimoda> about the detail, please look at an email that I sent :) +10:50 < shimoda> and then, I would like to discuss how to manage this on linux kernel +10:50 < geertu> All of this is determined by the firmware, right? +10:50 < shimoda> geertu: right +10:51 < geertu> Then I think the firmware should reserve the memory in the DTB it passes to the kernel +10:52 < shimoda> I see. The latest Gen3 BSP will do so. however, morimoto-san and magnus-san don't prefer it :) +10:53 < geertu> Does the BSP have the reserved area in the DTS, or does the bootloader modify the DTB? +10:53 < shimoda> oops, BSP has a specific DTS, no bootloader modify the DTB +10:53 < shimoda> sorry, I misunderstood your suggestion +10:54 < geertu> I think it's similar to how the bootloader modifies the DTB to pass the bootargs +10:54 < pinchartl> geertu: I agree, if the bootloader reserves memory for firmware usage, it should modify the DTB +10:55 < dammsan> i suspect that different firmware components are responsible for different things +10:55 < dammsan> so IPL may program the AXI +10:55 < dammsan> while U-boot is supposed to modify the DTB if I understand you guys correctly +10:55 < geertu> Yes +10:56 < dammsan> so the problem how to pass base registers between components still exists +10:56 < geertu> True. +10:56 < dammsan> i mean memory window parameters +10:57 < khiemnguyen> so, for upstream kernel, we should disable that feature ? +10:57 < geertu> Well, DT is supposed to describe the hardware +10:57 < geertu> Hence if some memory is unusable, it should say so. +10:57 < khiemnguyen> that feature is optional. +10:58 < geertu> "Non-Secure software (U-Boot/Linux) cannot access these registers" +10:58 < geertu> So as soon as the IPL implements protection, U-Boot/Linux cano no longer find out where the reserved area is? +10:59 < geertu> s/cano/can/ +10:59 < khiemnguyen> in future, we can get the information via OP-TEE call. But it has not been implemented yet. Just planning. +11:00 < morimoto> geertu: can I confirm ? +11:00 < shimoda> khiemnguyen: i see. +11:00 < morimoto> it will be implemented from v2.8.0 firmware. it is not yet implemented on v2.7.0. +11:01 < dammsan> i think we should ask IPL people to program version number in a specific location for read-only use +11:01 -!- khiemnguyen [d2a0fca9@gateway/web/cgi-irc/kiwiirc.com/ip.210.160.252.169] has quit [Quit: http://www.kiwiirc.com/ - A hand crafted IRC client] +11:01 < morimoto> Do you mean it can be controlled by u-boot ? +11:01 -!- khiemnguyen [d2a0fca9@gateway/web/cgi-irc/kiwiirc.com/ip.210.160.252.169] has joined #periperi +11:01 < dammsan> like for instance MFIBTSTSR register +11:01 < geertu> morimoto: confirm what? +11:01 < morimoto> dammsan: it can be 1 solution +11:02 < dammsan> morimoto: yes +11:02 < morimoto> geertu: your opinion is uboot can control it ? (v2.7.0 / v2.8.0 etc) +11:03 < geertu> morimoto: That sounds like the logical place to me. +11:04 < geertu> How uboot obtains the knowledge is another question... +11:04 < morimoto> I wounder does it mean we need updated uboot ? +11:05 < geertu> I think so +11:06 < khiemnguyen> geertu: You want updated uboot to control memory decompress, right ? +11:06 < morimoto> This means, if people has old uboot, but use new kernel, it will... ? +11:06 < geertu> Go bang +11:07 < morimoto> This v2.8.0 firmware will sets its start address and size on specific area. Can kernel use it and reserve ? +11:07 < morimoto> inside kernel. +11:07 < geertu> khiemnguyen: No, if memory decompress is enabled, U-boot should tell the kernel by adding the reserved area to the DTB +11:07 < morimoto> then, old uboot is no issue +11:08 < geertu> If there's a reliable way for the kernel to find out, yes. +11:08 < dammsan> seems we need a short term and a long term solution really +11:08 < dammsan> regardless IPL need to be able to expose functionality +11:09 < dammsan> which may be the same reliable way as geertu is aksing about +11:09 < geertu> Yes.

And they put low priority on this item. +11:30 < horms> khiemnguyen: thanks, got it +11:30 < khiemnguyen> In the meantime, I think they focus on M3 support and implement new System Suspend-to-RAM operation mode. +11:31 < geertu> With v270, s2ram no longer fails with an error, but the system suspends, immediately resumes, and afterwards NFS fails (no more interrupts?). +11:32 < geertu> So that's actually a regression, as before trying s2ram didn't make the system unusable. +11:32 < dammsan> i would prefer if bugs were fixed before features were added +11:32 < geertu> True. +11:32 < dammsan> but i'm just a grumpy old man +11:33 < geertu> The same for trying to unplug CPU0: before it failed with an error, now it locks up the system. +11:33 < khiemnguyen> geertu: NFS fails, it seems ethernet driver has not handle s2ram well. +11:33 < geertu> khiemnguyen: That's another possibility. +11:34 < khiemnguyen> I meant suspend/resume callbacks in ethernet driver. +11:34 < dammsan> khiemnguyen: are you aware of any roadmap for firmware features? +11:34 * pinchartl has to run +11:34 < pinchartl> I'm late for my lunch time meeting +11:35 < geertu> pinchartl: Bye, thx for joining! +11:35 < khiemnguyen> dammsan: the roadmap is changing rapidly... +11:36 < dammsan> khiemnguyen: that may cause problems for everyone +11:36 < pinchartl> ping me this afternoon if you have any question for me +11:36 < dammsan> it would be nice to improve the situation somehow +11:37 < khiemnguyen> I think so too. Sometimes, the bottleneck is in secure firmware support. +11:38 < khiemnguyen> We have not encountered this in Gen2, but Gen3 use secure firmware, as universal solution for ARMv8. +11:38 < khiemnguyen> I guess developers for other SoC platform also have same issues. +11:38 < dammsan> must be +11:39 < khiemnguyen> we have to accept it, right ? :) +11:39 < dammsan> i think we have to improve the situation =) +11:39 < dammsan> i wonder if we can arrange some f2f meeting inside renesas to request more clear feature prediction? +11:41 < horms> +1 +11:41 < dammsan> anyway, scope is outside this meeting space +11:41 < dammsan> i think we can build leverage by not merging soem features in upstream and request help from superiors +11:42 < dammsan> so lets keep upstream M3 support minimal please +11:42 < horms> dammsan: lets have a f2f meeting about that :) +11:42 < dammsan> sure +11:43 < geertu> dammsan: One problem is that we didn't do anything for e.g. s2ram. +11:43 < geertu> dammsan: If the firmware advertises it's available, it can be used/ +11:43 < dammsan> geertu: that's fine, its an incremental thing +11:44 < dammsan> we can't opt-out by default? +11:44 < geertu> dammsan: If hot-unplugging cpu0 suddenly locks the system instead of reporting an error, there's nothing we can do in the kernel. +11:44 < geertu> I don't think so. +11:44 < dammsan> that's why we should only enable it when we know it is working +11:44 < geertu> PSCI is enabled by default on arm64. +11:44 < dammsan> right +11:45 < dammsan> if we could retrieve firmware version somehow we could disable certain things during run time +11:46 < geertu> The good news is that restart works now (with v270). +11:47 < geertu> We got flamed by Mark Rutland that it didn't work in v230, as that version was not PSCI-compliant. +11:47 < geertu> But there's nothing the kernel did to make that work or not work. +11:48 < dammsan> it is just the cpu node integration order +11:48 < geertu> "trusted" means "it's something you have to trust" (because you have no choice) +11:48 < dammsan> apart from that nothing i agree +11:49 < dammsan> it would be good to have certain features documented though +11:49 < geertu> Time to conclude? +11:49 < dammsan> sure +11:49 < geertu> Thanks for joining, and CU! +11:50 < horms> bye +11:50 < shimoda> thanks, bye! +11:50 < uli___> bye +11:50 < neg> bye all, thanks +11:50 < dammsan> thanks +11:50 < khiemnguyen> bye diff --git a/wiki/Chat_log/20160510-core-chatlog b/wiki/Chat_log/20160510-core-chatlog new file mode 100644 index 0000000..8199e5c --- /dev/null +++ b/wiki/Chat_log/20160510-core-chatlog @@ -0,0 +1,238 @@ +Core-chat-meeting-2016-05-10 + +10:07 < geertu> Agenda: +10:07 < geertu> 1.

He should be here soon. +10:17 -!- dammsan [~dammsan@s214090.ppp.asahi-net.or.jp] has joined #periperi +10:17 < horms> voila! +10:17 < geertu> Welcome dammsan +10:17 < dammsan> thanks, sorry about the delay. +10:18 < geertu> We've just discussed the noise in your house ;-) +10:18 < dammsan> also, sorry for trouble with the remote access - the cat shut down my house +10:18 < dammsan> but it is up and running now again +10:18 < geertu> You use the cat for remote access (flipping switches and pressing buttons)? Cool! +10:19 < morimoto> Ohh loo-chan ! +10:19 < dammsan> it manages things by itself somehow =) +10:20 < dammsan> 20 vms got powered off =) +10:20 < geertu> Oops. that includes the locally installed tftp servers? +10:20 < dammsan> geertu: so your local tftp setup is probably gone +10:20 < dammsan> yeah - sorry!! +10:20 < dammsan> i restarted but lost state +10:20 < geertu> NP, time to automate the install from my side +10:21 < dammsan> thanks for covering +10:22 < geertu> Any other upcoming Gen3 development for the Core group? +10:23 < dammsan> i guess PFC paper work for ulrich needs to be finalised +10:24 < dammsan> apart from that nothing from my side +10:24 < neg> I would like to do something for the core group within the next month or so :-) +10:24 < uli___> dammsan: from my side, there is no rush, i'll soon be gone, back on the 23rd +10:25 < geertu> neg: DMA? +10:25 < dammsan> uli___: ok, thanks for letting me know. we should finalise all your tasks rather soon then to wrap up 6/E tasks +10:25 < horms> dammsan: uli___: what is the nature of the pfc work? +10:26 < neg> geertu: I sent out refreshed IPMMU+DMAC patches yesterday so I have no task in the pipeline to work on +10:26 < dammsan> uli___: can you talk to the group leaders and decide how to split your remaining time between the groups? +10:26 < uli___> horms: r8a7795 bias support and minimal r8a7796 support +10:26 < uli___> dammsan: i have two core and one multimedia task, so i'm left with one slot +10:27 < uli___> which is supposed to be i/o, i guess +10:27 < horms> uli___: thanks. i will skip doing pfc as part of my basic r8a7796 support +10:29 < dammsan> uli___: can you send an email to me and the group leaders with a list of the additional tasks you have signed for and what is planned as well as what is left? +10:29 < uli___> ok +10:30 < dammsan> thanks +10:30 < dammsan> geertu: do you feel satisfied with the amount of additional slots you got for the core group? +10:30 < geertu> ;-) +10:31 < dammsan> geertu: or would you like to try to steal some time if something is urgent? =) +10:31 < horms> fwiw, i think i have one free slot +10:31 < dammsan> in my mind core group assignment is more or less done (with the exception of uli) +10:31 < dammsan> so the remainer of the slots go to i/o and multimedia +10:32 < dammsan> but we can adjust depending on the need +10:32 < dammsan> horms: i think you have more than one slot left +10:33 < horms> ok, lets talk about that some time +10:33 < dammsan> sure +10:36 < khiemnguyen> up up +10:37 < geertu> Topic 2. Increasing the size of GIC-400 mapped registers +10:37 < geertu> I had a look at the actual register contents earlier this morning +10:37 < geertu> and increasing region 1 and 3 to 128 KiB doesn't make much sense to me (64 KiB is OK). +10:38 < geertu> Region 0 is 1 4 KiB page (16 times aliased in the full 64 KiB block) +10:38 < pinchartl> geertu: didn't Marc explain that the register block is aliased multiple times over a 128kB region ? +10:38 < horms> yes +10:38 < geertu> pinchartl: That's true for region 2 +10:38 < dammsan> geertu: shouldn't xen do whatever magic is needed to make it fit? +10:38 < dammsan> and we are just describing the hardware in DT? +10:39 < horms> dammsan: that is my basic feeling too +10:39 < horms> but it seems that Mark Zyngnier has taken the kernel implementation in a different direction +10:39 < geertu> Region 1 is currently 2 identical 4 KiB pages +10:39 < geertu> Dirk wants to expand it to 128 KiB. +10:40 < geertu> However, the first 64 KiB is just 16 aliases of the first (and second) 4 KiB page +10:40 < geertu> While the second 64 KiB is all zeroes +10:40 < geertu> Region 2 is already 128 KiB, which makes sense, as it's 16 aliased pages + 16 different aliased pages +10:41 < geertu> For region 3, the other one Dirk wants to increase, the situatin is identical to region 1 +10:42 < dammsan> geertu: i recall the gic behaving differently depending on if secure mode is used or not +10:42 < dammsan> there is some bit that can be used to determine which mode is used +10:42 < dammsan> (at least in some version of the gic) +10:42 < horms> It seems to me that at some level ARM decided that this aliasing approach is the solution to allowing hypervisors with 64Kb pages to trap the areas in question +10:42 < geertu> So region 1 and region 2 have 2 all-zero blocks due to non-secure mode? +10:43 < dammsan> geertu: not sure, but it could be so +10:43 < dammsan> feel free to try to convince me to install the old secure mode environment +10:44 < geertu> Then 128 KiB for region 1 and 3 make sense. +10:44 < geertu> And the question is more like why we had 8 KiB there before (copied from Gen2?) +10:45 < geertu> I'll respond to the email thread +10:45 < dammsan> i think it is possible to use the SCIF download mode and enter via JTAG to access secure mode +10:45 < horms> Presumably it was copied either from Gen2 or from the BSP (which may be the same thing) +10:45 < geertu> But if the patch was OK in the first place, why didn't Marc just provide his Acked-by? +10:45 < horms> I think Mark came into the thread pretty lated +10:45 < horms> and the patch itself had disappeared from view by then +10:46 < horms> s/lated/late/ +10:46 < geertu> I checked, and it was still quoted +10:46 < dammsan> so may i ask, the base addresses remain unchanged +10:46 < dammsan> this is just about the size? +10:46 < horms> yes +10:46 < dammsan> ok thanks +10:46 < geertu> dammsan: The driver will adjust the size +10:46 < geertu> dammsan: The driver will adjust the base address +10:47 < dammsan> that would make sense +10:47 < horms> I don't think it would be unreasonable to ask Mark for an Ack. It does seem to be an area he is knoledgable about +10:47 < geertu> The driver needs 2 contiguous 4 KiB blocks +10:47 < geertu> So if 2 64 KiB blocks are given, it uses register base = block base + 60 KiB +10:47 < dammsan> but it could be optimized with 64 KiB blocks +10:48 < geertu> optimized? +10:48 < dammsan> fewer entries in the TLB? +10:48 < geertu> The idea is that the 2 4 KiB register blocks are in different pages +10:48 < geertu> so they can have different protection +10:48 < dammsan> ok ok gotcha, cpu interface and distributor +10:48 < dammsan> never mind me +10:49 < dammsan> makes sense +10:49 < horms> geertu: can you talk to dirk/mark a bit about this? basically I feel it is ok to apply the patch. but I'd rather not live to regret it. +10:50 < geertu> horms: yes, that's what I said I will do +10:50 < horms> excellent, thanks! +10:50 < geertu> Topic 3. Face-2-face meeting during LinuxCon Japan +10:52 < morimoto> Now I'm collecting topics from Renesas member +10:52 < morimoto> Oops, sorry it is for RenesasCon +10:54 < morimoto> I think we can have Mini-PeriCon on 11th, and RenesasCon 12th +10:54 < geertu> I think the topic is about all meetings during that week +10:56 < morimoto> I wounder does Ulich come to Japan ? +10:57 < horms> uli___: ↑ +10:57 < uli___> no, i won't :( +10:58 < morimoto> OK +10:59 < morimoto> I will post collected Renesas side topic to PeriPeriML +10:59 < geertu> OK +11:00 < morimoto> Your side would like to know R-Car business, and each member/group +11:00 < morimoto> is this correct ? +11:01 < geertu> I think so +11:01 < neg> At least I would like that +11:01 < khiemnguyen> Where will we have the meeting ? +11:01 < morimoto> About RenesasCon, I'm planing on Renesas office +11:02 < morimoto> but the conference room is not yet decided +11:02 < pinchartl> on what day would that be ? +11:02 < morimoto> RenesasCon = 12th +11:02 < horms> morimoto: that would be the Musashi-works near Kokubunji? +11:02 < morimoto> Yes +11:03 < horms> Got it +11:03 < morimoto> Because Renesas member will join +11:03 < pinchartl> ok +11:03 < morimoto> We can have different place for MiniPeriCon (?) +11:04 < morimoto> Then, we (= Renesas) would like to know your side current tasks/issue/headache +11:04 < horms> I mainly ask because althouth I know where it is other may not. Its a bit of a distance from e.g. where LinuxCon is being held. They probably need to plan for that. +11:04 < morimoto> Please create something of presentation :) +11:05 < khiemnguyen> each group leader will make presentation ? +11:05 < morimoto> horms: Yes, it is my headache too +11:05 < geertu> It's about one hour from LinuxCon? +11:06 < horms> I am happy to help people find the venue :) +11:06 < horms> geertu: perhaps a little more. +11:07 < horms> google says about an hour, you were right +11:08 * geertu used Google +11:08 < horms> :) +11:08 < neg> have anyone booked hotell? My knowledge about Toky is nil and I don't want to live on the wrong side of the tracks :-) +11:09 < horms> google can help you :) +11:09 < morimoto> Or I can :) +11:09 < morimoto> dammsan: do you have any plan for MiniPeriCon room ? +11:10 < pinchartl> neg: I've booked at the conference hotel +11:10 < horms> morimoto: (off topic) do you know if the BSP meeting on friday is still on? +11:10 < neg> horms: I tried google for Brussels and ended up in a hotel where they probobly are used to charge you by the hour +11:11 < morimoto> horms: for this week 13th? then yes, still ON +11:11 < horms> haha. i can help too +11:11 < horms> morimoto: 了解です +11:11 < dammsan> morimoto: no plan, the library actually just called me and said I owed the the double about of money due to a no-show meeting room =) +11:12 < geertu> pinchartl: it seems to be fully booked by now +11:13 < geertu> neg: Good for you! Usually people don't stay an integer number of 24h-days +11:14 < neg> geertu: :-) +11:15 < horms> fwiw, i usually stay either at the monteray n +11:15 < horms> hanzomon or somewhere in kudanshita for linuxcon +11:15 < horms> partly because that is in between linuxcon and the old renesas office +11:15 < horms> and i'm not affraid of the subway system :) +11:16 < dammsan> i recommend the "la festa kichijouji" hotel for everyone =) +11:17 < morimoto> closed to your home +11:18 < dammsan> you can probably both rest and stay if you want +11:18 < geertu> Doesn't look like it's close to LinuxCon? +11:18 < horms> its close to renesas :) +11:18 < dammsan> its not, i'm not serious +11:19 < horms> Somewhere on the Tozai line might be a good choice. As that can be used to get both to LinuxCon and part way to Renesas +11:19 < geertu> Be careful with such jokes, or we'll all end up in little tubes near Fukushima ;-) +11:19 < dammsan> =) +11:19 < horms> Or Idabashi which is within walking distance of LinuxCon and should connect to the Sobu/Chuo line to head out to Renesas +11:20 < geertu> Idabashi is not a hotel? +11:20 < horms> its an area +11:21 < horms> presumably there are hotels there +11:21 < geertu> horms: OK, I'll ask neg to find a good one over there ;-) +11:21 < horms> i'm unsure if my family will join me or not +11:21 < horms> so i will be holding off on a booking for now +11:22 < neg> geertu: I will find a nice one, how many hours do you need :-) +11:23 < horms> Probably geertu only needs a rest every second day +11:24 < geertu> Topic 4. Status check for tasks from last meeting - what is remaining? +11:25 < geertu> r8a7796 CPG/MSSR and SYSC is public +11:25 < neg> I have pinged Arnd in the thread for the multiple DT DMACs but no reply so far, plan to wait a few more days and ping again +11:26 < geertu> r8a7795 drive-strength support is merged +11:26 < khiemnguyen> I sent out CPUfreq patches.

I'm referring to the patches Olof took exception to +11:29 < neg> horms: as we talked about during last meeting I would try to get Arnds feedback on the same patches but I have failed to get his attention +11:30 < horms> ok +11:30 < pinchartl> I have to go I'm afraid +11:30 < horms> bye +11:30 < morimoto> pinchartl: quick request +11:31 < morimoto> pinchartl: Kurokawa-san is waiting your resonse +11:31 < morimoto> s/resonse/response/ +11:31 < dammsan> morimoto: lets discuss this f2f tomororw +11:31 < morimoto> OK +11:32 < pinchartl> morimoto: I'll reply this afternoon +11:32 < pinchartl> I was away last week +11:32 < morimoto> Thanks +11:32 < pinchartl> and catching up with my e-mails +11:33 < pinchartl> have a nice afternoon/evening +11:34 -!- khiemnguyen [d2a0fca8@gateway/web/cgi-irc/kiwiirc.com/ip.210.160.252.168] has quit [Quit: http://www.kiwiirc.com/ - A hand crafted IRC client] +11:34 -!- khiemnguyen [d2a0fca8@gateway/web/cgi-irc/kiwiirc.com/ip.210.160.252.168] has joined #periperi +11:35 < geertu> I think all topics have been covered. +11:35 < geertu> Or did I miss anything? +11:35 < geertu> pinchartl: Bye! +11:35 < dammsan> geertu: thanks for your help +11:36 < horms> nothing from my side +11:36 < geertu> pinchartl: What happened to git.linuxtv.org?

But if you have something small need doing I can try to squeeze it in +10:44 < wsa_> ok +10:44 < wsa_> yeah, i asked because of distribution of small things (if there is one) +10:44 < wsa_> wanted to know where we are +10:45 < wsa_> but since we fixed the r8a7740 SDHI regression, I don't see anything left there +10:45 <@neg> ofc, if you think of something let me know and I see what I can do +10:45 < wsa_> please speak up if i am wrong +10:46 < wsa_> so, neg is basically done with IO for Q2 and will (probably) have some more days in Q3 +10:47 < wsa_> so, ulrich is not here and will do the CAN driver review once he is back +10:47 < wsa_> morimoto-san is also not here but doesn't have any tasks assigned anyhow +10:48 < wsa_> so, in general i think we are on track +10:48 < wsa_> thanks guys! +10:48 < wsa_> it would be nice to have more IO time for geert, though +10:48 < shimoda> thank you! +10:50 < wsa_> ok, anything more to discuss? +10:50 <@neg> If task list is done I have a IO question +10:50 < wsa_> sure +10:51 <@neg> during boot of Salvator-X it is deleayed for ~20 sec and then i get this 'xhci-hcd ee000000.usb: can't setup: -110' +10:51 <@neg> i use the arm64_defconfig and was just wondering if this is known +10:51 < shimoda> oh, sorry it's xhci driver problem +10:52 < wsa_> there are mails about it on renesas-soc +10:52 <@neg> ok thanks +10:53 < wsa_> in short: a Kconfig dependecy needs to be set up +10:53 < shimoda> in v4.6, it should be fixed by f879fc32aa0c96fbac261b3d857a1239d554ad01 +10:54 <@neg> shimoda: great, thanks +10:55 < shimoda> neg: you're welcome! +11:04 < wsa_> ok, if no more questions... +11:04 < wsa_> ...then thanks for this meeting! +11:05 < shimoda> thank you! bye! +11:05 <@neg> thanks all +11:05 -!- shimoda [~shimoda@relprex3.renesas.com] has quit Quit: WeeChat 0.4.2 +11:06 < geertu> Data collection phase ;-)bye +11:06 < wsa_> good luck geertu ! +11:06 < geertu> Seems I have a problem with my IRC FIFO, too ;-) +--- Log closed Thu May 19 11:16:26 2016 diff --git a/wiki/Chat_log/20160524-core-chatlog b/wiki/Chat_log/20160524-core-chatlog new file mode 100644 index 0000000..de77a2c --- /dev/null +++ b/wiki/Chat_log/20160524-core-chatlog @@ -0,0 +1,255 @@ +Core-chat-meeting-2016-05-24 + +10:02 < geertu> Welcome to today's Core Group Chat Meeting +10:02 < geertu> Laurent will join later +10:02 < geertu> Magnus will have a fluctuating presence +10:03 < morimoto> I will quit 1hour later +10:03 < geertu> Agenda: +10:03 < geertu> 1.

Upcoming Gen3 development for the Core group +10:04 < geertu> Any takers? +10:04 < horms> I have a few things to mention +10:05 < geertu> Please go ahead +10:06 < horms> Kaneko-san has been working on classifing the patches present in the v3.2.x BSP. v3.2.1 is mostly done. I can share what we have so far if it is of interest to the group. Mainly it covers r8a7795. And probaly we can tease some new tasks out of that. +10:06 < geertu> ok +10:06 < horms> I have asked him to start looking over the v3.2.3 BSP. I expect that to include rather a lot of r8a7796 code when compared to v3.2.1 +10:07 < horms> I mainly raise this because I'm not entirely sure how to make the information available here. Or indeed if it is of much interest at all. +10:08 < geertu> As this affects all groups, perhaps it should be emailed to periperi instead? +10:08 < horms> That is all I have to raise for this topic. +10:08 < shimoda> horms: perhaps, you mean v3.2.2 BSP, not v3.2.3 :) +10:09 < horms> Sorry, I mixed up the versions. +10:09 < horms> We have looked over v3.2.0. +10:09 < horms> We are starting to look over v3.2.2. +10:10 < horms> There is also a v3.2.1 but we are planning to skip from v3.2.0 to v3.2.2. +10:10 < horms> geertu: sure, good suggestion. +10:11 < shimoda> I agree with geert-san. this topic is related to all groups. and I would like to share information about bsp sdhi driver later :) +10:12 < shimoda> because the bsp sdhi driver has some workaround code, and i don't think we upport it +10:13 < horms> Ok. I'll make the raw information I have available on periperi ML. And we can decide what are some good next steps there. +10:14 < shimoda> thanks! +10:14 < horms> off topic. but I would value any insights/testing of timeouts during tuning in my sdr104 patch set. +10:14 < khiemnguyen> horms: Please add me to periperi ML. +10:15 < horms> khiemnguyen: I will send the BSP analys there. Is that what you were requesting? +10:15 < khiemnguyen> horms: I just wonder whether my email address is included or not :) +10:16 < horms> I can fix that. Lets discuss in private. +10:16 < horms> geertu: I think we cam move on +10:17 < geertu> Yes. any more upcoming development? +10:17 < geertu> I'm mostly fighting^H^H^H^H^H^H^H^Hbusy with my IO task right now +10:18 < horms> Oh, sorry. There is one more thing I thought of. +10:18 < horms> Sharing DT betweek Gen3 SoCs. Dirk raised this on the ML. +10:18 < horms> It seems like a good idea in principle. +10:19 < horms> But it doesn't seem to work well with our per-soc compatibility strings. +10:19 < geertu> Indeed +10:19 < horms> So I wonder if the number of nodes that can be shared via an #include scheme is quite small +10:19 < geertu> But nothing some smart (obfuscated?) cpp macros can't solve... +10:19 < horms> I was thinking of responding along those lines. +10:19 < horms> Basically if we can come up with a scheme that is great. +10:20 < horms> But I'm inclined to think that is an effort to be done in parallel +10:20 < horms> rather than a dependency for adding M3-W +10:20 < geertu> Yes, in parallel, not as a dependency +10:20 < horms> Ok, I'll respond unless you wish to (I won't get to it until at least tomorrow) +10:21 < geertu> OK, will see whether I find some time to write a reply. +10:22 < horms> Thanks +10:22 < horms> khiemnguyen: you are now subscribed to the periperi ML +10:25 < horms> geertu: shall we move on? +10:25 < geertu> yes please +10:26 < horms> I guess its mode pin time :) +10:26 < geertu> Yeah, again! +10:26 < horms> But perhaps we should defer that to after Laurent arrives_ +10:26 < horms> ? +10:26 < geertu> Indeed.

Status check for tasks from last meeting - what is remaining? +10:30 < geertu> We have a few tasks with deadline v4.6 in core/todo +10:31 < geertu> IPMMU,v4.6,plan,niklas,Discuss API changes on the dma-engine mailing list +10:31 < geertu> neg: I assume this is now completed? +10:32 < neg> yes +10:32 < neg> or sorry. no +10:33 < geertu> I'll uodate it for v4.7? +10:33 < geertu> s/uodate/update/ +10:34 < neg> thanks.

Any test cases to confirm SYS-DMAC2 ? +10:49 < geertu> khiemnguyen: If you change (both) dmac1 to dmac2 for the scif1 node in r8a7795.dtsi, does debug serial 1 still work? +10:50 < khiemnguyen> geertu: OK. Let me try it and inform you the result. +10:50 < shimoda> sorry for the late. as khiem-san mentioned, the firmware 2.8.0 has update for SYS-DMAC2. and bsp team confirmed the dmac work correctly. +10:50 < geertu> khiemnguyen: thx +10:51 < geertu> shimoda: Great! +10:51 < geertu> So we can start adding dmas pointing to dmac2 where appropriate +10:52 < geertu> I'll add a task for that +10:52 < dammsan> geertu: no update from my side +10:53 < geertu> dammsan: Do you plan to have more discussions (and I will s/v4.6/v4.7/), or are we finished discussing SMP DT bindings (and I will mark it completed)? +10:54 < dammsan> good question +10:54 < shimoda> by the way, v2.8.0 also enables data conversion feature though :) as we discussed before, for short term, we should disable the feature +10:54 < morimoto> (unfortunately, I will go to next meeting) +10:55 < dammsan> i think keeping it for a while is good +10:55 < geertu> morimoto: thanks, and have a nice continued day! +10:57 < geertu> W.r.t. SYS-DMAC2, the wiki doesn't have boot loader v280 yet (latest is v270) +10:58 < geertu> Which brings us to another interesting question. +10:58 < geertu> When do we update the DTS with features that depend on firmware versions? +11:00 < horms> I gather the issue here is about backwards copmatibility. I.e. new DT with old FW. +11:01 < geertu> Yes +11:01 < geertu> Which is also relvant for "compatible = "arm,psci-1.0"; +11:01 < geertu> s/relvant/relevant/ +11:01 < geertu> whicb BTW, can be detected at run-time... +11:02 < horms> ok, if it can be detected at run time then perhaps it should be :) +11:02 < dammsan> run-time detection must be best if possible +11:02 < geertu> Yeah, DT describes the hardware bla bla bla +11:02 < horms> but I guess in the general case we may have to document minumum FW revisions +11:03 < geertu> Yes, add a comment at the top of r8a7795.dtsi? +11:03 < horms> That might be a good start. +11:05 < khiemnguyen> geertu: horms: psci-1.0 can be detected at runtime. I have replied the thread. +11:05 < horms> excellent, thanks +11:07 < geertu> OK, let's move on +11:07 < geertu> DMAEngine,v4.7,prototype,?,Implement proper solution with IPMMU +11:08 < geertu> Should the "?" be "magnus"? +11:08 < geertu> Update to v4.8? +11:09 < neg> how is this task different from 'Discuss API changes on the dma-engine mailing list' ? +11:09 < geertu> discuss vs. implement? +11:11 < neg> hum OK, the patches I try to get Hellwigs attentinon on have one implementation for this, if it is proper or not I do not know :-) +11:12 < geertu> OK, I'll keep the "?" for now +11:12 < horms> I wonder how we can get Christoph's attention +11:12 < geertu> Beer? +11:12 < horms> Probably +11:13 < horms> If I see him I will give him some. But perhaps that shouldn't be our plan A :) +11:13 < geertu> Will he be at LCJ? The LCJ schedule hasn't been announced yet +11:13 < neg> My plan is to resend the patch later this week, I got feedback from Robin Murphy so I need to fix onething in it +11:15 * pinchartl is back +11:15 < geertu> Ok. It's still the merge window, so people may be busy with that +11:15 < geertu> pinchartl: Welcome! +11:16 < geertu> Back to the mode pins... +11:16 < geertu> So Dirk Behme is more or less pushing us to pick a solution +11:16 < pinchartl> (quick comment about sharing DT sources between H3 and M3: maybe we shouldn't have per-soc compat strings ;-)) +11:16 < horms> pinchartl: i knew you would say that :^) +11:17 < geertu> pinchartl: We can add them dynamically with an early DT fixup? +11:17 < geertu> Oh well... +11:18 < geertu> Back to the mode pins... +11:18 < pinchartl> yes +11:18 < pinchartl> so what's the status there ? +11:18 < geertu> Dirk has posted updated versions of both Simon's and my proposals +11:19 < geertu> I.e. rebased and extended to r8a7796 +11:19 < pinchartl> nice +11:19 < pinchartl> do they both work ? +11:19 < horms> FWIW I felt that geert's approach was cleaner. +11:19 < geertu> He claims they do, and I don't see a reason why not. +11:20 < pinchartl> horms: that's using syscon, right ? +11:21 < horms> yes +11:23 < pinchartl> I still don't like it. not such much because of the C implementation, but because referencing modemr in DT isn't a hardware description +11:25 < pinchartl> feel free to voice your disagreement with that opinion :-) +11:25 < geertu> The CPG hardware must have a link to the mode pins though +11:27 < pinchartl> yes +11:27 < pinchartl> that's for sure +11:27 < pinchartl> both the CPG and RST chapters of the datasheet list the MD pins in their external pins section +11:28 < geertu> But the RST is responsible for latching them ("Latching of the levels on mode pins when PRESET# is negated") +11:31 < pinchartl> yes, but that's not related to the modemr register per-se +11:32 < pinchartl> if the values of the MD pins were scattered across several registers +11:32 < pinchartl> or made accessible in an even more complex way to software +11:32 < pinchartl> would you still put the access logic in each driver that needs to know the value of the modemr pins ? +11:33 < pinchartl> that's what bothers me, boot mode configuration should be a system service, not something that is hacked by each driver +11:33 < pinchartl> of course in this case accessing the register is simple +11:33 < geertu> No, we'd provide an API. +11:33 < horms> So the way that I see things is this: On the one hand pushing things out to DT seems to lead to a cleaner implementation in software. But on the other hand it might be cleaner from a design point of view not to have this information in DT at all. +11:33 < pinchartl> but what if you needed to enable clocks to access that register ? +11:33 < pinchartl> or power domains ? +11:34 < pinchartl> we could argue that accessing the information is simple and that we don't need an API now +11:34 < pinchartl> we could implement an API later +11:34 < pinchartl> but we'd be stuck with the syscon method for all existing socs +11:34 < geertu> Let's stick the API in include/linux/soc/renesas/rcar-rst.h for now? +11:35 < pinchartl> horms: yes, for our current use cases, it's easier to use rst,modemr than designing a new API +11:35 < geertu> And the driver in drivers/soc/renesas/rcar-rst.c? +11:35 < pinchartl> geertu: I'd be fine with that +11:35 < pinchartl> that can be changed later if needed without any DT ABi breakage +11:36 < geertu> A generic API for all SoCs and architectures can still be done on top of that later +11:37 < pinchartl> if that's fine with everybody it's fine with me +11:38 < horms> I think I am fine with it +11:38 < geertu> Yep +11:38 < pinchartl> we would (at least temporarly) lose the ability to use the CPG on a non-Renesas platform, but I doubt that's a problem :-) +11:38 < geertu> I'll write it down in the meeting minutes, and we can let the idea cook for a few more days +11:39 < horms> good plan +11:39 < horms> pinchartl: i don't think that is a problem either :) +11:39 < geertu> OK, case closed...

New upstream DRM/KMS rules [18:04] +<pinchartl> this one is a rather bad one +<pinchartl> DRM/KMS has long required GPU kernel drivers to have an + open-source userspace implementation in order to get merged +<pinchartl> that's at least how the rule was communicated interpreted [18:05] +<pinchartl> they're now changing, if not their base rule, at least how they + apply it +<pinchartl> and require open-source userspace upstream code for any new kernel + API +<pinchartl> including driver-specific properties +<pinchartl> z-order and alpha support got accepted right before they decided + to enforce that rule [18:06] +*** horms (~horms@reginn.isobedori.kobe.vergenet.net) has quit: Quit: Leaving +<pinchartl> but from now on, an implementation in Android hardware composer, + wayland or X11 will be required for any API extension +<pinchartl> this is a major issue for us +<pinchartl> as our team works on the kernel side only [18:07] +<pinchartl> not only don't we have the bandwidth to cover the userspace side +<pinchartl> but userspace is the responsibility of other teams within Renesas, + and we can't claim ownership of those areas +<pinchartl> the new rule will be announced shortly [18:08] +<pinchartl> there will likely be a grace period +<pinchartl> but we'll have to adjust +<pinchartl> I've learnt about that yesterday and don't have a plan yet +<pinchartl> any comment ? +<uli___> so does the userspace part only have to exist somewhere, or does it + really have to be upstream? [18:09] +<pinchartl> it has to be acked by upstream developers +<pinchartl> not merged obviously, as it can't be merged before the kernel API + is available [18:10] +<morimoto> does z-order and alpha support will be updated ? +<pinchartl> they will be merged in v4.8 as they have been accepted right + before the change of rule [18:11] +<pinchartl> but if they hadn't been +<pinchartl> we would have had to submit patches to android hwcomposer, weston + or X11 to use Z-order and alpha +<pinchartl> so this might mean we'll have to collaborate with the Renesas + upstream developers [18:14] +<pinchartl> s/upstream/userspace/ +<pinchartl> I'll bring that topic up during the meeting in Japan +<pinchartl> any suggestion regarding what to do in the meantime will be + welcome [18:15] +<pinchartl> while this sinks in +<pinchartl> Topic 4. Renesas requests +<pinchartl> Morimoto-san, you've updated multimedia/request [18:16] +<pinchartl> how are we supposed to handle that list ? +<pinchartl> is it just there to keep track of the request, and let us propose + additional tasks (or handle them as part of the base contract), or + do we need to be more proactive ? [18:17] +<morimoto> It is not a big deal, just for my / Renesas information +<morimoto> I sometimes requests something, and clean forgot :) [18:18] +<pinchartl> ok, so no action required from me, apart from looking at it and + using it as a source of inspiration to propose tasks ? +<morimoto> I would like to track what is requested, and current status +<morimoto> something like that [18:19] +<pinchartl> thanks [18:20] +<pinchartl> Topic 5. VSP unit tests +<pinchartl> as I mentioned earlier, we now have a vsp unit tests framework +<pinchartl> it's implemented as a set of shell scripts using the yavta and + media-ctl test tools +<pinchartl> as well as the compare utility from ImageMagick [18:21] +<pinchartl> on the host side python is also needed to generate test data +<pinchartl> there are 8 tests so far, and they already allowed me to catch two + bugs in the vsp driver, for which I've submitted patches +<pinchartl> I plan to add more test script in the future +<pinchartl> and will also need to work on creating a new test tool to generate + test data (both input reference frames and excepted output frames + for comparison) at runtime instead of build time [18:22] +<pinchartl> as there's already 230MB of test frames, and that won't scale +<pinchartl> new test scripts will be added as I develop driver features +<pinchartl> and I'll propose an additional task for work on the test framework + core, as that will need quite a bit of time [18:23] +<pinchartl> I encourage you all to start thinking about unit test scripts for + the driver(s) you work on +<kbingham> pinchartl: I'd been looking at gstreamer as a potential for testing + my M2M driver - as the Videotestsrc element will enable me to + create many types of frames consistently - dynamically. +<pinchartl> feel free to use vsp-tests as a base and provide feedback +<pinchartl> for the FDP I think that's an option [18:24] +<pinchartl> it would depend on gstreamer obviously, but that shouldn't be a + too big deal +<pinchartl> on the other hand [18:25] +<pinchartl> gstreamer will only exercise the API as it's meant to be used +<pinchartl> if you want to unit-test the error paths then you'll need + something at a lower level +<kbingham> yes. that's true. +<pinchartl> but you can have diffrent unit test scripts that use different + tools [18:26] +<pinchartl> I'm fine with gstreamer, but if you realize that you could perform + the exact same tests easily with less dependencies, then I'd + prefer avoiding gstreamer +<pinchartl> if it brings added value, then no worries +<kbingham> Ok - I'll bear that in mind :) [18:27] +<pinchartl> regarding the test scripts themselves, we should standardize on + naming, output and other technical details to make sure they could + all be run from a single test runner, and generate a coherent + report +<pinchartl> I haven't given that much thoughts yet on my side +<pinchartl> if you start writing unit test scripts please get in touch with me + to discuss those points [18:28] +<pinchartl> that's all I have on this topic [18:29] +<pinchartl> Topic 5. Next meeting +<pinchartl> I propose Wednesday in two weeks (8th of June), same time as today +<kbingham> Ok for me. [18:30] +<uli___> me too +<neg> OK for me +<morimoto> OK for me too +<pinchartl> dammsan: ? +<morimoto> (Mr Magnus is still taling to Renesas guy) +<pinchartl> ok :-) +<pinchartl> I assume he will voice his concerns over e-mail if there's any + issue +<pinchartl> we're done with the agenda, any last remark or question ? [18:31] +<morimoto> pinchartl: thank you for your new topic for RenesasCon +<pinchartl> you're welcome +<pinchartl> it's two new topics actually [18:32] +<pinchartl> I plan to talk about the test framework too +<pinchartl> in addition to the DRM/KMS rule change +<pinchartl> but regarding the test framework +<pinchartl> we should discuss it internally first before adding the topic to + the RenesasCon agenda +<pinchartl> we can talk about it during the next multimedia meeting, I will + hopefully have a bit more information by then [18:33] +<pinchartl> and others will hopefully have time to give it a look too :-) +<pinchartl> I propose adjourning for today. does everybody second ? [18:34] +<kbingham> Seconded :) +<pinchartl> thank you for joining everybody [18:35] +<pinchartl> have a nice day +<uli___> cu +<neg> thanks all [18:36] +<kbingham> Thanks :) +<morimoto> pinchartl: it seems we need Kurokawa-san to next meeting ? +<morimoto> for DRM/KMS topis [18:37] +<morimoto> topis/topics +<pinchartl> morimoto: that could be useful +<morimoto> OK +<morimoto> thanks +<pinchartl> I'd like to think about it for a couple of days and then discuss + it with you and Magnus +<morimoto> OK. by chat ? [18:38] +<pinchartl> or e-mail [18:40] +<pinchartl> both are fine with me +<pinchartl> I'll likely chat with Magnus about this when he won't be busy with + "the Renesas guy" :-) [18:41] +<morimoto> OK :) +<morimoto> I can ask it to him, after kicking Renesas guy :) [18:42] +<morimoto> kbingham: can I ask you ? +<morimoto> kbingham: are you still there ? +<kbingham> morimoto: I'm here :) +<morimoto> thanks. does your question about FDP parent clock [18:43] +<kbingham> morimoto: How can I help ? +<morimoto> does it just parent clock for CPG ? +<morimoto> or do you have some issue on it ? [18:44] +<kbingham> morimoto: Thats correct. +<morimoto> OK, so you have no big issue now +<kbingham> morimoto: I don't think there is an issue currently. I can read and + write to the registers - so I assume we have it right, but I don't + have a datasheet clock diagram to confirm it is correct (and not + that I'm just lucky and something else has actually turned the + clock on for me) +<pinchartl> morimoto: it's the usual "what is the correct parent for the MSTP + clock" question. the FDP doesn't care about the clock rate so it's + no big deal, it's just about correctness [18:45] +<pinchartl> (I'll be back in 20 minutes) +<morimoto> Yeah, same here. +<morimoto> According to HW / datasheet guys, they decided to indicate it in + block diagram [18:46] +<morimoto> but, not yet completed +<morimoto> OK, thanks. I asked it to HW / datasheet guys. please wait [18:47] +<kbingham> morimoto: Ok - so just waiting on them finishing the document. +<morimoto> Thanks +<kbingham> morimoto: Thankyou :) diff --git a/wiki/Chat_log/20160608-mm-chatlog b/wiki/Chat_log/20160608-mm-chatlog new file mode 100644 index 0000000..4371ce8 --- /dev/null +++ b/wiki/Chat_log/20160608-mm-chatlog @@ -0,0 +1,441 @@ +Multimedia-chat-meeting-2016-06-08 + +<neg> hi all [16:52] +<morimoto> hi [16:53] +<uli___> hello +*** dammsan (~dammsan@s214090.ppp.asahi-net.or.jp) has joined channel + #periperi [16:55] +<morimoto> hi mag-mag +<dammsan> hi mori-mori +<kbingham> Morning' +<morimoto> Hi kbingham [16:56] +<dammsan> hi! +<kbingham> I guess it's 'good afternoon' for morimoto + dammsan :) [17:01] +<morimoto> Yes :) [17:02] +<pinchartl> sorry, I'm late +<pinchartl> hello everybody +<morimoto> hi +<kbingham> Hola!

That clears that up for me :) +<pinchartl> so, additional tasks for May [18:08] +<pinchartl> has everybody sent their report ? +<neg> yes, report is sent and test procedure on elinux.org +<pinchartl> great [18:09] +<uli___> report and invoice sent :) also, instructions on elinux.org +<pinchartl> where on elinux.org by the way ? +<neg> http://elinux.org/R-Car/Tests:rcar-vin [18:10] +<uli___> http://elinux.org/User:Uli/Tests:KMS [18:11] +<dammsan> uli___: about resending the HDMI prototype, can you please try to do + it before the end of this month? +<dammsan> i'm asking because we want to check the result [18:12] +<uli___> i'll try to squeeze it in then +<dammsan> and timing wise if it happens next month it is too late to decide + next quarter additional task +<dammsan> thanks, please do!! +<pinchartl> uli___: could you move http://elinux.org/User:Uli/Tests:KMS to + http://elinux.org/R-Car/Tests:KMS ? [18:13] +<pinchartl> and add a link to http://elinux.org/R-Car/Devices ? +<dammsan> pinchartl: please keep the URLs half-stable, I've forwarded these to + people inside renesas for checking +<morimoto> dammsan: uli___: I believe it is for "HDMI-OUT for ES1.1" ? +<pinchartl> dammsan: we can add a redirection +<dammsan> pinchartl: sounds good, thanks! [18:14] +<pinchartl> neg: could you add a link to the VIN tests to + http://elinux.org/R-Car/Devices ? +<uli___> will do +<neg> pinchartl: sure +<pinchartl> thank you +<pinchartl> you can add sections for VIN and DU in + http://elinux.org/User:Uli/Tests:KMS [18:15] +<pinchartl> oops, I mean in http://elinux.org/R-Car/Devices +<pinchartl> no need for a long device description for now +<dammsan> uli__: can you please include the ES1.1 support in your HDMI out + prototype update? +<pinchartl> just create Tests section that link to the test pages +<neg> for future reference should we use 'R-Car/Tests:foo' ? There are also + for example 'Tests:SCIF-FIFO' +<uli___> dammsan: yes, that's the one thing [18:16] +<dammsan> great, thank you! +<pinchartl> neg: that sounds good to me +<pinchartl> now, about additional tasks for June [18:17] +<pinchartl> are we on track ? +<pinchartl> any issue ? +<uli___> i'm ok so far [18:18] +<neg> I'm a bit scared of doing both HDMI and i2c secondary device in one go + for ADV7482 but have not yet started so maybe the i2c part is easy :-) + Will let you know if I run into trouble [18:19] +<pinchartl> ok. please let me know as early as possible +<neg> will do, thanks [18:20] +<pinchartl> the I2C part should be easy +<pinchartl> Topic 3. Additional tasks for next quarter [18:21] +<neg> good, then I feel I'm on track +<pinchartl> dammsan: do you want to drive this ? +<dammsan> thanks +<dammsan> i'd like to specify tasks in two batches +<dammsan> one i'd like decide in the middle of this month +<dammsan> the next around meeting time in July +<dammsan> the deadlines for the two batches are supposed to be 8/M and 9/M + [18:22] +<dammsan> we may be able to do remote access for M3-W for the 8/M tasks +<dammsan> but real physical hardware access will not be possible for 8/M + target [18:23] +<dammsan> so instead of focusing on the entire quarter i'd like to begin with + focusing on the 8/M target that we should decide this month +<pinchartl> will it be possible for 9/M ? +<dammsan> maybe +<dammsan> kind of unlikely to be honest +<dammsan> we will know more during the meeting in japan [18:24] +<dammsan> as for what kind of tasks to deal with +<dammsan> i'd like to get a bunch of proposals +<pinchartl> ok +<dammsan> both from you guys +<dammsan> and also ask internal renesas if they have something for us [18:25] +<dammsan> we will meet f2f with multimedia people next week +<dammsan> hopefully that will result in an updated list +<pinchartl> ok +<pinchartl> should we start now, or would you like to get them by e-mail ? + [18:26] +<dammsan> i'l like you to start the process in your head +<dammsan> but after that email would be good =) +<dammsan> also agreeing on a schedule for fixing tasks would be good [18:27] +<dammsan> when do you intend to hold next chat meeting? +<pinchartl> in two weeks +<pinchartl> 22nd of June +<dammsan> thanks [18:28] +<pinchartl> is that fine for everybody by the way ? +<pinchartl> same time as today +<dammsan> so can we have title proposals done by the 17th? +<pinchartl> (morimoto: thanks for your e-mail with the status update, I've + incorporated it) +<dammsan> for some overview +<neg> pinchartl: time and date works for me [18:29] +<morimoto> pinchartl: thanks +<dammsan> pinchartl: scrap the 17th +<dammsan> pinchartl: i think we should provide you a list of requests from + renesas on the 17th +<dammsan> can we have the titles done by the 22nd then? [18:30] +<pinchartl> that's fine with me +<dammsan> thanks +<dammsan> so the time around 20th and later is needed to fix some tasks + [18:31] +<neg> Hum are there any information about schematics for M3-W? To look for + tasks it would help me to be able to look at how VIN is setup +<pinchartl> neg: uli___: kbingham: could you start thinking about tasks + proposals for Q3 in parallel ? I'd like to hear your ideas on what + is needed for multimedia support in the areas you're responsible + for (and possibly other areas as well) [18:32] +<pinchartl> dammsan: as we've discussed previously, video codecs, video test + framework (extension of the VSP test framework to cover other + devices and more features) and suspend/resume support for the VSP + driver are possible candidates for Q3 [18:33] +<kbingham> pinchartl: Ack. I'll have an explore around to see what's what :) + [18:34] +<pinchartl> kbingham: thanks +<morimoto> neg: basically H3 Salvator <-> M3 Salvator are same board. I can + say "Basically" :) +<morimoto> pinchartl: now I got VSP1 bug-report from BSP team. I will report + it to you tomorrow [18:36] +<pinchartl> morimoto: thank you. how many dozens of pages are there ? :-) + [18:37] +<neg> morimoto: ok thanks, so its the same utilisation of CSI-2 and no digital + video source for VIN? +<morimoto> neg: if it was so in H3, basically yes [18:38] +<morimoto> pinchartl: let me check +<pinchartl> we've covered all the topics for today. any last comment/question + from anyone ? +<dammsan> nope, thanks for your help! +<neg> I'm happy, thanks all [18:39] +<morimoto> pinchartl: it seems that BSP team already found issue +<morimoto> only 100 dozens [18:40] +<pinchartl> :-) +<pinchartl> I'll try not to have nightmares about them tonight +<pinchartl> thank you for attending everybody +<pinchartl> have a nice evening or day +<morimoto> Thanks, bye +<pinchartl> (report sent) +<morimoto> have a nice nightmares :) [18:41] +<dammsan> thanks guys +<kbingham> Cheers! +<uli___> cu [18:42] diff --git a/wiki/Chat_log/20160609-io-chatlog b/wiki/Chat_log/20160609-io-chatlog new file mode 100644 index 0000000..fdfc144 --- /dev/null +++ b/wiki/Chat_log/20160609-io-chatlog @@ -0,0 +1,286 @@ +--- Log opened Thu Jun 09 09:58:45 2016 +09:58 -!- wsa_ [~wsa@dslb-178-012-237-128.178.012.pools.vodafone-ip.de] has joined #periperi-io +09:58 -!- Irssi: #periperi-io: Total of 2 nicks [1 ops, 0 halfops, 0 voices, 1 normal] +09:58 -!- Irssi: Join to #periperi-io was synced in 3 secs +10:00 -!- morimoto [~user@relprex3.renesas.com] has joined #periperi-io +10:00 -!- geertu [~geert@d54C36B15.access.telenet.be] has joined #periperi-io +10:00 < geertu> G'day +10:00 <@uli___> good morning +10:01 < morimoto> hi +10:01 -!- shimoda [~shimoda@relprex2.renesas.com] has joined #periperi-io +10:01 < shimoda> hi +10:01 < wsa_> hi all +10:02 -!- Irssi: #periperi-io: Total of 5 nicks [1 ops, 0 halfops, 0 voices, 4 normal] +10:03 < wsa_> geertu: short question before: I assume I don't need to send a pull-request for the H3-PFC-voltage-switching topic branch?

+10:16 < shimoda> i tried to debug EHCI + IPMMU on Gen3, but it doesn't work yet +10:17 < wsa_> pity +10:17 < shimoda> also I will do OTG support because some related framework is coming soon and TI guys requests me about it +10:17 < shimoda> usb3 suspend issue, i don't have any update +10:18 < shimoda> that's from my side +10:19 < horms> shimoda: are you planning to resubmit DTS patches for gen3 usb? +10:19 < wsa_> geert recently mentioned that CMA cannot be enabled because of USB +10:19 < wsa_> is this a known issue for you? +10:19 < shimoda> i will resubmit it after phy maintainer applied a bugfix patch +10:20 < wsa_> "OHCI-PCI doesn't seem to work with CONFIG_DMA_CMA=y (ohci-pci 0001:01:01.0: OHCI Unrecoverable Error, scheduling NEC chip restart)" +10:21 < wsa_> i guess we should make a task out of it +10:22 < shimoda> horms: if possible, i would like to resubmit without hsusb enable patch. is it acceptable? +10:23 < horms> Ok, so basically patches 1 - 3, but not patch 4 ? +10:23 < horms> I am referring to: [PATCH v2 0/4] arm64: dts: r8a7795: Add HSUSB device node and enable channel 0 of USB2.0 +10:23 < shimoda> horms: yes, but i should test such a case though :) +10:24 < wsa_> the question would be then if you have time for it or if it is okay if someone else has a look? +10:26 < shimoda> wsa_: about CMA issue in gen2, i don't have any information... but I guess this is related to memory range or somethings +10:26 < shimoda> the hardware cannot access 4GB over area +10:26 < horms> shimoda: I think I am ok with that approach +10:27 < wsa_> neg: how's your bandwidth currently? :) +10:28 < shimoda> horms: thanks! after I tested it, i will submit it. maybe tomorrow +10:28 < horms> thanks. no rush from my side :) +10:28 < neg> wsa_: a bit swamped for this month, next month nothing planed yet +10:28 < shimoda> horms: i got it :) +10:28 < wsa_> ok +10:28 < wsa_> looks like this task has to wait for July then +10:29 < wsa_> let's see about capacities then +10:30 < wsa_> ok, simon, your turn now +10:30 < horms> sure +10:31 < horms> I have made some progress on i2c demux +10:31 < horms> so far I have only focused on lager as I'd like to get the requirements sorted before extending to other boards +10:31 < horms> I think that may be close but as per my v2 positing my testing indicates that not all combinations work as i might have expected +10:32 < horms> That angle I'm not so sure how to move forwards on. I was kind of hoping wsa_ might look into it. +10:32 < geertu> horms: Are there bugs in the pfc-r8a7790 driver? +10:32 < horms> I have considered that +10:32 < horms> And I spent quite some time comparing pfc-r8a7790.c to the documentation I have +10:33 < horms> in particular the i2c related portions of both +10:33 < horms> but I have been unable to find anything that looks wrong +10:34 < wsa_> I have to admint I missed the "Discussion of Testing" part of your cover letter :( +10:34 < wsa_> however I managed to do that +10:34 < wsa_> will have a look later +10:35 < horms> No problem. It seems that I now have your attention :) +10:35 < horms> Thanks +10:35 < horms> Moving on +10:35 < wsa_> GPIO fallback worked for me on I2C2 +10:35 < geertu> BTW, have you seen Pantelis' DT connector work? +10:35 < horms> Ok. It didn't seem to work for me. Lets try to work out what the difference is. +10:35 < geertu> It's somewhat related +10:35 < horms> No, I have not seen that +10:36 < horms> --- +10:36 < geertu> The connector work abstracts the functionality that can be provided on a set of pins +10:37 < geertu> E.g. 2 pins can be used as 2 GPIOs, a UART, or an i2c bus. +10:37 < geertu> basically DT pinctrl on steroids +10:38 < horms> ok +10:38 < horms> it does sound somehow related +10:38 < geertu> We want to use a set of pins for a fixed functionality, but change the "driver" behind it +10:39 < geertu> It's too early to see how it can be integrated, though, but I wanted you to be aware of it. +10:39 < geertu> Pantelis also gave a presentation about it at ELC2016 +10:39 < geertu> perhaps Niklas saw it? +10:40 < neg> hum not that I can recall right now +10:40 < geertu> He wants to describe a connector (expansion port) in term of the functionality it can provide, so the user doesn't have to care about the deep details. +10:40 < geertu> Mostly focussed on BeagleBone series. +10:41 < geertu> That's it +10:41 < horms> Ok, thanks for the info. +10:41 < horms> My other task is Gen 3 SDHI DMA +10:42 < horms> The task is to upstream the Gen 3 SDHI DMA driver, which is different from the non-Gen3 SDHI DMA driver. +10:42 < horms> And in possible preparation for even more DMA drivers, e.g. for different Gen3 SoCs. +10:42 < horms> The approach I am taking so far is as follows. +10:42 < horms> 1. Rename sh_mobile_sdhi.c as renesas_sdhi.c (not strictly related) +10:43 < horms> 2. Refactor the TMIO DMA code so that it is provided by a set of callbacks rather than compiled-in function calls; Refactor the DMA SDHI to use this. +10:44 < horms> 3. Rename tmio_mmc_dma.c as renesas_sdhi_dma.c which reflects more closely what it is is, particularly after step 2. This is why I wanted the rename in step 2: to avoid adding another sh_mobile file when I am separately trying to convert to "renesas" +10:45 < horms> 4. Add Gen3 DMA code as a separate set of callbacks +10:45 < horms> The SDHI code itself knows which callbacks to instantiate based on the compat-string: its in the probe function +10:45 < horms> The two sets of DMA callbacks may be compiled in at the same time. Though there are some caveats: +10:46 < horms> The Gen3 SDHI code doesn't seem to compile on ARM32 so I don't allow that +10:46 < horms> s/SDHI/SDHI DMA/ +10:46 < horms> I protected the non-Gen3 SDHI code with COMPILE_TEST on ARM64 as it will never actually be used +10:47 < horms> -- end summary -- +10:47 < horms> Oh sorry, one more thing. +10:47 < wsa_> caveats sound OK to me +10:47 < horms> The DMA code moves from the tmio_core to renesas_sdhi kernel module +10:47 < horms> the DMA code is not a separate module either before or after my proposed changes +10:48 < wsa_> general approach sounds good, too +10:48 < wsa_> how many callbacks are needed? +10:48 < horms> The result seems fairly clean within the context of the spagetti arrangement that tmio/sdhi is +10:48 < wsa_> :D +10:48 < horms> I don't recall exactly, but around 1/2 a dozen +10:48 < horms> I made a little structure for them +10:48 < wsa_> good +10:49 < shimoda> about gen3 sdhi, i'm not sure the final decition but I heard later gen3 socs have SYS-DMAC interface +10:49 < horms> ok. so the current arrangement allows us some flexibility on a per-soc basis +10:49 < horms> based on the compat string +10:49 < wsa_> yes, this was a priority for this task +10:49 < shimoda> horms: oh, i see. it's nice! +10:49 < horms> but the implication is that if the DMA code differs then the compat string should also differ. i.e. no generic gen3 fallback +10:50 < horms> possibly I should only enable your Gen3 DMA code for the H3? +10:50 < geertu> Goodbye renesas,rcar-gen3-*? +10:50 < shimoda> I have information about H3 restriction. please don't use multiple sdhi DMAC channels :) +10:51 < horms> ok +10:51 < horms> geertu: that is the implication. but perhaps its not a good choice +10:51 < shimoda> after that, sometimes read data is lost +10:51 < horms> ok, so how might I enable multiple channels? +10:51 < horms> (or not!) +10:51 < shimoda> s/is lost/is delayed/ +10:52 < geertu> shimoda: probably this is about concurrent use? +10:52 < horms> geertu: would it be better to have a property of the sdhi node that indicates a flavour of dma to be used on gen3? +10:53 < shimoda> geertu: yes. if we use multime channels at the same time, read data is delayed. so, if driver do unmap soon, the data is lost +10:54 < wsa_> ouch +10:54 < shimoda> this restriction will be fixed in next ES. This issue has H3 ES1.1 and M3-W +10:54 < shimoda> Oops, H3 ES1.1 and M3-W have this issue +10:57 < horms> Ok. Perhaps we can move on. We can come back to this. e.g. when I've posted some patches +10:58 < wsa_> that hurts. given that SDHI also does eMMC on Gen3, only one DMA channel will affect either rootfs or SD card reading :/ +10:58 < wsa_> ok +10:58 < wsa_> geertu, how are things? ;) +10:59 < geertu> SCIF,v4.7,public,geert,Extend subsystem with GPIO-based software handling and hardware flow control +10:59 < geertu> v3 posted, no changes except for acks etc +10:59 < geertu> SCIF,?,noplan,?,Add support for hardware assisted modem-control +10:59 < geertu> included in v3 above (was also included in v2) +11:00 < geertu> SCIF,v4.8,plan,geert,SCIF FIFO flushing +11:00 < geertu> posted, test on elinux wiki +11:00 < geertu> (invoice/report May 31) +11:01 < geertu> SPI,2016-05-31,plan,geert,Implement initial SPI slave prototype support for R-Car Gen2 +11:01 < geertu> I'm doing this as a little side job, where time permits +11:02 < wsa_> great +11:02 < geertu> I've verified that the code from the BSP works, and allows to receive/transmit known-size messages, triggered by the SPI master +11:02 < wsa_> i hope it will be one of your additional tasks next quarter +11:02 < geertu> I've fixed the obvious hacks in the code (like redefining HZ :-) +11:03 < geertu> I'm thinking about DT / core changes needed to handle it properly +11:03 < geertu> I hope to post some minimal prototype / RFC around the deadline for ELCE submissions +11:04 < wsa_> wanna talk about it?

Control of CPG parent clocks +10:09 < horms> sorry, i was slow +10:09 < horms> about r8a7792 +10:09 < geertu> yes +10:09 < horms> it seems his patchset is getting very close +10:09 < horms> and SMP even works +10:09 < horms> but we did get burnt with SMP on the r8a7795 +10:09 < horms> (my fingers are still in bandages) +10:09 < geertu> using the deprecated smp ops +10:09 < horms> do you have any opinion on the smp aspects of his patchset? +10:10 < geertu> r8a7792 SMP is different. It should be similar to other Gen2. While r8a7795 depends on PSCI +10:10 < geertu> We should not merge his SMP patch/ +10:10 < geertu> as we decided to no longer add new per-SoC platform code for that +10:11 < horms> Ah! +10:11 < geertu> cfr. r8a7793 still lacking SMP support +10:11 < horms> ok +10:11 < geertu> Magnus did post patches for using that a while ago, which I have been rebasing and keeping around locally. +10:11 < horms> have you brought this to Sergei's attention? +10:11 < geertu> I'll rework that and post them to the mailing list. +10:11 < horms> ok +10:11 < geertu> After that, r8a7792 support shouldn't need any platform code for SMP. +10:12 < horms> so if Sergei wants his patches to go in quickly he should drop SMP support +10:12 < geertu> The complication here is that doing it without any platform code needs a SYSC device node in DT. +10:12 < geertu> Which we have for r8a7792 (and r8a7793 now). +10:13 < geertu> Hence the major mess is that some SoCs have it, others don't. +10:13 < horms> Don't tell Dirk :^) +10:13 < geertu> I'll have to look into that again to untangle the mess and create a patch set that moves us forward. +10:13 < horms> Is the way forwards to define a reference platform, get that working, then spread the love out to other SoCs? +10:14 < geertu> Yes, that's what Magnus already did. +10:14 < horms> Ok, and you are planning to revisit this? +10:14 < geertu> Yes. +10:14 < horms> Ok, got it. +10:14 < geertu> I had it locally (incl. for r8a7791) running for a long time. +10:14 < horms> I won't merge r8a7792 SMP without it +10:15 < horms> which from my pov should mean r8a7792 UP gets merged first +10:15 < geertu> If only we could drop backwards compatibility with old DT ;-) +10:15 < pinchartl> geertu: I won't oppose to that :-) +10:15 < horms> but Sergei can decide how fast he wants to move +10:15 < horms> geertu: it can be discussed with the BSP team if it is sufficiently important +10:17 < geertu> OK, so Sergei can continue, if he drops SMP for now. +10:17 < horms> agreed +10:18 < geertu> Next topic? +10:18 < geertu> Topic 2. Control of CPG parent clocks +10:19 < geertu> 1. How to set initial value. by DT? by C code? +10:19 < geertu> 2. We want to have max frequency? +10:19 < geertu> 3. We want to save power/frequency if no user? +10:19 < geertu> 4. Schedule? +10:19 < geertu> 5. Use cases from BSP team? +10:19 < geertu> a. MSIOF hi speed (?) need hi frequency +10:19 < geertu> Currently we just read the current values from the divider config registers +10:19 < geertu> For SDHI we have control of the parent clock (on R-Car Gen2) +10:20 < geertu> That is handled purely in the SDHI driver. +10:21 < geertu> My worries there are (a) that this is similar code that will end up in every single driver, and (b) that these drivers may run on platforms where they shouldn't touch the parent clock (cfr. SDHI changing the main peripheral clock on R-Mobile A1) +10:22 < geertu> Apparently the use case is increases the frequency of the MSIOF parent clock for faster SPI +10:22 < geertu> Morimoto-san: Is that correct? +10:23 < morimoto> Yes, it is +10:23 < morimoto> (at this point) +10:24 < pinchartl> regarding the initial value +10:24 < geertu> A quick solution would be to add similar code to the msiof driver like we did for sdhi +10:24 < pinchartl> we should read the value set by the boot loader(s) from the config registers to initialize the parent +10:25 < pinchartl> then there's the assigned-* DT clock properties that we can use +10:25 < pinchartl> it's not an ideal solution as it's more configuration data than a hardware description +10:25 < geertu> pinchartl: AFAIK we do read the initial value from the registers +10:25 < pinchartl> but it seems to be the upstream way of doing it +10:25 < geertu> pinchartl: Indeed, I don't like assigned-* at all +10:25 < geertu> pinchartl: Plus, for MSIOF you don't want to force this value. +10:25 < pinchartl> of course if there's a single consumer of the clock, then it would make sense for the driver to select the parent instead +10:26 < geertu> pinchartl: There are multiple MSIOFs +10:26 < pinchartl> the difficult case would be multiple consumers without assigned-* +10:26 < geertu> pinchartl: Some SPI slaves may be high-speed, others low-speed +10:26 < pinchartl> in that case the consumers would need to collaborate if you don't want to use assigned-* +10:26 < geertu> pinchartl: So it has to change dynamically +10:28 < geertu> I think MSIOF is also more complicated than SDHI as MSIOF has its own divider inside the module. +10:28 < geertu> So now you have two parameters: parent clock freq and per-device divider +10:29 < geertu> To get the wanted clock frequency, you can change one or both. +10:29 < geertu> Plus some other device may change the parent frequency behind your back, so you have to adapt the per-device divider +10:29 < geertu> if at all possible (and not out-of-range) +10:30 < geertu> And what if the parent frequency is changed while a transfer is in progress? +10:32 < pinchartl> that shouldn't be allowed +10:32 < horms> Are we expecting changes to occur at probe time or any time the driver feels like it? +10:32 < pinchartl> when you sya that some other device can change the frequency behind your back, to you mean another MSIOF device, or a completely unrelated device ? +10:32 < pinchartl> horms: at runtime unfortunately +10:33 < geertu> pinchartl: another MSIOF device (MSIOF parent is shared between MSIOF instances on Gen3) +10:34 < geertu> On Gen3, MSIOF parent is R8A7795_CLK_MSO +10:34 < horms> is it reasonable to wait for transfers to complete and then change the frequency? +10:34 < geertu> On Gen2, it's the shared MP clock +10:34 < geertu> horms: Sure +10:34 < pinchartl> geertu: then you need the drivers to collaborate +10:34 < geertu> but how to know? +10:35 < geertu> and how does the clock subsystem know a transfer is in progress? +10:35 < pinchartl> it doesn't +10:36 < pinchartl> that's for the driver to figure it out +10:36 < geertu> Ugh. +10:36 < geertu> So on Gen3, the msiof driver needs to know it shares a parent clock with other msiof instances? +10:37 < horms> do the instances use the same driver? +10:37 < geertu> On Gen2, it needs to know the parent clock is fixed (already handled ;-) +10:37 < pinchartl> some code might be moved to the ccf core if it's generic enough +10:37 < pinchartl> but there will be driver-specific code +10:37 < geertu> horms: Yes, spi-sh-msiof (assumed they use it for SPI, not for I2S) +10:37 < pinchartl> for instance you could extend the ccf api to add the ability to lock a clock +10:38 < pinchartl> while locked the frequency couldn't be changed by other drivers +10:38 < pinchartl> you'd have to decide what to do at unlock time though, whether frequency changes attempted while the clock is locked should be applied then +10:38 < pinchartl> or possibly use an unlock notifier +10:38 < geertu> I guess on some R-Mobile the MSIOF parent clock is shared with all other devices, and not fixed? +10:38 < pinchartl> but I'm not sure it would be useful in the ccf core +10:39 < pinchartl> as the msiof driver would need specific code to allow instances to collaborate to choose the frequency +10:39 < pinchartl> so it could as well handle the locking there too +10:40 < geertu> In the exterme case, the other instance has to wait until the first one releases the lock? +10:40 -!- shimoda [~shimoda@relprex2.renesas.com] has joined #periperi +10:40 < shimoda> hi +10:40 < geertu> Well, this definitely needs more thought... +10:40 < morimoto> In R-Mobile generation, if my memory was correct, we setuped parent clock in boot time as fixed rate. +10:40 < geertu> BTW, what do we do with SDHI, w.r.t. collaboration? +10:41 < horms> geertu: that was my first thought; and my second one (1. wait for lock 2. more thought) +10:41 < geertu> IIRC there are multiple SDHI parent clocks, but some are shared between two SDHI devices? +10:41 < morimoto> It doesn't have runtime exchange case +10:41 < geertu> morimoto: it = SDHI? +10:41 < morimoto> it = parent clock +10:42 < pinchartl> geertu: I'm not sure we need more thought, at this point I believe we need a prototype +10:42 < horms> I think it makes sense to handle this in the driver if it can be handled there. Once the implementation is all sorted out it could migrate into the core, if that makes sense. +10:42 < geertu> OK +10:42 < morimoto> We didn't expect that runtime parent clock exchange +10:42 < horms> I agree we need a prototype +10:42 < geertu> Sounds like an additional tasks for Q3 ;-) +10:43 < horms> morimoto: you mean that runtime clock exchange isn't a requirement at this point? +10:43 < geertu> " 3. We want to save power/frequency if no user? +10:43 < geertu> " +10:43 < morimoto> In R-Mobile generation ? Yes, it is not requirement. +10:44 < pinchartl> geertu: agreed regarding additional task. it might be more of a I/O task though +10:44 < morimoto> And it is not requirement on Gen3 too :) BSP team want to change initial rate only +10:44 < geertu> OK, so it's like SDHI, where we limited fiddling with the parent to Gen2 +10:44 < geertu> pinchartl: core + I/O +10:44 -!- horms2 [~horms@g1-27-253-251-9.bmobile.ne.jp] has joined #periperi +10:45 < geertu> "want to" != requirement? +10:45 < geertu> (Da evil twin brother has arrived?) +10:45 < morimoto> geertu: ? what is different ? +10:45 < horms> I'm trying to relocate. My twin is on my mobile. +10:46 < geertu> morimoto: OK, IC +10:46 < horms> morimoto: 1. Is it sufficient to do probe-time clock changes? 2. Is there an objection to run-time clock changes (as well) ? +10:46 < geertu> If it's just the initial value, it can be handled by assigned-rates +10:46 -!- horms [~horms@reginn.isobedori.kobe.vergenet.net] has quit [Quit: Leaving] +10:47 < morimoto> horms: 1. I think probe-time clock changes is very enough for BSP. +10:47 < geertu> But assigned-rates that has to take into account the whole system, which is complicated when someone uses DT overlays ;-) +10:47 < morimoto> horms: 2. I have no objection for run-time clock changes, but it is over-kill in my feeling +10:49 < geertu> In an SPI driver, you don't know the wanted frequencies during probe time +10:49 < geertu> Only when the SPI core calls .setup() +10:49 < geertu> When does DT assigned-rates kicks in? +10:50 < geertu> I assume it would not affect the MSIOF driver itself at all? +10:51 < horms2> I thought I saw that sdhi uses assigned-rates at probe time, but I could be mistaken +10:52 < morimoto> BSP team issue is that current MSIOF parent clock (= setuped by firmware ?) is not enough for hi speed. it is enough if CPG setup timing setups parent clocks more hi frequencies. +10:53 < geertu> horms2: It's parsed only in drivers/clk/clk-conf.c +10:53 < morimoto> .setup() can divide on each channels +10:53 < geertu> morimoto: Yes, it runs at 12.5 MHz instead of 66 MHz. +10:53 < pinchartl> geertu: MSIOF might want to change the parent clock frequency for two reasons, either because it's too low for the requested SPI frequency, or to achieve a more accurate SPI frequency +10:53 < geertu> pinchartl: Indeed +10:53 < pinchartl> in both cases a locked parent clock rate due to another transfer in progress wouldn't need to be treated as a fatal issue +10:54 < geertu> pinchartl: Yep +10:54 < pinchartl> the transfer could be performed at a lower than requested speed or at a less accurate speed +10:54 < pinchartl> but it also means that two identical transfer requests for the same device could lead to different speeds +10:54 < pinchartl> depending on the other transfers in progress +10:54 < geertu> pinchartl: Indeed. But the second instance should be able to lock the parent, too. So we need a R/W lock +10:54 < pinchartl> I wonder if that could be an issue for drivers +10:55 < pinchartl> the resulting speed wouldn't be deterministic +10:55 < geertu> pinchartl: Not for drivers, but for devices that have strict frequency requirements. +10:55 < pinchartl> at least from SPI drivers point of view +10:55 < geertu> I can imagine some device require to be driven at a specific frequency? Currently there's only max-frequency, and you usually get that +10:55 < pinchartl> although there's no guarantee in the SPI API that the requested speed will be honoured exactly (or with a certain accuracy) +10:56 < geertu> pinchartl: true +10:56 < pinchartl> what we guarantee today (at least in practice if not in theory) is that the speed will be the same for all transfers requested with the same speed +10:56 < pinchartl> that might change in the future +10:57 < pinchartl> I just wanted to mention the issue, it might not be a problem in practice +10:57 < geertu> Even if we don't support dynamic speed change, MSIOF instances are instantiated sequentially. +10:58 < geertu> So the first one decides? +10:59 < pinchartl> that's an open question +10:59 < geertu> OK, let's continue... +10:59 < geertu> Topic 3. CPG DTS clean up ("clock-output-names", CPG/MSSR, ...) +11:00 < geertu> This is a topic from Magnus +11:00 < geertu> 1. Can we do something to clean up the 32-bit ARM SoCs? +11:00 < geertu> 2. Can we make new SoC support slightly cleaner? +11:00 < geertu> 3. Shall we jump directly to CPG-MSSR for new SoCs and clean up the rest of the R-Car Gen2 +11:00 < geertu> family? +11:00 < geertu> But as he's not here, perhaps we should skip it? +11:01 < geertu> Or postpone till the end, if time permits? +11:01 < horms2> Probably a good idea +11:01 < geertu> Topic 4. Gen3 firmware plan for special memory allocation control +11:01 < morimoto> geertu: 1 question about parent clock.

But the details are under discussion (with you :) +10:12 < horms> uli___: are you handling PFC for r8a7796 these days? +10:12 < uli___> yes +10:12 < geertu> I'm afraid it's gonna miss today's renesas-drivers +10:13 < uli___> i have to wait to get remote access to m3-w to try it, at least once :) +10:14 < horms> ok, what is the hold-up there? +10:14 < uli___> i only asked for it an hour ago :( +10:14 < horms> ok +10:15 < dammsan> actually 25 minutes ago according to my email +10:15 < geertu> r8a7796 SYSC has been pulled by Simon +10:15 < geertu> r8a7796 CPG/MSSR is still in clk limbo +10:16 < geertu> dammsan: Are you travelling close to light speed? ;-) +10:17 < dammsan> well, i usually track days and not minutes =) +10:19 < geertu> Any other Upcoming Gen3 development for the Core group? +10:20 -!- khiemnguyen [d2a0fca8@gateway/web/cgi-irc/kiwiirc.com/ip.210.160.252.168] has quit [Quit: http://www.kiwiirc.com/ - A hand crafted IRC client] +10:20 -!- khiemnguyen [d2a0fca8@gateway/web/cgi-irc/kiwiirc.com/ip.210.160.252.168] has joined #periperi +10:21 < dammsan> I wonder what happened with that timer issue simon was debugging with the JTAG +10:22 < dammsan> and if it is the same thing that Geert is chasing RCU with? +10:22 < horms> I reached a dead end with my investigation there +10:22 < geertu> Was that emev2/kzm9d? +10:22 < horms> At this point I still have the JTAG (2) but no board. +10:22 < horms> yes, it was +10:22 < geertu> neg: Do you have JTAG? +10:24 < neg> I have a cheep clone not sure how good it is +10:24 < geertu> sheep or cheap? +10:24 < neg> used it for Cortex-M3 work so not sure if it works for Renesas boards, but if there is work I will buy one that works +10:24 < dammsan> neg: i can bring one to you if you happen to be in sweden +10:25 < dammsan> or you may as well get a new one +10:25 < geertu> Paul had some more suggestions to try, but I haven't found time for that yet. +10:25 < dammsan> geertu: can it be related to shared-override cache handling? +10:25 < geertu> And for me the board is remote. And doesn't do earlycon. +10:25 < neg> dammsan: yes I'm in Stockholm until it's time to go to Tokyo +10:26 < dammsan> neg: i'll bring one then +10:26 < dammsan> i'm leaving here on thursday +10:26 < geertu> dammsan: There's no pl310 cache controller +10:26 < geertu> But you do remind me that I should try with more errata config options enabled. +10:27 < dammsan> only l1? +10:27 < geertu> I think so. There's no L2 in DT. +10:27 < dammsan> hm... +10:27 < dammsan> but it should only affect things if we have bus mastering drivers +10:28 < dammsan> which we dont i think +10:28 < dammsan> only PIO +10:28 < geertu> Yes +10:28 < neg> dammsan: sure name a time and place and I can come and pick it up +10:28 < dammsan> adding earlycon may be rather simple +10:28 < dammsan> neg: thanks will do +10:29 < geertu> Next topic? +10:29 < geertu> Topic 2. CPG DTS clean up ("clock-output-names", CPG/MSSR, ...) +10:29 < geertu> 1. Can we do something to clean up the 32-bit ARM SoCs? +10:29 < geertu> 2. Can we make new SoC support slightly cleaner? +10:29 < geertu> 3. Shall we jump directly to CPG-MSSR for new SoCs and clean up the rest of +10:29 < geertu> the R-Car Gen2 family? +10:30 < geertu> This was proposed by Magnus for last meeting, but we didn't cover it due to lack of time, and lack of Magnus +10:30 < dammsan> =) +10:31 < geertu> We can definitely move to CPG-MSSR. The conversion is not that difficult, and easy to verify using /sys/kernel/debug/clk/clk_summary +10:31 < geertu> It does depend on sorting out the MODEMR accesses. +10:31 < geertu> One of them (arch timer frequency) has been removed. +10:32 < dammsan> geertu: we can keep old CPG + MSTP drivers around too for DT compatibility, right? +10:32 < geertu> dammsan: Yes we can. +10:33 < geertu> It's just that the current scheme of calling into the CPG driver from arch/arm/mach-shmobile to pass the mode pin state doesn't fly when you have two possible drivers to call into. +10:33 < dammsan> yeah +10:33 < dammsan> i never liked that one +10:33 < dammsan> and i tried to encourage people to do something else +10:33 < geertu> Yeah, we should have called into platform code from the clk driver instead. +10:34 < geertu> The second user of the mode pins is MD21 checking for SMP bringup. +10:34 < dammsan> yeah +10:34 < geertu> Which we should be able to remove soon too, thanks to Sergei diving into BSP codde. +10:34 < dammsan> uhm... +10:34 < geertu> According to the datasheet, these bits can be written to regardless of debug mode, so there's no need to check M21 +10:35 < geertu> (in theory) +10:35 < dammsan> this kind of discussion would take some time i think +10:35 < dammsan> for the SMP bits +10:35 < dammsan> but i wish sergey the best of luck +10:35 < geertu> morimoto-san: Do you know why the BSP writes into the undocumented bits of CA7DBGRCR? +10:35 < dammsan> but regardless +10:36 < dammsan> we do need some mode pin handling, no? +10:36 < geertu> Sure. +10:36 < geertu> [PATCH/RFC v3 00/22] soc: renesas: Add R-Car RST driver for obtaining mode pin state +10:36 < dammsan> what's the latest state with that? +10:36 < geertu> http://www.spinics.net/lists/linux-renesas-soc/msg04289.html +10:36 < morimoto> geertu: I'm not sure. Do you want me to ask BSP team ? +10:36 < geertu> Got some acks from people (all renesas-soc related only) +10:37 < geertu> morimoto: Yes, BSP and hardware people. +10:37 < dammsan> does it cover the product register too? +10:37 < dammsan> or will that be a different driver? +10:38 < geertu> ESx.y is something different. Albeit related, as it involves modifying the passed device tree. +10:38 < horms> geertu: is the missing piece and Ack from Mark Rutland +10:38 < dammsan> geertu: sure, just wonderig if the ESx.y detection register is in the RST range +10:38 < dammsan> hopefully not +10:38 < geertu> horms: No, from the reset maintainer. Which probably doesn't feel much involved, as the driver doesn't implement reset functionality +10:39 < geertu> dammsan: No, PRR is a completely different register. +10:39 < dammsan> geertu: ok good +10:39 < horms> ok. should we try to get that ack +10:39 < horms> or do we need more discussion +10:39 < horms> this issue seems to have been going around for a while +10:39 < horms> I for one had a go at it +10:39 < horms> I think this is your second attempt +10:40 < geertu> To make backward compatibility easier, I want to modify the device tree and add RST, SYSC, and APMU nodes if they're missing. +10:40 < geertu> Which brings us to +10:40 < geertu> [PATCH/RFC 0/1] soc: renesas: Add DT fixup code for backwards compatibility +10:40 < geertu> https://lkml.org/lkml/2016/6/1/742 +10:40 < geertu> That one implements adding the RST node only, but it can be extended for ESx.y handling. +10:40 < dammsan> geertu: can't you merge those in -staging to begin with? +10:40 < geertu> Then the PRR is hidden there. +10:41 < dammsan> geertu: thanks, i understand +10:42 < geertu> dammsan: staging? Lately Greg refused adding a new driver to staging, as he was wondering about a plan to get it out of staging +10:42 < dammsan> geertu: then plan would be to get it out once the reset maintainer agrees +10:42 < dammsan> or something =) +10:42 < geertu> Yes. Unless someone disagrees. +10:42 < dammsan> so do we need to add more reset functionality ? +10:43 < geertu> I don't think so. +10:44 < dammsan> ok fine with me =) +10:44 < geertu> It's called "reset controller", but it seems to differ from what Linux expects. +10:44 < morimoto> geertu: can I confirm ? what is your question about CA7DBGRCR ? +10:44 < horms> I'd vote for trying to get it merged not in staging unless we see a difficulty in achieving that +10:45 < geertu> renesas-backports/bsp/v3.10.31-ltsi/rcar-gen2-1.9.7:arch/arm/mach-shmobile/:smp-r8a7790.c: writel_relaxed((val | 0x01f83330), p + CA7DBGRCR); +10:45 < geertu> renesas-backports/bsp/v3.10.31-ltsi/rcar-gen2-1.9.7:arch/arm/mach-shmobile/:smp-r8a7794.c: writel_relaxed((val | 0x01f83330), p + CA7DBGRCR); +10:45 < geertu> morimoto: The 0x3330 part writes to undocumented bits +10:47 < morimoto> geertu: OK thanks. will ask +10:47 < geertu> morimoto: Thank you +10:48 < geertu> OK, I will refresh the RST series and resend (for v4.9) +10:48 < geertu> For the DT fixup, there were some review comments. +10:48 < dammsan> geertu: does it make sense to change the "old" CPG driver to use the new RST driver? +10:48 < geertu> And it will need changes to modify the DT before SMP bringup. +10:49 < dammsan> or is it better to jump to CPG-MSSR directly? +10:49 < geertu> dammsan: If we want to support old DT, the old CPG driver has to stay alive. +10:49 < dammsan> yes +10:50 < dammsan> but adding more dependencies to the old code may be just pure pain +10:50 < geertu> dammsan: Either it has to absorb the code to read MODEMR itself, or call into the RST driver. +10:50 < dammsan> (regarding adding some plink to the reset controller) +10:50 < geertu> There won't be a plink. +10:50 < geertu> plink = phandle? +10:50 < dammsan> gotcha +10:50 < dammsan> yeah +10:51 < dammsan> i meant phandle +10:51 < geertu> It calls rcar_rst_read_mode_pins() +10:51 < geertu> which either uses the RST node in DT, or falls back to hardcoded MODEM for backward compatbility code. +10:51 < geertu> The latter can be dropped again once we do DT fixup. +10:52 < geertu> s/MODEM/MODEMR/ +10:52 < dammsan> makes sense. reducing cross-tree symbol dependencies is always nice if possible +10:53 < dammsan> in my old mode pin hack i tried to store the mode pin setting in DT +10:53 < dammsan> by modifying it duringggggggg runtime +10:53 < dammsan> but it is a bit unholy +10:53 < dammsan> at the same time bordering to your run time patching +10:53 < geertu> Ah, you just added a property with the value? +10:53 < dammsan> yep +10:54 < dammsan> no special symbols needed +10:54 < geertu> Did you add it to the FDT or the unflatted one? +10:54 < geertu> s/unflatted/unflattened/ +10:56 < dammsan> don't recall, but i used of_property_read_u32(node, "cpg-mode", &cpg_mode) in my prototype +10:57 < dammsan> see "[PATCH/RFC] clk: shmobile: DT property SoC <-> CCF interface prototype" +10:58 < dammsan> the idea was to use of_update_property() +10:58 < dammsan> not sure if that applies anymore +10:58 < dammsan> much has changed in 3 years i guess +10:59 < geertu> I think it will work +10:59 < geertu> morimoto: As you coined the MODEMR and ESx.y handling topics, do you have more questions? +11:00 < dammsan> i like removing symbol dependencies myself +11:01 < morimoto> geertu: thanks. it was not urgent. but something process happen, that is enough for me +11:02 < geertu> morimoto-san: Thanks +11:02 < geertu> Topic 3.

Pinged Russell ~2 weeks ago but still no response from him. I he still have not responded early next week I will ping him again. Anyone got tips on how to get his attention? I need his Ack on the ARM part of the series to take the series to the dmaengine tree. +11:07 < neg> Vinod spoke in favor of the dmanegine bits so I'm hoping with Russells Ack this can finaly be taken upstream +11:10 < geertu> neg: Did you get any feedback on the other rcar-dmac series? +11:12 < neg> yes Russell had feedback on v7 +11:14 < geertu> neg: I mean the other series, which I collected in topic/rcar-dmac-niklas +11:14 < neg> or are you talking abut the dmac cleanups? If so Laurent Acked all with a cosmetic missing blank line +11:14 < geertu> OK +11:15 < neg> is on my list to send a v2 collecting his Acks and adding the missing blank line for tomorrow, been focusing to get other work done +11:21 < horms> neg: In general the procedure with Russell is to get his approval then, if the patch is for him to accept, put it in his patch tracker +11:22 < horms> But in general I would suggest politely reposting the series and asking him to help move it forwards +11:22 < geertu> horms: In this case it's for approval, as the patch should go in through vinod +11:22 < horms> ok +11:23 < horms> I think Russell is genearlly quite busy, but reasonable when handled with care +11:23 < neg> horms: so it's better to repost the series then to send a ping to the old thread? +11:23 < horms> I guess its up to you. +11:23 < horms> But I feel a repost might be more likely to get his attention +11:24 < horms> I merged some kexec-tools patches of his recently +11:24 < horms> so hopefully we are in his good books at this time +11:24 < neg> ok thanks then I will repost the series early next week if no response by then +11:28 < geertu> Anything else to report, ask or discuss? +11:28 < horms> Not from here +11:29 < khiemnguyen> About CPUFreq patchset, I will try to send v2 in early July. Sorry for delay... +11:29 < horms> Ok, will that be targeted at v4.9?

Sounds good to me. +<pinchartl> v4.8 will be a bit tight for upstreaming [17:06] +<pinchartl> I'll schedule it for v4.9 +<kbingham> yes, that sounds more feasible. +<pinchartl> next, Magnus [17:08] +<pinchartl> who's not available +<pinchartl> AUDIO-DMAC,?,plan,magnus,IPMMU integration on Gen2 +<pinchartl> AUDIO-DMAC,?,plan,magnus,IPMMU integration on Gen3 +<pinchartl> AUDIO-DMAC,?,plan,magnus,IPMMU support on Gen2 +<pinchartl> AUDIO-DMAC,?,plan,magnus,IPMMU support on Gen3 +<pinchartl> VIN,?,prototype,magnus,IPMMU integration on Gen2 +<pinchartl> VIN,?,prototype,magnus,IPMMU integration on Gen3 +<pinchartl> VIN,?,prototype,magnus,IPMMU support on Gen2 +<pinchartl> VIN,?,prototype,magnus,IPMMU support on Gen3 +<pinchartl> is anyone aware of any progress there ? +<pinchartl> I'll take that as a no :-) [17:09] +<neg> I know he started to look at VIN+IPMMU not sure how far he got [17:10] +<pinchartl> we don't have a "started looking at but not sure" status, I'll + leave it as-is :-) +<pinchartl> next, Morimoto-san [17:11] +<pinchartl> RSND,v4.10,public,morimoto,DT bindings for graph sound +<pinchartl> RSND,v4.10,public,morimoto,dw-hdmi-i2s-audio prototype on Gen3 +<pinchartl> RSND,v4.10,prototype,morimoto,HDMI SSI prototype on Gen3 +<pinchartl> RSND,v4.10,plan,morimoto,HDMI sound Upstream support without + hotplug on Gen2 +<pinchartl> RSND,2016-09-30,plan,morimoto,Hotplug support upstream on Gen3 +<morimoto> My ALSA + HDMI patch-set are +<morimoto> 1) cleanup patches [17:12] +<morimoto> 2) OF graph patches +<morimoto> 3) OF graph base new sound card patches +<morimoto> 4) HDMI sound driver patches +<morimoto> I posted 1) and 2) +<morimoto> 1) is slow progress +<morimoto> Maintainer said 2) is OK for him, but he want to see 3) [17:13] +<morimoto> So, 2) and 3) will be merged and posted in next time +<pinchartl> nice +<morimoto> But, I don't know how to handle it on each Maintainer [17:14] +<morimoto> I'm asking it now +<pinchartl> ok +<morimoto> I asked about 2) to you pinchartl :) +<morimoto> about port vs endpoint on video/sound +<morimoto> not a big deal, but DT change after formal is difficult ? [17:15] +<pinchartl> I know +<pinchartl> I haven't had time to review the patches yet +<pinchartl> I'll try to do it this week but I can't promise +<morimoto> OK +<morimoto> that's it from me [17:16] +<morimoto> Maybe we can talk about it on MiniPeriCon ? +<pinchartl> that's a good idea [17:17] +<morimoto> Thanks +<pinchartl> next, Niklas +<pinchartl> ADV7482,v4.7,public,niklas,Prototype on Gen3 [17:18] +<pinchartl> ADV7482,v4.9,plan,niklas,Gen3 support upstream +<pinchartl> ADV7482,v4.9,plan,niklas,Interlace support upstream +<pinchartl> VIN,v4.7,public,niklas,CSI2 prototype (Gen3) +<pinchartl> VIN,v4.8,public,niklas,Gen3 support +<pinchartl> VIN,v4.8,plan,niklas,Scaler support (on Gen3 +<pinchartl> VIN,v4.9,plan,niklas,CSI2 interlace support upstream (Gen3) +<pinchartl> VIN,v4.9,plan,niklas,CSI2 support upstream (Gen3) +<pinchartl> VIN,v4.9,plan,niklas,Gen3 support upstream (without CSI-2) +<neg> easy this time, no progress so far. Hope to have a new VIN patchset with + UDS support done before I leave for Tokyo [17:19] +<pinchartl> ok [17:21] +<pinchartl> for VIN,v4.8,public,niklas,Gen3 support +<pinchartl> should that be moved to v4.9 ? +<neg> yes since I think we need to figure out what/if to extend v4l2 to + support the ADV7482 first [17:22] +<pinchartl> and regarding No progress, will hopefully be implemented before + PeriPeriCon. [17:23] +<pinchartl> oops +<pinchartl> ADV7482,v4.7,public,niklas,Prototype on Gen3 +<pinchartl> VIN,v4.7,public,niklas,CSI2 prototype (Gen3) +<neg> or do you think there is value to try and get driver up as soon as + possible that only works with a 1 output version of the adv7482? +<pinchartl> as those are prototype tasks +<pinchartl> they''re complete, right ? +<neg> yes [17:24] +<pinchartl> thanks [17:25] +<pinchartl> for Gen3 support I don't think we need to rush the merge +<pinchartl> it's likely too late for v4.8 already anyway [17:26] +<pinchartl> I'll move the scaler to v4.9 too [17:27] +<pinchartl> next, Ulrich +<neg> thanks +<pinchartl> DU,v4.7,plan,ulrich,Atomic API test program +<pinchartl> DU,v4.7,public,ulrich,HDMI output on Gen3 prototype +<pinchartl> DU,v4.7,prototype,ulrich,Test setup with HDMI output to HDMI input + loopback (without EDID) +<pinchartl> DU,v4.7,public,ulrich,EDID generation support for the HDMI + loopback test setup +<pinchartl> DU,v4.9,plan,ulrich,HDMI output on Gen3 upstream +<uli___> the test setup is up on elinux/github [17:28] +<uli___> edid generation will go out today +<uli___> that's it +<pinchartl> do you mean the HDMI loopback test setup ? [17:30] +<uli___> yes +<pinchartl> how about DU,v4.7,plan,ulrich,Atomic API test program ? +<uli___> i moved the wiki pages +<uli___> that's what was missing, iirc +<pinchartl> thanks [17:31] +<pinchartl> and DU,v4.7,public,ulrich,HDMI output on Gen3 prototype [17:32] +<pinchartl> is that considered as complete ? +<uli___> let's consider it as such. [17:33] +<pinchartl> there was also [17:34] +<pinchartl> VIN,v4.8,public,ulrich,Add DV timings support to rcar-vin +<uli___> that has been picked up recently +<pinchartl> nice [17:35] +<pinchartl> by Hans ? +<uli___> i just saw the auto-generated e-mail for the media tree +<pinchartl> then they have been applied by Mauro, perfect +<pinchartl> next, me, messing up the alphabetical order again [17:37] +<pinchartl> DU,?,plan,laurent,IPMMU integration on Gen3 +<pinchartl> DU,?,plan,laurent,IPMMU support on Gen3 (through VSPD+FCP) +<pinchartl> DU,v4.9,plan,laurent,Fix 3 planes formats +<pinchartl> no progress +<pinchartl> VSP,?,plan,laurent,Fixed alpha support (VI6_DPR_*_ROUTE.FXA) +<pinchartl> no progress +<pinchartl> VSP,?,plan,laurent,UDS regression fix [17:38] +<pinchartl> it turns out that this requires implementing image partitioning + support in the VSP driver +<pinchartl> as, unlike the VSP1 in Gen2, the VSP2 in Gen3 can't scale images + wider than 128 or 256 pixels (I have to check for the exact + number) +<pinchartl> so the images must be sliced by software, and the VSP run for each + slice [17:39] +<pinchartl> I'll thus rename the task to "Image partitioning support" [17:40] +<pinchartl> UDS will work out of the box then +<morimoto> pinchartl: about UDS regression, it was VSP driver side issue do + you mean ? [17:41] +<pinchartl> it wasn't a regression [17:42] +<pinchartl> or rather +<pinchartl> it's a hardware regression +<morimoto> Ahh, OK +<pinchartl> that requires significant additional work in the VSP driver +<pinchartl> VSP,v4.8,plan,laurent,Fix suspend/resume crash [17:43] +<pinchartl> this isn't scheduled, I'll remove the target version +<pinchartl> VSP,v4.8,public,laurent,HGO operation mode selection [17:44] +<pinchartl> VSP,v4.8,public,laurent,HGO support upstream on Gen3 +<pinchartl> VSP,v4.8,public,laurent,HGO test application +<pinchartl> no progress +<pinchartl> I hope to send a pull request this week +<pinchartl> but it might be too late for v4.8 +<pinchartl> I'll move it to v4.9 [17:45] +<pinchartl> VSP,v4.8,prototype,laurent,Rotation support +<pinchartl> rotation itself is implemented +<pinchartl> but it also requires image partitioning support for images wider + than 256 pixels [17:46] +<pinchartl> this is a dependency that I wasn't aware of +<pinchartl> I'll thus remove the target version due to the dependency on image + partitioning that hasn't been scheduled yet [17:47] +<pinchartl> VSP,v4.8,public,laurent,V4L2 request API usable prototype [17:48] +<pinchartl> I was hoping to send the latest version Monday last week but got + delayed, partly by the preparation of additional tasks for the + multimedia team for Q3 [17:49] +<pinchartl> and then by being unavailable from Friday to Tuesday +<pinchartl> I'll resume now, the patches should go out today +<morimoto> BSP team want to use latest verion on renesas-driver. [17:50] +<pinchartl> as soon as the patches are out I'll of course send a pull request + to Geert [17:51] +<morimoto> sound gr8 +<pinchartl> that's it for the tasks [17:53] +<pinchartl> Topic 2. Additional '50%' tasks (June) +<morimoto> pinchartl: what is current status of CLU/LUT ? +<pinchartl> merged +<morimoto> nice ! +<pinchartl> - VIN CSI-2 Support Prototype [17:54] +<pinchartl> - ADV7482 Driver Prototype +<pinchartl> - VSP CLU Improvements +<pinchartl> - VSP Rotation Support +<pinchartl> - HDMI Input/Output Loopback for R-Car Gen2 +<pinchartl> - FDP Support on Gen3 +<pinchartl> I believe everything is complete +<pinchartl> except for VSP rotation support +<pinchartl> that is complete for images not wider than 256 pixels +<pinchartl> Topic 3. Additional '50%' tasks (Q3) [17:55] +<morimoto> uli___: what is latest status of HDMI out for ES1.1 issue ? +<pinchartl> (go ahead, we'll move to topic 3 after) [17:56] +<morimoto> pinchartl: sorry +<uli___> still todo... +<morimoto> OK. +<pinchartl> creation of the 50% tasks for Q3 has been delayed [17:57] +<pinchartl> I've submitted the tasks for Ulrich, all others are still under + discussion with Magnus +<pinchartl> due to unforeseen and sad circumstances it didn't go as expected +<pinchartl> uli___: have you received an SoW from Jinzai ? +<uli___> not yet [17:58] +<uli___> for the 50% tasks, that is +<pinchartl> ok +<pinchartl> the two tasks currently planned for Ulrich are [17:59] +<pinchartl> VIN HDMI input EDID +<pinchartl> VIN integration on Gen2 +<pinchartl> for Niklas we have initially discussed the UDS regression fix + [18:00] +<pinchartl> but as it turns out it will require more work than expected it + wasn't a good match +<pinchartl> the current plan is to implement support for one of the currently + unimplemented VSP modules +<pinchartl> the SHP (sharpener) was mentioned [18:01] +<pinchartl> but the hardware isn't fully documented +<pinchartl> and the available source code just programs registers with + parameters passed by upper software layers that are not available + to us +<pinchartl> so we'll likely switch to a different module +<pinchartl> for Kieran and me the situation isn't clear either, I expected + feedback from Magnus today [18:02] +<pinchartl> we'll try to fix this asap [18:03] +<kbingham> Understandable if magnus is away. +<pinchartl> Topic 4. PeriPeriCon & RenesasCon preparation [18:04] +<pinchartl> unless there are questions about the additional tasks for Q3 ? +<neg> I'm good for now :-) [18:05] +<pinchartl> for, for peripericon [18:06] +<pinchartl> s/for/so/ +<pinchartl> we'll discuss multimedia topics on Monday afternoon +<pinchartl> there's no fixed agenda yet +<pinchartl> now is the time to propose topics :-) +<morimoto> I would like to talk about OF graph [18:07] +<neg> extensions to v4l2 to support subdevices with more then one output + pipeline +<pinchartl> anything else ? uli___ and kbingham I know you won't be there, but + are there topics you would like us to discuss ? [18:09] +<uli___> can't think of anything [18:10] +<pinchartl> I'd like to discuss the following topics +<pinchartl> - Second batch of additional tasks for Q3 +<pinchartl> - What are we doing right or wrong, and how can we improve +<pinchartl> - Long-term roadmap +<neg> hum I don't know if this is on the roadmap but if there is plans to + support audio in or CEC from VIN HDMI how that would work. But maybe + that is covered in morimoto topic about OF graph? [18:11] +<kbingham> the current m2m design is limited and seems to prevent pipelined + usage of hw ... but I think that's possibly a topic for linux-media + . But that's the only thing I can think of on my future discussion + lists. +<pinchartl> neg: I might be mistaken but I don't think we have hardware + support for CEC [18:12] +<pinchartl> the target market for Renesas devices isn't exactly consumer + electronics :-) [18:13] +<pinchartl> kbingham: yes, I think that's a topic for linux-media +<pinchartl> I'll write it down as a potential task for the future +<neg> pinchartl: hum ofc CEC is terminated in the adv7482 so it might not be + high on the agenda [18:14] +<pinchartl> ah, ADV7482 has CEC support ? +<pinchartl> good to know +<pinchartl> I'm sure Hans would be interested +<pinchartl> but I don't think Renesas would. we should of course ask +<pinchartl> same for audio input. Morimoto-san, do you know if there's an + interest in HDMI audio input ? [18:15] +<morimoto> Yeah, of course +<morimoto> Oops, +<morimoto> Do you mean BSP request ? +<morimoto> BSP team doesn't have such request at this point. [18:16] +<pinchartl> either an existing BSP request, or something that would be of + interest to them in the future +<pinchartl> same for HDMI CEC support, is there an interest ? +<morimoto> but it seems they are starting about HDMI support for customer +<morimoto> I can say BSP team is stating about "HDMI" only, they don't know + detail of it :) [18:17] +<pinchartl> ok +<morimoto> So yes, in the future, they will request such detail feature +<pinchartl> we can discuss that during RenesasCon [18:18] +<pinchartl> I'll send out the list of topics for PeriPeriCon in the meeting + report, if anyone wants to add topics to the agenda it will still + be possible until the end of the week +<pinchartl> Morimoto-san and Niklas, could you each prepare a very brief + presentation for the topic you proposed for the meeting ? + [18:19] +<pinchartl> it should be 5 minutes long at most +<pinchartl> just to get everybody on the same page to start discussions +<morimoto> on email ? or here ? +<pinchartl> no, for PeriPeriCon [18:20] +<neg> will do +<morimoto> OK, will do +<pinchartl> thank you +<pinchartl> regarding RenesasCon +<pinchartl> I propose finalizing the preparation for it during PeriPeriCon +<pinchartl> Renesas is driving the agenda there [18:21] +<pinchartl> but it will be a good occasion to ask questions +<pinchartl> for instance regarding HDMI audio input and CEC +<pinchartl> I will also prepare a presentation of the multimedia group + activities [18:22] +<pinchartl> neg: I've seen the slides you've sent, thank you +<pinchartl> morimoto: do you think we need a detailed presentation from each + developer, or a single summary presentation of our activities ? + [18:23] +<neg> I hope they are on the right level for the event. Thanks morimoto for + your comments! +<morimoto> pinchartl: it up to you :) I can say it is free style [18:24] +<morimoto> neg: no problem :P +<morimoto> basically, 1 person has 10min. style is free [18:25] +<morimoto> BTW, I created Wiki page for MiniPeriCon and RenesasCon [18:26] +<morimoto> + https://osdr.renesas.com/projects/linux-kernel-development/wiki#PeriPeriCon +<morimoto> We can use it +<morimoto> +<pinchartl> thank you +<pinchartl> I think that's it then [18:27] +<pinchartl> the next multimedia meeting will be during PeriPeriCon +<morimoto> sounds nice :) +<pinchartl> and the one after that will be on Wednesday two weeks later, I'll + send an invite +* kbingham wishes he was going to Japan :) [18:28] +<pinchartl> kbingham: it's not too late to book a plane ticket ;-) +<neg> I have a practical question for peripericon and renesascon, do anyone + plan to bring a HDMI->VGA adapter incase we find an old beamer :-) +<morimoto> kbingham: can we meet on Oct ELCE ? +<kbingham> morimoto: Of course :) I'll be at ELCE +<kbingham> pinchartl: It's not the ticket preventing me from going to japan + next week :) [18:29] +<morimoto> Oops, we need projector on MiniPeriCon ?

The answer was yet. +11:01 < geertu> It can take a while for VAT numbers to appear in all databases... +11:01 < horms> I asked, "really?". The answer was yes. +11:02 < horms> right, that seems like the most likely explanation +11:02 < horms> the magic web site now says my eori number is valid +11:02 < horms> which is new +11:02 < horms> so perhaps that is enough +11:02 < horms> I am trying to confirm that +11:03 < morimoto> horms: my email which from shipping guys said +11:03 < morimoto> you didn't have "VAT deferment license", but if you have EORI you can receive +11:03 < horms> ok +11:04 < morimoto> Hmm.. mystery +11:04 < morimoto> neg: sorry for interrupt your report +11:05 < neg> morimoto: np, I did not have much to repoert anyhow and feel I got that out :-) +11:06 < morimoto> your one will be forwarded from magnus +11:06 < geertu> Thanks Niklas. +11:07 < geertu> Finally, Khiem. +11:07 < khiemnguyen> A) Nothing yet. +11:07 < khiemnguyen> B) Try to catch the kernel v4.9 for CPUFreq. +11:07 < khiemnguyen> I wonder how much time is remained, 2 weeks ? +11:07 < khiemnguyen> C) +11:08 < khiemnguyen> Some additional work are assigned. +11:08 < khiemnguyen> I'm struggling to find time for upstream work. +11:08 < khiemnguyen> That's all for now. +11:09 < khiemnguyen> Please advice how much time is remained :) +11:09 < geertu> Less than two weeks. +11:09 < geertu> One week for changes to the dts(i) +11:10 < khiemnguyen> geertu: I see. Let's me try to push the patches this week or early next week. It's my last chance, I think. +11:10 < khiemnguyen> s/Let's/Let +11:14 < horms> good plan +11:15 < geertu> Yep. +11:15 < geertu> Thanks Khiem! +11:15 < geertu> Topic 2. r8a7792/Wheat board is being/has been added to mainline +11:15 < geertu> I guess the recurring issue is board documentation? +11:15 < geertu> and board access +11:17 < geertu> horms: Anything particular you wanted to discuss? +11:17 < horms> we have the boot size issue, but perhaps that is best discussed on the periperi ml +11:17 < geertu> I mean about r8a7792/wheat +11:18 < horms> no, not that i can think of +11:18 < geertu> Topic 3. r8a7795/H3ULCB board is pending: Cogent seems to have prioritised +11:18 < horms> documentation is always nice :) +11:18 < geertu> Topic 3. r8a7795/H3ULCB board is pending: Cogent seems to have prioritised Wheat +11:19 < horms> I guess thats their call +11:19 < horms> they were on my case to move h3ulcb +11:19 < horms> but about the same time that I got the green light from Renesas they moved onto something else +11:20 < horms> so i guess its not going to appear in v4.9 +11:20 < morimoto> I think I sent ulcb info to EuroPeri ? +11:20 < morimoto> I think we can have few ulcb board 9/E. +11:21 < geertu> morimoto: Yes, I got the docs, thanks for that! +11:21 < morimoto> geertu: np +11:21 < morimoto> I will ask to Magnus for remove access. +11:21 < morimoto> s/remove/remote/ +11:21 < geertu> Magnus said a while ago he already has a Blanche. +11:22 < geertu> And I believe he also has an RSK? +11:22 < morimoto> geertu: I don't know about his RSK +11:23 < shimoda> horms: about h3ulcb, if renesas japan needs to merge it into v4.9, what we should do? +11:24 < horms> shimoda: ok, if its important I think we have two options +11:24 < horms> 1) rework the patches a bit ourselves +11:24 < horms> 2) put some pressure on cogent, perhaps via artemi +11:24 < horms> I have tried to encourage Sergei to do something but he is quite resistant to encouragement from me +11:25 < horms> option 1 implies someone has access to a board for testing +11:25 < shimoda> horms: ok. goda-san consider about this board to upstream. so, 3) goda-san (and munakata-san?) put some pressure on cogent too :) +11:26 < morimoto> From munakata-san can be nice pressure :) +11:26 < horms> Yes, that is what I meant by 2) +11:26 < horms> I'm sure Cogent can do something if pressure is applied in the right place +11:27 < horms> to be clear all I would like is for the patches to be split up (and of course re-tested) +11:27 < horms> And I would like to merge the patches by next Wednesday. So probably they need to be posted a bit earlier than that to allow some review etc... +11:28 < shimoda> horms: i got it. i prefer 2). so I will forward this infor to goda-san. +11:28 < horms> ok. let me know if you need any support. +11:29 < shimoda> horms: ok. thanks! +11:29 < geertu> Topic 4. Renesas would like to know the kernel size issue on upstream. +11:29 < geertu> You think this is best suited for the ML? +11:31 < horms> We can cha here if you prefer +11:31 < horms> But really I think we need a way to allow the mainline defconfig to keep working so we can test it +11:31 < horms> That can be without inird if necessary, so we still have some space to play with +11:32 < horms> But probably it will keep growing +11:32 < horms> And unless other vendors, who actually use mainline, have a 16MB limit we will be carring a very heavy burden to try to keep the defconfig below that limit. e.g. using modules +11:32 < horms> So I would like to know if it is practical to boot the kernel at a different location +11:33 < geertu> If it's just about testing arm64 defconfig, to catch issues caused by the presence of foreign drivers, you can always boot using a smaller kernel, and kexec into the large one +11:33 < horms> hmmm, good point +11:34 < horms> but really is it too much to ask for things to work out of the box? +11:34 < horms> perhaps it is +11:34 < horms> kexec may be a good work-around +11:34 < horms> as i understand things the limitatino we have is +11:34 < horms> that the kernel is unpacked at 0x4800 0000 +11:35 < horms> and uboot us at 0x4900 0000 +11:35 < horms> so if the kernel is too big it overwrites u-boot +11:35 < horms> presumably that is not a problem when kexecing as uboot is long out of the picture +11:35 < horms> is that correct? +11:36 < geertu> Yes +11:36 < geertu> I've used kexec to boot multi_v7_defconfig on e.g. armadillo +11:36 < horms> Ok, probably Magnus needs to be involved in this discussion. +11:36 < horms> But it may be a good option. +11:37 < geertu> Still, our downstream users will not use arm64 defconfig for products +11:37 < geertu> So providing a renesas64_defconfig somewhere makes sense +11:38 < geertu> A disadvantage is that it needs to be maintained +11:38 < horms> I understand that +11:38 < horms> but yes, i see the downside too +11:38 < horms> and frankly its 1/2 a step away from upstream first +11:38 < horms> Perhaps I am overreacting +11:39 < geertu> Well, upstream first usually does't apply to defconfigs +11:39 < geertu> Esp. not for embedded. +11:40 < horms> ok, I'll just say that I think its nicer if it does. But perhaps its not practical if arm64 only has one defconfig. And I need to just move on. +11:40 < horms> Certainly I think kexec could be a solution for testing the defconfig +11:40 < horms> And we could consider maintaining renesas64_defconfig out of tree +11:41 < horms> e.g. in the renesas tree but not mainline itself +11:41 < horms> shimoda: how do you feel about this? +11:42 < shimoda> horms: renesas64_defconfig is good to me +11:42 < horms> ok, lets raise this with Magnus then +11:43 < shimoda> but about kexec, it is complex to me :) +11:44 < horms> yes, that is the down side +11:44 < horms> and as a bonus booting will take evern longer remotely +11:45 < horms> but I think the gernal idea would be to bake two kernels +11:45 < horms> 1 small one, possibly with an initrd certainly with kexec +11:45 < horms> boot into it, transfer the second image, say using tftp of something tcp based when operating remotely +11:46 < horms> then kexec -l Image --dtb xyz.dtb; kexec -e +11:46 < horms> More moving parts +11:46 < horms> more things to go wrong +11:46 < horms> but probably it could be made to work +11:47 < geertu> For normal development, you can still use the small config +11:47 < horms> for me my normal work is mostly testing mainline defconfig is still working +11:47 < geertu> I usually use a per-board config anyway +11:47 < geertu> But regularly test shmobile_defconfig on koelsch, and arm64 defconfig on salvator-x +11:48 < horms> ok, i take your point +11:48 < geertu> multi_v7_defconfig is just too big to boot on anything these days +11:48 < horms> for actually development work that makes sense +11:48 < horms> i regard that config as being of theoretical use to Arnd rather than practical use to anyone +11:49 < horms> Anyway, I will see about looking into this as part of my existing work on kexec +11:49 < horms> because I need to do something like this for that work anyway +11:49 < geertu> And on arm64 we only have the config for theoretical use ;-) +11:49 < horms> right, sadly I think I will have to agree with you there +11:50 < horms> which would remove my main objection +11:50 < geertu> BTW, do you need the --dtb option of kexec? +11:50 < geertu> root@koelsch:~# cat $(type -p tftp-kexec ) +11:50 < geertu> #!/bin/bash +11:50 < geertu> IMAGE=zImage +11:50 < geertu> set -e +11:50 < geertu> ( echo verbose; echo get $(hostname)/$IMAGE /tmp/$IMAGE ) | tftp ayla +11:50 < geertu> kexec -l /tmp/$IMAGE --append="$(cat /proc/cmdline)" +11:50 < geertu> kexec -e +11:50 < geertu> root@koelsch:~# +11:51 < geertu> That's what I use +11:51 < horms> Ok, good to know that works +11:52 < horms> I'll see if it can be done on arm64 too +11:52 < horms> does your image have the dtb appended? +11:52 < geertu> No +11:52 < horms> if not I guess its extracted from the running kernel somehow +11:52 < geertu> Yes, that's what I thought, too +11:53 < horms> I do see some value to explictly providing a dtb +11:53 < horms> but I'll look into why what you have above works +11:54 < geertu> IIRC, it doesn't work with the kexec binary in Magnus' initrd. +11:54 < geertu> My userland is Debian NFS root +11:54 < horms> me too +11:54 < horms> i'm unsurprise that kexec binary doesn't work +11:54 < horms> it must be ancient by now +11:55 < geertu> I think it's time to conclude +11:56 < geertu> (and unpack the M3-W ;-) +11:56 < morimoto> :) +11:56 < shimoda> good luck! :) +11:57 < horms> enjoy + bye +11:57 < geertu> Thanks for joining, and have a nice continued day! diff --git a/wiki/Chat_log/20160831-mm-chatlog b/wiki/Chat_log/20160831-mm-chatlog new file mode 100644 index 0000000..01be483 --- /dev/null +++ b/wiki/Chat_log/20160831-mm-chatlog @@ -0,0 +1,384 @@ +Multimedia-chat-meeting-2016-08-31 + +10:05 < pinchartl> topics for the day +10:05 < pinchartl> 1.

No review on VIN GEN3 patches I don't think they will make it to v4.9 :-( +10:35 < pinchartl> regarding HGT +10:36 < pinchartl> I had a look at the RGB to HSV transformation +10:36 < pinchartl> the test application that generate frames is able to compute S and V exactly +10:36 < pinchartl> but for H it differs from the hardware values by 1 at most, in ~8% of the cases +10:37 < pinchartl> you've asked Morimoto-san to check if we can get information about how the hardware performs the transformation +10:37 < morimoto> About your question about RGB <-> HSV, I think I replyed answer. Does it OK for you ? +10:37 < pinchartl> and he replied that the BSP team has no information about it +10:37 < pinchartl> I'm not surprised, as it's a hardware-related question :-) +10:38 < pinchartl> do you think we could get information from the hardware team ? +10:39 < morimoto> The Document issue S vs V is under HW team control now. +10:39 < pinchartl> S and V are fine. it's H that we have trouble with +10:40 < neg> morimoto: yes I understand that precision is lost in RGB->HSV->RGB as the manual states but this is for RGB->HSV which is deterministic. If I use a lookup table for the 8% of values I can not compute the HW is emulated perfectly +10:41 < pinchartl> there's a division by 3 in the equation used to compute H, and I'm pretty sure the hardware approximates that by a multiplication followed by a shift (probably *341/1024 or *683/2048) +10:41 < pinchartl> but even with that we haven't been able to achieve a perfect match +10:41 < neg> so it's the way I calculate RGB->H that is wrong and if possible I would like input on +10:42 < pinchartl> neg: I wouldn't say it's wrong. the issue is that the hardware performs approximations and rounding in a way we don't know +10:44 < geertu> neg: How big are the absolute errors? E.g. can't you just allow -1/+1 differences? +10:44 < pinchartl> geertu: when comparing images, sure, but when computing histograms it can cause an unknown amount of pixels to fall into another bucket +10:45 < neg> geertu: the error is in the range +/- 1 but it's used to generate a histogram with buckets and that error results in a value being counted in the wrong bucket unfortunatly +10:46 < neg> alsa this is only for the test application, so one workaround is to only test it using 1 out of 6 buckets +10:46 < geertu> Can multiple values end up in the same bucket? or is it one-to-one? +10:46 < neg> multiple values can go in the same bucket +10:47 < pinchartl> the histogram generator puts pixels in buckets and reports the number of pixels in each bucket (roughly) +10:47 < neg> there are in total 6 buckets wich can be spread out over a value range of 0-255 +10:48 < geertu> If the test software uses one-to-one buckets, it can calculate upper and lower bounds for each hardware bucket, assuming a max error of -1/+1 +10:48 < pinchartl> geertu: I don't see how that would help +10:49 < pinchartl> a -1/+1 error can cause a pixel to fall in the next bucket +10:49 < geertu> i.e. sum (sw_bucket[first..last]) <= hw_bucket <= sum(sw_bucket[first-1..last+1]) +10:49 < geertu> And the total sum must match +10:49 < pinchartl> in the worst case all pixels could fall in another bucket +10:50 < pinchartl> the purpose of the test is to verify that the driver works correctly. if we have to accept 100% errors, it's quite pointless +10:50 < geertu> Sure, but only due to a -1/+1 difference, right? +10:51 < pinchartl> still +10:51 < pinchartl> we want to catch things like an off-by-one write to registers +10:51 < pinchartl> which would result in pixels falling the another bucket the same way than the H computation error would +10:52 < geertu> In that case you do need to know exactly how the hardware works +10:52 < pinchartl> that's my point, yes +10:52 < pinchartl> anyway, Morimoto-san, if we can get information from the hardware team about how the hardware computes the H value from the R,G,B values, then we'll be able to test the HGT +10:53 < neg> geertu: we know how the HW works for S and V only H still eludes me :-) +10:53 < pinchartl> otherwise we won't be able to catch HGT regressions in the test suite +10:54 < pinchartl> neg: regarding the deadlines +10:54 < pinchartl> you mentioned that tests should be done tomorrow +10:54 < pinchartl> but, first of all, the due date is September the 4th +10:54 < pinchartl> and it's only the description of the test environment that's needed +10:55 < pinchartl> not the full test suite +10:55 < morimoto> OK, I will find HW guy, and will ask. +10:55 < pinchartl> i.e. the list of the test tools +10:55 < morimoto> I can say it will be long term. +10:55 < pinchartl> so that Jinzai can cross-compile them already +10:55 < neg> pinchartl: ohh I thought the entier test suite should be done +10:56 < pinchartl> morimoto: thank you. if we can get the verilog code corresponding to the H computation, I can find out how the hardware works myself ;-) +10:56 < morimoto> pinchartl: OK +10:56 < pinchartl> neg: test scripts can still be modified until the final due date +10:56 < neg> but if they need to compile the tools now this still needs to be done since this is in the gen-image test tool of vsp-tests +10:57 < pinchartl> they can recompile the test tools when performing tests +10:57 < neg> ahh great +10:57 < pinchartl> what they want to avoid is running into cross-compilation issues at the last minute +10:57 < pinchartl> a git pull && make, if there's no additional dependency, is fine +10:58 < neg> I take it from this discussion that it's better for me to submit a vsp-tests that only uses 1 bucket over bundeling the 54M lookup table and use all 6 buckets? Atlest untill we figure out how the HW works +10:59 < pinchartl> yes, please +10:59 < neg> good +11:00 < pinchartl> kbingham: you're next +11:00 < neg> About VIN Gen3, please find time to review it :-) +11:00 < kbingham> VSP-Partitioning Status +11:00 < kbingham> Initial prototype for partition algorithm implemented, work in progress to debug some issues, and get some real testing going. +11:00 < kbingham> Ongoing Plan: +11:00 < kbingham> After a little bit of catch up from being on holiday, my plan is to work on progressing the VSP partitioning, and get some viable tests going. Then of course solve all the bugs that will inevitably pop up. +11:02 < kbingham> If you need me to look at FDP1 stuff anytime - let me know, as I'll focus on VSP for the moment. +11:02 < pinchartl> thanks +11:02 < pinchartl> let's focus on the VSP, yes +11:02 < pinchartl> I'll post my current version of the FDP patches +11:03 < pinchartl> no issue or blocker ? +11:04 < morimoto> pinchartl: could you get M3 board ? and forwarded it to kbingham ? I would like to know +11:04 < kbingham> none at the moment - as I've not got very far yet with being back. Various accountant things and email catch up took up most of yesterday. but I can actually boot a board today :D +11:05 < pinchartl> morimoto: not yet, it's currently in a plane from Tokyo to Helsinki according to the shipment tracking page. it should land in the afternoon +11:05 < morimoto> Ahh, OK. Thank you +11:06 < pinchartl> morimoto: your turn :-) +11:06 < morimoto> OK +11:06 < morimoto> RSND,v4.10,public,morimoto,DT bindings for graph sound +11:06 < morimoto> +11:06 < morimoto> this is on going. it need many steps. +11:07 < morimoto> but it have small steps now. +11:07 < morimoto> RSND,v4.10,public,morimoto,dw-hdmi-i2s-audio prototype on Gen3 +11:07 < morimoto> I posted this patch to ML, and I think it is OK +11:07 < morimoto> but maintainer had summer vacation, and it seems forgot about this +11:07 < morimoto> RSND,v4.10,prototype,morimoto,HDMI SSI prototype on Gen3 +11:08 < morimoto> This works in my local envilonment on old kernel. +11:08 < morimoto> It doesn't work on latest geert's branch, because of above HDMI out issue. +11:08 < morimoto> HDMI sound is based on HDMI video +11:09 < morimoto> RSND,v4.10,plan,morimoto,HDMI sound Upstream support without hotplug on Gen2 +11:09 < morimoto> RSND,2016-09-30,plan,morimoto,Hotplug support upstream on Gen3 +11:09 < morimoto> Is is big topic +11:09 < morimoto> ALSA SoC framework should be cleanup/update +11:09 < morimoto> This is related to unbind issue too +11:10 < morimoto> I posted this topic to ML, and we had discussion +11:10 < morimoto> And I posted cleanup patches. +11:10 < morimoto> 1 series was accepted. but other was NACK:ed by Lars +11:11 < morimoto> I think I and Lars and maintainer (= Mark) want to talk F2F (?) +11:11 < morimoto> EOT +11:11 < pinchartl> thank you +11:11 < pinchartl> regarding the HDMI output issue with the latest renesas drivers tree +11:12 < pinchartl> you mentioned in your e-mail that you would like to know the plan +11:12 < morimoto> Yes, is this Ulrich's task ? +11:12 < pinchartl> we've discussed this earlier, Ulrich will check if we can just increase the default CMA area size without requiring the DT patch +11:12 < pinchartl> uli___: is my understanding correct ? +11:12 < uli___> yes +11:13 < pinchartl> thanks +11:13 < morimoto> OK, nice. I thought it (= prototype) was his task, but after that it is Laurent's task. +11:13 < morimoto> OK, uli___ has this handle +11:15 < morimoto> no more comment form me +11:15 < morimoto> s/form/from/ +11:15 < pinchartl> morimoto: will you attend ELCE ? +11:16 < morimoto> Yes +11:16 < morimoto> Lars has presentation about this topics +11:16 < pinchartl> it would be good to schedule a face to face discussion with Lars +11:16 < morimoto> I think so +11:16 < pinchartl> I'm not sure if his presentation will address this specifically +11:17 < pinchartl> I think he will talk, among other things, about the current mess with the Intel audio hardware +11:17 < pinchartl> (i.e. no Linux support for audio on latest Intel platforms) +11:18 < morimoto> interesting +11:18 < pinchartl> could you contact Lars to schedule a meeting ? +11:19 < morimoto> no. I think I can find him on ECLE ? or should I ask to him ? +11:19 < pinchartl> please ask him beforehand, everybody is busy during ELCE, and this is important enough to make sure we can allocate enough time for the discussion +11:20 < morimoto> OK, will do +11:20 < pinchartl> thank you +11:21 < pinchartl> next, me +11:21 < pinchartl> since last meeting +11:21 < pinchartl> vacation :-) +11:22 < pinchartl> I've submitted IPMMU + DU integration patches +11:22 < pinchartl> they have been tested on Gen2 only due to the IPMMU being broken on H3 +11:22 < dammsan> pinchartl: on ES1 =) +11:22 < pinchartl> the patches include DT integration and changes to the FCP, VSP and DU drivers to make it all work +11:22 < pinchartl> dammsan: yes, ES1.0 :-) +11:23 < pinchartl> I've also reworked Kieran's FDP driver and will post a v2 +11:23 < dammsan> pinchartl: it seems the integration stuff is somewhat experimental, is that correct? +11:23 < pinchartl> which fixes several issues but breaks overalll operation :-) +11:23 < pinchartl> yes, it's experimental +11:23 < dammsan> cool, thanks +11:23 < pinchartl> the DT part should be quite stable +11:24 < pinchartl> changes to the FCP, VSP and DU drivers is experimental +11:24 < pinchartl> I'd really appreciate a careful review +11:24 < pinchartl> not so much for the implementation itself, but for the APIs between the drivers +11:24 < dammsan> right +11:26 < pinchartl> for the next two weeks +11:26 < dammsan> the DT part does not seem to change so much =) +11:26 < pinchartl> no, the DT part is quite stable I think +11:26 < dammsan> hehe +11:26 < pinchartl> there's no new Dt binding +11:26 < dammsan> that's a good thing +11:27 < dammsan> but we do want a stable implementation too =) +11:27 < dammsan> but it begins with a review +11:27 < pinchartl> definitely :-) +11:27 < pinchartl> for the next two weeks +11:27 < pinchartl> - Continue working on the FDP driver to get it merged upstream +11:27 < pinchartl> - VSP image partitioning support +11:27 < pinchartl> - DU and VSP integration on H3 +11:27 < pinchartl> - VIN and HDMI output patch review +11:28 < pinchartl> blockers and issues +11:29 < pinchartl> Geert pointed out, when reviewing the DU and VSP DT integration patches, that the latest Gen3 errata removed VSPD3 +11:29 < pinchartl> the DU3 channel is now fed by VSPD0, as is the DU0 channel +11:30 < dammsan> this is true for both H3 and M3-W? +11:30 < pinchartl> no, only for H3, M3-W has 3 DU channels only (DU0 to DU2) +11:30 < pinchartl> not only does this not match my experience with H3 ES1.0 on which I've used VSPD3 with DU3 successfully +11:30 < pinchartl> but it would also completely break the whole VSP + DU software model +11:31 < pinchartl> I think I've politely mentioned "brain-dead design" when replying to the e-mail +11:31 < pinchartl> I'd like to get more information about this +11:31 < dammsan> that's very polite of you =) +11:31 < pinchartl> and how it's supposed to work +11:33 < dammsan> there may be some sort of reason behind all this +11:33 < pinchartl> morimoto: do you think I could bother you to get more information about this ? +11:33 < dammsan> if it makes sense or not is a different question +11:34 < pinchartl> first of all, whether the errata is correct or not +11:34 < pinchartl> whether it applies to H3 ES1.1 only or ES1.0 too +11:34 < pinchartl> and how DU0 and DU3 are supposed to be operated if they use the same VSPD +11:35 < dammsan> right +11:35 < morimoto> Can you email it me ? I can ask to HW guys. +11:36 < pinchartl> sure, thanks +11:36 < pinchartl> I'll explain that in the meeting report +11:36 < pinchartl> would you like a separate e-mail ? +11:36 < morimoto> meeting report is OK +11:36 < morimoto> Is this for HW team ? or BSP team ? +11:36 < pinchartl> thank you +11:36 < pinchartl> that's all for me +11:36 < pinchartl> Topic 2. Additional tasks for Q3 2016 +11:36 < pinchartl> ------------------------------------- +11:37 < pinchartl> we need to start thinking about additional tasks +11:37 < pinchartl> obviously specific requests from Renesas should be taken into account +11:37 < pinchartl> but we can also be proactive and propose tasks for areas that we have identified as needing love +11:37 < pinchartl> I would thus like feedback from all of you about this +11:38 < pinchartl> if you already have ideas please mention them now +11:38 < pinchartl> otherwise, please think about it this week and propose them by e-mail +11:38 < pinchartl> and just talk to me on IRC +11:38 < dammsan> M3-W DU prototype +11:39 < dammsan> M3-W VIN prototype +11:39 < pinchartl> I'll double-check the details, but I think we can skip the prototype stage and go directly to an upstream-ready patch series for M3-W DU +11:39 < pinchartl> for VIN I'll let neg check what makes sense +11:40 < neg> Will check and get back to you +11:40 < dammsan> that sounds nice, but perhaps we can do prototype for first batch and upstream for next +11:40 < dammsan> we don't know what kind of issues that may be lurking +11:40 < dammsan> if you can do upstream-ready directly then that's fine too +11:41 < dammsan> we need HDMI video out support too eventually +11:41 < pinchartl> let me get my M3-W board and then I'll check what makes the most sense +11:41 < pinchartl> but in any case an M3-W DU task makes sense +11:41 < pinchartl> yes +11:41 < dammsan> sounds good +11:42 < dammsan> are we ready for a dma_buf zero copy user space test program? +11:42 < dammsan> from vin via vsp to du +11:42 < pinchartl> I think we're ready to start working on that, yes +11:43 < pinchartl> we still haven't addressed cache management +11:43 < dammsan> how about audio test program, for loopback testing of kHz setting and L-R issues +11:44 < dammsan> i think the cache management requirement actually means that they want to improve performance +11:44 < pinchartl> yes +11:44 < dammsan> and they have some sort of proposal +11:44 < dammsan> which may or may not make so much sense +11:44 < dammsan> but we probably need some base line to begin with +11:45 < pinchartl> we need to come up with a proposal to achieve proper performances +11:45 < pinchartl> whether it requires special cache management is more of an implementation detail +11:45 < dammsan> yes exactly +11:46 < dammsan> it depends on what user space does too +11:46 < dammsan> i think it makes sense to cook up a zero copy test app as counter-proposal +11:47 < dammsan> but perhaps i need to listen to their requirement more +11:47 < pinchartl> :-) +11:47 < dammsan> how long time would a zero copy test app take to implement? +11:47 < dammsan> would it be possible in one "slot" of additional tasks? +11:48 < pinchartl> I think so +11:48 < dammsan> in two weeks something should be doable IMO +11:48 < dammsan> so i hope to figure out some additional task for all memebers sometime soon this month +11:49 < dammsan> this for the first slot of next quarter +11:49 < dammsan> the second slot content can be discussed in Berlin +11:49 < dammsan> i hope to fix the first slot content in middle of September +11:50 < pinchartl> sounds good to me.

M3 ? both ? +10:56 < horms> both +10:56 < morimoto> OK, +10:58 < khiemnguyen> horms: each driver need to be updated, to backup register context. Otherwise, resume will fail. +10:59 < horms> ok. even drivers that can resume on gen2? +10:59 < geertu> khiemnguyen: Wait, so it is a deeper sleeper than s2ram on Gen2? +11:00 < khiemnguyen> geertu: yes +11:01 < khiemnguyen> at suspended state, the board will shutdown, only power of DDR region will be kept. +11:01 < shimoda> khiemnguyen: is it gen3? not gen2. +11:01 < khiemnguyen> and you need one I2C command to set DDR backup mode, before calling S2RAM. +11:02 < khiemnguyen> It's Gen3. +11:02 < khiemnguyen> ....are we talking about Gen3 ? +11:02 < geertu> khiemnguyen: What does suspend to RAM do now? I thought it did the real suspend, but woke up early due to the need to do something with DDR? +11:03 < horms> thats what i thought +11:03 < geertu> "and you need one I2C command to set DDR backup mode, before calling S2RAM." may be an issue, as AFAIK everything is "handled" in core arm64 code by calling into PSCI. +11:03 < morimoto> khiemnguyen: does your comment based on BSP local implementetion ? +11:04 < khiemnguyen> morimoto: yeah +11:06 < dammsan> [1;5Cit's like upstream first, but not +11:08 < khiemnguyen> morimoto: so, for S2RAM, will we support similar S2RAM mechanism, like in Yocto v2.12.0 ? +11:10 < khiemnguyen> or we just enable S2RAM and fix drivers issues, if any +11:10 < pinchartl> (just FYI, I have to leave at 12:30 EEST sharp) +11:10 < geertu> Ok, let's handle this offline (on periperi ML) +11:10 < geertu> Thanks Morimoto-san! +11:11 < morimoto> geertu: thanks +11:11 < geertu> Next (and final) is Khiem: +11:13 < khiemnguyen> a) No update. +11:13 < khiemnguyen> b) Gen3 CPUFreq (Z clk changing) +11:13 < khiemnguyen> I missed v4.9.

I still have some restrictions in my company. Will try to solve it. +11:16 < khiemnguyen> morimoto: you are using git-send-email, right ? +11:16 < geertu> pinchartl: yes it might (it did at Sony Europe, not Sony US) +11:16 < shimoda> khiemnguyen: i have git-send-email setting. so if you need it, please let me know :) +11:17 < khiemnguyen> shimoda: thanks.

Handling differences between R-Car H3 ES1.x and ES2.0 +11:18 < morimoto> khiemnguyen: I never use git-send-email: I'm using Emacs+Wounderlust +11:19 < geertu> The plan has been (for a while) to use "-es1" in the compatible value, cfr. "renesas,sata-r8a7790-es1" +11:19 < geertu> Ideally, these would be added automatically to the DTB, by DT fixup code (which is WIP). +11:20 < geertu> For "renesas,sata-r8a7790-es1", this was added manually, I assume? +11:20 < pinchartl> I assume you mean r8a7795-es1 ? +11:20 < geertu> Now, it seems there are several differences between R-Car H3 ES1.x and ES2.0 +11:20 < dammsan> geertu: yes, it was an earlier trial for ES handling +11:20 < geertu> pinchartl: We don't have any r8a7795-es1 string yet. +11:21 < geertu> We started with DU and VSP +11:21 < khiemnguyen> geertu: will it be long-term solution ? +11:21 < geertu> Now we start to see differences in CPG/MSSR, PFC, ... +11:22 < geertu> khiemnguyen: In the long term, there will be ES2.0 only? +11:22 < geertu> khiemnguyen: But we may want to keep on using our ES1.x boards +11:23 < geertu> The approach we wanted to take was to focus on the most recent ES ("production") only. +11:23 < pinchartl> on the VSP and DU side there will be non-trivial differences between ES1 and ES2 and we'll need to manually update DT +11:23 < geertu> And try to fixup (preferably at runtime) for running on ES1.x. +11:24 < geertu> So for PFC, it looks like the current pfc-r8a7795 is for ES1.x only +11:24 < geertu> Due to the sheer amount of differences, I think the driver should be renamed to pfc-r8a7795-es1.c +11:25 < geertu> and a new pfc-r8a7795.c for ES2 should be added. +11:25 < neg> for PFC I think that is a good idea +11:25 < geertu> For CPG/MSSR, it's the same. +11:25 < horms> Naming convention asside, i think so too +11:25 < horms> but what if any path is there for forwards compatibility +11:26 < pinchartl> is there any estimate regarding the availability of H3 ES2.0 boards ? +11:26 < geertu> horms: if we have DT fixup, it will automatically be forweard compatible, as the DTS will only have "r8a7795" compatible values. +11:27 < horms> ok +11:27 < horms> got it +11:27 < shimoda> i have a question, how to handle if the number of channels differs between ES1 and ES2? +11:27 < geertu> horms: Only at run-time the "r8a7795-es1" would be added (or changed, for PFC and CPG/MSSR) +11:28 < geertu> shimoda: That was going to be my next point :-) +11:28 < geertu> For Multimedia, the differences seem to be in number of channels (DU) or instances (VSP), and their wiring. +11:28 < pinchartl> yes +11:28 < pinchartl> that will need to be manually changed in DT +11:28 < pinchartl> so if we need an -es1 .dtsi anyway +11:28 < geertu> _Adding_ device nodes in DT fixup code is more difficult than _removing_. +11:29 < pinchartl> is there a point in trying to fixup DT automatically at runtime ? +11:29 < geertu> So having r8a7795.dtsi match the latest revision is problematic. +11:29 < geertu> pinchartl: If it's just the number of channels, it's doable. +11:30 < geertu> If the DU<->VSP topology is too complex, it's different... +11:30 < pinchartl> geertu: it's the DU<->VSP topology that changes +11:30 < pinchartl> the number of DU channels in the same +11:30 < pinchartl> but two of them are served by the same VSP instance +11:30 < dammsan> we can also simply deprecate ES1.x DU support +11:30 < geertu> pinchartl: oh, the change in the number of DU channels is for H3<->M3-W? +11:31 < geertu> pinchartl: Can you serve the two DU channels by one VSP on ES1 too? +11:31 < geertu> (pinchartl: You have to go?) +11:33 < pinchartl> yes it's for M3 +11:33 < pinchartl> and no I can't +11:33 < pinchartl> and yes I have to go :-) +11:33 < pinchartl> sorry +11:33 < pinchartl> I'll read the log later +11:34 < geertu> Is there a document that lists the differences between H3 ES1.0, ES1.x (x > 0), and ES2.0? +11:34 < morimoto> It is difficult to understand pinchartl's yes/no, but it is not my English skill ;P +11:34 < geertu> morimoto: Yes, M3-W has less DU channels than H3 +11:35 < morimoto> geertu: let me check +11:35 < horms> s/less/fewer/ +11:35 < geertu> morimoto: No, you cannot serve the two DU channels on ES1 using one VSP +11:35 < geertu> horms: Dankuwel +11:36 < morimoto> geertu: thank you for your translation :) +11:36 < horms> geertu: sorry, that correction is hard wired into my brain through bitter experience +11:37 < geertu> uli___: You need ES checks for HDMI? +11:38 < uli___> yes +11:38 < geertu> uli___: Can it be solved through an "es1" compatible value? +11:38 < uli___> i also need to distinguish between 1.0 and 1.1... +11:38 < geertu> ... "es1.0" and "es1.1" compatible values? +11:39 < uli___> that should do +11:39 < geertu> OK, good to know. +11:39 < geertu> So I think dynamic DT fixup can work for most cases, except for DU/VSP topology +11:39 < geertu> Then, Dirk Behme is worried about boot up performance. +11:40 < morimoto> geertu: I think I can get ES diff sheet. I will send it +11:40 < geertu> Fixing DT takes time (to be measured) +11:41 < geertu> Dirk prefers an API to read PRR, and handle upon that +11:42 < geertu> Or we can use soc_device_register() (see include/linux/sys_soc.h) +11:43 < geertu> Arnd posted a patch to add soc_device_match(), which can match against SoC-specific revision wildcards. +11:44 < geertu> But I take it all of you are slowing falling asleep? ;-) +11:44 < uli___> to me, that sounds better than the other approaches discussed so far +11:45 < geertu> Which one sounds better?

I can talk it on ELCE timing +10:34 < morimoto> And BSP team is now focusing about Audio-DMAC power +10:34 < morimoto> As I asked on PeriPeriML, it is related to DMAEngine behavior +10:35 < pinchartl> please let me know if you would like me to join the discussion during ELCE +10:35 < morimoto> Thank. I'm happy if you can join to it. +10:35 < morimoto> it will be 2nd day, lunch timing +10:35 < morimoto> after Lars's presentation +10:36 < pinchartl> that works for me +10:36 < morimoto> About DMAEngine, rcar-dmac will power ON for Audio-DMAC when sound driver requests DMA channel +10:36 < morimoto> and power OFF when sound driver release it. +10:36 < morimoto> In my driver, it requests channel when .probe timing +10:37 < morimoto> this means, Audio DMAC is always ON +10:37 < pinchartl> right, I've seen your e-mail +10:37 < morimoto> which is correct approach +10:37 < morimoto> ? +10:37 < pinchartl> that's more of a core topic +10:37 < morimoto> Oops +10:37 < pinchartl> but in a nutshell, I think it would be good to optimize power consumption +10:37 < pinchartl> and only keep the hardware powered on when needed +10:38 < pinchartl> the issue there is that you need to call pm_runtime_get_sync() to power the hardware on +10:38 < pinchartl> which can't be called in atomic context +10:38 < pinchartl> and dma_async_issue_pending() needs to be callable in atomic context +10:38 < pinchartl> so to fix this we would likely need to extend the DMA engine API +10:39 < pinchartl> but to get sucha change accepted +10:39 < pinchartl> we need to provide power consumption numbers +10:39 < morimoto> It is not Renesas specific issue, correct ? +10:39 < pinchartl> so we need to measure the extra power consumption caused by keeping the DMA engine powered on while not in use +10:39 < pinchartl> correct +10:40 < morimoto> Actually, I already created above patches. it request/release each times +10:40 < pinchartl> is that changes for the DMA engine driver or for the ALSA driver ? +10:40 < morimoto> Do you think I should post it to ML ? or keep it in my pocket ? +10:40 < morimoto> ALSA driver side only +10:40 < pinchartl> that's the second idea I was going to propose +10:41 < pinchartl> keep powering the DMA engine on in dma_request_channel() +10:41 < pinchartl> (or rather device_alloc_chan_resources()) +10:41 < pinchartl> but move the dma_request_channel() from ALSA driver .probe() to a later point +10:41 < pinchartl> I think those patches would be sense to be posted +10:42 < morimoto> OK +10:42 < morimoto> This means, request/release happen many times. is this correct ? +10:43 < pinchartl> yes +10:43 < pinchartl> well, more than currently at leas +10:43 < pinchartl> t +10:43 < morimoto> OK. nice to know. I can be your father if you want :) +10:43 < pinchartl> I don't think my current father would be happy about that :-) +10:43 < morimoto> hehe :) +10:43 < morimoto> That's it from me +10:44 < pinchartl> what's your plan for the next two weeks ? +10:45 < morimoto> About patches, it is based on Maintenor. +10:45 < morimoto> I need to post more patches, but these are based on current patches. +10:45 < morimoto> If no update on ML, I will do Renesas side task +10:45 < pinchartl> ok +10:46 < pinchartl> thank you +10:46 < pinchartl> next, Niklas +10:46 < neg> a) Posted HGT patches, I see minimal work left to keep them up to date until they can be picked up +10:46 < neg> b) Start to work on VIN for M3 and rebase VIN Gen3 patches +10:46 < neg> c) No review on VIN Gen3 patches +10:47 < neg> also if there is time update the vsp-tests tool to take overlaping HGT hue areas in to account +10:47 < pinchartl> for the HGT, let's sync up on that after the meeting, I'll take your patches in my tree +10:47 < neg> ok +10:47 < pinchartl> I have done so already, probably a slightly different version, that's why we need to sync up +10:48 < pinchartl> regarding the VIN Gen3 patches, they were on my todo list after last meeting, but I had to focus on the VSP :-/ +10:48 < pinchartl> I'll really try to get to them ASAP +10:48 < pinchartl> you had a quick question about what work to aim to include for renesas-drivers releases ? +10:49 < neg> np :-) +10:49 < neg> I have tried to keep the VIN Gen3 patches ready for renesas-drivers but have not always sucseeded in keeping them up to date. And since they seems to be a long way from beeing pickedup I was wondering if I should drop them from the patches I try to get in to renesas-drivers so Geert don't have to deal with any conflicts that series cause. If you see value in having them in renesas-drivers I will rejuvenate +10:49 < neg> my effort to keep them up to date at all times. +10:50 < pinchartl> geertu: any opinion on that ? +10:53 < pinchartl> renesas-drivers is a -next tree that is a bit more agressive than -next. it serves as a way to catch integration (as in merging multiple development branches) issues early +10:53 < pinchartl> including Gen3 VIN support in renesas-drivers is thus useful when you post a new version of the patch series +10:53 < pinchartl> but after that, if it starts generating painful conflicts, it likely means a new version of the series will be needed anyway +10:54 < pinchartl> so I wouldn't insist in keeping the code in renesas-drivers at all times +10:55 < neg> ok, I will continue to try and keep them up to date and included in renesas-drivers then +10:55 < pinchartl> please submit them for inclusion when you post a new version of the patches +10:55 < pinchartl> but don't spend an unnecessary large amount of time keeping them up-to-date between two versions +10:56 < neg> make sens +10:57 < pinchartl> thanks +10:57 < pinchartl> next, uli___ +10:58 < uli___> a) +10:58 < uli___> - kept the salvator hdmi out alive (build failure; want to convert it to soc_device_match() before sending a new revision) +10:59 < uli___> - checked if it works without the funky cma reservation patch (it does, it's sufficient to increase the cma size) +10:59 < uli___> - started looking into gen2 vin integration in earnest (see c) ) +10:59 < uli___> b) finish gen2 vin integration +10:59 < uli___> c) i don't have hardware docs for the gose board +10:59 < uli___> can somebody set me up with those? +10:59 < uli___> [that's it] +11:00 < pinchartl> do you regarding Gen2 VIN integration, that's due for the 18th, so I assume you'll finish it before two weeks ? :-) +11:00 < pinchartl> s/do you // +11:00 < uli___> yes +11:01 < pinchartl> thanks +11:02 < pinchartl> what's the status of DU,v4.9,public,ulrich,EDID generation support for the HDMI loopback test setup ? +11:02 < uli___> that's part of the hdmi in series, i'll send that out with gose support added before the due date +11:03 < pinchartl> perfect, thanks +11:03 < uli___> provided somebody can get me the docs... +11:03 < uli___> morimoto: HINT +11:03 < pinchartl> do you mean the schematics ? +11:03 < uli___> yes +11:03 < pinchartl> do you have a GPG key ? +11:03 < uli___> afraid not +11:04 < pinchartl> can you create one ? :-) +11:04 < uli___> is there an alternative?

But I can't find "UDS" word on todo list +11:22 < pinchartl> that's because there was nothing UDS-specific that had to be done +11:22 < pinchartl> implementing image partitioning fixed it +11:22 < morimoto> OK +11:22 < pinchartl> - VSP,2016-06-30,request,laurent,give information to Renesas about write-back feature plan +11:22 < pinchartl> will be assigned to Kieran as an additional task for the first half of Q4 +11:23 < pinchartl> - VSP,2016-06-30,request,laurent,ES2.0 / M3 update +11:23 < pinchartl> will be handled as part of the DU M3 integration, assigned to me as an additional task for the first half of Q4 +11:23 < pinchartl> - VSP,2016-06-30,request,laurent,update request API on renesas-driver +11:23 < morimoto> About, Write-back, it is next Kieran's task ? +11:23 < morimoto> I can remove it if todo list has it +11:23 < morimoto> correct ? +11:24 < pinchartl> please wait until the task get officially approved :-) +11:24 < morimoto> :) OK +11:24 < pinchartl> I'll then move it from the request file to the todo file +11:24 < pinchartl> - VSP,2016-06-30,request,laurent,update request API on renesas-driver +11:25 < pinchartl> I'll update the patch series before ELCE and send a pull request to Geert for renesas-drivers +11:25 < morimoto> you can handle only todo list, Renesas side will update request file +11:25 < pinchartl> (ok) +11:25 < pinchartl> my plan is to do so before kernel recipes, which is in two weeks in Paris +11:26 < pinchartl> but it might overflow to the week before ELCE +11:26 < pinchartl> at the latest it will be done before ELCE +11:26 < pinchartl> - VSP,2016-06-30,request,laurent,vsp1_pm_suspend() bugfix +11:26 < morimoto> Request API do you mean ? +11:26 < pinchartl> (yes) +11:26 < pinchartl> this has been proposed as an additional task for Q4, but Magnus told me that it needs to be discussed internally in Renesas first +11:26 < pinchartl> - VSP,2016-10-30,request,laurent,VSP cache less support for BSP team +11:27 < pinchartl> this has also been proposed as an additional task for Q4, and will possibly be accepted for the second batch +11:27 < pinchartl> it will be discussed face to face in Berlin first +11:27 < pinchartl> as it's not clear yet how to proceed +11:27 < morimoto> What is the problem about VSP1 PM suspen d? +11:27 < pinchartl> it doesn't work :-) +11:27 < pinchartl> suspend/resume is broken +11:27 < morimoto> Ahh OK +11:28 < pinchartl> it might even crash the kernel, I don't remember exactly +11:28 < morimoto> OK, thanks +11:28 < morimoto> And, I think I sent request about mising format something. +11:28 < morimoto> BSP team created local patch, do you remember ? +11:29 < pinchartl> here's the description of the problem I sent to Magnus +11:29 < pinchartl> The VSP suspend/resume code is known to be broken and needs to be fixed. This is further complicated by the fact that the VSP memory accesses are served by the FCP on Gen3, creating a suspend/resume dependency between the two devices. +11:29 < pinchartl> The VSP suspend/resume problem should be self-contained, but the FCP dependency would require dependencies support in the PM core. Work is ongoing in that area, and I believe we should take a more active role there. This isn't very suitable for additional tasks as they exist today as no deliverable can be guaranteed in a fixed amount of time. +11:29 < pinchartl> It might be possible to work around the problem by using the early/late suspend/resume handlers in the VSP and FCP drivers. I can't guarantee this at the moment without a more detailed and thus time-consuming analysis, hence the prototype status of this task. +11:30 < pinchartl> regarding the missing format +11:30 < pinchartl> was it the tri-planar formats for the DU ? +11:30 < morimoto> Maybe, I forgot detail +11:30 < pinchartl> so did I :-) +11:31 < pinchartl> but triplanar formats support has been merged +11:31 < morimoto> OK, nice +11:31 < pinchartl> any other question regarding the requests ? +11:32 < morimoto> nothing from me. Thanks +11:32 < pinchartl> you're welcome +11:32 < pinchartl> Topic 4.

Please wait +11:34 < kbingham> np. +11:34 < morimoto> Maybe it will be after tomorrow +11:34 < pinchartl> morimoto: I think you can remove "What is the current status of "Rotation + ImagePertition" ?" and "Z-order" from the wiki page +11:34 < pinchartl> Z-order has been merged +11:34 < pinchartl> and patches for rotation + image partition have been posted yesterday +11:34 < morimoto> OK, but BSP team want to check it. keep it and set "finish" is help for me +11:35 < pinchartl> ok +11:35 < morimoto> s/help/helpful +11:35 < pinchartl> Topic 5. Next meeting +11:35 < neg> If possible I would like to talk about more pad aware v4l2 operations to you and Hans duinrg the mini multimedia summit (and to whom ever else is interessted ofc), but for periperi multimedia I think we talked about it in Tokyo +11:36 < pinchartl> neg: that's a good idea. could you propose that by e-mail to Hans ? +11:36 < neg> will do +11:37 < pinchartl> thanks +11:37 < pinchartl> I will attend Kernel Recipes in Paris in two weeks +11:37 < pinchartl> so I won't be available Wednesday-Friday +11:37 < pinchartl> and neither will I be available on Monday that week +11:38 < pinchartl> we could move the meeting to Tuesday, but that would conflict with the core meeting +11:38 < pinchartl> unless we move it one hour earlier, and keep it short +11:38 < pinchartl> another option is to hold the meeting on Wednesday without me +11:38 < pinchartl> thoughts ? +11:39 < morimoto> Wednesday = 28th ? +11:39 < pinchartl> yes +11:39 < neg> short meeting before core works for me, I think you should be in the meeting if possible +11:40 < pinchartl> given that it will be the last one before Berlin, I'd like to attend it, yes +11:40 < pinchartl> we'll keep the status update very short +11:40 < pinchartl> and focus on the agenda for the Berlin meeting +11:41 < pinchartl> so that would be 2016-09-27 at 08:00 BST / 09:00 CEST / 10:00 +11:41 < pinchartl> EEST / 16:00 JST +11:42 < neg> works for me +11:42 < morimoto> I booked +11:42 < uli___> ok +11:44 < pinchartl> thank you +11:44 < pinchartl> that's it for today +11:44 < pinchartl> thank you all for joinin diff --git a/wiki/Chat_log/20160921-io-chatlog b/wiki/Chat_log/20160921-io-chatlog new file mode 100644 index 0000000..3b210f8 --- /dev/null +++ b/wiki/Chat_log/20160921-io-chatlog @@ -0,0 +1,337 @@ +--- Log opened Wed Sep 21 09:27:21 2016 +09:27 -!- wsa_ [~wsa@p5B384463.dip0.t-ipconnect.de] has joined #periperi-io +09:27 -!- Irssi: #periperi-io: Total of 4 nicks [0 ops, 0 halfops, 0 voices, 4 normal] +09:27 -!- Irssi: Join to #periperi-io was synced in 0 secs +09:27 < wsa_> hi guys! +09:29 < khiemnguyen_> hello +09:30 -!- shimoda [~shimoda@relprex3.renesas.com] has joined #periperi-io +09:30 -!- horms [~horms@217.111.208.18] has quit Quit: Leaving +09:30 -!- horms [~horms@217.111.208.18] has joined #periperi-io +09:31 -!- neg [~neg@unaffiliated/neg] has joined #periperi-io +09:32 < morimoto> hi +09:32 < neg> hello everyone +09:32 < shimoda> hi +09:33 < wsa_> morimoto: before we start, can you also keep an eye that either Magnus or you bring me a ZComex AC-180M SDIO card to Berlin? +09:34 < wsa_> I need it for an additional task +09:34 < wsa_> I think Shimoda-san used it for testing +09:35 < wsa_> I already asked Magnus.

+09:58 < horms> I'm ok +09:58 < wsa_> good :) +09:58 < wsa_> neg: I know you don't have anyhthing IO related, but can you tell me if you have time for base task assignments in the near future? +09:59 < neg> I think I should have time for that +09:59 < neg> I do not yet have a base contract for Q4 but other than that it should be fine :-) +09:59 < wsa_> same here:D +10:00 < wsa_> ok, so then let's move on to Geert +10:00 < neg> any particular task you think I should get started on? +10:00 < wsa_> neg: I'll ask Geert in a second ;) +10:01 < wsa_> geertu: your turn +10:01 < geertu> A) What have I done since last time: - SPI slave support v2, http://elinux.org/Tests:MSIOF-SPI-Slave +10:01 < wsa_> (let's see if the alerting for irssi I sent him recently works ;)) +10:01 < geertu> B) What I plan to do till next time: +10:01 < geertu> - No I/O tasks scheduled, but core 64-bit Memory and Ethernet without +10:01 < geertu> Bounce Buffers Prototype, +10:01 < geertu> - Awaiting SPI slave feedback, +10:01 < geertu> - Verify MSIOF SPI functionality on M3-W, if time permits. +10:01 < geertu> C) Problems I have currently: - Nothing I/O related. +10:02 < geertu> First SPI slave feedback is from RobH, who seem to want to revert partly to v1, while I made the changes due to his request ;-) +10:02 < wsa_> heh +10:03 < wsa_> this task: +10:03 < wsa_> SCIF,?,noplan,?,difference in behavior between hardware-assisted flow control and GPIO flow control # Cfr. the thread "[PATCH] sh-sci: fix transition from noflow to HW flow control" +10:03 < wsa_> do you think this could be a investigation suited for a base task +10:03 < wsa_> or is it rather an additional task on its own? +10:03 < geertu> Perhaps I can look into that in the context of the (not yet confirmed) base task +10:04 < wsa_> if you have time... +10:04 < wsa_> ... this is the one where I wondered if neg could have a look if he had interest. +10:04 < geertu> I think it's to be investigated first, whether it's a bug in the driver, on in the serial core. +10:05 -!- horms [~horms@217.111.208.18] has quit Read error: Connection reset by peer +10:05 < geertu> s/on/or/ +10:05 -!- horms [~horms@217.111.208.18] has joined #periperi-io +10:06 < geertu> I have a hardware setup to test it, so perhaps I should just fine some time to bite the bullet +10:06 < geertu> s/fine/find/ +10:06 < wsa_> i see +10:06 < wsa_> makes sense +10:08 < wsa_> i think we are done now?

+10:19 < horms> but one thing that stood out was the NO_SLEEP handling in the BSP +10:19 < horms> which skips sleeping for 10ms on GEN3 +10:20 < horms> Assuming we need such a thing, which at this point seems likely +10:20 < horms> I wonder how it should be handled +10:20 < horms> * Using a NO_SLEEP cap as per the BSP +10:20 < horms> * Using a (new) GEN3 cap (like the GEN2 cap in mainline - which is actually GEN2/3) +10:20 < horms> * Some other way +10:21 < wsa_> NO_SLEEP? gotta check +10:22 < horms> I also noticed that SH_MOBILE_SDHI_SCC_RVSCNTL_RVSEN should be BIT(0) rather than BIT(1). Which clearly should be fixed.

About RZ/G series, it is mass production version of R-Car chip. The reason why it has different naming is business paper work reason (R-Car consortium, etc).

This means WE can control H3/M3. Now we already have "M3" on upstream, even though, M3 press release was not yet happen. But "V3" is not our (= AIS team) product chip. And V3 might not use Linux on it. Don't know detail at this point. So now, we don't know how we control it.

I got NAK from maintainer before... +10:26 < geertu> As changing initcalls and order in drivers/Makefile is always very complicated, I'm thinking of making renesas_soc_init() a core_initcall anyway, and letting soc_device_register() initialize the soc_bus if that hasn't been done yet. +10:27 < pinchartl> anything that touches initcall ordering seems hacky to me, but I'll let others complain this time :-) +10:27 < geertu> If you just call soc_device_register() before soc_bus_register() has happened, it crashes with a nice NULL pointer dereference +10:28 < geertu> Does it still sound reasonable? +10:29 < pinchartl> I've seen worse :-) +10:29 < geertu> One other thing: Do we want to make ES1.x support configurable? +10:30 < geertu> If yes, it may make sense to use separate source files. +10:30 < shimoda> geertu: BSP team wants to be single binary +10:31 < morimoto> single binary, but support ES1.x and ES2.0. correct ? +10:31 < shimoda> if separate source files, we can build a single binary to support both es1 and 2? +10:31 < geertu> shimoda: of course +10:31 < shimoda> morimoto: yes +10:31 < horms> Single binary is a hard requirement from my pov :) +10:31 < geertu> shimoda: I meant, do we want CONFIG_ARCH_R8A7795_ES1? +10:31 < pinchartl> geertu: I believe our long term goal should be to remove it, so I'd like to see the code developed in a way that wouldn't make that too difficult. it doesn't need to be in seperate files for me though +10:32 < geertu> pinchartl: I agree +10:32 < pinchartl> and I'd actually like to consider the opposite of your question as well: do we want to remove CONFIG_ARCH_R8A7795 at some point ? +10:32 < pinchartl> but that's another topic +10:33 < horms> what would be the motivation for removing it? +10:33 < geertu> pinchartl: You mean make it unconditional, hence enabling CONFIG_ARCH_RENESAS enables all Renesas arm64 SoCs? +10:34 < pinchartl> geertu: correct +10:34 < geertu> pinchartl: That's what the arm64 maintainers would like, right? +10:34 < pinchartl> yes +10:34 < horms> probably the current arrangment is partly due to historical reasons +10:34 < horms> i wonder if there is an advantage to keeping the current arrangment +10:34 < pinchartl> I'm not advocating for that, but I believe we should at least consider the option +10:35 < horms> e.g. to allow not carring so many pfc tables in the kernel binary if desired +10:35 < geertu> So your kernel will always include full PFC tables for r8a7795_es1, r8a7795, r8a7796, r8a7797 (I predict that'll be the name of V3M ;-)? +10:35 < pinchartl> kernel bloat is my concern too +10:38 < geertu> OK, let's see later +10:39 < geertu> shimoda: Are H3 ES2.0 boards already available? +10:39 < shimoda> shimoda: not yet, perhaps end of this year or ealry next year +10:40 < morimoto> It will goes to Magnus's remote machine. +10:40 < geertu> shimoda: You said the BSP team will start working on it Oct/M +10:40 < morimoto> Your available board will be next Feb or later ? +10:40 < geertu> So by then we should have something basic ready? But we can't test it? +10:41 < shimoda> geertu: yes. they will start it without actual board :) +10:41 < morimoto> Renesas magic! +10:42 < horms> Do they also code with their eyes shut? +10:43 < geertu> touch typing +10:43 < horms> of course +10:45 < geertu> shimoda: Are you happy with the answer so far? +10:46 < shimoda> geertu: about CPG, i understood it, but about PFC, i don't understand yet +10:47 < shimoda> separate file or into the exist file? +10:48 < shimoda> or we need more discusstion? +10:48 < geertu> shimoda: As the PFC data is quite big, I think separate files are OK +10:48 < geertu> Except if we can actually just use the r8a7796 tables. I have to check if that would cause ill effects. +10:49 < shimoda> geertu: OK. I also think of that. So, I will fowared this infor to the BSP team. Thanks! +10:49 < geertu> Thanks! +10:49 < geertu> Topic 3. R-car hwspinlock driver +10:49 < geertu> Also from Shimoda-san: +10:50 < geertu> BSP team would like to do upstream about the hwspinlock driver for R-Car. +10:50 < geertu> The driver is already merged into the latest Gen3 BSP: +10:50 < geertu> https://git.kernel.org/cgit/linux/kernel/git/horms/renesas-bsp.git/commit/drivers/hwspinlock?h=rcar-3.3.2&id=22d88d4eddb5a0fec485e717a65f218275f6b26b +10:50 < geertu> I don't know the spec of this driver. But, they have concerns about the driver. +10:50 < geertu> - The driver uses "core_initcall" to control PFC driver. +10:50 < geertu> Is it acceptable in Upstream? +10:50 < geertu> - This topic is not related to upstreaming, but the driver cannot handle the CPG driver +10:50 < geertu> because this driver also need the CPG. +10:50 < geertu> Do you think we can upport this driver as well? +10:50 < geertu> Or, do we need an additional task for it anyway? +10:50 < geertu> I checked this BSP patch roughly, and the patch should have a DT doc. +10:50 < geertu> ---end--- +10:50 < geertu> DT doc is commit e4d2c3213280a6985395970cbf26e7ef381dd1d5 +10:50 < geertu> I have two comments here: +10:50 < geertu> 1. The driver uses platform_driver_register() from a core_initcall(). +10:50 < geertu> As the CPG/MSSR driver uses subsys_initcall(), the hwspinlock driver probe will be deferred. +10:51 < geertu> So it will probably be initialized earlier (without deferred probe), if it would use another initcall +10:51 < geertu> it = hwspinlock driver +10:52 < geertu> 2. There are no current users of hwspin in the BSP? What's the plan? +10:53 < shimoda> geertu: about the plan, i don't know. So, I will ask the BSP team later +10:54 < geertu> "the driver cannot handle the CPG driver because this driver also need the CPG/" +10:54 < geertu> Does that mean they woild like to use hwspinlock in the CPG driver? +10:55 < geertu> s/woild/would/ +10:56 -!- horms [~horms@217.111.208.18] has quit [Ping timeout: 244 seconds] +10:58 < shimoda> geertu: this means the hwspin driver calls pm_runtime APIs +10:58 < shimoda> about the driver, I asked BSP team now +10:59 < geertu> OK, thanks! +10:59 < shimoda> this driver will be used if other CPU core (CR7) also runs +10:59 < geertu> IC +11:00 < geertu> Any other topics people want to discuss? +11:00 < shimoda> but, a plan is not clear, they would like to skip upporting of this driver for now +11:02 < geertu> Next meeting will be in Berlin +11:02 < geertu> If you have topics for the meeting, please let me (and periperi) now! +11:02 -!- horms [~horms@217.111.208.18] has joined #periperi +11:02 < geertu> There are already some topics listed at https://osdr.renesas.com/projects/linux-kernel-development/wiki/Miniperi-2016-10 +11:05 < geertu> Nothing to add? +11:06 < geertu> Thanks for joining, and have a nice continued day! diff --git a/wiki/Chat_log/20160927-mm-chatlog b/wiki/Chat_log/20160927-mm-chatlog new file mode 100644 index 0000000..803ac12 --- /dev/null +++ b/wiki/Chat_log/20160927-mm-chatlog @@ -0,0 +1,411 @@ +2016-09-27 Multimedia group chat report + +We had a multimedia group meeting on 2016-09-27.

Test reports from Jinzai +--------------------------------- + +We have received testing reports from Jinzai for the 9/M tasks.

Please make sure you get your patches merged in renesas- +drivers when you send the task report. + +- Missing kernel config options + +Jinzai used the ARM64 defconfig, which is missing support for several of the +our drivers. To avoid such test failures, a proposal to include the kernel +config options required for testing of each task in the report has been +approved. + +A minimal diff against defconfig can be generated with + +make ARCH=arm64 savedefconfig + +and can then be manually filtered to remove unrelated options. + + +Topic 3.

BSP patch mining coordination +-------------------------------------- + +Team leaders have been tasked with mining the BSP for patches and classifying +them based on the subsystem/device/feature they're related to, with a proposed +upstreaming plan for each of them. Morimoto-san has already posted a list to +the Renesas wiki, and Simon got his own list too. + +To avoid work duplication, we will use Simon's spreadsheet as the canonical +list of BSP patches, and update the status as patches are merged in mainline. + + +Topic 3. BSP team requests +-------------------------- + +- Cache management on V4L2 + +The problem is well known but no mainline solution has been developed yet. +There is however interest in this topic from various companies. + +This can be handled as additional task(s), the schedule needs to be discussed. + +- Rotation and image partitioning + +Image partitioning has been implemented and merged in mainline for v4.9. +Rotation support has been implemented as well but currently blocked on review. +The upstream target is v4.10 at this point. + +- V4L2 Request API + +The API will be discussed tomorrow during a whole day V4L2 meeting with Hans +Verkuil and Sakari Ailus among others. More information about the upstreaming +schedule will be available then. + +- VSP1 state bug + +Two race conditions have been found recently. One of them has already been +fixed in mainline (v4.9): + +commit bfb4d5be9e1d5a70d0710e815d15a4245eaaafc4 +Author: Kieran Bingham <kieran+renesas@bingham.xyz> +Date: Tue Sep 6 14:07:09 2016 -0300 + + [media] v4l: vsp1: Repair race between frame end and qbuf handle + +Work is in progress on a second one. Whether the issue found by the BSP team +is identical isn't known yet. It would be helpful if the BSP could retest with +the above commit. We can schedule an additional task for this quarter to solve +the problem if it still occurs. + +- DU/VIN DT style difference between ES1.x and ES2.0 + +The DU and attached VSPs have changed significantly between ES1.x and ES2.0. +This will require different compatible strings. The "renesas,vsps" property +will still be used, referencing 3 VSPs instead of 4. There should be no other +change needed to the DU DT bindings. + +For VIN, differences between ES versions are limited to CSI2 routing. This is +hardcoded in the driver at the moment. As VIN has no IP core version register, +routing selection has to be done through different compatible strings at the +minimum. Another option would be to express full routing in DT, but that would +be more complex and isn't considered as a good solution. + +- Is it possible to have VIN on renesas-drivers in 11/M ? (M3/H3) + +VIN on Gen3 requires the external HDMI to CSI2 ADV7482 driver. At the moment +the existing driver is a prototype that hardcodes input selection due to +missing V4L2 APIs upstream (this topic will be discussed face to face with +Hans Verkuil this week). Whether the code can be merged in renesas-drivers +depends if the renesas-drivers tree is a Renesas -next staging area or a BSP +staging area. We expect the core group to discuss this topic and provide an +answer. + +- Is it possible to have M3 DU on renesas-drivers in 11/M ? + +Yes. + +- rcar-du + dma-buf + fence + +The DU driver supports buffer sharing with dma-buf, but doesn't implement +fence support. Support for the upstream API can be implemented, but can't be +tested at this time with the GPU due to the GPU driver not being publicly +available. We can thus schedule fence support as an additional task, but +without any guarantee that it will work out of the box with the SGX driver +stack. + +- horizontal lines appears in the plane + +The BSP team noticed a display corruption issue with renesas- +drivers-2016-09-20-v4.8-rc7 with the following patches applied: + + - gen3_du_ipmmu.config + - 0001-linux-v4.8-rc-fcp-get-device-20160901.patch + - 0002-arm64-dtsi-r8a7795-Enable-IPMMU-node-for-DU0-1-2-3.patch + - 0003-v4l-vsp1-Add-underrun-hung-up-workaround.patch + +If we can get those four patches we will investigate and provide a fix or, if +the problem is complex, a plan. + +- Runtime SRC (Sampling Rate Converter) connection on R-Car sound + +The customer would like to use the SRC several times in the audio pipeline. +This can't easily be handled with the current driver design. The exact use +case behind the request isn't known, Morimoto-san asked for details. If the +use case is valid, implementation would require major changes to the driver. + + +Topic 4.

I mean Gen3 +10:10 < geertu> horms: The current implementation (with SW23 and PMIC) doesn't really keep in mind how suspend works on Linux +10:10 < geertu> I've tried on H3, where we do have bias support, and GPIO wake-up doesn't work +10:11 < geertu> So the only wake-up source we have is SW23? +10:11 < horms> Did you also test on M3-W? +10:11 < khiemnguyen> yes, in suspended state, the board are powered down. +10:11 < geertu> M3-W doesn't have bias support yet +10:11 < khiemnguyen> only SW23 can signal to PMIC and trigger the resume. +10:11 < horms> My assumption is that the SW23 situation is a work around. +10:11 < geertu> khiemnguyen: What if the user wants a different wake-up source? +10:12 < horms> Can we confirm what the plans of the firmware team are in this regards? +10:12 < geertu> E.g. wake-on-LAN? +10:12 < khiemnguyen> geertu: we will need different board ;) +10:13 < geertu> Alternative, if extra wake-up sources are enabled, can we do it like on Gen2? +10:14 < geertu> I.e. keep the SoC powered, so it will receive and act on interrupts? +10:14 < khiemnguyen> for Gen3, it's target to not only SoC, but board power down. +10:15 < khiemnguyen> if SoC is power down only, like Core-Standby, L2 shutdown, we can use other wakeup sources, like interrupts. +10:16 < horms> I wonder how this aligns with customer expectations. +10:16 < geertu> khiemnguyen: It depends on the use case. Some users may want Wake-on-LAN or Wake-on-GPIO +10:18 < khiemnguyen> geertu: so, we can let them use SoC power down only. We can able to achieve it. +10:18 < horms> I think that would be more in keeping with how S2RAM works on Gen2. +10:19 < geertu> khiemnguyen: OK. +10:19 < horms> Which may also me aligned with users's expectations +10:19 < geertu> khiemnguyen: I was also considering future use cases (cfr. RZ/G) +10:19 < horms> But I assume that this would involve more power consumption. +10:20 < khiemnguyen> geertu: RZ/G is similar to Gen2. +10:20 < geertu> horms: One question is if we can do this in the kernel without touching arm64 core code, which may be hardwired to call into PSCI anyway +10:20 < horms> true +10:20 < khiemnguyen> geertu: for armv8, we need to use PSCI. +10:21 < geertu> khiemnguyen: I know.

[17:41] +<morimoto> is it HW issue ? or SW issue ? +<pinchartl> that's a good question +<pinchartl> I don't know at this point +<morimoto> OK, I will talk with BSP team about it. [17:42] +<pinchartl> thanks +<morimoto> and last question. do you have plan about suspend/resume bug fix ? +<morimoto> vsp1_pm_suspend() +<morimoto> Oops, it need normal suspend/resume base. maybe next year ? [17:43] +<horms> pinchartl: i have two questions if there is time at the end [17:44] +<pinchartl> Kieran will look at that for Q4/2 on Gen2. for Gen3 we neeed + additional suspend/resume core work, that will be for 2017/Q1 +<kbingham> pinchartl: You know I don't have any G2 hardware right :D [17:45] +<pinchartl> kbingham: good point :-) it can be emulated on Gen3 though, with a + small hack to make sure the FCP won't be suspended at the wrong + time [17:46] +<pinchartl> the point isn't so much to work on Gen2 but to fix the issues + internal to the VSP driver +<kbingham> Ok! +<pinchartl> the suspend/resume issues caused by the dependency on FCP are out + of scope at this time [17:47] +<pinchartl> horms: go ahead [17:48] +<horms> 1. How does Jacopo fit into things? Is he working with us these days? +<pinchartl> he's working on a trial task +<horms> ok, thanks. [17:49] +<pinchartl> his task is to write a buffer sharing application +<pinchartl> and we'll use it to measure performance issues and improvements + related to cache management +<horms> 2. I am wondering what the status of your upporting from BSP work + is. Mainly because as you know its reporting season and I'd like to be + sure I have any pending updates in my report. +<pinchartl> I have to send a report about that by 11/M [17:50] +<horms> ok, I got a patch from him last week. I wasn't aware he was on our + team. Its good to know. +<pinchartl> I'll submit the simple patches +<pinchartl> and will list areas that need more work +<pinchartl> based on the spreadsheet that you provided +<horms> superb, thanks +<horms> fwiw kaneko san will start analysing the 3.4.0.rc1 BSP [17:51] +<pinchartl> by the way, the spreadsheets hosted on google docs and attached in + the osdr wiki are different +<pinchartl> that's a bit confusing +<horms> which iirc was released last week +<horms> ok +<horms> i'll look into that +<horms> probably best to delete the copy in the wiki as the google one keeps + changing +<pinchartl> sounds good to me [17:52] +<morimoto> According to Renesas guys, you can buy ULCB board by AMAZON (Now + Gen2, Gen3 soon).

The issue is if you want it earlier ;-) +09:27 < horms> s/easy/easier/ +09:27 < horms> I am in no rush +09:27 < geertu> ok +09:27 < horms> sorry for giving the impression that I was +09:27 < geertu> Thanks Niklas +09:27 < geertu> Next is Morimoto-san +09:28 < morimoto> int a, b, c; +09:28 < morimoto> +09:28 < morimoto> a = b = c = -ENOTASK; +09:28 < morimoto> +09:28 < morimoto> return 0; +09:28 < morimoto> +09:28 < geertu> return -EPROBE_DEFER? +09:28 < morimoto> no idea :) +09:29 < geertu> morimoto: you found the hard drive? +09:29 < morimoto> But I need to know BSP team's question answer :) +09:29 < geertu> Sure, that's a separate topic. +09:29 < morimoto> hard drive ? +09:29 < geertu> "Our team's server HDD has gone" (HDD != hard disk drive?) +09:30 < morimoto> Ahh, yes ! +09:30 < morimoto> I re-start works for us :) +09:30 < geertu> Good. +09:30 < morimoto> Thanks +09:30 < geertu> morimoto: About TDSEL: Sure there must be documented HDL source code for R-Car Gen2? +09:31 < morimoto> Maybe, but I don't know +09:31 < pinchartl> geertu: s/documented // +09:31 < morimoto> HW team is busy +09:32 < geertu> OK +09:32 < pinchartl> morimoto: if we can get the HDL source we can have a look and find out :-) +09:32 < geertu> Can I include it in renesas-drivers? +09:32 < morimoto> 1) Maybe HW team doesn't give it to me +09:32 < morimoto> 2) It can't export to you guys +09:33 < morimoto> I can't export +09:33 < horms> morimoto: i think they were joking :) +09:33 < morimoto> :( +09:33 * geertu was +09:33 < geertu> THanks, Morimoto-san +09:33 < morimoto> geertu: what is "it" mean ? +09:33 < geertu> Next is Magnus +09:34 < geertu> it == HDL source +09:34 < geertu> -EJAPANESE_LESSON? +09:34 < morimoto> Ahh, of course not +09:34 < geertu> Next is Laurent +09:34 < morimoto> -EDRINKING +09:35 < pinchartl> nothing to report +09:36 < geertu> Thanks Laurent +09:36 < geertu> Next is Khiem +09:36 < geertu> -EINTR? +09:37 < geertu> Next (last) is Geert +09:37 < geertu> A) What have I done since last time - Completed SoC identifaction - Queued up RZ/G1M and RZ/G1E clock drivers, - Sent more clock and pinctrl pull requests, +09:37 < geertu> B) What I plan to do till next time - Coerce Simon into taking all MODEMR related patches, - Investigate IPMMU and Ethernet +09:37 < geertu> C) Problems I have currently - What's wrong with the IPMMU and Ethernet? +09:37 < geertu> (hm, bad formatting. should switch to .rst?) +09:38 < geertu> Anyone else who tried IPMMU and had mixed results? +09:38 < horms> For B, we need to to take into account our recent interation with Mr. Olof. Probably after the current round of bother blows over. +09:38 < pinchartl> geertu: there's "a bit" of corruption on the screen when IPMMU is enabled for the VSP/DU +09:39 < geertu> B depends on the RST series, which is going in through clk +09:39 < shimoda> pinchartl: about VSP/DU with IPMMU, did you try on M3? +09:40 < geertu> pinchartl: Corruption could explain it. I haven't dug deeper into it, but NFS root works initially, then the network stops working (on M3) +09:40 < pinchartl> shimoda: not personally, no +09:41 < neg> I have problem on H3 and VIN+IPMMU, corruption on VIN1 but not on VIN0 if I look at the video using applications but works fine in VIN->DU +09:42 < shimoda> pinchartl: i see. H3 ES1.x has an issue about ipmmu. if multiple request happens from hw, the IPMMU TLBs will currupt +09:43 < pinchartl> shimoda: that could explain it +09:43 < pinchartl> we should retest everything on M3 +09:43 < shimoda> pinchartl: I think so +09:43 < geertu> Any known issues on M3? +09:45 < shimoda> geertu: about IPMMU? if so, no serious issue on M3, but some performance issues exist +09:46 < geertu> OK +09:46 < geertu> Let' +09:46 < geertu> s continue +09:46 < geertu> Topic 2. CPG/MSSR reset support +09:46 < geertu> From morimoto-san +09:46 < geertu> We would like to have MSTP::Reset feature for each devices, +09:46 < geertu> it is requested on HW user manual (maybe we don't have it ?). +09:46 < geertu> This Reset is necessary on initial time. +09:46 < geertu> First of all, who should handle it ? by Linux ? by IPL ? +09:46 < geertu> If answer was "IPL", we will ask it to BSP guys. +09:46 < geertu> If answer was linux, it can be Core topics. +09:46 < geertu> I guess it should be handled by pm_runtime_xxx() ? +09:46 < geertu> EOT +09:47 < geertu> To me, it looks like this should be handled by the CPG/MSSR driver (the old MSTP driver cannot easily be extended for that) +09:48 < pinchartl> I agree. there's a reset controller API in the kernel that can be used for this purpose +09:48 < geertu> I'm a bit puzzled by the conflicting "This Reset is necessary on initial time." and "I guess it should be handled by pm_runtime_xxx()" +09:48 < morimoto> please drop last comment +09:48 < geertu> It's still a bit unclear how this is supposed to be used. +09:48 < morimoto> it is just my opinion +09:48 < geertu> OK +09:49 < geertu> From a quick look, drivers call into the reset controller API when they want to reset a module? +09:49 < geertu> But that means the driver for the module is in control, why we need reset for all modules on initial time? +09:49 < geertu> Also, what does the "HW user manual" say? +09:50 < pinchartl> could "initial time" mean "probe time" ? +09:51 < geertu> Possibly. +09:52 < geertu> Or "resume" time? (with "DDR backup" in the BSP) +09:52 < morimoto> Above my comment (= pm_runtime_xxx) was based on every "use time" +09:52 < geertu> If this is a common requirement, it would be good to handle it in common infrastructure, and not in each individual driver (cfr. PM domains) +09:53 < geertu> morimoto: Note that each time you reset the module, all registers are changed to their reset values +09:54 < morimoto> Yes, I know. Each driver shouldn't assume it can keep register settings IMO +09:56 < geertu> If you reset the module on every pm_runtime_get_sync(), you have to restore all registers all the time, which will kill performance +09:57 < morimoto> But it is necessary if you want to support Suspend/Resume. +09:57 < morimoto> Suspend will kill Power, and all register value will gone +09:57 < geertu> If "reset on initial time" is the only thing we need, then the CPG/MSSR driver could reset each module the first time its clock is enabled. +09:58 < geertu> morimoto: Sure, but that doesn't mean we have to do it in every pm_runtime_get_sync(), only when resuming. +09:58 < morimoto> Current R-Car doesn't have PowerDomain, so maybe yes. But if SoC has PowerDomain, it needs +09:59 < geertu> If Suspend kills power, we have to reset the module after resume, too? +09:59 < morimoto> If SoC has PowerDomain, and if no user exist, module power will be killed +10:01 < pinchartl> Gen3 has power domains +10:01 < geertu> Yes, and we already have to handle that in drivers shared with SH/R-Mobile, which does have power domaains +10:02 < geertu> Still, it would be good to know what the "HW user manual" says... Is that document available? +10:02 < morimoto> About Reset, maybe it is needed on Probe time, and resume time. +10:02 < morimoto> My pm_runtime_xxx is related a little bit different topic +10:02 < pinchartl> one concern I have with resetting modules is that the secure firmware might poke with some (possibly undocumented) registers after resume. if we then reset the modules, things might start breaking +10:03 < geertu> Can't the secure firmware prevent us from resetting some modules? +10:05 < pinchartl> indeed it can +10:06 < geertu> I think we need to know more of the "why" behind this request. We've been living without resetting modules for many years. +10:07 < pinchartl> for some modules, though, it would be useful, if only as a workaround +10:07 < pinchartl> for instance the VSP sometimes fail to stop +10:07 < pinchartl> that's most likely cause by a driver bug +10:07 < geertu> OK. That reset under driver control. +10:07 < geertu> Not "This Reset is necessary on initial time" +10:07 < pinchartl> but the failure can be detected, and a module reset could potentially be helpful +10:07 < geertu> s/That/That's/ +10:08 < pinchartl> correct, although I wouldn't mind being able to reset moduls at probe time, to wipe off crazy configurations applied by the boot loader :-) +10:08 < pinchartl> that problem should of course ideally be fixed in the boot loader, which shouldn't apply crazy configurations in the first place +10:08 < geertu> Well, drivers should not make assumptions about the boot loader, and initialize all registers anyway? +10:10 < morimoto> geertu: not all, but some deivce was indicated on datasheet. +10:10 < pinchartl> it's easily to overlook a register whose reset default value is fine +10:10 < morimoto> For example SATA, can you see v0.52 manual, 72.3.10 ? +10:12 < pinchartl> morimoto: I think that what we'd like to know is whether some modules require a reset (as in the module will fail in more or less subtle ways if it's not reset) or if it's more of a good practice rule that would make the BSP team sleep better at night +10:13 < pinchartl> or, to put it differently, what are the problems that will be fixed by resetting modules ? +10:14 < geertu> Exactly. +10:14 < morimoto> SATA, Thermal are indicated on datasheet, Sound was indicated on Application manual +10:14 < geertu> The flow chart in 72.3.10 is indeed interesting +10:14 < morimoto> The reason why BSP team needs it is because it is indicated on datasheet :( +10:15 < geertu> 1. It refers to SASRSTECR (unfortunately in graphical form, so a text search won't find it) +10:15 < geertu> 2. The corresponding CPG/MSSR sections says: This register is functional safety use only. Keep initial value +10:15 < geertu> ??? +10:16 < horms> morimoto: I understand that the BSP team wants to comply with the documentation. But in my experience some kind of run-time behaviour enhancment/fix/... helps to motivate changes in mainline +10:18 < morimoto> horms: do you mean, "because it was indicated on datasheet" is not good reason ? +10:18 < horms> i mean it would be easier from a mainline point of view if that was not the only reason +10:21 < geertu> I think we should move on to the next topic... +10:21 < geertu> Topic 3. R-Car DMAC transfer termination synchronization support +10:21 < geertu> From Morimoto-san: +10:22 < geertu> BSP team has rcar-dmac issue. Laurent posted its patch last year, but it was +10:22 < geertu> canceled. because it needed new frame-work. +10:22 < geertu> https://patchwork.kernel.org/patch/7175381/ +10:22 < geertu> Now, upstream has it. It can be next Core group Task ? +10:22 < geertu> b36f09c3c441a6e59eab9315032e7d546571de3f +10:22 < geertu> ("dmaengine: Add transfer termination synchronization support") +10:22 < geertu> EOT +10:22 < geertu> Is there anything to discuss, or just a task to add? +10:22 < morimoto> pinchartl: can you explain ? +10:23 < pinchartl> the BSP patch was waiting for the hardware to complete all transactions when terminating them +10:24 < pinchartl> but the termination function was sometimes called from non-sleepable contexts, so I nacked the patch +10:24 < pinchartl> now the DMA engine API has support for synchronous and asynchronous termination +10:24 < pinchartl> so we can implement the feature +10:25 < morimoto> it can be 17Q1 task ? +10:26 < geertu> I think so +10:27 < morimoto> Nice. BSP team (or customer) needs it +10:27 < geertu> Topic 4. Shared GPIOs +10:27 < geertu> From Laurent: For key + LED operation +10:27 < pinchartl> Linus isn't against the idea +10:28 < pinchartl> all we need is someone to implement it +10:28 < pinchartl> neg: did you say you were looking for a core task ? :-) +10:28 < geertu> I think he already has an option on "GPIO-RCAR,?,noplan,?,Fix Runtime PM with GPIO interrupts (depends on irqchip PM) +10:29 < pinchartl> shared GPIOs might not be the most urgent one though, but it's nice for our upstream PR to drive API and framework changes +10:29 < geertu> Well said ;-) +10:30 < geertu> I'll add a task to core/todo +10:30 < geertu> Topic 5. BSP GPIO question +10:30 < horms> fwiw, i am for such activities +10:30 < geertu> shimoda: Any last minute info? +10:30 < neg> I happy to work on either of them :-) +10:32 < shimoda> unfotunately, i don't receive the detail so we can skip it :) +10:32 < shimoda> i'll forward it by email laster +10:32 < geertu> OK, thanks +10:32 < shimoda> s/laster/later/ +10:32 < geertu> Anything else to add? +10:34 < neg> Have we settled on next face to face core meeting to be at FOSDEM timing? +10:34 < geertu> Well, looks like Magnus wants to evade by arriving late? ;-) +10:35 < geertu> Probably it'll happen on Friday (half a day shared with I/O) +10:35 < horms> geertu: any thoughts on Olof's idea regarding pfc/Kconfig? +10:36 < geertu> horms: I still have to reply why it's a bad idea +10:36 < horms> ok +10:36 < horms> fwiw, i think its a can of worms +10:37 < pinchartl> geertu: Friday before the FOSDEM ? +10:37 < geertu> pinchartl: yep +10:37 < pinchartl> I'll be there +10:37 < geertu> OK +10:37 < geertu> Thanks for joining, and have a nice continued day! +10:38 < pinchartl> I mean, at least in Belgium :-) +10:38 < neg> I only asked so i can buy tickets before my financial year ends :-) I will be there +10:38 < geertu> horms: Bummer, forgot to email sfr yesterday +10:38 < horms> I also expect to be there +10:39 < horms> geertu: I for one was distracted +10:57 < morimoto> I guess chat meeting was finished ? +10:57 < horms> I guess so too +10:59 < neg> next meeting in 2 weeks, same time? +10:59 < geertu> Yes, that's the plan. Will send the report later +10:59 < morimoto> Today is started on EuroPeri side, but Today will finish on Japan side. So, please finalize meeting if it was finished.

Sorry - I thought geertu was asking as I had been talking with him about JTAG :D +09:16 < kbingham> pinchartl: No - I believe HDMI worked once I managed to get the patches applied correctly. +09:16 < pinchartl> ok, thank you +09:16 < pinchartl> next in alphabetical order, more +09:17 < pinchartl> since last meeting, I've followed up on the LVDS mode selection patches and posted a new version of the patch series +09:17 < pinchartl> or the two patch series I should say, covering both LVDS panel and LVDS encoder +09:18 < pinchartl> the feedback I got from Rob on the DT bindings was much more positive +09:18 < pinchartl> but Thierry Redding now chimed in and wasn't thrilled, to say the least +09:18 < pinchartl> we have very different opinions +09:19 < pinchartl> more work is needed to fix some issues +09:19 < pinchartl> and to either convince Thierry, or exhaust him until he stops caring +09:20 < pinchartl> a v3 is under preparation +09:20 < pinchartl> the LVDS encoder support series makes the DU driver cleaner by removing manual handling of bridges +09:21 < pinchartl> so I plan to make it a base for HDMI output upstreaming on Gen3 +09:22 < pinchartl> I've also posted a few misc DU patches forward-ported from the BSP +09:22 < pinchartl> and they have been merged by Dave +09:22 < pinchartl> along with a bunch of other pending DU patches +09:23 < pinchartl> I've finished classifying the BSP patches +09:24 < pinchartl> I need to follow-up with the BSP team as it wasn't clear for some of them if they fixed real issues +09:24 < pinchartl> a few tasks have also been identified +09:24 < pinchartl> they will be candidate for additional tasks +09:25 < pinchartl> for the next two weeks +09:25 < horms> feel free to let me know if you want me to help contact the BSP team +09:25 < pinchartl> I still plan to post a proposal for the rotation and histogram API (haven't had time to address it yet) +09:25 < pinchartl> horms: thanks +09:26 < pinchartl> my plan is to ask Matsuoka-san, CC'ing the periperi mailing list +09:27 < horms> ok, that sounds like a good plan +09:27 < pinchartl> I will also start discussing V4L2 cache handling with upstream developer +09:28 < pinchartl> and upstream basic support for HDMI output on Gen3 +09:29 < pinchartl> and, as I've already mentioned, still work on LVS panel and encoder support +09:29 < pinchartl> my main issues right now are Mauro doing his bad maintainer play again +09:30 < pinchartl> and Thierry not liking the LVDS panel DT bindings (and driver) +09:30 < pinchartl> that's it for me +09:30 * kbingham gets the popcorn to watch #v4l +09:31 < pinchartl> kbingham: it was quite surreal yesterday +09:31 < pinchartl> you need to know quite a bit about the technical problems being discussed to follow +09:31 < pinchartl> but I really felt I was in a parallel universe where the known rules of software architecture didn't apply +09:32 < kbingham> :) +09:32 < pinchartl> by the way the three new tasks I've identified from the BSP are +09:32 < pinchartl> - DU suspend/resume +09:33 < pinchartl> - Gen3 DU dot clock rate optimization (with DPLL) +09:33 < pinchartl> - Display interlace support +09:33 < pinchartl> the second one is part of Ulrich's HDMI output patches +09:33 < pinchartl> I might get it done as part of the HDMI output upstreaming, but might also leave it out +09:33 < pinchartl> depending on how much time it takes +09:33 < horms> Thanks, I'll try to add that to the google sheet if you haven't done so already +09:34 < pinchartl> do we have tasks in that spreadsheet ? +09:35 < horms> not as such. +09:35 < pinchartl> ok :-) +09:35 < horms> but we have "Features" +09:36 < pinchartl> I've added them to the multimedia todo list (will push after this meeting) +09:36 < horms> And I think it makes sense to map the Features to tasks where possible +09:36 < pinchartl> I'm done +09:36 < pinchartl> neg: you're next +09:36 < neg> a) Nothing +09:36 < neg> b) Address CSI2 review comments +09:36 < neg> c) None +09:36 < neg> EOT +09:38 < pinchartl> I assume you're busy with I/O and/or core tasks at the moment ? +09:39 < neg> Not super busy, trying to start a new core task and finish up my IO task so if yout got something that needs to be done I might have time +09:39 < pinchartl> I'm looking at the todo list +09:40 < pinchartl> we have a bunch of tasks planned for v4.10 that need to be pushed back +09:40 < pinchartl> for you that's +09:40 < pinchartl> ADV7482,v4.10,plan,niklas,Gen3 support upstream +09:40 < pinchartl> ADV7482,v4.10,plan,niklas,Interlace support upstream +09:40 < pinchartl> VIN,v4.10,public,niklas,Gen3 support +09:40 < pinchartl> VIN,v4.10,plan,niklas,Scaler support (on Gen3) +09:40 < pinchartl> VIN,v4.10,public,niklas,CSI2 interlace support upstream (Gen3) +09:40 < pinchartl> VIN,v4.10,public,niklas,CSI2 support upstream (Gen3) +09:40 < pinchartl> VIN,v4.10,plan,niklas,Gen3 support upstream (without CSI-2) +09:40 < pinchartl> should I push them back to v4.11 or directly to v4.12 ? +09:41 < neg> I don't think we can move forward with CSI2 without VIN and so far there have not been much review on the series which is huge so I assume it will miss v4.11, or how do you feel about it? +09:42 < pinchartl> I agree with you +09:42 < pinchartl> unless we decide it's a high priority and put lots of effort on that +09:42 < pinchartl> but that doesn't seem to be the case at the moment +09:42 < pinchartl> so v4.12 seems more realistic to me +09:43 < neg> for ADV7482 I have mixed feelings about having it in periperillist, is that something we still feel is a task to bring to upstrem since there are a huge effort to do so? +09:43 < pinchartl> I don't think so at the moment. I'll mark it as noplan +09:43 < pinchartl> but keep it there as it would be nice to have +09:45 < neg> yes I would love to get it upstream one day, I will keep to work on the driver so I can test VIN but the big push to make it ready for upstream I feel is a low prio thing +09:45 < pinchartl> thanks +09:45 < pinchartl> next, uli___ +09:45 < uli___> as mentioned above, i have pushed out a base for upstreaming hdmi out on gen3 +09:46 < uli___> and a tool for testing analog audio remotely with a loopback cable +09:46 < uli___> https://github.com/uli/atest +09:46 < uli___> for interested parties +09:46 < uli___> mixer settings are tricky, but the readme contains a few hints +09:46 < kbingham> uli___: I like atest - that's neat :D +09:46 < uli___> thank you :) +09:47 < uli___> next, i will upport/test/fix ipmmu patches for du, vsp and fcp +09:47 < uli___> haven't looked into that yet +09:47 < uli___> no issues +09:47 < uli___> that's it from me +09:48 < pinchartl> what's the status of VIN,v4.10,public,ulrich,Gen2 VIN integration ? have the patches been merged ? +09:48 < uli___> i'm not sure, actually +09:48 < pinchartl> horms might know ? +09:49 < uli___> or neg +09:49 < pinchartl> those are DT patches +09:49 < horms> I don't believe so +09:49 < horms> I can look up but most likely I was expecting some Acks and then it fell off my radar +09:50 < pinchartl> I see the following patches in your tree +09:50 < pinchartl> 06b64afa6e98 ARM: dts: r8a7793: Enable VIN0-VIN2 +09:50 < pinchartl> 84e3a74664c5 ARM: dts: koelsch: add HDMI input +09:50 < pinchartl> 56548d0c5aea ARM: dts: lager: Add entries for VIN HDMI input support +09:50 < pinchartl> uli___: were there more ? +09:50 < uli___> for gose, i think there was an issue +09:50 < uli___> it's missing the enablement for analog and hdmi in the dts file +09:51 < uli___> i'll look into that +09:51 < pinchartl> thanks +09:51 < horms> yes, i think those things are missing from gose +09:51 < horms> i'm entirely usnure why +09:51 < pinchartl> I'll update the target to v4.11 then +09:52 < horms> please feel free to ping me any time if dt patches seem stuck +09:53 < pinchartl> "[PATCH v2 2/3] ARM: dts: gose: add HDMI input" is ready to be merged with a small fix that I requested +09:53 < pinchartl> "[PATCH v2 3/3] ARM: dts: gose: add composite video input" will require a bit more work +09:54 < uli___> yes, i think i'll resend the hdmi part individually, so it won't me tainted by disparaging comments :) +09:54 < uli___> s/me/be/ +09:55 < pinchartl> you can also start to update the ADV7180 DT bindings already +09:55 < pinchartl> the only open item is what compatible strings to use +09:55 < pinchartl> the rest can already be fixed +09:56 < uli___> i'll have a look +09:57 < pinchartl> thanks +09:58 < pinchartl> next meeting +09:58 < pinchartl> I propose 2016-12-07 at the same time as today +09:58 < pinchartl> 08:00 GMT / 09:00 CET / 10:00 EET / 17:00 JST +09:58 < neg> uli___: thanks for all your work for VIN, I'm looking forward to v4.10 and out of the box HDMI VIN for gen2 :-) +09:59 < neg> Meeting time works for me +09:59 < uli___> you are welcome :) +09:59 < kbingham> uli___: Then you can write a vtest to do a video loopback with embedded data verification too :D +10:00 < horms> FWIIW that is not a holiday in Japan +10:00 < uli___> kbingham: don't give anybody ideas +10:00 < pinchartl> horms: I'm sure they'll find another excuse ;-) +10:00 < pinchartl> (it's the day after the Finnish independence day) +10:00 < horms> no comment +10:00 < neg> vtest +1 :D +10:00 < pinchartl> does anyone have anything to add ? +10:00 < kbingham> uli___: Should be possible to do straight byte comparisons - but encoding the bytes sounds more fun :D +10:00 < horms> Indepemdence from Sweeden_ +10:00 < horms> _ +10:00 < horms> ? +10:01 < pinchartl> from Russia I believe +10:01 < horms> Ok.

BSP team would like to set the such pins via PFC driver +09:29 < shimoda> the pins spec differs than other pins. so bsp team think that the PFC driver should have other way +09:29 < geertu> IIUIC, multiple functions can be muxed to the i2c pins, but they cannot be used for GPIO? +09:30 < shimoda> geertu: let me check... +09:30 < geertu> It uses PIN_NUMBER('B', 11) +09:32 < geertu> But it also touches avb, hscif, msiof, pwm, sdhi +09:33 < geertu> Does it mean those functions are mutually exclusive with the i2c function, although they use different pins? +09:33 < geertu> And is this ES1.0 or ES2.0? +09:35 < shimoda> geertu: i don't know this is ro es1.0 or es2.0 +09:37 < shimoda> about this mod_sel, as you said, they are muxed pins. +09:39 < shimoda> and these i2c pins cannot bd used for GPIO +09:40 < shimoda> this patch reuses POC/DRVCTRL register setting thing +09:41 < shimoda> BSP team would like to know this policy is good or not +09:41 < geertu> Ah, it's for e.g. "Phisically muxed with AVB_AVTP_MATCH_A" inside some floating comment box in (preliminary)CSD15-676_R-CarH3_pinfunction(Rev0p290)_customer.xlsx, which you cannot search for using LibreOffice +09:44 < geertu> According to that xlsx, it uses the same pin numbers as the "Phisically muxed" pins, but in a different row of the sheet. +09:45 < neg> It's pinmux for none-GPIO pins right? +09:45 < geertu> Can't we just use the corresponding RCAR_GP_PIN()? +09:46 < geertu> E.g. SCL0 is SoC pin AA33, SiP pin C29 +09:47 < geertu> But SD1_CD is also AA33 / C29, and GP3_14 +09:48 < geertu> so we could use RCAR_GP_PIN(3, 14) instead of PIN_NUMBER('C', 29)? +09:48 < geertu> What am I missing? +09:49 < geertu> I think this needs more clarificiation / investigation, offline. +09:50 < geertu> shimoda-san: Do you agree? +09:51 < shimoda> geertu: about red line in the xlsx file, it seems your comment is match, i will ask hw team or/and bsp team +09:51 < shimoda> and offline, it's nice to me :) +09:51 < shimoda> s/red line/red rectangles/ +09:52 < neg> yes, I think if there are a RCAR_GP_PIN() for that pin it should be used, or I'm also missing something +09:52 < geertu> It depends on what "Phisically muxed" really means +09:54 < geertu> (in gnumeric, it shows a black rectangle. I also cannot search for its contents, but I can move (not edit) it ;-) +09:54 < geertu> Let's continue +09:54 < geertu> Topic 3.

He don't like + current style. Now I'm discussing about it. +<morimoto> +<morimoto> B) +<morimoto> DU side DT will have HDMI video and sound. ALSA SoC side needs to + know total how many HDMI sound port exist. +<morimoto> but, Rob rejected "type=" property. So, I can't know. +<morimoto> ---- from Rob ---------------- +<morimoto> I still don't think this is necessary. Simply define which port + number +<morimoto> is which for each HDMI chip. +<morimoto> If this is necessary, then the types, video and sound, are too + generic. +<morimoto> ------------------------------ +<morimoto> What does it mean ?? How to get this information from ALSA side ?? +<morimoto> I think I need to corroborate with HDMI video ? +<morimoto> s/corroborate/collaborate [17:19] +<morimoto> C) [17:20] +<morimoto> I need to re-create OF-graph patches. +<morimoto> Can I use Laurent version ? I'm using Ulrich version +<morimoto> -- EOT -- +<pinchartl> regarding the type property +<pinchartl> the DT bindings for each HDMI encoder define the number and type + of each port +<pinchartl> Rob's point is that, instead of adding a generic type property, + you should query the HDMI encoder driver at runtime to know the + number of audio ports [17:21] +<pinchartl> I'm not sure if that's feasible though, I haven't checked how it + works on ALSA"s side +<morimoto> but in runtime query, how the driver know total size ? [17:22] +<morimoto> fixed size, does it mean ? +<pinchartl> the driver knows because the driver knows the hardware +<pinchartl> it's hardcoded in the driver [17:23] +<morimoto> OK, I see. +<pinchartl> for instance let's say we have an HDMI encoder with two sound + inputs, one video input and one HDMI output +<pinchartl> that's 4 ports +<pinchartl> the DT bindings would document something like +<pinchartl> port 0: video in +<pinchartl> port 1: audio 0 in +<pinchartl> port 2: audio 1 in +<pinchartl> port 3: hdmi output [17:24] +<pinchartl> then let's imagine that the board has audio 1 in connected +<pinchartl> and audio 0 not connected +<pinchartl> DT would have port 2 connected with an endpoint +<pinchartl> and port 1 not connected, with no endpoint +<pinchartl> the driver would parse the DT node +<pinchartl> see that port 1 is not connected and port 2 is connected [17:25] +<pinchartl> and conclude that there's one audio input in use among the two + possible audio inputs +<pinchartl> there's no need for a type property there +<pinchartl> the type property would only be needed if you need geenric code to + parse the DT node, code that has no knowledge of the device + [17:26] +<morimoto> So this mean we need new "query" function for it ? +<morimoto> it tell "for video port" "for sound port" or "connected", something + like that [17:27] +<pinchartl> that would be the idea. again, as I'm not too familiar with ALSA's + internals I don't know if that would be easy, or even good +<pinchartl> but Rob's point is that code that parses the OF graph in a + completely generic way is usually a bad idea [17:28] +<morimoto> OK +<pinchartl> because DT properties are defined by DT bindings in relationship + with the compatible strings +<pinchartl> so a generic function that walks through the OF graph, from node + to node, trying to collect information about each node, can't know + for sure what a property means [17:29] +<morimoto> +1 question is that this mean, DU driver will have this "query" + function, righ ? +<pinchartl> I'm not as opposed to that as he is, but I understand his point +<pinchartl> do you mean the dw-hdmi driver ? +<morimoto> I don't know. DU has port, right ? [17:30] +<morimoto> not dw-hdmi +*** horms (~horms@217.111.208.18) has joined channel #periperi +<pinchartl> the DU has a DT node, yes +<pinchartl> but DU doesn't handle sound +<pinchartl> the HDMI encoder DT node does [17:31] +<morimoto> Yes, yes.

So video side need to care it, + right ? [17:36] +<morimoto> (avoid sound port, etc..) +<pinchartl> yes it will +<morimoto> Or HDMI video/sound can share same port ? [17:37] +<pinchartl> it should be two different ports +<morimoto> OK, nice to know +<morimoto> I will investigate it next week. thanks +<pinchartl> so we would need an API to walk the DT graph with assistance from + drivers +<pinchartl> you're welcome +<morimoto> I will ask about query to Rob [17:38] +<pinchartl> I think I've answered your question about which version of the + HDMI patches you should use +<pinchartl> so now it's my turn :-) +<pinchartl> since last meeting [17:39] +<pinchartl> as I said, I've posted the HDMI output on Gen3 patches +<pinchartl> Kieran and I have been working together on that +<pinchartl> we got rid of all hacks [17:40] +<pinchartl> one of the good news is that ES1.x / ES2.0 don't need special + handling anymore +<morimoto> Nice +<pinchartl> the series cleans up and enhances the dw-hdmi driver +<pinchartl> I've received a few comments about that +<pinchartl> and reworked the patches accordingly [17:41] +<pinchartl> based on information I managed to gather about the Synopsys DWC + HDMI TX IP core +<pinchartl> it's not easy, as there's no public datasheet from Synopsys +<pinchartl> speaking of which, I talked to one of their engineers in private +<pinchartl> he said he wasn't allowed to give me information +<pinchartl> but that, if I needed support, I should be able to get it through + Renesas [17:42] +<pinchartl> he said that if Renesas contacted Synopsys' support, the question + would be routed to him, and he could then talk to me in direct :-) +<pinchartl> so far I managed to solve most of the problems withotu needing + that +<pinchartl> I've also done review, there was quite a bit of discussion about + the DRIF DT bindings [17:44] +<pinchartl> no time to post a proposal for the rotation and histogram APIs yet + I'm afraid [17:45] +<pinchartl> I'll try to address that in the next two weeks +<pinchartl> aV4L2 cache +<pinchartl> oops +<pinchartl> as well as starting the V4L2 cache discussion +<pinchartl> no real issue or blocker, I've been slowed down by the lack of + public dwc hdmi documentation, but I found a leaked datasheet and + gathered more information from several developers [17:46] +<pinchartl> so at the moment it's not an issue +<pinchartl> that's it for me [17:47] +<pinchartl> kbingham: your turn now +<kbingham> Ok :D +<kbingham> So - as per the mail I sent - I've fixed suspend resume on m2m + pipelines, and incorporated the fix for the BRU race I discovered + into this as well. [17:48] +<kbingham> I've also written a couple of automated tests for suspend resume + which should make their way into vsp-tests. - It's quite neat, as + it uses a PM debug tool in the kernel to suspend, and then + automatically resume after 5 seconds. [17:49] +<pinchartl> (bit of context for the reader, M2M pipeline refers to the VSP) + [17:50] +<kbingham> Ah yes - sorry - I was lacking context there :D - There are still + issues in the display pipeline but that is more complicated as we + are then dealing with making sure multiple cells suspend resume + cleanly I believe. [17:51] +<pinchartl> yes, DU suspend/resume still needs work +<kbingham> Aside from that - I've done some work on HDMI with Laurent, and + I've been supporting Duc@Jinso to help him get a set up for testing + the writeback prototype I posted last month. +<kbingham> My B) section is a little 'fuzzy' at the moment, so I'll leave that + section blank for now :D [17:52] +<kbingham> C) - There was a lot of time spent looking after Jinso :( [17:53] +<kbingham> D) Show(off) and tell - +<kbingham> - I've made an LED Christmas Tree Hat (for Xmas parties) +<kbingham> - https://goo.gl/photos/PRyXXbpJdJbokBQ56 +<pinchartl> :-D +<neg> nice +<kbingham> Speak of the devil - Duc@Jinso has just mailed me again :D [17:54] +<pinchartl> Morimoto-san: I've sent you an e-mail regarding the support we + have to provide to Jinso +<morimoto> Nice hat !

I don't think we can use it as-is. +09:19 < geertu> There doesn't seem to be a PIN_CONFIG_* for capacitance in enum pin_config_param yet. +09:19 <@wsa_> well +09:19 <@wsa_> the docs don't really allow configuration +09:19 < geertu> (about the hardcoded values) Or don't we need explicit configuration, and should we also use the same value? +09:20 <@wsa_> yes +09:20 < geertu> The docs are conflicting. +09:20 <@wsa_> for H2, they say bits "should be 01" +09:20 <@wsa_> which is not the reset value +09:21 <@wsa_> it even says "must be 01" +09:21 < geertu> Isn't there another doc that says "must be 00"? +09:21 < geertu> While the HW engineers responded that it's the same hardware block everywhere. +09:23 <@wsa_> Yes, M2-W says "must be 00" +09:23 < geertu> If we don't need configuration, doing it in .init() is fine for me. +09:24 <@wsa_> That's a good item for the FOSDEM meeting: +09:25 <@wsa_> if somebody could bring a koelsch, then we could check if the same SDR104 problem with TDSEL=00 exists +09:25 <@wsa_> or any other Gen2 board +09:26 <@wsa_> okay, that was all the topics I had +09:26 <@wsa_> anything left from your side? +09:27 < neg> I have question is this BUG http://pastebin.com/wycYBEyF which can be triggerd on Koelsch by 'reboot' using shmobile_defconfig + CONFIG_DEBUG_ATOMIC_SLEEP known? +09:27 < geertu> Is this card SDR-104? http://www.conrad.be/ce/nl/product/1388580/SanDisk-Ultra-SDHC-kaart-32-GB-Class-10-UHS-I +09:27 < geertu> "systemd-shutdow Not tainted"? Shouldn't systemd taint the system? ;-) +09:28 < geertu> I recently enabled CONFIG_DEBUG_ATOMIC_SLEEP in my .config, but haven't seen that message on my Koelsch. Usually not using shmobile_defconfig, though. +09:28 < neg> I need to switch to init for my NFS, can't boot properly without CONFIG_CGROUPS and CONFIG_SECCOMP :-) +09:29 < neg> the BUG is triggerd by running reboot and hits all the time for me +09:30 <@wsa_> geertu: it should be. it has uhs-1 and i've never seen cards which only support SDR50 but not SDR104 +09:30 <@wsa_> geertu: but shouldn't you play safe and go for micro-sd? +09:30 <@wsa_> I don't know about other Gen2 boards, but Lager has micro-sd only +09:30 < geertu> wsa_: OK. I used my Koelsch a few weeks ago to copy music to that card, to be used in my car. +09:31 <@wsa_> ah, you already have it +09:31 < geertu> Yes. +09:31 <@wsa_> well, the kernel log will tell you which mode was used +09:32 < geertu> I also have a similar smaller uSD card http://www.conrad.be/ce/nl/product/1381015/SanDisk-Ultra-16-GB-microSDHC-kaart-Class-10-UHS-I-incl-SD-adapter +09:32 < geertu> Also used koelsch to init that one ;-) +09:32 <@wsa_> and if the problem is the same, then you will get timeouts after a second or so after removing the card +09:32 < geertu> In SDHI0, of course (SDHI1 is slower) +09:33 <@wsa_> cool +09:33 <@wsa_> because it is only the san-disk card which causes the problem for me +09:33 < geertu> Lemme look in kern.log +09:33 <@wsa_> the samsung card works fine +09:33 <@wsa_> (mine is 64gb, though) +09:36 < geertu> mmc0: new ultra high speed SDR104 SDHC card at address 0007 +09:37 < geertu> mmcblk0: mmc0:0007 SL32G 29.0 GiB +09:37 < geertu> and in SDHI1: +09:37 < geertu> mmc1: new ultra high speed SDR50 SDHC card at address 0007 +09:37 < geertu> mmcblk1: mmc1:0007 SL32G 29.0 GiB +09:37 < geertu> The other one: +09:37 < geertu> mmc0: new ultra high speed SDR104 SDHC card at address aaaa +09:37 < geertu> mmcblk0: mmc0:aaaa SL16G 14.8 GiB +09:38 < geertu> According to the log, I removed and reinserted the second one, and that worked +09:38 <@wsa_> nice to know +09:38 < geertu> If there's anything else I can test +09:39 <@wsa_> don't think so +09:39 <@wsa_> re-inserting is the test to do +09:39 < geertu> You need my TDSEL values? +09:40 <@wsa_> ah, yes +09:40 <@wsa_> i assumed they were 0, but there is firmware involved +09:43 < geertu> => md.l 0xe6060084 2 +09:43 < geertu> e6060084: 00000000 00000000 ........ +09:46 <@wsa_> ok +09:46 <@wsa_> thanks! +09:46 <@wsa_> i'll bring my "magic card" to Brussels nonetheless :) +09:46 < geertu> If you need anything else to be tested, the cards are in my car resp.

Power Management implementation on Upstream for R-Car (especially Gen3) +09:23 < geertu> From Shimoda-san: +09:23 < geertu> --- start --- +09:23 < geertu> I would like to make a plan about Power Management implementation on +09:23 < geertu> Upstream for R-Car (especially Gen3). I didn't know the detail but BSP +09:23 < geertu> power management team has 130 local patches (wow!) to support power +09:23 < geertu> management for Gen3 BSP. So, I would like to do upstreaming about power +09:23 < geertu> management related code as well to reduce the local patches somehow. +09:23 < geertu> Morimoto-san suggested me that we have to integrate i2c_dvfs node at first. +09:23 < geertu> And then, we can implement each driver to support suspend/resume. +09:23 < geertu> --- +09:24 < geertu> (Ah, Khiem is replying to the email) +09:24 < geertu> If my memory serves me well, most patches for suspend are about saving/restoring register contents in each driver. +09:25 < shimoda> geertu: yes, the local patches have such code +09:25 < geertu> I'm afraid the way it's done in the BSP (hardcoded lists of devices in each driver) are not suitable for upstream. +09:26 < shimoda> geertu: i agree with you. +09:26 < morimoto> Yeah, no sense +09:26 < geertu> However, drivers that are also used on older (SH/SH-Mobile) SoCs may already have code upstream to save/restore or reinit registers during resume. +09:27 < geertu> E.g. sh-sci.c reinits registers, which is needed on SH/R-Mobile (removing the reinit breaks the port, I checked that a while ago) +09:29 < geertu> horms: Do you know if the BSP upport task classification project covered the suspend/resume patches in the BSP? +09:30 < horms> it does to the extent that I have tried to consistently mark them as the "Gen3 suspend to RAM" feature +09:30 < horms> I'm happy to refine that if it would be helpful +09:30 < geertu> Right, and they're called "Support DDR backup" +09:30 < horms> many are, yes +09:31 < shimoda> I asked Ito-san of a maneger about power management about this, he would like to do upstream some power management related code. thermal driver, cpu freq, cpu idle and cpu hotplug +09:31 < horms> I could provide a list in .csv file of just those patches. e.g. here or via email. it should be a single grep command away +09:32 < geertu> shimoda: According to Khiem's comments cpu freq, cpu idle, and cpu hotplug should be easy to complete. +09:32 < shimoda> and he are thinking that baylibre can do such upstreaming as well or not +09:32 < geertu> And Niklas is handling thermal +09:32 < shimoda> geertu: oh, i didn't read khiem san's email yet +09:33 < geertu> So the biggest hurdle is suspend to RAM. And we may want to try suspend-to-idle, too. +09:33 < geertu> s/suspend to RAM/non-standard suspend to RAM/ +09:34 < horms> Are Batlibre doing upstream work for us these days? +09:34 < neg> FWIW I plan to post v6 themral tomorrow +09:34 < horms> neg: does the thermal work include ESR? Yet? +09:35 < shimoda> neg: good news to me! thank you for this. +09:35 < neg> horms: ESR? +09:35 < horms> Emergency Shutdown +09:35 < shimoda> horms: yes, i think. (about Baylibre) +09:36 < horms> shimoda: thanks +09:36 < neg> horms: no, don't we need interrupt support first to support that? (new to thermal framework) +09:36 < morimoto> horms: We can forward some taks to Baylibre if PeriPeri can indicate it +09:37 < horms> neg: ok. EMS is the correct acronym. I only as as I see code for it in the BSP. +09:37 < horms> morimoto: ok, great! +09:38 < neg> I have nothing planed or in the pipeline for my base contract Q1 so if approprite I can help out here +09:39 < neg> horms: cool did not know about EMS and that it was in BSP, will have a look +09:39 < horms> neg: drivers/soc/renesas/rcar_ems_ctrl.c might be a good place to start looking +09:39 < horms> I have not inspected its contents +09:43 < geertu> I guess we cann hanle the remainder offline, cfr. the email thread? +09:44 < horms> sounds reasonable as Khiem-san is not present +09:44 < shimoda> I think so +09:45 < geertu> OK, thx +09:45 < geertu> Topic 3. >4G mem on M3-W +09:46 < horms> This seems to be going around in circles. +09:46 < horms> from my pov +09:46 < horms> We tried to manage things nicely +09:47 < horms> but due to unforseen circimatances we are no longer in control +09:47 < horms> i.e. the firmware enables the memory anyway +09:47 < geertu> Correct +09:47 < horms> Can we get closure on this by simply enabling things in DT - which should introduce no run-time change? +09:47 < geertu> Indeed. It behaves the same before and after +09:48 < horms> All currently enabled devices work, or at least have not been reported to be broken, right? +09:48 < geertu> (Linux handles the duplicates, as we add a second memory node, while u-boot adds a second reg set to the first memory node) +09:48 < geertu> Correct. +09:49 < geertu> DMA is impacted by swiotlb, using bounce buffers as rcar-dmac doesn't set the 40-bit DMA mask yet +09:49 < geertu> But that's the case with and without the >4G mem enablement patch, as it's enabled anyway +09:49 < horms> ok, so there is no change +09:50 < horms> do we have a channel where we can discuss this with Magnus? He has shown a paricular interest in this issue. +09:50 < geertu> Email? +09:50 < horms> sounds reasonable +09:50 < horms> do you wish to handle this? +09:52 < geertu> We already discussed this before with him. +09:52 < geertu> Can't find the email thread... +09:54 < horms> ok, perhaps we can follow up on this latter. +09:54 < horms> It would be nice to get some closure on this one +09:54 < geertu> OK, thread was "[PATCH 3/4] arm64: dts: renesas: r8a7796: Add DU device to DT" (sic) +09:54 < geertu> Let's just apply ;-) +09:55 < geertu> Topic 4.

or just media controller ? +09:25 < pinchartl> media controller only +09:25 < pinchartl> it's not related to any of my additional tasks in particular +09:25 < pinchartl> and it's taking more time from my base contract that I would like :-/ +09:26 < pinchartl> which brings me to the issues and blockers +09:26 < pinchartl> no blocker as such, but an issue +09:26 < morimoto> OK, I understand. +09:26 < pinchartl> I have too much work for my base contract +09:26 < morimoto> :) +09:26 < pinchartl> with all the maintainership and involvement in the V4L2 and DRM/KMS core +09:27 < pinchartl> they're not covered by any additional task, and they take a large amount of time +09:28 < pinchartl> given the current 50/50 split there isn't really room to handle the problem +09:28 < pinchartl> but I hope to be able to offload some of the work to Kieran if we can get budget +09:29 < pinchartl> kbingham: don't worry, I'll still handle the fights, you would mostly need to handle driver maintainership :-) +09:31 < kbingham> pinchartl: will I need more popcorn in that case :D +09:31 < pinchartl> :-) +09:31 < pinchartl> that's all for me +09:31 < pinchartl> morimoto: you're next +09:31 < morimoto> OK +09:31 < morimoto> I asked about ALSA SoC + HDMI + DT things to pinchartl, but couldn't get answer in time +09:32 < morimoto> so I worked other things this week +09:32 < morimoto> I posted few patches to ALSA ML for cleanup etc +09:32 < morimoto> I would like to solve HDMI sound things, but it seems difficult +09:32 < morimoto> Blocker is it. +09:33 < morimoto> pinchartl said that V4L2 side is thinking about .query method ? +09:33 < morimoto> but, I still wondering about it. +09:33 < pinchartl> it's a problem that spans multiple subsystems, so it should be implemented at the media controller level in my opinion +09:34 < pinchartl> but we're definitely not there yet and it will require a lot of work +09:34 < morimoto> does your "we" mean PeriMulti ? or V4L2 ? +09:35 < morimoto> or Linux ? +09:35 < pinchartl> Linux :-) +09:35 < morimoto> hehe, OK :) +09:35 < pinchartl> I know how I'd like to see this being implemented +09:35 < pinchartl> and it would require using the media controller framework in DRM/KMS and ALSA +09:36 < pinchartl> which means that we need to solve the MC core issues first +09:36 < morimoto> MC core ? +09:36 < pinchartl> otherwise it will not be possible to convince other subsystems to use it +09:36 < pinchartl> media controller core +09:36 < morimoto> Ahh OK +09:37 < morimoto> From ALSA side point of view, it need to care about non-HDMI and HDMI. So my question is that +09:37 < morimoto> Does your "MC" is related to both non-HDMI and HDMI ? +09:37 < morimoto> or only HDMI ? +09:37 < pinchartl> both +09:37 < morimoto> Hmmm +09:37 < morimoto> This means, existing ALSA itself need to be update ? +09:38 < morimoto> without HDMI support +09:38 < pinchartl> the problem is that we need to know about port types to parse and walk the DT OF graph +09:38 < pinchartl> that information isn't available in DT +09:38 < pinchartl> it is only known to drivers +09:38 < morimoto> Yes. +09:38 < morimoto> But, in existing ALSA, all are sound, no question. +09:38 < pinchartl> so we can't implement generic OF graph parsing and walking code without help from drivers +09:39 < pinchartl> we need a new API for drivers to provide the information +09:39 < morimoto> OK, I see. but I wonder, this means, I can't rework for HDMI sound at this point ? +09:40 < pinchartl> when an OF graph is limited to one of the ALSA, DRM and V4L2 subsystems only, we can implement a subsystem-specific solution +09:40 < pinchartl> but in the general case, we need a solution that is compatible will all three subsystems +09:40 < pinchartl> so we need a common object that can implement this API +09:40 < pinchartl> and at the moment we have none +09:41 < morimoto> My ? is related to here +09:41 < pinchartl> the best candidate in my opinion is the media_entity object, that would need to be used by all three subsystems +09:41 < pinchartl> HDMI sound doesn't involve V4L2 but it involves the two other subsystems +09:41 < morimoto> three = ALSA / DRM / V4L2 ? +09:41 < pinchartl> yes +09:42 < morimoto> If this OF graph is related to only multimedia case, right ? +09:42 < pinchartl> it should be yes +09:42 < morimoto> If non multimedia want to use OF, it will not be "media_entity" +09:42 < morimoto> Hmm... +09:43 < pinchartl> correct, but non-multimedia devices don't involve ALSA :-) +09:43 < pinchartl> I'm open to other proposals, but in any case I believe this will be lots of work +09:43 < morimoto> But can use OF-graph ? +09:44 < morimoto> Is this related to know "which port is what type" ? +09:44 < morimoto> = OF-graph +09:44 < pinchartl> it's related to OF graph parsing +09:44 < pinchartl> not only about port type +09:45 < pinchartl> a DT node has ports that describe its external connections +09:45 < morimoto> OK, if so, naming should use "media" ? +09:45 < morimoto> should not +09:45 < pinchartl> but doesn't include information that describe the internals of the IP core +09:45 < pinchartl> that's the information missing at the moment +09:46 < pinchartl> we could use a different namespace, implement the API at a different level +09:46 < pinchartl> I'm not sure where though +09:46 < morimoto> I understand basic ideas +09:47 < morimoto> I wonder where do you (or other guys ?) discuss this topics ? +09:47 < morimoto> I mean which ML ? +09:47 < morimoto> ALSA side guys need to join it +09:47 < pinchartl> MC discussions usually happen on the linux-media mailing list +09:48 < pinchartl> if we implement the API somewhere else, I don't know +09:48 < morimoto> This is "OF-graph" releated method, right ? +09:48 < morimoto> we can get information from this new API +09:48 < morimoto> not only type, but many information +09:49 < pinchartl> yes, we need more than just the type +09:49 < morimoto> But this OF-graph use is not only V4L2, ALSA. +09:49 < pinchartl> if you have a DT node with 4 ports +09:49 < pinchartl> two inputs and two outputs +09:49 < morimoto> Other device can use it ? +09:50 < morimoto> I don't know who, but not only media I think ? +09:50 < pinchartl> it could be that internally input 1 is connected to output 1 and input 2 to output 2, creating two separate unrelated pipelines +09:50 < pinchartl> when parsing the graph we'd need to know about that +09:50 < pinchartl> possibly, but at the moment only multimedia devices use OF graph +09:51 < morimoto> OK +09:51 < morimoto> So, this means, my HDMI sound can't upstream at this point, right ? +09:52 < morimoto> It will be step 3 or later +09:52 < morimoto> not step 1 +09:53 < pinchartl> yes, I think we're blocked at the moment +09:53 < morimoto> OK. can you update multimedia/todo ? +09:53 < morimoto> It is not my fault :P +09:53 < morimoto> It is = delaying +09:54 < pinchartl> obviously another approach would be to use a different style of DT bindings that would be easier to handle. lots of options are possible. we're at a brainstorming stage, someone needs to drive the effort with all the upstream subsystems. it's lots of work :-/ +09:54 < pinchartl> sure, it's not your fault :-) +09:55 < morimoto> Hehe :) thanks +09:55 < pinchartl> I'll remove the target version from the todo list +09:55 < morimoto> So, I will start other tasks. +09:55 < morimoto> Thanks +09:55 < pinchartl> well +09:55 < pinchartl> if you move to other tasks +09:55 < pinchartl> who will solve this problem ? :-) +09:56 < morimoto> Oops, OK +09:56 < morimoto> I am 1 of un-lucky guys :) +09:56 < pinchartl> welcome to my world :-) +09:56 < morimoto> Hehe :) +09:57 < morimoto> I think I want to talk to you in F2F in some day +09:57 < morimoto> Maybe ELC +09:57 < morimoto> ? +09:57 < morimoto> Do you go there ? +09:57 < pinchartl> I will be there +09:57 < morimoto> OK +09:57 < pinchartl> I've submitted a talk proposal, I hope it will be accepted +09:58 < morimoto> OK +09:58 < morimoto> that's it from me +09:58 < pinchartl> it's quite a lot already :-) +09:58 < pinchartl> thank you +09:58 < pinchartl> (now I have to summarize this in the report...) +09:59 < pinchartl> I assume that your plans for the next two weeks is holidays ?

I think I change my mind + and intend to go if I can find a good flight :-) +<morimoto> at this point, maybe 20th - 24th +<neg> so that would leave the 20th and 24th for possible meeting days ? + [17:49] +<morimoto> that the reason why I'm asking about meeting :) [17:50] +<morimoto> If we have meeting, the plan will be changed +<pinchartl> I will arrive on the 18th and leave on the 25th +<pinchartl> the 19th (Sunday), 20th and 24th are currently free +<pinchartl> but I expect a V4L2 meeting to be scheduled, likely on the 20th +<morimoto> pinchartl: Do you think "media-layer" will be discussed on V4L2 + meeting ? [17:52] +<pinchartl> what do you mean by media-layer ? +<morimoto> V4L2 + ALSA need media-layer for OF-graph ? +<pinchartl> probably not [17:53] +<pinchartl> it will likely be focussed on core media controller problems +<neg> OK, in order to be able to book flights maybe we can aim to keep the + 24th open for a possible meeting if the contract situation is sorted + out? My understanding is that nither Geert nor Wolfram will attend ELC + so MM is the only possible meeting at that time? [17:54] +<pinchartl> the 24th would be nice +<pinchartl> if you can be there on both the 20th and the 24th it would give us + some flexibility +<pinchartl> and you could join the V4L2 meeting when it will be scheduled :-) + [17:55] +<neg> cool then I try to book flight to arrive 19 and leave 25 +<morimoto> cool. I will re-schedule for ELC +<neg> yes if possible I would like to attend the V4L2 meeting, without + periperi scheduling collision :-) +<pinchartl> last topic [17:56] +<pinchartl> Topic 4. Next meeting +<pinchartl> I will be on holidays in two weeks from now +<pinchartl> so we can schedule a meeting in a week +<pinchartl> or in three weeks +<pinchartl> one week is likely too short as we have no contract at the moment +<pinchartl> 3 weeks seems better +<pinchartl> but that might collide with Kieran's travel plans for the FOSDEM + [17:57] +<pinchartl> (which would give Kieran a good excuse to not attend the meeting + :-)) +<pinchartl> would wednesday 2017-02-01 at 08:00 GMT / 09:00 CET / 10:00 EET / + 17:00 JST work ? +<kbingham> it does cut it close ... but its actually probably just about + do-able ... as long as I book my taxi to pick me up at the end of + the meeting :D [17:58] +<pinchartl> :-) +<kbingham> So yes, fine by me. +<pinchartl> if you have to skip it's not an issue +<pinchartl> does it work for everybody else ? +<uli___> ok for me +<neg> OK for me [17:59] +<morimoto> OK for me too +<pinchartl> perfect, it's agreed then +<pinchartl> I propose adjourning this meeting [18:00] +<pinchartl> does anyone second ? +<kbingham> seconded and running downstairs to make tea :D +<pinchartl> :-) +<pinchartl> meeting adjourned +<pinchartl> thank you everybody for attending +<pinchartl> have a nice day/evening [18:01] +<morimoto> Thanks +<uli___> see you +<neg> thanks all diff --git a/wiki/Chat_log/20170116-io-chatlog b/wiki/Chat_log/20170116-io-chatlog new file mode 100644 index 0000000..3cf4ad2 --- /dev/null +++ b/wiki/Chat_log/20170116-io-chatlog @@ -0,0 +1,148 @@ +--- Log opened Mon Jan 16 08:59:32 2017 +08:59 -!- wsa_ [~wsa@p54B33FFD.dip0.t-ipconnect.de] has joined #periperi-io +08:59 -!- Irssi: #periperi-io: Total of 5 nicks [1 ops, 0 halfops, 0 voices, 4 normal] +08:59 -!- Irssi: Join to #periperi-io was synced in 1 secs +09:00 < wsa_> hey guys! +09:00 <@morimoto> hi +09:00 -!- shimoda [~shimoda@relprex3.renesas.com] has joined #periperi-io +09:00 < neg> horms: I accidently sent my ABC awnsers from my private email address to periperi, I have now resent the anwsers but feel free to delete and not to add my private email to the periperi whitelist :-) +09:00 -!- morimoto [~user@relprex3.renesas.com] has left #periperi-io ["ERC Version 5.3 (IRC client for Emacs)"] +09:00 < neg> wsa_: hi +09:00 < horms> neg: ok, will do +09:01 < neg> horms: thanks +09:01 -!- geertu [~geert@d54C189FD.access.telenet.be] has joined #periperi-io +09:01 < wsa_> that reminds me, simon you can remove the wsa-dev address from periperi as well +09:01 < geertu> Bummer, I was in #peripero-io +09:01 < horms> wsa_: sure +09:01 < wsa_> wsa@the-dreams.de seems to be back at full strength +09:02 < wsa_> geertu: "we are the popular front" +09:02 < wsa_> :D +09:03 -!- Irssi: #periperi-io: Total of 6 nicks [0 ops, 0 halfops, 0 voices, 6 normal] +09:04 < wsa_> ok, let's start +09:04 < wsa_> thanks for all the updates +09:04 < wsa_> despite holidays, there were some things going on :) +09:05 < wsa_> i have a few questions +09:05 < wsa_> first one about USB & IPMMU, I lost track a little of it +09:05 < wsa_> shimoda: does a workaround exist meanwhile? +09:06 < shimoda> wsa_: a workaround exist for some devices +09:07 < wsa_> and the SD workaround is basically the same issue +09:07 < wsa_> IPMMU issue +09:07 < wsa_> ? +09:08 < shimoda> wsa_: no.

PFC/GPIO entanglement on RZ/A1H +09:49 < jmondi> yup... +09:49 < jmondi> so I have prepared a sum-up of the discussions on mailing lists: https://nopaste.me/view/raw/ee7a1180 +09:50 < jmondi> I guess the final question, even before deciding if PFC and GPIO should be merged in a single driver is: do we want to continue pushing this group-based implementation for PFC? +09:51 < pinchartl> jmondi: I wouldn't for RZ/A +09:51 < pinchartl> we have to for R-Car, as the hardware has the concept of groups +09:51 < jmondi> I have received many feedbacks (from Chris and Laurent mainly) on how it would be better to start with a new pin-based pinctrl implementation... Of course this has to be planned, so I would like to discuss this with you all... +09:52 < jmondi> pinchartl: sorry, go on please... +09:52 < pinchartl> I'm done :-) +09:53 < geertu> I have two comments +09:53 < geertu> 1) For R-Car, we have to keep on using groups, as Laurent says +09:54 < geertu> 2) I believe RZ/A is low-priority work for us. So going for the full "rz-pfc/ driver infrastructure" may be going to far, for now. +09:54 < geertu> It would be good to have a simple RZ/A driver upstream, though. +09:55 < geertu> If more users show it, that simple driver can be turned into a "rz-pfc/ driver infrastructure" +09:55 < jmondi> geertu: 1) I never wanted to touch the existing code-base for r-car devices :) +09:55 < geertu> (but it needs a different name than "rz", due to RZ/A vs RZ/G vs RZ/T ;-) +09:55 < horms> rza seems useful from my pov +09:56 < geertu> About memory, RZ/A SoCs are available with 3 or 9 MiB of builtin SRAM, and that may be all on some boards. +09:57 < geertu> Cfr. build you own Cortex A9 board with an SoC in QFP package and 5 external components ;-) +09:57 < jmondi> geertu: according to Chris yes, that's why a run-time creation of groups and functions, as pinctrl-single is doing, may be problematic +09:58 < pinchartl> jmondi: do we have to create all groups and functions at init time ? could we create them on-demand, just for the ones referenced in the device tree ? +09:59 < geertu> jmondi: I haven't looked at the RZ/A PFC driver in the BSP yet... +09:59 < jmondi> pinchartl: that's what happens... the (now moved to core) functions to parse the dts and create groups and functions creates groups only for pins configured in the device tree +09:59 < pinchartl> ok +10:00 < pinchartl> how much memory is that ? +10:00 < pinchartl> compared to the memory allocated by the sh-pfc driver ? +10:00 < jmondi> geertu: there are many of them. Chris has a 3.14 one which does not use device tree yet. Some customer ported it to use DTS and the result is the ABI reported in the file I shared +10:01 < geertu> jmondi: OK +10:01 < jmondi> pinchartl: I guess problem here is that it is run-time memory, compared to huge tables that increases the kernel image size +10:01 < geertu> jmondi: About "tweak pinctrl-single to remove hw specificities: not sure what pinctrl-single maintainer think". Usually maintainers are happy to see that happen +10:02 < geertu> jmondi: Well, the run-time tables will be smaller. The static cables can't be freed anyway. +10:02 < jmondi> geertu: that may be an attempt that ends up in nothing though... Before even trying wouldn't it be better to ask Tony/Linus if this is acceptable? +10:04 < pinchartl> jmondi: and I assume the memory-constrained RZ/A use cases use XIP +10:04 < pinchartl> but sh-pfc also allocates memory at runtime +10:04 < pinchartl> it would be useful to check how much +10:04 < pinchartl> I don't think we can reuse the pinctrl-single driver +10:05 < pinchartl> as it is based on the assumption that one pin will be controlled by a single register +10:05 < pinchartl> we can, however, implement a driver that uses a similar concept +10:06 < jmondi> pinchartl: that's why I thought about having a platform-specific part to hook into pinctrl-single: something like "give mode and configuration and I take care of setting register opportunely for my platform" +10:06 < jmondi> but I understand there's a lot of overhead there +10:07 < pinchartl> many options are possible +10:07 < pinchartl> I'd start with a custom driver, to evaluate the memory impact +10:07 < pinchartl> if it's acceptable, then we could try to reuse code from pinctrl-single +10:08 < pinchartl> if it's not, there's no point :-) +10:08 < jmondi> and I must say I would prefer a smaller driver, with maybe some generated tables at least for validation (ie. not all ports support all 8 modes) +10:09 < jmondi> pinchartl: would that custom driver be a (PFC + GPIO) driver in you opinion, right? +10:09 < pinchartl> I think it should be, given how the hardware is architectured +10:10 < jmondi> pinchartl: the interleaved registers thing is a pain :( +10:11 < pinchartl> only if you want one DT node per bank +10:11 < pinchartl> with a single DT node, it's no big deal +10:12 < jmondi> pinchartl: right.. +10:12 < geertu> A simple combined PFC and GPIO driver makes sense +10:14 < jmondi> geertu: not using sh-pfc/, right? +10:14 < geertu> jmondi: Yep +10:14 < geertu> drivers/pinctrl/renesas-rza1.c +10:15 < jmondi> geertu: ok, let me report these feedbacks to Magnus and see how/when I could work on this... +10:16 < geertu> OK. Time to move on? +10:16 < jmondi> also, I am doing this on a remote board, which is a bit painful... are there other boards with RZ/A SoC, as I understood genmai is available in Japan only +10:17 < jmondi> yeah, sorry... go on, I'll sort this out with Magnus +10:17 < geertu> GR-PEACH +10:18 < geertu> It has the internal 10 MiB only though, unlike Genmai +10:18 < geertu> DigiKey says 117 EUR +10:19 < geertu> (and 409 for the LCD panel shield :-( +10:19 < geertu> I believe Wolfram has a Genmai, too +10:19 < jmondi> geertu: thanks! let's see if I can get one... +10:20 < jmondi> without the LCD panel :) +10:20 < geertu> Doh... +10:21 < geertu> Next meeting will be in real life in Brussels, the Friday before FOSDEM +10:22 < geertu> If you haven't already done so, please confirm your (un)attendence by the morning of Wednesday, January 18th. +10:23 < jmondi> geertu: where should we confirm that? Is there a form or a "I'll be there" is enough? +10:24 < geertu> jmondi: Just let me know.

I've also worked through the 'pseudo code' from Renesas, and made this compile so I could better understand each of it's actions. +09:09 < kbingham> From this I've added phase calculation into the UDS entity, and I'm trying to rework the algorithm so that each entity "controls it's own fate" and performs it's part of the algorithm. (WPF determines output windows, UDS determines scaling factors, RPF determines source chroma recovery). To achieve needs per partition cropping on each entity - something to talk about F2F later today/tomorrow :D +09:10 < kbingham> Next: FOSDEM, and I'm hoping to get a last minute snowboarding holiday in the school half-term with Keri (13-17th), and more work on PA, and VSP-tests. +09:10 < kbingham> Blockers - only that I want to go through partition algorithm design with Laurent, which is conveniently possible in the next couple of days. +09:10 < kbingham> (pre-written due to time constraints :D ) +09:11 < kbingham> EOT +09:11 -!- morimoto [~user@relprex1.renesas.com] has joined #periperi +09:11 < pinchartl> thank you +09:11 < pinchartl> hello Morimoto-san +09:11 < morimoto> Hi +09:11 < pinchartl> we have just started with Kieran's update +09:11 < morimoto> Oops ? already started ?? +09:12 < kbingham> morimoto: my fault- I have a plane to catch :D +09:12 < pinchartl> has Japan moved its time zone by 15 minutes without any notice ? :-) +09:13 < morimoto> I'm booking today's meeting started from 17:30, now Japan is 17:10 +09:13 < pinchartl> I think I've sent the invitation starting from 17:00 +09:13 < pinchartl> but no worries, you're here :-) +09:13 < pinchartl> I'll go next to give you a bit of time to prepare +09:13 < morimoto> Grr, sorry about that +09:13 < pinchartl> since last meeting +09:14 < pinchartl> I've continued advancing the HDMI output driver towards merging +09:14 < pinchartl> there's few blockers left +09:14 < pinchartl> Neil Armstrong from BayLibre has submitted a patch series to prepare the dw-hdmi driver to be used in Amlogic SoCs.

Since last time +09:22 < morimoto> I talked with Rob (= OF-graph maintainer) and ML people about ALSA SoC OF-graph DT bindings, and almost OK I believe. +09:22 < morimoto> I posted OF-graph ALSA SoC support patch-set this week. +09:22 < morimoto> I noticed we can solve HDMI sound port detection issue of OF-graph if we have new ALSA SoC function (before I produced "type=sound" property for it. Laurent indicated media-controller for it). I implemented it, and it works. +09:22 < morimoto> I got few BSP team request for you guys ;) +09:22 < morimoto> B. Until next time +09:23 < morimoto> I will post HDMI sound patch-set if OF-graph patch-set was accepted. +09:23 < morimoto> And paper work for MAX Camera +09:23 < morimoto> C. Blockers +09:23 < morimoto> There is no response from Rob +09:23 < morimoto> CSI2 camera export needs Happy lovely paper work +09:23 < morimoto> --EOF-- +09:23 < morimoto> About MAX Camera, BSP team want to have this support until 3/E, maybe this is not realistic ? +09:23 < morimoto> Export paper work takes more time, and no develop time for you guys :( +09:23 < morimoto> And this MAX Camera will be rental, we need to back it to BSP team. +09:23 < morimoto> So, my plan is we will buy it. +09:24 < morimoto> But, it seems buying will takes time +09:24 < morimoto> some plan we have +09:24 < morimoto> 1) +09:24 < morimoto> send rental camera to you guys +09:25 < morimoto> and Renesas buy it in parallel +09:25 < morimoto> And someday, we will switch +09:25 < morimoto> or +09:25 < morimoto> 2) +09:25 < morimoto> I will ask you guys to buy it from Europa +09:25 < pinchartl> thank youcan it be bought easily ? do you know what the lead time is ? +09:25 < morimoto> but, 2) is not good for time limit +09:26 < morimoto> Acorrding to HW guys, if you buy it today, you can get it 3/E +09:26 < pinchartl> :-) +09:26 < morimoto> Now we are considering about it +09:26 < morimoto> Ahh +09:27 < pinchartl> I'm fine with that, but I suppose the BSP team iisn't :-) +09:27 < morimoto> about MAX chip datasheet, it is under NDA +09:27 < morimoto> We are solving export paper work +09:28 < pinchartl> can we get the MAX9286 datasheet under NDA ? +09:28 < morimoto> pinchartl: if we can avoid BSP team's time limit, can I ask you buy it from Europe ? +09:28 < morimoto> We will get more detail. URL, cost, serial number etc... +09:29 < pinchartl> morimoto: sure, assuming that Maxim will sell it to us (as the documentation is under NDA there could also be restrictions on buying the hardware) +09:29 < morimoto> pinchartl: about MAX datasheet, yes, we can get it nunder NDA. we need more detail infromation from HW guys. +09:30 < morimoto> It needs additional board + camera. camera is very generic. no problem +09:30 < pinchartl> if you tell us what to buy we can certainly buy it, no problem with that +09:31 < morimoto> but, board is R-Car special. We need special interface guy (?) +09:31 < morimoto> pinchartl: yes, thanks +09:31 < morimoto> We are now planing how to solve this issue. +09:31 < morimoto> thats it from me +09:32 < pinchartl> the interface board is a custom PCB from Renesas, right ? +09:32 < morimoto> maybe, I don't know detail yet +09:33 < pinchartl> I would assume so +09:33 < pinchartl> we will need that PCB +09:33 < pinchartl> when do you expect to have information on what is needed ? +09:34 < morimoto> Now, HW guys is collecting information +09:34 < morimoto> BSP team -> HW guys -> ??? +09:34 < morimoto> I don't know how long +09:35 < pinchartl> ok +09:35 < pinchartl> we *could* try to get different hardware to work on +09:35 < pinchartl> but I think it will take longer +09:35 < pinchartl> as we would likely have to develop an interface PCB anyway +09:35 < morimoto> I guess is this related to 2nd Q1 SoW ? +09:36 < neg> If there is a upstream driver for a CSI-2 transmitter that supports multiple channels that might still be less time to develop a interface PCB +09:36 < morimoto> If so, when do you need it for Q1 2nd SoW ? +09:37 < morimoto> I guess, we can collect many information this and next week (?) +09:37 < morimoto> And start export paper work +1 or +2 weeks +09:38 < morimoto> And ship it to Europe, it take 1 week ? +09:38 < morimoto> this is *BEST* case +09:38 < pinchartl> this brings us to the next topic, VIN/CSI-2 planning :-) +09:38 < pinchartl> I don't think 3/E is a reasonable target +09:38 < morimoto> Hmm.. yes +09:38 < pinchartl> as Niklas explained in his last e-mail, there is lots of work needed +09:38 < morimoto> Yes, yes, I know +09:38 < pinchartl> we could possibly produce a prototype by 3/E +09:38 < pinchartl> *if* we can assign enough developers on this +09:39 < morimoto> without HW ? +09:39 < pinchartl> Niklas (unless that has changed) works 50% for Renesas +09:39 < pinchartl> (25% for the base contract and 25% for the additional tasks) +09:39 < pinchartl> that's now enough time until 3/E to implement a solution +09:39 < pinchartl> no, with hardware +09:39 < morimoto> OK +09:39 < pinchartl> hardware isn't needed at the very beginning +09:39 < pinchartl> but we'll need it for testing +09:40 < morimoto> and remote machine is not enough ? +09:40 < pinchartl> it depends on the hardware, whether it can be controlled remotely +09:40 < pinchartl> I don't expect things to work out of the box +09:40 < pinchartl> remote access has a high latency +09:40 < morimoto> OK +09:41 < pinchartl> 5 minutes to boot a new kernel +09:41 < morimoto> Ahh, not good +09:41 < pinchartl> as we'll need lots of tests to debug the code, that would slow things up +09:41 < morimoto> I will do my best for you guy ;) +09:41 < pinchartl> I mean slow things down :-) +09:41 < pinchartl> thank you +09:41 < pinchartl> another thing +09:41 < neg> thank you :-) +09:42 < pinchartl> as I said, producing a prototype for 3/E requires lots of work +09:42 < pinchartl> Niklas won't have enough time alone +09:42 < pinchartl> so we'll need to work together +09:42 < pinchartl> Kieran and I can help +09:42 < pinchartl> but then we won't have enough time to solve the VSP/DU flicker issues +09:42 < morimoto> I think BSP team's planning is already broken. So I can tell it to them +09:43 < pinchartl> they have to pick the priority +09:43 < pinchartl> the second half of Q2 is one month +09:43 < pinchartl> 20 days +09:43 < pinchartl> as Niklas is assigned to Renesas at 50%, that's 10 days for him +09:43 < pinchartl> 5 days of base task, 5 days of additional task +09:44 < pinchartl> it makes no sense to split that between VIN and something else +09:44 < pinchartl> so if we need to focus on VIN, I'd like Niklas to spend all his time on VIN in the second batch of Q1, and in Q2 +09:44 < pinchartl> otherwise we won't move forward if we split this in 5 days tasks here and there +09:45 < pinchartl> another thing +09:45 < pinchartl> if we assign enough developers to this 3/E might be possible for a prototype +09:45 < pinchartl> *but* +09:45 < pinchartl> it really means 3/E +09:45 < pinchartl> we can't do it for 3/M +09:45 < pinchartl> which is when Jinzai expects reports +09:46 < pinchartl> in that case I'll want to send reports at 3/E +09:46 < pinchartl> as spending time on reports for 3/M while we rush to finish the code for 3/E makes absolutely no sense +09:47 < morimoto> I guess we can avoid 3/E limitation for VIN for now. And I think I need to talk to my Boss about Niklas time ? +09:47 < pinchartl> and to Niklas and Magnus too I assume :-) +09:47 < morimoto> Ahh yes.

The real issue here is auto-gain configuration +10:05 < wsa_> is there a "most flexible" solution? +10:06 < jmondi> eh, I wish I know what that would be... supporting most uses cases implies creating a quite sluggish interface in sysfs, where userspace is required to take care of auto-gain settings +10:07 < jmondi> a sort of calibration process +10:08 < jmondi> on the other side, we can present the "processed" values from a single attribute, performing auto-gain setting in kernel space, but that would not support buffered reads, and will make complex implementing it in future +10:09 < jmondi> and that's where my question come from: Do we have any idea what would be a plausible sampling frequency on that device (if we do have defined use-cases for that chip specific to our platforms) +10:09 < wsa_> i see +10:10 < geertu> jmondi: You could ask BayLibre (Neil Armstrong) what sampling frequency they find useful for ACME with their tools +10:10 < wsa_> things I can think of: +10:10 < wsa_> a) ask on linux-pm if they have an idea what frequency is needed +10:11 < wsa_> or BayLibre ;) +10:11 < wsa_> and b) I don't think implementing complex userspace configuration without a clear use-case is benefitial +10:11 < geertu> jmondi: I never use the GUI tools that draw graphs +10:12 < geertu> w.r.t. b) yes, KISS +10:12 < wsa_> exactly +10:13 < jmondi> geertu: I didn't even know it existed. Mostly, I don't know what tools are out there that polls on a device like this, that's why I don't have idea about typical use cases +10:13 < wsa_> which would lead to chosing the "simpler" method unless we can create the use case +10:14 < wsa_> jmondi: does it help you a little? +10:14 < jmondi> geertu: wsa_: Ok, I'll ask a bit around, if I'm not pointed to any monitoring tool with strict time requriements out there, I'll go for the simple solution +10:15 < jmondi> wsa_: yes, thank. Sometimes is easy for me to get lost, and need some directions to find out where to ask informations or where to look at :) +10:15 < wsa_> sounds good to me for now +10:15 < geertu> jmondi: http://baylibre.com/acme/ shows some screenshots.

HDMI Monitor say "No signal" +09:21 < dammsan> pinchart: nothing to report here +09:21 < pinchartl> morimoto: that will need to be debugged and fixed +09:22 < pinchartl> morimoto: I never claimed that the code is bug-free :-) +09:22 < morimoto> Laurent side can't reproduce this, right ? +09:22 < pinchartl> so far I haven't been able to +09:22 < morimoto> OK, it will be never-endding-story +09:22 < pinchartl> but I can try again if someone gives me a clear test procedure +09:22 < dammsan> morimoto: maybe we can revisit next quarter? +09:22 < morimoto> By SoW do you mena ? +09:23 < morimoto> s/mena/mean/ +09:23 < pinchartl> note that the latest patch series should improve the hotplug use cases, so maybe the problem has been fixed +09:23 < pinchartl> (maybe...) +09:23 < dammsan> morimoto: no, when pincharl is back from vacation +09:23 < morimoto> Ahh, OK, np +09:23 < morimoto> not urgent, but I wanted to tell +09:24 < pinchartl> thank you +09:24 < dammsan> morimoto: thanks for sharing +09:24 < pinchartl> morimoto: your turn +09:24 < morimoto> OK +09:24 < morimoto> Before my ABC, I have request to Laurent (before vacation :) +09:25 < pinchartl> go ahead +09:25 < morimoto> BSP team is waiting answer from you, about +09:25 < morimoto> Subject: About Graphics Performance +09:25 < morimoto> Date: Wed, 8 Feb 2017 10:04:54 +0900 +09:25 < morimoto> Please makes BSP team happy :P +09:25 < pinchartl> that's the second topic for today, as I mentioned when we started the meeting :) +09:25 < morimoto> OK +09:25 < morimoto> A) What have I done since last time: +09:25 < morimoto> - I posted OF-graph patch again. +09:26 < morimoto> - I created 40bit Descriptor Mode on Audio DMAC +09:26 < morimoto> - Forwarded BSP team question to Multimedia member +09:26 < morimoto> B) What I plan to do till next time: +09:26 < morimoto> - Missing 8ch support on Audio (not urgent) + +09:26 < morimoto> - Consider Tx/Rx interrupt sharing (not urgent) +09:26 < morimoto> last one was I reported by email, but finished :P +09:26 < morimoto> C) Problems I have currently: +09:26 < pinchartl> :-) +09:26 < morimoto> - I want to post HDMI sound patch-set which is based on +09:26 < morimoto> posted OF-graph patch-set. Rob's response is... +09:27 < morimoto> D) Posted/Accepted bugfix patches: +09:27 < morimoto> Subject: [PATCH] ASoC: rsnd: fix sound route path when using SRC6/SRC9 +09:27 < morimoto> Subject: [PATCH] ASoC: rcar: avoid SSI_MODEx settings for SSI8 +09:27 < morimoto> --EOF-- +09:27 < pinchartl> do I need to list those patches or will they be picked up by your script ? +09:28 < morimoto> my script is very clever, more than me :) +09:28 < morimoto> so, D) is no longer needed on meeting, actually +09:28 < pinchartl> :) +09:28 < pinchartl> so Rob said "..." ? +09:29 < morimoto> no response from him +09:29 < morimoto> Am I mistaken +09:29 < morimoto> ? +09:29 < morimoto> Rob is no maintener ? +09:29 < morimoto> s/no/not/ +09:29 < pinchartl> he's a DT maintainer +09:29 < pinchartl> I expect him to be busy this week +09:29 < pinchartl> with Linaro Connect in Budapest +09:30 < morimoto> Ahh... +09:30 < pinchartl> so maybe you should try to ping him next week ? +09:30 < morimoto> OK, will do. thanks +09:31 < pinchartl> you're welcome +09:31 < pinchartl> next, neg +09:31 < neg> a) Started to rework VIN driver for Gen3 to only use media graph and let userspace handle subdevice configuration and supported BSP team with investigation + regarding the VIN. +09:31 < neg> b) Complete the VIN Gen3 rewrite. +09:32 < neg> c) None +09:32 < neg> d) None +09:32 < neg> -- EOT of short version, see reply to meeting invatation for more details -- +09:32 < morimoto> Ahh, neg and pinchartl, I sent camera board check request +09:32 < morimoto> please check it +09:32 < pinchartl> should I ignore the issue reported in the e-mail then ? +09:33 < neg> morimoto: I checked and replied to it :-) +09:33 < morimoto> thanks +09:33 < pinchartl> next, uli___ + +09:34 < uli___> i tried to get a mainline kernel to run on the acer chromebook r13 +09:34 < uli___> to give us a model organism for gpu development +09:34 < uli___> see my status update on how that has failed so far... +09:34 < uli___> the next thing i'm going to do is put together a prototype for a OV10365/MAX9271/MAX9286 camera setup +09:35 < uli___> that's it for now +09:35 < uli___> driver prototype, that is +09:35 < uli___> i'm not completely awake yet :) +09:35 < pinchartl> :-) +09:35 < neg> for the chromebook lack of serial console, is netconsole an option? +09:36 < pinchartl> neg: nope, we have no network +09:36 < pinchartl> the problem at hand is to get a kernel to boot at all +09:36 < pinchartl> it certainly doesn't boot to UI +09:36 < neg> I see than I'm out of ideas :-( +09:36 < pinchartl> and doesn't boot to the network either +09:36 < pinchartl> I still thing our best option is to get this think opened and locate a serial port +09:37 < pinchartl> dammsan: any other idea ? +09:38 < geertu> uli___: "blinky LEDs are behind the embedded controller" +09:38 < uli___> yes +09:38 < geertu> uli___: Can you talk to them through the EC? +09:39 < geertu> (on FOSDEM, there was a presentation about the EC) +09:39 < dammsan> i just asked same thing as geertu over email +09:39 < dammsan> getting an LED to blink would be very nice +09:39 < dammsan> i can take it from there +09:40 < uli___> might work +09:40 < uli___> but the ec driver isn't trivial either +09:41 < pinchartl> why don't anyone listen when I say we should crack the case open ? :-) +09:41 < dammsan> perhaps it is possible to scale it down somehow? +09:41 < uli___> i think writing custom code that talks to the ec is more likely to succeed +09:41 < dammsan> uli___: what do you think about opening it up? +09:42 < pinchartl> there might even be a jtag port inside +09:43 < uli___> i don't know. i'm afraid it might end up open forever, with an unpredictable degree of functionality :) +09:43 < pinchartl> open forever isn't a big issue +09:43 < dammsan> you need to press a key to boot +09:44 < pinchartl> the unpredictable degree of functionality is a bit more annoying +09:46 < pinchartl> so what's the plan there ? +09:46 < uli___> i can look into getting the ec leds to blink +09:47 < dammsan> my hope is that ulrich will hand over his result to me including LED blink code +09:48 < pinchartl> so do you want to go for one more round and try to talk to the EC from a mainline kernel ? +09:49 < dammsan> i can port it +09:49 < dammsan> i've done things like that before +09:49 < dammsan> no biggie +09:49 < pinchartl> I don't have high hopes there, but if you think it's useful, it's your choice :) +09:49 < dammsan> seems our best choice right now +09:49 < pinchartl> I *still* believe the best choice is to open it up +09:49 < dammsan> but please note that next quarter additional batch 1 will not cover the GPU +09:50 < dammsan> to give some time to figure things out +09:50 < geertu> Do we know what's expected to be found inside? +09:50 < dammsan> pinchartl: how about we compete about it in parallel once you are back from vacation? +09:51 < dammsan> =) +09:51 < pinchartl> dammsan: no, thanks, I have lots of work on DU, VSP and VIN already :) +09:51 < dammsan> i'll take a blinky LED over unknown hardware any day +09:51 < dammsan> there you go =) +09:51 < dammsan> answer is pretty clear +09:52 < pinchartl> ok, let's put that on hold then +09:52 < pinchartl> this finishes the status update portion of this meeting +09:53 < pinchartl> Topic 2. Graphics Performance issue +09:53 < pinchartl> this was reported by the BSP team +09:54 < pinchartl> who noticed a performance regression between v4.6 and v4.9 +09:54 < pinchartl> due to commit f1f0197796a61e5548af32606f15bcf8cf353267 +09:54 < pinchartl> drm: rcar-du: Map memory through the VSP device +09:54 < pinchartl> and commit 60facdbd4d62b863917263bb1ad77bbb4a4a9369 +09:54 < pinchartl> v4l: vsp1: Add API to map and unmap DRM buffers through the VSP +09:55 < pinchartl> those two patches ensure proper operation of the DU + VSP on Gen3 when the VSP is behind an IOMMU +09:55 < pinchartl> this is required, but leads to an additional cache flush +09:55 < pinchartl> which in turn degrades performances +09:56 < pinchartl> (~300µs per frame) +09:56 < pinchartl> the cache flush is needed +09:57 < pinchartl> in the sense that, in the general case, the CPU will render to the buffer +09:57 < pinchartl> (of course optimizations are possible when the CPU doesn't touch the buffer, but that's a separate topic) +09:57 < pinchartl> *but* +09:58 < pinchartl> the memory is currently mapped uncached to the CPU +09:58 < pinchartl> so as long as this doesn't change, we could skip the cache handling operations +09:59 < pinchartl> the DMA mapping API supports skipping cache management +09:59 < pinchartl> when the DMA_ATTR_SKIP_CPU_SYNC flag is set +09:59 < pinchartl> s/flag/attribute flag/ +10:00 < pinchartl> we should experiment with that +10:00 < pinchartl> I can give it a try after coming back from vacation +10:00 < pinchartl> and I'll reply to the BSP team's e-mail today with this information +10:00 < pinchartl> morimoto: does this answer your question ? +10:01 < morimoto> Yes, maybe + +10:01 < morimoto> something feedback to BSP team makes them happy at this point +10:01 < morimoto> I don't know how urgent it is +10:02 < morimoto> do you think it will be long-term problem ? +10:02 < pinchartl> note that those two commits are not upstream +10:02 < pinchartl> they're part of the IOMMU support work for DU+VSP +10:02 < pinchartl> but haven't been merged yet +10:03 < pinchartl> hopefully it won't be a long-term issue +10:03 < pinchartl> setting the DMA_ATTR_SKIP_CPU_SYNC attribute might be all we need +10:03 < pinchartl> but it has to be analyzed in more details, maybe there's more behind it +10:03 < morimoto> OK, thanks +10:05 < pinchartl> next topic, +10:05 < pinchartl> Topic 3. Multimedia plan +10:05 < pinchartl> which is related to +10:05 < pinchartl> Topic 4. Additional tasks for Q2 +10:05 < pinchartl> additional tasks for Q1 are due mid-March +10:05 < pinchartl> so ideally we should already have started negotiating additional tasks for Q2 +10:06 < pinchartl> which isn't the case +10:06 < pinchartl> and it realistically can't be finalized before I leave at the end of this week +10:06 < pinchartl> which means we would need to delay additional tasks once again +10:07 < pinchartl> we have, however, started drafting a plan for multimedia development in Q2 and beyond when we were in Portland +10:08 < pinchartl> with task proposals for Q2 +10:08 < pinchartl> I thus propose trying more losely-defined additional tasks for the first batch of Q2, with the details shifted from the SoW to the overall multimedia + development plan and schedule +10:09 < pinchartl> in practice this means that SoWs could be negotiated faster +10:09 < pinchartl> but the deliverables and milestones will be as clearly defined as before +10:09 < dammsan> sure, we just need a plan =) +10:09 < pinchartl> dammsan: did I send you the spreadsheet we wrote during the meeting ? +10:10 < dammsan> i don't think so +10:10 < pinchartl> I thought I did but couldn't find that in my mailbox +10:10 < pinchartl> ok +10:10 < pinchartl> that's fixed now +10:10 < dammsan> thanks!! +10:11 < neg> if possible I would also like a copy of the portland spreadsheet :-) +10:11 < uli___> same here +10:11 < dammsan> pinchartl: would it be possible for you to extract loose additional tasks for each member from the spread sheet? +10:12 < pinchartl> neg: uli___: done +10:12 < neg> thanks +10:12 < pinchartl> dammsan: the focus is VIN for all team members for the first half of Q2 +10:12 < dammsan> pinchartl: or i can do it if you are busy +10:12 < pinchartl> (except for me I suppose, as VSP and DU still need maintenance) +10:13 < pinchartl> so I propose the same additional task for everybody + +10:13 < pinchartl> so I propose the same additional task for everybody +10:13 < pinchartl> along the lines of "VIN CSI-2 multiple virtual channels development for Gen3" +10:13 < dammsan> ok, so what is the deliverable then? +10:14 < pinchartl> the type of deliverables is still kernel code, tests, documentation, as usual. posted to the same mailing lists and wikis +10:14 < pinchartl> and the exact tasks are then defined in a plan +10:15 < pinchartl> we had +10:15 < pinchartl> ADV7482 Gen3 support upstream +10:15 < pinchartl> MAX9260 driver prototype (Blanche) +10:15 < pinchartl> MAX9271 driver prototype (Camera) +10:15 < pinchartl> MAX9286 driver prototype with a single channel (Gen3) +10:15 < pinchartl> V4L2 multiplexed stream support (.s_stream(), frame descriptors) +10:15 < pinchartl> V4L2 pad-aware async subdev support +10:15 < pinchartl> we need to revisit the details a bit as MAX9260 + Blanche might not make too much sense at this point +10:16 < pinchartl> (as our PCB development plans got cancelled things may need to be adapted) +10:16 < dammsan> sure +10:17 < dammsan> so based on the spread sheet +10:17 < dammsan> it looks like it is possible to deliver a bunch of prototypes for the first batch +10:18 < dammsan> that would be 5/M as due date +10:19 < pinchartl> yes +10:19 < pinchartl> but there are many dependencies +10:19 < pinchartl> so we'll need to adjust the goals dynamically if some parts get delayed +10:20 < pinchartl> the OV10635 + MAX9271 + MAX9286 prototype is very important in that regard +10:20 < pinchartl> uli___: we all count on you :-) +10:20 < uli___> omg... +10:20 < dammsan> so all tasks marked with Q2/1 can be baked into a single task then? +10:20 < pinchartl> that's my proposal +10:21 < pinchartl> same additional task wording for everybody +10:21 < pinchartl> still with clearly defined goals internally, which can be communicated to Renesas +10:21 < dammsan> sure +10:21 < pinchartl> and we'll follow progress at least bi-weekly during the multimedia meetings +10:21 < dammsan> can you communicate this plan with all members? +10:22 < dammsan> so people not present in portland knows whatis going on +10:22 < pinchartl> I would like to add to the SoWs that team members are responsible for reporting any current or foreseen issue or blocker ASAP to make it possible for the + plan to be maintained dynamically +10:22 < pinchartl> let me send the spreadsheet to the periperi list +10:23 < dammsan> so how do we make the task description? +10:23 < pinchartl> or actually I'll attach it to the meeting report +10:23 < dammsan> wait until you're back? +10:23 < pinchartl> do you mean the SoW description or the tasks ? +10:24 < dammsan> i mean the SoW description +10:24 < dammsan> i guess we all want the papers in our hand +10:25 < pinchartl> I would call them something along the line of "VIN CSI-2 multiple virtual channels development for Gen3" +10:25 < pinchartl> all the boilerplate text can be copied from previous SoWs +10:25 < pinchartl> with an additional paragraph asking to report issues and blockers proactively +10:25 < pinchartl> and then a small description of the goal +10:26 < dammsan> okhow about including the list of device drivers? +10:26 < pinchartl> with short-term goals being communicated as part of the multimedia team management +10:26 < pinchartl> yes, I'd include VIN, CSI-2, MAX*, ADV*, ... +10:26 < pinchartl> we should list all of them +10:26 < pinchartl> I can try to send you a draft before I leave +10:26 < dammsan> can we have prototype driver support included as delvierable? +10:27 < pinchartl> yes +10:27 < dammsan> good +10:27 < dammsan> sure, if you can manage before you leave that would be great +10:28 < pinchartl> regarding the work itself and the detailed tasks +10:28 < pinchartl> there's a proposal in the spreadsheet +10:28 < pinchartl> but it will depend on the work Ulrich is doing +10:29 < pinchartl> so we'll still need a few weeks before we can start the work on those external components +10:29 < pinchartl> that's not an issue for Niklas (who will work on the VIN driver itself), Kieran (who will work on ADV7482) or me (who will be away for two weeks anyway) +10:30 < pinchartl> for Jacopo and Ulrich, I think continuing the work on the OV10635 and MAX* is still the next logical step +10:30 < dammsan> sounds good to me +10:31 < pinchartl> jmondi: how long will you still be busy with your current tasks, when will you need new ones ? +10:31 < pinchartl> dammsan: maybe you can help answering that question +10:32 < jmondi> for multimedia only: let's say I can fill this week with test application +10:32 < dammsan> pinchartl: i'm sure jacopo is happy to follow your plan as top priority +10:33 < jmondi> I can buy some time with IO and Core tasks (hopefully some feedback will arrive on both now that 4.12 merge window has closed) +10:33 < jmondi> I can live with what I have been tasked with until the end of March... +10:33 < pinchartl> I'll be back on the 26th of March +10:34 < pinchartl> if you need more work before I come back, there's the OV10635 driver +10:34 < pinchartl> morimoto: I think you mentioned during the Portland meeting that you could get a datasheet (under NDA) for that sensor +10:34 < pinchartl> do you know when we could get it ? +10:34 < jmondi> I can start looking into that, sure... Maybe not deliver that much, but studying it yes +10:35 < jmondi> If my understanding is correct, uli___ has some bsp code I can look at for that driver, right? +10:35 < pinchartl> correct +10:35 < pinchartl> the goal is to turn that into a proper V4L2 subdev driver +10:35 < pinchartl> with the help of the datasheet +10:36 < pinchartl> I think you'll have at least a week of work you can do before having to test anything +10:36 < morimoto> pinchartl: I'm sorry, but which sensor ? +10:36 < pinchartl> OV10635 +10:37 < morimoto> ? you didn't get it from Jinso ? +10:37 < pinchartl> let me verify that +10:37 < pinchartl> I got the schematics of the MAX9286 board +10:37 < pinchartl> and the MAX9286 datasheet +10:37 < pinchartl> the MAX9271 datasheet is publicly available so that's fine +10:38 < pinchartl> but I haven't received the OV10635 datasheet +10:38 < morimoto> OK, will check +10:38 < pinchartl> thank you +10:39 < pinchartl> could you please also provide it to Magnus (through Jinso if needed) ? +10:39 < pinchartl> dammsan: and could you then forward it to Jacopo ? +10:39 < pinchartl> or can Jinso provide it to Jacopo directly ? +10:40 < morimoto> pinchartl: will do +10:41 < pinchartl> thank you +10:42 < pinchartl> I think that's all for the plan/additional tasks topic, unless someone has more questions +10:42 < dammsan> sounds good +10:43 < pinchartl> this actually leaves me without additional tasks ;-) +10:43 < jmondi> I'll sync with uli___ to have that bsp driver shared +10:43 < pinchartl> but I'm ok until end of March this time, so we can negotiate them when I'll be back +10:44 < pinchartl> dammsan: is that ok with you ? do you think we can proceed fast at end of March ? +10:44 < jmondi> and wait for that datasheet to land in my inbox from morimoto or dammsan +10:45 < pinchartl> jmondi: it's here +https://github.com/CogentEmbedded/meta-rcar/blob/v2.12.0/meta-rcar-gen3/recipes-kernel/linux/linux-renesas/0040-H3-MAX9286-TI964-support-add-10635-10640-cameras.patch +10:46 < jmondi> pinchartl: oh, thanks... +10:46 < jmondi> ov10635.h 1159 lines... loving it already +10:46 < neg> :-) +10:46 < pinchartl> and it combines 3 drivers... it's quite messy +10:47 < pinchartl> there's also https://patchwork.linuxtv.org/patch/18768/ +10:47 < dammsan> pinchartl: i'm flexible +10:47 < jmondi> is this saner? +10:48 < pinchartl> jmondi: in the sense that it's a driver for the ov10635 alone, yes. it has to be ported away from soc-camera +10:48 < pinchartl> dammsan: ok, let's do that then +10:49 < pinchartl> morimoto: as I'll propose additional tasks for me at end of this month, please let me know if there's any particular request from the BSP team +10:49 < morimoto> jmondi, you can find ov10635 (local) driver here +10:49 < morimoto> http://git.ti.com/android-sdk/kernel-omap/blobs/eb15176df1e988393d12a2b8c2becd30078edbd8/drivers/media/i2c/ov10635.c +10:50 < pinchartl> it's the same driver. possibly slightly modified though +10:50 < pinchartl> jmondi: you'll have to consolidate all the code available I think +10:50 < morimoto> pinchartl: will do, with Magnus +10:51 < pinchartl> morimoto: thank you +10:51 < pinchartl> there are also base contracts that need to be renewed +10:51 < pinchartl> dammsan: any news about that ? +10:51 < jmondi> morimoto: pinchartl: thanks both... I'll save these and study +10:52 < morimoto> jmondi: worst case, you can create driver without datasheet :) +10:52 < pinchartl> jmondi: thank you. feel free to first focus on your other tasks, I could then be back when you'll start on the ov10635 to answer questions +10:53 < dammsan> pinchart: base tasks are higher priority than additional +10:53 < dammsan> i think they will be similar to before +10:53 < jmondi> morimoto: and if I know OV datasheet a bit, that would not make a big difference. pinchartl: that's the plan, right! +10:54 < pinchartl> dammsan: ok. I don't really expect anything new there indeed, but if you need any information from me, please let me know +10:54 < dammsan> however the "developer" task might go from per-group to a unified description for all groups +10:54 < pinchartl> I'm fine with that +10:54 < dammsan> the group leader tasks will still be separate +10:54 < pinchartl> it's a base contract anyway, it has to be losely defined +10:54 < pinchartl> thanks. I don't want to start leading other groups, we already have leaders who handle that fine :-) +10:55 < pinchartl> jmondi: the OV datasheets are not perfect, but they can still help +10:55 < pinchartl> dammsan: there's also a 25% base contract for Kieran in the pipe, right ? +10:55 < dammsan> i believee so +10:56 < dammsan> need to double check in the renesas office later this week +10:56 < pinchartl> great, thanks +10:57 < pinchartl> next topics then +10:57 < pinchartl> (let's finish this meeting...) +10:57 < pinchartl> Topic 5. Meeting around LinuxCon Japan +10:57 < pinchartl> uli___: could you please provide your availabilities ? +10:58 < uli___> for linuxcon japan? +10:59 < pinchartl> yes +10:59 < pinchartl> see "[periperi] Meeting around LinuxCon Japan" +10:59 < uli___> not available, i'm afraid +11:00 < pinchartl> not at all ? +11:00 < uli___> no, sorry. +11:00 < pinchartl> ok +11:00 < pinchartl> that's a shame +11:01 < pinchartl> but at least you don't have difficult requirements :-) +11:01 < uli___> always happy to help :) +11:01 < pinchartl> then +11:02 < pinchartl> the result is +11:02 < pinchartl> 66-77-788-77-76 +11:02 < pinchartl> (rounded) +11:03 < pinchartl> it's nearly a tie between before LCJ (77) and after (76) +11:04 < pinchartl> I'm tempted to go for 77 in that case +11:04 < pinchartl> but Niklas had a 11 score for that +11:04 < pinchartl> while Kieran and Jacopo have a 43 and 55 score respectively for the two days after the conference +11:05 < pinchartl> neg: how bad would it be for you before LCJ ? +11:05 < neg> managable +11:06 < jmondi> if for Niklas is not that pressing, I would encourage meeting before LCJ :) +11:06 < neg> at this point I'm more focused on setting the date and then I can work around it :-) +11:07 < pinchartl> then I'd rather go for monday-tuesday before the conference, as it has the highest score +11:07 < pinchartl> (nothing personal, it's all 99 for me) +11:08 < neg> works for me +11:08 < pinchartl> thank you +11:08 < pinchartl> then it's settled +11:09 < pinchartl> and I'll propose social events on the weekend after the conference (at least on Saturday) as that's 77 +11:09 < pinchartl> I'll be happy to hang out with anyone during the first or second weekend +11:09 < pinchartl> final topic +11:10 < pinchartl> Topic 6.

And, it could boot correctly. (Magnus-san, Thank you!) +09:21 < shimoda> - The patch sets seem update later, I will make a workaround patch for SDHI after new patch sets are submitted. +09:21 < shimoda> B) +09:21 < shimoda> - After new patch sets of IPMMU are available, I will make a workaround patch. +09:21 < shimoda> C) +09:21 < shimoda> - Nothing for core. +09:21 < shimoda> D) +09:21 < shimoda> - Nothing for core. +09:21 < shimoda> -- EOT -- +09:22 < geertu> shimoda: What does "its own descriptor memory" mean? How does it differ from "Built-in memory"? +09:22 < shimoda> geertu: oops, it mean the same as its own descriptor memory and Built-in memory +09:24 < shimoda> if we would like to use SYS-DMAC0's built-in memory, +09:24 < geertu> shimoda: The documentation for DMADPBASE_n.SEL says "0: Setting Prohibited" +09:25 < geertu> Ah, only for Gen3.

And 0.52 is for H3 ES1.x? +09:36 * geertu sha256sum OK +09:36 < morimoto> My understanding is that 0.51 is for ES1.x, 0.52 and later is for ES2.0 +09:36 < morimoto> shimoda: my understanding is correct ? +09:37 < shimoda> morimoto: yes. +09:38 < geertu> So 0.52 is not useful, as it's superceded for H3 ES2.0 and M3-W ES1.1 by 0.53? +09:39 < geertu> And which one is for H3 ES1.0? rev. 0.20? ;-) +09:40 < morimoto> Actually, 0.52 was updated in these days, and we don't know what happen on it :( +09:41 < morimoto> 1st version to 0.51 was for ES1.x +09:41 < morimoto> If my understanding was correct +09:42 < morimoto> geertu: you question is which is for ES1.0, and which is ES1.x ? +09:42 < morimoto> But in our understanding, datasheet has no difference for ES1.x +09:42 < geertu> morimoto: yes. OK. +09:43 < shimoda> according to the manual team's redmine, rev.0.50 is H3 ES1.1. 0.51 is M3. 0.52 is V3M. 0.53 is V3H. and 0.54 (will be released on end of Apr) is M3N, D3 and E3 +09:44 < geertu> OK, thx +09:45 < geertu> Thank you, Morimoto-san +09:45 < geertu> Next is Magnus +09:49 < dammsan> ok, i've been working on IPMMU and DMAC, nothing else to report =) +09:49 < geertu> Thanks, Magnus +09:49 < geertu> Next is Jacopo +09:50 < jmondi> here I am, so.. +09:50 < jmondi> A) Nothing: no core work since last time we met +09:50 < jmondi> B) I have now received a considerable amount of reviews on RZ/A1 pin controller, I will send v2 possibily this week +09:51 < jmondi> C) not really a task, but I still have to work on Peach, and I'm waiting for digikey to deliver me some stuff +09:51 < jmondi> D) none +09:51 < jmondi> --- eot --- +09:51 < geertu> Thank you, Jacopo +09:52 < geertu> Next is Geert +09:52 < geertu> A) What have I done since last time +09:52 < geertu> - v2 of R-Car H3 ES2.0 support (clk/pfc/sysc) +09:52 < geertu> - v2 of INTC-SYS clock addition +09:52 < geertu> - v2 of R-Car M3-W secondary CPU +09:52 < geertu> - v5 of DMA_ATTR_FORCE_CONTIGUOUS +09:52 < geertu> - DT binding update to add resets to rcar-du +09:52 < geertu> - DT binding and identification of RZ/G1H and RZ/G1N +09:52 < geertu> - Posted "long story" summary for Suspend-to-Idle to periperi +09:52 < geertu> - DT cleanups +09:52 < geertu> B) What I plan to do till next time +09:52 < geertu> - v2 of resets for R-Car H3 and M3-W DTS +09:52 < geertu> C) Problems I have currently +09:52 < geertu> - None +09:52 < geertu> D) Posted/Accepted bugfix patches +09:52 < geertu> - Nothing important +09:52 < geertu> EOT +09:53 < geertu> laurent and Marek are excused, Ulrich and Simon are absent, so no updates from them +09:53 < geertu> Topic 2.

One to + Salvator-X and one to the Camera board and as long as you already have + two Gen2/Gen3 power cables you are ok +<morimoto> neg: Yes +<morimoto> 1 note is that camera board doesn't have reset button [16:55] +<morimoto> You need to plug out/in for reset camera board :P +<morimoto> I think above url has such explanation +<pinchartl> do you know if the salvator-x and camera boards can be powered up + in any order, or is a specific order required to avoid damaging + the hardware ? [16:56] +<morimoto> Yes, it has special order. you can check it on above URL +<morimoto> see.

[17:11] +<jmondi> few things to report since last time +<jmondi> I only spent 1 week of my time on multimedia, and I have ported the + DRM/KMS test application to gen 3 +<jmondi> not tested with VIN patches yet +<jmondi> but I have closed pinchartl review comments on last version [17:12] +<jmondi> I should send out an email with details probably... +<pinchartl> that would be nice +<jmondi> apart from that not much, still waiting to have a more defined plan + for next months, where I should be all about multimedia +<pinchartl> thank you [17:13] +<jmondi> I guess the OV datasheet export issue has impact on me, as I was + supposed to work on ov10(don't remember name) sensor, right? +<pinchartl> correct [17:14] +<pinchartl> morimoto: maybe the datasheet should appear magically on a server + somewhere +<pinchartl> nobody will know where it came from [17:15] +<pinchartl> and nobody will ask any question +<jmondi> for just a few minutes maybe? +<pinchartl> life will be good, everybody will be happy +<morimoto> pinchartl: actually, it will takes long term for export [17:16] +<morimoto> but, I can put it on Redmine if I can be guilty guy [17:17] +<pinchartl> nobody will tell :-) +<morimoto> Hehe :) +<morimoto> jmondi: when do you need it ? immediately ? [17:18] +<jmondi> morimoto: the sooner the better +<morimoto> OK... +<jmondi> since we're both online, you can upload and delete in 5 minutes +<morimoto> Please pray that no stone-head guys come here :) +<pinchartl> there's usually an application note that goes with the OV sensors + datasheets +<pinchartl> if you have to too, it would be nice to get it +<morimoto> It will be formal, but not yet now +* kbingham grabbed a copy to see too :) [17:22] +<pinchartl> no problem +<morimoto> I only have datasheets, not application note +<pinchartl> that closes the first topic +<pinchartl> Topic 2. Multimedia plan +<morimoto> If you need it, I can ask to OmniVision guy +<pinchartl> dammsan: what's the status of base contracts and additional tasks + for Q2 ? +<pinchartl> morimoto: it would be nice to get it, the datasheet usually lacks + important information that is present in the application note +<morimoto> pinchartl: OK, will do [17:23] +<morimoto> neg: I will delete datasheet, are you OK ? +<neg> yes [17:24] +<neg> thanks, and what datasheet :-) +<dammsan> pinchartl: the base tasks have been submitted, waiting for + processing [17:25] +<dammsan> additional tasks +<pinchartl> do you expect any issue or delay for the base tasks ? +<dammsan> not really +<dammsan> i think the only unknown is that camera prototype at this point +* morimoto bye-bye datasheet [17:26] +<dammsan> i expect base tasks to be ready this week +<pinchartl> ok +<pinchartl> how about the additional tasks ? [17:27] +<dammsan> i think your idea with the shared more generic task description is + good +<dammsan> so i would like to proceed with that [17:28] +<dammsan> however, i would like to know that we at least have _something_ that + works first +<pinchartl> uli___: I think there's a bit of pressure on you :-) [17:29] +<dammsan> from my side, we can be blocked on several other random issues + before we get there +<pinchartl> but in any case we have to go in that direction +<dammsan> (who knows, another power supply needed or perhaps some jumper is + missing) +<pinchartl> which is why I want more generic tasks [17:30] +<pinchartl> to handle the issues as we progress +<dammsan> sure +<dammsan> i mainly want results myself =) +<pinchartl> have you submitted the generic task proposal internally to Renesas + to get their feedback ? [17:31] +<dammsan> nope +<dammsan> we've been busy with base tasks +<pinchartl> Q2 starts next week, and I think everybody is getting nervous + [17:32] +<dammsan> this is why we have the base tasks +<dammsan> i would have preferred to have overlapping ones myself +<dammsan> but hey +<pinchartl> how would you like to proceed ? +<dammsan> i want to get the updated result from the camera prototype [17:33] +<dammsan> i propose that we revisit next week, hopefully some update is + available then? +<dammsan> that should have sorted out the base tasks too +<pinchartl> ok [17:34] +<pinchartl> by the way +<pinchartl> morimoto: what's the status about the hardware setup that should + be sent to Europe ? [17:35] +<dammsan> in the mean time, lets do ping-pong-email you and me in case some + detail need to be adjusted in the additional task descripiton +<morimoto> pinchartl: camera board ? [17:36] +<pinchartl> morimoto: yes [17:37] +<morimoto> camera *board* I already have +<morimoto> camera itself will be arrive at 5 +<morimoto> 5 = May +<pinchartl> at 5 ? 5pm today ? :-) +<pinchartl> ok +<uli___> 5pm in may +<pinchartl> when in May ? +<morimoto> Hehe +<morimoto> Don't know, just "May" [17:38] +<pinchartl> so potentially we won't have access to local hardware before end + of May ? +<morimoto> Unfortunately +<jmondi> we can pick them at LCJ directly :/ [17:39] +<pinchartl> ok +<morimoto> jmondi: Unfortunately, it is not allowed +<pinchartl> that's not very nice, but we have no choice +<pinchartl> how comes the camera will arrive so late ? is it because of the + lead time from the manufacturer ? +<morimoto> I'm not sure, I know is that it will came from Philippine [17:40] +<pinchartl> who's the manufacturer ? do you have a model number ? [17:41] +<morimoto> Module name is "RDACM20-01" [17:42] +<pinchartl> thank you +<morimoto> manufacturer seems... IMI Japan [17:43] +<pinchartl> I don't think it makes sense to really update the multimedia plan + at this point before we have results from Ulrich's work + [17:45] +<pinchartl> uli___: is there any way we can help to speed it up ? +<uli___> during this meeting i have received an e-mail from my tax guy, who + has failed to do my taxes for 2015, which are at the absolute latest + due tomorrow, until now [17:46] +<uli___> i need to look up some documents +<geertu> http://www.global-imi.com/about-imi/global-facilities/ does not list + Japan. But it does list Czech Republic and Bulgaria +<uli___> i'm afraid that has 110% priority +<uli___> i'll still try to do the test today, though +<pinchartl> uli___: let's discuss the results tomorrow morning then [17:47] +<uli___> ok +<pinchartl> Topic 3. Meeting around LinuxCon Japan [17:48] +<pinchartl> we have agreed on dates for the trip [17:49] +<pinchartl> with a VIN code camp with local hardware access on the 29th and + 30th of May +<pinchartl> so far no meeting with the BSP team is scheduled, as no need to + have such a meeting has been expressed [17:50] +<pinchartl> morimoto: dammsan: does that still hold ? or do you think we + should organize a meeting ? +<morimoto> pinchartl: no plan with BSP team meeting at this point. [17:51] +<dammsan> pincharl: we should go out for drinks together at least =) [17:52] +<pinchartl> dammsan: of course :-) +<pinchartl> I'd like to spend as much time coding as possible [17:53] +<pinchartl> so if meetings are needed, I'd like to know ASAP +<dammsan> makes sense +<neg> I would also like to book my trip soonish :-) +* jmondi too ^ [17:54] +<kbingham> Yes, flights have increased in price by 30% already here I think. +<kbingham> (google keeps telling me when the price changes) +<kbingham> Of course that could just be because the £ has decreased in value + :) [17:55] +<neg> I think I managed to clear my previous date troubles so I should be + avaliable from/to both weekends before and after and be happy to stay + both if other ppl are around for code or drinking sessions ;-) +<pinchartl> neg: \o/ +<jmondi> neg: you're talking about the May 27th/28th weekend and June 3rd/4th, + right? [17:56] +<pinchartl> morimoto: persmission to book flights then ? +<kbingham> I can do before much easier than after :) [17:57] +<neg> jmondi: yes +<morimoto> pinchartl: sorry, what do you mean? +<pinchartl> morimoto: can we go ahead and book flights for the week in Japan ? + and can we invoice them to Jinso ? [17:58] +<morimoto> Ahh, OK. I will ask to our boss, please wait +<pinchartl> thank you [18:00] +<pinchartl> last topic, next meeting +<pinchartl> I propose two weeks from now [18:01] +<pinchartl> Tuesday the 11th of April +<jmondi> works for me I guess +<pinchartl> at 8:00 GMT / 09:00 CEST / 10:00 EEST / 16:00 JST +<pinchartl> (usual time) +<dammsan> sounds good +<kbingham> Ack here. [18:02] +<pinchartl> good, I'll send the invite now +<morimoto> pinchartl: how many people caming to Japan ? +<pinchartl> morimoto: Ulrich can't make it, so that would be Jacopo, Kieran, + Niklas and me +<morimoto> And Core/IO group member ? [18:03] +<neg> date works for me +<geertu> pinchartl: You really want to conflict with all future Core Meetings? +<pinchartl> morimoto: I don't know about Gert or Wolfram's plans for LCJ +<pinchartl> geertu: good point +<pinchartl> should we make it Wednesday the 12th ? +<geertu> pinchartl: What happened with the MM meetings on Wednesdays? +<pinchartl> geertu: lack of sleep I think :-) [18:04] +<pinchartl> we've switched this week, but let's go back to the original + schedule +<pinchartl> so Wednesday the 12th +<pinchartl> at 8:00 GMT / 09:00 CEST / 10:00 EEST / 16:00 JST +<dammsan> gotcha [18:05] +<pinchartl> I propose closing this meeting +<pinchartl> does anyone second? +<geertu> pinchartl: Thank you! +<morimoto> pinchartl: about trip budget, maybe OK +<pinchartl> geertu: you're welcome +<morimoto> pinchartl: about 4/12 2nd [18:06] +<pinchartl> 4/12 2nd ? +<morimoto> s/2nd/second/ +<morimoto> I mean OK for 4/12 meeting [18:07] +<pinchartl> :-) +<kbingham> 4th December is a bit late :D +<pinchartl> perfect +<pinchartl> thank you all for attending +<pinchartl> and have a nice day +<kbingham> Cheers all +<neg> thanks all +<morimoto> kbingham: oops, 4/12 = 4th December in Europe, it is April, 12th in + Japan ;P [18:08] +<jmondi> cheers! see you +<morimoto> thanks diff --git a/wiki/Chat_log/20170329-core-chatlog b/wiki/Chat_log/20170329-core-chatlog new file mode 100644 index 0000000..154230e --- /dev/null +++ b/wiki/Chat_log/20170329-core-chatlog @@ -0,0 +1,362 @@ +Core-chat-meeting-2017-03-29 + +10:07 < geertu> Welcome to today's Core Group Chat! +10:07 < geertu> Agenda: +10:07 < geertu> 1.

PFC drivers for RZ/G1 +10:23 < geertu> Cogent (Sergei) is preparing the upstreaming of the PFC drivers for r8a7743 +10:23 < geertu> (RZ/G1M) and r8a7745 (RZ/G1E). +10:23 < geertu> To avoid adding and maintaining 20 kLoC of new pinctrl code, I would like +10:23 < geertu> to reuse the existing drivers for R-Car M2-W and E2. +10:23 < geertu> While RZ/G1 supports less hardware than R-Car Gen2, my point is that if a +10:23 < geertu> device does not exist in r8a7743.dtsi or r8a7745.dtsi, you won't set up +10:23 < geertu> pinctrl for pins/groups/functions for that device, and thus won't use +10:23 < geertu> nonexisting PFC enums. +10:23 < dammsan> makes complete sense +10:23 < geertu> Sergei wants to make sure that adding further support for non-existing +10:23 < geertu> devices won't be possible, and thus wants to have separate drivers. +10:24 < dammsan> as opposed to +10:24 < geertu> Lately, it seems Sergei is becoming convinced. +10:25 < geertu> But perhaps only because I (wearing my sh-pfc hat) have to accept his patches... +10:25 < geertu> Unfortunately, he has less (different) information than we have, cfr. his resistance. +10:26 < geertu> It may be easier if we can share some information with him. +10:26 < dammsan> this different information, i wonder if we can work on that to improve things +10:27 < dammsan> of course sharing info would be nice, but i don't see how that will happen with the different ordering schemes and NDAs and whatnot +10:28 < dammsan> what is he missing? +10:28 < dammsan> (apart from the obvious =) =) =) +10:29 < geertu> However, a nice side-effect of his uninformedness is that he's rigorously comparing r8a7743 and r8a7791 PFC, and discovering bugs in pfc-r8a7791.c +10:29 < dammsan> well that is good +10:31 < dammsan> i think that trying to validate the DT from within a driver is not a very good approach +10:31 < dammsan> basic integration assumes that you input the right stuff into DTS including address ranges, interrupts and of course also pins +10:32 < dammsan> seems that he prefers to do some validation somehow, or perhaps i misunderstand +10:33 < geertu> dammsan: I think the only extra validation he can gain from using a separate driver is the ability to reject pin groups for on-SoC devices that are not documented in the RZ/G1 datasheet. +10:33 < horms> surely the dt describes the hardware and the driver implements some set of features which may overlap with what is described in dt +10:35 < geertu> dammsan: For a specific on-SoC device, I think the pins, groups, and functions will be the same. +10:35 < dammsan> i guess not duplicating information makes sense for sure +10:35 < dammsan> so not duplicating PFC information in different files must be correct +10:35 < geertu> Sure. +10:36 < dammsan> however one question is if the existing PFC code shall take SoC compat string into consideration and reject invalid stuff somehow +10:36 < dammsan> using the same kind of table +10:36 < geertu> It's just a bit difficult to explain the sharing to people not aware of the details. +10:36 < dammsan> yeah i understand +10:37 < dammsan> if it is useful then it seems like a per-soc feature flag or something +10:37 < geertu> That's definitely a possibility. But what would be the gain? It's not like people are gonna configure pinctrl for a function that has no corresponding device name in the SoC-specific dtsi +10:37 < dammsan> horms: can you explain about the overlap in driver vs DT in more detail? +10:37 < geertu> s/device name/devcie node/ +10:38 < dammsan> geertu: i agree +10:38 < geertu> s/device name/device node/ +10:38 < dammsan> if someone copy-pastes DTS wrong and it enables the wrong PFC combo then so be it +10:38 < dammsan> it is like assigning wrong IRQ number in DTS +10:39 < dammsan> simply dont do that +10:39 < horms> I meant; DT could conceivably ask for features that are not yet implemented in the driver (maybe not). And the driver can implement features not used on a particular bit of hw - in which case DT shouldn't ask for them. +10:39 < Marex> indeed, DT is not kindergarten ... +10:39 < horms> copy paste is a big problem for DT; its almost like the system is broken by design +10:40 < Marex> horms: the system is OK, uninformed integrators are the problem here and that cannot really be easily fixed +10:40 < horms> sure, but it is easy to make misakes +10:40 < horms> regardless, i don't think its the role of the driver to verify dt +10:40 < Marex> +1 +10:40 -!- morimoto [~user@relprex1.renesas.com] has joined #periperi +10:41 < dammsan> in most cases the driver cant even judge right from wrong +10:41 < dammsan> and spending extra cycles doing so seems stupid +10:41 < geertu> horms: It's not, but in this case (PFC), the pin group/function names are technically part of the binding. +10:41 < horms> I guess one risk is that someone might enable something on RZ/G1, which is documented not to exist but is implemented in the driver for R-Car, and then discover it does exist on RX/G1 +10:42 < horms> perhaps this is where Sergei's concern lies +10:42 < horms> I imagine that would conflict with Renesas's marketing goals +10:42 < horms> geertu: ok, i had missed that point +10:42 < neg> One drawback if it's shared is that the debugfs interface will show pins/groups that or not valid for the SoC in question +10:42 < geertu> horms: That someone has to add something to r8a774[34].dtsi first, too +10:43 < horms> sure, but that wouldn't be a problem from a maketing pov +10:43 < horms> anyway, its a non-technical reason +10:43 < geertu> neg: True, hadn't thought about debugfs +10:44 < dammsan> having a list of pin functions available together with compat string matching can't be that difficult +10:44 < dammsan> sergei might even be able to implement it himself +10:45 < geertu> neg: That would be limited to the pinmux_groups[] and pinmux_functions[] arrays +10:45 < dammsan> if he feels strongly about it +10:46 < dammsan> i wonder if the relationship beween M2 and RZ-G is similar to H3 ES2 and M3? +10:46 < horms> it could even be done in parallel with other tasks he may have +10:46 < horms> as i wouldn't think it blocks forward progress +10:46 < geertu> neg: we could sort it (common entries first, RZ/G1 entries last), and change sh_pfc_soc_info.nr_{groups,functions} based on compatible value. +10:46 < dammsan> especially since it goes backwards =) +10:47 < dammsan> horms: jokes aside i agree with you +10:47 < horms> we could ask him to implement it sideways :) +10:47 * geertu may be thinking too much about kernel size +10:47 < horms> I wondered about that too +10:48 < neg> geertu: yes that would work, is the pinmux_pins arrays equal on both SoC ? +10:48 < geertu> neg: I expect it is, both SoCs have the same package and nr. of pins, according to the Renesas website +10:49 < neg> that is good, then yes having some magic for the pinmux_groups[] and pinmux_functions[] would then take care of the debugfs issue +10:51 < geertu> Having separate pinmux_groups[] and pinmux_functions[] arrays would waste ca. 6 KiB +10:51 < geertu> so runtime patching may be worth it. +10:56 < geertu> We could also #ifdef out the various *_pins[] and *_groups[] on kernels not including support for r8a7791. +10:56 < dammsan> geertu: i wonder if the package type may limit exposed pins too on G1M compared to M2-W +10:56 < geertu> dammsan: renesas.com says they have the same package +10:59 < geertu> M2-W: 831 pin Flip Chip BGA (27 mm × 27 mm) +10:59 < dammsan> ok then i'm silent =) +10:59 < geertu> G1M: 831 HBGA (I'm quite sure that used to say Flip Chip BGA, too) +11:00 < geertu> E2: 501-pin Flip Chip BGA (21 mm × 21 mm) +11:00 < geertu> G1E: 501 HBGA +11:01 < dammsan> ok thanks! +11:02 < geertu> OK, I'll ask Sergei to use a separate sh_pfc_soc_info with different pinmux_groups/pinmux_functions +11:02 < neg> Did we not use to have runtime patching for Gen3 ES versions previusly? But now that I look in renesas-drivers I can't find it. In any case is that not something we can reuse? +11:02 < geertu> We have the infrastructure in place for handling that for H3 ES2 +11:02 < geertu> neg: Just the .init() callback to override something +11:03 < geertu> neg: patches of the tables is done for clk and rcar-sysc only. +11:03 < neg> I see +11:07 < geertu> Shall we continue? +11:08 < geertu> Topic 3. Additional tasks for 2017/Q2 phase 1 +11:08 < geertu> So far I have: +11:08 < geertu> Gen2,?,plan,geert,Migrate R-Car Gen2 to CPG/MSSR +11:08 < geertu> generic,?,plan,geert,DTS sharing on H3 ES1.x/ES2.0, Salvator-X/ULCB +11:08 < geertu> RCAR-DMAC,?,plan,niklas,Add transfer termination synchronization +11:08 < geertu> Salvator-X,?,plan,marek,BD9571 PMIC driver +11:08 < geertu> It would be good if someone could take over from Khiem: +11:08 < geertu> CPUFreq,v4.12,public,khiem,R-Car Gen3 CPUFreq support +11:08 < horms> I would be happy to look into that if there are no other takers +11:08 < geertu> Patches for that are pubic (with some comments), and in the BSP +11:09 < geertu> Once the PMIC driver is there, we can start doing DVFS +11:09 < geertu> Jacopo worked on the monitoring part using max9611 +11:09 < geertu> So perhaps he's interested as well? +11:09 < wsa_> simon: do you also have room then for the SDHI DMA refactoring task? +11:10 < wsa_> and interest? :) +11:10 < jmondi> geertu: I am :) +11:11 < neg> If horms have too much IO work I can also look at Khiems CPUFreq work +11:11 < Marex> geertu: so what do we do with the PMIC ? And what about the VC6 ? :) +11:12 < horms> Perhaps if I took the SDHI DMA refactoring task and neg could take CPUFreq? +11:13 < wsa_> neg: speaking of IO, there are also "emergency shutdown" and "WakeOnLan for Gen3" tasks for which you have some previous attachment ;) +11:13 < geertu> Marex: I thought you were going to take care of the PMIC, cfr. above? :-) +11:13 < wsa_> neg: but if you are busy, they might be interesting for Jacopo as well? +11:13 < geertu> Marex: VC6 will have to wait for board availability, as the board is expected to arrive before Digi-Key has VC6 devboard stock +11:14 < pinchartl> geertu: if I may, I'd like to discuss how to allocate developers to tasks across groups in a better way than "first group leader who asks will get developers" +11:14 < neg> wsa_: Yes I was hopping to do 'emergency shutdown' for IO sometime during Q2 but WoL for Gen3 is also a possibility +11:14 < pinchartl> there's lots of work to be done on multimedia, and I'm sure core and I/O are nont different from that point of view +11:15 < pinchartl> I could just chime in and say that I need Niklas and Jacopo full time, but that wouldn't be very nice to you :-) +11:15 < pinchartl> so how can we do better ? +11:15 < dammsan> pinchartl: +11:16 < geertu> Ah, the load balancer among groups has arrived ;-) +11:16 < dammsan> i think you may have the most complex dependencies +11:17 < Marex> geertu: got it +11:17 < pinchartl> dammsan: possibly (although I don't want to make it a contest :-)) +11:17 < Marex> geertu: sorry, got a little stuck discussing how to fix jmondi's peach +11:17 < dammsan> noneed =) +11:17 < pinchartl> dammsan: so how can we proceed ? +11:18 < pinchartl> I can't plan anything ahead if at the last minute I have to do with half of the developers I thought could work on multimedia +11:18 < dammsan> in case we have some super emergency in some group we nee +11:18 < pinchartl> so I need a way to plan ahead +11:18 < dammsan> d to allocate based on that +11:18 < geertu> pinchartl: So we need to increase base allocation? +11:18 < pinchartl> you told me yesterday during the multimedia meeting that you wanted to wait before assigning additional tasks for the multimedia group +11:18 < pinchartl> so core and I/O will come first +11:19 < pinchartl> and I'll be left without anyone +11:19 < dammsan> however, i would like to decide based on how each guy +11:19 < dammsan> prefers to work really +11:19 < dammsan> pinchartl: i don't think anyone will steal all the developers +11:19 < pinchartl> if you want me to plan ahead and stick to the plan, I need to know in advance who will be available +11:19 < dammsan> but without working hardware platform it is kind of hard to start a big project +11:19 < wsa_> pinchartl: for me, it is not about "coming first". My picture of the meeting today is that we are all here and discuss how to proceed +11:19 < geertu> marex: 800-3138-ND stil has 18 weeks lead time, 12/6/2016 - Delivery Date Past Due - Contact Digi-Key +11:20 < dammsan> right +11:20 < pinchartl> wsa_: the issue is that we allocate tasks seperately for each group +11:20 < Marex> geertu: yeah :( +11:20 < dammsan> so i would like each developer to join at least two groups +11:21 < dammsan> and in a perfect world i think additional tasks from two groups should be handled +11:21 < geertu> Marex: Buy a 5P49V6901A and put it on a protoboard? +11:21 < wsa_> pinchartl: my hope is that today we will do it differently +11:21 < pinchartl> dammsan: we're talking about half a quarter of additional tasks, so that's 60 / 2 / 2 = 15 days +11:21 < pinchartl> joining two groups seems quite dubious to me with such a short amount of time +11:22 < dammsan> pinchartl: it is possible to assign more than one batch of work too +11:22 < wsa_> one problem is, I don't know priorities from other groups, so I'd like to know about those as well +11:22 < dammsan> it depends on the kind of task +11:22 < dammsan> neg: how would you like to spend your time? =) +11:22 < wsa_> I mainly threw in the topics I have, so people know what is around +11:22 < Marex> geertu: well I can immediatelly get me a 6901 in a VFQFPN +11:22 < wsa_> I'd prefer if we can agree on priorities together +11:22 < pinchartl> 5 days tasks really don't make sense in most cases. the scheduling overhead is too large +11:22 < Marex> geertu: I guess I could wirebond it to a breadboard ... +11:22 < pinchartl> wsa_: I agree +11:23 < neg> dammsan: I would like to help as much as possible where the need is greatest. But I also like to if possible have tasks from two groups +11:23 < pinchartl> that would require a whole team meeting though +11:23 < dammsan> neg: so in case more work is needed for multimedia then perhaps allocating mroe slots there makes sense +11:24 < Marex> geertu: problem might be the external components ^_^' +11:24 < neg> dammsan: I also have quiet a lot of base-task time in April which currently is not fully allocated to tasks so I can do some tasks in that timeframe +11:24 < dammsan> makes sense +11:25 < dammsan> so the number of Core and I/O tasks are that not many, are they? +11:25 < wsa_> neg: how about doing "emergency shutdown" as a base task then? +11:25 < wsa_> neg: as I understood, you'd like to do that, and from my side it has not the highes priority +11:26 < neg> wsa_: sounds good to me, but if it's not high prio I can do something else as part of my base. Only problem is that IO is not listed as a group I should do work for in my base contract ATM +11:27 < dammsan> geertu: do you have some tasks that will cause delays for everyone if they are not executed before other groups? +11:27 < dammsan> PFC/CPG/SYSC something +11:28 < dammsan> i think not +11:28 < geertu> dammsan: I don't think I have any urgent core tasks +11:28 < neg> One crazy idea is to allocate more base contract time to multimeda tasks since there are so many dependecies there to provied flexability and do less complex tasks as additional contracts? +11:28 < dammsan> neg: whatever rocks your boat +11:28 < geertu> So "additional" is for the already-known tasks, and "base +11:28 < geertu> " for the unexpected ;-) +11:29 < pinchartl> neg: the proposal for multimedia additional tasks is already quite generic, so it's not very different from the base contract in that regard +11:29 < dammsan> geertu: ok, nothing urgent +11:29 < pinchartl> if we want detailed additional tasks, at this point of time I'd prefer using them for core or I/O +11:29 < pinchartl> I personally don't care in which report a patch will be included +11:30 < pinchartl> my concern is getting the work done in time +11:30 < dammsan> pinchartl: totally agree +11:31 < dammsan> neg: so how about assigning one slot of additional task per group per quarter? and base goes mainly to multimedia? +11:32 < neg> works for me. most setups works for me, as long as everyone is happy so am I +11:32 < dammsan> just a random proposal +11:32 < pinchartl> dammsan: personally I wouldn't agree to have a 5 days additional multimedia task as it would become too painful from a report overhead point of view, but if people want to bother, I don't care +11:32 < pinchartl> (good luck coming up with deliverables that jinzai could test though) +11:32 < dammsan> pinchartl: doesn't it depend on what kaind of task? +11:33 < dammsan> say a prototype to get that V2H camera going? +11:33 < pinchartl> dammsan: generally speaking it does, but with the tasks we have now, there's nothing suitable for 5 days +11:33 < dammsan> you can achieve a lot with 5 days +11:33 < pinchartl> you can write a report in 5 days, yes +11:34 < dammsan> perhaps it is possible to reduce the complexity of the reporting =) +11:34 < pinchartl> with a 5 days task I personally allocate at least 20% of the time to the report +11:34 < pinchartl> that's way too much +11:34 < dammsan> i agree +11:34 < pinchartl> (and with the time I spend negotiating the task descriptions with you, it goes to 30%) +11:34 < dammsan> if it takes more than one hour then something i wrong IMO +11:34 < dammsan> pinchartl: the task negotiation time is part of your base task as group leader +11:34 < pinchartl> beside, jinzai is pretty much useless when testing deliverables +11:35 < pinchartl> so it's really wasted time +11:35 < dammsan> it depends on what kind of task it is +11:35 < dammsan> no need to make it more complex than it has to be +11:35 < pinchartl> we've been making things more and more complex over time for the past 12 months ;-) +11:35 < dammsan> so lets try to make it easier to move +11:36 < wsa_> same here with 20%, an actually useful elinux page needs time +11:36 < dammsan> i feel this might be the case mainly for multimedia +11:36 < wsa_> they are not bad, though, but they do need time +11:36 < dammsan> wsa_: i didn't mean to include the wiki in that reporting time +11:36 < dammsan> not all tasks require wiki edit +11:36 < dammsan> some do +11:37 < dammsan> it is up to discussion when we make the tasks +11:37 < wsa_> i see +11:37 < dammsan> i was mainly counting time for the PDF report to jinzai +11:37 < pinchartl> dammsan: my concern isn't so much about time needed to write documentation or reports. it's roughly a fixed amount of time. with a 15 days task, the overhead is acceptable. with a 5 days task, it isn't +11:37 < dammsan> ok if you say so +11:38 < dammsan> last time i got a contiguous 5 days to work on something was a loong time ago +11:38 < dammsan> so i feel it would be a great luxury +11:38 < pinchartl> see, that's the problem :-) +11:38 < dammsan> but it is perhaps just me +11:38 < pinchartl> we have too much scheduling overhead +11:38 < pinchartl> no, it's not just you +11:39 < dammsan> ok that's good to know =) +11:39 < dammsan> so i wonder what the other members think? +11:39 < dammsan> especially the group leaders +11:40 < horms> fwiw, I agree there tends to be quite a lot of reporting overhead for extra tasks, especially 5 day ones +11:40 < dammsan> horms: even if you exclude wiki and testing? +11:40 < wsa_> when speaking about the tasks themselves, i assume IO tasks are better suited to 5 days contracts +11:40 < geertu> testing needs to be done. +11:40 < geertu> wiki can be useful (depending on the task) +11:40 < horms> dammsan: not if excluded wiki and testing +11:41 < dammsan> horms: right then we agree i think +11:41 < dammsan> so if we need wiki and testing included then 5 days is pushing it +11:41 < pinchartl> dammsan: don't forget to include babysitting jinzai in the overhead :-) +11:41 < pinchartl> I don't know if it happens to the other groups too +11:42 < dammsan> pinchartl: the multimedia group has the most complex dependencies and most code not-yet-upstream +11:42 < wsa_> plain reporting (excluding wiki and testing) is OK +11:42 < wsa_> it's the testing and documentation which fragments the 5 days tasks for me +11:42 < dammsan> so allocate two slots if testing and wiki is needed +11:43 < dammsan> end of story =) +11:43 < wsa_> aye aye, sir +11:43 < geertu> Sorry, guys, I have to go. +11:43 < geertu> Shall we conclude the official meeting? +11:43 < dammsan> i still think that there is plenty to do with 5 days in case you do some feature or protoype without additional documentation and testing +11:43 < dammsan> sure +11:44 < geertu> For next meeting, I propose Tuesday, April 11, same time +11:44 < jmondi> I have to leave in ~20 mins as well... I would like to write down what's my contract situation for next quarter, so group leaders know what I can do and when..

If those could be tested on more boards then my Koelsch I think we could (re)try to get them picked up in upstream OpenOCD. Do you think there would be value in this? +10:28 < neg> I posted the configs at https://git.ragnatech.se/renesas-jtag/ and intend to write up elinux wiki page, I assume the SW settings to enable JTAG are OK to describe there as well? +10:30 < geertu> Cool! +10:30 < geertu> I only have +10:30 < geertu> source [find interface/ftdi/flyswatter2.cfg] +10:30 < geertu> reset_config trst_and_srst +10:30 < geertu> jtag_rclk 8 +10:30 < neg> last question is aimed at Morimoto-san :-) +10:30 < geertu> (most from Magnus, IIRC) so I never got that far... +10:31 < jmondi> neg: I will send you patches to use OpenOCD+Flyswatter on RZ as well :) +10:32 < neg> jmondi: nice :-) +10:35 < kbingham> neg: I guess you haven't looked at G3 yet :) +10:36 < neg> kbingham: thats right :-) +10:36 * geertu assumes kbingham is not talking about SH7367 (SH-Mobile G3) +10:37 < kbingham> geertu: Well, maybe I was ... :D +10:37 < geertu> Every spelling mistake is a different SoC ;-) +10:37 * morimoto geertu solved my confusion +10:37 < geertu> morimoto: cs2000? +10:37 < morimoto> No, about G3 :) +10:37 * kbingham coughs : Gen 3 +10:37 < geertu> kbingham: R-Car Gen3? +10:39 * morimoto I think neg's "last question" is not yet coming ? +10:39 < neg> morimoto: sry, my question was if it's OK to mention wich SW on the board you need to flip to enable JTAG, is this OK to mention on the elinux wiki? +10:40 < neg> for Gen2 that is +10:40 < morimoto> Ahh, OK. I think it is no problem +10:41 < neg> OK thanks +10:42 < neg> So I will let them stew in the reop and write a elinux page.

Upstream V4L2 development +<pinchartl> anything else ? +<pinchartl> ok, let's start with status updates [16:03] +<jmondi> maybe a check up on travel plans for OSS? +<pinchartl> jmondi: good point +<neg> Stamp of approvel for Tokyo dates, the mail thread is dead and time to + buy tickets ;-) +<kbingham> Ack with those :) ^ +<pinchartl> Kieran has to run away in the middle of the meeting, so he will + get started +<pinchartl> kbingham: the stage is yours +<kbingham> Why thankyou maestro :-) +* morimoto back [16:04] +<kbingham> So I'm now back on RCar developments and I've commenced looking at + the ADV7482 work +<kbingham> I have had some difficulty capturing frames through VIN so far, + getting the links set up to capture. +<morimoto> neg: we have no W/A at this point, so, nothing to discuss today. it + is just information sharing [16:05] +<kbingham> (I have tried to capture using the existing code base, using HDMI + in ) - and a RPi to generate HDMI data +<kbingham> But the issue is getting the formats to propogate - checking the + formats shows 'unknown' in the FMT field .. and things aren't + propogating through media ctl. [16:06] +<pinchartl> kbingham: do you have further things to try, or are you completely + blocked ? +<pinchartl> if it's a format propagation issue I assume you can try to debug + it +<kbingham> I'll have more things to try - like getting some prints in to see + why the formats aren't there [16:07] +<kbingham> yes - It's just a debug issue really. +<kbingham> But will help me walk the code base anyway +<pinchartl> ok +<neg> kbingham: did you try h3-compliance.sh from vin-tests? +<kbingham> neg: Yup ! Same issue +<kbingham> neg: And I set my RPi dev to 640x480 as you suggested - still no + avail - so I just need to dig and understand the issue +<neg> hum that is strange, guess I need to buy a RPI today :-) +<kbingham> If needed, I'll talk to (neg) later about that if possible. [16:08] +<pinchartl> you can also ask me +<pinchartl> not that I have tried it +<pinchartl> but I can guide you through the format propagation process and + code +<kbingham> pinchartl: Thankyou :D Anyway - otherwise- Once that issue is + resolved, I have started looking at how to create the subdevs, as + per our disucussions +<kbingham> and once I have established a baseline - I should be comfortable + hacking away at that. [16:09] +<pinchartl> ok, thank you +<neg> first guess is it's EDID related since the ADV7482 have no EDID support + I do all my testing using a Xbox as source so I assume it fallback to + something the ADV7482 likes +<neg> that is the ADV7482 driver have no EDID support +<kbingham> By default, the source is coming up as [fmt:unknown/1920x1080 + field:none] [16:10] +<kbingham> Anyway, we can go through that later :D [16:11] +<neg> kbingham: the ADV7482 prototype should autodetect the formats, I would + like to see the fill media graphyou get if possible, but maybe you and I + can hash this out after the meeting :-) +<pinchartl> jmondi: you're next in resumed alpbabetical order :-) +<kbingham> I agree - we'll go through this after the meeting rather than in + the meeting :) +<jmondi> fine... [16:12] +<jmondi> so, I started looking at moving the CEU driver away from soc_camera +<jmondi> I'm still evaluating if it is better to rewrite it or patch the + existing +<pinchartl> what's your opinion at this point ? [16:13] +<jmondi> I'm a bit more inclined to patch the existing, because at the moment + it seems to me the driver could be implemented without sub-devices, + just with a single video device +<jmondi> also, I saw there is a VEU driver, which seems simple enough to use + as "inspiration" [16:14] +<jmondi> even if it is a mem2mem device +<pinchartl> that sounds good to me +<pinchartl> you need a subdev for the camera sensor +<pinchartl> but you don't need to expose it to userspace [16:15] +<jmondi> yeah, camera sensor apart... +<jmondi> because the CEU has a format conversion unit, that can be modeled as + sub-device visibile to userspace +<pinchartl> the atmel/atmel-isc.c driver seems to be a good example +<jmondi> but I guess it can be left out for now [16:16] +<pinchartl> you don't need to, you can implement format conversion internally +<pinchartl> yes, also +<jmondi> pinchartl: thanks, I would have asked you suggestions on which driver + to look at +<jmondi> and that's all +<jmondi> I would have to clarify if OF support only is enough +<jmondi> because the remote mingor board we should start with, has no OF + support if I'm not wrong, right Magnus? [16:17] +<pinchartl> pxa_camera should also be an option +<jmondi> pinchartl: I gave a look at pxa camera, mostly for OF parsing +<pinchartl> correct, no OF support in Migor [16:18] +<pinchartl> you need to use platform data :-/ +<jmondi> that's bad, it means I have to implement both :/ +<pinchartl> you can start with platform data, and implement OF support later + [16:19] +<jmondi> we should also discuss about hw setup.. but it can be post-poned + after mingor has been made at least booting mainline +<pinchartl> sounds good to me [16:20] +<pinchartl> how about the next two weeks ? do you plan to continue working on + this ? +<jmondi> I'm still intrigued byt the idea of starting with an RZ device from + day 0 +<jmondi> pinchartl: yes, now that my other 2 tasks for IO/core are almost + done, I'll be fully on multimedia +<pinchartl> ok [16:21] +<jmondi> I'll stop here, not to steal the stage to all the others :) +<pinchartl> one more thing, could you please remember to send your status + report by e-mail before the meeting next time ? [16:22] +<dammsan> jmondi: yes there is no OF support for migor +<jmondi> pinchartl: uh, I'll do this right away +<jmondi> sorry about that +<pinchartl> jmondi: no need to for today, I'll include it in the report +<pinchartl> but it helps if I get them in advance +<jmondi> and, pinchartl, I'll ping you a bit more often in next days, hope you + won't mind ;) +<pinchartl> no problem with that :-) [16:23] +<jmondi> (I'll be away from tomorrow to Tues. since we're speaking) +<jmondi> ok, done with me +<pinchartl> next, me +<pinchartl> I've mostly worked on code review and various discussions, + internally and upstream +<pinchartl> as well as additional tasks negotiation [16:24] +<pinchartl> from a code point of view, I've tried to get the VSP rotation and + histogram support merged upstream in v4.12 +<pinchartl> it resulted in yet another fight with Mauro +<pinchartl> up to a point where I can't take his abusive behaviour anymore + [16:25] +<pinchartl> I took a few days to think this over +<pinchartl> among the various options most of them seemed unreasonable to me +<pinchartl> such as challenging him publicly for V4L2 maintainership for + instance +<pinchartl> Hans Verkuil proposed to me to act as an interface between Mauro + and me [16:26] +<pinchartl> to avoid all direct interactions +<pinchartl> I don't really think this would work, but I might give it a try +<pinchartl> in any case, I saw no other option that stepping out from upstream + V4L2 development, at least temporarily +<pinchartl> I will reconsider that decision if the situation changes [16:27] +<pinchartl> (or if I find a better idea) +<pinchartl> in effect, this means I can continue reviewing code and driving + discussions internally +<pinchartl> including architecture discussions +<pinchartl> but I'll remain silent publicly for now +<pinchartl> it also means I will likely need to refrain to author any V4L2 + patch [16:28] +<pinchartl> I still need to discuss this with Hans today, after this meeting +<dammsan> sounds good to me +<pinchartl> for the next two weeks, I plan to work on the multi-camera setup + and try to get it working +<pinchartl> VSP fences support is effectively on hold, I can't work on that + [16:29] +<dammsan> you can also consider putting mauro on fire +<pinchartl> I've considered that, but I don't think it will help +<pinchartl> he will fight back, and it would just create a bit mess, most + likely without any concrete improvement +<dammsan> he looks like he may burn well +<dammsan> probably +<pinchartl> dammsan: let's not resort to personal non-technical attacks + [16:30] +<pinchartl> that's it for me for today +<pinchartl> if any of you wants to discuss this further let's do so after the + status updates [16:31] +<pinchartl> next, dammsan +<neg> quick question, 'reviewing code internally' means no public review of + patches? +<dammsan> no update from my side, currently installing migor in the remote + access rack +<pinchartl> neg: correct. let's discuss the implications after the status + update [16:32] +<pinchartl> dammsan: thank you +<pinchartl> I assume you'll now try to get Migor to boot mainline ? +<dammsan> once it is installed yes [16:33] +<pinchartl> thank you +<dammsan> thanks +<pinchartl> next, Morimoto-san +<morimoto> A) What have I done since last time +<morimoto> continue OF-graph posting. I got response from Rob, but he mentions + small details which is related to ALSA SoC, not to OF-graph. +<morimoto> BSP team reported Sound issue. Almost all bugs are fixed. But some + noise issue was not yet solved. I'm thinking this is related to + board specific clk issue (L/R clock gets interference from Bit + clock) +<morimoto> 8ch camera datasheet export paper work +<morimoto> created periupport script +<morimoto> shared H3/M3 VIN issue to you guys ;P +<morimoto> B) What I plan to do till next time [16:34] +<morimoto> continue OF-graph posting +<morimoto> continue sound noise issue fix +<morimoto> 8ch camera board check by using demo program with BSP team +<morimoto> C) Problems I have currently +<morimoto> OF-graph stalling +<morimoto> --EOT-- +<pinchartl> thank you +<pinchartl> when do you think you will be able to verify the multi-camera + setup with the demo program ? [16:35] +<morimoto> According to BSP team, I and Magnus will check it on this Fri +<dammsan> huh, good to know +<dammsan> =) [16:36] +<pinchartl> :-D +<morimoto> dammsan: this means you need to bring it to Renesas Office on Fri + :P +<pinchartl> I'll wait until this weekend before working on it then +<pinchartl> could you post a status update when you will be done on Friday ? + [16:37] +<morimoto> Of course I will check 2 board which will be ship to Laurent/Niklas + after May +<pinchartl> and Magnus, will you be able to reinstall it in your remote access + setup after your done, to allow me to work on it during the + weekend ? +<morimoto> pinchartl: sure +<pinchartl> thank you [16:39] +<dammsan> pinchartl: not sure about when i will get time to do that +<morimoto> I think all needed 8ch camera datasheet/information exist on Wiki + now. do we still missing something ? +<pinchartl> dammsan: could you at least send me an e-mail when you will be + done ? and also notify me if you get delayed ? +<dammsan> it depends on how long time is needed in the renesas office [16:40] +<pinchartl> morimoto: I still don't know what the small microcontroller inside + the cameras does exactly. do you have any information about that ? + it's connected to the I2C control bus, and controls the sensor + power down signal +<dammsan> once it is working i will reinstall it in the remote access rack + [16:41] +<pinchartl> dammsan: you don't have to work around the clock obviously :-) but + for planning purposes, it would help if you could let me know at + the end of Friday if there will be delays +<morimoto> pinchartl: do you mean U402 ? and I think you are asking it to IMI + guys ? [16:42] +<pinchartl> morimoto: yes, U402. I've asked the IMI person who sent me the + schematics, but haven't received any answer +<dammsan> i highly doubt things will start workin on friday +<morimoto> OK, I will push him +<dammsan> and we have meetings most of the afternoon +<dammsan> so i think you can assume you will not get it this weekend [16:43] +<pinchartl> dammsan: ok. let me know if that changes then +<dammsan> will let you know once it is reinstalled +<dammsan> thanks +<pinchartl> morimoto: I see your e-mail report contains a list of patches. do + I need to include them in the meeting report, or will they be + picked up by your scripts ? [16:44] +<pinchartl> while waiting for that answer [16:45] +<pinchartl> neg: your turn +<neg> a) +<neg> - Fixed up some small CSI-2 stuff, patches pending waiting further +<neg> work before I post them. +<neg> - Had discussions with Laurent, Kieran and Sakari about V4L2 +<neg> extensions needed to support ADV7482. +<neg> - Took a stab at at extending the of graph framework to be able to +<neg> iterate over all DT nodes in a graph connected by endpoints. But +<neg> ceased work after the talk above since the core issue can +<neg> hopefully be solved in a better way and then there would be no +<neg> users of this. [16:46] +<neg> - Tried to help out as much as possible with the 8-channel VIN +<neg> prototype Ulrich and Laurent are working on. +<neg> b) +<neg> - Respin CSI-2 and VIN patches with my new found knowledge of V4L2 +<neg> async framework. +<neg> - Keep supporting 8-channel VIN if needed. +<neg> - Address any review comments on VIN and CSI-2 patches. +<neg> c) +<neg> - No review or other activity on VIN patches, the series [PATCH +<neg> 00/16] rcar-vin: fix issues with format and capturing' IMHO ready +<neg> to be picked up upstream but needs reviews. +<neg> Also Friday 14/4 and Monday 17/4 are holidays in Sweden and I will be + out of town at least on Friday, so my response times are reduced between + those dates. +<pinchartl> thanks for letting us know +<morimoto> pinchartl: I think bugfix patches of D) ? it will be pickuped + automatically by our script. you can drop it. thanks [16:47] +<pinchartl> those two days are public holidays in Finland too +<pinchartl> morimoto: thank you +<pinchartl> regarding the rcar-vin series +<pinchartl> I can review it internally [16:48] +<pinchartl> again, let's discuss that after the status updates +<pinchartl> uli___: your turn +<uli___> so the csi purports to capture frames from the max9286, but it + doesn't really +<uli___> i tried turning off integrity checks, but to no avail +<uli___> i guess the data is not valid; maybe the virtual channel setup is + wrong? [16:49] +<uli___> that's pretty much it. two suggestions for friday: +<uli___> 1. dump the registers of the max92* and ov10635, if it works +<uli___> 2. dump the microcontroller, if you have an isp programmer lying + around +<uli___> it has 8k of rom, and most of it will be ov10635 register settings +<uli___> should be easy to reverse-engineer... [16:50] +<pinchartl> uli___: do you think that U402 is an I2C master ? +<pinchartl> I thought it was a slave +<uli___> the driver code suggests so +<pinchartl> ouch +<uli___> it says that linux doesn't support multi-master busses +<uli___> and that it has to wait for the attiny to finish because of that +<pinchartl> that would require opening the camera, I'm not sure if that's + feasible [16:51] +<uli___> oh, i see... +<pinchartl> but if the microcontroller indeed configures the sensor by itself, + we might have issues, yes +<uli___> well, that's it from me [16:53] +<pinchartl> thank you for the suggestions +<pinchartl> that's it for the status updates +<pinchartl> Topic 2. VIN issues on H3 ES2.0 and M3 ES1x/M3W [16:54] +<pinchartl> Morimoto-san has reported VIN-related issues in the wiki +<pinchartl> + (https://osdr.renesas.com/projects/linux-kernel-development/wiki/R-Car-Gen3#VIN-issue) +<pinchartl> we don't have much information at this point though +<pinchartl> so there isn't much to discuss +<pinchartl> but I have a question [16:55] +<morimoto> Yes. but it is just information, and no W/A at this point. +<pinchartl> morimoto: do those issues impact the multi-camera setup we're + trying to get working ? +<neg> morimoto: W/A == Wanted Action? +<pinchartl> neg: Work Around +<pinchartl> (I assume) +<morimoto> yes Work Around, sorry [16:56] +<neg> thanks :-) +<morimoto> pinchartl: According to BSP team, upstream is supporting 2 Lane ? +<morimoto> 1 lane, and 4 lane have no issue +<morimoto> but 2 lane has issue on M3 +<morimoto> BSP team is using H3 [16:57] +<morimoto> and our remote access is using M3 +<pinchartl> dammsan: would it be possible to switch the remote access setup to + H3 ? +<morimoto> pinchartl: 1 question. are multimedia people tring to 8ch directly + ? [16:58] +<morimoto> I though 1ch camera as fist step [16:59] +<pinchartl> morimoto: no, we're trying to capture from a single camera first +<morimoto> OK +<morimoto> So then it is using 1lane ? maybe M3 +<morimoto> s/mabe M3// +<uli___> 4 lane [17:00] +<dammsan> pinchartl: i can attach the camera board to H3 instead [17:01] +<dammsan> but then our ground might become more stable +<dammsan> i mean more unstable since it is changing +<pinchartl> I think this can wait until Friday +<morimoto> sorry I was wrong. CSI40's 1lane and 2lane are NG. CSI40 4lane is + OK. CSI20 is all OK +<dammsan> after the hardware has been verified in the renesas office i will + use the same one for the remote access +<pinchartl> if you get it to work on H3 on Friday but can't on M3, then we'll + switch to H3 :-) [17:02] +<dammsan> of course if you have any special preference then we will follow + that +<pinchartl> I think we're done with status updates [17:03] +<pinchartl> sorry, with VIN :-) +<pinchartl> Topic 3. OSS Japan trip +<pinchartl> (FYI, my talk at OSS Japan has been approved) [17:04] +<pinchartl> we need to start booking planes and hotels +<pinchartl> morimoto: can we proceed with Renesas' blessing ? +<morimoto> blessing = trip cost ? [17:05] +<morimoto> or meeting ? +<pinchartl> blessing as in getting authorisation to book the trip, and + invoicing it to Jinso [17:06] +<morimoto> Maybe it is OK unless you enjoyed party like Oil tycoon ;P +<pinchartl> damn, my cunning plan has been understood :-) [17:07] +<pinchartl> we'll keep the costs down as usual [17:08] +<pinchartl> no champagne, we'll just drink nihonshu :-) +<pinchartl> jmondi: kbingham: neg: you can proceed booking tickets +<pinchartl> uli___: you could too, but you mentioned you won't be able to + join, right ? +<uli___> no, i won't. sorry. [17:09] +<morimoto> Renesas will pay up to Economy class for flight. Of course you can + upgrade, but it is your cost ;P +<neg> I assume ppl will book the conference hotel even for code camp days? +<dammsan> "up to Economy class" - makes it sound ike there is something + lower? =) [17:10] +<neg> dammsan: United? +<dammsan> haha, if you prefer to be dragged out +<neg> haha :-) +<jmondi> what days we said again? 26th to the 2nd? [17:11] +<pinchartl> jmondi: 29th to 3rd +<pinchartl> (Monday to Saturday) +<pinchartl> I suggest arriving on the 28th at the latest +<pinchartl> (that's what I'll do, in the morning) +<pinchartl> and leaving on the Sunday, or later if you want to take some time + to visit Tokyo [17:12] +<pinchartl> please be careful about the jetlag though +<pinchartl> flights from Europe often land early in the morning +<pinchartl> if you have trouble sleeping in the plane, the next day is very + painful +<pinchartl> you might want to arrive on the 27th to have more time to recover + [17:13] +<jmondi> looking at flights now +<pinchartl> neg: I've booked the conference hotel for the first two days too +<pinchartl> the rate allows changes +<morimoto> And we will have multimedia F2F meeting on 29th 30th ? +<pinchartl> so I might move to a different location after we decide on the + meeting location +<pinchartl> morimoto: correct. we still haven't decided where to host that + [17:14] +<morimoto> OK +<pinchartl> I would appreciate if our valued Japanese and Japanese resident + team members could advise on appropriate meetings locations +<morimoto> OK, I and Magnus will try it. dammsan: please say YES [17:15] +<dammsan> YEESS +<pinchartl> thank you :-) +<morimoto> How many member ? [17:16] +<pinchartl> it should be 4 from Europe [17:17] +<pinchartl> Jacopo, Kieran, Niklas and me +<pinchartl> I assume Magnus and you will join too +<pinchartl> I don't know who else would like to attend from Japan +<pinchartl> we will have a multimedia team meeting, but I also want to use + this opportunity to work on the multi-camera setup with local + access to the hardware [17:18] +<pinchartl> so I'd like part of those two days to be a code camp +<pinchartl> next topic, upstream V4L2 development [17:19] +<neg> If I understnad the mail thread corretly Wolfram won't be there so no IO + meeting to conflict with, but can't see any feedback from Geert. Anyone + know if extra days will be needed for Core meeting? +<pinchartl> neg: I don't know. let's ask geertu [17:20] +<neg> geertu: ^ :-) +<pinchartl> I've already explained the situation briefly.

[16:32] +<pinchartl> yes +<pinchartl> the issue is that +<pinchartl> the VSP driver handles the cache +<pinchartl> and performs a cache cleaning +<pinchartl> while the memory is actually mapped uncached [16:33] +<pinchartl> so it makes sense to set DMA_ATTR_SKIP_CPU because the memory is + always mapped uncached +<dammsan> well, i can somewhat agree to that +<dammsan> but i don't understand why this is needed on Gen3 and not on Gen2 +<pinchartl> this will need to be revisited when we'll implement support for + cached mappings in the DU driver +<pinchartl> on Gen2 the buffers are allocated in the V4L2 framework [16:34] +<dammsan> of course the architecture has changed +<pinchartl> sorry, I'm mixing two thinks +<pinchartl> s/thinks/things/ +<pinchartl> on Gen2 DU doesn't use the VSP +<dammsan> i just want to avoid papering over things +<pinchartl> the VSP driver function where we need to set DMA_ATTR_SKIP_CPU + isn't called at all on Gen2 [16:35] +<dammsan> so this is for the DU? +<pinchartl> yes it's for the DU +<dammsan> ok +<dammsan> and it is not needed with V4L2 VSP +<dammsan> if so i'm ok +<pinchartl> for V4L2 VSP buffers are handled by videobuf2 and we already do + the right thing +<dammsan> gotcha thanks [16:36] +<pinchartl> you're welcome +<pinchartl> cache issues are always complex [16:37] +<pinchartl> * Request API +<pinchartl> for the same reason as explained with fences support, I had to + stop working on this upstream [16:38] +<pinchartl> I thus passed the project to Google +<pinchartl> Alexandre Courbot (ex-NVidia, he now works for Google Japan) has + taken over +<pinchartl> I've had a few meetings with him to discuss the implementation +<morimoto> Wow !

[16:39] +<pinchartl> no I don't +<pinchartl> I had to stop all V4L2 upstream API work [16:40] +<pinchartl> I've explained that before (about a month ago I think, or even a + bit more) +<pinchartl> but clearly not well enough as you're now surprised +<pinchartl> I'm sorry about that +<dammsan> i think i explained this to Morimoto-san before as well [16:41] +<morimoto> OK +<dammsan> but we may have some language barrier +<morimoto> Yes, I think so +<morimoto> I'm sorry too +<pinchartl> it's a very unfortunate situation and I did all I could to avoid + it, but unfortunately all I could wasn't enough +<pinchartl> but I didn't want to give up either, which is why I spent the last + month trying to find a way to short-circuit the V4L2 maintainer + [16:42] +<pinchartl> again, I can't announce anything yet, but I hope to receive a + confirmation by the end of this week that we'll propose a + co-maintainer setup for V4L2 +<pinchartl> I don't expect Mauro to easily accept it though, but we're doing + all we can to propose a gradual and smooth transition to maximize + the chances he will accept [16:43] +<pinchartl> I should be able to tell more next week +<pinchartl> and again, please don't share this outside of the team [16:44] +<pinchartl> * DU / VSP initialize sequence +<pinchartl> on my to-do list for the next two weeks +<pinchartl> I've already started looking into it, it needs a bit more work +<morimoto> pinchartl: can I share this information to BSP team ? +<pinchartl> you can share the problem, and tell them that we're working on + trying to fix it, and that more information is expected by the end + of this week [16:45] +<morimoto> OK, thanks +<pinchartl> but please don't share the fact that we're trying to go for a + co-maintainers setup +<pinchartl> * VIN V4L2_FIELD_SEQ_TB/TB feature [16:46] +<pinchartl> neg: what's your plan ? +<pinchartl> still on your to-do list, based on top of the Gen2 cleanup patches + ?

But on this month, Renesas union's recommend is take a day off :P +10:30 < horms> I like your union +10:30 < dammsan> that makes one of us +10:31 < jmondi> dammsan: yes, I've said "does anyone care" because of the XIP thing +10:32 < geertu> What's missing is a DTS for GR-PEACH, right? +10:32 < jmondi> if we upstream that, without XIP support available, only a very minimal kernel image can be booted... +10:32 < jmondi> geertu: yes, that, and RZ pin controller ;) +10:32 < geertu> Well, it's a first step +10:32 < morimoto> horms: it is "Happy Monday", not "Lucky Monday" :) +10:32 < jmondi> geertu: http://jmondi.org/git/linux/commit/f38567427d2db4a8d14001f8aba860a307b41186 +10:32 < geertu> jmondi: That's true for genmai and RSK, too +10:32 < horms> morimoto: sorry, my bad +10:33 < jmondi> geertu: true indeed +10:34 < geertu> jmondi: Does the GR-PEACH work without the pinctrl driver? +10:34 < jmondi> geertu: I have not tried tbh... +10:35 < jmondi> I don't see why not, if pins are configured properly in u-boot...

That can never work with multi_v7_defconfig +10:43 < jmondi> horms: geertu: I've got some XIP and non-XIP configs for peach I can share +10:43 < horms> geertu: yes, i think the conversation need to happen in the context of XIP +10:43 < geertu> IIRC, Arnd was on the "good" side of the discussion about XIP support +10:45 < horms> I think in Arnds opinion in-tree defconfigs are mainly there for the convenience of him and build bots, and that real users use out-of tree defconfigs. I do not share this opinion. +10:45 < horms> But it does imply that more defconfigs = bad +10:45 < dammsan> Does that mean more boards = bad? =) +10:46 < horms> To me that is a natural extension of the argument, but I'd be surprised if Arnd sees it that way +10:46 < geertu> For XIP and memory-constrained boards, there's no other solution than a separate defconfig +10:46 < dammsan> hehe +10:46 < geertu> or defconfig snippet +10:46 < horms> To be clear, I am not against this. I'm just making recomendations based on my experiences (with Arnd) +10:47 < horms> I think discussing a snippet would be worthwhile +10:49 < geertu> For arm64, no other defconfigs are allowed +10:50 < morimoto> Does previous topic was finished ? if so I have 1 topic +10:50 < horms> see comment above :) +10:50 < geertu> So I think we need an rcar3_defconfig in Simon's repo +10:50 < geertu> In a separate branch (which people can merge), also merged into the devel branch +10:50 < geertu> s/rcar3_defconfig/renesas_defconfig/ +10:51 < horms> we can try that if you think its worthwhile. but i think its unfortunate that upstream policy leads to out-of-tree patches +10:51 < geertu> That's an interesting point of view +10:52 < pinchartl> geertu: merging such branches is always a bit painful +10:52 < pinchartl> for instance when bisecting +10:52 < geertu> True +10:53 < pinchartl> by the way, is there a way to tell git bisect to cherry-pick a set of patches at each bisection point ? +10:53 < geertu> However, when bisecting, you want to keep more or less the config you're bisecting +10:53 < pinchartl> that could be DT patches when bisecting driver changes for instance +10:53 < horms> pinchartl: i usually write a script; it would nice if there was such an option +10:54 < geertu> git bisect run? +10:54 < geertu> I usualy stash the local changes I need, and stash apply them after each step +10:54 < geertu> sometimes there are conflicts +10:55 < pinchartl> I guess the run script could spawn a console, yes +10:55 < horms> anyway, these kind of problems are some of the reasons i object to out of tree code +10:55 < pinchartl> s/console/shell/ +10:55 < horms> but I also agree it should be managable for a defconfig +10:56 < pinchartl> I believe there's value in keeping a defconfig (or a set of defconfigs) *somewhere* +10:56 < horms> that i can agree with +10:56 < pinchartl> I've stopped counting the number of times Jinso reported failure to test deliverables due to their kernel config being bad +10:56 < horms> and i am not objecting to storing them in my tree if there is a value to doing so +10:56 < geertu> Well, bisecting an issue is sometimes similar to out-of-tree patches, as the bug may only show up when merging the driver and DT branches +10:57 < geertu> As defconfigs evolve over time, storing them in a VCS is the most sensible thing to do +10:57 < horms> i'm more objecting to upstream belligerence +10:57 < pinchartl> geertu: would it make sense to store the defconfigs in a repository to which we all have commit rights ? +10:58 < geertu> pinchartl: Really? +10:58 < pinchartl> just asking ;-) +10:58 < geertu> Should renesas-drivers pull requests include defconfig updates, too? +10:59 < pinchartl> you'll have fun with the conflicts :-) +10:59 < geertu> Exactly +11:00 < geertu> Maintaining defconfigs that are to be updated regularly is a real task +11:01 < geertu> Perhaps we should continue offline (on periperi-ml), as this affects I/O and MM, too? And Morimoto-san has another small topic to discuss +11:01 < pinchartl> sure +11:02 < morimoto> geertu: can I start my topic ? +11:03 < wsa_> i have a small question, too. +11:03 < wsa_> (after morimoto-san) +11:04 < geertu> morimoto: sure, please go ahead +11:04 < morimoto> Thanks +11:04 < morimoto> it is about Salvator-XS board shipping. +11:04 < morimoto> I will ship XS board to Geert/Marek/Laurent/Niklas as 1st shipping, other guys will receive it as 2nd shipping. +11:04 < morimoto> I can ship it this week in best case. +11:04 < morimoto> pinchartl: I think I need to keep it until 6/M for you ? Because you stay in Japan until 17th ? I can bring it meeting room if you want. +11:04 < morimoto> marex-cloud: neg: you will come to Japan, but I will ship it to OpensourceAB, So I can ship it soon ? +11:04 < morimoto> dammsan: I think OpensourceAB can keep it until after OSS Japan ? +11:04 < morimoto> geertu: you will not come to Japan, so you can receive it without receive trouble? +11:05 < geertu> morimoto: yes I can. Thanks! +11:05 < dammsan> morimoto: correct +11:05 < morimoto> geertu: dammsan: OK, thanks. and pinchartl ? +11:06 < morimoto> marex-cloud: neg: please discuss how to receive it with dammsan +11:06 < neg> morimoto: will do thanks +11:08 < pinchartl> morimoto: please. if you ship it now it will arrive when I'm away, and that will be difficult to handle +11:08 < morimoto> pinchartl: OK. will ship it around 6/ +11:08 < morimoto> +11:08 < morimoto> 6/M +11:08 < pinchartl> you could ship it on the 13th or 14th, then it should arrive when I'll be back +11:09 < morimoto> OK. geertu: thats it from me. thanks +11:10 < geertu> Thank you, Morimoto-san +11:10 < geertu> wsa_: You have a question? +11:11 < wsa_> yup, about a possible renesas-cpg-mssr and i2c-sh_mobile dependency? +11:11 < wsa_> bsp has a commit saying: +11:11 < wsa_> Since renesas-cpg-mssr clk driver has changed its initial function to subsys_initcall, so change the initial function of this module to lower level. +11:11 < wsa_> I may be totally missing something, but I don't see the connection +11:12 < wsa_> and I don't want i2c drivers to be subsys_initcall unless it is utterly necessary +11:15 < wsa_> any idea? +11:16 < wsa_> If it needs digging, we can do that by mail; but I thought it might be obvious for you guys :) +11:17 < shimoda> wsa_: i think we should ask bsp team about this patch "i2c: sh_mobile: Change driver init level(Dien Pham) " +11:17 < wsa_> yes, we can do that as well +11:17 < geertu> They want to avoid probe deferral, which would put it at the end of the list again +11:18 < wsa_> but then maybe, I should collect all the questions I have :) +11:18 < shimoda> I guess this patch is related to power management because Dien-san is a member of power management team. anyway I will ask bsp team later +11:18 < geertu> While they want the i2c bus serving the PMIC initialized early +11:18 < shimoda> ask both bsp team and power management team +11:19 < wsa_> i see +11:19 < wsa_> so this saves a cycle of deferred probing +11:20 < wsa_> and the patch description is a little misleading +11:21 < wsa_> ok, thanks! +11:21 < wsa_> jmondi: do you have a minute after the meeting? +11:21 < jmondi> wsa_: yup +11:22 < geertu> wsa_: I find this patch description less misleading than some others ;-) +11:22 < wsa_> true, "a little" meant to express that :) +11:24 < shimoda> wsa_: geertu: if the description is correct, this patch is reasonable? +11:24 < shimoda> I mean, the patch should revise the description +11:24 < shimoda> and after revised it, should the patch go to upstream? +11:25 < wsa_> I wouldn't like to upstream it if it is not really needed to get the machine alive +11:25 < geertu> A good patch description talks about current state, wy that's a problem, and how to fix it. +11:25 < geertu> wsa_: Note that it's already subsys_initcall() in upstream +11:25 < geertu> subsys_initcall_sync() is _later_ +11:26 < wsa_> It is more a hackish workaround about missing device dependencies +11:26 < wsa_> I see! +11:26 < shimoda> thanks, so I should ask bsp team why they don't want to deffer the driver +11:26 < wsa_> shimoda: wait, geertu has a point there +11:27 < wsa_> but it is still trying to describe a dependency via init levels :/ +11:27 < wsa_> I'll have a closer look +11:28 < geertu> shimoda: If the driver is deferred, it's moved to the end of the list, hence retried after all other drivers have been initialized +11:28 < geertu> Probing really should start taking into account phandles +11:29 < geertu> But that would break circular dependencies... +11:29 < geertu> (doh, not as in "break the circle", but as in "break operation if there are circles" +11:29 < geertu> ) +11:31 < wsa_> It is a tough problem, but it needs to be tackled properly somewhen +11:31 < wsa_> As a maintainer, I am very conservative when people try work around this via init levels +11:32 < wsa_> As I said, only if it is utterly needed +11:32 < wsa_> Sadly, there is already cruft in my subsystem, and it causes hazzles once in a while +11:32 < wsa_> one platform needs it like this the other like that +11:32 < wsa_> but i'll check this patch again +11:34 < shimoda> wsa_: ok, so i'm waiting for wolfram-san. no ask some teams. is it ok? +11:34 < wsa_> yes +11:35 < shimoda> wsa_: i got it +11:35 < wsa_> thank you shimoda-san +11:35 < shimoda> wsa_: you're welcome :) +11:37 < geertu> Anything else to discuss? +11:37 < geertu> Else we can finish +11:38 * Marex is back from outside +11:39 < Marex> dammsan: will handle the email from you tomorrow-ish , OK ? +11:42 < Marex> morimoto: jupp, I'll come to Japan (looking forward to it!!), will discuss with dammsan +11:42 < Marex> morimoto: I'll be back on June 15th (doing a trip of Hokkaido this time), so there's no need to hurry +11:43 < morimoto> Marex: OK, but XS shipping for Marex/neg will be happen in the same time +11:44 < Marex> morimoto: got it :) +11:44 < morimoto> Because it goes to OpensourceAB first +11:44 < morimoto> And OpensourceAB will forward it to you guys +11:44 < morimoto> OpensourceAB can keep it for you. +11:44 < morimoto> You can talk it to dammsan in Japan +11:45 < Marex> morimoto: jupp :) +11:45 < Marex> morimoto: pardon my ignorance, XS is r8a7795 or 7796 ?

The GPU driver will need to switch to explicit fences + too. +<pinchartl> - Cache (DMA ATTR SKIP CPU) performance issue with VSP2 +<pinchartl> Fixed in "[PATCH v2 0/5] R-Car DU: Fix IOMMU operation when + connected to VSP". +<pinchartl> - Handled administrative tasks (additional tasks negotiation, + Tokyo meeting preparation) [16:35] +<pinchartl> - Started looking into H3 ES2.0 display support +<pinchartl> for the next two weeks [16:36] +<pinchartl> - H3 ES2.0 DU support +<pinchartl> - OSS Japan and multimedia meeting +<pinchartl> - Vacation in Japan (from June the 4th to June the 17th) +<pinchartl> ah, I forgot to mention, I've also managed to get my Salvator-X + booting in my board farm, with power controlled through a + beaglebone black and a custom PCB to drive the external power + signal [16:37] +<dammsan> good!! +<pinchartl> now I need to setup remote access to the management machine +<pinchartl> (which at the moment is unfortunately a power-consuming PC, but I + hope to change that at some point) [16:38] +<pinchartl> that's it for me +<pinchartl> dammsan: anything to report ? +<pinchartl> seems we've lost Magnus again [16:40] +<dammsan> not much except that i intend to review your IPMMU DU/VSP/FCP series +<pinchartl> ok +<dammsan> also +<kbingham> I'll ping Mauro to get an ack on those +<dammsan> i would like to know which boards i should bring to the meeting + space +<pinchartl> kbingham: you can ping him on IRC. tell him you're leaving for + Japan tomorrow and that you'd like to know whether he's OK before + that [16:41] +<pinchartl> dammsan: that will be part of the third topic :-) +<dammsan> excellent!! +<pinchartl> Topic 2. Additional tasks for the second batch of Q2 +<kbingham> pinchartl: Yes, the on IRC bit was the part I meant - the Japan + trip is a good idea for a push :) +<pinchartl> has everybody received their SoW for Q2/2 ?

I'm not sure it is OK or not +10:17 < geertu> You mean sh-sci calls dmaengine_pause(), while rcar-dmac doesn't implement it? +10:17 < shimoda> sh-sci driver calls dmaengine_pause() but rcar-dmac doesn't have .device_pause() for now +10:18 < shimoda> geertu: yes +10:18 < shimoda> for now, i don't encounter any problem, but this implementation is storange to me +10:18 < shimoda> s/storange/strange/ +10:19 < shimoda> since we don't have any issue, we can use them as-is though :) +10:20 < geertu> The sh-sci driver has a workaround for the absence of .pause(), cfr. the commit that introduced the call (e7327c09def48ccfd204025726f11b57a19a9c24) +10:21 < geertu> But I agree the DMA implementation of sh-sci is far from perfect +10:22 < geertu> So Magnus suggested to make a test case if .device_pause() is really needed or not? +10:22 < shimoda> geertu: yes +10:24 < geertu> Due to the workaround, I think it's not needed now. +10:26 < geertu> IIRC, dmaengine_pause() can be called in interrupt context, while dmaengine_terminate_all() cannot (but it's possible we still violate that) +10:26 < shimoda> geertu: "it's" means .device_pause? +10:26 < geertu> In the mean time, dmaengine_terminate_all() has been deprecated, in gavor of dmaengine_terminate_sync() or dmaengine_terminate_async() +10:27 < geertu> Yes, I meant .device_pause() is not needed due to the workaround +10:27 < geertu> s/gavor/favor/ +10:27 < shimoda> oh, i don't know dmaengine_terminate_all has been deprecated +10:28 < geertu> dmaengine_terminate_async() can be called from interrupt-context, dmaengine_terminate_sync() cannot +10:28 < shimoda> i see +10:28 < geertu> Perhaps Niklas has a better understanding of the modern DMA API?

+10:16 < geertu> Good question! +10:16 < geertu> dammsan: It's not listed in my SoW ;-) +10:17 < geertu> But as it's part of basic infrastructure, it fits better in core than in any of the other groups +10:18 < geertu> Regarding B, that means we'll have to update U-Boot regularly, as we keep on adding more device support to the DTS? +10:18 < marex-cloud> that's a good question +10:19 < marex-cloud> usually you don't want to update your bootloader in a delivered product +10:19 < marex-cloud> on a devkit, that might be easier +10:19 < geertu> I guess if you TFTP a specific DTB, it will take precedence? +10:19 < marex-cloud> then again, while you're adding more devices to Linux, U-Boot will only support a subset of them (we don't need ie. any of the multimedia stuff in U-Boot, maybe video out, but that's about it) +10:20 < marex-cloud> geertu: for now, I'd like to keep bundling the DT with U-Boot just like we do on other boards +10:20 < geertu> Or is the DTB stored in a separate partition on FLASH, so it cane be updated easily? +10:20 < marex-cloud> geertu: we can unbundle that later, once things are a bit more fleshed out +10:20 < marex-cloud> geertu: also, we'd probably need to patch BL2/BL3 to load two files, U-Boot and DT +10:21 < pinchartl> marex-cloud: what "other boards" ?

+10:22 < pinchartl> I'm fine if U-Boot needs some DT that I don't need to update more often than updating the boot loader itself +10:22 < marex-cloud> pinchartl: eh ? how would that break it ? +10:23 < marex-cloud> pinchartl: OK +10:23 < pinchartl> but I want to be able to load kernel + DT over TFTP and boot them regardless of what DT is bundled with U-Boot +10:23 < marex-cloud> pinchartl: ah, that's fine then +10:23 < marex-cloud> pinchartl: you can use separate DTs for both (although it would be preferred if you didnt :) ) +10:24 < pinchartl> in particular, if U-Boot patches the DT (to set the DRAM size for instance), it has to patch the DT I load over TFTP +10:24 < marex-cloud> pinchartl: U-Boot does patch the DT passed to the kernel with RAM size and ethernet MAC +10:24 < marex-cloud> geertu: well, if that's the case already, we could use that to supply DT to U-Boot +10:25 < pinchartl> marex-cloud: if you want to use the same DT for U-Boot and Linux, then add TFTP support to BL3 :-) +10:25 < marex-cloud> geertu: but I'd rather like to start slow, get the DT support in at all first and then move on to fiddling with BL +10:26 < marex-cloud> geertu: I think these are two tasks which depend on one another, but getting the DT support into U-Boot with bundled DT is much easier then complicating it with passing DT from BL +10:27 < marex-cloud> pinchartl: just use U-Boot as your TFTP client ... +10:27 < geertu> marex-cloud: OK, bundling a (minimal) DT is fine. +10:28 < marex-cloud> geertu: I'd like to bundle the same DT as we use in linux, not a minimal one ... +10:29 < marex-cloud> geertu: the less we diverge with the DT, the better +10:29 < geertu> marex-cloud: OK, but we're still developing "the one in Linux" +10:29 < marex-cloud> geertu: you can sync the one in U-Boot with the one in Linux, that's OK +10:30 < marex-cloud> geertu: until Linux pulls out the DTs from it's codebase, we don't have much other options anyway ... +10:31 < geertu> OK +10:31 < geertu> Thank you, Marek! +10:31 < geertu> Next is Simon +10:33 < horms> Todo Update +10:33 < horms> NULL +10:33 < horms> A) What have I done since last time +10:33 < horms> B) What I plan to do till next time +10:33 < horms> No Core task at this time +10:33 < horms> C) Problems I have currently +10:33 < horms> D) Posted/Accepted bugfix patch +10:33 < horms> None +10:33 < horms> -- end -- +10:33 < geertu> Thank you, Simon! +10:33 < geertu> Next is Laurent +10:34 < pinchartl> nothing on my side +10:34 < pinchartl> as usual :-) +10:34 < geertu> Thank you, Laurent! +10:34 < geertu> Next is Jacopo +10:35 < jmondi> yep +10:35 < jmondi> A) RZ pinctrl: sent v6 off-line to collect feedback on how to handle pinmux flags inside the driver +10:36 < jmondi> A) pinconf generic: sent patch to add output-enable, on which the RZ pinctrl depends on +10:36 < jmondi> B) Keep working on this (mostly background due to high latencies in receiving feedbacks from gpio people) +10:36 < jmondi> C) Null +10:36 < jmondi> --eot-- +10:37 < geertu> Thank you, Jacopo! +10:38 < geertu> Topic 2. Core additional tasks +10:39 < geertu> Is anyone interested in doing a core additional task in Q3 (targets middle of August and middle of September)? +10:39 < geertu> Topics to consider: +10:40 < geertu> - Taking over R-Car Gen3 CPUFreq support +10:40 < geertu> - Salvator-XS board support +10:40 < geertu> - R-Car D3 and Draak board support +10:40 < geertu> - DMA (as usual ;-) +10:40 < geertu> - As v4.14 will be the next LTS, I think it would be good to tackle the +10:40 < geertu> missing DT description tasks by then. +10:40 < geertu> Whether these are done in the context of base or additional contracts is +10:40 < geertu> TBD. +10:40 < geertu> - H3 ES2.0 PFC tasks +10:40 < geertu> - Emergency shutdown +10:40 < geertu> - Detection = I/O +10:40 < geertu> - Handling = core +10:41 < horms> What is involved in the first two? +10:41 < neg> As previusly indicated I'm interested in Emergency shutdown :-) +10:42 < geertu> horms: Khiem posted a first version last year. It received some review comments, but they were never adressed. +10:43 < geertu> IIRC, the framework itself has seen some changes too, so the patches need to be updated. +10:43 < horms> Ok, I'd be happy to look at that loose end. +10:43 < geertu> The task is +10:43 < geertu> CPUFreq,v4.13,public,khiem,R-Car Gen3 CPUFreq support +10:43 < geertu> There's a related task +10:43 < geertu> DevFreq,?,noplan,?,GPU needs DevFreq, as DVFS is shared between CPU and GPU +10:44 < geertu> but that's more complicated, as we don't support the GPU in upstream +10:45 < geertu> so it may be more appropriate to consider the latter as a separate task +10:45 < jmondi> geertu: pinchartl: I only have 1 additional task for Q3 and I'm not sure where it will be allocated, but generally speaking I would be interested in looking in cpufreq.. Maybe I can help Simon on this in Q4? +10:46 < geertu> jmondi: It's a bit too early for Q4. And we'll have to see how it goes first. +10:46 < geertu> For D3/Draak one important question is: when will hardware be available? +10:46 < pinchartl> jmondi: if you have time for multimedia in Q3, I'd like you to continue the work on the max9286 and rdacm20 drivers +10:47 < jmondi> pinchartl: that will be most of my base time, on top of which there will be an additional task tbd +10:47 < dammsan> geertu: i think remote access for D3 may be possible for first batch +10:47 < shimoda> geertu: i will get D3 boards in early July. but i doubt it though... :) +10:48 < geertu> dammsan: Good to hear that! +10:48 < dammsan> shimoda: any other boards available? =) +10:48 < geertu> Japanese "I doubt it" == "No way!"? ;-) +10:48 < dammsan> "Maybe" == "No way" +10:48 < dammsan> =) +10:48 < shimoda> anyway I negotiate someone we must need a board at least :) +10:48 < marex-cloud> geertu: since when do japanese speak english ? :) +10:49 < shimoda> dammsan: :) +10:49 < geertu> Do other D3 boards exist? +10:50 < dammsan> Not sure +10:50 < shimoda> I don't know +10:50 < horms> I think there is a schrodinger board +10:50 < dammsan> shimoda: how about other SoC? =) +10:51 < shimoda> but, i heard some option boards exist for D3 +10:51 < pinchartl> dammsan: speaking of boards, is there a plan to send H3ULCBs to team members ? +10:51 < geertu> shimoda: The MCU-board for CN50? +10:52 < shimoda> dammsan: about V3M board, i'm asking board team when we can buy it +10:52 * marex-cloud would be interested in M3ULCB , since they're not in stock anywhere :-/ +10:52 < dammsan> pinchartl: i think ULCBs should be purchased from within EU +10:52 < marex-cloud> also, what about the RPC driver ? Can we do something about that ? +10:52 < shimoda> geertu: sorry i don't know the detail +10:52 < dammsan> however it might be wise to wait with H3 to get ES2+ +10:53 < pinchartl> dammsan: that's fine with me +10:53 < marex-cloud> dammsan: I tried, they're not in stock, more available in ~1 month ; digikey cannot ship them from US due to restrictions +10:53 < dammsan> shipito.com =) +10:54 < pinchartl> dammsan: have you used that to work around export restrictions ? +10:54 < dammsan> (they can fill in the customs declaration for you if you pay them) +10:54 < dammsan> i use them to get stuff from the US to JP all the time +10:54 < marex-cloud> dammsan: ooooooh :-) +10:55 < marex-cloud> dammsan: thanks +10:55 < pinchartl> https://www.shipito.com/en/help/faq#restricted +10:55 < dammsan> but i fill in my papers by myself +10:57 < marex-cloud> or maybe it's worth waiting for the ULCB to become available in EU again ? +10:57 < dammsan> no stress from my side +10:59 * marex-cloud really wants to test U-Boot on it :-) +10:59 < marex-cloud> dammsan: any opinion on the RPC driver ? +11:00 < pinchartl> (unrelated question as everybody seems idle: should I add comments such as "Under development" to the periupport file, or should I just leave the non-upported commits untouched ?) +11:01 < horms> <2c>seems useful to me </2c> +11:01 < pinchartl> horms: thanks +11:01 < dammsan> marex-cloud: sorry no time to look into things yet +11:02 < marex-cloud> dammsan: no stress :-) +11:05 < pinchartl> horms: another related question, are commit IDs in your arm64-dt-for-v4.13 branch stable ? can I use them in periupport, or will the commits be cherry-picked/rewritten when going upstream ? +11:06 < horms> simple answer: yes +11:06 < pinchartl> horms: thanks +11:06 < pinchartl> (unless something bad happens I assume, but that's ok) +11:06 < geertu> horms: Unless Olof is in a bad mood ;-) +11:06 < horms> That branch has been merged into ARM-SoC and is closed +11:06 < horms> Olof was a bit grumpy but pulled them anyway +11:07 < horms> However, before things are pulled they may change +11:07 < pinchartl> horms: how so ? +11:08 < horms> well for one things I make errors and fix things +11:08 < horms> for another people ask me to drop patches +11:08 < horms> and lastly the ARM-SoC maintainers ask for changes from time to time +11:09 < geertu> Anyone else interested in doing a core additional task? +11:09 < geertu> Well, you can still email me after the meeting. +11:09 < marex-cloud> geertu: what's missing on the XS ? +11:09 < pinchartl> horms: of course. fair enough. I was mostly interested in knowing whether the process involves modifying commits as part of the normal workflow +11:09 < geertu> Salvator-XS,?,plan,marek,VersaClock 5P49V6901A clock generator driver +11:10 < horms> pinchartl: no, its just for exceptions +11:10 < geertu> marex-cloud: I assume you're already looking into that? +11:10 < dammsan> geertu: at some point i would like to tackle the "multiple-devices" per pin issue we have with DT and PFC +11:10 < geertu> Plus Salvator-XS has H3 ES2.0, which has very limited PFC support for now. +11:11 < marex-cloud> geertu: patches are available, I sent them to dammsan to get an OK from him to submit to linux-clk ; will CC renesas-soc once cleared +11:11 < geertu> But lots of pins/functions/groups can be mined from the BSP. They just need review/testing. +11:11 < marex-cloud> geertu: speaking of that, dammsan , do I need to ask for clearance to submit patches from you always or shall I just submit ? +11:11 < marex-cloud> dammsan: which way do you prefer to handle this ? +11:12 < dammsan> good question +11:12 < dammsan> i think stuff ordered directly from my is good to handle the existing way +11:12 < marex-cloud> dammsan: if I ask for clearance every time, you have more control, but it introduces delays +11:12 < dammsan> however for your base task time there is no need to check with me +11:12 < geertu> Should all patches follow the reverse money path? ;-) +11:13 < dammsan> so if you have a strict contract then talk to me +11:13 < dammsan> otherwise ignore me +11:13 < dammsan> makes sense? +11:13 < dammsan> i expect everyone to coordinate with the group leaders anyway +11:14 < pinchartl> dammsan: just curious, is there any reason to hold off by default on posting patches ? +11:14 < dammsan> not really +11:14 < geertu> Most H3 ES2.0 PFC work needed is small things, not worth a full additional task. So I'd recommend just doing it when scratching an itch... +11:15 < dammsan> geertu: i noticed that ULCB has a SCIF1 as secondary debug port +11:15 < geertu> dammsan: What's the "multiple-devices" per pin issue again? +11:15 < dammsan> (that may not be populated on the board) +11:15 < geertu> dammsan: Salvator-X has, too? +11:16 < marex-cloud> dammsan: I don't quite get it, so I might just ask for your clearance until I see the pattern +11:16 < dammsan> on those two pins for RX and TX we can chose between SCIF and HSCIF +11:16 < dammsan> marex-cloud: thats fine +11:16 < dammsan> geertu: so the hardware allows us to select either SCIF or HSCIF +11:17 < dammsan> but can we do that with current DT? +11:17 < marex-cloud> dammsan: thank you +11:17 < dammsan> (without setting sofware policy) +11:17 < dammsan> that's what i mean by "multiple devices" per pin +11:18 < dammsan> i want to describe the hardware in DT =) +11:19 < geertu> dammsan: DT overlay? (modulo aliases, for which I have a hackish patch) +11:19 * pinchartl will have to leave soon +11:20 < pinchartl> I'd like to briefly discuss meeting schedules if that's fine +11:20 < marex-cloud> dammsan: is that what ie. IMX does now ? Each peripheral has a list of per-pin settings instead of what we have on RCar3 PFC ? +11:20 < pinchartl> dammsan: you expressed the desire to group multiple meetings in the same day +11:20 < dammsan> yes +11:20 < pinchartl> for this week it's too late, I'll send the invitation for the multimedia meeting for tomorrow +11:20 < dammsan> i would prefer that if possible +11:20 < dammsan> sure +11:20 < pinchartl> but for the next one, how would you like to handle this ? +11:20 < dammsan> not sure what other people think +11:21 < dammsan> i like to group together meetings and paperwork into a single day if possible +11:21 < geertu> You want to have Core, I/O, and MultiMedia meetings on the same day? +11:21 < dammsan> not sure what is the best way to deal with things +11:21 < geertu> Or on the same day of week? And switch to tri-weekly? +11:22 < dammsan> i just know that several meetings per week starting in the afternoon kind of kills the evening schedule pretty good +11:23 < geertu> With all meetings on a single day, it may be difficult to meet timezone constraints. +11:23 < dammsan> yeah there is that for sure +11:23 < pinchartl> we shouldn't start earlier than 8:00 British time +11:23 < dammsan> i would like to know if the other japanese guys have some opinion about schedule +11:24 < pinchartl> that's 16:00 Japanese time +11:24 < pinchartl> if we have three one-hour meetings, that's up to 19:00 in Japan +11:24 < pinchartl> 08:00-11:00 in the UK +11:24 < pinchartl> 09:00-12:00 in central Europe +11:24 < pinchartl> and 10:00-13:00 in Finland +11:25 < geertu> In Summer +11:25 < pinchartl> yes +11:25 < pinchartl> we'd have to strictly cap every meeting to one hour though +11:25 < dammsan> for me, i'd rather spend one day and continue after EU lunch time instead of two days +11:25 < pinchartl> which should be enough for status reporting +11:26 < pinchartl> but might be short if we need to start discussing issues +11:26 < pinchartl> or maybe 3x 1.5h meetings then ? +11:26 < neg> Maybe status reporting can be moved to email, as done for the IO group and only talk about points of interesst during the meeting? +11:26 < dammsan> with 2 group meetings on tue + wed and two days in the renesas office that kind of kills 4 nights without any chance for code output +11:27 < dammsan> if we could do it before EU lunch time then that would be very nice IMO +11:27 < pinchartl> neg: we already do status reporting through e-mail. I think it's useful to copy&paste it here, as it gives me (and others) a chance to ask questions +11:29 < neg> pinchartl: There is no call for A/B/C updates for the Core meeting by mail, but I agree that pasting it here is usefull +11:29 < dammsan> alternatively do brief 30 minutes per group before lunch, and schedule afternoon on-demand +11:29 < dammsan> but do that on a single day for all groups +11:30 < dammsan> perhaps that would make the situation worse for you guys +11:30 < pinchartl> I don't mind personally +11:30 < pinchartl> it would be nice if the meetings didn't overlap lunch time though +11:31 < dammsan> it is good with dinner break at this side of the world too +11:31 * marex-cloud doesn't mind either way +11:32 < dammsan> how about restricting to only A/B/C before lunch EU time +11:32 < dammsan> and propose afternoon topics on the fly +11:32 < dammsan> then have a lunch/dinner break +11:32 < dammsan> and get back to it +11:32 < jmondi> it's fine for me as well, but generally speaking, 1 day of just meetings it's really bad :) +11:33 < jmondi> but I understand the timezone thing... +11:33 < dammsan> yeah coming home at 21:00+ several days in a row with no code output kind of sucks +11:33 < pinchartl> another idea +11:33 < pinchartl> if it's just A/B/C in the morning +11:33 < pinchartl> and if we have the three groups on the same morning +11:33 < pinchartl> do we need to split the meeting between groups ? +11:34 < pinchartl> we could have a combined A/B/C +11:34 < dammsan> sounds good to me +11:34 < neg> I like that idea as well +11:34 < pinchartl> but then who will be responsible for writing reports ? :-) +11:35 < pinchartl> we could take turns I suppose +11:35 < dammsan> perhaps the group leaders need to bid on each patch =) +11:35 < pinchartl> I have to go now I'm afraid +11:36 < pinchartl> I'll let you continue the discussion and read the result after lunch +11:36 < dammsan> sure +11:36 < dammsan> bon apetit +11:36 < dammsan> ! +11:36 < pinchartl> (oh, and schedule-wise, Tuesday is probably the worst day for me, as that's the day of my weekly Linux developers lunch in Helsinki) +11:36 < dammsan> geertu: what is your opinion about meeting schedule? +11:37 < geertu> dammsan: We could move the A/B/C to email, and use the meeting for questions/discussions +11:37 < pinchartl> dammsan: if you're still at the office, could you check with Morimoto-san about the Salvator-XS shipping issues ? in particular I'd like to know whether a permanent import is fine, as explained in my last e-mail +11:38 < geertu> That frees up some time +11:38 < pinchartl> geertu: I'd still like to copy&paste the status report here, as it often leads to questions (at least for me) +11:38 < dammsan> pinchartl: i'm not in the renesas office. i will setup a H3 ES2 board for your remote access +11:38 < pinchartl> copy & paste shouldn't be long +11:38 < pinchartl> dammsan: thank you +11:38 < pinchartl> now I really have to go +11:38 * pinchartl is gone +11:39 < dammsan> geertu: that sounds good to me +11:39 < geertu> I'd prefer not to split the meeting in before/after lunch/dinner +11:39 < dammsan> same here ideally +11:39 < geertu> Just have 1 hour for each group? And each group leader is responsible for the report for his group, as is currently done +11:40 < dammsan> that seems pretty straightforward and good to me +11:40 < geertu> Round-robin reporting of a huge 3 hour meeting with topics you may not be interested in is a killer +11:40 < dammsan> yeah for sure +11:40 < dammsan> just want to avoid having that multiple days in a row =) +11:41 < geertu> So it's all about making effective use of the limited time (1 hour/topic) +11:41 < dammsan> i agree +11:41 < geertu> s@topic@group@ +11:41 < dammsan> geertu: can we improve how we handle SCIF/HSCIF in DT somehow? +11:42 < geertu> Or do we need a different split in 4 submeetings: Core. I/O, MultiMedia, Common? +11:43 < dammsan> as long as they are on the same day i'm happy =) +11:43 < geertu> I/O is usually a short meeting +11:43 < geertu> MM is usually long? +11:43 < dammsan> similar to core i think +11:43 < geertu> dammsan: pinctrl-0 and pinctrl-1, cfr. SDHI? +11:43 < neg> yes I think MM tends to be a bit longer then Core +11:45 < jmondi> a bit longer, yes +11:45 < dammsan> geertu: that's for two states within same device, no? +11:46 < geertu> dammsan: I know. As SCIF and HSCIF are handled by the same driver, we could hack in something? +11:46 < dammsan> hacking is possible for sure +11:47 < dammsan> maybe this is similar to the I2C master switch topic +11:47 < marex-cloud> dammsan: do you need to switch between those two at runtime ? +11:47 < geertu> In some sense all pinctrl is "software policy" +11:47 < geertu> have you looked at Pantelis' connector work? +11:48 < dammsan> i saw a talk from him +11:48 < marex-cloud> geertu: did that make it to mainline ? :) +11:48 < geertu> I think it would allow to describe a serial port the way we wwant +11:48 < dammsan> marex-cloud: i want to separate hardware description and software policy +11:48 < geertu> marex-cloud: No, just like DT overlays +11:49 < dammsan> if we can use both SCIF and HSCIF on pins then our DT should represent that somehow +11:49 < marex-cloud> geertu: DTOs are in mainline, I think the missing part is the configfs interface for loading them +11:49 < geertu> For the hungry people: shall we conclude the Core meeting itself?

(Toshiba and Matsushita even aren't) +11:17 < wsa_> Gen2 had SDHI for SD and MMCIF for MMC (simply spoken) +11:17 < marex-cloud> http://git.denx.de/?p=u-boot.git;a=blob;f=drivers/mmc/uniphier-sd.c;h=3c462bd5835e9e4efae745791fdaaff80a4c2af5;hb=HEAD +11:17 < marex-cloud> here is a better register description ^ +11:17 < wsa_> Gen3 has only SDHI which gained MMC support +11:18 < geertu> Isn't this I/O? :-) (oh, U-Boot is core) +11:18 < kbingham> marex-cloud: geertu: If C) is causing problems I can see if I can help somewhere yes. Can someone send me a patch reference / ML links please ? +11:19 < marex-cloud> kbingham: https://patchwork.kernel.org/patch/9707899/ +11:19 < marex-cloud> wsa_: I only have Gen3 , so I'm talking about SDHI +11:20 < jmondi> I need to be away for ~15 mins... If IO report starts and I'm named, I may reply a bit late (No IO updates btw).. sorry about this +11:20 < marex-cloud> wsa_: which looks like the same block that's in Uniphier ... see above +11:20 < geertu> Let's continue with core... +11:20 < geertu> Thank Marek! +11:20 < geertu> Next is Magnus +11:20 < marex-cloud> geertu: so uh, I'd like to know which block it is ^_^' +11:20 < marex-cloud> we can do that later +11:21 < dammsan> [1;5Dno special update from me thanks +11:22 < geertu> Thank you, Magnus! +11:22 < geertu> Next is Ulrich +11:22 < uli___> nothing to report here +11:22 < dammsan> regarding SDHI, search for mn5774 for perhaps related panasonic IP +11:22 < marex-cloud> [11:22:28] <Masahiro Yamada> I asked some hardware engineers. Looks like Panasonic/Matsushita IP. +11:22 < geertu> Thank you, Uli! +11:22 < marex-cloud> dammsan: thank you +11:23 < geertu> So far for status reporting from the regular core members. +11:23 < marex-cloud> dammsan: might be worth adding that piece of trivia to the driver / DT +11:23 < geertu> Anything core-related from Wolfram or Kieran? +11:24 < wsa_> nope +11:24 < kbingham> geertu: I've ordered a new BusBlaster +11:24 < kbingham> I can't get my existing one working with OpenOCD (its an IMG varient ... ugh ) +11:24 < wsa_> marex-cloud: the register description in the link above is definately SDHI +11:24 < geertu> v4? +11:25 < kbingham> geertu: Actually I've ordered the v3 ... for better compatibility - With a desire that I should hope to see how to get JTAG connected at somepoint using OpenOCD. +11:25 < kbingham> But it's a desire rather than a task at present. +11:25 < marex-cloud> wsa_: roger +11:25 < geertu> OK. Then I think we can continue with I/O? +11:26 < geertu> wsa_: The mic is yours +11:26 < wsa_> oh, one question: any estimate for SDHI PFC settings for Salvator-XS? +11:26 < dammsan> geertu: if no further update is needed for additional tasks then i will submit, is that ok? +11:27 < geertu> wsa_: PFC for I/O devices is typically handled by the person doing the I/O device. Use BSP as a reference. +11:27 < wsa_> geertu: i see. ok, thanks +11:27 < geertu> dammsan: Fine for me (I had no feedback from Niklas and Simon?). +11:27 < dammsan> good, thanks +11:28 < neg> geertu: I'm sorry my mail that stated I was happy with the draft is stuck in my draft folder for som reasnon. Sorry about that +11:28 < geertu> neg: No problem, as long as it was a happy response ;) + +After Lunch/Dinner + +14:09 < geertu> dammsan: I take it you're the expert on early (boot-time wise) R-Car Gen2 hacks? +14:10 < dammsan> yes i believe so +14:10 < geertu> Or not, from the lack of comments on my patches? ;-) +14:10 < dammsan> hehe, i am ducking too much +14:11 < dammsan> you were talking about arch timer? +14:11 < geertu> and generic counter +14:11 < dammsan> i have little knowledge about the latter +14:11 < dammsan> did it use a different name earlier? +14:12 < dammsan> there is global timer too +14:12 < geertu> not AFAIK +14:12 < dammsan> i recall +14:12 < dammsan> what is it? +14:12 < jmondi> I'm bothering neg in private now, if my point on device tree shuffling was the only one to discuss about this afternoon +14:12 < dammsan> some sort of timer i guess? per-cpu? +14:13 < geertu> I think it's the real counter behind the arch timer +14:14 < geertu> It has the CNTFID0 and CNTCR register, being accessed in rcar_gen2_timer_init() +14:14 < dammsan> ok i see. different from arch timer and twd +14:14 < geertu> If it doesn't run, arch timer also doesn't work +14:14 < dammsan> i see +14:14 < dammsan> i guess that code was developed without global timer in mind +14:15 < dammsan> focus on arch timer instead +14:15 < geertu> unlike arch timer it's memory mapped +14:15 < geertu> using a hardcoded address +14:16 < geertu> The good news is that Mark Rutland doesn't want it to have DT bindings, nor to appear in DT +14:16 < geertu> ;-) +14:16 < dammsan> ok, but how is that different from say GIC +14:16 < geertu> However, according to him it should be handled in the boot loader/firmware +14:16 < dammsan> it is not preset at base_addr + offset? +14:16 < geertu> or a bootloader shim +14:17 < dammsan> is it available on single code cortex-a9? +14:17 < dammsan> s/code/core/g +14:17 < geertu> /* Remap "armgcnt address map" space */ +14:17 < geertu> base = ioremap(0xe6080000, PAGE_SIZE); +14:18 < geertu> I don't know. Perhaps not. We only need to play with it on Gen2, i.e. A15/A7 +14:18 < dammsan> ok, however the upstream global timer driver mentions cortex-a9 +14:18 < dammsan> so we may be able to use it on rz/a1 +14:18 < dammsan> but anyway +14:19 < geertu> It's not global timer, but generic counter' +14:19 < dammsan> i think that 0xe6080000 is base address + 0x80000 +14:19 < dammsan> where base happens to be 0xe6000000 on r-car gen2 +14:20 < dammsan> probably matches gic and other arm peripherals +14:20 < dammsan> i may be wrong +14:20 < dammsan> but usually there is a single base address for the arm stuff +14:20 < geertu> GIC is @f1001000 +14:20 < dammsan> hm +14:20 < dammsan> arch timer same? +14:20 < geertu> See R-Car Gen2 Section 9.2 +14:21 < geertu> No, arch timer uses mrc/cr asm, not mmio +14:21 < geertu> It refers to DDI0406C2c_arm_architecture_reference_manual Appendix D.3 Counter module control and status registers. +14:21 < geertu> but it's App. D.5 in later revisions of that document +14:21 < dammsan> right, and we are not using twd on those more recent 32-bit socs +14:22 < geertu> BTW, it's also mentioned in the Gen3 docs +14:22 < geertu> Both say: Set bit 0 in CNTCR to 1 to start the Generic Counter when the CPU is placed in the secure mode. +14:23 < geertu> which is not done on Gen2 boards. +14:23 < dammsan> interesting +14:24 < dammsan> i recall that one of the timer workarounds were related to undocumented clock frequency dividing based on the MD pins +14:24 < dammsan> maybe that is different than the issue you are mentioning +14:24 < geertu> Yes, the frequency depends on the crystal (H2/M2) or ZS clock (V2H/E2), which is somehow related to MD settings (set MD according to crystal) +14:25 < geertu> U-boot inits it on iMX in arch/arm/imx-common/syscounter.c +14:25 < geertu> We can fix U-Boot, but I guess we needs backwards-compatibility with whatever is in use +14:27 < dammsan> i think we want to avoid breaking stuff +14:27 < geertu> Indeed. +14:28 < geertu> So either we keep the existing code, or move it to a "bootloader shim" +14:28 < geertu> As it doesn't involve DT, I think the easiest is to keep the existing code ;-) +14:28 < dammsan> i recall that some data sheet mentioned that the arch timer was supposed to run on say 13MHz fixed but in reality the MD pin setting divided it in two or so +14:29 < geertu> Yes, the register is programmed for 13 MHz, while reality is 10 or 32.5 MHz +14:29 < geertu> Aha, u-boot:include/configs/salvator-x.h:#define COUNTER_FREQUENCY 0xFE502A /* 16.66MHz from CPclk */ +14:29 < dammsan> ok that makes sense +14:29 < geertu> The current code probably breaks virtualization +14:30 < dammsan> i guess developing a parallel workaround in that "bootloader shim" doesnt hurt +14:30 < dammsan> especially if it can run in parallel with the existing code +14:30 < dammsan> then we can phase out the in-kernel workaround over time +14:30 < dammsan> also fixing u-boot makes sense +14:31 < geertu> Any examples of "bootloader shim" out there? +14:31 < dammsan> not sure myself +14:31 < dammsan> i don't even know what it is +14:33 < dammsan> my feeling is that this kind of workaround should be in the CPG or MD-pin code +14:33 < geertu> AFAIK it's something that runs after the bootloader, and before Linux +14:33 < dammsan> under compressed/? +14:33 < dammsan> but it is possible to boot vmlinux too, right? +14:34 < geertu> I think even separate from the kernel +14:34 < dammsan> hm, i'm not too fond of throwing stuff over the fence and breaking things just for the sake of cleanups +14:35 < geertu> me neither +14:35 < dammsan> also we used to boot linux directly from the reset vector +14:35 < dammsan> this disappeared with the multi-arch migration +14:36 < geertu> Documentation/arm64/booting.txt has requirements for the state before entering Linux +14:36 < geertu> - Architected timers +14:36 < geertu> CNTFRQ must be programmed with the timer frequency and CNTVOFF must +14:36 < geertu> be programmed with a consistent value on all CPUs. If entering the +14:36 < geertu> kernel at EL1, CNTHCTL_EL2 must have EL1PCTEN (bit 0) set where +14:36 < geertu> available. +14:36 < dammsan> but if we could have a board-specific compressed header then that would be fine +14:36 < dammsan> it does not say "correct frequency" =) +14:37 < dammsan> even if i would have preferred that +14:37 < dammsan> and this is on 32-bit linux, right? +14:37 < geertu> Yes +14:37 < geertu> 32-bit +14:38 < dammsan> having a well documented state of boot is not a bad thing though +14:38 -!- horms [~horms@2001:470:fe2c:302::1000] has joined #periperi +14:38 < dammsan> but i doubt that existed on 32-bit arm? +14:39 < dammsan> we could argue that we want to boot RZ/A1 directly into linux +14:39 < dammsan> and because of that need to perform various setup early on +14:39 < dammsan> of course it can be argued that the code should be somewhere else +14:40 < dammsan> i guess it is up to the maintainers in the end +14:40 < geertu> RZ/A1? +14:40 < horms> coming in late here, but we could revive the early-boot linux work that magnus and I did some years ago to strengthen our hand if it makes sense +14:40 < geertu> This is al about R-Car Gen2 and RZ/G1 +14:40 < dammsan> that is also 32-bit cortex-a9 +14:41 < dammsan> yeah i understand, just thought it may be useful on cortex-a9 too, but perhaps that was the global timer instead +14:41 < dammsan> horms: yeah something like that may make sense +14:42 < dammsan> it is not so easy to go against the desire of the arm guys though +14:43 < dammsan> for the timers i would have preferred to use CCF and then MD pin detection for the clock frequency workaround +14:43 < geertu> dammsan: All of that runs way too late, I think +14:43 < dammsan> but instead a static DT property was preferred, or preprogrammed value +14:43 < dammsan> that might be so +14:43 < geertu> The arch timer frequency can be put in DT. That also works. +14:43 < geertu> However, it's deprecated, and breaks virtualization +14:44 < dammsan> doesn't it also create mismatch if the MD pin setting is different from DT? +14:44 < dammsan> so it seems dynamic to me +14:44 < geertu> dammsan: Yes, but if you change MD, you should change the crystal, too +14:45 < dammsan> so the existing code is working around an incorrect setup? +14:45 < geertu> But we stopped using MD to derive the arch timer frequency a long time ago. These days we look at the extal clock-frequency in DT +14:46 < geertu> On V2H/E2, the value is hardcoded. It's ZS/8, but ZS must be fixed at 260 MHz anyway (unless you e.g. change the crystal without updating MD, but that's out-of-spec) +14:47 < dammsan> hm... +14:47 < dammsan> so there is no divider in the hardware? +14:48 < geertu> Somewhere there is, but it's not programmable: arch timer freq is either extal/2, or zs/8 +14:48 < dammsan> and that selection is done run-time, or via static DT configuration? +14:49 < dammsan> sorry for being a bit unclear =) +14:50 < dammsan> just wondering if we could solve multiple issues by assuming the clock to be more dynamic +14:51 < geertu> dammsan: based on SoC compatible (H2/M2 use extal/2, V2H/E2 use ZS/8) +14:51 < dammsan> ok that makes sense +14:51 < dammsan> thanks! +14:52 < dammsan> so what to do? =) +14:53 < geertu> I'll have a look to see if the shim is doable +14:54 < dammsan> is this the only workaround that is left for 32-bit arm? +14:54 < dammsan> for our socs i mean? +14:54 < dammsan> if we could move multiple things to that shim then that would be nice +14:54 < geertu> The other one is the CNTVOFF thingy +14:55 < geertu> We currently do that on the boot CPU of CA7 systems only. +14:55 < geertu> E2 needs it on all CPU cores. +14:56 < shimoda> oops, i kept to join this, but i worked other things :) i go home now, byebye! +14:56 -!- shimoda [~shimoda@relprex3.renesas.com] has quit [Quit: WeeChat 0.4.2] +14:56 < dammsan> i see +14:56 < geertu> No idea if shims can easily run on all CPUs. Probably not, as it involves actually booting them. +14:56 < geertu> However, Marc Zyngier doesn't seem to be opposed to doing it in the kernel. +14:57 < dammsan> the tricky part is that the secondary cpu cores come up from reset +14:57 < dammsan> so we need to setup stuff for those anyway +14:57 < geertu> He did say we also need it on CA15, as A15/A7 are very similar, and that it's sheer luck it worked for us. +14:57 < dammsan> yes that is inline with what i've seen +14:57 < dammsan> the power-on-reset value happened to be correct on CA15 +14:58 < dammsan> or at least not wrong +14:58 < dammsan> or correct enough to boot =) +14:58 < geertu> Always doing these few asm instructions when a CPU core boot won't delay it too much... +14:59 < dammsan> thats right +14:59 < dammsan> there are also cache workarounds needed for secondary cpus +14:59 < geertu> BTW, how can you boot from CA7 on (remote) lager? +14:59 < geertu> The cache workarounds may be handled by generic code +14:59 < dammsan> maybe these days +15:00 < dammsan> they used to be local code in some bsp +15:00 < dammsan> eventually made it into upstream and then got consolidated i think +15:00 < dammsan> would you like to boot CA7 on lager? +15:00 < geertu> So if we don't have to describe the gneric counter in DT, the only piece missing is ICRAM for SMP bringup (patches sent) +15:01 < dammsan> only piece missing for what? +15:02 < geertu> Having everything described in DT, so we can boot without relying on any hardcoded address in the kernel +15:02 < dammsan> ok i see +15:02 < dammsan> sounds good to me! +15:02 < geertu> I want to have a single flag day for all of that for Gen2 (incl.

If so how many beds do we need? +11:36 < morimoto> but should we at 1st ? +11:37 < pinchartl> morimoto: the meetings will start on the 4th. it depends how long you need to get adjusted to jetlag ;-) +11:37 < morimoto> Hehe :) +11:37 < pinchartl> neg: I would like to +11:38 < morimoto> If we can have extra meeting before 4th, it can be good reason to escape from office for us :) +11:38 < Marex> heh +11:39 < pinchartl> I'm sure we could organize a meeting before the 4th if needed :-) +11:40 < neg> pinchartl: so that is you, kbingham, uli___, geertu, jmondi, wsa, Marex, simon and me => 9 ppl or am I forgeting someone? +11:41 * Marex is invited to the megaparty ? wow, I'm flattered +11:41 < pinchartl> I think that's it. however, some of us might prefer staying at a hotel, you would have to ask +11:41 < geertu> I don't mind a house +11:41 < geertu> I don't mind a hotel +11:41 < neg> ofc just looking for the upper limit to be able to browse the options +11:42 < pinchartl> geertu: there might be no pig this time +11:43 < neg> :-( +11:44 < geertu> pinchartl: As long as there's a pig in the main house, Morimoto-san will be happy +11:44 < pinchartl> neg: when do you plan to fly back ?

+11:48 < pinchartl> sounds good to me +11:48 < pinchartl> Kieran will likely leave on the 8th +11:48 < geertu> pinchartl: me too +11:49 < dammsan> me too +11:49 < neg> So since ppl intend to show up erlier should we aim to move the IO meeting from the 8th to some other day? +11:49 < pinchartl> geertu: and you will arrive on Monday the 4th, right ? +11:50 < pinchartl> neg: I'd rather not move the social day to Friday though +11:50 < dammsan> same here +11:50 < geertu> pinchartl: Correct (still to book flights) +11:50 < Marex> geertu: damned iberia is oneworld :/ +11:51 < dammsan> can we host i/o meeting in other airbnb place? +11:51 < pinchartl> dammsan: I think we should be able to +11:51 < neg> If we managed to find one I'm sure that is possible +11:52 < dammsan> my guess is that 9 ppl needs two more airbnb probably +11:52 < dammsan> unless you want to share a single shower +11:53 < dammsan> the map browsing feature of airbnb is pretty good btw +11:53 < dammsan> i recommend to check cancellation policy, the strict one is pretty strict imo +11:53 < neg> a qucik search suggest there are ~2 options near by that have >= 9 beds but yes there might be other constrains such as showers (but the sea is so close...) +11:54 < pinchartl> neg: maybe we should aim for 2 places +11:54 < dammsan> usually number of baths are kind of limited. also many double beds +11:54 < dammsan> think 12ppl place turns into 4ppl +11:55 * neg never used airbnb so good point about checking the cancellation policy +11:55 < dammsan> if you are tight on space then there most likely is an unused twin bed in my room +11:56 < dammsan> but we are a tad low on bath options so i prefer not to push it more than necessary +11:58 < neg> cheking the old mail thread it looks like everyone is attending but Marex who provided no prefrences on dates and Simon who did not prefere the dates but not sure if he made it work or not since, anyone know? +11:59 < dammsan> i think simon is fine +11:59 < geertu> Yeah, I talked to him last week, and he is planning to attend +12:04 < dammsan> Marex: how difficult is it to work on the RPC? can you do it w/o further docs? +12:08 < Marex> dammsan: I'd have to check that, but probably yes +12:09 < Marex> dammsan: I would need a few hours to familiarize myself with the hyperflash part +12:09 < Marex> dammsan: the RPC itself is documented and there is example code too +12:09 < dammsan> i think you should go ahead and scratch that itch +12:09 < Marex> dammsan: OK, thank you +12:09 < dammsan> worst case if renesas prefers not to use it then we can keep it disabled +12:10 < Marex> dammsan: right +12:17 < dammsan> pinchartl: i booked the airbnb meeting place from the 2nd. was thinking of exploring bilbao before that. +12:18 < dammsan> but if more people arrive in san sebastian earlier then i'm happy to be there instead +12:20 < pinchartl> dammsan: I'll fly to San Sebastian, but I could then move to Bilbao or somewhere else +12:20 < dammsan> its just around the corner +12:21 < dammsan> Bilbao is supposed to have a bit more of museums if i understand it correctly +12:22 < dammsan> according to my guide books busses to san sebastian tend to go via bilbao by default, but it may vary with airport and timing +12:23 < pinchartl> the question is, where are the good restaurants ? :-) +12:23 < dammsan> i got a michelin guide book but it is in spanish =) +12:24 < dammsan> still easier than japanese +12:24 < geertu> spanish is a (far) descendant of greek? +12:25 < dammsan> according to "lonely planet pocket bilbao and san sebastian" you should book months ahead +12:26 < pinchartl> indeed, there's a risk of that +12:26 < dammsan> geertu: not sure, but many words seem easy to understand to me +12:26 < pinchartl> there's clearly no way we'll fit the whole crowd around the same table anyway +12:26 * pinchartl is off for lunch, I'll be back later +12:26 < dammsan> probably so +12:28 < dammsan> we should be able to eat a lot of pintxos at least! +12:28 < geertu> dammsan: french, spanish, italian, latin, ... all the same ;-) +12:28 < dammsan> txoko seems interesting too +12:28 < dammsan> indeed =) +12:34 * geertu lunchtime +12:50 * morimoto will go back to lovely home +12:50 < morimoto> I hope someone can put this chat log to Wiki page somehow diff --git a/wiki/Chat_log/20170803-io-chatlog b/wiki/Chat_log/20170803-io-chatlog new file mode 100644 index 0000000..a315dd6 --- /dev/null +++ b/wiki/Chat_log/20170803-io-chatlog @@ -0,0 +1,107 @@ +09:59 < neg> wsa_: congrats on the SD issue fixes :-) +09:59 < wsa_> thanks :) +09:59 < wsa_> let's wait for Simon's test first, though +10:00 < wsa_> although I'm somewhat optimistic since my pretty stubbto SanDisk cards works now +10:00 < wsa_> sttubborn +10:00 < pinchartl> hi Wolfram +10:00 < wsa_> well, you know what i mean ;) +10:02 < wsa_> shall we start?

+11:03 < dammsan> yeah +11:04 < dammsan> so if you want to make use of your slots then i suggest that each guy and/or the group leaders suggest some activities =) +11:05 < pinchartl> is there any request you're aware of from Renesas ? +11:05 < pinchartl> or from you ? :-) +11:06 < dammsan> for m/m i care about consistent support level in mainline +11:06 < pinchartl> what do you mean by that ? +11:06 < dammsan> so perhaps salvator-x and xs and ulcbs may be in not-so-onsistent state +11:06 < dammsan> i mean that if we for instance enabled MMC on one board we should do it on other boards as well +11:06 < dammsan> not sure what the state is for m/m +11:07 < dammsan> with video out and video-in +11:07 < pinchartl> yes, I agree +11:07 < pinchartl> should we start buying ULCBs ? +11:08 < dammsan> i think that makes sense yes +11:08 < dammsan> you are free to use my boards via remote access too +11:08 < pinchartl> for display it's better to have local access +11:08 < pinchartl> can hardware costs for ULCBs be charged to Jinso ? +11:09 < dammsan> i got some converters so i should be able to use HDMI-out via the Adder IPEPS VNC magic too +11:09 < dammsan> i think it should be doable, but may i propose that we associate the cost with additional tasks? +11:09 < pinchartl> sure +11:09 < dammsan> if you can figure out what is missing then we can make sure to provide funding for the required h/w +11:10 < pinchartl> I suppose we should target both the H3SK and M3SK ? +11:10 < dammsan> also the never-ending vin-for-rcar-gen3 =) +11:10 < dammsan> i think so +11:10 < wsa_> dammsan: good news, SDHI/MMC enablement for D3/XS was planned for 9/M together with the drive_strength task +11:10 < dammsan> just make sure to get an H3 with ES2. +11:11 < dammsan> wsa_: good!! +11:12 < dammsan> then we have D3 and V3M as well, but those need to wait a bit i think +11:12 < pinchartl> thank you +11:12 < dammsan> thanks +11:13 < pinchartl> regarding additional tasks, if anyone has one (or more) specific task he wants to work on, please let me know +11:13 < wsa_> ditto +11:15 < pinchartl> (buying the H3SK might not be that easy) +11:15 < dammsan> you can begin with M3 perhaps +11:15 < pinchartl> no stock at digikey, avnet europe doesn't even list it on their website +11:15 < pinchartl> same for M3SK :-) +11:15 < dammsan> i've got both H3 ES1 and ES2 boards +11:16 < dammsan> if anyone wants to go down the route of remote access +11:16 < pinchartl> where did you buy them ?

+11:20 < dammsan> it should be fairly straight forward i believe +11:20 < pinchartl> it's just integration until we run into issues :-) +11:21 < dammsan> true +11:22 < pinchartl> and I'll assume we'll need ULCBs for Kingfisher development too +11:22 < pinchartl> so it makes sense to plan for that +11:23 < pinchartl> does Kingfisher support both H3SK and M3SK ?

+10:57 < wsa_> Gen3 docs say "HSSCR can always be read from and written to by the CPU." +10:57 < pinchartl> from any point of view :-) +10:58 < pinchartl> after the read-only register, the write-only register, we have the don't-access-only register +11:00 < wsa_> so, the other issue is SDR104 on Gen3 +11:00 < geertu> on H3 ES2.0? ;-) +11:00 < wsa_> (if there are not more ideas on the HSSCR register) +11:00 < wsa_> enabling ES2.0 is also somewhere on my todo-list +11:01 < wsa_> one of the tasks I'd really like to give away, but in my book, this is a base-task, not an additional task +11:02 < wsa_> this is why I'd like to discuss the status-quo in SanSeb +11:02 < wsa_> so, SDR104 memory cards now work fine on H3 ES1.* and M3-W 1.0 +11:03 < wsa_> it is the SDIO card which has problems in some slots +11:03 < wsa_> at high speeds +11:03 < wsa_> I think the fact that the line length is ~23cm instead of 10cm might have an influence +11:04 < wsa_> hard to test +11:04 < wsa_> resoldering in SanSeb was also kind of shot down :) +11:05 < wsa_> I wonder where is the line of not enabling-SDR104 because of some setup +11:05 < wsa_> I don't want to enable it now +11:05 < wsa_> ES2.0 testing should also happen and way more testing in SanSeb +11:05 < wsa_> but still +11:05 < pinchartl> wsa_: desoldering such connectors is pretty difficult. a soldering iron isn't the best tool for the job +11:05 < geertu> Can't the driver/subsystem downgrade the feature set if errors are detected? +11:07 < wsa_> on the mmc core layer, could be +11:07 < wsa_> dunno if a driver can request that if e.g. loading firmware fails +11:08 < wsa_> i'd guess if the core notices a problem it will schedule a retune +11:08 < geertu> And if retune fails? +11:09 < wsa_> i expect it to go down with the speed, but i haven't checked +11:10 < wsa_> so far, our tuning only failed because of stalled HW +11:10 < wsa_> but we fixed that +11:12 < wsa_> well, looks like this is a question for SanSeb, too; when we also have more data +11:13 < wsa_> i think that's it for io +11:13 < wsa_> unless you have something to add? +11:13 < geertu> I have one more comment +11:13 < wsa_> sure +11:13 < geertu> About shifting the UART sampling point: This can increase accuracy for serial +11:13 < geertu> speeds that are too much off, cfr. 92a0574867f3329c ("serial: sh-sci: Add +11:13 < geertu> support for SCIFA/SCIFB variable sampling rates"). +11:14 < geertu> If the actual speed differs more than a few % from the requested speed, it fails. +11:14 < geertu> Changing the sampling point can fix that. +11:16 < uli___> i'm looking into quantifying that effect in practice +11:16 < uli___> my current idea is to plop a 57.6 kHz square wave into an uart +11:16 < uli___> and then tweak the frequency until the received pattern is not repetitive any more +11:17 < uli___> and then check if pushing the sampling point can improve the margin +11:17 < uli___> dunno if that works, i'll see once i get my equipment +11:18 < geertu> I had a simpler test method when doing the variable sampling rates +11:18 < geertu> Just configure a speed that cannot be done exactly +11:18 < geertu> and see how it receives garbage. +11:19 < uli___> don't you need two ends for that, with differing imprecisions? +11:19 < geertu> USB serial adapters (e.g. FTDI) can usually do all standard rates. +11:20 < geertu> Renesas SCIF ports always can't, with the supplied clocks +11:20 < geertu> E.g. APE6EVM couldn't do 460800 bps before the aforementioned patch +11:22 < geertu> I think SCIFA on Gen2 still can't do 1500000 bps +11:22 < geertu> Perhaps also not 460800 +11:23 < uli___> frankly, i'm atm more concerned if that functionality in the hscif actually works at all... +11:24 < wsa_> i understand that +11:24 < wsa_> same here +11:24 < geertu> It's not that difficult to find out. +11:25 < geertu> Try all standard rates up to 4 Mbps, and see which fails. +11:25 < wsa_> if we get feedback from renesas next week, this is kinda late for setting up an add. task +11:25 < geertu> Then try all possible sampling points, and see if it helps +11:25 < wsa_> first start would be to see if you can actually change bits in the register ;) +11:26 < uli___> i'll look into it +11:27 < wsa_> for completeness, the planned IO tasks for Q3/2: +11:27 < wsa_> Simon - IP csum offloading for EtherAVB +11:27 < wsa_> Uli - (hopefully) this sampling point adaption for SCIF +11:28 < wsa_> Wolfram - DT bindings for SD/MMC drive strength settings (and side-effect: SDHI ES2.0 enabling) +11:28 < wsa_> note: not PFC drive strength +11:29 < wsa_> this is a command sent to the controllers on the other side +11:29 < wsa_> are we done?

+09:21 < geertu> uli__: What do you mean? Can't you just recalculate? +09:22 < uli__> yes, but that makes little sense; if you have a device connected that deviates, it will not deviate the same way at different baud rates +09:22 < uli__> so scaling is not helpful +09:22 < uli__> resetting is even worse, it's a biting-the-carpet bug generator for userspace +09:23 < geertu> uli__: Ah, so the goal is to accomodate an off device at the other side. +09:23 < uli__> yes +09:23 < horms> shimoda: assuming the problem was introduced in v4.14 then fixing it there seems to be a good idea. and providing a simple fix/work around sounds appropriate if a full fix is too invasive. +09:23 < geertu> Then you need a way to communicate the other side's rate to the driver => sysfs? +09:23 < uli__> exactly +09:23 < geertu> Or ioctl. Ugh +09:24 < uli__> and that gregkh doesn't like new sysfs attributes doesn't help either +09:24 < geertu> But it can also be used if the local scif cannot support the exact requested rate, right? +09:25 < shimoda> geertu: you're request means what of_dma_configure() output the message? dev_dbg(dev, "device is%sbehind an iommu\n", iommu ? " " : " not "); +09:25 < geertu> shimoda: I mean if the MMC driver can figure out if the IOMMU is used by looking at its dma_ops +09:26 < geertu> I believe of_dma_configure() is already called anyway. +09:26 < shimoda> horms: thank you for your comment! I will add such document and submit v2 patch +09:26 < uli__> geertu: that is also possible, but it's not the use case i have looked into +09:26 < geertu> uli__: OK. But it's something that doesn't rely on sysfs ;-) +09:27 < geertu> So for now you could calculate sampling point based on requested rate vs. scif-supported rate. +09:28 < geertu> Later it can be extended to remote-supported rate vs. scif-supported rate +09:28 < uli__> that would probably work +09:28 < geertu> The latter of course depends on discussing with Greg and friends about a good way to configue remote-supported rate +09:28 < geertu> Does that make sense? +09:29 < uli__> i think it does +09:30 < wsa_> shimoda: was my mail about your IIC requests helpful to you? +09:31 < shimoda> geertu: i don't think dma_ops is useful to figure out if the iommu ise used or not because dma_ops only has function pointers. So, it is diffcult to use on multiple arch. +09:32 < shimoda> wsa_: I'm sorry, i need to read your comment more about stop condition. +09:32 < geertu> shimoda: OK. Then we have to bring up to Konrad that we can use his suggestion as a temporary workaround, but that it doesn't solve the full problem (i.e. it limits mapping size if the device uses the IOMMU) +09:33 < wsa_> shimoda: i see, no worries. Please ask if there are still questions or if it is more urgent +09:33 < horms> can you use dma_ops like this? if (dma_ops == renesas_sdhi_sys_dmac_dma_ops) ... +09:34 < shimoda> geertu: ok. you means we should use his suggested api on the sdhi driver instead of hardcoded value of max_blk_size? +09:35 < geertu> shimoda: Yes. If swiotlb_set_max_segment() returns non-zero, we should use the returned value. +09:35 < shimoda> wsa_: i got it. thanks! +09:35 < shimoda> geertu: i got it! +09:35 < geertu> shimoda: Optimization for IOMMU can be done later +09:35 < geertu> Correctness first ;-) +09:35 < wsa_> swiotlb_max_segment() +09:36 < wsa_> not swiotlb_set_max_segment +09:36 < geertu> wsa_: Thanks, copy-and-pasted the wrong fucntion +09:36 < geertu> s/fucntion/function/ +09:36 < wsa_> :) +09:36 < wsa_> ok, i think that was it for io? +09:37 < neg> One question is thermeal driver support IO or Core ? :-) +09:37 < geertu> neg: If you want to control e.g. CPUFreq, it's core +09:37 < geertu> neg: If it's just about measuring temperatures, it's I/O +09:38 < geertu> wsa_: Do you agree? ;-) +09:38 < wsa_> I was about to write the same thing, yes +09:38 < wsa_> :) +09:38 < neg> OK I'm thinking about thermal readig of temps for V3M, so then I guess it's IO :-) Do we have a request/plan for V3M support as it looks like this will be different from rcar_gen3_thermal +09:39 < wsa_> neg: I didn't get anything like that yet +09:40 < wsa_> I didn't get any request for V3M yet +09:40 < neg> wsa_: OK I just wanted you (or Geert if it where Core ;-) to be aware of the hardware difference that is all :-) +09:40 < wsa_> ok, thanks! +09:41 < wsa_> so, it's core time now... +09:41 < wsa_> thanks guys! happy hacking... +09:41 < geertu> wsa_: Thank you! diff --git a/wiki/Chat_log/20171019-mm-chatlog b/wiki/Chat_log/20171019-mm-chatlog new file mode 100644 index 0000000..9d45391 --- /dev/null +++ b/wiki/Chat_log/20171019-mm-chatlog @@ -0,0 +1,142 @@ +Multimedia-chat-meeting-2017-10-19 + +10:11 < pinchartl> thank you. let's get started with multimedia then +10:11 < pinchartl> let's see who's here +10:11 < pinchartl> we have jmondi +10:11 < pinchartl> dammsan: +10:11 < pinchartl> morimoto: +10:11 < pinchartl> neg: +10:11 < pinchartl> uli__: +10:11 < pinchartl> and possibly kbingham_ lurking +10:11 < wsa_> i gotta run, cya guys! +10:12 < pinchartl> first topic, status check for multimedia tasks +10:12 < pinchartl> jmondi: you reported last, please start :-) +10:12 < jmondi> Marex: why are you jumping between this and #renesas-soc room?

I have binaries available for M3/H3 ULCB and Salvator-X (only H3 ES2.0+ supported) +10:00 < Marex> or well, even better, you can build the whole stuff yourself ... +10:00 < dammsan> Marex: i want automated updating via script somehow +10:00 < geertu> And M3-W Salvator-X? +10:01 < Marex> geertu: what's 7796 salvator-x , right ? I didn't test, but should work, wanna try ? :-) +10:02 < Marex> geertu: wait, I tried 7796 salvator-x and 7795 salvator-xs ... +10:02 < geertu> Marex: Good, that's what I have ;-) +10:02 < Marex> dammsan: of uboot ? that can be done already (read: I use that to make my life easier), although it's undocumented, just like unlocking the RPC, for obvious reasons +10:03 < Marex> dammsan: I can documented that internally somehow though +10:04 < dammsan> neg: tack - behover tva separata men kan separaera sjalv sa inga problem +10:05 < geertu> Looks like we're finished. +10:05 < geertu> Thanks for joining, and have a nice continued day! +10:06 < dammsan> Marex: Documenting stuff is always good. Knowledge how to detect which version of various boot loader stack that are installed would be nice to document too +10:06 < horms> Thanks Geert! +10:06 < pinchartl> I'll give everybody a few minutes for a restroom break and we can then start with multimedia +10:06 < Marex> dammsan: we have "version" command and the version is printed upon boot too :-) +10:07 < Marex> dammsan: where are you aiming with this, some sort of update automation ? +10:07 < geertu> kbingham: Will you join the activities on Friday before FOSDEM? (cfr. "Meeting before FOSDEM" at 8:33 your time) +10:07 < Marex> dammsan: might be better to have some sort of "update_uboot" script in U-Boot, which you run to reinstall everything +10:08 < Marex> dammsan: hmmm, maybe you could deliver the update as a fitImage, containing all the components ... hmmmmm +10:08 < dammsan> Marex: I am thinking of more components than just U-bbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbboot, butnks!! +10:08 < Marex> dammsan: feels like we're reinventing the UEFI update capsule +10:08 < dammsan> maybe so +10:08 < dammsan> automation would be nice to have +10:08 < Marex> dammsan: you mean updating IPL and U-Boot or even more stuff ? +10:09 < dammsan> yeah +10:09 < wsa_> gotta run +10:09 < wsa_> cya! +10:09 -!- wsa_ [~wsa@p54B3351E.dip0.t-ipconnect.de] has quit [Quit: ...] +10:10 < pinchartl> alright +10:10 < kbingham[m]> geertu: I'm planning to bring Hugo and Keri to Brussels for a trip and Hugo's first plane ride.

If this is a high priority task - then I'll make time - but otherwise this will be a new year task for me. +10:28 < neg> morimoto`: no, it's part of VIN Gen3 patches which is not yet upstream +10:29 < kbingham> It's probably not a long task ... +10:29 < morimoto`> kbingham: no problem. it is not a high priority. I just asked +10:29 < pinchartl> kbingham: can we say for the next meeting then ? (9th or 11th, pending geertu's answer) +10:29 < kbingham> morimoto`: Ok thanks - +10:29 < neg> morimoto`: but the fault is also introduced by erlier versions of the same patch-set, so the fault have never been present upstream +10:29 < kbingham> pinchartl: Yes, I would hope January is achieveable :) +10:29 < pinchartl> thank you +10:30 < morimoto`> neg: OK, sounds nice.

I will not attend ELC this year +10:45 < kbingham> I believe the apartment is €180 per night. +10:45 < pinchartl> so that's 45€ / person +10:46 < morimoto`> pinchartl: Good question, and difficult to say +10:46 < morimoto`> It seems we can't goto ELC too, at this point. but not sure +10:47 < pinchartl> do you have more information about those budget cut ? does it affect other things than travel ? how long is it expected to last ? +10:47 < jmondi> morimoto`: what's happening? are they trapping in you in Japan this year? +10:48 < morimoto`> In Renesas side, our group were changed. Then, budget was changed too. +10:48 < morimoto`> I don't know detail, but, it seems some kind of confusable things happen +10:49 < morimoto`> I can say this is paper work issue +10:49 < pinchartl> so there's no need for all of us to start looking for a new job today ? :-) +10:49 < morimoto`> pinchartl: no problem: ) +10:49 < pinchartl> :-) +10:50 < morimoto`> EuroPeri member are very important for us +10:50 < pinchartl> JapanesePeri is very important for us too :-) +10:50 < neg> Ohh and I already sent out my resume to McDonalds ;-) +10:50 < kbingham> neg: You're not qualified to work at McDonalds. .. you don't have the required skill set :) +10:51 < neg> kbingham: I know, I was hoping for som on-site traning on burger flipping +10:51 < jmondi> morimoto`: new fight with paperwork guy ahead?

+10:53 < jmondi> we should get there on Sunday then +10:53 < neg> pinchartl: I also plan to arrive on Sunday +10:54 < jmondi> 28th then! +10:55 < morimoto`> jmondi: they have very hard stone head... +10:55 < pinchartl> next topic, additional tasks for 2018 Q1 +10:56 < pinchartl> are there tasks you would like to work on in particular ?

+11:00 < jmondi> pinchartl: I have received a D3 I assume for VIN parallel input support +11:00 < uli___> what exactly does "jtag support" mean? +11:01 < pinchartl> kbingham: that question is for you +11:01 < kbingham> uli___: The ability to use OpenOCD to connect and debug the kernel using GDB on Gen3 platforms +11:01 < pinchartl> jmondi: indeed, let me add that +11:01 < jmondi> and I feel like we should move gmsl in the open asap (as soon as rcar-vin and rcar-csi2 are mainlined) +11:01 < jmondi> we are actually piling too many pateches around +11:02 < pinchartl> there's also near-lossless compression upstreaming, I'll add that too +11:02 < jmondi> also, ov10635 driver should be separated from rdacm20, if we want to ease rdacm21 support... +11:03 < pinchartl> I'm not sure how to handle the rdacm21 yet +11:03 < pinchartl> but I agree about moving development to the open +11:03 < morimoto`> sorry, I need to go too. +11:03 < morimoto`> bye +11:03 -!- morimoto` [~user@relprex1.renesas.com] has left #periperi ["ERC Version 5.3 (IRC client for Emacs)"] +11:03 < pinchartl> morimoto`: no worries. have a nice evening +11:03 < pinchartl> dammsan: are you still there ? +11:04 < pinchartl> uli___: I think JTAG support means OpenOCD + gdb debugging for Gen3 +11:04 < pinchartl> jmondi: we need to have upstreamable code then :-) +11:04 < jmondi> pinchartl: and code that works, also +11:05 < pinchartl> that an upstreaming requirement for me :-) +11:05 < jmondi> I feel like after Feb. code camp that should be our first effore for gmsl.. everything is so fragile (see moving to v4.15-rc1, we still have not been able to achieve) +11:05 < kbingham> uli___: I would particularly like to be able to use it - I have already hooked up a a BusBlaster - and it can see the 'dap' on the coresight module - but can't get access to the CPU's yet. +11:05 < jmondi> s/effore/effort/ +11:05 < pinchartl> checking an older additional tasks list, there' also +11:05 < pinchartl> * DU interlaced modes support +11:05 < pinchartl> * VIN scaler +11:05 < pinchartl> * VIN TB/BT field support in continuous mode +11:05 < pinchartl> neg: or is that one complete already ? +11:05 < kbingham> uli___: If this is an area your familiar with - I would certainly be happy to hand the topic over to someone who knows more than me - I just want it to work :) +11:06 < uli___> i did that for kzm9g before... +11:06 < pinchartl> kbingham: what's the status of * ADV7482 CEC support ? +11:06 < neg> pinchartl: no VIN UDS scaler work not started, feels like the driver shuld be upstreamd first +11:06 < kbingham> pinchartl: Not yet done, and therefore also on that list :) +11:06 < pinchartl> neg: I meant TB/BT in continuous mode +11:07 < neg> pinchartl: VIN TB/BT in continuous mode would depend on the rework of the capture loop to not use single capture mode, which I hope to also be able to postpone to after Gen3 support is megred upstream +11:07 < pinchartl> neg: OK +11:08 < pinchartl> uli___: how about on your side, do e need more additional task for the GPU ? or is there something else you'd like to work on ? +11:09 < uli___> the jtag thing sounds good, actually +11:09 < pinchartl> I like it too, but it's a core task, so it has to be coordinated with Geert +11:09 < pinchartl> anything on the multimedia side ? :-) +11:09 < uli___> about the gpu, i'd like to finish the current task before i make up my mind about it +11:10 < pinchartl> when do you expect to finish it ? +11:10 < uli___> it's due on friday +11:11 < uli___> apart from that, dab/fm stuff sounds interesting, depending on the details +11:11 < kbingham> DAB/FM was just something I put on the list because I noticed there is some hardware somewhere in the R-Car to handle it. +11:11 < pinchartl> I don't know if it's a priority for Renesas, but we can certainly propose it +11:11 < kbingham> So I don't really know details beyond that. +11:14 < pinchartl> ok +11:15 < pinchartl> so I have a list of tasks that I will include in the report +11:15 < pinchartl> and we'll need to prioritize it, based on Renesas' feedback +11:16 < pinchartl> as neither Morimoto-san near Magnus seem to be here, I think we'll handle that through e-mail +11:16 < pinchartl> dammsan: still not available ? +11:16 < pinchartl> geertu: ping +11:18 < geertu> pinchartl: pong +11:19 < pinchartl> geertu: have we decided on whether the next meeting will be on the 9th or the 11th ? +11:20 < geertu> pinchartl: Not yet. wsa is unavailable on the 11th +11:20 < pinchartl> when do we decide ? :-) +11:21 < geertu> Does the 9th fit for all of you? +11:21 < pinchartl> works for me +11:22 < jmondi> that's fine! +11:22 < uli___> ok for me +11:22 < pinchartl> kbingham: neg: how about you ? +11:23 < kbingham> 9th works for me - probably better than the 11th for the same reasons as wsa :D +11:24 < neg> works for me +11:24 < pinchartl> kbingham: what's happening on the 11th ? +11:25 < pinchartl> OK, let's go for the 9th then +11:25 < kbingham> pinchartl: It's the day after the day :) +11:25 < kbingham> I think I recall both me and WSA share the same birthday +11:26 < geertu> kbingham: You expect a hangover on the 11th? +11:26 < pinchartl> but isn't the 9th the day before the day then ? +11:26 < kbingham> geertu: Nope - I try hard to avoid hangovers lately ... +11:26 < geertu> kbingham: Screaming Hugo + hangover = profit? +11:27 < kbingham> geertu: haha +11:28 < pinchartl> so I think this is all for the multimedia meeting today +11:28 < pinchartl> does anyone else have anything to add ? +11:28 < neg> I'm good, thanks all +11:29 < pinchartl> thank you all for attending diff --git a/wiki/Chat_log/20180109-core-chatlog b/wiki/Chat_log/20180109-core-chatlog new file mode 100644 index 0000000..1a9463f --- /dev/null +++ b/wiki/Chat_log/20180109-core-chatlog @@ -0,0 +1,76 @@ +Core-chat-meeting-2018-01-09 + +09:37 < geertu> Welcome to today's Core Group Chat Meeting +09:37 < geertu> Agenda: +09:37 < geertu> 1.

Status updates +09:37 < geertu> A) What have we done since last time +09:37 < geertu> Marek worked on HS200 for U-Boot again, assumed to go in after the 2018.01 +09:37 < geertu> release. +09:37 < geertu> Shimoda-san continued evaluation of the M3-N IPMMU HW. +09:37 < geertu> Simon fixed and merged Gen3 no-reg warnings, and addressed review for the +09:37 < geertu> Z/Z2/CpuFreq patches for Gen3. +09:37 < geertu> Ulrich sent ZG clock support for M3-W. +09:37 < geertu> Geert worked on additional tasks, prepared for the meeting before FOSDEM, +09:37 < geertu> sent clk and pfc pull requests, investigated a severe arm64 bug, tried +09:37 < geertu> Marek's new U-boot binary, and started looking into QEMU+kvm virtualization +09:37 < geertu> on arm64. +09:38 < geertu> (if anything is missing, please scream) +09:38 < geertu> B) What we plan to do till next time +09:38 < geertu> Marek will work on upstreaming Gen2 U-Boot rework. +09:38 < geertu> Shimoda-san will continue evaluating M3-N IPMMU HW. +09:38 < geertu> Simon will check Z2 clock handling for little CPUs on resume. +09:38 < geertu> Geert will do more virtualization work, try to build Marek's new U-Boot, +09:38 < geertu> and revisit in-kernel BD9571MWV DDR backup mode. +09:39 < geertu> C) Problems we have currently +09:40 < geertu> Simon lacks physical access to Lager board to set s2ram of little CPUs. +09:40 < geertu> Geert has issues with R-Car Gen3 firmware booting Linux in EL1 instead of +09:40 < geertu> HYP mode, precluding kvm. +09:40 < pinchartl> (I'll be back in 15 minutes, nothing to report for core) +09:40 < geertu> (in the mean time, Marek sent me firmware that should enable HYP mode, thx) +09:42 < geertu> Regarding Lager, does it need special firmware to enable 8 CPU cores? The one in Magnus' farm boots the big cores only +09:43 < shimoda> geertu: about 8 cores booting, i will ask someone +09:43 < wsa_> I can bring my Lager to Brussels if that helps and is not too late +09:44 < geertu> horms: Your particular issue is _local_ access to Lager, as the osdr wiki says you have a Lager (in Kobe)? +09:45 < horms> geertu: ues, that is correct +09:45 < horms> for paperwork reasons I left it there +09:45 < horms> I am wondering if anyone attending the Brussels session might bring a board +09:46 < wsa_> heh +09:46 * wsa_ waves again +09:46 < geertu> horms: Is the issue doing remote wakeup? You may get sufficiently far with /sys/power/pm_test +09:47 < horms> That is one issue. The other is upgrading the fw. +09:47 < geertu> OK, fw is more complicated +09:48 < horms> I can probably arrange to upgrade the fw somehow, f.e. by having the board sent to HQ, but its not entirely risk-free +09:48 < geertu> Sure, I understand +09:49 < geertu> So Wolfram's offer may be the simplest solution (depending on how much time is needed) +09:49 < geertu> Topic 2. Core additional tasks for Q1/2018 +09:49 < geertu> To the best of my knowledge, the following tasks have been issued for 2018 Q1 phase 1: +09:49 < geertu> - U-Boot for R-Car Gen2 DM and DT conversion (Marek) +09:49 < geertu> - QEMU+KVM on ARM64 and GPIO Pass-Through Prototype (Geert) +09:50 < horms> geertu: wsa_: yes, I think so. I can probably do preliminary testing in an hour or so.

+10:51 < neg> I have yet to book my flight but will update wiki once I have done so +10:51 < pinchartl> kbingham: taxi is an option, otherwise you can take the train to Brussels North, and from there metro 3 or 4 to La Bourse - Beurs. the metro stop is a 5 minutes walk to the apartment (one block and a half) +10:53 < pinchartl> regarding the GMSL code camp +10:53 < kbingham> pinchartl: That might be better than us bringing a car seat actually. +10:53 < pinchartl> kbingham: it's pretty easy yes +10:53 < pinchartl> about 15-20 minutes by train from the airport to Brussels North +10:53 < pinchartl> you can even buy the train ticket while waiting for your luggage at the airport +10:54 < kbingham> :D +10:54 < pinchartl> we need to plan for hardware availability +10:54 < pinchartl> I believe the following would be useful +10:54 < pinchartl> H3 + expansion +10:54 < pinchartl> V3M +10:54 < pinchartl> H3 + kingfisher +10:54 < pinchartl> and of course cameras +10:54 < pinchartl> I'll bring the kingfisher-based setup +10:55 < pinchartl> Kieran and Niklas, you're the only ones to have cameras, please bring them +10:55 < jmondi> easy for me: I have nothing +10:55 < pinchartl> we'll focus on the RDACM20 +10:55 < pinchartl> but it would be useful to have some RDACM21 just in case +10:55 < pinchartl> 8 should be enough, there's no need to have 16 +10:55 < kbingham> I'll bring hte RDACM21's too ... they won't take up much room. +10:56 < pinchartl> the V3M is with Kieran if I'm not mistaken, Niklas you don't have one, right ? +10:56 < kbingham> I have V3M yes. +10:57 < kbingham> https://osdr.renesas.com/projects/linux-kernel-development/wiki/Hardware says neg has one too! +10:57 < pinchartl> I'm not sure we will need the V3M though +10:58 < neg> Yes I have a V3M +10:58 < pinchartl> Kieran, you've worked on GMSL for V3M, would you focus on H3 + expansion or on V3M ? +10:58 < pinchartl> maybe Niklas could bring the V3M and Kieran the H3 + expansion ? +10:59 < neg> And I will bring all 16 cameras in case there should be some trading, maybe it would be useful to return some to pinchartl as he now has a kingfisher? +10:59 < pinchartl> neg: but then it would be useful if you could test Kieran's GMSL V3M patches beforehand, to make sure your hardware is functional +10:59 < pinchartl> neg: good point +10:59 < neg> pinchartl: I have tested my V3M and I can capture from it +10:59 < pinchartl> neg: perfect :) +11:00 < pinchartl> so that would be one H3 + expansion (Kieran), one V3M (Niklas) and one Kingfisher (Laurent) +11:00 < pinchartl> I think that should be enough +11:01 < pinchartl> jmondi: would you be able to bring your scope ? +11:01 < jmondi> I could, yes +11:02 < pinchartl> I'll bring a multimeter, a second one would be useful if someone could bring one +11:02 < jmondi> I have no boards, after all :) +11:02 < pinchartl> jmondi: I'd advise packing the scope in carry-on luggage and the probes in checked luggage +11:02 < jmondi> pinchartl: why that? +11:02 < pinchartl> because the scope is fragile and the probes are pointy +11:03 < pinchartl> you might have trouble going through security with the probes +11:03 < jmondi> indeed +11:03 < jmondi> I hope I'll be able to carry the scope in my carry-on +11:03 < pinchartl> and I would be worried packing a scope in checked luggage, as there are risks of losing it (or getting it stolen) +11:04 < jmondi> yes, I was thinking the same +11:04 < jmondi> I should be able to bring it, no worries +11:05 < geertu> FWIW, I had no issues with my scope probes when going to San Sebastian +11:05 < jmondi> geertu: better safe than sorry +11:06 < pinchartl> I'll bring a multimeter, a second one would be useful if someone could bring one +11:06 < jmondi> or, better safe than inspected +11:06 < pinchartl> oops, sorry, already mentioned that :) +11:06 < pinchartl> who has a multimeter he can bring ? +11:06 < geertu> I did suffer from my racial profiling in Biarritz, I think. +11:06 < neg> kbingham: I can bring my logic probe, is it possible to prep the break-out camera with i2c probe points? Or do the camera still break if probes are attached? +11:06 < jmondi> pinchartl: I do have a very basic one +11:06 < kbingham> neg: I'll bring hte breakout yes. The points are still attached and glued. +11:06 < neg> kbingham: greate! +11:07 < jmondi> geertu: being belgian increases the chances of being randomly selected for inspections in France? +11:07 < pinchartl> neg: good idea, thanks +11:07 < geertu> When I had issues understanding their "French", they asked where I was from, and immediately stopped bothering me. +11:07 < pinchartl> jmondi: please bring the multimeter if you can, thanks +11:08 < pinchartl> please all bring cables (network, USB and display) and power supplies for all the boards you will bring +11:08 < geertu> So I guess their French was the local Spanish from just across the border +11:08 < pinchartl> we will need power strips. in the worst case we can buy them in Belgium, but if you have space in your luggage please think about bringing a power strip +11:09 < kbingham> And a network switch +11:09 < kbingham> I can bring one - but it will be powered by a UK plug - an EU plug version would be useful. +11:09 < pinchartl> I only have a small 4-ports switch. can someone bring a larger one ? we'll need 8 ports +11:10 < pinchartl> kbingham: agreed +11:11 < pinchartl> I'll try to bring the power strip I bought in San Sebastian :) +11:11 < jmondi> I have a shiny new 8 ports switch +11:11 < neg> I also only have small 4port switch, but can bring if there is a need +11:11 < pinchartl> jmondi: could you bring it ? +11:11 < jmondi> still to be unpacked +11:12 < jmondi> I will +11:12 < pinchartl> thank you +11:12 < pinchartl> anything else we need to bring ? +11:12 < jmondi> I would like to write this list down... wiki page? +11:13 < pinchartl> I'll include it in the meeting report but we can add it to the wiki, yes, that's a good idea +11:13 < jmondi> doing it right now +11:13 < pinchartl> thank you +11:14 < pinchartl> that's it for me for the GMSL code camp topic +11:15 < pinchartl> the last topic for today is the next meeting, which will be held on 2018-01-25 (back on a Thursday) at the usual time +11:15 < pinchartl> is there anything else than anyone wants to discuss ? +11:16 < pinchartl> regarding the GMSL code camp I still want to synchronize with all of you and make sure we won't be blocked by any missing dependency but we can do that later +11:16 < neg> Anything else then GMSL preparations that should be prepared for the face-to-face meeting? +11:16 < pinchartl> this afternoon if everybody is available +11:17 < pinchartl> neg: good point. I don't think there's any need to prepare anything (well, I'll prepare a planning proposal), but if there's any topic you'd like to discuss, please submit it by e-mail +11:17 < wsa_> I'd like to discuss the time slots on 2018-01-25 +11:17 < wsa_> but we can do that by mail +11:17 < jmondi> pinchartl: sorry, I didn't get it.. would you like to meet thsi afternoon? +11:18 < wsa_> if possible, I'd like if IO is not first; the later the better +11:18 < pinchartl> jmondi: yes, to discuss GMSL, if you're available +11:18 < pinchartl> wsa_: multimedia has a tendency to spread over the 30 minutes boundary so it's convenient if it's last, but I'm sure we can find a schedule that will suit everybody +11:19 < neg> this afternoon works for me, I will work as always until ~17:00 CET then a break until ~22:00 CET. But is avilable inbetween if scheduled time as I try to do something else then sit at my desk duing the break :-) +11:19 < pinchartl> any time from 14:00 to 17:00 CET is fine with me +11:19 < jmondi> any time before 7pm is fine with me +11:20 < morimoto> So, JaPERIese side will quick.

I know you usually have lunch late +11:23 < jmondi> no, it's fine +11:23 < pinchartl> ok +11:23 < jmondi> I can have lunch while talking with you :) +11:24 < pinchartl> it's settled then +11:24 < pinchartl> any other topic for today? +11:26 < neg> pinchartl: shall we try for the lager test after the GMSL meeting? +11:26 < pinchartl> neg: yes, or even at the same time :-) +11:26 < neg> pinchartl: sure :-) +11:26 < pinchartl> no other topic, I propose adjourning this meeting. does anyone second ? +11:27 < jmondi> yup!

Or a board with either 1 or 2 GiB populated? +09:46 < Marex> geertu: not ES revisions, that may not work if someone mixes and matches boards and CPUs +09:47 < morimoto> shimoda-san is talking with our boss now +09:47 < geertu> Marex: We already have that issue, as the H3 SiPs on Salvator-X and H3ULCB are different (different memory size + ???) +09:47 < Marex> geertu: isnt there some SMC call which can give you the DRAM configuration ? +09:47 < geertu> Marex: no idea +09:47 < Marex> geertu: that might be the thing to explore +09:47 < Marex> geertu: that way we can be always correct IFF the ATF is correct +09:48 < geertu> Marex: Yes, you want a shared U-Boot binary, while the ATF is still per-SoC +09:48 < Marex> geertu: I want one u-boot to rule them all ! +09:48 < Marex> geertu: one u-boot binary, with different DT attached to it on per-board basis, that'd be AWESOME +09:49 < Marex> geertu: but if we can avoid having per-memory-configuration DT for u-boot, that'd be AWESOME too +09:50 < Marex> geertu: ... before you mention applying DTOs to U-Boot DT, yes, I tried it, no, I don't want to go down that path here ;-) +09:51 < geertu> At one point, I considered SiP DT bindings and .dtsi +09:51 < geertu> "[PATCH 0/8] arm64: dts: renesas: Break out R-Car H3 and M3-W SiP" +09:51 < geertu> https://www.spinics.net/lists/devicetree/msg173820.html +09:51 < shimoda> geertu: sorry for delayed.

Wolfram reviewed a ton of patches all around, discussed some watchdog +09:05 < wsa_> isses, made preparations for OSS+AGLJ, got the IP core switcher series merged, and +09:05 < wsa_> worked on virt tasks, generic one and I2C specific one. +09:05 < wsa_> B) +09:05 < wsa_> Simon wants to look at the CLK changes needed for HS400 and will continue with +09:05 < wsa_> the virt task. Niklas wants to send out V2 of RAVB-MTU size patch and, if time +09:05 < wsa_> permits, look into his previous SDHI hack. Shimoda-san wants to work on USB3.0 +09:05 < wsa_> role swap, USBPHY GPIO support, M3-N USB enablement and the virt task. Ulricht +09:05 < wsa_> will send out patches to the solutions of the above SCIF tasks. Wolfram will +09:05 < wsa_> finish the IO virt task today and fully move to the virt+I2C task, continue +09:05 < wsa_> reviewing stuff, submit the talk proposal for AGL, keep at the watchdog issues, +09:05 < wsa_> and plans to talk with Kieran about reprogrammed I2C addresses. +09:05 < wsa_> C) +09:05 < wsa_> Geert noticed eMMC problems on resume. Simon needs a SDR104 card in the Porter +09:05 < wsa_> board of Magnus' farm. +09:05 < wsa_> Please check if I misunderstood something. And fire away questions if you have. +09:06 < wsa_> I have one +09:06 < wsa_> geertu: which branch showed the eMMC problem? linus or ren-drivers? +09:06 < geertu> wsa_: That was my dev branch, based on renesas-drivers. +09:07 < geertu> Haven't tried it on anything else. +09:07 < geertu> I recently started using the eMMC for native compilation of QEMU, as it's much faster than nfsroot +09:07 < wsa_> oh, and anothso, with HS400? +09:07 < geertu> Hence I don't know if it happened before. +09:07 < wsa_> with HS400? +09:08 < geertu> I guess you have experience with mounted SD cards and s2idle/s2ram? +09:08 < geertu> No HS400, AFAIK +09:08 < wsa_> Simon once reported suspend&resume problems with SDHI, too +09:08 < wsa_> don't recall the details anymore +09:09 < wsa_> there was never time to look into it :( +09:09 < wsa_> i'll boost priority on this one a bit +09:10 < wsa_> neg: what about the hack to increase the MTU size beyond 2k? Not tried or didn't work? +09:10 < geertu> I can do some more tests, after reporting +09:10 < wsa_> geertu: Thanks, much appreciated! +09:11 < wsa_> geertu: and doing native compiles, you would probably also like the HS400 patches :) +09:11 < horms> wsa_: those s2ram/sdhi problems were a long time ago +09:11 < neg> wsa_: it did not work out as I planed :-( Not sure if it can be done, not given up entierly on it, but won't presue it in the near future. Shimoda-san told me of this HW limitation at the beginning of the task but I tought I could break it :-) +09:11 < horms> I think they have been resolved though I don't recall how +09:12 < horms> On the porter/sdr104 front, there is a card present, but I think its in the wrong slot (not all slots support that speed) +09:13 < wsa_> neg: yeah, that's understandable. Well, maybe somewhen... +09:14 < wsa_> horms: that should be easily fixable ;) +09:14 < horms> yes, its not a large problem +09:14 < horms> nor an urgent one +09:14 < horms> my larger problem is the clk patch for HS400. I think you and I need to talk about that some time. +09:15 < wsa_> yes, we can do that +09:15 < horms> I suspect you have a different eMMC chip on hour H3 ES1.0 board +09:15 < wsa_> somewhen next week +09:15 < horms> sure, lets schedule a time (some time) +09:15 < wsa_> I can't check right now, but I recall something like this, yes +09:15 < horms> ok, i guess you need to go home first +09:15 < horms> let me know when the timing is good for you +09:16 < wsa_> monday should be good +09:16 < geertu> wsa_: How long before the eMMC will wear out? +09:17 < horms> ok, i should be around on monday. but if you want to schedule a time let me know +09:17 < horms> geertu: just before we confirm the bug fix +09:17 < wsa_> horms: let's try the ad-hoc method, I'd say +09:17 < horms> ok, sur +09:18 < horms> in general mornings are better for me, say from 9 to noon +09:18 < wsa_> geertu: so, tried to wear out a 64MB SD card once because I wanted to check if SDHI catches such errors well. +09:18 < horms> but mondays are pretty good in general +09:18 < wsa_> I wrote continously for days while hacking, no luck +09:19 < wsa_> but maybe that card was not MLC +09:20 < wsa_> so, do you guys have questions? +09:20 < wsa_> I am done, I think +09:21 < wsa_> JapaPERI is happy, too? +09:22 < shimoda> yes, but i cannot catch up the emmc issue though :) +09:23 < horms> shimoda: issue is that hs400 is working fine for me. but it involves patches that wsa_ has had trouble with before. next step if for wsa_ to verify the current patchset in his environment, then discuss +09:24 < horms> It seems likely his H3 1.0 and mine have different eMMC chips. but we should test before speculating more +09:25 < shimoda> horms: thanks! and geertu has other issue (doesn't work after resume) +09:27 < kbingham> wsa_: I'm happy to talk I2C addreses whenever you're free +09:27 < shimoda> about H3 1.0, i think it is very bad chip about clock thing +09:27 < kbingham> :) +09:27 < wsa_> kbingham: nice, we will see when. hopefully next week, but no promise yet +09:27 < kbingham> wsa_: Ack :) +09:28 < horms> shimoda: ok. so some boards have a chip that works badly with the clk fix? that would explain things +09:28 < horms> do you know which chip? +09:29 < wsa_> or maybe it is because some clks are running only at 50%? +09:29 < wsa_> we need to check, but keep in mind that ES1.0 is special regarding to clocks +09:30 < geertu> Yes, it has completely different handling for SD clocks, IIRC +09:31 < geertu> You may need to measure the actual clock signals... +09:31 < wsa_> heh +09:31 < horms> I suggest we take this offline and move onto Core +09:31 < wsa_> we will come back to this once I am back home +09:31 < wsa_> agreed +09:32 < wsa_> thanks for the meeting! +09:32 < wsa_> geertu: the stage is yours diff --git a/wiki/Chat_log/20180215-mm-chatlog b/wiki/Chat_log/20180215-mm-chatlog new file mode 100644 index 0000000..630960d --- /dev/null +++ b/wiki/Chat_log/20180215-mm-chatlog @@ -0,0 +1,334 @@ +Multimedia-chat-meeting-2018-02-15 + +10:01 < pinchartl> Topic 1.

+10:36 < morimoto> I have one +10:37 < morimoto> Before BSP team asked that they want to use DU / VSPD separately +10:37 < morimoto> Do you have such support plan ? +10:37 < pinchartl> on Gen3 ? +10:37 < morimoto> Yes +10:38 < pinchartl> how do they want to do that ? the DU requires VSPD for proper operation +10:38 < pinchartl> or does it mean they want to use the VSPD standalone when the corresponding DU channel is not needed ? +10:38 < morimoto> "separately" means, DU can be separate. They want to use 1 for Linux 1 for VM +10:38 < morimoto> for example +10:38 < pinchartl> ah ok +10:39 < pinchartl> I thought you meant using the DU and the VSPD separately from each other +10:39 < pinchartl> so they want to make some of the DU pipelines available to guests ? +10:39 < morimoto> Ah, sorry for my English +10:39 < pinchartl> no worries :-) +10:39 < morimoto> Yes +10:39 < morimoto> I think we talked it before ? +10:40 < morimoto> It is still our Todo list (In Renesas) +10:40 < morimoto> BSP team already have local patch, so, not a big deal +10:40 < pinchartl> I've worked on display virtualization in Q1/1, I'll send the report today +10:40 < pinchartl> the approach I've tested was paravirtualization, not pass-through +10:41 < pinchartl> we'll have to decide what is best +10:41 < pinchartl> there are two issues +10:41 < pinchartl> one is that on some SoCs (namely H3 ES2.0) a single VSPD instance handles two DU pipelines +10:41 < pinchartl> so those two pipelines can't be used in separate VMs +10:42 < pinchartl> LVDS for one guest and VGA for another guest won't be possible on H3 ES2.0 with pass-through +10:42 < pinchartl> but LVDS + VGA for one guest and HDMI for another guest should work +10:42 < morimoto> Yeah, some HW issue exist. +10:43 < pinchartl> the second issue is that the DU groups channels by two +10:43 < pinchartl> with shared resources +10:43 < pinchartl> so we can assign a group of two channels to one guest and another group to another guest +10:43 < pinchartl> but not split a group +10:44 < pinchartl> and unfortunately, on H3 ES2.0, the VSPD instance shared by two channels is split between two groups +10:44 < pinchartl> that's why I think a paravirtualized approach might be better +10:44 < pinchartl> but lots of work is still needed to prototype all that and see what we can do +10:44 < pinchartl> it's really long-term work +10:45 < pinchartl> especially if we want to make it upstream +10:45 < pinchartl> given the time we currently allocate to virtualization work, I wouldn't expect any upstream solution before the end of the year +10:46 < morimoto> OK, we knew some HW limitation exist, and we think we need to consider this kind of limition somehow +10:46 < pinchartl> yes +10:46 < morimoto> Actually, HW team didn't care about virtualization when they created chip +10:46 < pinchartl> that's interesting to know +10:47 < pinchartl> and now someone cares about virtualization ? :-) +10:47 < morimoto> That is the reason why it has such design +10:47 < morimoto> SW team start to consider virtualization, HW team didn't care +10:48 < pinchartl> does the software team have use cases that they can share for virtualization ? +10:48 < morimoto> The reason why it has not enough channel/IP/connection is HW team want to reduce cost +10:48 < pinchartl> I hope someone will tell the hardware team it wasn't the best idea +10:48 < morimoto> Just cost issue, no plan for virtualization +10:49 < pinchartl> there are a few things I consider as design mistakes in the DU +10:49 < morimoto> Yes, Now they noticed (I hope) +10:49 < pinchartl> I would really like to see them fixed at some point +10:49 < morimoto> I guess Gen4 timing +10:50 < morimoto> I think Renesas SW team will have discussion time with HW team then +10:50 < pinchartl> could the HW team listen to our feedback ? +10:50 < morimoto> Gen3 was better than Gen2. becaming better, but not yet perfect +10:51 < morimoto> That is the request from Renesas CEO +10:51 < morimoto> But, HW team have their reason. Thus, not 100% +10:52 < pinchartl> I wonder whether it could be useful to meet face to face before OSSJ to discuss Gen4 DU with the hardware team +10:53 < morimoto> Uhm, I don't know we can do it. +10:53 < morimoto> But let's try to ask +10:53 < pinchartl> thank you :-) +10:53 < morimoto> Thank you. it is all from me +10:54 < pinchartl> this leads us to Topic 3.

I do not even eat it, it would be a waste +11:08 < jmondi> personally, the planning poker card has been really helpful to reason on task commitment +11:09 < neg> I also liked the early start in the days and that take-out food was had some nights to prolong the hacking sessions +11:11 < neg> Things to improve I think is that ad-hoc decisions taken during the week to prior to the MM meeting where not documented +11:11 -!- pinchartl_ [~unknown@81-175-216-236.bb.dnainternet.fi] has joined #periperi +11:12 < jmondi> neg: didn't get this +11:12 < pinchartl_> my hosted server stopped replying :-/ +11:12 < neg> jmondi: thing I think we should improve or take-out food? +11:12 < pinchartl_> the last thing I saw was +11:12 < pinchartl_> 11:08 < jmondi> personally, the planning poker card has been really helpful to reason on task commitment +11:12 < pinchartl_> what have I missed ? +11:13 < jmondi> pinchartl_: need logs? +11:13 < pinchartl_> please +11:13 < jmondi> pinchartl_: https://paste.debian.net/hidden/0e0035b0/ +11:14 < jmondi> you didn't miss much though +11:14 < pinchartl_> thank you +11:15 < pinchartl_> neg: what did you mean ? +11:15 < pinchartl_> by "Things to improve I think is that ad-hoc decisions taken +11:15 < pinchartl_> during the week to prior to the MM meeting where not documented" +11:16 < neg> For example we talked about the GMSL branch names ad-hoc and that was not documented and now we are confused :-) +11:16 < pinchartl_> (I think my server is being DOSed) +11:16 < pinchartl_> yes, I agree +11:17 < pinchartl_> maybe we should create a wiki page for the next code camp +11:17 < pinchartl_> and take notes whenever needed in a collaborative way +11:17 < pinchartl_> or an etherpad +11:18 < jmondi> neg: other non documented points you are thinking about? +11:18 < jmondi> because I cannot even remember the naming scheme thing :p +11:18 < kbingham> I think that may have just been an informal ish discussion between me and neg :D +11:18 < neg> Also we did not execute the plan to do a team event which was OK but I think it would have been good for the team. *real issue: brought my swimsuite and we did not go diving :-)* +11:19 < pinchartl_> :-) +11:19 < pinchartl_> I agree too +11:19 < pinchartl_> I think we did better than in San Sebastian +11:19 < pinchartl_> but still not good enough +11:19 < pinchartl_> from a social events point of view +11:20 < neg> jmondi: none that come to mind regarding un-documented stuff, but I was not part of all discussions nor do I remember all of them I took part in +11:20 < pinchartl_> several ideas for a social event were discussed before the meeting but we haven't officially agreed on anything, so nothing happened +11:21 < jmondi> we would had been short on time probably for social events... +11:21 < pinchartl_> next time I think we need to decide beforehand on what we want to do +11:21 < pinchartl_> yes, that too, but we will always be short of time anyway :-) +11:21 < neg> Yes, I too think if we are to make an event happen we should pre-allocate time for it +11:22 < jmondi> my understanding is that we're not meeting in Q2/Q3, right? +11:22 < jmondi> at least, not with Renesas sponsorship... +11:22 < pinchartl_> we should definitely meet +11:23 < pinchartl_> I assume there will be a meeting similar to San Sebastian around September +11:23 < pinchartl_> hopefully in Italy :-) +11:23 < pinchartl_> and I think another code camp at some point over the summer would be useful +11:24 < jmondi> pinchartl_: yeah, I meant before september, sorry.. +11:27 < pinchartl_> that's it for me +11:27 < pinchartl_> any other topic to discuss ? +11:27 < jmondi> I would like to ask you guys if I'm the only one that had to spend a day to cross-compile v4l-utils +11:28 < kbingham> jmondi: Normally I can just type 'make v4l2-utils' on my build - but the build does seem to have broken at the moment ... +11:29 < jmondi> it has a -ton- of dependencies, doesn't live well will musl or ulibc.. I remember buildroot shipped versions worked fine, with last version is a bit of pain... is it me? +11:29 < jmondi> kbingham: that's buildroot? +11:29 < neg> jmondi: I build it as a Arch packege on target and then install that in my NFS root for each board, if it helps :-) +11:29 < kbingham> So I'd say this is the life with cross compiling +11:29 < pinchartl_> I cross-compile it outside of buildroot without any issue +11:29 < kbingham> jmondi: (No that's my own custom outside-of-buildroot) +11:29 < kbingham> All it does is git clone the latest v4l2-utils, and attempt to configure and build inside my working environment. +11:30 < jmondi> neg: cross compile as arch package? that's nice +11:31 < jmondi> ok, I assume it is me then, I had to add a ton of packages to buildroot produced compiler sysroot to satisfy dependencies... +11:31 < neg> jmondi: not cross compile, Arch build system don't support that so I have to build the package on target (or in arm/arm64 VM but I don't have that) +11:31 < neg> jmondi: also "sed -i '/#define HAVE_QTGL 1/d' config.h" helps :-) +11:32 < jmondi> neg: oh, you're building on target! that's nasty :) +11:33 * kbingham adds a cross-docker environment which uses qemu-system-arm to provide a 'lightweight ARM64 VM' on host. +11:33 < kbingham> to his wish list +11:33 < jmondi> ok, that's all from me, just wanted to make sure I was not doing something super stupid... +11:34 < kbingham> Ok - back to report writing it is then :) +11:34 < jmondi> (/me wonders how pinchartl_ can build with the single line ./configure string he shared) +11:39 < pinchartl_> are we done for today ? +11:40 < neg> I have nothing more +11:42 < pinchartl_> then we're done +11:42 < pinchartl_> thank you for attending diff --git a/wiki/Chat_log/20180301-core-chatlog b/wiki/Chat_log/20180301-core-chatlog new file mode 100644 index 0000000..b351f51 --- /dev/null +++ b/wiki/Chat_log/20180301-core-chatlog @@ -0,0 +1,110 @@ +Core-chat-meeting-2018-03-01 + +09:49 < geertu> Welcome to today's Core Group Chat! +09:50 < geertu> First I'd like to welcome Vaishali +09:50 < geertu> Agenda: +09:50 < geertu> 1. Status Updates +09:50 < geertu> 2. Discussion Topics +09:50 < geertu> Topic 1. Status updates +09:51 < geertu> A) What have we done since last time: +09:51 < geertu> Jacopo continued upstreaming basic R-Car M3-N support. +09:51 < geertu> Niklas fixed the CLKOUT duplicate pin on R-Car H3 ES2.0. +09:51 < geertu> Shimoda-san discovered a new IPMMU issue on R-Car H3 ES3.0, and submmitted +09:51 < geertu> USB-related PFC patches for R-Car M3-N. +09:51 < geertu> Simon posted R-Car M3-N initial infrastructure patches. +09:51 < geertu> Ulrich up-ported PFC work for R-Car H3/M3-W from the BSP (TMU/HDMI/fixes). +09:51 < geertu> Geert did some R-Car M3-N work (initial Salvator-XS DTS, s2ram), and more +09:51 < geertu> watchdogi investigation (blacklisted early R-Car Gen2 SoCs, Gen2 vs. Gen3 +09:51 < geertu> comparison). +09:51 < geertu> Marek is excused, and enjoying(?) Embedded World +09:52 < geertu> B) What we plan to do till next time: +09:52 < geertu> Shimoda-san will submit PWM PFC and USB DTS patches for R-Car M3-N, and +09:52 < geertu> discuss with Magnus a plan to improve the IPMMU driver. +09:52 < geertu> Simon will probably do more DTS cleanup work (soc node and sorting). +09:52 < geertu> Geert will post V2 of in-kernel BD9571MWV DDR backup mode, and revisit vfio +09:52 < geertu> and qemu patches. +09:52 < geertu> C) Problems we have currently: +09:52 < geertu> Geert wonders if s2ram (PSCI suspend) works on ULCB, and Shimoda-san +09:52 < geertu> confirmed it. +09:53 < geertu> Anything I missed? +09:55 < geertu> Topic 2. Discussion Topics +09:55 < geertu> 1. SW feedback to HW team for R-Car Gen4. +09:55 < geertu> Personally, I have the following: +09:55 < geertu> - Virtualization: +09:55 < geertu> - All device instances should be resettable independently +09:55 < geertu> (e.g. PWM and DU share resets). +09:55 < geertu> - All device instances should be mappable independently +09:55 < geertu> (e.g. GPIO5/6/7 share (4 KiB) pages) +09:56 < geertu> Any other feedback? +09:56 < geertu> (IOMMU? ;-) +09:56 < neg> geertu: I have MM related feedback, do we split this per group or handle the topic for all groups now? +09:57 < geertu> neg: I think it makes sense to do it per-group, that's why I didn't mention your feedback +09:58 < neg> geertu: :-) +10:01 < geertu> OK, core is further perfect ;-) +10:01 < geertu> 2. RZ/N1D upstreaming. +10:01 < jmondi> no feedbacks from me (apart general reamarks on PFC, but I don't think they will listen :) +10:01 < geertu> So Renesas submitted two large patches to add support for RZ/N1D on the RZ/N1D-DB Board +10:02 < geertu> From a quick glance, there are several arres for improvement: +10:02 < geertu> - Too large patches +10:02 < geertu> - Board code +10:02 < geertu> - Macros in DTS +10:03 < geertu> So far I didn't reply in public, as I feel this is more appropriate for the official mach-shmobile maintainers +10:03 < jmondi> can I ask some questions on those patches, for informative purpose? +10:03 < geertu> jmondi: Sure +10:03 < jmondi> why they had to use board code? I see r7s72100 does the same... +10:04 < jmondi> I guess it's beacuse RZ is njot integrated in cpg-mssr, right? +10:04 < jmondi> and even in that case, why do not use something like drivers/clk/rz/ and drivers/soc/rz/ ... +10:06 < geertu> Probably we can get rid of arch/arm/mach-shmobile/setup-r7s72100.c +10:06 < geertu> It predates true DT support +10:06 < geertu> I guess they just took the quick and dirty approach +10:07 < geertu> horms: dammsan: Any comments from the mach-shmobile maintainers? +10:08 < horms> Well, my assumption is that the upstream policy is no more board files +10:08 < horms> So from my point of view the question is: how can support be added for RZ/N1D without a board file +10:09 < horms> There is also a similar, but arguably smaller, issue of a defconfig for the platform +10:09 < geertu> The board file contains sysctrl initialization (should be syscon node in DT instead), and a restart handler (should be a drivers/power/reset/ driver) +10:10 * jmondi thorws himself into the fire: I would like to remove board code from RZ/A... do you think there is any value there and it can be reused for RZ/N? +10:10 < dammsan> i agree =) +10:10 < geertu> There's not much R-{Car,Mobile} DNA shared +10:11 < geertu> jmondi: I encourage that task. But the board code for RZ/N1D is completely different from the one for RZ/A1. +10:12 < jmondi> I admit I haven't looked into RZ/N1D HW at all yet +10:14 < geertu> Looks like the DTB isn't even built... +10:14 < horms> Ok, so I think we should push back +10:14 < horms> I can do so. But I'm happy for someone else to do so. +10:14 < geertu> horms: Will you reply? +10:14 < geertu> IC +10:14 < horms> But we can't try to push a board file unless we have no other practical option +10:14 < geertu> I can reply with some technical feedback +10:14 < horms> Sure, will do +10:15 < dammsan> thanks guys +10:15 < horms> Thanks for bringing this up, I was also not sure how to proceed +10:15 < shimoda> about RZ/N, we don't need any document for now? +10:16 < geertu> shimoda: You are trying to get documentation, IIRC?

Kaneko-san prototyped support for D3 +09:08 < wsa_> thermal. Geert fixed alias usage for serial drivers and enabled IIC on M3N. +09:08 < wsa_> Niklas got his resizable MTU patch merged (what about David's remark?). +09:08 < wsa_> Shimoda-san added USB support for M3N. Wolfram finished his generic +09:08 < wsa_> virtualization task and is now evaluating I2C passthrough, reviewed HS400 +09:08 < wsa_> patches and assorted SDHI clock dividing, and worked on watchdog requests. +09:08 < wsa_> Uli got his SCIF patches merged. +09:08 < wsa_> B) +09:08 < wsa_> Simon wants to test HS400 on M3M and continue with his QEMU task. Kaneko-san +09:08 < wsa_> wants to send out support for D3 thermal. Geert wants to remove hard dependency +09:08 < wsa_> of serial aliases (needed for I2C as well?). If time allows, Niklas wants to +09:08 < wsa_> recheck the SDHI issue workaround patch he once created. Shimoda-san has +09:08 < wsa_> multiple USB issues to work on (role swap for SS, GPIO support for USB PHY, +09:08 < wsa_> resume issue) and also learns about USB virtualization. Wolfram wants to finish +09:08 < wsa_> his virtualization task, give HW team feedback about I2C IP core, pick up more +09:08 < wsa_> SDHI work, write a talk proposal for AGL, and still wants to talk with Kieran +09:08 < wsa_> about I2C addresses. +09:08 < wsa_> C) +09:08 < wsa_> Simon checked that SDR104 on Porter still fails (test Niklas patch maybe?). +09:08 < wsa_> Wolfram so far depends on gmane NNTP for reporting, but it has become +09:08 < wsa_> unreliable in the last days. +09:08 < wsa_> so, one question to neg +09:08 < wsa_> neg: can something be done about David's comment about the MTU patch? +09:09 < wsa_> he said most users would want to have interfaces enabled when they resize MTU? +09:09 < wsa_> and a question to geertu +09:10 < neg> wsa_: I'm sure it can be done, but if we choose to do so I also think we should apply a simlar work to sh_eth +09:10 < wsa_> geertu: I don't think we need to remove hard dependencies on I2C busses, because they match the schematics. Am I correct? +09:10 < wsa_> neg: for sure. I just wondered if it can be done at all and if it was feasible to do so +09:11 < geertu> wsa_: The issue is not related to matching buses with schematics. +09:11 < wsa_> neg: I don't know the HW in enough detail to unterstand if it can be done at all with reasonable effort +09:11 < geertu> The sh-sci driver has a hard dependency on th presence of the serialN aliases. Without them, the driver won't probe. +09:12 < wsa_> geertu: Ah! +09:12 < geertu> This is mostly a relic from the serial core working with a fixed array of ports. +09:12 < neg> wsa_: Sure it's feasible but I think it will take some work as we would have to resize the rings while the nic is up. I have no plan to address this at this time, but if you think it's a good idea I can look at it as part of base +09:12 < geertu> It makes DT overlays more difficult (need to update /aliases) +09:12 < wsa_> geertu: i see. that definately should be removed. +09:12 < neg> wsa_: I think in it self it would be a usefull change for both our network drivers +09:13 < geertu> Note that on SPI the aliases are already optional, as the SPI subsystem handles dynamic bus numbers. +09:13 < geertu> I think I2C is similar to SPI w.r.t. this +09:13 < wsa_> geertu: yes +09:14 < wsa_> neg: well, if David says "most users would want this" and you also say it would be useful, I think we should target that +09:14 < geertu> wsa_: (checked) yes, see i2c_add_adapter() +09:14 < geertu> I think I can do something similar in sh-sci. I won't touch core serial, though ;-) +09:15 < wsa_> geertu: dragons live there +09:15 < wsa_> neg: I will add a todo item for it +09:15 < wsa_> neg: and you want to do it as part of a base task? +09:16 < neg> wsa_: I would be fine to do that in base but are open to other arangements +09:17 < wsa_> okay +09:17 < wsa_> we will see about that when the next round of add. tasks is due +09:18 < wsa_> if you happen to have free base time (yeah, right) until then, please have a go +09:18 < wsa_> so, simon is not here, we will handle my remark then by mail +09:19 < wsa_> status updates done, if there are no remarks from your side? +09:19 < wsa_> Then +09:20 < wsa_> Vaishali, nice to have you here.

But I did attend Julia's session, so that must be how I remembered. +09:32 < wsa_> okay, so for the remaining issues +09:32 < vthakkar> uli__: Magnus contacted me when Julia presented my work at Dublin one. Then for some reason, I had to take up a job at Oracle and then I met Magnus at 2-3 other conferences in last 2 years and we talked about the work your groups are doing. +09:33 < wsa_> morimoto: shimoda: what is your take on maybe not enabling eMMC HS400 mode on H3 ES1.0? +09:33 < wsa_> as far as I can see, we have no "recommended HW setting" for CPG for ES1.0 +09:34 < wsa_> and the one I tried on my own didn't work for writing data +09:34 < shimoda> wsa_: I don't remember about eMMC HS400 mode on H3 ES1.0 +09:34 < wsa_> or we could ask the HW guys if there is some recommended HW setting for ES1.0 maybe? +09:34 < shimoda> but, H3 ES1.0 is not good, especially clock thing +09:36 < shimoda> wsa_: hmm, I guess hw guys said you should not use ES1.0, but I'll ask anyway :) +09:36 < wsa_> shimoda: thank you. I agree that makes most sense, if they say "don't do it", then we won't do it +09:37 < wsa_> it = HS400 +09:37 < shimoda> wsa_: i got it +09:37 < wsa_> dammsan: are you here? +09:37 < wsa_> Marex: and you? +09:38 < dammsan> yep im here +09:38 < geertu> wsa_: Marex is excused (@EmbeddedWorld) +09:39 < wsa_> I see +09:39 < wsa_> dammsan: did you read the mail from Shimoda-san about listing the revisions in the SDHI driver? +09:41 < dammsan> yeah, I discussed this with him in the office today, and i only care about disabling disallowed combos from use, ie early ES versions. +09:41 < dammsan> one way to solve this could be a black list of those ES versions +09:41 < dammsan> but i have no strong feeling really +09:42 < wsa_> like blacklisting HS400 on ES1.0? ;) +09:42 < wsa_> I see +09:42 < wsa_> thanks for the heads up! +09:43 < dammsan> s/on ES1.0//g =) +09:43 < dammsan> thanks +09:43 < wsa_> okay, this was it from my side +09:43 < kbingham> wsa_: What topics would you like to discuss regarding I2C addresses, and when would you like to do so - I'm assuming it's related to us talking when we were in Brussels - but my memory has now faded.

I'll read later when next meeting is scheduled and I have no particular feedbacks for Gen4 +11:07 < jmondi> sorry about that +11:07 < pinchartl> jmondi: no worries +11:08 < pinchartl> while waiting for Geert to wake up, let's address +11:08 < pinchartl> Topic 4. SW Feedback to HW team for R-Car Gen4 +11:08 < pinchartl> * Niklas +11:08 < pinchartl> I find the VIN register VNCSI_IFMD_CSI_CHSEL to problematic and it have +11:08 < pinchartl> created a lot of extra work in driver development. The VIN instances are +11:08 < pinchartl> independent of each other and fits rather well with the Linux driver +11:08 < pinchartl> model in regard to PM and clocks etc. +11:08 < pinchartl> Since the VNCSI_IFMD_CSI_CHSEL are only present on VIN0 and VIN4 but +11:08 < pinchartl> controls input settings for VIN{1,2,3,5,6,7} this creates a dependency +11:08 < pinchartl> between the different VIN driver instances. This is annoying and I'm not +11:08 < pinchartl> sure if this really simplifies the hardware (I'm no hardware engineer)? +11:08 < pinchartl> As the register selects different inputs for different VINs based on a +11:08 < pinchartl> single integer value in the CHSEL register each VIN likely still have +11:08 < pinchartl> its own separate input multiplexing logic? +11:08 < pinchartl> I base this assumption on the presence of the VNMC_DPINE register which +11:08 < pinchartl> is yet another multiplexing selection bit which is present only in VIN4 +11:08 < pinchartl> and VIN5. This bit controls if the VIN input come from CSI-2 receiver or +11:08 < pinchartl> form the digital parallel input and this register is local to the VIN +11:08 < pinchartl> for which the selection is valid. +11:09 < pinchartl> neg: how would you like to see this implemented in Gen4 ? +11:10 < neg> I'm no HW engineer so there might be constraints I'm not aware of but in my mind makig the VNCSI_IFMD_CSI_CHSEL register local to each VIN and independent of each other would be nice if it where possible +11:12 < morimoto> it is almost same as geert's comment ? +11:12 < morimoto> - All device instances should be mappable independently +11:13 < pinchartl> if that can't be done, would moving it to a syscon help ? +11:14 < pinchartl> morimoto: I don't think so. the problem here is that a register field located in one VIN influences all VINs +11:14 < pinchartl> the VINs are still mappable independently +11:14 < neg> I'm not sure how a syscon would look like so I can't awensere that +11:15 < pinchartl> the register would be in a separate register space +11:15 < pinchartl> that would have its own DT node +11:15 < pinchartl> with a phandle pointing to it in all DT nodes +11:15 < pinchartl> s/DT nodes/VIN nodes/ +11:16 < neg> Yes I think that would help as a separate DT node and a separate driver would make things easier +11:18 < pinchartl> another issue from me +11:18 < pinchartl> * Laurent +11:18 < pinchartl> Resource sharing in DU and VSP is painful to handle in software. +11:18 < pinchartl> In Gen2 SoCs the DU shared a set of 8 planes per group of two DU channels. This was configured through registers that required both DU channels to be disabled to change the plane assignment. Moving a plane from one DU channel to another caused flicker on the screen as the two channels had to be disabled, even if the plane was disabled to start with (disabled planes were still assigned to one DU channel +11:18 < pinchartl> ). +11:18 < pinchartl> In Gen3 SoCs the problem disappeared as DU channels do not interface to memory directly anymore but go through VSP-D for that purpose. However, on H3 ES2.0, and on M3-N, the VSP-DL instance serves two DU channels (DU0 and DU3), creating a similar issue. The VSP-DL has 5 inputs and two blending units, BRU and BRS. The BRU can blend up to 5 inputs and the BRS up too 2 inputs. The BRU and BRS thus have to +11:18 < pinchartl> be assigned to the DU channels dynamically at runtime based on the number of inputs used by each channel. As the two DU channels run asynchronously, this requires stopping display on one channel to release the blending unit in use, reconfigure the other channel to use that blending unit, and finally restarting the first channel. This creates flicker on the screen. +11:20 < pinchartl> any comment ? +11:20 < pinchartl> Additionally, on both Gen2 and Gen3 resources shared by two channels in a group are controlled through registers in the first channel of the group. This prevents assigning DU channels from the same group to different guests in a virtualized environment.

This is annoying from a driver point of view, and it would be easier if each VIN had a CHSEL register that controlled its own input routing. +11:28 < neg> pinchartl: thank you +11:29 < pinchartl> ok, that's it for today +11:30 < pinchartl> any last comment ? +11:30 < pinchartl> still no word from Geert for the next meeting +11:30 < pinchartl> I'll propose having it in 3 weeks +11:31 < pinchartl> no more comment, meeting adjourned +11:31 < pinchartl> thank you all for attending diff --git a/wiki/Chat_log/20180322-core-chatlog b/wiki/Chat_log/20180322-core-chatlog new file mode 100644 index 0000000..38af15d --- /dev/null +++ b/wiki/Chat_log/20180322-core-chatlog @@ -0,0 +1,127 @@ +Core-chat-meeting-2018-03-22 + +09:40 < geertu> Welcome to today's Core Group Meeting! +09:41 < geertu> Laurent and Marek are excused +09:41 < geertu> Everybody else seems to be here +09:41 < geertu> Agenda: +09:41 < geertu> 1.

Status updates +09:42 < geertu> A) What have we done since last time: +09:42 < geertu> Marek added M3N support to mainline u-boot, revisited PCIe upports, and +09:42 < geertu> presented 4 talks about U-Boot in the US. +09:42 < geertu> Shimoda-san submitted M3-N usb related DTS patches, discussed about 4/8 +09:42 < geertu> GiB support for R-Car H3 ES3.0, and prepared IPMMU workarounds for R-Car +09:42 < geertu> H3 ES3.0. +09:42 < geertu> Ulrich sent fix-ups for VIN4 pin definitions. +09:42 < geertu> Geert sent the first clk and pfc pull request for v4.17, sanitized +09:42 < geertu> EtherAVB pin groups, sent V2 of in-kernel BD9571MWV DDR backup mode, and +09:42 < geertu> annotated upport items. +09:42 < geertu> (so I have received Simon's and Uli's emails in the mean time. Anything else I missed/still in email flight?) +09:43 < wsa_> except for discussion, no new updates arrived on my side +09:43 < jmondi> geertu: no updates for Core +09:43 < geertu> B) What we plan to do till next time: +09:43 < geertu> Shimoda-san will submit PWM PFC patches for R-Car M3-N, and +09:43 < geertu> discuss with Magnus a plan to improve the IPMMU driver, and will try to +09:43 < geertu> port initial code for R-Car E3 Ebisu. +09:43 < geertu> Simon will probably do more DTS cleanup work (soc node and sorting). +09:43 < geertu> Geert will send the second clk and pfc pull request for v4.17, and +09:43 < geertu> revisit vfio and qemu patches. +09:43 < geertu> jmondi: thx +09:44 < geertu> C) Problems we have currently: +09:44 < geertu> None (hmm) +09:45 < geertu> dammsan is playing with old boards? ;-) +09:46 < geertu> Topic 2.

We want to fix an issue in the WDT driver but can't sell it to the maintainers as is. We could sell it if we implement WDT handover from the bootloader :/ +09:56 < wsa_> However, that might be a customer use case, too, so it is not that bad... +09:57 < Marex> wsa_: wdt handover ? how would that work ? +09:57 < Marex> wsa_: ha +09:57 < Marex> wsa_: U-Boot will just leave the WDT on and the kernel/userspace should continue poking it, to prevent reset +09:58 < wsa_> Marex: I haven't looked into the details, but probably the driver needs to check if the WDT is already running and tell the Linux WDT core +09:58 < shimoda> horms: geertu: since we have no nice way for memory map configuration automaticaly, may I reply to BSP team about this? This means BSP team will create several DTS files :) +09:58 < geertu> Marex: +09:58 < horms> shimoda: i think that is the best option at this time +09:59 < shimoda> horms: i got it. thanks! +09:59 < geertu> Marex: If U-Boot could check if all memory banks exist, it could do probe of memory size +09:59 < dammsan> exactly +09:59 < wsa_> Marex: but however it works, a way to start the WDT in U-Boot will be needed ;) +09:59 < geertu> Looks like md doesn't handle > 32-bit addresses? +09:59 < geertu> Or is it not mapped? +09:59 < dammsan> checking the ddr controller settings must be possible? +09:59 < geertu> md = U-Boot md command +10:00 < shimoda> horms: i have one more question. when bsp team creates 2 types of DTS, one of dts file can include another one? +10:00 < geertu> dammsan: ATF is responsible for programming the DDR ctrlr, right? +10:00 < dammsan> most likely +10:01 < dammsan> but determining the setting during runtime from u-boot might be possible? +10:01 < dammsan> other platforms must have the same issue +10:01 < geertu> shimoda: Yes, the sample 8-gb dts you had, including the 4-gb .dts and overriding it, looks fine to me (if we go the route of multiple dts) +10:02 < geertu> But I'd like to avoid the proliferation of DTSes +10:02 < dammsan> geertu: me too +10:02 < shimoda> geertu: I got it, thanks! I will forward this information to BSP team +10:02 < geertu> So if U-Boot can autodetect, that would be great +10:03 < dammsan> indeed +10:04 < geertu> We can e.g. compare DDR register between M3/Salvator-X and M3ULCB (4 GiB vs. 2 GiB) +10:05 < horms> shimoda: yes, i think there is an example of that for the RZ/G1 DT +10:07 < dammsan> geertu: or do a simple write-read test for mirroring +10:07 < shimoda> horms: thanks for the RZ/G1 info. I'll look that +10:08 < geertu> dammsan: If it shows up as a mirror copy of the existing RAM. It may go buserr, too. +10:08 < dammsan> but which areas that are mapped can probably be determined by DDR controller settings or similar +10:08 < geertu> yes +10:09 < dammsan> to see if it is safe to access them or not +10:09 < geertu> If U-Boot can access the registers (you never know with ATF) +10:09 < dammsan> true +10:10 < Marex> geertu: can't you do SVC call into the ATF to determine the memory size ? +10:10 < Marex> geertu: but then again, Id like to have one set of blobs per SoC (or even per family) +10:11 < dammsan> that would make sense +10:11 < geertu> On your M3ULCB, the non-existing memory at 80000000 reads back zeroes +10:11 < Marex> geertu: so being able to detect the DRAM size would be very welcome +10:11 < geertu> Marex: AFAIK there's no memory size API in the ATF +10:11 < geertu> Writing to 80000000 works (= does not crash), still reads back zeroes afterwards +10:11 < Marex> (I want to complain about ATF being sub-optimal, but I guess everyone knows my opinion on it) +10:11 < dammsan> worst case we can use spectre/meltdown to determine memory size without bothering ATF =) +10:12 < geertu> On M3/Salvator-X, I can read/write at 80000000 fine +10:12 * pinchartl is back +10:12 < shimoda> dammsan: sorry for the delay, about write-read test for mirroring is not good because the hw might caure deadlock. +10:13 < geertu> If H3 ES3 and E3 behave the same, we can probe that way +10:13 < geertu> shimoda: Yeah, that was my worry too, but it seems to work on M3-W SiP ;-) +10:13 < dammsan> shimoda: it would have to be probed in a certain safe order for it to be useful +10:14 < dammsan> shimoda: do you think it is impossible? =) +10:15 < shimoda> dammsan: BSP team asked hw guys about the this topic, and then hw guys rejected this approauch because this way is possible to cause deadlock +10:15 < geertu> Hmm, e6790000 reads back as zeroes +10:15 < geertu> so DBSC4 is protected? +10:17 < shimoda> geertu: I guess DBSC4 reg area is in secure world +10:18 < geertu> shimoda: So we cannot read the DBSC4 regs, but can cause deadlock by reading non-existent memory? ;-) +10:18 < dammsan> shimoda: thanks for explaining =) +10:19 < shimoda> geertu: yes :) +10:19 < geertu> shimoda: Then IMHO ATF should provide the information we need... +10:19 < shimoda> dammsan: I should have descriped such information on my report though... +10:20 < geertu> I think the time has come to conclude the meeting +10:20 < geertu> Annything else to discuss? +10:21 < shimoda> nothing from me +10:21 < geertu> OK +10:21 < geertu> Thanks for joining, and have a nice continued day! +10:22 < dammsan> geertu: AXI bus section has details about memory protection areas =) diff --git a/wiki/Chat_log/20180322-io-chatlog b/wiki/Chat_log/20180322-io-chatlog new file mode 100644 index 0000000..848bf3d --- /dev/null +++ b/wiki/Chat_log/20180322-io-chatlog @@ -0,0 +1,206 @@ +09:01 < wsa_> hiya! +09:02 -!- dammsan [~dammsan@s214090.ppp.asahi-net.or.jp] has joined #periperi +09:03 < jmondi> and now I have received the emails, but still can't send any +09:03 < wsa_> Greetings from snowy Berlin... +09:04 < wsa_> So, Vaishali is not here yet.

Niklas fixed a bad comment in RAVB and reviewed the thermal patches in the BSP. Shimoda-san upstreamed M3-N bindings for Gen3-USB2-PHY and PWM, and also added PM to PWM. Wolfram finished the QEMU-I2C-passthrough research, fixed some issues with QEMU EEPROM emulation, started working into the new upporting list, subitted a talk proposal for AGL, and +09:10 < wsa_> did various reviews discussions, mainly about SDHI and Watchdog. +09:10 < wsa_> B) +09:10 < wsa_> Geert wants to enable MSIOF on M3-N. Niklas wants to upport thermal patches once he gets feedback from BSP team. Shimoda-san wants to research USB role swap issue nad add GPIO support to Gen3-USB2-PHY. Wolfram wants to do more SDHI work (tuning & fast modes), write feedback to the HW team for Gen4, plan new tasks (upporting & additional), and hopes to find some time to finally talk about reprogrammable I2C +09:10 < wsa_> addresses. +09:10 < wsa_> C) +09:10 < wsa_> None +09:11 < wsa_> The summary is missing Simon's and Uli's report which came a bit too close to the deadline +09:11 < uli___> no i/o updates from me +09:12 < wsa_> horms: uli___ : please send them a tad earlier, so I have a chance ;) +09:12 < horms> wsa_: sorry about that +09:12 < horms> It completely slipped my mind +09:12 * geertu hasn't received Simon's and Uli's report yet, blames Gandi +09:12 * morimoto we need to care that non PeriPeri member are joined in periperi-ML.

Probably can be fixed by correctly handling clocks for ES1.0 as the current setup seems to be that of ES2.0. +09:19 < horms> 2) follow-up work required for M3-N +09:19 < wsa_> dammsan: ok, fine. I am still not 100% sure of all the use cases, so we might want to talk about it somewhen to form the next add. tasks? +09:19 < horms> I feel we need a plan to solve 1) first +09:19 < dammsan> wsa_: yeah i think so +09:20 < horms> what is your view of things? +09:20 < wsa_> horms: wasn't it agreed on periperi to drop HS400 for H3 ES1.0? +09:20 < wsa_> let me check... +09:20 < horms> ok, somehow I missed that +09:20 < horms> perhaps we can have a follow-up chat to clarrify +09:20 < horms> basically i'm not clear on the situation and way forwards +09:21 < wsa_> horms: Message-ID: <TY1PR06MB09920F022C0459489E7B34FBD8DA0@TY1PR06MB0992.apcprd06.prod.outlook.com> +09:21 < wsa_> horms: yes, let's do that +09:22 < dammsan> may i chime in +09:22 < wsa_> sure +09:22 < dammsan> just wanted to say that older ES versions may not require the most efficient performance really +09:22 < dammsan> so tracking latest ES version and optimizing those might be a good thing to focus on +09:23 < horms> wsa_: thanks, I see that message. +09:23 < dammsan> i highly doubt that any customer would cry if they had PIO-only for older ES versions +09:23 < Marex> neg: morimoto: thanks ;-) +09:23 < horms> dammsan: thanks, understood. +09:23 < dammsan> thanks guys +09:23 < horms> It seems the proposal from Shimoda-san is not to support HS400 on H3 ES1.x +09:23 < horms> is that acceptable to you? +09:23 < dammsan> for sure +09:23 < horms> Ok, thanks +09:24 < wsa_> I'd favor that, too +09:24 < horms> In that case I think we more or less have a way forwards. Just have to sort out the technical details. +09:24 < horms> There was one more issue relating to where tuning hooks in +09:24 < geertu> As long as we get access to the newer hardware, that's fine (for H3 ES2.0 we have, for H2/M2-W we haven't) +09:24 < horms> I did try the suggestion to move it to the usual place, which failed +09:24 < horms> I think I should try again +09:24 < wsa_> let's talk about this later in #periperi-io after the IO meeting ended (so other ppl can join, too if they want) +09:25 < horms> sure +09:25 < wsa_> thanks! +09:26 < wsa_> so, there have been requests for smaller tasks for Kaneko-san and Vaishali +09:26 < wsa_> I wonder if M3-M enablement would be suitable? +09:26 < wsa_> M3-N +09:26 < wsa_> most (if not all) IO devices are identical to M3-W +09:27 < wsa_> so, I'd think this is a good chance to learn about IP cores from datasheets etc... +09:27 < shimoda> wsa_: enablement means adding bindings and/or adding dts? +09:27 < wsa_> yes +09:27 < wsa_> exactly +09:27 < geertu> enablement means ... + testing +09:28 < wsa_> also true +09:28 < shimoda> wsa_: geertu: i got it. thanks +09:28 < wsa_> which can be done even by remote for quite some IO devices +09:28 < wsa_> but they'd need access to the datasheets +09:29 < wsa_> is it possible? does it make sense? +09:29 < wsa_> it would reduce the periupport list also quite a lot, I'd think :) +09:30 < wsa_> Marex: BTW is there Gen3 WDT support in U-Boot? +09:30 < dammsan> wsa_: there is no NDA in place for Vaishali yet +09:30 < dammsan> wsa_: but remote access is possible +09:31 < geertu> Without NDA, she can access RZ/G1, RZ/A1, and RZ/N1 datasheets +09:31 < wsa_> hmm, well it would be a bit ... difficult ... to add DTS magic number without the datasheet +09:31 < wsa_> horms: what about Kaneko-san? +09:32 < dammsan> geertu: yeah so older devices might be more suitable +09:32 < horms> I have a confidentiality agreement with Kaneko-san +09:32 < wsa_> dammsan: OK +09:32 < horms> which last time we discussed this - a long time ago - was thought to be sufficient +09:33 < wsa_> do you think such tasks are suitable for him? +09:33 < horms> Yes, I think it could work out +09:34 < geertu> horms: Does Kaneko-san have hardware access? +09:35 < horms> no, i assume some sort of remote access could be arranged +09:35 < wsa_> horms: Good news, thanks +09:35 < horms> perferably in Tokyo +09:35 < wsa_> dammsan: do you have some RZ/... boards in your farm? +09:35 < dammsan> i have a genmai boars setup +09:36 < dammsan> and another one in a box +09:36 < dammsan> waiting to get a boot loader +09:36 < wsa_> good, i might have a task for vaishali then where she could use the genmai +09:36 < dammsan> good! +09:36 < dammsan> please contact her +09:37 < wsa_> I will +09:37 < geertu> dammsan: "another one in a box" == rskrza1? +09:37 < dammsan> yep i think so +09:37 < dammsan> and a peach as well +09:37 < wsa_> good +09:38 < wsa_> so, there will be HS400 discussion right after this meeting in #periperi-io and I will contact a few people in private chat about other stuff, too +09:38 < wsa_> that was it from my side +09:38 < wsa_> anything from your side? +09:40 < wsa_> well, then +09:40 < wsa_> I think it is time for core now +09:40 < wsa_> Thanks for this meeting! +09:40 < wsa_> Have fun, Geert! + +==== split out discussion about HS400 follows + +09:43 < wsa_> hiya +09:46 < wsa_> so, about HS400 +09:46 -!- shimoda [~shimoda@relprex2.renesas.com] has joined #periperi-io +09:46 < wsa_> I think we all agreed now to drop HS400 support for ES1.x +09:46 < wsa_> which makes a lot of sense to me +09:47 < wsa_> horms said he would try using the core hook for HS400 preparation again +09:47 < wsa_> that would be really good if it worked out +09:48 <@horms> Ok, I will look into that +09:49 <@horms> Regarding H3 ES1.x, do we have an idea of how to exlude HS400 support for those SoCs?

+09:51 <@horms> ok, could be as easy as that +09:51 <@horms> I'll investigate +09:51 < wsa_> soc_device_match() and disable the capability? +09:51 < wsa_> HS400 capability +09:51 <@horms> Right, I'll look into a good way to use soc_device_match() +09:53 < wsa_> I tend to think we should upstream HS400-M3N-support incrementally +09:53 < wsa_> so we can upstream this series now +09:53 < wsa_> but I am open to other thoughts +10:00 < wsa_> however, we should be prepared for that +10:01 <@horms> wsa_: yes, I think so too +10:01 <@horms> support is present in the BSP +10:01 <@horms> so it doesn't look like a major headache +10:01 <@horms> but it needs something to be based on +10:01 <@horms> and we may as well get the base right first +10:04 < wsa_> the SD clk divider patch belongs to that base, too +10:05 < wsa_> There is still an open issue: +10:05 < wsa_> Message-ID: <20180227215352.gztj6ezjm7wtbm2z@katana> +10:07 < wsa_> shimoda: can you help here? +10:07 < wsa_> I will check the latest BSP code... +10:12 < wsa_> still the same +10:14 <@horms> wsa_: regarding SD clk patch, ack. I think it is fine as-is given that we no longer want to support H3 ES1.x. Do you agree? +10:15 < wsa_> Well, the code matches the data sheet +10:16 < wsa_> However, AFAIU, M3-N tunes with a clock of 100MHz +10:16 < wsa_> I would like to have this confirmed by the HW engineers +10:17 < wsa_> or to be proven wrong :) +10:17 < wsa_> but this M3-N which we agreed to be incremental +10:17 <@horms> Ok, I see +10:17 <@horms> Maybe we can confirm this using the BSP? +10:18 < wsa_> Not sure +10:18 < wsa_> I need to dive in more +10:19 < wsa_> Otherwise, it could just work... but at the speed of 100MHz +10:19 <@horms> Ok, do you think you could look into that? +10:20 < wsa_> This is mainly about asking HW engineers +10:24 <@horms> Ok, but perhaps we can examine the BSP to get some insight? Or do you think the BSP may be wrong in this regard? +10:27 < wsa_> It matches the datasheet +10:27 < wsa_> I don't know if the datasheet is correct +10:27 < wsa_> That's what I want to ask the HW guys :) +10:27 <@horms> Ok, got it +10:31 < shimoda> wsa_: sorry missed your comment, I should check the email of 20180227...? +10:31 <@horms> I will take a break now, should be back soon +10:35 <@horms> back +10:39 < wsa_> shimoda: I think I will rewrite my question in a seperate mail +10:39 < wsa_> shimoda: so you can forward it to HW engineers more easily +10:44 < shimoda> wsa_: i got it.

I'm looking for a way so I don't duplicate work but have no real preference on how the sync is done +11:08 < pinchartl> we can sync up as soon as the BSP analysis is done +11:08 < pinchartl> I won't work on it before next Thursday +11:08 < pinchartl> so we can sync up next Thursday on IRC if you want to have a look already +11:09 < kbingham> What is required to do the BSP analysis ? Just go through each patch and identify /classify ? or is this where Geert's magic script comes in ? +11:10 < pinchartl> kbingham: just going through the patches, yes +11:10 < neg> Sounds like a plan, I will try to get a overview before next week. Next Friday is a public holiday here so I will be offline but sync on Thursday or Monday works for me +11:11 < pinchartl> kbingham: if you have time for that before next Thursday you can coordinate with Niklas +11:11 < kbingham> Ah yes - I almost forgot - we're coming up to easter holidays here too. +11:11 < pinchartl> please avoid classifying the patches twice independently :) +11:11 < neg> pinchartl: :-) +11:11 < kbingham> Ack :) - although perhaps that's a useful verification :D +11:13 < neg> kbingham: I will for a start only look at the VIN and CSI-2 drivers for MM upport and will sync with you if I jump and look at other drivers +11:13 < kbingham> neg: Ack ... perhaps we can use an etherpad or something so we can see eachothers progress in realtime and avoid duplication. +11:14 < pinchartl> kbingham: or just coordinate on IRC ? you might not need to do the work at the same time +11:14 < neg> kbingham: or a clone of periupport so the result is more easly integrated by our mighty group leader +11:15 < kbingham> yup ... however it works ... Haven't seen what's required yet :D +11:15 < kbingham> As long as we sync when we start. +11:17 < pinchartl> jmondi: you also had a question ? +11:17 < jmondi> yup +11:17 < jmondi> very quick and simple +11:17 < jmondi> morimoto: I asked mt9t112 sensor manual, but it's covered by NDA +11:17 < morimoto> yes +11:17 < jmondi> does this NDA extends to Magnus and from Magnus to me? +11:18 < morimoto> Uhm... dificult question. it is too old for us +11:18 < morimoto> and actually +11:18 < morimoto> I don't have this datasheet anymore... +11:18 < jmondi> I don't want to create more paper work for you, or fights with legals for something like this +11:18 < jmondi> ok, problem solved +11:19 < jmondi> morimoto: thanks for looking into it +11:19 < morimoto> sorry I couldn't help you +11:19 < jmondi> no worries! +11:20 < pinchartl> jmondi: is it similar to the MT9T111 ? +11:20 < morimoto> I think these 2 have no big difference +11:20 < dammsan> it's like r8a7795 and r8a7796 +11:21 < pinchartl> http://www.uctronics.com/download/MT9T111_MT9T112_DS_A.pdf +11:21 < dammsan> no big difference +11:21 < jmondi> pinchartl: yes, it's the same driver +11:21 < dammsan> =) +11:21 < pinchartl> does that help ? +11:21 < morimoto> Wow ! open datasheet ! +11:21 < jmondi> pinchartl: thanks, I have that +11:21 < jmondi> there are no registers description there +11:23 < neg> morimoto: at ELC we talked about my renesas-tests repo for automated testing of som IPs that the BSP team might be interested in and I told you I publish that.

Discussion Topics +10:50 < geertu> Shimoda-san would like to know how to add a node for usb2.0 ch3 on H3 ES2.0. +10:50 < geertu> https://patchwork.kernel.org/patch/9980275/ +10:50 < geertu> Enabling this requires flipping a switch, right? +10:50 < neg> kbingham[m]: ping :-) +10:51 < kbingham> neg: pong :D +10:51 < shimoda> geertu: yes. (according to the ML archive and board datasheet) +10:52 < kbingham> So we must chose between ADV748x and USB2 ch3 and boot time somehow. +10:53 < wsa_> a bit like the PCIE/SATA switch maybe? +10:53 < kbingham> We wouldn't be so lucky to be able to read this switch at runtime would we ? +10:55 < geertu> kbingham: I'm afraid not +10:56 < kbingham> So how should this be handled for the generic case - does it need to be some sort of overlay support ? +10:57 < geertu> In upstream DTS, we have to assume a fixed switch configuration. +10:57 < kbingham> And would you like me to do anything in particular in adv748x ? +10:58 < geertu> shimoda: Have you tried my suggestion, of using GP6_3[01] in salvator-common.dtsi, and overriding it in r8a7795-salvator-xs.dtsi? +10:59 < shimoda> geertu: not yet. so, I will try later +11:00 < shimoda> if success, is it acceptable for upstream? +11:00 < geertu> I think so. +11:00 < geertu> IIRC, my suggestion means that everything keeps working as before, and people who want to make use of the extra channel on H3 ES2.0 and Salvator-XS need to flip the switch. +11:01 < geertu> And everything (e.g. ADV7482) still keeps working after that. +11:01 < kbingham> What will be the effect of flipping that switch - and *not* changing the DT ? (i.e. the user doesn't chagne the DT either by overlay or otherwise) +11:01 < kbingham> Will it just be that the USB2 ch3 won't work ? or will it break ADV748x ? +11:01 < geertu> Correction: after the DT change, r8a7796-salvator-xs.dts +11:02 < geertu> \deleteline -) +11:02 < geertu> Correction: after the DT change, ADV7482 will stop working, until the user flips the switch +11:02 < kbingham> Or more specifically - only one of the ADV748x interrupts ? +11:02 < geertu> Flipping the switch and not changing DT will break the ADV7482 interrupt only, which is not yet supported anyway? +11:02 < Marex> geertu: can DTO help here ? +11:03 < Marex> geertu: U-Boot can apply DTOs +11:03 < geertu> So "stop working" really means "yet unsupported ADV7482 interrupt cannot work +11:03 < geertu> ", so it is harmless? +11:03 < kbingham> Ok - so if I make the (not yet implemented) ADV748x hotplug use only the unaffected interrupt - will we be able to support both ADV748x and USB2 ch3 ? +11:04 < geertu> kbingham: I think so. The switch allows to wire both ADV and USB using the new switch setting. +11:05 < geertu> With the old setting it keeps backwards compatibility with Salvator-X, which doesn't have the switch, and doesn't support the extra USB channel. +11:06 < kbingham> Ok - so I think we have a good all round solution there then. I will have to make sure that only the unaffected IRQ is passed to the ADV748x, and the ADV will have to configure that interrupt to handle whatever it needs. As long as that second interrupt is definitely routed in :) +11:07 < geertu> kbingham: I don't think you have to do anything, the interrupt is to be specified in DT. +11:07 < kbingham> geertu: Quite - but the (not yet implemented) adv748x interrupt configuration will have to map to the correct interrupt pin. +11:07 < kbingham> But that's fine - as it will be named. +11:08 < geertu> Naming or not doesn't matter. +11:08 < geertu> The common salvator-common.dtsi would describe the hardwired (Salvator-X) or default switch setting (Salvator-XS) +11:09 < geertu> r8a7795-salvator-xs.dtsi would override the interrupts property to accommodate the changed switch setting +11:09 < geertu> Does it all make sense? +11:10 < kbingham> Sorry - I meant naming for the driver to know which of the two interrupt sources is connected - as it has two which can both be configured for all interrupt reasons I believ. +11:10 < kbingham> It means the AFE(analog) and HDMI would share the interrupt in the ADV748x, which is why I assume they provide two interrupts +11:10 < kbingham> But I don't think its a problem. +11:11 < geertu> In both cases you can use both interrupts +11:12 < geertu> They're just routed to different pairs of pins on the SoC. +11:12 < kbingham> Ah yes - and I just re-read your message above... the changes specfic to -xs will then be handled there. +11:13 < geertu> (Yes, you can use other switch combinations not listed in the table near SW31 ;-) +11:13 < geertu> (those are considered invalid) +11:13 < geertu> Is there anything else to discuss? +11:14 < shimoda> not from me. thanks! +11:14 < kbingham> shimoda: I posted a USB2 crash to linux-renesas-soc ... +11:14 < kbingham> And I've referenced it this morning for you. +11:15 < kbingham> Is it something that you're aware of?

BSP Team Requests +11:39 < pinchartl> - VIN/CSI2 format +11:39 < pinchartl> The VIN driver supports +11:39 < pinchartl> - MEDIA_BUS_FMT_YUYV8_1X16 - MEDIA_BUS_FMT_UYVY8_2X8 - MEDIA_BUS_FMT_RGB888_1X24 - MEDIA_BUS_FMT_UYVY10_2X10 +11:39 < pinchartl> The VIN hardware can also support MEDIA_BUS_FMT_UYVY8_1X16 by using VnMC::YCAL. +11:39 < pinchartl> The CSI2 driver supports +11:39 < pinchartl> - MEDIA_BUS_FMT_RGB888_1X24 - MEDIA_BUS_FMT_UYVY8_1X16 - MEDIA_BUS_FMT_UYVY8_2X8 - MEDIA_BUS_FMT_YUYV10_2X10 +11:39 < pinchartl> The BSP team would like to have support for MEDIA_BUS_FMT_UYVY8_1X16 in VIN and for MEDIA_BUS_FMT_YUYV8_1X16 in CSI-2. Niklas will look into it. +11:40 < pinchartl> neg: morimoto: did I capture the e-mail communication correctly ? +11:40 < neg> yes +11:40 < morimoto> About format, yes +11:40 < morimoto> About mode, I posted use-case +11:41 < pinchartl> - VIN transfer mode +11:41 < pinchartl> Niklas solved the VIN transfer mode switching issue: +11:41 < pinchartl> git://git.ragnatech.se/linux v4l2/next/vin/mode-v2 https://patchwork.linuxtv.org/patch/47929/ +11:41 < pinchartl> The patches will be upstream in v4.17. +11:41 < pinchartl> The BSP team has tested the code and confirmed the issue has been fixed. However, they noticed the disappearance of single capture mode support, and would like that functionality to be restored. +11:41 < pinchartl> Niklas noted that using continuous capture mode unconditionally simplified the driver and improved performances. If single capture mode is needed he isn't opposed to adding it back, but would like to have a clear description of the use cases. +11:41 < morimoto> It seems BSP team doesn't have strong reason +11:41 < pinchartl> ok. I propose continuing the discussion about VIN capture more on the mailing list then +11:41 < pinchartl> morimoto: you posted X-1, X-2 and X-4. is there no X-3 or have I missed it ? +11:42 < dammsan> may i propose "random" capture mode" to make it more exciting? +11:42 < neg> And I can't see a clean/usefull way of readding it other then a sysfs option / module paramater / v4l2 control to force using single capture mode, and all of those solutions seems odd +11:42 < neg> dammsan: I like your style! +11:42 < kbingham> Surely single capture mode is just send one buffer :D +11:43 < neg> kbingham: you need to specify how many buffers the driver wants before a stream can start and currently that is more then one, so no dice :-P +11:43 < pinchartl> neg: I agree with you. I don't see a use case for single capture, as we can capture a single frame even in continuous capture mode, can't we ? +11:43 < morimoto> pinchartl) sorry X- numbering is very random. total tree +11:43 < dammsan> how about using spectre/meltdown utility instead of silly sysfs? +11:43 < kbingham> neg: The driver no longer needs 3 buffers to start :D - (just 3 buffers to capture smoothly) +11:43 < pinchartl> morimoto: no worries, I just wanted to make sure I hadn't missed a X-3 +11:43 < neg> pinchartl: yes, but you still need to queue 4 buffers as min_buffers_needed = 4 +11:44 < pinchartl> did we have a lower minimum number of buffers when we supported single capture mode ? +11:45 < neg> pinchartl: yes, at first submission it was 3 then in a rework where it switched between single and continues capture the minimum was 1 but that led to the performance issue +11:46 < neg> pinchartl: so now with the always continues capture we need 4, which with a bit of work in patches I will submitt after Gen3 support is picked up might be able to be reduced to 3 +11:46 < pinchartl> how about using single capture unconditionally when we have one or two buffers, and continuous capture when we have more ? +11:47 < pinchartl> I mean the number of buffers queued at streamon time +11:47 < pinchartl> that way we could support single capture using a single buffer +11:47 < pinchartl> without having to allocate buffers that will never be used +11:47 < neg> pinchartl: that could work, but then all v4l2 tools would run using single capture as they queue the min buffers needed and then start the stream +11:48 < pinchartl> do drivers report the minimum number of buffers they need ? +11:48 < neg> so to run in continues mode the applicaiton would need to know about this and queue more buffers before starting the stream or have bad performance +11:48 < kbingham> Can the driver report that it needs 4 buffers ... but 'accept' only one ? +11:48 < neg> pinchartl: yes in vb2_queue min_buffers_needed field +11:48 < pinchartl> neg: but that's not reported to userspace is it ? +11:49 < pinchartl> kbingham: I think the only information reported to userspace is through REQBUFS +11:49 < pinchartl> if you ask for less than the minimum, you get the minimum +11:49 < neg> pinchartl: not sure how user-space handles it, but somethigng in the v4l2 framework ensures that numbers of buffers are queued before s_stream is called +11:49 < kbingham> So no then :) +11:50 < pinchartl> if you ask for less than the minimum, you get the minimum +11:50 < pinchartl> oops +11:50 < pinchartl> we might need an API extension there +11:50 < pinchartl> but apart from that, I don't see how we could select between the two +11:51 < pinchartl> I agree that allocating buffers that will never be used is a waste of memory +11:51 < pinchartl> but to be honest, I also think that most use cases will capture video and will wait continuous capture mode +11:52 < neg> Yes, I agree. It's a waste of buffers if you only want to grab one frame but most use-cases IMHO would benefit from continues capture mode +11:53 < pinchartl> I think we could investigate that, but only if there's a real need, as development would require a substantial effort +11:53 < neg> So yes a API extension would probobly be needed if this where to be supported with a user-space interface +11:53 < pinchartl> are we done with this question ? +11:54 < neg> I still don't know if I shall handle this or if we are shelfing it +11:54 < dammsan> i propose shafing or quefing =) +11:54 < morimoto> The conclusion is supporting single mode is difficult at this point, and it needs API extension ? +11:54 < dammsan> instead of shelfing +11:54 < pinchartl> I'll state in the meeting report that we need feedback +11:54 < morimoto> And I think it is not realistic +11:55 < dammsan> please don't include my suggestions in the report +11:55 < neg> morimoto: I still don't understand the use-case, in your reply it only stated that single mode was used before, now it's not but it might be good if it where still an option. But I don't understand why that is :-) +11:55 < neg> dammsan: :-) +11:56 < pinchartl> morimoto: I think the conclusion is that we need an API extension to make real use of single capture mode, it will require substantial development effort, and we should thus only implement it if really needed +11:56 < wsa_> ack on the new meeting date. i can imagine 4pm is way better for JPeri +11:57 < morimoto> BSP team don't know how the customer is using single mode, or not. Their main reason is just simple. They want to keep compatibility, because they doesn't want to update BSP guid pdf :) +11:57 < wsa_> :D +11:57 < morimoto> I think we can drop single mode. what do you think ? +11:58 < pinchartl> morimoto: I think so too +11:58 < pinchartl> - Status of vsp-tests +11:58 < pinchartl> Morimoto-san reported vsp-tests failures on H3 ES1.1 in +11:58 < pinchartl> Subject: Re: [periperi] 2018-03-01 - Group meeting - Infos & Call for updates +11:58 < pinchartl> Date: Thu, 01 Mar 2018 15:50:45 +0900 +11:58 < pinchartl> The issue has been discussed in the multimedia meeting on that day. The BSP team would like a status update. +11:58 < pinchartl> We haven't had time to look into these issues yet, they are still on the to-do list. As far as we understand this isn't urgent, but the priority can be raised if needed. +11:59 < pinchartl> that's all for the BSP team questions +11:59 < morimoto> I think it is not urgent. +11:59 < pinchartl> but today we have a new topic +12:00 < pinchartl> Topic 3. Questions for the BSP Team +12:00 < pinchartl> :-) +12:00 < morimoto> Just checking progress +12:00 < pinchartl> While going through the BSP patches to pick upporting candidate the following questions were raised (for the full discussion see "VIN and CSI-2 Upport" on the periperi mailing list). We would like the BSP team to provide us with information. +12:00 < pinchartl> - rcar-vin: Add memory type of VB_USERPTR support 373b05b01463bfbeca8d6382da29fa038ea4b8e1 +12:00 < pinchartl> Is there a use-case for USERPTR? Niklas has never used it and Laurent explained that there are not many use-cases for this that are not better served by DMABUF. We would like to know more about this use-case before upporting this if possible. +12:00 < pinchartl> - rcar-vin: Add overflow debug message option 4c0da798c52053d5a10e6d74364c12c049af0caa +12:00 < pinchartl> Is there a test-case for this? Are overflows common or is this just some diagnostic help for debugging? If possible it would be useful to know more about the reason for this commit. +12:00 < pinchartl> - rcar-vin: Set MEDIA_LNK_FL_ENABLED by using rvin_get_chsel 29c1ff33427f2c56ccc3dd4a3dd79026b2316f77 +12:00 < pinchartl> Niklas and Laurent discussed this commit and both think this is not suitable for up-porting. The user should enable the links in the pipeline as part of the format configuration before starting a stream. Is there a use-case for this in the BSP which we should consider? How does Renesas feel about dropping this from the BSP ? +12:00 < pinchartl> - media: rcar-csi2: Add blank margin when caluculating bit rate e2f958eedfdcd63145e147f273585a66889fa0db +12:00 < pinchartl> What is the rationale behind this? Is this not a property of the video source and not the CSI-2 receiver? Should not this be included in the V4L2_CID_PIXEL_RATE reported by the source? +12:00 < pinchartl> On the periperi mailing list Niklas reported this should be upported, but Laurent disagreed and explained how it could be a property of the video source instead. +12:00 < pinchartl> - media: rcar-csi2: Fix field detection b6aac9f75929a1ac54e5b026eeb717a7db44aa8e +12:00 < pinchartl> We believe this patch follows a wrong approach. The standard shall not be propagated inside the kernel but be explicitly set by the user for a pipeline which is part of a media graph. Would this change in approach fulfill the use-case which lead to this patch in the BSP? +12:00 < pinchartl> morimoto: all this will be included in the meeting report, I don't expect you to answer right now :-) +12:01 < pinchartl> neg: did I capture all that correctly ? +12:01 < neg> pinchartl: wall of text, reading now :-) +12:01 < pinchartl> for everybody else: if you have any similar question regarding the BSP patches, please send them by e-mail (or ask them now if you want to) +12:03 < neg> pinchartl: looks good +12:03 < kbingham> pinchartl: I sent one question already to Matsuoka-san +12:03 < pinchartl> thank you +12:03 < kbingham> But really all I want to know is from "Re: [periperi] [PATCH] media: i2c: adv748x: Fix video standard selection register setting" if the patch fixes a known issue. +12:03 < morimoto> pinchartl: thanks, I will forward to BSP team +12:04 < kbingham> If it does'nt fix anything then I'll likely drop the patch. +12:04 < pinchartl> kbingham: sounds good to me +12:04 < pinchartl> so that's all for the question to the BSP team +12:04 < pinchartl> the next topic is something you've all been waiting for +12:04 < pinchartl> Topic 4.

In SPL ? earlier ... in bootrom maybe ? +09:50 < wsa_> not ASAP +09:50 < wsa_> it is research +09:50 < Marex> but then what is the point ? the system can hand before WDT is active +09:50 < Marex> *hang +09:50 < geertu> There's also the secure WDT +09:50 < geertu> to be handled by ATF? +09:50 < Marex> geertu: Gen3 only I guess ? +09:51 < geertu> Marex: Gen2 also has SWDT hardware block +09:51 < wsa_> can we just have it for research reasons? +09:51 < Marex> wsa_: what are you attempting to learn from this research ? +09:52 < wsa_> U-Boot <-> Linux handover +09:52 < geertu> FTR, "git grep -i swdt plat/renesas/rcar" reveals ATF has SWDT support +09:52 < Marex> wsa_: anything in particular ? that just seems a bit vague +09:53 < wsa_> it is not +09:53 < wsa_> it is what i want to research +09:53 < Marex> wsa_: well, adding a driver to u-boot is certainly possible +09:54 < Marex> wsa_: and I guess real easy +09:54 < wsa_> either we agree on "sure, let's try" or we agree on "no, we do only full solutions" +09:54 < Marex> wsa_: well said +09:54 < dammsan> but whats the purpose? +09:54 < dammsan> (sorry if i'm being slow) +09:54 < dammsan> cover the entire boot process from as early as possible? +09:55 < wsa_> We need to implement the handover first to get other changes upstream +09:55 < Marex> if that was the case, see my remark about TPL ... and on Gen3, that'd mean handoff from ATF to U-Boot and U-Boot to Linux +09:56 < wsa_> and i thought we could do that since the U-Boot driver would be trivial to add +09:56 < Marex> wsa_: what "other patches" ? +09:56 < Marex> *other changes +09:56 < dammsan> ok, but u-boot is rather late in the boot process +09:56 < dammsan> perhaps the ATF -> U-Boot thingie is similar to the DDR memory topic? +09:57 < dammsan> we need to pass state in both cases +09:57 < wsa_> Marex: proper timer initialization according to documentation +09:58 < geertu> The "receiving" side can easily read the WDT registers to find out if the RWDT is enabled and running. +09:58 < wsa_> upstream rejected the patch as unneeded because we don't handle takeover yet +09:59 < dammsan> so why do we need to block on u-boot then if it is just a matter of reading registers? +09:59 < geertu> wsa_: Which patch was rejected? Do you have a link? +09:59 < wsa_> so i thought we could add that to get the patch upstream and learn about it to get one step closer to having proper WDT support when booting +09:59 < wsa_> but I am about to just give up on that +09:59 < Marex> geertu: was about to ask the same thing , might make it more obvious what the issue is, you were faster +09:59 < dammsan> wsa_: dont give up =) +10:00 < wsa_> [PATCH] watchdog: renesas_wdt: adapt timer setup to recommended procedure +10:01 * Marex reads the discussion there +10:01 < wsa_> but I need to go to the workshop now +10:01 < geertu> wsa_: Thx +10:02 < geertu> Ah, that patch. +10:02 < geertu> IMHO it has only a vague dependency on handover support. +10:02 < geertu> "The only exception I can think of is if the watchdog is +10:02 < geertu> already running during boot, but that situation isn't handled +10:02 < geertu> anyway. +10:02 < geertu> " +10:03 < geertu> Does fixing that need watchdog core support? Or just driver changes? +10:03 < wsa_> That's what I wanted to investigate +10:03 < geertu> ATF SW executive summary: void bl2_swdt_exec() { ... ; panic(); } +10:04 < geertu> s/SW/SWDT/ +10:04 < Marex> looks like a more general issue to me +10:04 < geertu> Well done, ATF! +10:04 < geertu> Sorry, forgot to quote the comment: +10:04 < dammsan> "As expected by The Firmware" +10:04 < geertu> void bl2_swdt_exec() { ... ; /* Endless loop */ panic; } +10:05 < Marex> good thing U-Boot is not firmware , no matter what other people claim +10:05 < Marex> wsa_: so your plan is to fix the WDT core to handle the handoff case proper, right ? +10:05 < Marex> wsa_: and for that you need someone to enable WDT before Linux boots ? +10:05 < wsa_> yes +10:05 < Marex> wsa_: can't you simulate that by poking the WDT registers on the U-Boot command line for now ? +10:06 < geertu> Or in early kernel startup +10:06 < wsa_> sure +10:06 < dammsan> geertu: do we need to preserve clocks during init too? +10:06 < Marex> wsa_: in the boot command even ... setenv bootcmd run wdt boot_linux +10:06 < wsa_> I thought the driver was trivial and U-Boot commands would be easiert to use +10:06 < geertu> dammsan: watchdog needs the clock running. +10:06 < dammsan> or i guess it is always-on 32khz clock that is needed +10:06 < wsa_> If I had foreseen this discussio, I'd surely have gone with poking registers +10:07 < Marex> wsa_: there are no commands for WDT, it just gets poked during U-Boot just like it does during Linux +10:07 < Marex> wsa_: the driver is trivial, sure +10:07 < wsa_> i see +10:07 < Marex> wsa_: but if you just need to fire up the WDT, it is probably trivial-er to just poke the registers +10:07 < wsa_> I agree +10:07 < Marex> but if there is interest in adding the WDT support to U-Boot, that can be done too :) +10:08 < wsa_> so, good outcome of the discussion after all :) +10:08 < Marex> wsa_: indeed! +10:08 < Marex> wsa_: and we untangled the confusion, which is nice +10:08 < wsa_> Yes +10:08 < geertu> dammsan: for RWDT, there's an MSTP bit +10:08 < wsa_> I guess I got a little grumpy because I'll be late for the workshop +10:08 < geertu> for SWDT, there isn't, it runs directly for external OSCCLK +10:09 < wsa_> my apologies for getting grumpy +10:09 < Marex> wsa_: sorry for being a little slow ! +10:09 * geertu has faint memories of an SWDT MSTP bit in an older datasheet +10:11 < geertu> Unless someone has something (short) else to discuss, I think we're finished? +10:11 < geertu> wsa_: Thx, and now run! +10:11 < pinchartl> wsa_: before you run +10:11 < pinchartl> next meeting ? +10:11 < pinchartl> two weeks from now ? +10:12 < wsa_> gotta ack +10:12 < pinchartl> I will be unavailable I'm afraid, but that shouldn't stop anyone from meeting +10:12 < wsa_> ack +10:12 < geertu> pinchartl: Fine for me (for Core) +10:12 < wsa_> 3 weeks would also be fine with me +10:12 < dammsan> 3rd is holiday in japan +10:13 < wsa_> 10th then?

But I also think that its possible that the patches are obviously correct. +09:16 < horms> Depending on their contents, of course. +09:16 < horms> My experience from RAVB +09:16 < horms> is that I was a bit to motivated to flush out the patches for admin/reporting/... reasons +09:16 < horms> and should have paid more attention to upstream requirements - motivation for the patch, relevance to current upstream code, etc... +09:17 < dammsan> horms: glass is half full there =) +09:17 < shimoda> i can ask bsp team about your questions. +09:17 < horms> Yes, then suddenly it was half empty :) +09:18 < dammsan> i would say 50% correct =) +09:18 < shimoda> wsa_: all patches need a test case? +09:18 < dammsan> but i guess it is case by case +09:19 < wsa_> shimoda: this is what I wanted to find out if every patch needs a test case? +09:19 < wsa_> shimoda: so I wanted to know if I2C and SDHI are special or not +09:19 < wsa_> but it seems really case by case +09:20 < wsa_> but in general: the more test-cases (or ways to reproduce) the better +09:21 < wsa_> even if it is just to make sure the issue was not only fixed in the BSP kernel but also in the upstream kernel +09:22 < wsa_> I guess we will see how it goes +09:23 < horms> Right, especially if the patch was made against a v4.9 based BSP, which is rather old by now +09:23 < wsa_> And I need to improve how to ask open questions ;) +09:23 < wsa_> I don't have any other topic +09:24 < wsa_> we don't have add. tasks this quarter and people are busy upporting +09:24 < dammsan> wsa_: why would I2C and SDHI be special? +09:24 < wsa_> no reason +09:24 < wsa_> that's why I asked +09:24 < wsa_> how other ppl would handle this +09:25 < dammsan> i think it is important to take target platform into consideration +09:25 < dammsan> my gut feeling is that BSP folks are focusing on solving the issue in front of them +09:25 < dammsan> and perhaps not thinking how it affects other generatiosn / sooooooooooocs +09:25 < shimoda> about test cases, bsp team described them in internal redmine tickets, but I don't know why but they don't describe into the commit log... +09:26 < shimoda> sometimes i could find the tickets, but +09:26 < shimoda> sometimes i asked bsp team +09:26 < wsa_> shimoda: are they described in Japanese or English? +09:26 < shimoda> of course Japanese :) +09:26 < wsa_> :D +09:27 < wsa_> maybe they could at least add the ticket number to the patch? +09:27 < wsa_> not much to type, but still helpful +09:28 < dammsan> horms: how did you handle things when you felt information was lacking? +09:28 < shimoda> I'm not sure about adding the ticket number. +09:28 < shimoda> anyway I'll ask them. +09:28 < geertu> wsa_: Under the ---, upstream doesn't like private ticket numbers in public commit messages +09:29 < dammsan> geertu: including not-yet-disclosed CVE? =) +09:29 < dammsan> (perhaps thats a different thing) +09:30 < wsa_> geertu: I would consider this part of the upporting work to remove them +09:30 < horms> dammsan: my usual approach is to try to work out what the BSP developer was trying to achieve with a patch.

This issue brings a issue we are already aware of into a critical problem. +10:34 < pinchartl> The patch in question plays with CMA, The technical analysis is currently missing, but the result however is very noticeable. If the format configured in the media graph don't match reality more data then is allocated in the capture buffer can be written to the buffer. This was known before but this change appears to place the capture closer to other data which now easily crashes the whole system. +10:34 < pinchartl> To make matters worse there seems to be no way to set the video standard (PAL/NTSC/..) on a subdevice that is part of a media graph. This currently makes CVBS capture dangerous to to use with anything but a NTSC source as that is the adv748x drivers default standard. Niklas has developed a patch for the kernel subdevice implementation that allows for QUERYSTD, G_STD and S_STD to be controlled as for a +10:34 < pinchartl> video device, similar work have already been done for EDID and other similar IOCTLS. +10:34 < pinchartl> Before posting the patch Niklas wanted to discuss the solution with the multimedia team. As extending the IOCTLS that are allowed for a subdev might be useful the core of the problem is still the same. If the user selects NTSC and feed it a PAL source things will crash which is not really good. One idea is to have the get_fmt/set_fmt of the AFE in the adv748x detect the current standard and return +10:34 < pinchartl> format based on that, but we tried that in the past and it was rejected. +10:35 < dammsan> pinchartl: i want to ask you about ipmmu support at some point +10:35 < pinchartl> dammsan: sure, let's discuss that after the status update +10:35 < pinchartl> neg: any comment on done/todo ? +10:36 < pinchartl> have we lost Niklas ? +10:37 < pinchartl> seems so +10:37 < dammsan> pinchartl: just fyi there is a measels outbreak in okinawa now +10:37 < pinchartl> I'll reply to his issue by e-mail then +10:37 < pinchartl> dammsan: lovely... +10:38 < dammsan> you might want to get a vaccine if you are not covered already +10:38 < pinchartl> I think I got vaccinated when I was a kid +10:38 < dammsan> our generation of japanese are not fully vaccinated unfortunately +10:38 < dammsan> so it seems to be a bit of a mess +10:39 < dammsan> so i would enjoy seeing you _before_ your okinawa trip +10:39 < geertu> pinchartl: As a Belgian, you should have gotten either the disease, or the vaccine. +10:40 < jmondi> I got vaccinated when I was a kid, but they gave me another shot before I left for thailand +10:40 < pinchartl> dammsan: I'm afraid that would be difficult :-/ +10:41 < dammsan> might be good to be careful +10:41 < jmondi> pinchartl: you may want to ask, they told me the new raccomandation is to have 4 shots not just 3 as it used to +10:41 < dammsan> pinchartl: yeah +10:41 < pinchartl> as I'll land on the 30th in the morning in Narita and leave from Haneda on the same day in the afternoon +10:41 < jmondi> ofc you'll be autistic after that according to novax.info and other reliable sources +10:42 < dammsan> pinchartl: maybe we can meet at haneda? +10:42 < geertu> jmondi: Only 2 shots for my kids, according to their vaccination card. +10:42 < dammsan> anyway lets discuss later +10:42 < pinchartl> dammsan: :-) +10:42 < pinchartl> so neg is absent +10:42 < pinchartl> let's move on +10:43 < pinchartl> Topic 2.

+09:56 < geertu> dammsan: I think partition info in DTS is fragile +09:56 < dammsan> for sure +09:56 < dammsan> so where to put it? +09:57 < geertu> While even you don't really use the FLASH, you do want to have the partition info, so you can run a FLASH test on Linux (read-only everywhere, write to all but the boot loader partition) +09:57 < Marex> mtdparts on kernel command line ? +09:57 < geertu> s/even/even if/ +09:57 < Marex> with the first 1 MiB marked ro ? +09:58 < geertu> Marex: That's not sufficiently safe, IMHO +09:58 < dammsan> makes sense +09:58 < geertu> First MiB marked ro sounds good to me +09:58 < geertu> Marex: I mean that I regularly boot kernels with +09:58 < geertu> CONFIG_CMDLINE="ignore_loglevel root=/dev/ram" +09:59 < geertu> CONFIG_CMDLINE_FORCE=y +09:59 < geertu> (for using initrd on remote boards) +09:59 < dammsan> i suppose there is no way we can store a partition table somewhere? +09:59 < dammsan> one physical sector minimum per copy, 2 copies +09:59 < geertu> So the partition info must be stored in the board-spcific part +09:59 < geertu> dammsan: yes we can. +10:00 < dammsan> since it is a runtime configuration item it makes sense to separate that from DTS +10:00 < geertu> dammsan: We do have the SPI loader in the first 16KiB, but some partitioning schemes can have the part table elsewhere (not at the start of the device_ +10:00 < dammsan> aligning to the end of the flash?

[PATCH/RFC] ARM: shmobile: defconfig: Enable LPAE +10:04 < geertu> (https://www.spinics.net/lists/arm-kernel/msg648585.html) +10:05 < dammsan> i think for 32-bit arm we need two configs +10:05 < dammsan> if we should bother about lpae +10:05 < horms> This is not the first time this has come up +10:05 < geertu> The RZ/G1 crew wants to have LPAE enabled, but that's incompatible with older SoCss +10:05 < geertu> Indeed, multi_v7_defconfig also doesn't have LPAE because of that +10:05 < Marex> geertu: so what is the decision ? +10:05 < horms> The last time, iirc, the answer was it'll all be awesome with fragments +10:05 < horms> but I guess fragments never got committed to mainline +10:05 < Marex> geertu: U-Boot generally uses mtdparts and I dont think it supports any of this partitioning stuff in flash ... +10:06 < geertu> Marex: On-FLASH partition table? +10:06 < Marex> geertu: I see, I don't think U-Boot supports it, so I'd have to check how that can be added +10:06 < dammsan> Marek: please +10:07 < geertu> horms: kernel/configs/ has some fragments +10:07 < horms> ok, can we add an lpae fragment? +10:07 < Marex> geertu: also, noone really uses that sort of thing, the systems I am aware of all use mtdparts passing on the kernel command line +10:07 < horms> would that solve the problem? +10:07 < horms> would it be more than one line long? +10:07 < geertu> I guess so, and Arnd will be happy, too, if it can be used with e.g. multi_v7_defconfig, too +10:07 < Marex> geertu: I guess we can have our special solution though +10:07 < Marex> dammsan: yes ? +10:08 < geertu> Marex: From one side, if everybody else uses mtdparts, I thinkl we should use it, too. +10:08 < dammsan> Marex: seems both geertu and i like the idea of on-flash partition table +10:08 < horms> geertu: ok, then I suggest we try that. I could make a patch and the RZ/G guys could test it. +10:08 < geertu> But there are too many use cases for kernels that cannot receive bootargs from U-Boot (uImage/zImage with appeneded DTB, CONFIG_CMDLINE_FORCE, ...) +10:09 < Marex> dammsan: then again, everyone else uses mtdparts and I have yet to see a recent system with on-flash partition table +10:09 < dammsan> sure +10:10 < dammsan> just feels like a sane thing to move towards +10:10 < dammsan> but the offset for the partition table needs to be described somewhere +10:10 < geertu> Given the SPI loader is 16 KiB, but the block size is 64 KiB, you have 48 KiB for partitioning? +10:10 < dammsan> both for U-Boot and Linux +10:11 < dammsan> geertu: we probably want dedicated physical sectors? +10:11 < dammsan> to be more fail safe +10:11 < geertu> dammsan: That's safer, yes +10:11 < Marex> dammsan: it wastes another sector of the SPI NOR too +10:11 < Marex> dammsan: while if it's in mtdparts, it could be stored alongside the other U-Boot environment +10:12 < dammsan> true +10:12 < dammsan> not having it in DTS must be good at least +10:12 < dammsan> we can agree on that +10:12 < Marex> and you can adjust it in U-Boot with setenv mtdparts instead of having a custom solution in some sector with custom command to set it up +10:12 < Marex> yes, it doesn't describe hardware, it shouldn't be in DT +10:12 < dammsan> sure makes sense +10:13 < dammsan> so how to move forward? +10:14 < dammsan> 1. remove DTS partion info from upstream +10:14 < Marex> I think U-Boot could be tweaked to pass mtdparts via bootargs automatically, which would solve geerts's problem with custom bootargs without mtdparts ? +10:14 < geertu> Marex: Nope, U-Boot cannot pass bootargs with uImage/zImage with appeneded DTB, or CONFIG_CMDLINE_FORCE +10:14 < dammsan> geertu: i understand your problem +10:15 < Marex> geertu: assume mainline U-Boot, which yes, can, if you don't use the uImage/zImage hack +10:15 < dammsan> but would on-flash partition help in such case? +10:15 < geertu> Marex: uImage/zImage with appeneded DTB is indeed mainly a workaround for old U-Boot +10:15 < geertu> Marex: CONFIG_CMDLINE_FORCE is a workaround for people changing bootargs on shared boards in a farm +10:16 < geertu> Although I could just add a "setenv bootargs" to my scripts +10:16 < geertu> Anyway, we ran out of time (no pinchartl to kick us out ;-) +10:17 * Marex gotta run too to make it for the train +10:18 < geertu> Anything else to discuss?

Status updates +09:32 < geertu> A) What have we done since last time: +09:32 < geertu> Kaneko-san posted M3-N thermal support v4. +09:32 < geertu> Marek worked on Linux (PCIe and DA9063L support, dropped mtdparts from +09:32 < geertu> DT) and U-Boot (Blanche and I2C DM/DT conversion, PFC cleanups, xHCI +09:32 < geertu> fixes). +09:32 < geertu> Morimoto-san is happily hacking periject. +09:32 < geertu> Niklas added I2C support to M3-N PFC. +09:32 < geertu> Shimoda-san resubmitted E3 SYSC (incl. ES1.0 workaround), and upported +09:32 < geertu> E3 PFC and GPIO support. +09:32 < geertu> Ulrich posted DMAC bindings upports. +09:32 < geertu> Geert did some Periupport analysis and upporting, sent clk/pfc pull +09:32 < geertu> requests, assisted Gilad with H3 CryptoCell support, and removed legacy +09:32 < geertu> SMP fallback for H2 and M2-W. +09:33 < geertu> B) What we plan to do till next time: +09:33 < geertu> Kaneko-san will upport M3-N WDT support. +09:33 < geertu> Marek will handle PCIe suspend/resume for Linux, and automatic mtdparts +09:33 < geertu> bootargs on U-Boot. +09:33 < geertu> Morimoto-san will enhance periject based on feedback. +09:33 < geertu> Niklas will investigate pinctrl problems on V3M. +09:33 < geertu> Shimoda-san will upport USB2.0 PFC for E3, and pave the way forward +09:33 < geertu> for IPMMU. +09:33 < geertu> Ulrich will work on memory size detection for Gen3. +09:33 < geertu> Geert will review the RZ/N1 clock driver, do more periupport analysis +09:33 < geertu> and upporting, and handle CPG/MSSR and SYSC errata. +09:34 < geertu> C) Problems we have currently: +09:34 < geertu> Morimoto-san wants more periject feedback. +09:34 < geertu> Anything I missed? +09:35 < Marex> geertu: I did some gen3 JTAG digging yesterday +09:35 < Marex> geertu: on S-X, I observe the problem that reset halt doesn't halt the platform, I want to dig deeper at some point +09:36 < geertu> Marex: Halt is implemented by the BD9571 +09:36 < Marex> this would help me restore U-Boot on those platforms over JTAG, which in turn would be useful for U-Boot CIing +09:36 < Marex> geertu: reset halt in OpenOCD is what I mean +09:36 < geertu> Marex: what's is it supposed to do then? +09:37 < Marex> geertu: reset the CPU core and stop execution at the reset vector +09:37 < dammsan> could be power domain related +09:38 < Marex> dammsan: possibly, or it'll need similar funny hack as Gen2 (although I tried that and it didnt immediatelly work) +09:38 < Marex> like I said, I need to dig deeper +09:40 < geertu> OK, keep up the good work! +09:40 < dammsan> Marex: will you be able to look into OpenOCD support while you have physical board access in Tokyo? +09:40 < dammsan> in case it is applicable +09:40 < Marex> dammsan: I have physical Gen3 board here :-) +09:41 < Marex> dammsan: I can look into it now if it's desired +09:41 < dammsan> actually i was thinking of gen2 more +09:41 < Marex> dammsan: Gen2 JTAG is fine, Gen3 has this reset issue and isn't upstream +09:41 < dammsan> fore more complete support +09:41 < Marex> dammsan: Gen2 is partly upstream, board support is submitted and pending application, will be in OpenOCD 0.11 according to latest intel +09:42 < dammsan> cool +09:42 < dammsan> shall i bring e2 silk? =) +09:42 < Marex> if you want more Gen2 boards in OpenOCD, sure, why not :) +09:42 < Marex> dammsan: I have E2 silk on my desk and the board support is submitted, hehe +09:42 < dammsan> alright then i will shut up +09:42 < dammsan> let me know if you need some board +09:43 < Marex> http://openocd.zylin.com/#/c/4532/ +09:43 < Marex> dammsan: Silk, Porter, Stout are submitted, just let me know what other board you want in :-) +09:43 < kbingham> Marex, Did you post the Gen3?

Discussion Topics +09:52 < geertu> a. Should we implement platform_driver.shutdown() on each device driver +09:52 < geertu> (especially for master IPs)? +09:52 < geertu> This is a question from BSP team, relayed through Shimoda-san +09:53 < geertu> Apparently Morimoto-san will steal the show and explain the rationale behind it? +09:53 < shimoda_cloud> Morimoto-san had a related question. but he can reply by himself :) +09:53 < shimoda_cloud> but, I'd still would like to get your opinion about this topic +09:54 < dammsan> yes? +09:54 < geertu> What's the use case? What do you want to do in .shutdown()? +09:55 * geertu tries to keep computers running all the time ;-) +09:55 < shimoda_cloud> background: If Linux system reboots, IPL do that. +09:56 < geertu> shimoda_cloud: What do you mean with "IPL do that"? +09:56 < shimoda_cloud> if IPL changes the DDR setting to "self refresh" and a master IPs are still running, the HW causes to access DDR +09:56 < shimoda_cloud> greetu: Gen3 ATR will access PMIC to reboot, IIUC +09:57 < shimoda_cloud> in this case, Gen3 SoCs will stuck because the DDR is in self refresh mode +09:57 < shimoda_cloud> To stop the HW, BSP team decide to add .shutdown ops to the DU driver +09:58 < geertu> BTW, what's ATR? ATF? +09:58 < shimoda_cloud> But, BSP team would like to know all drivers should have same way or not. +09:59 < shimoda_cloud> geertu: oops, ATF (arm-trusted-firmware) +09:59 < Marex> shimoda_cloud: what problem are you trying to solve by this ? +10:00 < dammsan> bus mastering devices are still running when firmware is entering self refresh +10:00 < Marex> ah +10:00 < shimoda_cloud> Marex: I'm not trying to solve this now. But, I'd like to give BSP team about upstream team's policy +10:00 < dammsan> the subsystem is not involved somehow? +10:00 < shimoda_cloud> dammsan: thanks for simple explanation :) +10:01 < dammsan> np +10:01 < geertu> And devices aren't stopped elseway before reboot? +10:02 < shimoda_cloud> geertu: indeed +10:03 < Marex> shouldnt the reboot put the system into defined state ? +10:03 < Marex> q2: doesnt the dram enter self-refresh only during suspend ? +10:03 < Marex> bbiab +10:03 < shimoda_cloud> dammsan: i checked roughly yesterday, but the subsystem doesn't have any solutions, I think +10:04 < geertu> Devices are suspended during system reboot +10:04 < geertu> Ah, DU doesn't have Runtime PM support yet? +10:06 < pinchartl> geertu: DU has complex clock handling requirements +10:06 < geertu> E.g. for sh_eth on Koelsch, genpd_stop_dev() is called before reboot (I still have some local debug code that tells me) +10:06 < pinchartl> runtime PM is not on the high priority list +10:06 < dammsan> that would make sense +10:06 < geertu> pinchartl: I know ;-) +10:07 < shimoda_cloud> geertu: thanks for the information about Runtime PM. This is easy to know which drivers needs for .shutdown() +10:08 < shimoda_cloud> s/needs for/needs/ +10:08 < dammsan> shimoda_cloud: is Runtime PM BSP-first? +10:09 < dammsan> the dependencies between different DU devices seem quite complex to me +10:11 < shimoda_cloud> dammsan: IIUC, almost all drivers have already supported Runtime PM +10:12 < geertu> The DU node in DT also doesn't have a power-domains property. +10:12 < dammsan> it would be good to fix that +10:13 < shimoda_cloud> some drivers (e.g. ehci-platform) lack Runtime PM though... +10:13 < geertu> Yep, separate device nodes for each channel, linked with "companion" properties +10:13 < dammsan> can't we have bus notifier in soc code to handle PM in such case? +10:16 < dammsan> BUS_NOTIFY_BIND_DRIVER +10:16 < dammsan> and a white list +10:16 < geertu> dammsan: That feels like the legacy clock domain to me... +10:16 < dammsan> as a temporary solution +10:16 < dammsan> might be better +10:17 < dammsan> i guess fixing up DT can be separated from actual SW implementation +10:18 < geertu> We've slowly entered MultiMedia space... +10:18 < pinchartl> let me know when you'll have fully entered multimedia space and I'll take over :-) +10:19 < geertu> I think we have, unless there's another core topic to discuss? +10:19 < pinchartl> (you have 60s, the tea water is heating up) +10:19 < shimoda_cloud> thanks! I have no core topic from my side +10:20 < kbingham> Except I was going to ask about DMAC virtualisation :) +10:20 < pinchartl> (which always reminds me of the 御茶ノ水 metro station in Tōkyō) +10:21 < pinchartl> kbingham: please go ahead +10:21 < dammsan> kbingham: seems like an important topic +10:22 < kbingham> dammsan, geertu: mainly - what's the method of use-case testing. +10:22 < dammsan> sertest inside the guest using a loopback? =) +10:22 < dammsan> not sure if it makes sense +10:23 < kbingham> dammsan, From multiple guests ? +10:23 < dammsan> i think testing a single guest is enough, but designing code for multi-guest +10:24 < kbingham> Ok so just exposing two serial devices into the guest - which then have a loopback. +10:24 < dammsan> for instance +10:24 < geertu> kbingham: That needs wiring. +10:24 < kbingham> geertu, It's the wiring that confuses me ... +10:24 < dammsan> something very basic is also ok with me +10:24 < geertu> Can't you just use the second serial port (debug serial) +10:25 < geertu> Tie it to USB, and you can talk to it from the host +10:25 < dammsan> that seems even better +10:25 < kbingham> as the serial ports on salvatorx are USB gadgets :) +10:25 < kbingham> Ok - so just take the serial and use it as a serial device :) +10:25 < kbingham> (as a usb serial device) +10:26 < geertu> Once it works, you can use that serial as the console for the guest +10:26 < geertu> And wire it up in your farm ;) +10:27 < dammsan> it is hard to beat virsh console +10:27 < dammsan> but hey +10:28 < dammsan> using the second debug serial console sounds great +10:28 < dammsan> if it supports SYS-DMAC that is +10:28 < kbingham> Is USB already supported through the guest ? +10:28 < kbingham> Or does it just do high level USB passthrough ... +10:29 < geertu> kbingham: Use USB on the host, please ;-) +10:29 < kbingham> (or in your test, do you mean then read the 'guest serial' on the 'host USB serial' +10:29 < kbingham> Ok - that's clearer - I thought this was some loopback out of the guest, then back into the guest. +10:30 < kbingham> Ok - well until I dive in and hit problems that's enough for me :) +10:30 < geertu> kbingham: You can also run https://github.com/geertu/sertest on the guest, and on the host +10:31 < geertu> guest=SCIF1 host=cp210x-usb-serial +10:32 < kbingham> geertu, Thanks for the sertest link - I'll get that going too. +10:33 < kbingham> Final question - was it left that I am writing the task description? +10:34 * kbingham was expecting to receive a description ... but that may not be the case +10:34 < geertu> I think so +10:34 < kbingham> geertu, Ok - I'll pull something together and run it past you. +10:34 < geertu> kbingham: Thanks! +10:35 < dammsan> thanks guys +10:35 < geertu> pinchartl: FFWD to MM?

I think we need to move it to core, and from there decide how to proceed. +09:10 < wsa_> geertu: do you agree? +09:10 < wsa_> pinchartl: yes +09:10 < pinchartl> wsa_: there was a budget of 5 days of additional tasks for Q2/2 that we couldn't use as no small task enough I proposed was deemed good enough by Renesas +09:10 < pinchartl> but I suspect you may want more than 5 days :-) +09:10 < Marex> wsa_: I am fine either way +09:10 < geertu> wsa_: OK +09:11 < Marex> wsa_: btw I discovered another bug in the PCIe driver dragged in by Sergei's PHY addition, fixing it now +09:11 < wsa_> Marex: nice +09:12 < wsa_> pinchartl: dunno if we can do it as additional task. AFAIU all our base time was increased to upport. And this is a upport task. +09:12 < wsa_> dammsan: what do you think? +09:12 < neg> My view is that with the VIN lump of lard behind me I will have more time for IO, not sure if pinchartl have something lined up. From a status of pending patches I feel I'm in a better position today then last meeting +09:13 < wsa_> neg: congrats again for getting "rid" of the VIN stuff, that's for sure! +09:13 < pinchartl> neg: for the rest of Q2, I'd like you to keep track of all pending VIN patches to make sure they all get merged +09:13 < dammsan> wsa_: lets use base time as much as possible +09:13 < pinchartl> which involves reposting patches that were delayed due to VIN/CSI-2 being out-of-tree +09:14 < pinchartl> apart from that, I'd like to continue GMSL development, but I think that can wait for Q3 +09:14 < wsa_> sounds good to me +09:15 < wsa_> neg: you fine with that, too? +09:17 < neg> wsa_: I'm not sure what the conclusion is :-) For Q2 I will sheperone delayed patches and focus on SDHI. While in Q3 GMSL might be back to drag me back more to MM? If so I'm fine with it +09:17 < wsa_> that's at least my understanding, too +09:17 < wsa_> pinchartl: d'accord? +09:18 < pinchartl> that's my understanding too :-) +09:18 < pinchartl> if that's fine with you +09:18 < wsa_> \o/ +09:18 < wsa_> perfect, thank you! +09:19 < wsa_> Then, I have a question about E3 upporting/enablement +09:19 < wsa_> Who has HW to test? +09:19 < wsa_> https://osdr.renesas.com/projects/linux-kernel-development/wiki/Hardware is empty on that one +09:19 < geertu> wsa_: Shimoda-san only? +09:19 < wsa_> (BTW I sorted this page a little more) +09:20 < wsa_> I see +09:20 < shimoda_cloud> yes, i have a board only. i'll get more boards later (early July?) +09:21 < Marex> wsa_: I want to lend the board while Im in Japan so I can try U-Boot on it :) +09:21 < wsa_> ah, that's good to know +09:21 < wsa_> so, only trivial binding updates for now +09:21 < Marex> shimoda_cloud: would that work for you for a few days ? I'll arrive on the 13th in the morning +09:23 < wsa_> ok, I will contact some of you individually, too, for discussing upporting details +09:23 < wsa_> other than that, I have nore more topics +09:24 < shimoda_cloud> Marex: that work means U-Boot? I think I (or Magnus-san) can bring the board for you for a few days +09:24 < wsa_> Is there something from your side? +09:24 < dammsan> shimoda_cloud: my plan is to disconnect the E3 board from remote access when Marex arrives +09:24 < Marex> shimoda_cloud: jupp :) +09:25 < Marex> shimoda_cloud: I have the U-Boot patchset kinda ready, so I'll just need to iron out the details on that board +09:25 < shimoda_cloud> dammsan: Marex: I got it :) +09:25 < wsa_> If not, we could switch to core with the added topic of 32bit DMA +09:25 < Marex> shimoda_cloud: I hope for no big surprises, but we'll see +09:26 < geertu> dammsan: You mean the E3 is in your farm? And perhaps available? +09:26 < dammsan> geertu: will be next week +09:26 < geertu> wsa_: SDHI write protect +09:26 < geertu> Is this a regression? SDHI was refactored recently. +09:26 < shimoda_cloud> Marex: I also hope so +09:27 < wsa_> geertu: yes, it is. I am still puzzled because I am sure I tested Yamada-sans patches on Gen3 and Lager. +09:27 < wsa_> and my fixup of that +09:28 < Marex> shimoda_cloud: speaking of which, do you or renesas have a few spare JTAG adapters from Tokyo Eletech for ULCBs ? :) +09:28 < Marex> shimoda_cloud: or can they be bought somewhere in tokyo on the market ? +09:28 < geertu> Marex: "somewhere" == "Akihabara"? +09:29 < shimoda_cloud> Marex: I'll ask goda-san about the adapter +09:29 < Marex> shimoda_cloud: that'd be real nice, but no stress, it's just my curiosity :-) +09:29 < Marex> shimoda_cloud: thank you! +09:30 < wsa_> so, geertu, takeover? +09:31 < geertu> wsa_: OK, thank you! +09:31 < wsa_> have fun. and thanks all for this meeting diff --git a/wiki/Chat_log/20180524-mm-chatlog b/wiki/Chat_log/20180524-mm-chatlog new file mode 100644 index 0000000..4af076c --- /dev/null +++ b/wiki/Chat_log/20180524-mm-chatlog @@ -0,0 +1,126 @@ +Multimedia-chat-meeting-2018-05-24 + +10:36 < pinchartl> welcome to the multimedia meeting +10:36 < pinchartl> let's start as usual with status updates +10:36 < pinchartl> * Jacopo +10:36 < pinchartl> Since last meeting: +10:36 < pinchartl> - VIN parallel input support + Draak VIN support (4 iterations) +10:36 < pinchartl> - VIN endpoint cleanups +10:36 < pinchartl> - Miscellaneous CEU patches +10:36 < pinchartl> - Patch review +10:36 < pinchartl> Until next meeting: +10:36 < pinchartl> - Have VIN parallel merged + Draak VIN enable +10:36 < pinchartl> - Still have to make MT9T111 work with an ARM SoC +10:36 < pinchartl> - soc_camera still needs to be removed +10:36 < pinchartl> Issues and Blockers: None +10:36 < pinchartl> jmondi: any comment ? +10:37 < pinchartl> have you solved the D3 Draak hangs while capturing with v4.17 ? +10:37 < jmondi> only that I have sent a wrong patch name in the activity report +10:38 < jmondi> yes, that was due to the crop issue that was takled in v1, and then more opportunely by Niklas in a follow up patch +10:38 < pinchartl> thank you +10:38 < pinchartl> feel free to reply to the e-mail report with the correct patch name +10:38 < pinchartl> * Kieran +10:38 < pinchartl> Since last meeting: +10:38 < pinchartl> - Supported HDMI on KF issue in #linux-renesas-soc +10:38 < pinchartl> - TLB-Optimise v10, v11 (finally finished I think) +10:38 < pinchartl> - DU Interlaced rebased on top of latest TLB-Optimise +10:38 < pinchartl> - DRM fix patch reviews and testing +10:38 < pinchartl> - Built QEmu for AT +10:38 < pinchartl> Until next meeting: +10:38 < pinchartl> - DMA Virtualisation +10:38 < pinchartl> - Chase up DU Interlaced review +10:38 < pinchartl> Issues and blockers: None +10:38 < jmondi> yeah, no biggies +10:38 < pinchartl> kbingham: any comment ? +10:39 < kbingham> Nope.

So, i intend to use DIP-SW gpio instead of actual ID signal to develop :) +09:10 < geertu> If a SoC revision check is needed later, it can be easily handled by taking the (pointer to) the features) from soc_device_match()->data +09:10 < wsa_> shimoda: role-DIP-switch, nice :D +09:11 < Marex> shimoda: can't you use hotair and replace the connector ? :) +09:11 < geertu> horms: drivers/media/platform/rcar-vin/rcar-core.c is a nice example: +09:11 < geertu> vin->info = of_device_get_match_data(&pdev->dev); +09:11 < geertu> attr = soc_device_match(r8a7795es1); +09:11 < geertu> if (attr) +09:11 < geertu> vin->info = attr->data; +09:12 < wsa_> so, with me being on the road already... +09:12 < shimoda> wsa_: :D +09:12 < wsa_> dammsan: can you give me remote access to H3 ES2.0 Salvator-XS? So, I can check stuff remote at least +09:13 < shimoda> Marex: it's difficult to me (my skill and Renesas office rule) +09:13 < horms> geertu: I am confused now. I see that is an exmple of using soc_device_match. And indeed there are already examples in the SDHI driver. But I thought that we decided to use compat strings for the case in question? +09:13 < geertu> horms: You can start with of_device_get_match_data() +09:14 < Marex> shimoda: ah :) +09:14 < geertu> If needed later, you add the next 3 lines enabling soc_device_match(), but needing no further driver logic change +09:14 < horms> Oh, I see. Very nice. +09:15 < wsa_> So, anything more from your side about the status updates? +09:16 < Marex> wsa_: PCIe32 got one reply ! +09:16 < wsa_> \o/ +09:16 < Marex> wsa_: and I keep resubmitting DA9063L patchset +09:17 < wsa_> Maybe some of the ARM core people are in Tokyo? It seems fastest to me to poke them personally, or get the right group together there... +09:17 < Marex> wsa_: let's see what happens at OSSJ ? +09:18 < Marex> wsa_: although, I doubt that +09:18 < wsa_> I share that feeling, but let's hope a bit... +09:18 < wsa_> okay, for the topic, there is only "add. tasks" from my side +09:18 < wsa_> although there is not much change for the IO group +09:19 < wsa_> pinchartl: notification for you :) +09:19 < wsa_> the focus is still on upporting and we should have increased base time for that +09:19 < wsa_> I'll contact you about upporting individually +09:19 < pinchartl> wsa_: I'm here :-) +09:20 < pinchartl> dammsan: ping +09:20 < pinchartl> we're missing Morimoto-san +09:20 < pinchartl> kbingham: ping +09:20 < wsa_> Add. tasks are possible on request which then are discussed by Renesas +09:20 < dammsan> wsa_: port 9006 is yours +09:20 < wsa_> but no request was made to me, and I don't see one urgent in my list +09:20 < wsa_> dammsan: thanks! +09:21 < kbingham> hola +09:21 < dammsan> pinchartl: whatsup? +09:21 < wsa_> so, doesn't look like add. tasks for IO +09:22 < shimoda> pinchartl: Morimoto-san has a trouble about his PC network setting on Ubuntu 18 :) +09:22 < wsa_> dammsan: unless there is something new I don't know up to now? :) +09:22 < pinchartl> dammsan: Wolfram mentioned additional tasks +09:22 < pinchartl> I requested that to be added to the agenda +09:22 < pinchartl> as this topic concerns all groups, should we discuss it now ? +09:23 < wsa_> Frankly, I am more interested in the base time distribution again +09:23 < dammsan> sure what do you want to know? +09:24 < pinchartl> dammsan: I want to know how we can get additional tasks working +09:24 < pinchartl> as in scheduled in time +09:24 < wsa_> horms: I assume you are so busy backporting LTSI that ravb upporting had to stand back? +09:24 < pinchartl> and not repeat the Q2.2 fiasco +09:24 < dammsan> well i think we need to do two things: +09:24 < pinchartl> we've had a lengthy e-mail discussion but that wasn't public, so I'd like to broaden the audience as I don't think I'm the only one to be bothered by this +09:24 < dammsan> 1) agree on quarterly schedule for meeting dates and additional due dates first +09:25 < horms> wsa_: correct +09:25 < shimoda> wsa_: after discuss about add. task, I'd like to ask you about i2c recovery. Did you see any issues (e.g. write data to a slave wronglty) on your R-Car environment? +09:25 < dammsan> 2) do task break out ahead of time +09:25 < horms> wsa_: also, I think that the ravb backporting is a very low yeild exercise +09:25 < dammsan> pinchartl: who else is bothered? +09:25 < pinchartl> kbingham: the mic is yours :-) +09:26 * kbingham has just about caught up wit hthe mornings mails ... +09:26 < pinchartl> who thinks additional tasks work just fine, and who tihnk they don't ? +09:26 < pinchartl> s/tihnk/thinks/ +09:26 < wsa_> shimoda: sure! +09:26 < kbingham> dammsan, I agree where you said this needs an F2F ... and fortunately one is coming up :) +09:26 < kbingham> Lets make sure we have time :) +09:26 < wsa_> horms: "low yield" means most patches are not suitable for upstream? +09:26 < dammsan> unfortunately not all members are present +09:27 < geertu> Personally, I've never been a big fan of additional tasks. +09:27 < horms> wsa_: yes, I think so +09:27 < horms> But I'll go over them again +09:27 < kbingham> Essentially - for me -the *big* problem is the 'rigid square wave workload' which it causes me. +09:27 < pinchartl> I've never been a big fan of additional tasks either. they were a minor nuisance when they were introduced, but they got more and more annoying over time as they got split in two batches per quarter, and we always got late negotiating them +09:28 < wsa_> "square wave workload" :D +09:28 < kbingham> But in particular - where the due dates are fixed, but tasks are always started late. +09:28 < kbingham> I realise that this last AT is a bit of a special case - but my concerns with planning have started long before. +09:28 < uli___> if i may weigh in: i like that additional tasks tell me what to do; i'm not a self-starter when it comes to work... +09:29 < uli___> the contractual framework is secondary to me +09:29 < kbingham> And it's just this one has been a cliff-edge drop for me :( +09:29 < geertu> kbingham: One very important thing to consider is that this is a prototype +09:29 < dammsan> so historically they were created to allow lower latency operation for our group +09:29 < geertu> which means many more unknowns than "normal" additional tasks +09:30 < dammsan> as opposed to have all the fixed tasks agreed on 3 months ahead +09:30 < pinchartl> dammsan: they have created a much higher latency +09:30 < geertu> IMHO they increase latency. +09:30 < dammsan> sure +09:30 < dammsan> but how can we keep the quality and perform development (not single patch wanking) and reduce paper work? +09:30 < geertu> If something is urgent, there may not be any base time available at that moment, as ATs have a fixed deadline, and thus preempt any base work +09:31 < kbingham> uli___, I also like that an AT specifies what to do - but in the latest case - that didn't happen - until it was too late for me to realistically be able to deliver that. +09:31 < pinchartl> in my opinion, they only advantage in additional tasks, and the reason why they have been introduced, is to give a stick to Renesas to hit developers who don't deliver. with fixed deliverables and fixed due dates the work has to be completed, no excuse +09:31 < pinchartl> apart from that I see no use for additional tasks +09:32 -!- morimoto [~user@relprex2.renesas.com] has joined #periperi +09:32 < geertu> An AT deadline around the closing of a maintainer's merge window causes patches to be delayed by one kernel release. +09:32 < geertu> pinchartl: +1 +09:32 < wsa_> horms: if you could add what you currently know to the periupport list? so, we at least know which patches to "drop" +09:32 < dammsan> so we have been discussing dropping AT before +09:33 < dammsan> but at that point i requested some way to get plans from the group leaders +09:33 < horms> wsa_: sure, sorry for not having already done that +09:33 < pinchartl> dammsan: we can reduce paperwork and increase quality by dropping additional tasks completely and measuring performances to make sure we don't slow down (or even sleep) +09:33 < dammsan> this was last year i recall +09:33 < pinchartl> alternatively, we can keep fixed-price, fixed-term tasks, but with a higher latency. they *have* to be negotiated in advance +09:33 < dammsan> it is not a matter of increasing speed +09:34 < pinchartl> that is a contract has to be signed at least 2 months before the due date +09:34 < dammsan> it is a matter of improving visibility and communication +09:34 < jmondi> toothless jmondi's here +09:35 < dammsan> i will ask renesas if they can start considering 2 month delay +09:35 < dammsan> it is perfect for the last quarter of this year +09:35 < pinchartl> if the goal is to improve visibility and communication, then let's focus on that +09:35 < dammsan> until that time perhaps it is best that we drop additional tasks all together? =) +09:36 < dammsan> please note that some pipe lining is required +09:36 < pinchartl> dammsan: and I will also say that I agree we need to measure performances +09:36 < dammsan> one thing is the performance +09:36 < dammsan> another thing is to agree on what to do +09:37 < dammsan> i would like to have both +09:37 < kbingham> I'd like to not have high pressure workloads with short timescales :D +09:37 < dammsan> sure +09:37 < kbingham> I'd go join a tiger team if I wanted that ;D +09:38 < dammsan> but tell me how your 5 weeks can be split onto the existing slots +09:38 < neg> That is what I like about additional contracts, it provieds me with a clear channel from Renesas on what new task/feature is moste valuable for them and therefor I should focus on it. +09:38 < pinchartl> neg: I can only agree partially to that +09:39 < pinchartl> we are tasked with proposing additional tasks +09:39 < Marex> I have to admit, I like my kinda-free reign over U-Boot, since I can focus on doing what needs to be done when it needs to be done +09:39 < pinchartl> without being told what Renesas needs +09:39 < Marex> but maybe Im wrong :) +09:39 < pinchartl> so we try to guess +09:39 < kbingham> Marex, Do you not have additional tasks ? +09:39 < pinchartl> and then we are either told that the guess was right +09:39 < dammsan> he does but he prefers not to consume them +09:39 < pinchartl> or that it was wrong, in which case we are asked to guess again +09:39 < Marex> kbingham: I do, but I can live with that +09:40 < dammsan> what a nice fellow =) +09:40 < pinchartl> neg: I don't count that as being told by Renesas what is valuable for them :-) +09:40 < dammsan> pincharl: you seem to think the content of the bsp up porting list is enough +09:41 < neg> pinchartl: agreed, sometime the planing and late scheduling/decision point for a add. task is messy and creates higher workload. All I'm saying is that for me the task once scheduled provieds value +09:41 < pinchartl> Marex: I think most of us would like to focus on what needs to be done when it needs to be done, with additional inputs from Renesas when they have specific urgent needs +09:42 < dammsan> so may i ask if fixing the quarterly dates ahead of time has any drawback? +09:42 < kbingham> dammsan, What benefit are you addding with fixed dates... +09:42 < dammsan> i am not saying it solves all the problems +09:42 < pinchartl> dammsan: do you mean the Q2.1 and Q2.2 due dates, as in Q+1.5 and Q+2.5 ? +09:42 < kbingham> the 'due dates' are already predictable ... +09:42 < dammsan> this means we are clear about the dates +09:43 < dammsan> yes and meeting dates for chat meetings +09:43 < dammsan> if we agree on these ahead of time +09:43 < pinchartl> kbingham: the due dates are not just predictable, they are fixed :-) +09:43 < dammsan> and yet we fail to schedule tasks, then we won't schedule any tasks +09:43 < kbingham> :) +09:43 < pinchartl> dammsan: but we have already agreed, haven't we ? +09:44 < dammsan> i thought we had agreed to the AT due dates somehow +09:44 < dammsan> but yet it seems that the discussion of no time available and conference timing seems to happen again and again =) +09:44 < geertu> dammsan: Agreed as in: yes, let's use the dates Jinso needs the deliverables? +09:44 < dammsan> so if we know ahead of time.. +09:44 < pinchartl> dammsan: no, the problem isn't conference timing, the problem is late scheduling +09:45 < kbingham> If I'm going to 'lose' 3 weeks of work - then I need to know in advance - so I can find another three weeks of work to fill that time. Or Hugo losses his college fund! +09:45 < pinchartl> conferences and other events happen from time to time +09:45 < pinchartl> I can handle them by myself +09:45 < dammsan> kbingham: sure understood +09:45 < pinchartl> if you give me 3 weeks of work 6 weeks ahead of the due date +09:45 < pinchartl> I'll work around the conference that happens during those 6 weeks +09:45 < dammsan> makes sense +09:45 < pinchartl> if you give me 3 weeks of work 3 weeks ahead of the due date, that won't be possible +09:45 < geertu> pinchartl: Now, if you have 2x3 weeks of AT... +09:46 < pinchartl> and that's what is happening all the time +09:46 < pinchartl> in the best case we get the AT for 3 weeks of work 3 weeks ahead of the due date... +09:46 < dammsan> that seems to be because we don't do bre +09:46 < pinchartl> sometimes it's even later +09:46 < wsa_> kbingham: Hugo should be a rich kernel developer at college time, or? ;) +09:46 < dammsan> akout early enough +09:47 < kbingham> wsa_, I'm hoping he'll be a kernel developer at primary school :D +09:47 < pinchartl> dammsan: what do you mean by not breaking out early enough ? +09:47 < dammsan> well +09:47 < dammsan> for instance this virtualization topic +09:47 < dammsan> i wish we could meet and discuss how to proceed with that +09:47 < dammsan> now we have not met so much recently +09:47 < dammsan> and when we met in san sebastian the purpose seemed more to be for hacking than planning +09:48 < dammsan> i would like to meet with group leaders (+ others maybe) to do some planning +09:48 < pinchartl> I don't think we could have planned work for Q2 2018 in detail in San Sebastien +09:48 < pinchartl> there are various ways to meet, face to face or online +09:48 < kbingham> dammsan, I get that it was a communications issue - but in the Virt task - I was only told that *I* was supposed to write the task descriptoin - well after the point at which I would have expected to start the task - - hence for me - it's just impossible to fit in to a schedule in this current instance. +09:49 < dammsan> ok but i got the impression that you wanted to do the task? +09:49 < dammsan> i was pleasantly surprised that you signed up =) +09:49 < dammsan> obviously it was a too big jump +09:49 < pinchartl> dammsan: in general I think most of us are willing to help with work that is considered to be important by Renesas or you +09:49 < pinchartl> that shouldn't be a surprise :-) +09:49 < geertu> Exactly. +09:50 < dammsan> sure +09:50 < dammsan> i feel that +09:50 < dammsan> thanks for your help +09:50 < geertu> kbingham: You should have had some idea of what the task as about when volunteering, right? +09:50 < dammsan> but how to plan? +09:50 < dammsan> (and break out) +09:50 < kbingham> I knew very little about the task. +09:50 < dammsan> (that makes you the brave man in the room) =) +09:51 < kbingham> We are trying to hunt in the dark for tasks to fit into slots. +09:51 < kbingham> From my perspective - laurent said that dammsan wants us to look into virtualisatoin topics ... +09:51 < dammsan> sorry for being unclear +09:51 < kbingham> And thus I was expeting a virt topic to fill my available slots +09:51 < kbingham> However - I was expecting it to have been planned early - and be clear so that I could ramp up +09:52 < dammsan> but we had not done enough break out +09:52 < dammsan> also i feel we are moving slowly +09:52 < dammsan> probably due to lack of resources +09:52 < kbingham> I don't even mind if it would take me longer than the available time slots to do the investigation / self learning / and ramp up - but for that to happen - +09:52 < kbingham> the task *must start weeeeeellll in advance* +09:52 < dammsan> i would love to ask geertu to focus on virt activities +09:53 < dammsan> but without AT i feel i cannot request stuff +09:53 < kbingham> I see AT time slots as time slots that I reserve in my planning for to allow Renesas to fill with tasks. +09:53 < kbingham> But they can't be booked or not booked with zero notice. +09:53 < dammsan> kbingham: that view makes sense +09:54 < dammsan> but the default IMO is unbooked unless otherwise agreed +09:54 < horms> dammsan: when you say break out, do you mean you think it would help if there were more face-to-face meetings between say yourself and group leaders? +09:54 < dammsan> horms: yes +09:54 < dammsan> thank you +09:54 < horms> ok, I see a farily obvious way to see if that helps +09:54 < pinchartl> dammsan: unbooked unless otherwise agreed isn't something I can agree on as long as we book at the last minute +09:55 < pinchartl> if you want that, then I want to be booked 3 months in advance +09:55 < kbingham> So I should assume that 6/12 weeks of my time are not scheduled - and find another customer to fill that time ? +09:55 < pinchartl> as Kieran said in an e-mail, you don't expect to call a builder for your house and have him show up the next morning +09:55 < dammsan> sure, that fits perfectly fine with current budget situation =) +09:56 < kbingham> Ok - if we have budget restrictions - can we be clear about that!? +09:56 < pinchartl> there were no budget restrictions for Q2, were there ? +09:56 < dammsan> sorry if that has not communicated enough +09:56 < dammsan> but ATs are not guaranteed to be filled +09:56 < pinchartl> dammsan: it has been communicated badly, as in "beware of the big bad wolf" +09:57 < dammsan> never has been, and they are getting closer to be more sparse if budget is going bad +09:57 < kbingham> (beware, followed by - but don't go away) +09:57 < dammsan> well +09:57 < dammsan> it was actually my proposal to renesas side to tell you in advance +09:57 < dammsan> before you signed your base contracts +09:57 < dammsan> that budget is looking bad +09:57 < dammsan> so you should look into other options if you want to sustain +09:58 < neg> I think the budget situation have been communicated and also that there are possibilities that not all additional task slots will be used. Is this not why the base time was adjusted? +09:58 < dammsan> of course i want to work to with you +09:58 < dammsan> neg: yes +09:58 < dammsan> but i can't control our budget +09:58 < kbingham> Ok - but if AT's are not to be filled - they need to be filled with something else +09:58 < dammsan> especially if i can't make plans to show to renesas side +09:58 < kbingham> and tha'ts not possible - if the AT is filled at the last minute +09:59 < pinchartl> dammsan: why have additional tasks for Q2.2 not been scheduled in time, as there was no budget restriction for that period ? +09:59 < dammsan> kbingham: we seem to have different ideas how the contracts work +10:00 < kbingham> dammsan, I agree :) +10:00 < dammsan> what says that there was no budget restriction that period? +10:00 < dammsan> i was asked to reduce cost +10:00 < dammsan> i asked to reduce travel +10:00 < dammsan> did not to to EU +10:00 < dammsan> now if other members ask renesas directly +10:01 < dammsan> and they change their mind over a week +10:01 < dammsan> then it is not my problem +10:01 < kbingham> It's a shame you could not come to EU brussels - as it would have been good to do F2F then... :( +10:01 < dammsan> i agree +10:01 < pinchartl> dammsan: when we discussed additional tasks for Q2.2 there was no budget issue that was brought up, and tasks were agreed on to fill slots (but too late to be completed on time) +10:02 < dammsan> i have no intention to reduce the slots just for the sake of it +10:02 < dammsan> but we need to know what to do before doing it +10:02 < dammsan> and like my old fried paul said +10:02 < dammsan> you don't pay contractors to learn +10:02 < dammsan> you pay contractors to do what they are good at +10:03 < dammsan> of course some ramp up time is needed +10:03 < dammsan> and acceptable +10:03 < dammsan> but either you can do what you say +10:03 < dammsan> or you cant +10:03 < kbingham> dammsan, I actually agree on that - +10:03 < dammsan> and if we cant agree before the due date +10:03 < dammsan> too bad +10:03 < kbingham> That's why I expected the virt work to be planned well in advance :) +10:03 < dammsan> sure +10:04 < dammsan> so we had a some kerfuffle there +10:04 < dammsan> and in general when it comes to task break out and planning that may happen +10:04 < dammsan> probably my fault as usual +10:04 < dammsan> =( +10:04 < dammsan> but i stand by that we need to know before we do it +10:04 < pinchartl> it's not that it may happen, it happens all the time :-( that's for me a clear indication that the process is wrong +10:05 < dammsan> sure +10:05 < dammsan> but ive asked for plans forever +10:05 < dammsan> i would like to improve the situation +10:05 < pinchartl> I can't make a plan without being able to allocate resources +10:05 < dammsan> well +10:05 < pinchartl> I can't say what we'll do and when we'll do it if I'm not given a predictable amount of development time +10:05 < kbingham> I think we're well in to the territory of best discussed F2F :) +10:06 < kbingham> which is conveniently in 2 weeks or less. +10:06 < dammsan> i would like to separate assignment from planning +10:06 < dammsan> also time required from planning +10:06 < dammsan> only focus on break out and dependencies +10:06 < dammsan> i would like to discuss this with group leaders +10:06 < dammsan> ahead of time +10:07 < dammsan> then from the result of that activity feed AT and base work +10:07 < dammsan> if we manage to move forward with base only then we can skip AT +10:07 < dammsan> but dropping AT without any plans seems insane to me +10:08 < dammsan> kbingham: sorry that it became a mess +10:08 < pinchartl> so how do we move forward ? +10:08 < dammsan> how can we proceed? +10:09 < dammsan> i proposed my two ideas to improve the planning +10:09 < pinchartl> my requirement is that anything with a fixed due date has to be scheduled (as in contracts signed) at due date - max(2 * duration, duration + 2 weeks) +10:09 < dammsan> dates ahead of time + separate planning and breakout +10:09 < pinchartl> (the numbers can be fine-tuned +10:09 < dammsan> pinchartl: i want to agree as early as you +10:10 < dammsan> but we need to work together to break out stuff +10:10 < dammsan> and say that we are late +10:10 < dammsan> what happens then? +10:10 < dammsan> i don't want to be late +10:10 < dammsan> but if we end up there anyway? +10:10 < pinchartl> if you remember, I initially proposed a long list of tasks, and most got rejected with "this should be base time" or "this isn't a priority". I was then suppose to magically come up with new ides +10:11 < dammsan> also, crossi +10:11 < dammsan> ng quarterly boundaries is difficult +10:11 < dammsan> pinchartl: sorry if i made you feel rejected +10:11 < pinchartl> if we always end up being late we'll reach a point where stress and frustration will be so high that we'll lose developers completely. it won't just be a matter of some slots not being filled, people will go away +10:12 < dammsan> i understand. that's no good +10:12 < dammsan> but lets agree on a view with the contracts +10:12 < dammsan> no contract means no agreement +10:12 < dammsan> when it comes to assigned work +10:12 < pinchartl> if Renesas prefer stopping upstream development and only release BSPs, I won't stop them +10:13 < dammsan> well +10:13 < dammsan> if renesas can chose by themselves then we all have been reduced to up-porting machines +10:13 < dammsan> so no development on the horizon there no +10:13 < pinchartl> I'm sure they can find plenty of cheap developers who can write bad code +10:13 < dammsan> yep +10:13 < dammsan> we agree on that +10:13 < dammsan> so question is how to remedy that situation +10:14 < dammsan> without leaving people in a bad situation +10:14 < dammsan> also +10:14 < pinchartl> and if they prefer going that way, I have no issue making sure those bad patches won't make it to mainline +10:14 < dammsan> i don't want people to think they should be spoon fed with work +10:14 < dammsan> i want to share the burden of breaking out stuff with you +10:15 < dammsan> so we can collaborate to learn what next steps we need to take +10:15 * kbingham doesn't full understand what "breaking out stuff" means +10:15 < kbingham> Is that investigation and planning ? +10:15 < dammsan> kbingham: both perhaps +10:15 < pinchartl> by trying to move away from spoon-feeding and asking people to come up with task ideas for themselves, with such a fine-grained control, we have reached a situation that reminds me of kids in school who have to ask permission to go to the toilet +10:15 < dammsan> i asked for the dma virtualization topic +10:16 < dammsan> but in reality pinchartl found it to be 4 subtasks +10:16 < dammsan> unfortunately the ordering was odd +10:16 < pinchartl> dammsan: and it shouldn't have been my job to breakout a core task... +10:16 < dammsan> so we did the paper work before the so it happened after the contract was finalized =) +10:17 < dammsan> pinchartl: it seems that your role as coworked of kbingham might be conflicting with group leader +10:17 < dammsan> so i think we need to be more clear +10:18 < dammsan> kbingham: do you understand what i mean by breakout now? +10:18 < pinchartl> dammsan: I don't see a conflict. if you expect developers to work with group leaders to break out tasks I'm fine with that. what I disliked here is that Kieran and I were supposed to do the work all by ourselves +10:18 < kbingham> 'breakout = create additional task details' +10:18 < dammsan> kbingham: and split into subtasks +10:18 < kbingham> Yes - I was about to add that ;) +10:19 < dammsan> if we would have broken out ahead of time +10:19 < dammsan> then we could have assigned you something smaller instead +10:19 < dammsan> pinchartl: it was unclear about responsibility for sure +10:20 < dammsan> so how to proceed in the short term? +10:20 < dammsan> i proposed serial pass through only or also include clocks like you mentioned before +10:21 < pinchartl> today is June the 7th. the due date is the 15th. I'll let Kieran decide as this is his task, but personally I think it's too late to do anything +10:22 < dammsan> i have been told we may push back the due date until later this month +10:22 < dammsan> but you have your travels too +10:22 < kbingham> for available time remaining, I think perhaps dropping that to a 5 day task to cover the investigation already completed, and we can consider revisiting the task for next quarter. +10:23 < dammsan> kbingham: so serial pass through only? +10:23 < dammsan> which due date would you like? +10:23 < dammsan> is 15th ok or is later better? +10:23 < kbingham> I have got serial pass through working - so I don't mind the usual due date for that. +10:23 < dammsan> good! +10:24 < dammsan> can you email me your proposal how to change the text? +10:24 < kbingham> Sure I'll do that after the meeting. +10:24 < dammsan> perfect - thanks +10:24 < dammsan> i'll deal with this later today +10:25 < dammsan> so as final topic, how can we agree on the same view for the contracts +10:25 < dammsan> ? +10:25 < kbingham> dammsan, By sitting down with a beer. +10:25 < dammsan> alrighty =) +10:26 < dammsan> geertu: what do you think about agreeing on dates one quarter ahead of time? +10:26 < kbingham> :D +10:26 < geertu> dammsan: due dates and meeting dates? +10:26 < dammsan> wsa_: and what do you think about agreeing on dates one quarter ahead? +10:26 < dammsan> yeah +10:27 < geertu> What does that solve? We know the due dates, and can guess meeting dates (about every two weeks)? +10:27 < wsa_> for add. tasks? +10:27 < pinchartl> dammsan: haven't we agreed on due dates until the end of times already ? they're at Q+1.5 and Q+2.5. what else is there to agree on ? +10:27 < dammsan> chat meeting dates +10:27 < dammsan> so we know when we have to fix the AT titles + descriptions +10:27 < geertu> Do we have an issue with not knowing all future chat meeting dates? +10:28 < dammsan> we have an issue with AT creation which operates on chat meeting tick +10:28 < horms> dammsan: the chat meeting dates seem pretty predictable from my side +10:28 < horms> is the problem that sometimes we skip a week? +10:28 < pinchartl> dammsan: why don't we then decouple AT creation and chat meetings ? +10:28 < pinchartl> we can have ad-hoc meetings to create ATs +10:29 < dammsan> horms: sspinchartl: i agree if we can schedule break out meetings first =) +10:29 < dammsan> horms: no problem i think +10:29 < horms> sorry, the breakout term is very confusing to me +10:30 < horms> do you mean meetings to break out AT tasks? +10:30 < dammsan> tasks in general +10:30 < dammsan> that may or may not turn into AT +10:30 < horms> Ok, so task discussion meetings, separate from our regular meetings? +10:30 < geertu> Don't we usually handle AT titles over email? Decoupled from chat meeting? +10:30 < dammsan> if we have a bunch of tasks already broken out +10:30 < kbingham> https://paste.ubuntu.com/p/JcT9DrMQkT/ :D +10:31 < dammsan> then those should be easier to assign +10:31 < dammsan> horms: these discussions take time +10:31 < dammsan> and usually they get lower priority than actual hacking +10:32 < dammsan> and with travels and conferences and whatnot +10:32 < dammsan> it seems that we so far have not been able to come up with any plan (visible to me) +10:32 < pinchartl> dammsan: what kind of plan to you expect ? +10:32 < dammsan> a good example is the dma virtualization topic +10:33 < dammsan> you broke it out into 4 subtasks +10:33 < pinchartl> as I said, I can't create a plan with dates as I don't have development time I can assign to tasks +10:33 < dammsan> no need for dates +10:33 < dammsan> or time estimates +10:33 < dammsan> only titles and dependencies +10:33 < pinchartl> so if there's no date or time estimate, what kind of plan do you expect ? +10:33 < dammsan> maybe some details if possible +10:33 < pinchartl> a list of tasks ? +10:33 < dammsan> yes +10:33 < dammsan> with dependencies +10:33 < dammsan> for instance, clocks are missing from QEMU +10:33 < dammsan> so lets include a prototype task for that +10:34 < dammsan> before we do real development +10:34 < pinchartl> to find that out, nearly 5 days of work were needed. how could we have found out in a better way ? +10:34 < dammsan> we could have done it at aa different time IMO +10:34 < dammsan> maybe we should have aimed at serial pass through instead of going directly to DMA virt +10:35 < pinchartl> yes, but how ? what should have triggered that investigaion ? +10:35 < dammsan> serial pass through prototype? +10:35 < pinchartl> ok +10:35 < pinchartl> is it acceptable, when we schedule a prototype AT, to not deliver the expected prototype ? +10:35 < dammsan> or us sitting down and looking of +10:35 < dammsan> at what is needed? +10:35 < pinchartl> when features are missing for instance +10:35 < pinchartl> sitting down for 5 days ? :-) +10:35 < dammsan> we need deliverables +10:35 < pinchartl> it really required work +10:36 < dammsan> sure no doubt about that +10:36 < dammsan> (that's why i don't want to do it myself) =) +10:36 < dammsan> anyway +10:36 < dammsan> we can set aside base time +10:36 < pinchartl> in my opinion, there's no guarantee that a prototype can be delivered, ever +10:36 < dammsan> and meet and discuss these things over some time +10:36 < dammsan> then we are aiming too high +10:36 < pinchartl> by definition we create prototypes when the risk is high +10:37 < dammsan> so far all prototypes have been delivered =) +10:37 < pinchartl> and so we can run into blocking issues that can't be solved within the scheduled time frame +10:37 < dammsan> well, you take shortcuts +10:37 < pinchartl> so far we're had a combination of luck and dipping in base time. I don't think that's something we want to rely on as a rule +10:37 < dammsan> and if you cant then you have aimed too high +10:38 < dammsan> i'm open to suggestions though +10:38 < pinchartl> you can't know for sure how to aim, that's the whole point of prototypes +10:38 < dammsan> if you have any other ideas how to figure it out +10:38 < pinchartl> and taking shortcut can be acceptable to some extent +10:38 < pinchartl> but if we end up rushing to deliver something by taking too many shortcuts, then we delivere useless crap +10:38 < pinchartl> and waste time and money +10:38 < dammsan> there is a balance for sure +10:38 < pinchartl> in this specific case +10:39 < pinchartl> you could rush to create lots of hacks that will allow serial pass-through +10:39 < pinchartl> or start working on the missing features and not deliver the pass-through in time +10:39 < pinchartl> in the first came the patches will be garbage, nobody will ever use time +10:39 < kbingham> If a task 'suggestion' has begun - Investigtiaons and breakout - can simply occur in base time - in the quarter before>? +10:39 < dammsan> yeah? +10:39 < pinchartl> while in the second case the time is invested in a more productive and useful way +10:40 < dammsan> pinchartl: except the second does not consider the output of broken out tasks as useful +10:40 < pinchartl> dammsan: sorry, I didn't get that +10:40 < dammsan> kbingham: i agree +10:40 < dammsan> no sane person will take a prototype and put it into production +10:41 < kbingham> dammsan, Great - so we just need to get task suggestions started early. +10:41 < dammsan> but we can learn various things from it +10:41 < pinchartl> it's not about putting things into production +10:41 < dammsan> of course the ultimate goal is to solve the problem +10:41 < dammsan> but we need to learn what the problems are too +10:41 < dammsan> to know what we need to do +10:42 < dammsan> is it any more clear? +10:42 < pinchartl> if you spend 5 days learning about the issues and finding out what has to be solved, and have 5 days of budget left, consuming the remaining 5 days to write throw-away hacks just to tick the "done" box in the report is useless +10:42 < pinchartl> prototypes are valuable to find out about issues +10:43 < pinchartl> but once the issues are known it's pointless to create the dirtiest hacks just to check a box +10:43 < dammsan> if the prototypes happened by themselves then i would be the happiest man on the planet =) +10:43 < pinchartl> some hacks can be useful when they allow moving to the next step and finding about the next problem +10:43 < dammsan> the question is how the issues become known =) +10:43 < geertu> The hacks are useful to unblock you, and continue getting it to work, perhaps finding more issues to solve later. +10:44 < dammsan> geertu: yes +10:44 < pinchartl> or when they make a dependency for another task available faster than the proper solution +10:44 < geertu> Ineed, you won't know about the issues if you don't try. +10:44 < pinchartl> but if nothing else depends on your prototype, more hacks after all problems are known become throw-away code +10:44 < dammsan> i believe prototypes should be quick hacks +10:45 < dammsan> and i think my request to you was over reaching =) +10:45 < pinchartl> I think it's time to wrap this discussion up +10:45 < pinchartl> can we schedule a face to face discussion in Tokyo ? +10:45 < dammsan> sure, but how to make non-present members not feeling omitted? +10:46 < pinchartl> geertu: I think that question is for you +10:46 * geertu is wondering about this recent invention called "tubes", or "the Internet" +10:46 < dammsan> this travel planning is a cluster flower +10:47 < dammsan> geertu: i need to read the friendly manual =) +10:47 < pinchartl> dammsan: we have been told that there's no travel budget, and now we find out a face to face meeting is needed. there's an unavoidable conflict between those two :-) +10:47 < dammsan> i know - welcome to my life +10:47 < dammsan> i don't recommend it +10:48 < pinchartl> dammsan: I have never doubted that I'm not the only person to be frustrated by this :-) +10:48 < geertu> pinchartl: fall-out from the lack of travel budget around FOSDEM? +10:48 < pinchartl> so how can we schedule a meeting ? +10:48 < horms> dammsan: I recommend you have a f2f meeting.

Additional Multimedia Tasks for Q3 +10:39 < pinchartl> two additional tasks have been accepted for Q3 +10:39 < pinchartl> - R-Car Gen3 display output limitations +10:40 < pinchartl> - D3/E3 LVDS PLL support +10:40 < pinchartl> we now need to split them between all of us, and schedule them +10:41 < pinchartl> Renesas has requested us to reduce the budget +10:41 < pinchartl> by a 15, 20 or 25% amount depending on the phase of the moon +10:42 < pinchartl> the latest information I've been given is that we should prepare for a 15-20% reduction +10:42 < kbingham> I'm ok reducing some budget at the moment. +10:42 < uli___> is that a grand total, or for add. tasks only? +10:42 < dammsan> former +10:42 < pinchartl> grant total, but it seems OK to apply the reduction to additional tasks only +10:43 < pinchartl> that is, if you have 30 base + 30 additional, a 15% reduction is 9 days +10:43 < pinchartl> so you would end up with 30 base + 21 additional +10:43 < uli___> ok +10:44 < horms> I am happy to donate time other than that required for LTSI +10:44 < pinchartl> here are the current projections +10:44 < pinchartl> Member | Base + Add. | 15% | 20% | 25% +10:44 < pinchartl> -------------------------------------------------------------------- +10:44 < pinchartl> Jacopo | 33 + 15 | - 7.2 -> 5 | - 9.6 -> 10 | - 12 -> 10 +10:44 < pinchartl> Kieran | 20 + 25 | - 6.75 -> 5 | - 9 -> 10 | - 11.25 -> 10 +10:44 < pinchartl> Laurent | 35 + 25 | - 9 -> 10 | - 12 -> 10 | - 15 -> 15 +10:44 < pinchartl> Niklas | 20 + 10 | - 4.5 -> 5 | - 6 -> 5 | - 7.5 -> 10 +10:44 < pinchartl> Ulrich | 35 + 25 | - 9 -> 10 | - 12 -> 10 | - 15 -> 15 +10:45 < pinchartl> with the number of days rounded to the nearest multiple of 5 +10:45 < geertu> ;-) +10:46 < geertu> (about rounding) +10:46 < pinchartl> I know :-) +10:46 < pinchartl> if we prepare for 20%, we will be left with the following number of additional task days +10:46 < pinchartl> Jacopo: 5 +10:46 < pinchartl> Kieran: 15 +10:46 < pinchartl> Laurent: 15 +10:46 < pinchartl> Niklas: 5 +10:46 < pinchartl> Ulrich: 15 +10:47 < pinchartl> total: 55 +10:48 < pinchartl> who has or plan to have additional tasks scheduled for the core and I/O groups ? +10:48 < neg> My only plan is to have the 5 days I have for additional to happen in the second batch of Q3 if possible +10:49 < pinchartl> s/plan/plans/ +10:49 < pinchartl> I plan to ask for scheduling everything for the second batch (unless someone insists on having to deliver earlier) +10:49 < dammsan> seems good to me +10:50 < pinchartl> uli___: do you have additional tasks planned for Q3 for core ? I think I recall memory autodetection ? +10:50 < uli___> i intend to do that, but no talks about making that an add. task yet +10:51 < kbingham> pinchartl, for me, if there is not enough work to go around in MM, I could go back to looking at virt-topics with core ... but I'd want to make sure I've got a good understanding of the task requirements for that ;) +10:54 < pinchartl> sorry, I lost my internet connection +10:54 < pinchartl> kbingham: I think we'll have enough work on the multimedia side :-) +10:54 < pinchartl> uli___: geertu: how much time do you think will be needed by that ? +10:56 < uli___> 10 days, if i can get an atf upstreaming waiver (that's unknown territory for me) +10:56 < pinchartl> that would leave 5 days for multimedia then +10:57 < pinchartl> I should get an E3 board which has the sasme LVDS PLL +10:57 < pinchartl> so we could share the work between you and me +10:58 < uli___> do you have an idea how to split that? +10:58 < pinchartl> an easy way would be prototype + upstreaming +10:58 < pinchartl> 5 days fits a prototype better than an upstreaming task +10:58 < uli___> i would say +10:59 < pinchartl> do you think that makes sense, or would you prefer a different arrangement ? +10:59 < uli___> i think that could work +11:00 < pinchartl> would you be able to schedule that for mid-August ? otherwise I'd have trouble finishing it for mid-September, as my work would depend on yours +11:00 < uli___> would be ok +11:01 < pinchartl> thank you. I'll write task proposals then +11:01 < uli___> ok, thanks +11:01 < pinchartl> so that covers us +11:01 < pinchartl> for Jacopo, Kieran and Niklas, there are 25 days in total +11:02 < pinchartl> I think that can be covered by the "R-Car Gen3 display output limitations" task +11:02 < pinchartl> any opinion ? +11:03 < neg> I'm not sure what's included by the output limitation task +11:03 < kbingham> Are we thus going to just submit that as a task, and each work on it ? +11:04 < pinchartl> kbingham: more or less, but as we need to split the work anyway, I think we should include that information in the task description +11:04 < pinchartl> neg: +11:04 < pinchartl> - R-Car Gen3 display output limitations +11:04 < pinchartl> Display output on Gen3 platforms are subject to various resolution, pixel +11:04 < pinchartl> fomat and clock rate limitations depending on the SoC (or rather on the VSP, +11:04 < pinchartl> DU and internal encoders) and board. Few of these limitations are properly +11:04 < pinchartl> taken into account, which leads to random display output stability issues. For +11:04 < pinchartl> instance, 4k output isn't working properly, and parallel output (for VGA) +11:04 < pinchartl> pixel frequency limitations are not taken into account. +11:04 < pinchartl> I would like to propose an additional task to fix all this. The goal is to go +11:04 < pinchartl> through the documentation for each SoC and board we support, as well as +11:04 < pinchartl> through the contents of the BSP, to identify limitations for each platform and +11:04 < pinchartl> make sure they are all taken into account in the appropriate drivers. The work +11:04 < pinchartl> isn't extremely difficult, but in some cases we will need to implement +11:04 < pinchartl> currently unimplemented operations (in particular in the DU driver to take +11:04 < pinchartl> pixel rate limits into account), or possibly to even extend frameworks +11:04 < pinchartl> (although I don't think that should be needed, but I haven't double-checked). +11:06 < neg> pinchartl: thanks +11:06 < pinchartl> another option would be to find a 5 days additional task related to VIN for you, and have Jacopo and Kieran handle the display side. there's plenty of work in VIN, that's not an issue, but I don't know if that could be accepted as an additional task +11:06 < pinchartl> dammsan: any comment ? +11:06 < dammsan> fine with me +11:06 < neg> Only VIN task I see which is fit for add task is a UDS scaler prototype +11:07 < pinchartl> dammsan: which option is fine with you ? :-) everybody working on display, or proposing a VIN additional task ? +11:07 < pinchartl> neg: I'd like to move forward with the scaler too +11:07 < pinchartl> I think it's important to prototype that in the not too distant future +11:07 < dammsan> i'm ok either way, niklas working on vin makes sense to me +11:07 < pinchartl> in order to plan for proper upstreaming +11:07 < pinchartl> dammsan: thanks. it makes sense to me too +11:08 < pinchartl> so should we go for a VIN scaler prototype task ? +11:08 < neg> I would be fine working on the scaler +11:09 < pinchartl> I'll propose that then, thanks +11:09 < pinchartl> and split the DU work between Kieran and Jacopo +11:09 < neg> thank you +11:09 < pinchartl> (who can't disagree as he's not here :-)) +11:09 < kbingham> Well I'll handle the 4k work as I have already bought the 4K TV :) +11:10 < pinchartl> :-) +11:10 < pinchartl> we'll decide how to split the work when Jacopo will be available +11:10 < kbingham> What's the VGA issue? +11:11 < neg> kbingham: that's selfish, I thin Jacopo who do not yet own a 4k tv should handle that ;-) +11:11 < kbingham> (agreed, we can take further planning offline until Jacopo is here) +11:11 < pinchartl> various SoCs have different maximum pixel clock limits, this affects VGA and should be taken into account when reporting supported modes to userspace +11:11 < kbingham> neg, Well he could certainly test any patches if he needs a reason to expense a 4kTV :) +11:12 < neg> kbingham: :-) +11:12 < kbingham> pinchartl, Aha - ok I think I understand yes ;) +11:14 < pinchartl> so I think this covers additional tasks for Q3 +11:14 < pinchartl> any question or comment ? +11:14 < morimoto> quick question from me +11:14 < morimoto> wsa_: pinchartl: About tool, are you OK v2 style ? It is assuming you uses your own editor. I don't want to re-work script many times. It still doesn't have bsp upport and report features +11:14 < pinchartl> morimoto: is that an additional task ? :-) +11:14 < morimoto> but you can see its behavior +11:14 < morimoto> hehe :) +11:14 < morimoto> Just question +11:15 < pinchartl> I'll reply to your e-mails today or tomorrow. I'm sorry for the delay, I've been traveling a lot after our meeting in Tokyo +11:15 < morimoto> OK +11:15 < morimoto> but, your "I will do it in next week" never worked for me :) +11:15 < morimoto> +1. do you think it will be useful if new tool can handle base/additional task days ? +11:15 < wsa_> morimoto: I wanted to have a look later today +11:15 < pinchartl> I know, that's why I said today or tomorrow, not next week :-) +11:15 < morimoto> wsa_: thanks +11:15 < pinchartl> I haven't had time to read the latest mails in the thread yet +11:15 < morimoto> pinchartl: OK, thanks +11:16 < morimoto> OK, no problem. +11:16 < morimoto> I'm looking forward to see you respoce +11:16 < morimoto> thanks, thats all from me +11:16 < pinchartl> thank you +11:16 < pinchartl> this leads us to +11:16 < pinchartl> Topic 3.

There's +11:18 < pinchartl> plenty of work there. +11:18 < pinchartl> - The kingfisher boards has GMSL and TI concurrent solution for remote +11:18 < pinchartl> camera/displays. Having one would be sweet but it is hardly available and +11:18 < pinchartl> expensive. +11:18 < pinchartl> - Driver sent upstream but not yet received feedback +11:19 < pinchartl> - From the periperi upport list +11:19 < pinchartl> (All commit reference from https://git.kernel.org/pub/scm/linux/kernel/git/horms/renesas-bsp.git/) +11:19 < pinchartl> - EBISU needs VIN and display output support +11:19 < pinchartl> commit/?id=5ee0043347b63d40cf088740fb07285d4178f82c +11:19 < pinchartl> commit/?id=51b12d070f3ddc9bbf7232028e5d1571c95eb473 +11:19 < pinchartl> - M3-W ULCB fixes: Z clock support, CPU idle +11:19 < pinchartl> commit/?id=9c21d6d3ebacf11cb241e086902a2ecfe6e779d6 +11:19 < pinchartl> commit/?id=22fa2b4b9dd0f78e02f8d890a9cf98fda8757ad4 +11:19 < pinchartl> commit/?id=fe16e454b991dbd280a95ebe48aa595915d4610b +11:19 < pinchartl> - There is an LVDS panel driver, which I'm not sure in which board/expansion +11:19 < pinchartl> is.

The board is expensive (1000€) so buying it is not an option. The patches can still be upstreamed if Chris and Fabrizio can test the rebased version. +11:19 < pinchartl> - MT9T112: this chip is integrated in some old SH boards with CEU. Jacopo has a camera module that can be connected to a Peach to board test the driver. He hasn't been able to capture any image yet. +11:19 < pinchartl> - RZ/N pincontrol has been sent upstream and then abandoned. Is there interest in those chips ? +11:19 < pinchartl> I'm not sure why Z clock support and CPU idle is there, it's not multimedia +11:20 < pinchartl> so I'll remove that +11:20 < kbingham> I would like to start some pressure on the fault redundant V4L2 topic, so if it's ok - I'll try to formulate a RFC patch / and or email thread to bring the topic up with Hans as base work. +11:20 < pinchartl> I think that make sense +11:21 < pinchartl> CEU is more or less unfunded +11:21 < pinchartl> Jacopo seems to like it though +11:21 < pinchartl> so if he can find a bit of time to spend on it, I have no issue +11:21 < pinchartl> but I'd like to concentrate on two topics for the base time +11:21 < pinchartl> - backlog reduction +11:21 < pinchartl> this includes both our own backlog and the BSP patches +11:21 < pinchartl> - GMSL +11:22 < pinchartl> fault-tolerant V4L2 is part of that +11:22 < pinchartl> any comment ? +11:22 < geertu> FWIW, Armadillo also has an MT9T112. So if it works on Peach, I can test CEU on Armadillo. +11:22 < geertu> s/CEU/the new CEU/ +11:22 < neg> I think the two focus areas for base are good +11:23 < kbingham> Yes, I think having directed focus is definitely a postive +11:23 < pinchartl> geertu: thanks for the offer +11:23 < neg> kbingham: as a first step now that parallel input support is in media-tree would be to move the vl42 video device registration to VIN probe(), I'm sure Hans will react to that :-) +11:24 < kbingham> neg, I think getting an initial reaction is a good starting point for the dicussion :) +11:28 < pinchartl> regarding backlog reduction and GMSL, I propose to discuss tasks over e-mail as this meeting is already running late. I'll initiate the discussion +11:28 < pinchartl> is that ok ? +11:28 < kbingham> Yes. +11:28 < neg> ok for me +11:28 < pinchartl> thanks +11:29 < pinchartl> next topic +11:29 < pinchartl> Topic 4. Periperi Annual Meeting +11:30 < pinchartl> lots of locations have been proposed since our last meeting in San Sebastian +11:30 < pinchartl> it's now time to decide +11:30 < pinchartl> Wolfram has proposed meeting in Paris right before or after Kernel Recipes +11:31 < pinchartl> while a week under the sun in southern Europe would have been more tempting for me, I think his proposal makes +11:31 < pinchartl> sense +11:31 < pinchartl> Paris isn't as horrible as the Belgian countryside :-) +11:31 < pinchartl> Magnus already mentioned he won't be able to attend due to a personal additional task +11:32 < pinchartl> the real question, of course, is whether we'll have budget to organize this +11:32 < pinchartl> while it hasn't been confirmed, I have repeatedly been told that we should move forward with planning +11:32 < pinchartl> dammsan: is my understanding correct ? +11:32 < dammsan> i think so +11:33 < pinchartl> thank you +11:33 < pinchartl> what's everybody's opinion about the proposed location and time ? +11:34 < pinchartl> KR is Sep 26-28 +11:34 < dammsan> it is about time for me to wrap up, may i be excused? +11:34 < Marex> pinchartl: I'll be speaking at ER, vaishali at KR I think +11:34 < Marex> pinchartl: how does one register to KR , are the tickets available already ? +11:34 < Marex> pinchartl: it'd suck to have to wait it out +11:34 < kbingham> Marex, no I don't think tickets are available yet. +11:35 < kbingham> But they go pretty fast - so it's best to register on the day they come out;. +11:35 < Marex> kbingham: which is ... when ? :) +11:35 < Marex> kbingham: happened to me last time, yeah +11:35 < kbingham> Marex, Exactly. +11:35 < kbingham> When :) +11:36 < kbingham> The time I went - the release date was announced on twitter. +11:36 < pinchartl> there's usually about 100 seats available +11:36 < Marex> bleh +11:36 < pinchartl> I'm not sure it would be fair taking 10% of that for our team... +11:37 < pinchartl> I mean, if people want to attend, sure, but I don't think we should push everybody to attend just because we would meet before or after the conference +11:37 < Marex> pinchartl: except I think many people do want to attend anyway +11:37 < wsa_> I am only available before KR +11:38 < pinchartl> Marex: has the schedule been decided already, or is it still worth proposing a talk ?

+11:40 < kbingham> Yes here. +11:40 < pinchartl> Marex: just for my information, when did you submit your talk proposal ? +11:40 < geertu> I think it's doable +11:40 < pinchartl> wsa_: how about you ? +11:41 < wsa_> that week works for me +11:41 < wsa_> we have a meeting scheduled on 20th anyhow ;) +11:41 < pinchartl> :-) +11:41 < neg> 17-21 looks OK in my calendar +11:41 < uli___> good for me, too +11:43 < Marex> pinchartl: they polled me for a talk in Feb or so +11:43 < Marex> pinchartl: then I heard nothing for a long time, then they asked me for abstract a few days ago +11:43 < Marex> 17-21 is I think OK for me +11:43 < pinchartl> Marex: thanks +11:43 < pinchartl> ok, please block those dates +11:43 < pinchartl> and submit a travel plan to secure budget +11:44 < pinchartl> with cost estimates for travel and accommodation +11:44 < uli___> to whom? +11:44 < wsa_> I assume we are going for the huge appartment thing again? +11:44 < Marex> in Paris ? :) +11:44 < Marex> I thought there were only small romantic apartments there +11:44 < pinchartl> dammsan: as Morimoto-san isn't here, should he volunteer to handle this ? :-) +11:45 < pinchartl> I think we can send him the travel plans +11:45 < pinchartl> wsa_: I think it would make sense, both from a cost point of view and from a meeting infrastructure point of view +11:45 < wsa_> Marex: if that's the case, I might have no time to work +11:45 < wsa_> ;) +11:45 < pinchartl> we will need two or three apartments I assume +11:45 < Marex> pinchartl: +1 +11:46 < dammsan> good idea +11:46 < dammsan> =) +11:47 * vaishali wonders what happens in periperi annual meeting and if she is supposed to attend it. +11:47 < geertu> wsa_: How many small romantic apartments do you need? ;-) +11:47 < pinchartl> 3 apartments = one per group leader ? +11:49 < geertu> 162€ for the train to/from Paris +11:49 < pinchartl> dammsan: could you be so kind to explain to vaishali what the annual meetings are ? +11:49 < wsa_> geertu: depends a bit on how widespread polyamory is in Paris :) +11:49 < neg> 3 group leaders, 3 apartments ... is this one of these TV realtiy shows where we compete and vote ppl to exile? +11:50 < dammsan> i think neg summed it up pretty well =) +11:50 < kbingham> Lol :) +11:50 < geertu> vaishali: Pinchartl may ask you to bring a spoon... +11:51 < marex-cloud> geertu: whatever happens in periperi annual meeting, stays in the meeting ... it's like Vegas ;-) +11:51 < geertu> marex-cloud: Can you get married with Elvis? +11:51 < pinchartl> vaishali: in a nutshell, we spend a week together to discuss yearly planning +11:51 < marex-cloud> geertu: sssssssssssh +11:51 < wsa_> We have something like a mixture of a co-working space and a hotel near where I live. Maybe something like this exists in Paris as well? I'll check +11:51 < pinchartl> and possibly organize code camps on the side if time permits +11:53 < neg> I think more code camp time is a good idea, the FOSDEM one was productive IMHO +11:54 < pinchartl> neg: I agree with you +11:54 < vaishali> pinchartl: Ok, code camps sounds like fun. As I'm coming for KR anyway, I think I can come a week early. +11:54 < pinchartl> vaishali: perfect :-) +11:54 < pinchartl> let's try to close the meeting, it's getting late +11:54 < pinchartl> Topic 5.

Status updates +09:33 < geertu> A) What have we done since last time: +09:33 < geertu> Marek studied PCIe errate. +09:33 < geertu> Morimoto-san worked on PeriJect. +09:33 < geertu> Niklas provided a fix for the V3M PFC crash for the stable tree. +09:33 < geertu> Shimoda-san investigated and fixed rcar-dmac issues, submmited an R-Car +09:33 < geertu> E3 USB3 host DTS node patch, and asked the HW team about V3H EXTAL +09:33 < geertu> value. +09:33 < geertu> Geert implemented rcar-gpio get_direction(), added author signoff +09:33 < geertu> checking to checkpatch, got bd9571mwv toggle power switch support +09:33 < geertu> accepted, made SATA device-passthrough for virtualization work, and +09:33 < geertu> reworked the R-Car gen3 OSC and RCLK improvements. +09:34 < geertu> B) What we plan to do till next time: +09:34 < geertu> Marek will work on U-Boot (SPL-alike replacement for Minimon) and +09:34 < geertu> OpenOCD for Gen3. +09:34 < geertu> Morimoto-san will add HTML support to PeriJect. +09:34 < geertu> Shimoda-san will pave the way forward for IPMMU. +09:34 < geertu> Geert plans to submit v2 of the R-Car gen3 OSC and RCLK improvements, +09:34 < geertu> work on LTSI sub-maintainership, and look into GPIO paravirtualization, +09:34 < geertu> and SYSC and PFC errata. +09:35 < geertu> C) Problems we have currently: +09:35 < geertu> Marek is suffering from the European heat wave. +09:35 < geertu> Morimoto-san wonders if PeriJect is good enough to use, and how to +09:35 < geertu> migrate from periupport and peripelist. +09:35 < geertu> Ulrich has been suffering flaky Internet for weeks. +09:35 < geertu> Anything I missed? +09:35 < geertu> Ah, Simon just sent his report +09:36 < geertu> Kaneko-san posted M3-N CPUFreq upport, and will test it. +09:37 < horms> On the Kaneko-san front. Main task is to get him hooked up to Magnus's lab. Second task is to address missing patches he reported in his backports. I'm assuming these tasks fall to me. +09:37 < horms> Missing patches are only in backports he hasn't posted :) +09:38 < horms> Sorry once again for the late report. +09:39 < geertu> horms: Havw you tried contacting Olof privately? +09:40 < horms> I am considering it after the most recent wave of feedback. +09:40 < horms> I think he is conciously or otherwise trying to tweak the realationship between himself and us (and possibly other downstreams too) +09:40 < horms> It might help to understand why that is happening. +09:41 < horms> e.g. he is unhappy about something; Linus is unhappy about something; he has assumed more control over ARM SoC, ... +09:42 < horms> Feedback from the team is of coruse welcome as I see my role mainly as an intermedeary +09:42 < wsa_> TBH I didn't notice much of that, except his wish to aquash patches more +09:42 < geertu> Most other pull requests seem to be answered with "Merged, thanks" +09:42 < wsa_> squash +09:43 < wsa_> and i do understand that +09:43 < horms> So the thing is. I don't mind if we tweak our processes and that works better for everyone. +09:43 < Marex> horms: you think Linus is pushing on Ojn ? +09:43 < horms> Squashing may be in that category, but its a bit too early to say +09:44 < Marex> horms: ah, forget what I said ... +09:44 < horms> But I don't want Renesas to become some sort of punching bag +09:44 < horms> Marex: I think is possible +09:44 < horms> Its also possible that I am blowing things out of proportions +09:44 < wsa_> horms: i surely agree on not being a punching bag :) +09:44 < Marex> horms: please ask him what's this about, being forced to drop patches is really sad +09:45 < horms> And his requests can be distilled into 3 categories each of which are reasonable(ish) +09:45 < horms> 1) sqaush 2) shorter changelogs (Arnd liked longer ones) 3) specific opinions on some specific patches +09:45 < wsa_> does renesas add more SoCs than other vendors these days? +09:46 < horms> But perhaps there is little harm in simply asking him privately +09:46 < horms> wsa_: maybe. It certainly has a lot upstream +09:46 < kbingham> horms, Is olof changing your tags, and thus breaking your signatures? (/me grabs popcorn to read Olof's replies) +09:46 < wsa_> yes +09:47 < geertu> Renesas is pumping out SoCs at 2 SoCs/kernel release these days +09:47 < geertu> Anyway, let's continue +09:47 < geertu> Topic 2. Discussion Topics +09:47 < geertu> RZ/G2 compatible values +09:47 * wsa_ still recalls Arnd at last ELCE mentioning Renesas at second place when asked about vendors having good upstream support +09:48 < geertu> Chris Patterson just asked about this, and he would like to join our discussion. Is that OK? +09:48 < pinchartl> wsa_: who was first ? +09:48 < wsa_> with Atmel being 1st, but all agreed they have more simple chips in the first place :) +09:49 < wsa_> I think GPUs were excluded in that discussion :/ +09:49 -!- patersonc [c18ddb24@gateway/web/freenode/ip.193.141.219.36] has joined #periperi +09:49 < patersonc> Mornin +09:49 < geertu> Welcome chris +09:49 < wsa_> Hi Chris! +09:50 < kbingham> Hola :) +09:50 < Marex> Hey +09:50 < geertu> Some of you may have met Chris. He's working on RZ/G. +09:50 < horms> Hi Chris +09:50 < uli___> hi +09:50 < geertu> So the first SoC they're upstreaming support for is RZ/G2M aka R8A774A1 +09:50 < neg> patersonc: hi :-) +09:51 < geertu> using compatible value "renesas,r8a774a1" +09:51 < geertu> But more are to follow, cfr. the email I sent to the mailing list. +09:52 < patersonc> Fun times +09:52 < geertu> Recently, we started using 5 digits in compatible values, even if the last one is a zero (e.g. r8a77970) +09:53 < geertu> However, there will also be an RZ/G2M variant R8A774A0 +09:53 * jmondi would bribe patersonc to get an iWave board :p +09:53 < geertu> AFAIC it would be identical, except for the lack of HDMI +09:54 < geertu> Of course I'd like to avoid having both "renesas,r8a774a1" and ""renesas,r8a774a0" compatible values. +09:54 < patersonc> jmondi: depends on what you want to do with it ;) +09:55 < geertu> We could settle on "renesas,r8a774a", but then there's the risk there will be a comnpletely differeny R8A774A5 later (cfr. M3-W and M3-N) +09:55 < geertu> s/comnpletely differeny/completely different/ +09:56 < horms> I think that this is not very different to the problem we have faced in the past +09:56 < geertu> Does anyone have an opinion about this? +09:56 < wsa_> I gotta run +09:56 < horms> And the solution has essetntially been that new compat values are cheap +09:56 < wsa_> cya guys +09:56 < geertu> wsa_: Bye! +09:57 -!- wsa_ [~wsa@p5099505f.dip0.t-ipconnect.de] has quit [Quit: ...] +09:57 < horms> And the cost of finding ourselves painted into a corner would be unbearable +09:57 < geertu> "cheap" as in lot's of DT binding doc updates? +09:57 < kbingham> is it bad to have "renesas,r8a774a" and "renesas,r8a774a5" ? +09:57 < horms> Yes, that has essetntially been the possition for some time now +09:57 < geertu> patersonc: R8A774A1 and R8A774A0 would really be the same die? +09:58 < patersonc> I would assume so. Just the HDMI IP disabled +09:58 < patersonc> For licencing reasons +09:58 < horms> Ok, so we could have an extra .dsti file that did disabled/removed that node? +09:58 < geertu> Then using "renesas,r8a774a1" for R8A774A0, too, would be acceptable, as it conforms to the original meaning of compatible values +09:59 < geertu> horms: The HDMI node would not be instantiated unless someone changes its status to "okay" in the board DTS +10:00 < horms> ack +10:00 < horms> Perhaps that is an easy way out in this case +10:00 < pinchartl> patersonc: does "HDMI IP disabled" really mean disabled ? or will it work if someone tries to use it ? +10:00 < patersonc> Would we use both r8a774a* compatible strings in r8a774a1.dtsi? +10:00 < geertu> It would only be an issue if someone plugs an A0 SoC into a board designed for an A1 (assumed they'll be pin compatible) +10:00 < horms> kbingham: I think that is not bad but at the same time it would be confusing -> not particularly good +10:01 < patersonc> pinchartl: I would hope they would blow an efuse for HDMI, so it won't be usable +10:01 < kbingham> horms, Ack. +10:01 < geertu> patersonc: No, just "renesas,r8a774a1" (and "renesas,*rcar-gen3*" as fallback for individual IP cores where appropriate, cfr. RZ/G1) +10:01 < patersonc> Okay +10:02 < horms> geertu: I think that is fine if we are satisfied that these two SoCs really are compatibile. That seems to be the case from what Chris is saying +10:02 < geertu> horms: Agreed +10:02 < patersonc> That's the information I have! +10:02 < horms> A lot of this thining regarding compat values goes back to a time when we could not tell if hw A was really compatibile with B or not +10:03 < horms> geertu: ok, so assuming that is settled. are there other related compat valeues to discuss +10:03 < pinchartl> horms: I agree with you +10:03 < patersonc> Given that they aren't creating a new device anyway (using R-Car), I doubt they are going to create a new device just to remove the HDMI IF ;) +10:04 < geertu> patersonc: Will they blow eFuses for the other "removed" devices? +10:04 < patersonc> geertu that would be my assumption +10:04 < geertu> Did they actually do that on RZ/G1? +10:04 < patersonc> As far as I understand it, yet +10:04 < patersonc> yes * +10:04 < geertu> OK. +10:04 < patersonc> The whole point was to save on costs +10:05 < geertu> So let's go for "renesas,r8a774a1". +10:05 < geertu> patersonc: Thanks for joining, Chris! +10:05 < patersonc> Thank you all! +10:05 < horms> This sounds like a good option: It leaves us room to move in future. And solves the curent problem. +10:06 < patersonc> You can ack Biju's patches now ;) +10:06 < geertu> patersonc: Sure. Will do. +10:06 < horms> Are you sure you don't also want to document "renesas,r8a774a2"? +10:06 < patersonc> horms you mean a0? +10:06 < horms> I guess there is no point unless its also used in a .dtsi +10:06 < horms> yes, sorry, my bad +10:07 < horms> and we seem to now want an extra .dtsi at this point +10:07 < geertu> Perhaps at the highest SoC level (DT root node)? +10:07 < horms> I'm just thinking in terms of freedom to move if we need to +10:07 < horms> But perhaps I need to just accept that the hw is the same +10:07 < patersonc> We could document a0 (and all the others), but I'm not sure I'll ever actually get hold of an a0 device. They will just go straight to customers. Only a1 will be used on the reference hardware. +10:07 < geertu> We don't have r8a77951 for H3 ES2+ neither +10:08 < horms> True. I was pondering the similarities between this problem and R-Car Gen 3 ES versions. +10:08 < patersonc> At least with RZ/G we shouldn't have lots of ES versions +10:08 < patersonc> (famous last words) +10:09 < horms> Ok, so we think the hw is compatible +10:09 < horms> with good reason. +10:09 < horms> It might change, f.e. with a new ES versinos +10:09 < horms> But we don't have a good way to deal with that +10:09 < horms> And as a bonus we think its unlikely +10:10 < horms> So the simple solution of just documenting and using "renesas,r8a774a1" seems sufficiently safe +10:10 < horms> Is that about where we are? +10:10 < geertu> In hindsight, probably we should have made H3 ES1.0 a different SoC, and thus used r8a77951 for H3 ES2+ +10:10 < patersonc> Sounds good to me horms +10:11 < geertu> Agreed +10:11 < horms> geertu: true. I guess my only question is if we should learn from that mistake at this time +10:11 < geertu> horms: Well, most ES increments are small fixed +10:12 < patersonc> I'm sorry but I have to go to the doctors. I'll be back in a couple of hours. Thank you all for your time! +10:12 < geertu> patersonc: Thx, CU, and take care! +10:12 < geertu> Any other topic to discuss for the regular core meeting? +10:14 < horms> I also need to leave soon as someone is coming to inspect my current home +10:14 < horms> patersonc, all: thanks for the good conversation on this topic +10:14 < geertu> So I think we're done. +10:14 < geertu> Thanks for joining, and have a nice continued day! diff --git a/wiki/Chat_log/20180726-io-chatlog b/wiki/Chat_log/20180726-io-chatlog new file mode 100644 index 0000000..7b6ac76 --- /dev/null +++ b/wiki/Chat_log/20180726-io-chatlog @@ -0,0 +1,65 @@ +09:03 < wsa_> Welcome to the IO meeting! +09:04 < wsa_> As mentioned in my mail, I couldn't prepare a summary this time, so I will start with questions I have about the reports you sent +09:04 < wsa_> and/or about upport status +09:04 < wsa_> geertu: I noticed some suspend/resume patches in periupport which have no further comments +09:04 < wsa_> for msiof +09:05 < wsa_> do you know about them? +09:05 -!- morimoto [~user@relprex2.renesas.com] has joined #periperi +09:05 < morimoto> Hi +09:05 < wsa_> other than that, thanks for the suggestions about SATA, I think we are on a good path there +09:05 -!- ulih [~Mutter@x2f7feb1.dyn.telefonica.de] has quit Quit: Mutter: www.mutterirc.com +09:06 < wsa_> hi morimoto-san +09:06 < geertu> wsa_: I'll have a look again +09:06 < wsa_> thanks! +09:07 < wsa_> neg: about using !4tap in your newest patch series.

I think it is an elegant solution :) +09:13 < Marex> wsa_: I think the whole HS400 switch is real simple, which is what the SDHI tries to explain in a tad clumsy way +09:14 < wsa_> And it gets rid of the "implement I2C_M_STOP" task for i2c-rcar... +09:14 < Marex> wsa_: you don't need to calibrate again for the HS400 +09:14 < pinchartl> wsa_: I've always thought that regmap had a bit too large overhead for my tastes, but apart from that, yes, it's all fine +09:14 < Marex> wsa_: that's why you don't need to read the SCC register I think +09:15 < pinchartl> but I2C_M_STOP should still be implemented, don't you think ? :-) +09:15 < wsa_> Marex: but 8 tap vs 4 tap has nothing to do with HS400.

+10:39 < pinchartl> in my opinion, we're really moving in the right direction +10:39 < pinchartl> and I think we should be able to start using it soon +10:39 < morimoto> kbingham: I agree. maybe we are misunderstanding each +10:40 < pinchartl> thanks for pushing it to a git repo, that will help tracking changes +10:40 < morimoto> np +10:40 < kbingham> (in regards to the peri-schedule, I saw it as a specialised tool that would turn human readable text into a google calendar feed, and didn't necesarily expect that to be part of periject) +10:40 < pinchartl> regarding one tool for multiple purposes, I'm fine with that when the purposes are related +10:40 < kbingham> That code 'could' live in periject too. +10:41 < morimoto> kbingham: about google calendar, can you share it to us ? +10:41 < kbingham> morimoto, I have :) +10:41 < morimoto> I think google calendar is such feature +10:41 < morimoto> nice +10:41 < kbingham> morimoto, https://periperi.gitlab.io/peri-schedule/periperi.ics +10:42 < kbingham> It's generated by code which is currently hosted privatly on gitlab, (because it contains our group confidential information about our meetings, so I didn't want that to be unnecessarily public) +10:42 < morimoto> no, I think you can select me on google calendar +10:42 < pinchartl> regarding periject, I'd like to concentrate on tasks and BSP commits (bug reports) first as that's the main target +10:42 < kbingham> The ICS file can be added as a calendar feed in google-calendar or any other calendar tool +10:42 < pinchartl> once done with that, let's see what else would make sense to integrate in the tool +10:43 < kbingham> (sorry - not file - URL ... you add the URL - and google reads it when it's updated) +10:43 < kbingham> you don't need to download the file, and then uplaod or anything like that - it's a one add job :) +10:44 < kbingham> To do the same from periject would require a public url space ... that's all. +10:44 < pinchartl> something that I think would be useful is to start populating the repository with a set of real tasks (let's say about 10) +10:44 < pinchartl> in order to better understand how it works +10:44 < kbingham> ^ I agree :) +10:45 < kbingham> Is it one file per task ? +10:45 < morimoto> kbingham: you can select +10:45 < pinchartl> I don't like having multiple options +10:45 < morimoto> 1 file / 1 task or 1 file / multi tasks +10:45 < pinchartl> as in one task per file, or multiple tasks per filie +10:46 < pinchartl> or with or without white spaces to indent lines within a file +10:46 < pinchartl> we should document the file format clearly +10:46 < pinchartl> and stick to one format +10:46 < pinchartl> otherwise it will become messy with everybody having a slightly different style +10:46 < kbingham> peri-lint.py ;) +10:47 < pinchartl> kbingham: we need a git commit hook that will validate the format +10:47 < kbingham> pinchartl, morimoto-san already has a git hook in place to do sanity checks +10:47 < kbingham> So I'm sure that can be extended as necessary +10:48 < kbingham> And actually - I like that the code lives in the same repository as the data in this instance - because it will enforce everyone being on the latest version of the code - if they have the latest version of the data ;) +10:48 < pinchartl> I think we should continue this discussion over e-mail to ensure we keep track of it +10:48 < kbingham> (normally I would have separated) +10:48 < morimoto> about alignment, creating "tool rule" is OK for me. But 1 task / 1 file vs multi task / 1 file is "operation rule" for me +10:48 < pinchartl> kbingham: I have mixed feelings about that +10:48 < pinchartl> it makes the history pretty messy +10:49 < morimoto> I want to have flexibility +10:49 < pinchartl> morimoto: why is it an "operation rule" ? (and what do you mean by that exactly ?) +10:51 < morimoto> I understand "you" don't like it. But "otherone" might like it. I don't want to force to 1 opinion +10:51 < morimoto> If you don't like it, you just don't do it. +10:52 < pinchartl> it then becomes a real mess +10:52 < morimoto> This is my "operation rule". If tool forced it it is "tool rule" +10:52 < pinchartl> what if I'd prefer a third format and implement support for it ? will it be accepted as I won't force anyone to use it ? +10:52 < pinchartl> or a fourth, fifth format ? +10:52 < pinchartl> also, it's not true that nobody would be forced to do it +10:52 < pinchartl> as we'll all have to modify tasks not created by us +10:52 < pinchartl> or at least read them +10:53 < pinchartl> readability is very important, and comes from consistency +10:53 < pinchartl> same as for coding style, if we had no coding style rule in the linux kernel, it would be awful +10:53 < morimoto> Having coding rule is OK for me. +10:54 < morimoto> About task vs file, let's use 1st. I think you are misunderstanding +10:54 < morimoto> or I'm misunderstanding +10:55 < pinchartl> the reason why I think we should have a single task per file is that looking at the contents of the tasks directory should give us an overview of all tasks, with file names containing the task subjects +10:55 < pinchartl> you can't do that with multiple tasks per fil +10:55 < pinchartl> e +10:56 < pinchartl> but again, I think we should continue this discussion over e-mail, it's getting out of scope for multimedia +10:56 < morimoto> agree +10:57 < pinchartl> thank you +10:57 < pinchartl> Topic 2. Additional Multimedia Tasks for Q3 +10:57 < pinchartl> we have agreed on additional tasks last time, I'll submit task descriptions to Magnus before the end of the week +10:57 < neg> thanks for doing that +10:57 < pinchartl> kbingham: jmondi: have you sorted out how to split the work between the two of you ? +10:57 < pinchartl> neg: you're welcome +10:58 < jmondi> pinchartl: so far we've been working in going through the BSP patches realted to du/drm together +10:59 < pinchartl> do you need any help ? +10:59 < jmondi> so short answer is "not yet" +10:59 < kbingham> pinchartl, not a direct split, because we don't have a clear boundary +10:59 < pinchartl> ok :-) +10:59 < jmondi> Help yes, but I think going through email is easier +11:00 < pinchartl> fine with me +11:00 < pinchartl> Topic 3. Periperi Meetings +11:00 < pinchartl> The plan for an annual meeting in Paris around Kernel Recipes has been canceled, and the meeting will take place in Edinburgh around ELCE. +11:00 < pinchartl> I would still like to organize a multimedia code camp in September, the two candidate locations being Paris around Kernel Recipes and A Coruña around XDC. +11:00 < pinchartl> who would join such a code camp ? +11:00 < jmondi> if it is fine to send patches to periupport as we've been doing recently... we can identify patches to look into and have them reviewed commented by you and the team +11:00 < pinchartl> jmondi: yes, it's totally fine +11:00 < jmondi> sorry, I was still on previous point +11:01 < jmondi> pinchartl: o/ +11:01 < kbingham> pinchartl, I'm more likely to head to paris than A Coruna. +11:01 < jmondi> conference wide I would go for Paris, location wide for XDC +11:02 < jmondi> but I've never been to XDC, so it might be a pleasant surprise +11:02 < pinchartl> conference-wise I think XDC is more related to multimedia than KR +11:02 < pinchartl> also, with the very limited number of tickets for KR, we might not be able to attend the conference +11:02 < neg> would join both but as stated erlier I need to go back during weekend for the proposed dates. If we are in Paris I will rejoin if we are in A Coruna maybe not +11:03 < pinchartl> if we go to A Coruna should we then try to host the code camp before the conference ? +11:04 < jmondi> neg: shouldn't you be back on the weekend of the 22? +11:05 < jmondi> pinchartl: before the conference it would be 24th to 26th, after it would span to the 28th to the Monday after? +11:05 < jmondi> more or less +11:05 < neg> jmondi: yes the 22 I need to be in Stockholm. Other dates I'm free +11:06 < jmondi> neg: both conferences are 26th to 28th +11:06 < pinchartl> jmondi: the conference is on 26-28 +11:06 < pinchartl> neg: sorry I got the dates wrong +11:06 < jmondi> Embedded recepies is 24th to 26th +11:06 < pinchartl> we should then have the code camp after the conference +11:06 < jmondi> pinchartl: I think so +11:07 < pinchartl> regardless of whether it's in Paris or Spain +11:07 < pinchartl> I think we decided for the week before because Wolfram wasn't available the week after (if I recall correctly) +11:07 < pinchartl> we if it's just multimedia, it doesn't matter +11:07 < pinchartl> s/we/but/ +11:07 < neg> if the reschdeuling of code camp to after the conference is possible it would be benificial for me and then I would vote for Spain :-) +11:09 < pinchartl> ok +11:09 < pinchartl> I'll sleep over that, let's discuss it again in the next few days +11:09 < pinchartl> Topic 4.

Status updates +09:31 < geertu> nA) What have we done since last time: +09:31 < geertu> Marek worked on U-Boot (USB VBUS and PHY on Gen2, HS400 on Gen3) and Linux +09:31 < geertu> (PCIe L0s/L1 handling on Gen3). +09:31 < geertu> Morimoto-san worked on PeriJect and Ebisu-4D export. +09:31 < geertu> Shimoda-san submitted PWM patches, and provided LTSI v4.14 snapshot +09:31 < geertu> feedback. +09:31 < geertu> Geert submmited v2 of R-Car gen3 OSC and RCLK improvements, reviewed lots +09:31 < geertu> of patches, enabled the Global Timer on Cortex-A9 MPCore SoCs, +09:31 < geertu> sub-maintained LSTI, and started looking into QEMU GPIO handling. +09:32 < geertu> B) What we plan to do till next time: +09:32 < geertu> Kaneko-san will test the M3-N CPUFreq upport. +09:32 < geertu> Marek will continue U-Boot SDHI HS400 support. +09:32 < geertu> Morimoto-san will ship Ebisu-4D boards. +09:32 < geertu> Shimoda-san will check the new LTSI v4.14 snapshot test results from the +09:32 < geertu> RVC test team, and will pave the way forward for IPMMU. +09:32 < geertu> Geert will review LTSI submissions during the merge window. +09:33 < geertu> C) Problems we have currently: +09:33 < geertu> Linus postponed v4.18 by one week, conflicting with Geert's holiday +09:33 < geertu> schedule. Hence next renesas-drivers release will be +09:33 < geertu> renesas-drivers-2018-08-21-v4.18. +09:33 < geertu> Anything I missed? +09:34 < geertu> s/submmited/submitted/ +09:35 < geertu> Lazy Summer (although it's a lot colder again)... +09:35 < Marex> geertu: well, HS400 in U-Boot is dragging on because the MMC maintainer is horribly slow to respond ... I might need to bypass him again at some point +09:35 < geertu> Marex: I'm sure you'll handle that fine +09:35 < horms> ... and for the same reasons my LTSI submission will be up to v4.18-rc8 rather than v4.18 +09:36 < Marex> geertu: just like last time ... sadly ... we might be looking for a new mmc maintainer ;-) +09:36 < geertu> horms: Np, as v4.18 will (should) be released long before the LTSI merge window closes +09:36 < horms> not before the end of this week which is when I will be sending the next round of patches +09:36 < horms> before my holiday next week +09:37 < horms> otherwise it all falls to the last week of the merge window and the wheels could easily fall off at that point +09:37 < horms> I will follow-up with any patches added between v4.18-rc8 and v4.18 +09:37 < geertu> horms: Postponing to the last week makes it more difficult for Intel to try to counter Renesas again ;-) +09:38 < horms> That is true +09:38 < geertu> (although they already know our plan anyway) +09:38 < geertu> Topic 2. Discussion Topics +09:38 < horms> But I'd rather de-risk other parts aspects of the project +09:39 < geertu> horms: Sure, thx a lot! +09:39 < geertu> morimoto: periject? +09:39 < wsa> what's with that Intel vs Renesas talk? +09:40 < horms> wsa: its a story from many years ago +09:40 < morimoto> geertu: sorry I didn't read text, but periject what ? +09:40 < horms> wsa: whereby there were two major contributors to LTSI. Renesas and Intel. And magically Intel had slightly more patches than Renesas +09:40 < geertu> wsa: Intel ended up backporting ca. 3 more patches than Renesas +09:41 < geertu> morimoto: Can we discuss periject? +09:41 < wsa> so they could claim #1 +09:41 < wsa> ? +09:41 < horms> They also caused a hidious conflict with our work +09:41 < horms> wsa: yes, that is the theory +09:42 < morimoto> geertu: yes +09:42 < wsa> horms: bastards, I will only buy AMD cpus from now on! +09:42 < wsa> ;) +09:42 < horms> wsa: I got over it in time +09:43 < wsa> "There is no politics in open source" +09:44 < geertu> morimoto: The mic is yours! +09:44 < morimoto> thanks. +09:45 < morimoto> As you know I already posted periject on gitlab. you can try it. +09:45 < morimoto> I think "tool feature" is not yet 100% but almost OK +09:45 < geertu> morimoto: You have rebased the master branch? +09:45 < morimoto> Ah... yes +09:46 < morimoto> sorry, it is still v0.x version +09:46 < morimoto> After v1.0, I will not +09:46 < pinchartl> if I may chime in on this topic (being the main source of controversy...) +09:46 < pinchartl> I think we still haven't agreed on the development process +09:46 < pinchartl> and I don't see how we can build a tool to support a process if we don't define the process first +09:47 < pinchartl> that's been my issue since the beginning +09:47 < pinchartl> the face to face discussion Morimoto-san and I had in Tokyo answered lots of my questions +09:47 < pinchartl> and I tried to summarize the process discussions on the periperi mailing list +09:47 < pinchartl> but the mail thread quickly died +09:47 < pinchartl> to word this differently, I think we need to agree about what we want to do before doing it +09:48 < morimoto> 1 question. what is your problem ?? +09:49 < wsa> what are the open questions there? I am fine with trying morimoto-san's tools for now... +09:49 < damm> i think we should split the process discussion from the tool +09:49 < damm> that said, i agree that process is important +09:49 < pinchartl> morimoto: my issue is that we still don't know what we want to do +09:49 < pinchartl> there have been lots of bikeshedding discussions about the tool +09:50 < pinchartl> about the format of stored data +09:50 < morimoto> OK, yes, let's split the topic +09:50 < pinchartl> and other topics +09:50 < pinchartl> and to answer those questions, we first need to know what we want to do +09:50 < pinchartl> at the moment, I see a tool, and I have no idea how to use it +09:50 < damm> i don't disagree +09:50 < pinchartl> for instance +09:50 < pinchartl> for your last report +09:50 < pinchartl> you tried to use the tool to generate the e-mail +09:51 < pinchartl> there were no B) and C) +09:51 < pinchartl> which isn't surprising +09:51 < wsa> we are at the tool level again +09:51 < pinchartl> as the tool doesn't support tracking future work plans at a bi-weekly level +09:51 < pinchartl> nor does it support tracking blockers +09:51 < wsa> I agree that "reporting emails" should be maybe a second or third step for the tool +09:51 < pinchartl> so, as an experiment, you tried adding that information to the task description +09:51 < pinchartl> it then ended up in the generated report +09:52 < pinchartl> but that's a hack +09:52 < damm> but does it blend? +09:52 < pinchartl> and if we start using a tool without knowing what we want to do it with +09:52 < pinchartl> we'll keep making hacks like that +09:52 < pinchartl> in different ways, for different people +09:52 < pinchartl> it will quickly become unusable +09:52 < wsa> we first need to deal with handling tasks, or? +09:52 < pinchartl> personally speaking, the logical order would be +09:53 < pinchartl> 1. what are the issues we have? +09:53 < pinchartl> 2. how do we want to solve them? +09:53 < pinchartl> 3. how do we implement tools to support that? +09:53 < wsa> and I would still like to understand why we can't use the tool for that right now... +09:53 < pinchartl> if we start by 3, then 2, then 1, I don't see how it could work :-) +09:53 < morimoto> wsa: +1 +09:54 < morimoto> Many times I explain it ... +09:54 < wsa> and I think it is not only about the issues we have but also about the issue Morimoto-san is having +09:54 < wsa> issues +09:54 < pinchartl> wsa: we have a mostly free-formed text format as a database. that won't work, we will end up with one format per person depending on personal preferences +09:54 < damm> pinchartl: i thought that it was the germans that liked process and order? +09:54 < pinchartl> see the discussion of 1 task per file vs. several tasks per file +09:55 < pinchartl> or Morimoto-san's today's e-mail report with free-formed B) and C) in the task description +09:55 < pinchartl> we haven't really started using this, and it's already forking :-) +09:56 < damm> my opinion is that people should use the tools that they like +09:56 < wsa> I do like processes, but there is just talk :) +09:56 < pinchartl> at the moment I feel that we're being given a database engine and we're told it's our bug and task tracker +09:56 < damm> but some interface/format is needed together with a known process +09:57 < pinchartl> what I'd like to get is jira/bugzilla/whatever. not those tools in particular, but something that operates at a similar level. with a defined work flow +09:57 < damm> how about the people that like processes come up with a process proposal? +09:58 < damm> i am for sure in the process camp +09:58 < damm> the we have a tool camp as well +09:58 < pinchartl> damm: let me locate the e-mail thread +09:58 < damm> once both are in semi-ok order we merge +09:58 < morimoto> I explained many times, but, I can create "Tool", but, you can create "Rule" +09:58 < damm> how many people are in the pro-process discussion camp? +09:59 < kbingham> I'm in the ... I want something that works camp ... +09:59 < damm> obviously not morimoto-san +09:59 < wsa> okay, let me summarize my take: +09:59 < pinchartl> morimoto: but my point is that the tool should be based on the rules, not the other way around +09:59 < damm> obviously laurent likes process +09:59 < kbingham> And ... I'm confused why we're writting our own tools when opensource tools already exist :) +09:59 < morimoto> pinchartl: yes, and, no my opinion +10:00 < morimoto> My opinion is like this +10:00 < damm> kibingham: i guess we need to know which problem we are solving first +10:00 < wsa> even the current process works for me as groupleader. not perfect, but works. I see Morimoto-san has problems reporting our progress upwards. I'd surely like to have this issue solved, it is important for all of us. +10:01 < morimoto> You can use Emacs, or VIM. it is editor. but, what you can write is under your rule. +10:01 < pinchartl> "Re: [periperi] Peri Tool Next" from "Date: Sat, 14 Jul 2018 05:27:30 +0300" +10:01 < pinchartl> Message-ID: <2412691.0qdXsgRgLR@avalon> +10:01 < wsa> I don't think I need details on this, because I'd think there is a lot of internal information and culture involved. +10:01 < damm> so why can't we simply do a work split? +10:01 < damm> break out the process discussion into a group that cares? +10:02 < damm> and figure out what we _need_ to do +10:02 < pinchartl> damm: that would work for me +10:02 < damm> then we can apply that to tools or whatnot +10:02 < damm> so currently the process group includes pinchartl and myself +10:03 < morimoto> my opinion is, try 1st, fix 2nd, rule 3rd :) +10:03 < damm> morimoto: that's why you are not in the process group =) +10:03 < morimoto> ok :) +10:03 < damm> morimoto: you are however very welcome to join if you'd like +10:03 < morimoto> I still don't understand what is the issue... +10:04 < damm> morimoto: you and i have discussed this before +10:04 < pinchartl> morimoto: ok, to make it very simple, my first issue is that with today's version of the tool, file format and documentation, I have no idea how to use it +10:04 < damm> if you get interested in the process let me know +10:05 < damm> pinchartl: you and i are at the same wave length +10:05 < morimoto> pinchartl: yeah, I don't know too. thus, it is "trial" +10:05 < pinchartl> damm: I don't know if that's a good or bad thing :) +10:05 < damm> but lets give morimoto-san freedom to poke around +10:05 < pinchartl> morimoto: shouldn't the trial phase be done separately from the production phase ? :-) +10:06 < damm> you are using process-think now =) +10:06 < damm> lets take that elsewhere +10:06 < morimoto> My opinion is, +10:06 < wsa> damm: I assume you know what is needed from the Renesas side for that process? +10:07 < damm> sort of +10:07 < morimoto> we can use tool to get all information. But we don't know how many information we have or we need, so far +10:07 < morimoto> So far I know is +10:07 < morimoto> 1) task, 2) BSP list +10:08 < morimoto> For each purpose, we can use 1) task/mm for example, 2) task/bsp, etc +10:08 < morimoto> each folder has each rule +10:08 < morimoto> few rule is it should use "clear Title", etc +10:09 < morimoto> we can create each rule for each purpose / each folder +10:09 < morimoto> Because of this, "tool" have limited rule +10:10 < morimoto> If you want to have "fixed" fule/format, you can create it +10:10 < morimoto> and force it by git hook ? +10:10 < morimoto> it is operation rule, not tool rule +10:10 < morimoto> this is my basic idea +10:11 < pinchartl> morimoto: I think the tool should enforce operation rules. otherwise they won't be enforced, and the "database" will be "corrupted" all the time +10:11 < damm> morimoto: this discussion is similar to someone wanting to cook a pancake and asks how to do it, but the answer is a swiss army knife. =) +10:12 < morimoto> pinchartl: tool has operation rules. like "status:" tag +10:12 < wsa> how urgent is all this? +10:12 < morimoto> ? sorry, what does your "operation rule" ? +10:12 < wsa> I am under the impression Morimoto-san may need the tool to create proper reports so we can be evaluated correctly +10:12 < wsa> but i may be wrong +10:13 < damm> wsa: i have my own tools to monitor upstream contribution rate for each group +10:13 < pinchartl> wsa: I think you're right, but it's not just the tool that's needed for that, it's also the data. reports can't be created before we all start using the tool and keep the data up to date +10:13 < morimoto> wsa: creating reports is option, not purpose +10:13 < wsa> ok +10:13 < wsa> that relieves me +10:13 < damm> and to avoid spending time unwisely i don't bother you with that unless things are not progressing as expected +10:14 < wsa> I have absolutely zero doubts in trusting Magnus and Laurent figuring out an awesome process... +10:14 < damm> it would be interesting to hear how shimoda-san and morimoto-san would like to receive information how to handle those BSP upporting lists +10:15 < wsa> ... yet they are both probably the busiest people we have? +10:15 < damm> are we in a rush somehow? +10:16 < wsa> that was my initial question. i thought so and I am happy I was wrong :) +10:16 < pinchartl> wsa: I think we're all busy. I agree however that I might be one of the people who sometimes has the hardest time setting priorities straight :) +10:16 < damm> pinchartl: it is good to see that someone cares +10:16 < damm> pinchartl: shall we take that process discussion elsewhere? +10:17 < pinchartl> and as we're all busy, if this new tools requires spending more time to keep data up to date, I'm pretty sure it won't happen. I don't see how it could be adopted unless it makes everybody's life easier +10:17 < pinchartl> damm: sure. on the mailing list ? or do you have another preference ? +10:18 < damm> pinchartl: lets use private email to schedule a video conference you and me +10:19 < pinchartl> is anyone else interested ? +10:20 < geertu> I'm interested in the outcome +10:20 < kbingham> perhaps in the outcome of discussions :) - and the list of features required +10:21 < pinchartl> alright +10:21 < pinchartl> damm: seems like we have a date then :-) +10:21 < damm> pinchartl: yay +10:22 < pinchartl> ok, let's do that +10:23 < wsa> damm: you have a second now to chat (IRC or Hangout)? +10:25 < pinchartl> damm: mail sent +10:26 * kbingham posts "PeriZilla" to "PeriPeri" and awaits to be laughed at +10:27 < pinchartl> damm: seems like our e-mails have crossed each other :) +10:29 < geertu> kbingham: is there a perl-bugzilla, too? +10:29 < kbingham> geertu, If not you could write one :D +10:29 * geertu notices the similarities between peri and perl +10:30 < uli_> geertu: bugzilla itself is written in perl; i'd be surprised if there weren't +10:30 < geertu> Are we finished with core? +10:30 < kbingham> geertu, https://devzing.com/blog/index.php/access-bugzilla-from-perl/ +10:30 < geertu> Any other topics to discuss? +10:34 < wsa> damm: you have a second now to chat (IRC or Hangout)? +10:34 < damm> wsa: hangouts pls +10:34 < pinchartl> geertu: not for me.

+09:43 < geertu> memory detection +09:43 < Marex> geertu: oh that +09:43 < Marex> geertu: nope, nothing +09:44 < Marex> geertu: I can just implement the decoder for the ATF memory layout tables and put it in ... +09:44 < damm> we have no ATF code in upstream yet, right? +09:44 < shimoda> Marex: you're right :) +09:44 < damm> but i recall Marex doing some work somewhere +09:44 < Marex> damm: not yet, sorry +09:44 < Marex> damm: I upported the D3/V3M ATF to 1.0.22r2 (latest) +09:45 < Marex> damm: I didnt start feeding it upstream yet +09:45 < damm> to have at least one known working system with autodetection, perhaps we can upstream ATF support for one board/SoC and complete upstreaming of the u-boot portion too? +09:45 < Marex> damm: the U-Boot portion is easy I think +09:46 < Marex> damm: from what pinchartl told me, the ATF just puts memory layout tables in RAM, so U-Boot can parse that and fill linux DT with that information +09:46 < damm> i suppose we want something robust so in case ATF doesn't support memory detection we still have working upstream u-boot +09:47 < Marex> damm: fall back to small amount of memory that's always present ? +09:47 < damm> sure +09:47 < damm> i suppose we want to disconnect the upstreaming/upgrade path of u-boot from ATF +09:47 < geertu> Seems like there's also an H3ULCB with 8 GiB of RAM? +09:48 < Marex> damm: yes, those things should be separate +09:48 < damm> but starting with ATF must make sense so we don't implement code in u-boot that can't be merged +09:48 < Marex> damm: there should be a minimum version requirement for ATF on which U-Boot and Linux works fine, but that's about it +09:49 < Marex> damm: start with ATF how ? by patching it support passing some more sane memory info to the upper layers ? +09:50 < damm> i guess since everything is out of tree when it comes to ATF we don't want to make it more difficult than necessary to adopt upstream code +09:50 < damm> i would say upstreaming of ATF for one platform +09:50 < Marex> damm: sure +09:51 < damm> some basic minimal support level +09:51 < damm> and then add that auto-detection bit +09:51 < damm> that would make sense to me at least +09:51 < Marex> damm: the autodetection can be implemented with current ATF already, the question is whether that (those tables that ATF populates) can be considered an ABI +09:52 < damm> then we can handle features and other SoCs/board incrementally after that +09:52 < damm> out of tree ABIs are not exactly smelling good in my book +09:52 < Marex> damm: right +09:53 < damm> so shall we get Renesas to approve upstreaming of H3 ATF for instance? +09:53 < damm> would anyone including Marex and Uli be interested in that kind of work? +09:54 < geertu> damm: Yes please (for upstreaming) +09:54 < Marex> damm: I have upstreaming of the ATF for D3/V3M on my list I wrote in Japan +09:55 < damm> ok so lets check with Renesas about preferred platform out of D3/V3M/H3 +09:55 < damm> I suppose we can make use of memory autodetect on H3 mainly +09:55 < Marex> :-) +09:55 < damm> but hey, this is just an ordering problem really +09:56 < geertu> For H3/M3-W/M3-N, the memory is on the SiP (for M3-N that may not be true for production SoCs) +09:56 < geertu> Is there any ID on the SiP that can be read? +09:57 < damm> that would indeed be nice +09:57 < geertu> Which brings us to [PATCH 0/8] arm64: dts: renesas: Break out R-Car H3 and M3-W SiP"[PATCH 0/8] arm64: dts: renesas: Break out R-Car H3 and M3-W SiP" (https://www.spinics.net/lists/devicetree/msg173820.html) again ;-) +09:58 < geertu> No, we don't want _more_ DTS files to maintain... +09:58 < Marex> geertu: but if it's SiP, someone can populate pretty much random DRAM chip on it, right ? +09:58 < Marex> geertu: it's just a matter of soldering it on +09:59 < geertu> Marex: the same is true for boards with an SoC instead of an SiP +09:59 < geertu> Although soldering the SiP may be a tiny bit harder ;-) +10:00 < geertu> Anyway, we're deviating. +10:00 < geertu> So: +10:00 < geertu> 1) upstream ATF for one R-Car Gen3 SoCs +10:00 < geertu> 2) update ATF for memory auto-detected +10:00 < geertu> 3) update U-Boot for memory auto-detect +10:00 < geertu> Sounds good? +10:00 < damm> yeah perfect +10:00 < damm> thanks +10:01 < Marex> geertu: sounds good +10:01 < damm> oh one thing +10:01 < Marex> geertu: so we just need the approval for H3/M3x or get me a physical D3/V3M :-) +10:01 < damm> will uli simply hand over stuff to Marex then? +10:02 < uli___> i would prefer that +10:02 < damm> lets do that then +10:02 < shimoda> damm: about ATF upstreaming, does it need Renesas side help? or, we can upport from in-house code anyway? +10:02 < damm> shimoda: maybe q&a is needed +10:03 < damm> shimoda: but apart from that i don't expect much help is needed +10:03 < Marex> shimoda: I think the goal would be to move in-house code (after cleanup and maybe rewrite) to upstream ... and then there would be no more inhouse code :) +10:03 < damm> Marex: what do you think? +10:05 < shimoda> damm: i see... I heard BayLibre tried upstreaming ATF but they have many questions to Ito-san, but since Ito-san and renesas ATF team are very busy, so no progress now... ;) +10:05 < Marex> damm: I might have a few questions if there are registers which are not in the documentation or weird things happening, but in general from what I saw, not much help would be needed +10:05 < damm> so letting Marex use the in-house code as sample and then he can decide by himself how to handle upstreaming? +10:05 < damm> shimoda: maybe our friends at BL will be happy with some assistance then +10:05 < geertu> Any political conflict with BayLibre? +10:06 < damm> don't think so +10:06 < damm> so lets see how Marex will accelerate this activity =) +10:06 < geertu> Great! +10:07 < shimoda> damm: should I ask Ito-san about who is trying to upstream in BayLibre? +10:07 < geertu> Last(?) topic: BSP and periject? +10:07 < damm> shimoda: sure, and please ask about what target platform they focus on +10:07 < Marex> damm: can I get a go/no-go when you check with BayLibre and input on which SoC I should use for upstreaming (H3/M3x/D3/V3x) ? +10:08 < damm> sure +10:08 * pinchartl takees the microphone +10:08 < damm> will let you know +10:08 < Marex> damm: thanks, so in the meantime I'll keep haggling about the PCI +10:08 * geertu releases +10:08 < shimoda> damm: i got it +10:08 < pinchartl> I attended the "periperi process meeting yesterday" +10:08 < Marex> on both U-Boot and Linux front no less , sigh +10:08 < Marex> damm: thanks +10:08 < pinchartl> which turned out to be a discussion between Magnus and I :-) +10:09 < pinchartl> we spent two hours going around many topics +10:09 < morimoto> wow +10:09 < jmondi> I missed it was yesterday, my bad +10:09 < pinchartl> no worries +10:10 < pinchartl> we decided to segment the problem, as handling everything in one go would be a too large task +10:10 < pinchartl> so the topic I'd like to discuss today is handling of the BSP patches +10:10 < pinchartl> today's situation is as follows (in a very summarized form) +10:10 < morimoto> This is good timing, we got new upport list from BSP team +10:11 < pinchartl> we, the upstreaming team, work on the upstream kernel +10:11 < pinchartl> Renesas consumes the result of our work, through renesas-drivers, and creates BSPs +10:11 < pinchartl> there are several layers there, as not all kernel code is in the public BSP (I'm thinking about codec drivers for instance) +10:11 < pinchartl> and I'm sure there are customer trees as well +10:12 < pinchartl> but in a nutshell, we get a BSP +10:12 < damm> (or a bucket of mud as i referred to it) +10:12 < pinchartl> the BSP is the result of a process that takes the upstream kernel, identifies issues (bugs, performance problems, missing features...), and fixes those issues +10:13 < pinchartl> that process, internally, uses various means of bug tracking (including lots of excell spreadsheets from what I've been told), to which we have no access externally +10:13 < wsa> all Japanese, too, probably? +10:13 < neg> damm: :-) +10:14 < pinchartl> as an upstreaming team, we strive for feature completeness, stability and performances +10:14 < pinchartl> so it is of value to us to know about the issues that have been identified +10:14 < pinchartl> we have started efforts to implement automated tests ourselves to catch regressions and other problems +10:15 < pinchartl> but given that we are resource-constrained, we can't match for now all the testing effort done internally by Renesas +10:15 < pinchartl> and by Renesas' customers (I've been told that customers are the best source of bug reports) +10:15 < pinchartl> wsa: and yes, lots of information is in Japanese +10:15 < pinchartl> so that's the current situation +10:15 < pinchartl> now, where do we want to go ? +10:15 < pinchartl> *ideally* +10:16 < pinchartl> we should get access to a common issue tracker, with all the information available for all identified issues +10:16 < pinchartl> that's something I'd like to happen, but it's a very long term project +10:16 < pinchartl> we can't expect that in the short or mid term +10:17 < pinchartl> so today, our largest source of information about issues in the upstream kernel is the BSP +10:17 < pinchartl> as most BSP commits fix an issue (alleged or real) +10:18 < pinchartl> for that reason, Magnus and I agreed that we need to base our process to achieve feature completeness, stability and performances partly at least on the BSP commits +10:19 < pinchartl> furthermore, we are, at least partly, evaluated on how we reduce the delta between the BSP and upstream +10:19 < pinchartl> and thus on the amount of BSP code that we "upport" +10:19 < pinchartl> "upporting" here means either direct upporting, or development of equivalent fixes +10:19 < pinchartl> so it's often more about superseding the BSP commits than really uppporting them +10:20 < pinchartl> it's thus useful internally for Renesas, at least if my understanding is correct, to track how BSP commits are replaced +10:20 < pinchartl> we thus need a list of BSP commit, associated with a status, in order to track our progress +10:21 < pinchartl> both on our side, to make sure no BSP commit falls through the cracks, and on Renesas' side, to evaluate progress +10:21 < pinchartl> we have such a list, in a shared git tree +10:21 < pinchartl> but there's one issue that I haven't mentioned yet +10:21 < pinchartl> BSP commits come with very little information +10:21 < pinchartl> there's often no commit message +10:21 < pinchartl> and when there's a message, it's usually terse +10:22 < pinchartl> there's usually no information about which platforms are affected by the issue +10:22 < pinchartl> or how to reproduce it +10:22 < wsa> ^ that! +10:22 < pinchartl> or the userspace use cases +10:22 < pinchartl> we are thus often left in the dark +10:23 < pinchartl> and we randomly send e-mails to Morimoto-san, sometimes CC'ing the author of the BSP commit, asking for clarifications +10:23 < pinchartl> that's not a very efficient process +10:23 < pinchartl> as information gets lost somewhere in mailing list archives +10:23 < pinchartl> or in private e-mails +10:24 < pinchartl> so Magnus and I are proposing storing additional information in the database of BSP commits +10:24 < pinchartl> which would become, in a way, an interface with the BSP team +10:24 < pinchartl> when a new BSP is released, the BSP team will add commits to the database (they already do today) +10:25 < pinchartl> and our proposal is to add a way for the BSP team to add a description for each commit +10:25 < pinchartl> ideally that wouldn't be needed +10:25 < pinchartl> as all information we need should be in the commit messages +10:26 < pinchartl> but realistically that won't happen +10:26 < pinchartl> we should try to get there gradually, but things will never be perfect anyway +10:26 < pinchartl> so, the idea is to have, for each BSP commit, a status, and a description +10:26 < pinchartl> if we need more information we can just mark the commit as requiring information +10:27 < pinchartl> all that would still be stored in a git tree, as it is today +10:27 < pinchartl> and both us and the BSP team would have access to that tree +10:27 < pinchartl> we need to extend the storage format used today for the BSP commits +10:28 < pinchartl> and, on top of that, tools could also be developed +10:28 < pinchartl> as long as the storage format is defined, we could even have multiple tools, command-line-based, GUI, web-based, if someone has time to spend :-) +10:29 < geertu> Sounds good to me. thx! +10:29 < pinchartl> to conclude on the topic, what we'd like to agree on, is the data storage format, and the process to handle BSP commits +10:29 < kbingham> Another git-backed-information-storage tool I came across lately might be of interest on this topic: https://github.com/sit-fyi/sit +10:29 < pinchartl> (who adds them, who updates them, how, ...) +10:29 < pinchartl> now the mic is yours, we take questions :-) +10:30 < pinchartl> kbingham: thanks for the link +10:30 < damm> may i raise two points from my side? +10:31 < pinchartl> sure +10:31 < damm> thanks for sharing the details very well +10:31 < damm> i just wanted to mention two things +10:31 < damm> 1. we should remember that BSP is one source of issues +10:32 < damm> issues may come from a mailing list too for instance +10:32 < damm> 2. we will have multiple buckets in progress at any given time +10:32 < kbingham> Or issues /we/ find in our testing :) +10:32 < pinchartl> damm: regarding the first item +10:32 < pinchartl> sure +10:33 < pinchartl> we also get requests or bug reports by e-mail +10:33 < wsa> we also find bugs by ourselves :) +10:33 < pinchartl> (both e-mails from Renesas and from third-parties, in public or private e-mails) +10:33 < pinchartl> possibly on IRC +10:33 < damm> yeah, so no need to keep a too bsp-upport centric view +10:33 < pinchartl> and there are bugs we find ourselves, yes :-) +10:33 < pinchartl> so yesterday we also discussed the need to have an issue tracker +10:34 < pinchartl> which would be at a level just above the BSP commit tracker +10:34 < pinchartl> but that's a second step, I don't want to try and solve all problems in one go as I explained in the beginning +10:34 < damm> totall agree, thanks! +10:34 < pinchartl> tracking BSP commits is the low-hanging fruit in my opinion +10:34 < pinchartl> as we know it's useful and needed +10:34 < pinchartl> (both for us and Renesas) +10:35 < pinchartl> the information we need to track are limited, the workflow is simple +10:35 < pinchartl> so it can be implemented in a relatively simple way +10:35 < pinchartl> once we get there I'd like to move to issue tracking +10:35 < pinchartl> of course if someone has too much free time, we can work in parallel :-) +10:36 < jmondi> one question: instead of going in the "BSP -> issue tracker" direction, shouldn't it be smarter to setup an issue tracker and ask BSP to use it? so that it's there already for us to use if we have bugs to list too +10:36 < geertu> Public bug reports (email, irc) are usually fixed quicker, mostly because there's a direct link with the reporter, leading to more accurate bug information. +10:36 < jmondi> it would also force BSP to reason in terms of "issue -> patch series" not the other way around +10:36 < pinchartl> jmondi: that's a very good question +10:37 < pinchartl> and I think the answer is yes +10:37 < pinchartl> but I'm concerned about how to get there +10:37 < pinchartl> I'd like to tell the BSP team today that we'll stop taking BSP commit directly, and that they should file proper issue reports +10:37 < pinchartl> but I doubt they will +10:38 < pinchartl> my hope is that, but creating a BSP commit tracker that they feed as they do today +10:38 < wsa> I'd think our possibilty to "force" something onto the BSP team is limited +10:38 < jmondi> run a $BUGZILLA hosted by renesas? +10:38 < jmondi> I'm sure it might take a long time, but... +10:38 < wsa> I think we should aim for cooperation +10:38 < pinchartl> with an additional feature of having a description they can fill as well +10:38 < pinchartl> will let us push them to fill descriptions +10:38 < pinchartl> once they get used to that +10:38 < wsa> They probably have lots of other issues/people to deal with +10:39 < jmondi> wsa: as well as we do +10:39 < pinchartl> we could get better commit messages in the first place +10:39 < pinchartl> and it might be easier to ask them to transition from BSP commit tracking to issue tracking too +10:39 < pinchartl> maybe I'm too optimistic though +10:39 < jmondi> wsa: I just don't think it's efficient we go through the process "Oh look a series, who knows what it tries to solve" +10:39 < wsa> it isn't +10:39 < pinchartl> but the only way I see to get better information is to make it more painful for them when they don't provide the information :-) +10:40 < pinchartl> if a commit has no commit message, we just send it back, asking for information +10:40 < wsa> I could imagine a workshop +10:40 < jmondi> so if we spend a day trying to figure out what they meant to solve, they can spend 10 minutes creating issues, and linking there the series that tackle the issue +10:40 < pinchartl> if we always do that consistently and stop trying to guess what the commits do, they might get the message +10:40 < wsa> or any other way to give examples +10:41 < jmondi> sorry, I don't mean to be rude, but I don't get why we have to treat them as uncapable of adhering to a process +10:41 < pinchartl> our responsability will be to mark the BSP commits we supersede +10:41 < jmondi> what's hard in "if you want to have a commit usptreamed, open an issue" +10:41 < Marex> jmondi: the redmine running at osdr has a tracker plugin +10:41 < pinchartl> the BSP team's responsability will be to provide us with detailed information about the issues +10:42 < jmondi> pinchartl: yup +10:42 < wsa> is there a language barrier? +10:42 < pinchartl> jmondi: the hard part in "if you want to have a commit usptreamed, open an issue" is that *they* don't want to get commits upstreamed +10:42 < pinchartl> we do +10:42 < pinchartl> because we're asked to do so by Renesas +10:42 < jmondi> s/we/Renesas +10:42 < pinchartl> it's a case of left hand not talking to the right hand +10:42 < wsa> I see Shimoda-san and Morimoto-san translating a lot +10:43 < jmondi> fine, so that's an internal Renesas issues then :) +10:43 < pinchartl> as I understand it, we're part of an external feedback loop that goes through multiple teams internally +10:43 < jmondi> a team in Renesas wants BSP commits to be usptreamed, BSP doesn't care... that's an issue +10:44 < pinchartl> (I don't know exactly how it works internally of course) +10:44 < Marex> jmondi: big company, multiple departments with different management people and management strategies +10:44 < jmondi> I understand it's not an easy issue +10:44 < Marex> jmondi: some want FOO, others want BAR +10:44 < jmondi> :) +10:45 < damm> discussing with Renesas about how to improve the process must be a good thing +10:47 < pinchartl> so, time for a conclusion +10:47 < pinchartl> damm: will you do the honours ? :-) +10:47 < horms> <2c> It seems to me that this is primarily a process rather than a tooling issue. And a cross-team process issue at that.

I agree about the mottainai +10:53 < morimoto> They are busy guy +10:53 < pinchartl> I expect them to be busy, yes +10:53 < morimoto> pinchartl: Sorry, I don't know about English version of it +10:53 < geertu> The advantage of anything git-based over redmine is that it works offline. +10:53 < damm> and lacks a gui +10:53 < morimoto> Thus, me or Shimoda-san pick-up, and do something is possible +10:54 < pinchartl> (https://en.wikipedia.org/wiki/Mottainai) +10:55 < damm> you could consider utf8 mottainai compared to shift-jis +10:55 < shimoda> morimoto: Redmine can change the language by 個人設定 +10:56 < pinchartl> damm: https://upload.wikimedia.org/wikipedia/commons/b/ba/JIS_and_Shift-JIS_variants.svg +10:56 < morimoto> shimoda: I mean "mottainai" English, not "Redmine" :) +10:57 * geertu wonders what's the "R-Car Emotion Engine" (https://elinux.org/Emotion_Engine_SDK_Image_preparation_guide) +10:57 < shimoda> shimoda: oops, sorry :) +10:57 < jmondi> morimoto: you and shimoda-san are the ones taking the most burden from this, translating back and forth, asking question etc.. there's no way your team can agree on a process with BSP to mediate all upporting requests through redmine? +10:58 * kbingham clicks geertu's link and wonders who RKDM is... +10:58 < geertu> jmondi: Or rebase -i and add the info to the commits (excessive (sic) information under the "---" line?) +10:58 < jmondi> again, I think "forcing" them to reason through "issue first -> then patches" would make things a lot smoother +10:59 < pinchartl> geertu: we would lose commit IDs, I don't think that would be very usable in the end +10:59 < damm> pinchartl: that table is geek t-shirt material for sure +10:59 < pinchartl> if we could get back to the topic at hand :-) +10:59 < jmondi> geertu: they want fixed format and I feel like an issue request on redmine would force them to use a standard tool and not think about "formats" +10:59 < pinchartl> 1. do we want to replace the git BSP commit list with redmine ? +11:00 < pinchartl> 2.1. if so, who will create the redmine issues ? +11:00 < damm> i dont think so +11:00 < pinchartl> 2.2. if not, do we agree with the process that I have proposed ? +11:00 < pinchartl> I would personally answer no to the first question because I can't see a good answer for 2.1. +11:00 < damm> worth discussing perhaps, but in a different setting? +11:01 < morimoto> pinchartl: "git BSP commit list" = periupport ? +11:01 < pinchartl> damm: would you like to take this internally and report the result of the discussions in the next meeting ? (or possibly before) +11:02 < damm> sure +11:02 < Marex> geertu: probably some AI thing ? +11:02 < pinchartl> morimoto: yes, git BSP commit list = periupport, but with a different format to allow adding descriptions (including platforms, userspace context, use cases, ...) +11:02 -!- horms_ [~horms@penelope-musen.amstelveen.horms.nl] has joined #periperi +11:02 < geertu> pinchartl: Or store it in periject? +11:02 < morimoto> Ahh, OK +11:03 < wsa> i think the biggest difference between periupport and what you proposed is a clear "status" +11:03 < wsa> like "need info" +11:03 < morimoto> geertu: yeah agree. how about to use periject with such tag ? +11:03 < pinchartl> geertu: I want to agree on the process and interface with the BSP team (a.k.a. data format). tooling is a separate discussion, on top of this +11:03 < wsa> currently this is hidden in the free form text field and might be easy to miss +11:03 < geertu> pinchartl: Do you want to script redmine queries? +11:03 < pinchartl> wsa: yes, we need a status field, and at least a comment field +11:04 < pinchartl> (and possibly other fields such as platform, although that could possibly be included in the comment/description) +11:04 < wsa> so, a status field like, "worked on", "accepted", "rejected", "need info" etc would be a good addition IMO +11:05 -!- horms [~horms@ip4dab7138.direct-adsl.nl] has quit [Ping timeout: 252 seconds] +11:05 < pinchartl> depending on the result of the internal discussions, I'll try to propose a format +11:06 < pinchartl> can that be our conclusion for today ? +11:07 < damm> seems all good to me at least +11:07 < neg> I think the discussion have been real good and I agree with pinchartl. However I'm a bit unclear how this new periupport repo will be handeled by us, do the whole team push directly to it? +11:07 -!- horms_ [~horms@penelope-musen.amstelveen.horms.nl] has quit [Ping timeout: 265 seconds] +11:08 < pinchartl> neg: that's part of the process that needs to be defined. I think we should all be allowed to push, yes +11:08 -!- horms_ [~horms@penelope-musen.amstelveen.horms.nl] has joined #periperi +11:08 < kbingham> What ever the resulting solution - we /need/ to have global access to add comments etc. +11:08 < neg> I think maybe group leaders should be involved in changes somehow but sending patches on ML seems a bit of extra workload for them +11:09 < geertu> neg: Agreed +11:10 < jmondi> what about 'locking' the master branch and have group leaders cherry-picking from developers' branches? +11:10 * morimoto I will talk this topic with BSP team +11:10 < jmondi> I agree sending periupport patches is a bit of a waste, but I would like to make sure my udpates to the upport list are validated first.. I would have screwed up a few times already +11:11 < pinchartl> jmondi: think about a regular issue tracker for a minute, like jira for instance. imagine how it would be if you couldn't modify anything yourself and always had to go through someone else :-) +11:12 < jmondi> well, not always, updates to periupport happens weekly at the most to me +11:12 < pinchartl> and they should happen more frequently +11:13 < pinchartl> whenever you get a patch accepted upstream, the corresponding BSP commit(s) should be updated +11:13 < neg> I think we reached the point where we need to empolye a secretarial pool :-) +11:13 < jmondi> well, usually it takes me ~week to upport a series +11:13 < jmondi> neg: seconded +11:13 < pinchartl> anyway, I propose closing this topic to start the multimedia meeting. we're only an hour and 15 minutes late :-) +11:14 < jmondi> pinchartl: we're not -only- upporting, I hardly see me updating periupport daily +11:14 < jmondi> ok, sorry +11:14 < jmondi> I'll get back when the secretarial pool selection process topic is raised again +11:15 < pinchartl> geertu: anything else for the core group ?

By the way, I'm not familiar about PCIe, so I'd like get a simple question for asking HW guys from you :) If simple, I think I can translate it to Japanese +09:15 < wsa> uli___: what about this series "serial: sh-sci: Use pm_runtime_get_sync()/put()"?

"what happens when the Gen3 PCIe controller receives PM_Enter_L1 DLLP from the PCI device?" +09:17 < shimoda> Marex: by the way, R-Car Gen3 supports PCIe spec Rev.2.0, not Rev.3.0 +09:17 < wsa> So, any questions from your side? +09:17 < wsa> I have one but we can do this last +09:18 < Marex> shimoda: From PCI EXPRESS BASE SPECIFICATION v3.0 , the Gen3 PCIe controller should send PM_Request_ACK . Does it ? +09:18 < Marex> shimoda: I think it does not, it needs to be forced to do so by setting this bit 31 in PMCTRL +09:19 < Marex> shimoda: I only have the newer version of the PCIe spec, 3.0, but the L0-L1 transition procedure is the same +09:19 < wsa> My question is about watchdog and clocks +09:20 < Marex> shimoda: the v3.0 of the spec covers PCIe 1.0,2.0,3.0, I just ignore the PCIe 3.0 specific extra parts +09:20 < wsa> if we don't have NOWAYOUT enabled, it does RuntimePM clock handling as our other drivers +09:20 < wsa> if NOWAYOUT is set, we want to enable it once and never disable it again +09:21 < wsa> I could skip pm_runtime_put on remove(), but isn't that kind of leaking? +09:22 < wsa> Is pm_runtime_forbid() better? Yet, it also increments the ref counter +09:22 < wsa> Any ideas on how to do that properly? +09:22 < Marex> shimoda: do those three questions above make it easier to inquire about the PCIe or shall I rephrase them ? +09:23 < geertu> pm_runtime_forbid() sounds like a good solution to me, also in wording (nowayout -> forbid) +09:23 < wsa> yet, there will also be no pm_runtime_allow to balance it +09:25 < wsa> ok, seems I will try pm_runtime_forbid and CC the rpm people +09:25 < geertu> Will it ever call pm_runtime_put() if WDOG_NO_WAY_OUT is set? +09:25 < geertu> watchdog_stop() returns -EBUSY +09:27 < wsa> 1004 if (watchdog_active(wdd) && +09:27 < wsa> 1005 test_bit(WDOG_STOP_ON_UNREGISTER, &wdd->status)) { +09:27 < wsa> 1006 watchdog_stop(wdd); +09:27 < wsa> 1007 } +09:28 < geertu> nowautout assumes it has been started (once), right? +09:28 < wsa> according to the docs, this will only trigger for !NOWAYOUT +09:29 < shimoda> Marex: I'm afraid but, would you send an email about your questions?

Status updates +09:39 < Marex> shimoda: I'll keep you posted on the ATF news ASAP +09:39 < geertu> A) What have we done since last time: +09:39 < geertu> Kaneko-san got M3-N CPUFreq merged. +09:39 < geertu> Marek cleant up the TMU driver in U-Boot slightly. +09:39 < geertu> Morimoto-san worked on PeriJect and Ebisu-4D export (arrived at Simon/Geert). +09:39 < geertu> Niklas fixed the return type of dma_set_max_seg_size(). +09:39 < geertu> Shimoda-san says the Renesas Vietnam test team finished testing of the new +09:39 < geertu> LTSI v4.14 snapshot, and he submitted a patch to revise usb2 properties on +09:39 < geertu> R-Car Gen3. +09:39 < geertu> Geert reviewed the second socfpga and additional rcar-i2c submissions for +09:39 < geertu> LTSI, worked on defconfig updates, tested s2ram on Ebisu-4D (fails), sent +09:39 < geertu> his first clk and pfc pull requests for v4.20, and worked through his +09:39 < geertu> holiday backlog. +09:39 < geertu> B) What we plan to do till next time: +09:39 < geertu> Morimoto-san will ship Ebisu-4D to Magnus. +09:39 < geertu> Shimoda-san says the Renesas Vietnam test team will test 4.14-ltsi-rc1 when +09:39 < geertu> released. +09:39 < geertu> Geert will continue QEMU GPIO virtualization, handle SYSC and PFC errata, +09:39 < geertu> and test 4.14-ltsi-rc1 when released. +09:40 < geertu> C) Problems we have currently: +09:40 < geertu> Morimoto-san wants the team to start using periject from October, but +09:40 < geertu> Magnus/Laurent haven't accepted it yet. +09:40 < geertu> Niklas is looking for a solution to control the SDn/SDnH clocks properly. +09:40 < geertu> Greg is too busy with normal stable updates, but promised to release +09:40 < geertu> 4.14-ltsi-rc1 this week. +09:40 < geertu> --- +09:40 < geertu> Anything I missed? +09:41 < pinchartl> geertu: do you want to discuss the periject topic ? +09:41 < geertu> pinchartl: Yes ;-) But let's do the technical one first? +09:42 < geertu> Topic 2. Discussion Topics +09:42 < geertu> A) SDn/SDnH clocks +09:42 < pinchartl> geertu: sure, I just wanted to know whether I should prepare myself mentally :-) +09:42 < geertu> pinchartl: Fetch the booze ;-) +09:42 < horms> What are the LTSI-4.14 backporting implications of the patch that Shimoda-san posted? +09:42 < geertu> horms: Which patch? +09:43 < geertu> USB2 properties? +09:43 < horms> Yes +09:44 < horms> Reading the above for a second time, perhaps LTSI and the USB2 properties patch are only related by virtue of being handled by Shimoda-san +09:44 < wsa_> neg: you there? +09:45 < neg> wsa_: yes +09:45 < shimoda> geertu: horms: usb2 properties patche is for mainline first, not LTSI only +09:45 < shimoda> s/patche/patch/ +09:45 < horms> ok +09:45 < wsa_> neg: before I forget, HS400 on H3 ES1.0 is considered broken and we do not support it +09:45 < geertu> horms: USB2 properties come with DT binding updates, driver updates. +09:45 < wsa_> there should be a patch in the BSP for that, too +09:46 < neg> wsa_: OK good to know, will reduce the number of tests needed :-) +09:46 < horms> geertu: unerstood. I now recall the patches in question. I guess that means its not suitable for LTSI-4.14 at this point. But we can discuss if desired +09:46 < geertu> Some parts I don't fully grasp yet. And some additional clocks are not documented in the DT bindings? +09:46 < geertu> horms: Indeed. TBD when fully accepted. +09:46 < neg> wsa_: Then the clock issue only effects H3 ES2.0 and M3-W ES1.* +09:47 < wsa_> neg: right, the 4tap ones +09:47 < geertu> One issue is the SDnH clocks are referred nowhere. +09:47 < shimoda> horms: i agree this usb2 properties patch is not suitable for the LTSI +09:47 < geertu> Which is due to MSTP clocks being a single clock, while the "module stop" operation may apply to multiple clock signals provided to the module. +09:48 < shimoda> geertu: i posted https://patchwork.kernel.org/patch/10589889/ , but not enough? (especially host and phy?) +09:48 < wsa_> so, the problem with the SDHI clocks is that we want to request 200MHz for HS400 which needs different setting that 200MHz for SDR104 depending if we have a 4tap SoC or 8tap SoC, right? +09:50 < neg> wsa_: I have not looked at what setting SDR104 needs, but for HS400 on 4tap we need a different setting then on 8tap +09:50 < geertu> neg: 4tap or 8tap is a property of the SoC, not of the SDHI mode? +09:51 < geertu> shimoda: What about the added clocks to the ehci/ohci nodes? +09:51 < neg> geertu: yes 4tap = H3 ES1.* (broken no concern) ES2.0 and M3-W ES1.* +09:51 < wsa_> if you mean HS400 etc as "SDHI mode", then yes, it is a property of the SoC +09:51 < geertu> OK, so soc_device_match() can do? +09:52 < wsa_> neg: please take SDR104 into account as well, we need a complete solution +09:52 < geertu> I thought the clock settings depends on the HSx/SDRx mode, too, which the clock driver cannot lnow about. +09:52 < geertu> s/lnow/know/ +09:52 < neg> wsa_: will do +09:53 < wsa_> the 4tap need a different setting for 200MHz depending on SDR104 or HS400 +09:53 < wsa_> the BSP solves this by requesting 400MHz +09:53 < geertu> So the clock settings purely depend on (A) requested clock rate from SDHI driver and (B) SoC model and revision? +09:53 < wsa_> which looks as a workaround to me +09:54 < wsa_> clock rate, mode (SDR or HS), SoC revision +09:55 < wsa_> model & revision +09:55 < shimoda> geertu: for now, gen3 ehci/ohci is related to usb/usb-ehci.txt. But, should I add ehci-rcar for instance? Or, revise usb-ehci.txt somehow? +09:56 < geertu> wsa_: And the clock driver only knows clock rate and SoC revision, it doesn't know about SDR or HS, right? +09:56 < wsa_> yes +09:56 < wsa_> I wonder if exposing SDnH is the proper solution +09:57 < geertu> I was just going to ask about that... +09:57 < geertu> I don't fully understand the cpg_sd_div_table[] +09:57 < wsa_> Then, the driver can handle both clocks individually +09:57 < geertu> What's the physical clock difference between HS200 and HS400? +09:57 < wsa_> we need to take care of backward compatibility then +09:57 < Marex> geertu: SDR vs DDR +09:58 < wsa_> geertu: 0. It is DDR +09:58 < Marex> geertu: the bus runs at 200 MHz in both cases +09:58 < geertu> Marex: I mean the SDn and SDnH clock rates +09:59 < neg> for backward compability as SDnH is the parent of SDn can't we leave DT as is and have the driver get the parent of SDn (which it have access to today) and than control it's rate? +09:59 < Marex> geertu: they do differ, depends on SoC and revision, which is documented in the SDHI addendum +09:59 < geertu> shimoda: ehci/ohci DT bindings are very vague about clocks. I think adding an R-Car section may help. +09:59 < Marex> geertu: it's almost at the end of that document +10:00 < wsa_> neg: that might work. leaving dt as is would be much preferred +10:01 < geertu> Marex: Thx. So SDn=200 MHz, while SDnH=400 or 800 MHz +10:01 < wsa_> yup +10:02 < geertu> And the SD-IF module clock is based on SDn, while we could change that in the kernel to SDnH. +10:02 < shimoda> geertu: "adding an R-Car section" means into usb-ehci.txt? Or, as a new file? +10:02 < geertu> shimoda: Documentation/devicetree/bindings/usb/usb-ohci.txt and Documentation/devicetree/bindings/usb/usb-ehci.txt +10:03 < shimoda> geertu: Thanks! I'll add it. +10:04 < geertu> neg: You still need some heuristic to know if the Sdn divider is /2 or /4, right? +10:05 < neg> geertu: not following you +10:05 < geertu> Is there some table available listening all modes and according clocks rates? +10:06 < geertu> neg: If the driver request SDnH = 800 Mhz, it should program SDn to SDnH / 4 +10:06 < geertu> neg: If the driver request SDnH = 400 Mhz, it should program SDn to SDnH / 2 +10:07 < neg> geertu: yes, but if we expose SDnH as the parent clock of SDn the driver can control them both "independently" right? +10:07 < geertu> driver = clock driver or sdhi driver? +10:07 < neg> driver = sdhi +10:08 < neg> geertu: so first setting SDnH=800Mhz or 400Mhz and then SDn = 200Mhz would do the "right" thing? +10:08 < geertu> If the sdhi driver needs to see both, you have to update DT +10:08 < geertu> which may not be that unlogical ;-) +10:08 < neg> geertu: why can't I in the sdhi driver get the parent clock of SDn which is described in DT today? +10:10 < geertu> neg: DT describes SD-IFn, it's parent is SDn +10:11 < neg> geertu: ahh +10:11 < geertu> SDn's parent is SDSRC 9currently). +10:11 < geertu> You want to change that to SDSRC -> SDnH -> SDn -> SD-IFn. +10:12 < geertu> So the sdhi driver would get the parent of the parent of its clock, and modify that? +10:13 < neg> it would work but don't feel right :-) +10:13 < geertu> That's doable (clk_get_parent), but we need to modify all clock drivers at once. +10:13 < geertu> Exactly. +10:13 < wsa_> isn't SDnH derived from SDSRC as well? (don't have a datasheet handy at the moment) +10:13 < geertu> What about adding the SDnH clock to the clocks property of the SDHI nodes? +10:14 < wsa_> we could make HS400 dependent on the availability of this second clock +10:14 < wsa_> we haven't enabled it yet, so no regressions +10:14 < geertu> Yes, both are derived from SDSRC +10:14 < geertu> Exactly my thought. +10:15 < geertu> SDSRC -> 1/{1,2,4,8,16} -> SDnH -> 1/{2,4} -> SDn +10:15 < geertu> And we model (in the clock driver) SDn -> SD-IF +10:16 < geertu> Alternatively, we can model (in the clock driver) SDnH -> SD-IF, and use a heuristic (in the clock driver) to set the rate of SDn based on SDnH +10:16 < geertu> But before we do that, I'd like to see the full table of all modes and clock rates. +10:17 < geertu> What about impact on Gen2? +10:18 * geertu realizes we're running into the MM meeting time (and pinchartl is trembling) +10:18 < wsa_> Gen2 has no HS400 +10:18 < wsa_> it has SDR104, though +10:18 < geertu> But it does have SDnH, which we don't model. +10:19 < pinchartl> geertu: if we want to discuss periject, that's core time ;-) +10:19 < pinchartl> (I'm not requesting that topic to be discussed, I was just enquiring) +10:19 < neg> seems like SDH and SDn have fixed freq on Gen2, but I just looked at the blockdiagram +10:21 < neg> To not spend anymore time on this topic it seems we have concensus that SDnH should be exposed on Gen3? So that will be the first step and I'm happy to have a direction for now :-) +10:22 < geertu> neg: Not according to SDCKCR, which controls SDH, SD0, and SD1 +10:22 < geertu> Ugh, they share SDH for SD0 and SD1 on H2 +10:22 < geertu> Let's move on to +10:23 < geertu> B) Periject +10:23 < wsa_> neg: yes, i think that direction looks worthwhile +10:25 < geertu> Do we have (silent) Magnus in the house? +10:25 < damm> yep +10:26 < pinchartl> mostly silent Laurent is here too +10:26 < pinchartl> damm: have you had a chance to discuss the process internally with Renesas ? +10:26 < geertu> Let's start speaking up ;-) +10:26 < damm> nope, i thought you wanted to finalize stuff internally first =) +10:27 < damm> in general i like your approach last meeting, but there were some loose ends i think +10:27 < damm> jacopo had some ideas +10:28 < pinchartl> damm: +10:28 < pinchartl> 11:05 < pinchartl> depending on the result of the internal discussions, I'll try to propose a format +10:28 < pinchartl> 11:06 < pinchartl> can that be our conclusion for today ? +10:28 < pinchartl> (from last meeting) +10:28 < pinchartl> 11:07 < damm> seems all good to me at least +10:28 < pinchartl> 11:01 < pinchartl> damm: would you like to take this internally and report the result of the discussions in the next meeting ? (or possibly before) +10:28 < pinchartl> (out of order, sorry) +10:28 < pinchartl> I thought internally meant inside Renesas +10:28 < damm> then we have a misunderstanding =) +10:28 < damm> i thought you were going to go over it once internally in our group =) +10:29 < pinchartl> 10:48 < damm> i think i should have a q&a with the renesas folks using the chat log until next time if someone could include the chat log in the report +10:29 < pinchartl> that's what I meant by internally -_-' +10:29 < damm> ok sorry, i have not done that +10:29 < damm> gotcha +10:29 < pinchartl> if we both wait for each other, lack of progress isn't surprising :-) +10:29 < damm> so no update from me, but i'll add it to my calendar +10:29 < damm> what's the plan with the opinion from jacopo? +10:29 < pinchartl> thanks +10:30 < pinchartl> which opinion ? +10:31 < damm> i recall he voiced his opinion (some ideas about the process) but we ran out of time +10:31 < damm> did you hear anything from him? +10:32 < damm> i did not. if neither one of us heard anything more then lets igore it to keep things simple +10:32 < pinchartl> I haven't +10:32 < pinchartl> jmondi: do you remember what your opinion was ? :-) +10:32 < jmondi> pinchartl: sort of :) +10:33 < jmondi> I basically asked for BSP to use $TOOL to clearly describe issues/features they try to solve, and then consider the patch series +10:33 < jmondi> not the other way around... +10:34 < jmondi> but there was quite a bit of push back, because BSP team do not want this burden, because, well, they do not care much about upstreaming +10:34 < jmondi> that's it +10:36 < pinchartl> I do agree that we need more information from the BSP team in many cases as commit messages are very terse +10:39 < pinchartl> that seems to be it for today ? +10:39 < damm> ok, so can we proceed with the process as-is as described by laurent? +10:39 < pinchartl> no issue on my side +10:39 < damm> i will check with renesas side and get back to you next meeting +10:39 < pinchartl> (I fortunately agree with my own proposal :-)) +10:40 < damm> hehe +10:40 < pinchartl> damm: would you have time for a quick HO discussion after this meeting ? +10:40 < jmondi> damm: me too +10:40 < jmondi> :) +10:41 < wsa_> HO? +10:41 < damm> sure, just connect to me +10:41 < pinchartl> HO=hangout +10:42 < geertu> wsa_: https://www.urbandictionary.com/tags.php?tag=ho +10:42 < pinchartl> geertu: the mic is now yours to finish the core meeting +10:43 < geertu> Thanks ;-) +10:43 < geertu> Next meeting date?

Might be worth some feedback to the HW team? +09:13 < Marex> wsa_: since it's a transient fault, it might just make sense to trap the SError in ATF and restart the instruction +09:14 < geertu> Marex: So the issue happens when the arm64 core accesses the PCIe bus while a device sent a link status change? +09:14 < Marex> wsa_: what happens is that <someone> may start transitioning the PCIe device to lower power state (think D3hot for simplicity) ... at one point, the device sends PM_Enter_L1 DLLP to the controller +09:15 < geertu> And that's where "restart the instruction" comes into the picture? +09:15 < Marex> that one triggers automatic PLL shutdown in the PCIe controller, but does not completely transition the link to L1 state from the PCIe controller side +09:15 < Marex> at that point, you cannot trigger config accesses to the card anymore, it will trigger those SErrors +09:15 < Marex> the software must at that point poke the controller PMCTRL register bit to finish the transition to L1 state +09:16 < Marex> once that happens, everything is great again and you can do config accesses ; the config access will recover the link to L0 state etc etc +09:17 < Marex> the problem is, IFF ie. a user decides to send config access with ie. setpci just at the right (or wrong?) time between the controller receiving PM_Enter_L1 DLLP from the card and the PMCTRL poke, the system crashes with unhandled SError +09:17 < Marex> and I think it might just be possible to trap that SError in ATF and restart the instruction which caused it (it's a single register write, so that should be fine) +09:17 < geertu> Thanks for explaining. I was always wondering where the instruction restart fit in the picture. +09:18 < geertu> As long as it's not an imprecise external abort, you're fine ;-) +09:18 < Marex> now there's another funky thing, but that's probably kinda ... hypothetical +09:18 < Marex> IFF someone does config access from an interrupt handler , the CPU gets async SError and that's sort of the end +09:19 < wsa_> horms: when could you start working on the 4byte RAVB alignment patch? I think ASAP would be cool, before LTSI becomes super big again? Does that make sense? +09:19 < Marex> geertu: the async serror is a problem too ^ +09:19 < Marex> geertu: I still need to verify if this cannot happen outside of interrupt context somehow too +09:19 < horms> wsa_: ASAP is fine :) +09:19 < wsa_> horms: great! +09:20 < wsa_> Marex: do the HW guys know the controller should do the L1 link properly on PLL shutdown? +09:20 < wsa_> is it a known errata? +09:20 < geertu> wsa_: Doesn't commit d38d4fc29e8cd71b ("PCI: rcar: Add compatible string for r8a77990") need actual testing? E.g. Magnus inserts PCIe card in Ebisu, and Marex dooms it? +09:21 < Marex> wsa_: it should do it automatically, I don't know why they decided to require this register poke +09:21 < shimoda> Marex: I'm not sure but, can we avoid to send PM_Enter_L1 DLLP from the card somehow? +09:21 < wsa_> Marex: that's what we need to discuss IMHO +09:21 < Marex> shimoda: I was thinking about the same, but the user can just use setpci to bypass it +09:22 < Marex> shimoda: user can use setpci to set PM_CAP+4 register on the card or maybe some other funny register which is implementation defined by the card and that'd be it +09:23 < Marex> wsa_: that's what needs to be fixed in the next generation of hardware I think +09:23 < wsa_> Marex: I agree. That's why I want to make sure HW people are aware there is a problem +09:23 < Marex> geertu: my question would rather be, why do we need another compatible which is not in the compat table of the controller driver ? Is the PCIe different on ebisu somehow ? maybe like the i2c ? +09:24 < wsa_> it is just for DTS verification +09:24 < Marex> wsa_: it's probably better to explicitly state it one more time then +09:24 < geertu> Marex: We don't know. We may find out only later, so that's why we need the SoC-specific compaible values. +09:25 < Marex> wsa_: but then. aren't we missing also 77980 and 77970 entries ? +09:25 < wsa_> we want specific compatibles before the generic fallbacks just in case +09:25 < wsa_> Marex: you can add them if you want +09:25 < Marex> jupp, fine +09:25 < wsa_> but usually, those SoCs are upstreamed by Cogent +09:26 < Marex> shimoda: so do you think the HW team would be willing to fix this L1 transition issue in next HW cycle ? +09:27 < Marex> shimoda: or could they maybe add a bit which says "do L1 transition automatically and if someone does config access during transition, stall the bus until transition completes" ? +09:27 < wsa_> geertu: shall I update the MSIOF entries in periupport, or can you do it when you update core items? +09:28 < Marex> wsa_: OK, the patch ^ is picked +09:28 < geertu> wsa_: I will update them with the proper commit ID (broonie is fast) +09:28 < shimoda> Marex: I don't know. But, I should ask them for next hw. +09:29 < wsa_> geertu: thanks! +09:29 < wsa_> are there any questions from your side? +09:29 < wsa_> I'd guess neg's question about SDHI clocks could also be discussed in the core meeting? +09:30 < geertu> yes +09:31 < horms> I'd like to ask about coordinating / requests for upporting tasks for Kaneko-san. +09:32 < horms> But perhaps that is best done in Core or elsewhere +09:32 < wsa_> uli___: any news on the SCIF suspend/resume patches? +09:32 < geertu> horms: Sorry for stepping on Kaneko-san's toes. +09:32 < Marex> shimoda: yes please ! :) +09:32 < geertu> But MSIOF is something you need to test with HW access. +09:33 < horms> It happens, don't worry about it +09:33 < uli___> wsa_: no, not yet +09:34 < wsa_> uli___: any specific problems with it? or just too many tasks? +09:34 < geertu> horms: Does Kaneko-san has access to periupport? +09:34 < Marex> shimoda: I still have to wonder why they decided to insert this bit into PMCTRL and effectivelly stall the L1 enter state machine, all the controllers I know just do the transition fully automatically +09:34 < uli___> wsa_: stuff unrelated to work lowered my productivity severely... +09:34 < geertu> horms: "arm64: dts: r8a77995-draak: Add MSIOF ch2 pins support" is marked "Proposing 'N': MSIOF2 is unused on the Draak board"? +09:35 < wsa_> uli___: oh, didn't know that.

And we discuss about it at ELCE end of October? +09:55 < wsa> or did i get something wrong? +09:55 < horms> Is there also a dialog in progress regarding the value/role of the upstream team? +09:57 < damm> wsa: i want the plan to point out clarly which tool to use when +09:57 < damm> wsa: if you have any preference feel free to share that +09:57 < wsa> horms: I wonder about that, too. Especially since there I know of some good example recently where our good connections with upstream saved us some work (SCCB rework, irqless I2C transactions, DMA 32bit limitation) +09:58 < damm> horms: not yet +09:58 < pinchartl> damm: that's a very vague question... +09:58 < damm> horms: at this point it is just focusing on the interface/format for the up port work +09:58 < damm> so about "the tool" +09:59 < horms> damm: feel free to drag me into any conversation if you think I can be of assistance +09:59 < horms> But lets get back to the process/tool discussion - sorry for the noise +09:59 < damm> horms: thanks +09:59 < damm> np +09:59 < damm> so the way the tool was developed and the expected process order from my (and pinchartl) seems to mismatchhhh +10:00 < damm> so rolling in the tool urgently w/o a clear process seems rusing in the potentially wrong direction +10:00 < wsa> damm: I am fine with your plan to point that out clearly. I just was confused about the dates +10:00 < damm> ok +10:00 < pinchartl> from my side the problem is clear. I can't comment on tooling if I'm not told what the process is, in *details* +10:00 < damm> i want to clarify the expectation from each side +10:01 < pinchartl> (to use an analogy everybody here should be able to understand, I can't review an implementation if I'm not told what API it implements) +10:01 < damm> maybe we will see that we have different expectations =) +10:01 < damm> pinchartl: i'm with you +10:02 < damm> i want to help clarify expectation from renesas side first +10:02 < damm> then let you guys hash it out during ELCE +10:02 < wsa> damm: same as horms, I'd like to be assistance for that discussion if you think I could be useful. (and now back to "the tool") +10:02 < damm> while i am in hiding some place else +10:03 < damm> wsa: so you should join pinchartl for the process discussion topic +10:04 < damm> so i expect you guys to take the plan from renesas side and request minor updates or ask for major change with your own proposal if needed +10:04 < damm> this to make sure we have a healthy discussion +10:04 < damm> just accepting won't help anyone +10:04 < wsa> damm: you mean at ELCE, sure thing +10:05 < damm> (i don't expect that from pinchartl) =) +10:05 < damm> wsa: yep +10:05 < damm> is my expecation about this far ooff? +10:06 < damm> (thats how it gets when you live in your PJs most of the time) +10:06 < pinchartl> damm: if you expect me to make a major counter proposal, I may be able to live up to your expectations :-) +10:06 < damm> haha +10:06 < damm> i hope to give you some clear expectation to work with +10:07 < damm> perhaps you can adjust timing of tool change etc +10:07 < damm> depending on how much time you expect is needed for the process discussion +10:08 < damm> so let me report back next chat meeting about the plan so far +10:09 < pinchartl> sounds good to me +10:09 < damm> any questions that i ducked? +10:09 < damm> or new ones? +10:10 < damm> pinchartl: do you have any expected frequency of broken out process discussions? +10:10 < damm> for next 6 months +10:11 < pinchartl> damm: not really. ideally we'll have one good discussion, decide on a plan, and move forward +10:12 < damm> then do your best at ELCE timing and we can take minor increments from there? +10:12 < damm> shall we do one more process discussion meeting via HO or similar before ELCE? +10:13 < damm> maybe we can ponder a bit for now and book something next chat meeting? +10:13 < pinchartl> I think you know my position. if there's more information to share, we can have another discussion, otherwise I don't think it would be very useful +10:14 < damm> we will have some info in form of a plan next meeting +10:15 < damm> my point is that when we discussed last time we only got to touch part of the subject +10:15 < damm> but anyway +10:15 < damm> no questions?

+10:47 < damm> nope +10:47 * morimoto I believe I can get some answer about 3 questions +10:47 * morimoto in later +10:48 < pinchartl> morimoto: I've seen them, we'll get to that, don't worry :-) +10:48 < pinchartl> so regarding additional tasks for Q4 +10:48 < morimoto> thanks +10:48 < pinchartl> we have reduced budget +10:48 < pinchartl> which implies reduced additional tasks +10:49 < pinchartl> with 10 days per quarter I don't see how we can reasonably include upstreaming in any additional task anymore +10:49 < pinchartl> damm: I would thus like to know what type of tasks Renesas will expect now +10:49 < pinchartl> they just can't include everything from development to upstreaming anymore +10:50 < pinchartl> upstreaming will need to be handled under base time +10:50 < damm> pinchartl: yes i agree +10:51 < jmondi> which makes, depending on how much time one has left, only one task in total for q4 per person acceptable +10:51 < pinchartl> jmondi: I would go for one task per quarter, yes +10:51 < jmondi> as it will consume additional time for implementation and all base time for upstreaming +10:52 < jmondi> pinchartl: yeah, my point is that also base time will be affected, leaving not much time for the usual base tasks (review, backlog, etc) +10:53 < jmondi> but I think this a well known issue... +10:53 < pinchartl> it should be known at least +10:53 < pinchartl> it's certainly known on our side that less time means less output :-) +10:54 < pinchartl> damm: you explained before that Renesas expected upstreaming to be included in additional tasks. now that this can't be done anymore, what type of tasks would be acceptable ? +10:58 < damm> prototypes, minor bug fixes, building some hardware rig to extend testing etc +10:58 < pinchartl> ok, thanks +10:58 < damm> makign test programs +10:58 < damm> or extending them +10:58 < pinchartl> so we need to come up with additional tasks +10:58 < damm> that's my take at least +10:58 < pinchartl> I would like all multimedia developers to submit proposals +10:59 < pinchartl> you can reply to the meeting report e-mail, or we can discuss them now if you already have ideas +10:59 < kbingham> pinchartl, I'd probably consider the M3-N Rotation bug as a candidate then +11:00 < jmondi> there are a few things around adv748x but I'm not sure how to assign them +11:00 < neg> I would love to work on improving test rigs but is that not a dangerus path to prove the value of the upstream team? +11:00 < neg> Would it not be a bit more clever to package a set of IP specific upport commits as add tasks? +11:01 < pinchartl> neg: my understanding is that upport as an additional task was frowned upon by Renesas, but things might have changed +11:02 < neg> pinchartl: ahh I see was not aware of that scrap that then :-) +11:02 < damm> actually +11:02 < damm> i don't mind including the up-port bit +11:02 < damm> if it is something that can be defined clearly and is in demand +11:02 < pinchartl> damm: that's good to hear :-) +11:02 < damm> also about test rig +11:03 < damm> if we can document how things may be done in a public space then i think it has value by itself +11:04 < damm> (this is how we automate eject/insert of SD cards for example) +11:04 < kbingham> There is an automated-testing mailinglist (I think started by Tim Bird) where lots of farming talks are currently occuring in public space. +11:04 < kbingham> And a test-summit at ELCE +11:04 < kbingham> geertu, Are you attendign that test summit? +11:04 < pinchartl> the testing summit will occur at the same time as the V4L2 summit I believe :-( +11:05 < geertu> kbingham: yes I will. Will mostly be about the automated testing part, I believe +11:05 < kbingham> geertu, I'm sure that's what we need more of :) +11:06 < geertu> pinchartl: Yes, -ETOOMANYCONCURRENCY +11:06 < pinchartl> geertu: something like that +11:06 < geertu> kbingham: Not if it involves Jenkins +11:06 < kbingham> geertu, Is that their only solution ? :S +11:08 < pinchartl> let's move to the next topic +11:08 < pinchartl> morimoto: you had questions +11:08 < morimoto> yeah +11:08 < pinchartl> I've just replied to them by e-mail +11:08 < pinchartl> I'll paste my replies here +11:08 < morimoto> I got answer from kbingham and jacopo +11:09 < neg> kbingham: well is not gerrit + jenkins the silver bullet solution to all software quality and assurence it be devliverd on time? +11:09 < morimoto> thanks ! I got your answer +11:09 < pinchartl> ah, there are other answers too +11:10 < pinchartl> regarding the VSP 1x1 image size, Mauro has applied to the patch to this tree +11:10 < pinchartl> s/this tree/his tree/ +11:11 < kbingham> Oh - I missed that :) +11:11 < kbingham> But great :) +11:11 < pinchartl> for the DU reserved registers, Jacopo has submitted patches +11:12 < pinchartl> but I'm concerned about all the changes that are requested to match the datasheet to the last detail, when there's no clear indication that this is needed +11:13 < pinchartl> I can consider merging Jacopo's series this time, but next time we'll get a request along the lines of "the datasheets states this order of operations, the driver need to match" I will request a proof that the current implementation causes a real bug +11:14 < wsa> damm: about remote inserting SD cards: I got a device from Pengutronix which does that +11:14 < pinchartl> and regarding the D3/E3 LVDS PLL and clock issue, I plan to submit that as an additional task for Q4 +11:14 < pinchartl> morimoto: does this answer your questions ? +11:14 < damm> wsa: great! i recall linaro had something like that too +11:14 < jmondi> pinchartl: awmm (I don't know how to properly express demotivating feelings with onomatopoeic expressions in English, hope it's clear) +11:15 < pinchartl> jmondi: it's not a judgment on the quality of your work, but I think that several requests we have received are pointless to start with +11:15 < wsa> damm: https://www.pengutronix.de/2017-10-23-usb-sd-mux-automated-sd-card-juggler.html +11:15 < pinchartl> and I don't want to continue increasing the complexity of an already complex piece of code when there's no need to +11:15 < morimoto> pinchartl: sorry my late response. Thanks, nice answer +11:15 < damm> pinchartl: since many devices are shared IP that should work on many SoCs it would make sense to give feedback to renesas to make sure the register read/write order is consistent across products +11:16 < morimoto> I will forward these to BSP team +11:16 < jmondi> pinchartl: sure I get it, I was referring to this kind of requests +11:16 < pinchartl> damm: it's not just about consistency between products, it's also that in many cases a specific write order is not required +11:17 < pinchartl> if you have to program lots of registers before starting the hardwarer +11:17 < pinchartl> more often than not the order doesn't matter +11:17 < damm> lets just say that i agree with you very much +11:17 < wsa> I could ask if they can bring some to ELCE if that helps. I can bring the one I have, too +11:17 < pinchartl> and mandating a specific order sometimes creates extra complexity in the driver by breaking the natural grouping of parameters we get from existing APIs +11:18 < damm> i'm with you +11:18 < pinchartl> thanks :-) +11:18 < damm> that kind of request makes the "alpabetize the headers" thing look good +11:18 < morimoto> pinchartl: sometimes (anytimes ?) BSP team cares very picky point +11:19 < pinchartl> damm: :-D +11:19 < pinchartl> morimoto: in many cases they have good points, they point us to small bugs that are hard to find or only happen in some corner cases, but that are bugs nevertheless, and I'm happy to fix them +11:20 < pinchartl> but sometimes it really feels like they have been asked to do something and they push the request down to us, even if the request wasn't very sensible to start with +11:20 < damm> if there are dependenices and ordering between several IPs it would be helpful to know those ahead of time +11:20 < morimoto> one reason is that it is related to customer +11:21 < morimoto> customer is checking "datasheet" and "driver" +11:21 < pinchartl> morimoto: then I think the datasheet should be updated +11:21 < pinchartl> as that's where the problem is +11:21 < morimoto> and ask to us "why datasheet and driver are not same ?" if driver and datasheet are mismatched +11:21 < pinchartl> if the hardware can work with multiple orders +11:21 < pinchartl> and the datasheet says that a specific order is required +11:21 < pinchartl> then the datasheet is wrong :-) +11:22 < damm> the data sheet is like a recommendation +11:22 < damm> it is more like fiction than fact +11:22 < morimoto> yeah, sometimes multiple order is OK. but it is case-by-case +11:23 < morimoto> This is unfortunately complex area to solve +11:23 < pinchartl> of course when some operations have to be ordered a certain way, and the driver doesn't follow that, we should fix the code +11:23 < damm> morimoto: but changing order requirement late in the process seems not very useful +11:23 < morimoto> HW team vs datasheet team vs softweare team vs customer +11:23 < pinchartl> one problem with the datasheet documenting a particular order without stating whether it's mandatory or not, +11:24 < damm> morimoto: if this was a requirement then we want to know this from day 0 +11:24 < pinchartl> is that important information get lost in the noise +11:24 < pinchartl> as it then becomes easy to read the datasheet and think that it's just the usual case of a recommended order +11:24 < pinchartl> while it's actually super important +11:25 < pinchartl> so by saying that things are mandatory all around when they are not, the real mandatory ones don't clearly show +11:25 < pinchartl> but I don't think there's any fundamental disagreement among us here +11:25 < pinchartl> any other discussion topic ? +11:26 < damm> pinchartl: maybe we can implement some hardware abstraction layer and use the drivers from Integrity(tm) that follow the correct order(tm) +11:26 < morimoto> This kind of topic is unfortunately difficult to solve. I will ask to BSP team whether it is very important, or datasheet side can updated or so. +11:27 < damm> my opinion is that shared IP needs to be discussed on a broader scale +11:27 < damm> renesas needs to learn how to manage shared ip +11:28 < damm> i expect you guys to help out that process by good feedback =) +11:28 < damm> no other topic from me +11:28 < morimoto> I think this is not only Renesas issue. Many people are related to this kind of topic, but no one knows who has correct answer... +11:28 < morimoto> no topic from me, too +11:29 < jmondi> nothing to add from my side neither +11:29 < pinchartl> alright +11:29 < pinchartl> last topic then +11:29 < pinchartl> next meeting +11:29 < pinchartl> two weeks from now, on October the 4th, same time as usual ? +11:30 < kbingham> Aribtrary question from me - Has Gen4 hardware been started already ? +11:30 < morimoto> kbingham: not yet +11:30 < kbingham> ( I assume they start gen4 before Gen3 ships) +11:30 < kbingham> Oh ok - so my assumption is wrong ;) +11:30 < morimoto> it is depend on what is your "start" mean +11:31 < morimoto> "Gen4 plan" is started, "Gen4 implement" is not yet +11:31 < kbingham> :) +11:32 < kbingham> So it's 18-24 months at least or more before any g4 hardware appears then :) +11:32 < morimoto> But we will have Gen3.5 :) +11:32 < kbingham> Oh :) +11:32 < morimoto> I don't know detail, thought +11:32 < neg> Gen3.5 = new ES versions ? +11:33 < morimoto> neg: I don't know, sorry +11:33 < geertu> s/arm/risc-v/? +11:33 < neg> morimoto: no worries just curious :-) +11:33 < morimoto> geertu: not Risc-V :) +11:34 < kbingham> pinchartl, Oct 4th sounds good to me. +11:34 < morimoto> Oct 4th is OK to me +11:35 < pinchartl> that's all I have for today +11:35 < neg> 4th OK for me +11:35 < pinchartl> I propose adjourning the meeting +11:35 < pinchartl> does anyone second ? +11:36 < jmondi> fine wiht me +11:36 < neg> seconded, thanks for hosting the meeting +11:36 < morimoto> 2nd +11:36 < pinchartl> meeting adjourned, thank you all for attending, and have a nice day ! diff --git a/wiki/Chat_log/20181004-core-chatlog b/wiki/Chat_log/20181004-core-chatlog new file mode 100644 index 0000000..135a15d --- /dev/null +++ b/wiki/Chat_log/20181004-core-chatlog @@ -0,0 +1,111 @@ +Core-chat-meeting-2018-10-04 + +09:35 < geertu> Welcome to Today's Core Group Chat! +09:35 < geertu> Agenda: +09:35 < geertu> 1.

He will discuss with Simon-san about R-Car E3 enablement. +09:36 < geertu> Geert will sent a third pinctrl pull-request for v4.20, Remove +09:36 < geertu> SoC-specific ARCH_* symbols to please arm-soc, and handle SYSC and PFC +09:36 < geertu> errata. +09:38 < geertu> Anything I missed? +09:38 < horms> geertu: I'd like to talk about those symbols and how to finalise getting our v4.20 patches accepted. But it can be outside of this meeting. +09:40 < geertu> OK, let me summarize +09:40 < geertu> Arnd asked to remove all SoC-specific ARCH_* symbols, as other vendors don't have them. +09:40 < geertu> However, this means the SoC-specific CLK_* and SH_PFC_* symbols will become user-visible. +09:41 < geertu> In addition, there are a few other places (mostly drivers/soc/renesas/) where these ARCH_* symbols are used, so they have to be "fixed". +09:42 < Marex> geertu: I wanna focus on U-Boot testing, but that's a detail +09:42 < geertu> We do want to avoid including too much unneeded stuff where it makes sense (e.g. RZ/A with internal SRAM only and XIP) +09:43 < geertu> horms: Any comments? +09:43 < horms> geertu: So I see we will need to make some adjustments. Will they be for both ARM and arm64? Once we have sorted out what they are, can we make sure everyone, including Chris Patterson, is aware so new patches follow the new way. I assume any changes will take effect in v4.21 at the earliest, in which case we can prod Arnd to take the existing pull request. +09:44 < geertu> horms: If we do it for arm64, I think it makes sense to do it for arm32, too. +09:44 < horms> It seems to me that Arnd has a policy that he wishes to enforce - for no other reason than it exists. Iguess we have to work with that. +09:44 < horms> Ok, consistency is good for me. +09:45 < horms> Is the plan to expose the CLK_* and SH_PFC_* symbols? +09:45 < horms> It doesn't seem terrible to me +09:45 < horms> Though it does seem slightly worse than the current situation +09:45 < geertu> We will need a new ARCH_RCAR_GEN3 symbol, as ARCH_RENESAS applies to arm64 and arm32, and Arnd was OK with that +09:46 < geertu> Correct, CLK_* and SH_PFC_* symbols will become user-visible (they already were for RZ/A1 and RZ/N1, as they may rely on the bootloader for pinctrl setup, to reduce kernel size) +09:46 < horms> Ok, I'm a little confused about the purpose of ARCH_RCAR_GEN3 +09:47 < wsa_> ARCH_RENESAS64? +09:47 < horms> I assume it would cover RZ/G2 but not some other SoCs, say RZ/A2 +09:47 < geertu> Correct. +09:47 < geertu> RZ/A2 is arm32, so not affected +09:47 < horms> Would it be user-visible? +09:48 < geertu> drivers/soc/renesas/Kconfig +09:48 < geertu> select RST_RCAR if ARCH_RCAR_GEN1 || ARCH_RCAR_GEN2 || \ +09:48 < geertu> ARCH_R8A774A1 || ARCH_R8A774C0 || ARCH_R8A7795 || \ +09:48 < geertu> ARCH_R8A7796 || ARCH_R8A77965 || ARCH_R8A77970 || \ +09:48 < geertu> ARCH_R8A77980 || ARCH_R8A77990 || ARCH_R8A77995 +09:48 < geertu> The last part would be replaced by ARCH_RCAR_GEN3 +09:49 < geertu> Oh, we also have SYSC_*, forgot about those... +09:49 < geertu> But the sysc files are smaller, so we could always include them, based on SoC family. +09:50 < geertu> ARCH_RCAR_GEN3 would not be user-visible +09:50 < geertu> For now, once e.g. RZ/A3 becomes arm64, we need a new family selector. +09:50 < horms> Ok, so we would end up with the same amount or rst code compiled in +09:50 < horms> More sysc code, but it would be onl a little bit more +09:50 < horms> And pinctl and clk would be selected by the user +09:51 < geertu> Correct. +09:51 < horms> Ok, I understand +09:51 < geertu> pinctrl code for one SoC is O(tens of KiB) +09:51 -!- neg [~neg@unaffiliated/neg] has quit [Read error: Connection reset by peer] +09:51 < geertu> clock code for one SoC is O(some KiB) +09:51 < horms> This does seem slightly worse than the current situation.

He received an RSKRZA1 board, and has started digesting SYSC +09:53 < geertu> errata. +09:54 < morimoto> Marek: from BSP 3.8.0 (= next BSP), it will use U-Boot 2018.09 +09:54 < geertu> B) What we plan to do till next time: +09:54 < geertu> Kaneko-san will follow up on D3 Thermal support, and plans to enable +09:54 < geertu> E3 PMIC support. +09:54 < geertu> Marek will enjoy ELCE, PeriPeriCon, and the SDHI hackfest, and will +09:54 < geertu> continue discussing FCNL. +09:54 < geertu> Morimoto-san will finalize the process images, explain and discuss +09:54 < geertu> processes in Edinburgh, and confirm BSP review results to the BSP team. +09:54 < geertu> Shimoda-san will review the new IPMMU driver's plan, and says the RCV +09:54 < geertu> test team will continue testing LTSI v4.14 until Oct 24th. +09:54 < geertu> Simon will follow up on D3 thermal support, and update periupport +09:54 < geertu> updates using "make patch". +09:54 < geertu> Geert will attend ELC-E and the Automated Testing Summit, enjoy autumn +09:54 < geertu> holidays, and plans to continue digesting SYSC and PFC errata. +09:55 < geertu> C) Problems we have currently: +09:55 < geertu> Marek wonders if 0x47fe0000 is a reasonable address for parameter +09:55 < geertu> passing from ATF to U-Boot, and where to submit patches for Renesas' +09:55 < geertu> ATF? +09:55 < geertu> Morimoto-san thinks Laurent has a plan to create a sample format for BSP +09:55 < geertu> commits. +09:55 < geertu> Geert discovered the stock kernel doesn't work on RSKRZA1 (reboots +09:55 < geertu> immediately). +09:56 < geertu> Anything I missed? +09:56 < Marex> morimoto: awesome :-) +09:56 < Marex> morimoto: do you know if renesas is satisfied with the current state of U-Boot ? +09:56 < pinchartl> Marex: should we discuss ATF+U-Boot+FCNL now ? +09:57 < Marex> pinchartl: it's MM topic +09:57 < geertu> Topic 2. Discussion Topics +09:57 < geertu> FCNL itself is MM +09:57 < geertu> ATF+U-Boot is core +09:57 < patersonc> morimoto: BSP v3.8.0 = internal Yocto v3.13.0 release right? +09:58 < pinchartl> Marex: it's in-between :-) +09:58 < geertu> A. PeriPeriEdi Agenda +09:59 < geertu> I'll follow wsa, for core: +09:59 < geertu> - Overview +09:59 < geertu> - High level "what happened since last f2f meeting" +09:59 < geertu> - Is the group happy +09:59 < morimoto> Marex: I think so :) +09:59 < morimoto> patersonc: sorry, I'm not sure BSP <-> Yocto relationship +09:59 < geertu> I was also thinking about a (short) virtualization status? +10:00 < Marex> morimoto: whew, OK, thank you +10:00 < patersonc> morimoto: No worries. Yocto v3.13.0 is the release due out e/Oct +10:00 < geertu> And of course Morimoto-san's graphics skills: +10:00 < geertu> - PeriPeri "process" explanation and discussion. +10:00 < geertu> - "upport process" +10:00 -!- wsa_ is now known as wsa +10:01 < morimoto> :) +10:02 < wsa> geertu: no updates for virt from my side :( +10:03 < geertu> wsa: I meant for the PeriperiEdi agenda ;-) +10:03 < geertu> You have a few more days to change that ;-) +10:03 < Marex> morimoto: looks like I have a few bsp u-boot patches to review :) +10:03 < wsa> geertu: yeah :D +10:03 < patersonc> Marex: So u-boot 2018.09 supports all R-Car Gen2/3 boards? +10:04 < geertu> Any other topics for the PeriPeriEdi agenda? +10:04 < morimoto> I asked it to BSP team now. It seems they are happy, but want to have more feature. They said that shimoda-san is interface guy for it? I was asked to bring SD card for you in ELCE +10:05 < Marex> geertu: all Gen3 and about half of Gen2 (the ones which I have access to) +10:05 < Marex> patersonc: ^ +10:05 < Marex> patersonc: I still need to sort out the rest of Gen2 +10:06 < geertu> B. ATF+U-Boot+FCNL +10:06 < Marex> patersonc: it should be trivial, given that I have a Silk, Porter and Stout , so E2, M2W, H2 +10:06 < Marex> patersonc: porting Koelsch, Lager, Alt should be boring +10:06 < Marex> patersonc: Blanche might be challenging due to it's PNOR boot +10:06 < patersonc> Marex: Great +10:07 < patersonc> Marex: Thank you for the update +10:07 < Marex> morimoto: which features do they want ? +10:08 < Marex> patersonc: I'll probably do it next time I'm in Japan and can grab a few boards from damm -san's farm +10:08 < morimoto> Marex: it seems shimoda-san / goda-san will (?) post mail to you +10:08 < Marex> morimoto: got it :) +10:08 < horms> pinchartl: I pushed an update to periupport +10:09 < morimoto> Marex: when is that ? +10:09 < Marex> morimoto: the only grueling item for me is HS200 , it takes a lot of boot time to calibrate :( +10:09 < geertu> Marex: Anything to discuss about ATF+U-Boot+FCNL? +10:09 < Marex> morimoto: I'd like it to be next year for the first Jamboree that's gonna happen +10:09 < Marex> geertu: well, ATF, is the 0x47fe0000 good address for the DT ? +10:09 < morimoto> Marex: OK, looking forward to see you then +10:10 < pinchartl> horms: thank you +10:10 < Marex> morimoto: :-) +10:10 < Marex> morimoto: I'll make sure to submit some talk +10:10 < geertu> Marex: Do all R-Car Gen3 SoCs/boards have memory there? +10:10 < Marex> yeah +10:10 < Marex> geertu: all we know about +10:11 < Marex> geertu: plus the FCNL tables are at 0x47fd7000 , so I didn't pick the address at random +10:12 < wsa> Marex: i can give you my lager + alt in edi for a few days before the SDHI hackfest ;) +10:12 < geertu> That's part of the "first 128MB is reserved for secure area", right? +10:12 < Marex> wsa: I have a talk at E-ALE-E and two at YPDD, so I dont think I'll have time +10:12 < pinchartl> Marex: how about replacing the FCNL tables completely +10:13 < Marex> pinchartl: ABI ? +10:13 < wsa> Marex: ok +10:13 < Marex> wsa: but maybe in Dunbar ? +10:13 < geertu> And no suitable space in ICRAM? +10:14 < pinchartl> Marex: there's no upstream user of that ABI. BSPs can always revert the removal +10:14 < wsa> Marex: you mean if we run out of SDHI topics ;))) +10:14 < Marex> wsa: heh +10:14 < Marex> pinchartl: we can have both, it costs us nothing +10:15 < Marex> maybe a few instructions, but it's probably easier for renesas +10:15 < wsa> Marex: j/k, sure the boards will be in Dunbar, too +10:15 < pinchartl> Marex: code bloat ? +10:15 < Marex> not really +10:15 < Marex> wsa: :) +10:16 < Marex> wsa: should be quick too, so maybe a lunch topic +10:16 < Marex> pinchartl: the tables are generated while the FDT is generated, so that's really not adding much +10:17 < pinchartl> Marex: I won't work on it myself, but given that it's a BSP ABI, we don't neeed to care about it +10:17 < Marex> pinchartl: the real question is, what is the purpose of those tables and who is the user of those tables ? +10:17 < pinchartl> that's my opinion at least +10:17 < geertu> Agreed +10:17 < pinchartl> there's no upstream user +10:17 < pinchartl> FCNL isn't supported upstream +10:17 < geertu> yet? +10:18 < pinchartl> even enabling FCNL in ATF right now with upstream U-Boot + Linux will lead to a certain death +10:19 < Marex> so there's more than just parsing the tables in U-Boot +10:19 < Marex> U-Boot itself must not relocate itself into those areas +10:19 < Marex> so that's another item to add to the list +10:20 < pinchartl> data will be difficult to parse if it's overwritten, indeed :-) +10:20 < Marex> can someone put FCNL at 0x47000000 + 0x01000000 ? +10:20 < Marex> if so, then the FCNL tables would be in FCNL and it's all over +10:21 < damm> pinchartl: any reason why we cannot use dynamic FCNL handling? +10:21 < geertu> ICRAM would be safer for that... +10:21 < pinchartl> damm: what do you mean by dynamic ? +10:22 < damm> i meant that we can program the memory ranges for decoding on the fly +10:22 < damm> instead of using fixed reserved areas +10:22 < pinchartl> the memory ranges are programmed in the DRAM controller registers, and that's only available in secure mode :-( +10:22 < geertu> If ATF programs the security engine to allow that +10:23 < Marex> geertu: could be a security issue +10:23 < damm> pinchartl: isn't that a LifeC configuration issue? +10:23 < Marex> but allocating the FCNL dynamically would be indeed nice +10:24 < damm> i always thought we could use physical mirror addresses for the compression purpose +10:24 < damm> and statically configure the mirror addresses for de-compression purpose +10:24 < pinchartl> sa +10:24 < damm> and then let the linux-side just fiddle some physical bit to enable decompression +10:24 < pinchartl> damm: can LifeC allow access to only part of the DRAM controller registers in non-secure mode ? +10:25 < damm> pinchartl: not sure +10:25 < pinchartl> compression is handled by the FCP +10:25 < pinchartl> only decompression is done on the fly by the DRAM controller +10:25 < pinchartl> (amazing design, if you ask me...) +10:25 < damm> so i don't think the memory controller needs to be dynamically configured +10:25 < damm> just the use of physical addresses in linux needs to be dynamic +10:26 < geertu> pinchartl: decompression is simpler, and needs less resources, than compression +10:26 < pinchartl> geertu: I would have put everything in the FCP +10:26 < pinchartl> damm: I'm not sure to follow you +10:26 < damm> ok +10:26 < geertu> So if the DRAM is configured to do decompression on the whole shadow area, it'll work? +10:27 < damm> so right now we reserve a physical memory range for decompression +10:27 < damm> geertu: i think it should be considered at least +10:27 < geertu> pinchartl: Does the FCP do mem-to-mem decompression? That needs and extra memory buffer +10:27 < geertu> s/and/an/ +10:27 < pinchartl> geertu: no it doesn't, the FCP operates on the fly only, as a proxy for the VSP and other MM IP cores +10:28 < damm> i say we don't reserve a range and instead rely on the shadow area (that's the same as mirror i guess) +10:28 < pinchartl> right +10:28 < pinchartl> I got it +10:28 < pinchartl> it's not that simple +10:28 < pinchartl> as data can be stored in memory in different formats +10:29 < pinchartl> each FCNL area is configured for a specific format +10:29 < damm> i think with such solution we could enable compression per-buffer +10:29 < damm> so can we use multiple shadow areas? +10:29 < pinchartl> well, I suppose we could divide the shadow area, yes +10:29 < pinchartl> the division of the shadow area should still be passed from ATF all the way to Linux though +10:30 < damm> then just look at the physical address to determine format +10:30 < damm> yes +10:30 < pinchartl> so we would use the same mechanism +10:30 < damm> i'm not sure it would work but i think it is worth checking +10:30 < damm> right +10:30 < pinchartl> and use regular DRAM addresses or shadow addresses depending on whether we need to decompress or not +10:31 < damm> exactly +10:31 < pinchartl> this assumes that the shadow area won't be used for a different purpose, do we have any information about that ? +10:31 < damm> nope +10:31 < pinchartl> ok +10:31 < damm> sorry =) +10:31 < pinchartl> in any case, I expect that the mechanism for passing memory information from ATF to Linux to be the same +10:32 < pinchartl> it's just the Linux side that would be more dynamic +10:32 < pinchartl> it will be interesting to handle in combination with the IOMMU... +10:32 < damm> yes! +10:32 < pinchartl> interesting as in "get me out of here" :-) +10:33 < geertu> pinchartl: Depends on which memory region is set up for FCNL +10:33 < geertu> Again, can we use ICRAM to pass the info? +10:33 < pinchartl> geertu: to pass the FDT from ATF to U-Boot ? +10:33 < geertu> pinchartl: yes +10:33 < pinchartl> I have no issue with that +10:33 < Marex> geertu: that'd be perfect, but do we know what exactly renesas hides in ICRAM and where ? +10:33 < pinchartl> it's out of my scope :-) +10:34 < geertu> Marex: The first 16 KiB turns out to be inaccessible +10:34 < Marex> geertu: I need about 4 kiB of it +10:34 < geertu> It's used for secondary CPU bringup +10:34 < geertu> On Gen2 , that's Linux domain ;-) +10:34 < Marex> geertu: there's also the certheader +10:34 < Marex> geertu: we need to avoid overwriting that too +10:34 < Marex> geertu: and if we decide on using ICRAM, which address is "good" for renesas ? +10:34 < geertu> Marex: Can we (are we allowed) to overwrite that? +10:35 < Marex> geertu: I'd rather not, and it should be possible to avoid it +10:35 < geertu> Marex: Ehat happens if we overwrite that? +10:35 < geertu> s/Ehat/What/ +10:36 < Marex> geertu: I didn't try +10:36 < geertu> Marex: If it's critical, ATF should protect it +10:36 < Marex> geertu: heh +10:36 < geertu> "4 kiB should be enough for everyone"? +10:37 < Marex> morimoto: what does renesas think? Is there a 4 kiB space in ICRAM which we can use for the DT ? +10:37 < Marex> morimoto: and if so, which address would be preferred ? +10:37 < Marex> geertu: keep in mind there are systems with 128 kiB ICRAM (D3 and E3 I think), so they are a bit more size constrained +10:38 < Marex> geertu: and ... oh, BL2 is in ICRAM :/ +10:39 < Marex> geertu: but I wonder if BL2 can have a buffer at fixed location for this FDT in it +10:39 < Marex> geertu: then it'd be in ICRAM and in control of the compiler/linker +10:39 < morimoto> Marex: I don't know, I need to ask BSP team. please wait. +10:40 < Marex> morimoto: speaking of BSP team, I wonder if Yokoyama-san would be willing to hang out on this fine IRC ? :) +10:40 < geertu> Does it have to be a fixed address? Header with magic value? +10:40 < Marex> morimoto: would be nice to cooperate with him on U-Boot more +10:41 < Marex> geertu: it has to be fixed, since we thus far have no way to pass the FDT address from ATF to U-Boot +10:41 < Marex> geertu: that's only gonna happen in ATF 2.0 I think +10:42 < geertu> Marex: As I said, search for a magic header value in ICRAM? +10:42 < Marex> geertu: if I can put the buffer at a fixed address with simple linker magic, I'd go for that +10:43 < geertu> Marex: Sure, but if that's not possible on all SoCs... +10:43 < Marex> geertu: why wouldn't it be ? +10:43 < Marex> geertu: size constraints ? +10:43 < pinchartl> if the magic header can be searched on page boundaries it shouldn't be much of an overhead +10:44 < pinchartl> but if the address can also be fixed, it should be even less of an overhead :-) +10:44 < geertu> Marex: as you said, some SoCs have less ICRAM, and may use different parts for other purposes +10:46 < Marex> geertu: only D3 it seems +10:46 < geertu> Marex: Have you checked H3-N? +10:46 < Marex> I dont have minimon sources for H3N +10:46 < Marex> geertu: let's see the docs +10:46 < geertu> And the other unknown SoC being produced the day after tomorrow? +10:47 < Marex> geertu: silicon/next ? +10:47 < Marex> geertu: anyway, if we can put it into ICRAM, good +10:47 < damm> it can't be too difficult to read SoC version register (PRR?) and from there go for per-SoC base address if needed? +10:47 < Marex> geertu: then the question is, would renesas be willing to take the ATF patches ? +10:48 < Marex> damm: but unified == better +10:48 < damm> sure +10:48 < Marex> damm: I had this idea ... +10:48 < damm> we can be unified with what we have today, and special case upcoming stuff +10:48 < morimoto> Marex: I asked to BSP team, but it is implemented/using by 3rd party. So they don't know detail. If you can send me question mail, I can forward it to BSP/3rd party. +10:48 < Marex> damm: IFF ATF can pass board compatible string, U-Boot can select the right DT and then we can have single U-Boot for all Gen3 boards +10:48 < Marex> *gasp* +10:49 < Marex> morimoto: ATF ? +10:49 < damm> not bad +10:49 < Marex> geertu: the ICRAM is not documented in the datasheet, is it ? +10:50 < geertu> Marex: 21A System RAM? +10:51 < Marex> geertu: so D3/E3 could be an issue +10:51 < Marex> since I have ebisu, I can try +10:51 < morimoto> Marex: It was for 4kiB space in ICRAM +10:52 < morimoto> And it seems Yokoyama-san already go back to home today +10:52 < Marex> morimoto: sorry for keeping you here for so long +10:52 < morimoto> np +10:54 < geertu> Time to wrap up, and pass the torch^H^H^H^H^Hmic to pinchartl? +10:54 < Marex> geertu: well, let's try bundling the FDT into ICRAM then +10:54 < Marex> geertu: or, BL2 +10:55 < pinchartl> geertu: whenever you want +10:55 < pinchartl> we're only one hour late :-) +10:56 < geertu> And Niklas is still busy ;-) +10:56 < geertu> Let's fin(n)ish this ;-) +10:56 < geertu> Thanks for joining, and have a nice continued day! diff --git a/wiki/Chat_log/20181018-io-chatlog b/wiki/Chat_log/20181018-io-chatlog new file mode 100644 index 0000000..250108a --- /dev/null +++ b/wiki/Chat_log/20181018-io-chatlog @@ -0,0 +1,207 @@ +09:05 < wsa_> welcome to this io meeting everyone +09:06 < wsa_> here is the collected status update +09:06 < wsa_> Status updates +09:06 < wsa_> ============== +09:06 < wsa_> A - what have I done since last time +09:06 < wsa_> ------------------------------------ +09:06 < wsa_> Geert +09:06 < wsa_> : fixed receive regression on SCIFA/B with DMA, tested MSIOF with DMA on Ebisu, +09:06 < wsa_> optimized AT25 SPI EEPROM driver for DMA, posted RFC to fix fallback to PIO +09:06 < wsa_> in the sh-sci driver +09:06 < wsa_> Kaneko-san +09:06 < wsa_> : got E3 SYS-DMAC enablement for MSIOF merged +09:06 < wsa_> Marek +09:06 < wsa_> : implemented PCIe SError recovery in ATF to handle link state problems +09:06 < wsa_> Niklas +09:06 < wsa_> : sent a new version of the SDHI reset series and prepared a summary of the +09:06 < wsa_> HS400 clock divider issue +09:06 < wsa_> Shimoda-san +09:06 < wsa_> : reviewed RZ/G1C's USB2.0 host/peripheral proposal, proxied an issue of sh-sci +09:06 < wsa_> with Gen2 (SCIFA) + dmaengine, added D3/E3 support to renesas_usbhs and +09:06 < wsa_> phy-rcar-gen3-usb2, fixed gadget/udc/renesas_usb3 for E3, and confirmed the +09:06 < wsa_> eMMC suspend issue is gone in latest LTSI +09:06 < wsa_> Wolfram +09:06 < wsa_> : did organizational preparations for PeriPeriCon and SDHI-Hackfest in Edinburgh, +09:06 < wsa_> reviewed and tested various SDHI and SCIF patches, prepared another cleanup +09:06 < wsa_> series regarding dev_get_drvdata(), sent RFC to Shimoda-san's question about +09:06 < wsa_> clearing DMA in i2c-rcar, assisted Fabrizio with his I2C passthrough issue, +09:06 < wsa_> and updated his DMA talk for the ELCE conference +09:06 < wsa_> B - what I want to do until next time +09:06 < wsa_> ------------------------------------- +09:06 < wsa_> Marek +09:06 < wsa_> : wants to go to ELCE, PeriPeriCon, SDHI hackfest in Edinburgh +09:06 < wsa_> Niklas +09:06 < wsa_> : wants to attend ELCE and the SDHI hackfest +09:06 < wsa_> Shimoda-san +09:06 < wsa_> : wants to work on KVM + QEMU + USB and update information to elinux wiki +09:06 < wsa_> Simon +09:06 < wsa_> : wants to investigate RAVB no-link patches in BSP 3.7.2 +09:06 < wsa_> Wolfram +09:06 < wsa_> : wants to pick up the I2C core PM rework again, upport more patches, and +09:06 < wsa_> organize PeriPeriCon and SDHI-Hackfest in Edinburgh +09:06 < wsa_> C - problems I currently have +09:06 < wsa_> ----------------------------- +09:06 < wsa_> Marek +09:06 < wsa_> : wants to know how we can get the ATF patches into the Renesas ATF release?

Additional Tasks for Q4 +11:42 < pinchartl> The following additional tasks have been submitted and approved, they are now going through the usual process.

Whether it's keeping firmware out - or just completley hiding the implementation altogether. But once there is a standard API for codecs - It would be silly not to use it - and it seems unfortunate not to be part of those early designs +11:50 < pinchartl> I would like to also briefly discuss the GMSL and FPD-Link plans +11:50 < kbingham> Yes :) +11:51 < pinchartl> kbingham: I'll add codecs to the agenda, we can then spend some time discussing how to report the ongoing V4L2 codecs API developments to Renesas +11:51 < pinchartl> any other topic ? +11:52 < jmondi> not from here, thanks +11:52 < kbingham> Dont think so ... +11:53 < neg> not from me +11:53 < morimoto> not from me too +11:53 < morimoto> s/too/either/ +11:55 < pinchartl> ok, thanks +11:55 < pinchartl> in that case +11:55 < pinchartl> Topic 5.

I have done a small task to help define the schema ... I am not assuming that I now own periject ... so I'm concerned that it is losing direction and management fast ! +10:13 < pinchartl> morimoto: ^^ +10:13 < pinchartl> kbingham: you may well be the owner now :-) +10:16 < pinchartl> seems there's a lack of volunteers ? +10:17 < morimoto> according to EthPad (http://muistio.tieke.fi/p/ppcedi18) +10:17 < morimoto> I can do is create git tree +10:19 < kbingham> Aha - we have earlier defined action points. +10:20 < kbingham> morimoto, could you let me know where to push the patches I have done so far then please? +10:21 < pinchartl> morimoto: about the next steps, would you like to continue development with Kieran ? +10:21 < morimoto> development what ? +10:22 < pinchartl> development of periject +10:22 < morimoto> kbingham: do you want to have new clean git repository ? +10:22 < morimoto> or contine +10:23 < morimoto> continue to use exist one ? +10:23 < morimoto> I can do both +10:25 < kbingham> I would have said continue to use the existing one - but there is quite a lot of code that would need to be ported to the new formats. So that makes me think a clean repository, as we import existing functionality on the new data format. What do you think ? +10:26 < morimoto> OK, no problem +10:26 < morimoto> I will remove existing periject, and create new clean one +10:27 < kbingham> morimoto, Don't 'remove' it completely :) +10:27 < pinchartl> or create a new branch in the existing repo ? +10:27 < morimoto> kbingham: I don't think we can reuse it +10:28 < morimoto> OK, not remove, but rename. periject -> periject-nack +10:31 < kbingham> Well either a new branch, in the same repo - or a fresh repo (whilst keeping the existing code in a separate) repo is fine by me. I think it's important to keep the existing code as reference for the design goals you had +10:31 < geertu> Yes, just rename the old master branch. +10:32 < morimoto> OK, move existing code to new branch, and create clean main branch ! +10:34 < kbingham> Ok great. So I saw wsa_ had interest in participation from the EDI notes... +10:35 < kbingham> wsa_, Is there anything blocking you currently ? +10:35 < wsa_> what kind of "participation"? +10:35 < kbingham> wsa_, "Peri upport list # Wofram : migrate data # Wolfram" +10:36 < wsa_> the discussions i saw on the mailing list were YAML state details where I had no strong opinion on +10:36 < wsa_> ah, that +10:36 < wsa_> yes, I am still there for that +10:36 < kbingham> wsa_, Great ... is there anything blocking you from doing it :) (other than time.. :D) +10:37 < wsa_> yes, a notification like "everything you need for that is in place now" :) +10:37 < wsa_> like YAML scheme being ready, repo to work on +10:37 < wsa_> "ready enough" is good enough, too +10:38 < kbingham> Well then you can reply to the YAML schema saying 'Acked-by:' then :) +10:38 < kbingham> The YAML schema is 'close enough' as far as I can tell... +10:39 < kbingham> And it can still change where necessary ... +10:39 < wsa_> good to know +10:39 < kbingham> So having some real data put in and run with the validator to know if it works would certainly help. +10:39 < wsa_> okay +10:39 < wsa_> morimoto: can you announce when the updated repo is ready? +10:40 < morimoto> Yeah +10:40 < wsa_> on periperi-list? +10:40 < wsa_> great +10:40 < wsa_> thanks! +10:40 < morimoto> Maybe tomorrow +10:40 < morimoto> (Japanese time zone, of course :) +10:42 < kbingham> Ok - so we have some progress points ... +10:42 < kbingham> Shall we move on - and try to continue this in the ML? +10:42 < wsa_> ack +10:44 < pinchartl> should we proceed with multimedia then ? +10:44 < geertu> I think so, unless someone has another Core discussion topic? +10:45 < neg> I'm all cored out :-) +10:45 < pinchartl> :-) +10:46 < geertu> Thanks for joining, and have a nice continued day! diff --git a/wiki/Chat_log/20181206-io-chatlog b/wiki/Chat_log/20181206-io-chatlog new file mode 100644 index 0000000..e726f66 --- /dev/null +++ b/wiki/Chat_log/20181206-io-chatlog @@ -0,0 +1,152 @@ +09:04 < wsa_> ah, simon is excused +09:04 < wsa_> in which timezone is he now?

+09:08 < pinchartl> C - The pwm-rcar driver is broken with the PWM atomic API +09:08 < Marex> wsa_: I hope so, I need to rebase the PCI patch on top of upstream ATF, since they added all of the exception handling boilerplate and the patch doesn't apply anymore, but besides that, it should be doable +09:09 < wsa_> also, (not super much IO but upporting): who has a D3 board? According to the list, jmondi and Uli. Sound support needs to be upported... +09:09 < pinchartl> wsa_: I have Jacopo's D3 board, we exchanged the D3 and E3 +09:10 < shimoda> wsa_: about D3, I also have a board +09:10 < pinchartl> I thought I had updated the wiki, does it still show the D3 as being with Jacopo ? +09:10 < wsa_> pinchartl: will add the PWM issue to C), thanks! +09:10 < geertu> General comment: please update https://osdr.renesas.com/projects/linux-kernel-development/wiki/Hardware +09:11 < wsa_> pinchartl: you have. that was a race condition :D +09:11 < jmondi> ups, forgot to update this ^ +09:11 < jmondi> but somebody did already :) +09:12 < wsa_> so, if somebody is interested in that, there are some Jinso-patches for that on the list... +09:14 < wsa_> with simon not being here, that were all of my questions, I guess +09:14 < wsa_> are there some more from you, guys? +09:15 < pinchartl> if there's nothing else to discuss, I'd like to know if someone would like to address the PWM issue +09:15 < Marex> wsa_: speaking of D3/E3, I'm still curious about the HS400 performance on E3, it's lower than on M3N (with the same controller and same eMMC), both on BSP and mainline U-Boot +09:15 < geertu> Shimoda-san enquired about using VFIO. +09:15 < wsa_> shimoda: pinchartl: I assume you are linked now concerning the PWM issue? +09:15 < Marex> wsa_: I wonder if that's a QoS thing (if I fiddle with the QoS settings in ATF, it does affect that a bit) or something else +09:16 < neg> a cross IO/core question, do you think it's possible for us to aim to enable HS400 for 4.21 or are we a tad to late? +09:16 < pinchartl> shimoda: do you have time to work on pwm-rcar, or should I try to fix the problem ? +09:16 < wsa_> neg: I would very much hope so +09:17 < shimoda> pinchartl: i have time to work on pwm-rcar +09:17 < wsa_> neg: we could ask geertu if he is happy with the clock patches :) +09:17 < wsa_> neg: from the reviews, only minor stuff needs to be changed +09:18 < geertu> I plan to apply the clock patches, with the two nits fixed. +09:18 < shimoda> pinchartl: so I'd like to know how to reproduce the issue. +09:18 < geertu> And send a PR tomorrow. +09:18 < pinchartl> shimoda: great :-) I noticed the issue with backlight on E3, but I think it can be reproduced on any board. the problem comes from using the PWM atomic API. as the pwm-rcar driver doesn't suport it natively, the PWM core translates the calls to the legacy PWM API (set config, enable). the sequence of calls doesn't work well +09:18 < wsa_> geertu: one nit was not in the commit message but only in the changelog +09:19 < neg> wsa_: Yes even so I noticed Simon closed the renesas tree yesterday for 4.21 but maybe he can take it anyhow. Will ask him once he is awake +09:19 < geertu> wsa_: Which one? +09:19 < wsa_> s/rete/rate/ +09:19 < pinchartl> rcar_pwm_config() returns immediately because pwm->state.duty_cycle = 0 +09:20 < pinchartl> and then rcar_pwm_enable() will return an error because RCAR_PWMCNT_CYC0 == 0 and RCAR_PWMCNT_PH0 == 0 +09:20 < wsa_> neg: can you resend the other patch ASAP? +09:20 * geertu has a PWM déjà vue +09:20 < geertu> s/vue/vu/ +09:21 < pinchartl> so I think we need rcar_pwm_config() first compute the config parameters and store them, and then return if the PWM is not enabled, or program the hardware if it is +09:21 < wsa_> then let's hope simon will make an exception for the final HS400 DTS enablement patch +09:21 < pinchartl> then rcar_pwm_enable() should always proceed with the stored config +09:21 < pinchartl> and program the hardware if it's not programmed yet +09:21 < shimoda> pinchartl: I didn't know about the PWM atomic API. I'll check that. as you said, the driver prevents to enable it with CYC0 == 0 and PH0 == 0. +09:21 < geertu> Simon is still applying patches. +09:22 < neg> wsa_: I talked to geertu about the patches yesterday and he has generously agreed to fix the nit commetns when applying them. My question was more about if it was to late for the HS400 DT patch +09:22 < wsa_> neg: I don't think so :) +09:22 < neg> good :-) +09:23 < pinchartl> shimoda: it's a chicken and egg problem. rcar_pwm_config() doesn't program RCAR_PWMCNT because the channel is disabled, and then rcar_pwm_enable() errors out because RCAR_PWMCNT isn't programmed :-) +09:24 < geertu> Is this a recent PWM issue? +09:24 < pinchartl> one option to test this is to use my git://linuxtv.org/pinchartl/media.git drm/du/d3e3 branch +09:25 < pinchartl> make sure to compile the pwm-backlight driver +09:25 < pinchartl> then you can control the backlight from sysfs +09:25 < pinchartl> in /sys/class/backlight +09:25 < pinchartl> pwm-backlight now uses the PWM atomic API +09:25 < pinchartl> geertu: I don't think it's new, what has changed is the way client drivers use the PWM API +09:26 < pinchartl> the call sequence was always valid +09:26 < pinchartl> but never tested +09:26 < wsa_> eeeks, my thunderbird crashes badly...(?) so I can't look now... is there somebody at the ethernet breakage that Marex bisected? +09:26 < shimoda> pinchartl: :) so, i added a trickly code at line 157 of pwm-rcar.c. But, I think I should support .apply ops instead of legacy ops +09:27 < pinchartl> that would of course be a good option too :-) +09:27 < geertu> wsa_: It's hch's DMA cleanup +09:27 < geertu> Marex pointed to https://patchwork.kernel.org/patch/10668093/ +09:27 < wsa_> geertu: i see. thanks +09:28 < geertu> Aboiut Shimoda-san's VFIO question +09:28 < geertu> The answer is "yes, you can". SATA is the most mature example. You still need to apply out-of-tree kernel and qemu patches, cfr. https://elinux.org/R-Car/Virtualization/VFIO +09:28 < pinchartl> shimoda: the apply operation should be easier to implement for the driver, and should fix the probleem +09:29 < pinchartl> that's all on my side for pwm-rcar +09:29 < Marex> wsa_: the link also contains a patch , which fixes the breakage +09:29 < wsa_> cool +09:29 < pinchartl> on a different, common topic, I would like to talk about peripericon @FOSDEM2019. we can do that now or later as part of core or multimedia +09:30 < shimoda> pinchartl: thank you for the detailed information! I'll try to implement the apply operation. +09:30 < wsa_> Yeah, I'd like to talk about that if there are no more IO related questions? +09:30 < Marex> wsa_: speaking of D3/E3, I'm still curious about the HS400 performance on E3, it's lower than on M3N (with the same controller and same eMMC), both on BSP and mainline U-Boot +09:30 < Marex> wsa_: I wonder if that's a QoS thing (if I fiddle with the QoS settings in ATF, it does affect that a bit) or something else +09:30 < wsa_> shimoda: cool, thanks for taking care of that. +09:31 < shimoda> geertu: thank you aboit VFIO. I didn't check the eLinux page. I'll check it after I made a patch for pwm-rcar :) +09:31 < wsa_> Marex: did you try using the BSP also? +09:31 < geertu> shimoda: You're welcome.

I think it should be taken up with the clock maintainers. +09:40 < geertu> Usually the rate is unsigned long, but there are a few places where long is used. +09:40 < shimoda> why BSP team realized this topic because they used static analyses (QAC) +09:41 < geertu> If long is used, a negative value is used to indicate an error code. +09:41 < geertu> Since error codes are small negative numbers, one approach to solve this would be similar to IS_ERR(), which uses +09:41 < geertu> #define IS_ERR_VALUE(x) unlikely((unsigned long)(void *)(x) >= (unsigned long)-MAX_ERRNO) +09:42 < geertu> with MAX_ERRNO = 4095, that would allow up to 4.2 GHz. +09:42 < geertu> Of course doing that would require many changes in code handling long rates, plus it's not a final solution. +09:43 < Marex> shimoda: maybe you can compile 32bit kernel and run it on H3 in 32bit mode ? +09:43 < Marex> shimoda: at least raspi3 is capable of running 32bit kernel on arm64 CPU, and H3 has some 3.2 GHz bus in it IIRC +09:43 < geertu> IIRC, the general census (hope?) was that high-rate clocks are contained on 64-bit architectures, where long is 64-bit +09:44 < shimoda> Marex: yes, but I never try it though. +09:44 < geertu> Marex: Even the old Cell Broadband Engine ran at 3.2 GHz +09:44 < Marex> geertu: the VC5 also has ~2.9GHz PLL and it can be well connected to 32bit CPU +09:45 < Marex> I guess there are many 32bit systems with > 2GHz clock +09:46 < geertu> [PATCH v2 00/34] change clk_ops->round_rate to scale past LONG_MAX +09:46 < geertu> https://lore.kernel.org/lkml/1514833681-30737-1-git-send-email-pure.logic@nexus-software.ie/ +09:47 < geertu> v1 did fave feedback +09:47 < geertu> https://lore.kernel.org/lkml/20180102190159.GH7997@codeaurora.org/ +09:47 < Marex> shimoda: I didn't try it either, I'd expect a few things to break there too +09:48 < geertu> implement the determine_rate op instead of the +09:48 < geertu> round_rate op +09:50 < geertu> None of the drivers/clk/renesas/ drivers implement that yet +09:50 < geertu> So that seems the way to go, for now. +09:51 < shimoda> geertu: oh, thank you for the information! so, now we can use up to 4GHz on 32bit arch if we add the determine_rate op on drivers/clk/renesas +09:51 < geertu> shimoda: Does that answe your question? +09:51 < shimoda> geertu: yes, thanks! +09:51 < Marex> geertu: isn't that more of a workaround ? +09:52 < geertu> Marex: More or less.

Igalia is working on Chromium support, and Chromium uses render nodes to +10:15 < pinchartl> separates the UI process and the GPU rendering for speed-up. +10:15 < pinchartl> [1] https://en.wikipedia.org/wiki/Direct_Rendering_Manager#Render_nodes +10:15 < pinchartl> [2] https://01.org/linuxgraphics/gfx-docs/drm/drmExternals.html +10:15 < pinchartl> Tomohito Esaki from Igel has created a "quick hack" solution and provided a test +10:15 < pinchartl> application. The BSP team would like to know our opinion. +10:15 < pinchartl> morimoto: this may be a stupid question, but +10:15 < pinchartl> the DU doesn't have rendering support, as we have a separate GPU for that +10:16 < pinchartl> why would the DU driver need to create a render node when it can't do rendering ? :-) +10:16 < pinchartl> the GPU node should create the buffers, and they should be imported by the DU driver normally +10:16 < pinchartl> the render node API shouldn't be needed for that +10:16 < morimoto> "DU doesn't have rendering support" = "HW" or "SW " ? I think "SW" +10:17 < pinchartl> neither +10:17 < pinchartl> the DU can compose multiple planes +10:17 < pinchartl> but the DU hardware can't do rendering, it's not a GPU +10:18 < pinchartl> so there's no rendering support in the driver because there's no rendering support in the hardware :-) +10:18 < damm> Can IMR do rendering? +10:18 < morimoto> Ahh, OK, thanks. I was misunderstanding +10:18 < pinchartl> damm: IMR does some kind of rendering +10:19 < pinchartl> as such it would be nice to support it with a DRM driver (and that would create a render node) +10:19 < pinchartl> but it seems that the direction that was chosen was to use V4L2 instead +10:19 < pinchartl> for the GPU I certainly hope V4L2 won't be used :-) +10:19 < damm> i think the input from the m/m group leader is highly regarded +10:19 < pinchartl> but DRM may not either, and that's out of our control +10:20 < pinchartl> I commented on that in the past I believe +10:20 < pinchartl> I think that was when Cogent posted IMR patches +10:20 < pinchartl> (I'd have to check though, it was a long time ago) +10:20 < morimoto> [PATCH v5] media: platform: Renesas IMR driver +10:20 < morimoto> > https://lore.kernel.org/linux-renesas-soc/20170309200818.786255823@cogentembedded.com/ +10:20 < morimoto> ? +10:20 < damm> gotcha. thanks +10:22 * kbingham likes that lore is getting good use :) +10:22 < pinchartl> morimoto: that driver, yes.

minimon ? +09:58 < pinchartl> neg: last time I wanted to update the Draak firmware it took me a whole day +09:59 < Marex> morimoto: jupp, the piece of software that you start from SCIF loader and use to update the flash on Gen3 +09:59 < pinchartl> unlike other boards, there's no minimon binary for Draak in the wiki, that didn't help +09:59 < Marex> pinchartl: the draak in Magnus's vlab supports 'fitupd' from U-Boot +10:00 < Marex> pinchartl: wait until I get physical access to it, then I'll push proper ATF port upstream and then you can unlock HF and update via U-Boot +10:00 < pinchartl> Marex: mine doesn't :-) +10:00 < pinchartl> and to update u-boot I needed a flash writer +10:00 < Marex> pinchartl: the current ATF port is kinda meh, it's better than what it came with, but still downstream +10:00 < Marex> pinchartl: well, only once ... +10:00 < pinchartl> sure +10:00 < Marex> pinchartl: soon you'll be able to use U-Boot SPL on some platforms ... +10:01 < Marex> pinchartl: that's kinda work in progress +10:01 < pinchartl> but until then, flash-writer is needed +10:01 < wsa> you need a can-opener once :) +10:01 < pinchartl> in any case, we need a solution for the current problems. if we can improve the situation even more in the future, I'll be very happy +10:02 < pinchartl> Marex: will U-Boot SPL support being loaded over SCIF ? +10:02 < geertu> And you need to make ATF builds point-and-click once ;-) +10:02 < Marex> pinchartl: already does, although it's a bit hacky, which is why it needs cleanup first +10:02 < pinchartl> ok +10:04 < pinchartl> in the meantime, I think a canonical source of instructions on how to retrieve a working minimon binary for each board, or build flash-writer, would be very useful too +10:04 < pinchartl> the expect scripts shouldn't be in the wiki, they should be in a git tree +10:04 < Marex> pinchartl: feel free to take that one up, and put it on the OSDR (!) wiki +10:04 < Marex> pinchartl: this stuff is not public +10:04 < pinchartl> we can have a private git tree for that +10:05 < Marex> pinchartl: btw are we still in the core meeting ? +10:05 < pinchartl> I won't have time to take this one up I'm afraid +10:05 < pinchartl> I believe we are, this doesn't sound like multimedia to me :-) +10:05 < Marex> pinchartl: I have no interest in minimon, except for extracting knowledge burried in it's sources +10:05 < Marex> pinchartl: U-Boot has some sound support, FYI +10:07 < geertu> Let's start with the other parts +10:07 < pinchartl> Marex: oh ? what is sound used for in u-boot ? +10:07 < neg> Marex: wake me up when it supports VIN ;-P +10:07 < kbingham> beep() :D +10:08 < Marex> pinchartl: dunno, x86 people use it for something ... +10:08 < Marex> pinchartl: maybe the nice blurpy sound apple does on boot ... +10:08 < geertu> Can we (you) start with the actual firmware parts, thus not including minimon? +10:10 < Marex> morimoto: btw. updated minimon sources are super-low prio , I think you'd have to go through export paperwork and all other kind of hassle , so don't worry about it too much +10:10 < morimoto> Marex: OK, thanks :) +10:10 < Marex> geertu: didn't I say I added item to my TW to document it on elinux wiki ? +10:10 < geertu> As all the actual firmware parts are FLOSS, there's no issue here +10:11 < geertu> Marex: Good! +10:11 < geertu> Thanks! +10:11 < geertu> Any other topics to discuss for core? +10:11 < morimoto> geertu +10:11 < geertu> Periject path forward?

But that needs to be enabled in firmware, too? +09:45 < geertu> And how does access control work in that case? +09:46 < Marex> geertu: "that" ? +09:46 < Marex> geertu: Linux is running in non-secure world and optee OS is the access controller +09:47 < Marex> that's my understanding of the bare bones situation +09:48 < geertu> Marex: Can it distinguish between my Linux or your Linux? +09:48 < Marex> geertu: there is some setting where optee os boots the next stage (u-boot), so it can authenticate what it starts +09:49 < Marex> geertu: and it can block your linux from running at all +09:50 < Marex> geertu: whether it can authenticate requests from random stuff in the non-secure world, I didn't check ; presumably yes +09:52 < geertu> ok +09:53 < Marex> geertu: optee OS upporting is on my list, when I get to it, I'll know more +09:53 < geertu> Marex: Great! +09:53 < Marex> geertu: ... is what you think, until you see the code :) +09:54 < Marex> morimoto: off-topic, when shall we meet tomorrow ? +09:55 < morimoto> Marex: 13:00 at Kokubuji ? +09:56 < geertu> Next Core Group Chat date? +09:56 < geertu> I won't be available in two weeks. +09:57 < marex-cloud> morimoto: Roger! +09:58 < pinchartl> geertu: I'm afraid I won't be available in 3 weeks +09:58 < shimoda> geertu: how about 18th Apr? +09:58 < geertu> shimoda: That's in two weeks ;-) +09:58 < morimoto> pinchartl: because Sky :) ? +09:58 < pinchartl> morimoto: I wish. because work :-) +09:59 < morimoto> pinchartl: ohh... orz +09:59 < horms> I will be on a break on the 18th.

I would thus like to finalize the plan based on the feedback from the BSP team, and then discuss together how we can create SoWs that keep the concept of additional tasks, but make that fit with larger development +10:39 < pinchartl> do you know when we could receive feedback on the proposals ? +10:40 < morimoto> from BSP team ? +10:40 < pinchartl> yes +10:40 < morimoto> I'm waiting it. I will send ping to them +10:41 < pinchartl> thank you +10:42 < pinchartl> any other question or comment ? +10:43 < neg> Is it too early to start to plan Renesas days around OSSJ ? +10:43 < pinchartl> I'd say the earlier the better +10:44 < pinchartl> the first question is then, will we have a periperi meeting in Japan ? +10:44 < pinchartl> (around OSSJ- +10:44 < pinchartl> ) +10:45 < pinchartl> morimoto: any plan on Renesas side ? +10:45 < morimoto> No plan so far +10:46 < pinchartl> morimoto: do you think we should make a plan ? :-) +10:46 < wsa> I am not going to OSSJ this year, too many schedule conflicts :( +10:46 < pinchartl> wsa: :-( +10:46 < morimoto> I'm plannng so far for OSSJ is Chanko which is requested from wsa +10:46 < pinchartl> how about everybody else, who plans to go, who will not go, and who is still undecided ? +10:46 < morimoto> wsa: Grrr you don't this year +10:47 < pinchartl> I know Kieran will likely not be able to join, due to having a wedding on both sides of the conference +10:47 < wsa> morimoto: didn't i tell you? +10:47 < uli___> i intend to go +10:47 < pinchartl> (getting married once is already crazy, having two weddings is even worse if you ask me :-)) +10:47 < pinchartl> uli___: that's the right decision :-) +10:47 < kbingham> Correct. OSSJ is highly unlikekly for me I'm afraid. +10:47 < morimoto> wsa: did you ? I don't remember... +10:47 < wsa> i thought we discussed OSSJ attendance somewhen already on IRC +10:48 < pinchartl> geertu: how about you ? +10:48 < neg> kbingham: will the divorce papers clear in time for the second wedding? +10:48 < pinchartl> horms: same question ? +10:48 < wsa> morimoto: I'm sad myself :'-( +10:49 < kbingham> neg, They'll be fine. +10:49 < horms> If the question is about OSSJ then the answer is that I currently have no plans to attend +10:49 < morimoto> wsa: I will miss you, so much... +10:49 < pinchartl> horms: yes, that was the question. would you make plans to attend if needed, or is that unlikely ? +10:50 < wsa> maybe we should do this by email, but what about you guys attending Plumbers (Lisboa) and/or Embedded/Kernel-Recipes (Paris) in September +10:50 < wsa> ? +10:50 < wsa> morimoto: will we meet in Lyon at ELCE? +10:50 < pinchartl> wsa: LPC or ELCE would be a good idea too +10:50 < morimoto> Maybe I can't joint to ELCE this year +10:51 < morimoto> s/joint/join/ +10:51 < pinchartl> morimoto: I suppose it depends on the budget situation, and we will only know about it later ? +10:52 < pinchartl> geertu: ping ? +10:52 < horms> pinchartl: if its important I can make a plan. but other plans would work better for me, f.e. I do plan to attend LPC and ELCE would take me about as long to drive to as it would to fly to OSSJ +10:53 < pinchartl> horms: ok +10:53 < pinchartl> so a whole periperi meeting seems more likely at LPC or ELCE time than OSSJ time at the moment +10:53 < pinchartl> I have submitted a talk proposal for OSSJ so I will likely go +10:54 < pinchartl> maybe we'll have a MM meeting instead of a global meeting then +10:54 < geertu> pinchartl: I can go to OSSJ +10:55 < pinchartl> geertu: nice :-) +10:55 < geertu> I will be at Embedded-Recipes (invited speaker) +10:55 < wsa> same here for Embedded Recipes +10:55 < geertu> It's been 3 years since I've been to JP :-( +10:55 < wsa> not sure about Plumbers yet +10:55 < geertu> wsa: Marex did a good job ;-) +10:55 < pinchartl> what will you speak about at RC ? +10:55 < wsa> yes :D +10:55 < pinchartl> s/RC/ER/ +10:56 < geertu> pinchartl: No topic set so far +10:56 < wsa> similar here, a rough idea was to speak about my subsystem (new things, workflow...) +10:56 * geertu considers a talk about the Japanese cherry tree in his garden +10:58 < pinchartl> :-) +10:58 < geertu> Probably I should install a camra to take daily Sakura pictures +10:58 < wsa> morimoto: you are not coming to Lyon? Well, looks like I need to find another excuse than OSSJ to come to Japan then :) +10:58 < geertu> And I plan to attend ELCE, as usual +10:59 < geertu> (until LF has exploded by then) +10:59 < geertu> s/until/unless/ +11:00 < pinchartl> any plan to make LF explode ? +11:00 < wsa> Yeah, I plan for ELCE, too +11:01 < morimoto> wsa: yeah, I can't this year. so sorry +11:01 < geertu> http://techrights.org/2019/03/30/what-happened-lf/ +11:02 < pinchartl> geertu: interesting, I had missed that +11:02 < pinchartl> anyway, the conclusion for now is +11:02 < pinchartl> likely no official global meeting around OSSJ +11:02 < pinchartl> perhaps a multimedia meeting +11:03 < pinchartl> and perhaps a global meeting around LPC or ELCE (but that is likely conditioned by budget) +11:03 < pinchartl> next discussion topic for the MM meeting +11:03 < pinchartl> additional tasks for Q2 +11:03 < pinchartl> as discussed before, the plan is to makes those tasks fit in the global MM development plan +11:04 < pinchartl> I would like to already move forward with tasks related to the request API +11:04 < pinchartl> for other tasks, I would like to first receive feedback from the BSP team on the plan +11:04 < pinchartl> neg: if I understand correctly, you have all your additional task time allocated already for Q2, right ? +11:06 < marex-cloud> morimoto: I'll likely be at OSSJ :) +11:06 < geertu> marex-cloud: Critical mass reached! +11:07 < marex-cloud> geertu: heh +11:07 < neg> pinchartl: yes Q2 already allocated +11:07 < marex-cloud> geertu: I'll also be at ER most likely, I seem to be roped into a special role +11:07 < pinchartl> neg: thanks +11:08 < marex-cloud> geertu: godfather was the name I think +11:08 < pinchartl> so I'll work on a proposal for the request API already, and wait for feedback for the rest +11:08 < pinchartl> any other dicussion topic for today ? +11:09 < neg> not from me, thanks +11:09 < morimoto> marex-cloud: nice to know :) +11:09 < marex-cloud> geertu: what about doing a trip to Toyama around OSSJ, eat great food etc? +11:09 < pinchartl> I then propose adjourning this meeting. does anyone second ?

How about to add "remain BSP patches" file +09:35 < pinchartl> but BSP patches != tasks ... +09:35 < pinchartl> I don't want to create a task titled "Do not port these BSP MM patches" that refers to BSP patches that I don't want to upport +09:37 < pinchartl> I fully agree that for BSP patches that we want to upport we should create tasks +09:37 < pinchartl> but it's the other ones that we have no good way to handle +09:38 < wsa> The way I handle it: some topics get a dedicated task, like "SDHI: HS400 autocorrection". The leftovers get a task like "bsp395: upport SDHI patches". In there, I can comment on them to be not upported +09:40 < pinchartl> I don't like that much :-( +09:40 < pinchartl> to me periupport is similar to patchwork +09:40 < pinchartl> it tracks commits +09:40 < pinchartl> to make sure none of them gets forgotten +09:40 < pinchartl> while periject is a task tracker +09:42 < morimoto> I don't understand what is the issue ... +09:42 < morimoto> How about this ? +09:42 < morimoto> task name = "sort BSP patches" +09:42 < morimoto> you can list up all remain patches. +09:42 < morimoto> you can use comment or tag or something to mark up. +09:42 < morimoto> pick up them if it could tasks. +09:43 < geertu> Thigns become complicated when combining multiple commits in a single task, with different paths forward +09:43 < pinchartl> that would be like replacing patchwork by a process that adds an entry in a bugzilla titled "Handle patches posted to the mailing list" and then using it to track the state of patches +09:44 < pinchartl> we *could* do something like that, but it's quite a hack, and I don't think it would be very practical +09:44 < wsa> pinchartl: send patches :) +09:44 < pinchartl> wsa: for what ? :-) +09:45 < shimoda> pinchartl: in other words, you'd like to maintain both periupport and periject? +09:45 < wsa> pinchartl: whatever you like +09:46 < pinchartl> shimoda: yes and no. I think the two tools handle different needs. but I also think we could integrate periupport in periject if we wanted to, but in that case we should have a ticket file similar to what we have today in periject +09:46 < pinchartl> (possibly in a different format, we can standardize everything on yaml if we want, but the idea remains the same) +09:47 < geertu> Hence new BSP commits start with being an individual new periject ticket, but may be absorbed/aggreated into a larger task? +09:47 < geertu> s/ticket/task/ +09:47 < pinchartl> geertu: no, I don't think we should create a ticket for each BSP commit +09:48 < pinchartl> BSP commits would be stored in a single file like we do in periupport, and we would create tasks out of them as we plan/perform the backporting +09:48 < pinchartl> one ticket per BSP commit would soon become very, very impractical +09:49 < pinchartl> but in any case I don't think I'll win this fight, as none of us will have time to specify how this would be handled, not even talking about implementing the tooling :-) +09:49 < neg> How about a bsp-commit.txt file similar to periupport, in it one can nack a patch and give a reason. Then add some visualisation of the delta of patches that should be upported but are not listed in any task file ? +09:49 < pinchartl> neg: I think that's what I meant by importing a periupport-style BSP commits file, yes +09:50 < pinchartl> (again, could be in the same format as today, or we could use yaml if we wanted to store everything in yaml) +09:51 < wsa> pinchartl: I don't think it is a fight. It is just about spending time on it as you mentioned +09:52 < pinchartl> wsa: it was just a metaphor, but not the best choice of word, I agree +09:54 < geertu> Time for Core chat? +09:55 < wsa> i think so +09:56 < geertu> ok diff --git a/wiki/Chat_log/20190606-mm-chatlog b/wiki/Chat_log/20190606-mm-chatlog new file mode 100644 index 0000000..059a252 --- /dev/null +++ b/wiki/Chat_log/20190606-mm-chatlog @@ -0,0 +1,132 @@ +Multimedia-chat-meeting-2019-06-06 + +10:05 < pinchartl> welcome to the multimedia meeting +10:05 < pinchartl> Topic 1.

The series is currently stalled due to on-going discussion with +10:15 < pinchartl> Laurent and Niklas and relatively low feedback from the rest of the +10:15 < pinchartl> V4L2 community. +10:15 < pinchartl> - Patch review +10:15 < pinchartl> Until next meeting: +10:15 < pinchartl> - Send next version of the CMM series +10:15 < pinchartl> Hope to meet the deadline for the v5.3 merge window (or is it late +10:15 < pinchartl> already?) +10:15 < pinchartl> Issues and blockers: +10:15 < pinchartl> - Consensus is hard to reach on v4l2-mux, stalling the work +10:15 < pinchartl> jmondi: any comment ? +10:16 < jmondi> I'm late for 5.3, rigth? +10:17 < pinchartl> I think the last chance would be tomorrow +10:17 < jmondi> ah +10:17 < jmondi> I don't think I could get your review on CMM for tomorrow, right? +10:17 < pinchartl> but there's no guarantee +10:17 < pinchartl> not unless you post the patches :-) +10:17 < jmondi> which assumes I should be able to resend today, which might not be impossible +10:18 < pinchartl> and one more version may be needed +10:18 < jmondi> ah you don't review not-posted patches? How lazy from you +10:18 < jmondi> indeed it might +10:18 < jmondi> pinchartl: should we try 5.3 or consider it late already? +10:18 < pinchartl> so there's no need to rush I think +10:19 < pinchartl> if you have spare cycles you can try, but it's getting late +10:19 < jmondi> a spare what? +10:19 < jmondi> :p +10:19 < pinchartl> :-) +10:19 < jmondi> I'll ping you if I'm able to resend today +10:19 < pinchartl> ok +10:19 < pinchartl> thank you +10:19 < pinchartl> * Kieran +10:19 < pinchartl> Since last meeting: +10:19 < pinchartl> - More investigation on partition algorithm phase +10:19 < pinchartl> New 'datasheet' implementation is still 'off' by x pixels. +10:19 < pinchartl> - Supported Laurent with DU group rework +10:19 < pinchartl> - Reviewed the LVDS dual-link mode series +10:19 < pinchartl> Until next meeting: +10:19 < pinchartl> - Continue digging on PA-phase +10:19 < pinchartl> Issues and blockers: +10:19 < pinchartl> - 'new' PA Phase is generating partitions that are not aligned correctly +10:19 < pinchartl> The 'dumbed down' implementation works, but following the datasheet +10:19 < pinchartl> procedure does not. Still not sure if that's a bug in the +10:19 < pinchartl> implementation, of if the algorithm provided by the datasheet just isn't +10:19 < pinchartl> creating the correct alignments. Needs extensive debug. +10:19 < pinchartl> kbingham: any comment ? +10:20 < kbingham> yes - its' painful :) Because I have low visibility of what the hardware does except for a 'yes/no' it's worked or hasn't :S +10:21 < kbingham> Otherwise status is correct :) +10:21 < pinchartl> really ? don't we know quite well what the hardware does ? +10:21 < kbingham> Do we know which pixels are being processed exactly and why it's unaligned when I expect it not to be? +10:22 < pinchartl> I don't see why it wouldn't be possible to find it out +10:22 < pinchartl> you can create specially crafted images to see what pixels are processed +10:23 < kbingham> Ok - lets work on something to do that next.

Status updates +09:31 < geertu> A) What have we done since last time: +09:31 < geertu> Marek cleaned up the QoS and PFC drivers in ATF, and moved them out of +09:31 < geertu> staging. +09:31 < geertu> Morimoto-san gained one year of wisdom. +09:31 < geertu> Shimoda-san worked on exporting BSDL files to Marek. +09:31 < geertu> Simon posted CMT DT binding patches for R-Car H3/M3-N/E3. +09:31 < geertu> Geert sent clk-renesas and sh-pfc pull requests for v5.3, posted an RFC +09:31 < geertu> to create DMA slave links in sysfs, and implemented the +09:31 < geertu> .determine_rate() callback for Z and SD clocks on R-Car Gen2/Gen3. +09:32 < geertu> B) What we plan to do till next time: +09:32 < geertu> Marek may look into DDR support in ATF. +09:32 < geertu> Shimoda plans to perform export control for BSDL files. +09:32 < geertu> Geert plans to send a second clk-renesas pull request for v5.3,enable +09:32 < geertu> SDRAM on RZA2MEVB, and start queuing Renesas arm/arm64 patches for v5.4. +09:33 < geertu> C) Problems we have currently: +09:33 < geertu> Simon wonders if +09:33 < geertu> Documentation/devicetree/.../renesas-memory-controllers.txt should be +09:33 < geertu> renamed. +09:33 < geertu> EOT +09:33 < geertu> Anything I missed? +09:34 < geertu> horms: Personally, I don't like the proposed renesas-memory,controllers.txt +09:34 < geertu> What about renesas,dbsc.text (.yaml ;-)? +09:35 < geertu> As of R-Mobile A1, all SoCs have a DDR DRAM controller, hence DBSC +09:35 < geertu> Up to SH-Mobile AG5, it was SBSC (SDRAM ...) +09:36 < horms> Sure, that is fine +09:36 < horms> this is exactly the kind of suggestion I was hoping for +09:37 < geertu> Good ;-) +09:38 < geertu> Topic 2.

And will send pull-requests, handle any changes requested for them, and handle any fixes for v5.3. +09:55 < horms> Geert, could I ask you to hold off until the pull requests are sent until you accept anything for v5.4. i.e. until next week? +09:55 < Marex> shimoda: btw. do you think we could release that ULCB CPLD USB control tool in public ? +09:55 < geertu> horms: Sure, I had planned to wait to Jul 1 +09:55 < geertu> s/to/until/ +09:56 < horms> That is up to you :) +09:56 < geertu> horms: Thanks for taking care during all these years! +09:56 < horms> Thanks, its been a pleasure. +09:56 < shimoda> Marex: it's depend on Renesas Europe side policy. I heard from Goda-san that Renesas Europe made the tool +09:57 < Marex> shimoda: but I made my own tool, which implements the same protocol, and I would like to release my own tool +09:57 < pinchartl> horms: do I understand correctly that our ways will part (at least on the Renesas side) after v5.3 ? should I assume this applies to Kaneko-san too ? +09:57 < Marex> shimoda: the renesas europe windoze-only tool is not interesting to me +09:57 < horms> I am handing over the maintenance role now, as Geert described. +09:57 < Marex> shimoda: but maybe I can ask Mr. Dege from Renesas Europe for approval and if he says yes, I can release my own tool ? +09:57 < horms> Kaneko-san and I plan to part ways with Renesas at the end of next quarter, i.e. end of Sept. +09:58 < Marex> horms: :-( +09:58 < pinchartl> horms: I'm sure we will still hear from you, one way or another :-) +09:58 < horms> Yes, I don't plan to stop existing alltogether +09:59 < geertu> horms: Will you join Microsoft? ;-) +09:59 < pinchartl> that is very good news, although not really a surprise :-) +09:59 < morimoto> Marex: windoze :) +09:59 < shimoda> Marex: oh, you made the tool. Yeah, i think if Mr Dege accepts you can release in public +09:59 < pinchartl> horms: thank you for the information. so I can expect more MM patches from you and Kaneko-san in Q3 \o/ +09:59 < horms> geertu: anything is possible! +09:59 < wsa> horms: thanks for all your maintenance work! +09:59 < jmondi> horms: I'm sorry to hear that, I hope you'll get around here anyhow after Q3 +10:00 < horms> patersonc: yes. I think most of the patching is complete and I owe you a ticket update. I'll try and get that to you soon so we can clafify what is/isn't outstanding +10:00 < patersonc> horms: Thank you! It's a shame you're stopping! +10:00 < Marex> shimoda: yep, I analyzed the protocol and made my own tool, which would be convenient for CI / testing +10:00 < patersonc> horms: Sure, no worries +10:00 < horms> patersonc: sorry, i meant that response for pinchartl. But thanks for yuor good wishes +10:01 < horms> patersonc: I can also send you a list of patches if you like, but it won't be very different to what is visible on patchwork +10:01 < patersonc> horms: :) no worries +10:01 < patersonc> horms: The system seems to work +10:01 < Marex> shimoda: i didn't want to circumvent you, hence I asked you about releasing the tool first, but if it's renesas europe who's in charge, I can ask for approval there +10:03 < geertu> Anything else to discuss? +10:03 < shimoda> Marex: thank you for asking first :) +10:03 < patersonc> Marex: Asking Dege is probably a good idea. +10:03 < Marex> shimoda: you're welcome +10:04 < patersonc> horms: What are your plans for the future? +10:04 < pinchartl> geertu: next meeting ? +10:04 < neg> flipping burgers at McDonalds ? +10:05 < pinchartl> now that many team members have seen their time allocation significantly reduced, I wonder if a bi-weekly meeting isn't too frequent +10:05 < kbingham> neg, That's automated now by IoT machines connected to the McNet :) +10:06 < morimoto> McNet :) +10:06 < wsa> pinchartl: i wondered about this, too, starting from Q4. But maybe Q3 is apropriate also? +10:07 < pinchartl> all additional tasks have been dropped, so we're down to 5 days a month on average for some of us +10:07 < pinchartl> and spending two mornings per months in meetings would be relative large in comparison +10:08 < geertu> so jul 4 is too early? +10:08 < kbingham> pinchartl, Indeed 4 hours of meetings per month is rather a large quantity of my renesas time budget +10:08 < geertu> jul 18 several people are in JP +10:09 < pinchartl> I think that on the multimedia side there will be very little to report by July the 4th +10:11 < geertu> For Core too, I think +10:11 < pinchartl> and the 18th will be during OSSJ, so not an option +10:11 < wsa> would that make July, 11th a candidate? I won't be available but we can handle IO stuff by mail, I'd think +10:12 < geertu> Jul 11 is fine for me +10:12 < morimoto> in 3 weeks pattern, 11th July -> 1st Aug -> 22th Aug... +10:13 < morimoto> or 4 weeks ? +10:13 < shimoda> or once per month? anyway Jul 11 is fine for me. +10:13 < pinchartl> we can try the 11th, but MM may need to be handled by e-mail too +10:14 < geertu> I don't want to be an exception ;-) +10:14 < geertu> we'll see +10:15 < geertu> Thanks for joining, and have a nice continued day! diff --git a/wiki/Chat_log/20190620-io-chatlog b/wiki/Chat_log/20190620-io-chatlog new file mode 100644 index 0000000..affed2d --- /dev/null +++ b/wiki/Chat_log/20190620-io-chatlog @@ -0,0 +1,98 @@ +09:04 < wsa> then, let's start the IO meeting +09:05 < wsa> first status updates: +09:05 < wsa> Status updates +09:05 < wsa> ============== +09:05 < wsa> A - what have I done since last time +09:05 < wsa> ------------------------------------ +09:05 < wsa> Geert +09:05 < wsa> : started looking into sh-sci tx_dma_len == 0 issue +09:05 < wsa> Kaneko-san +09:05 < wsa> : got "rcar_gen3_thermal: Update calculation" merged +09:05 < wsa> Shimoda-san +09:05 < wsa> : sent new versions of the SDHI & IOMMU patch series and a DMA documentation +09:05 < wsa> fix, sent USB patches about removing memcpy and an unbalanced flag and +09:05 < wsa> adding a limitation, reviewed USB binding documentation changes +09:05 < wsa> Simon +09:05 < wsa> : posted patches renaming bindings documentation to a common pattern +09:05 < wsa> Wolfram +09:05 < wsa> : converted i2c_new_dummy() calls and i2c_new_secondary_device() to new API, +09:05 < wsa> updated SDHI HS400 quirk patches and got them merged, worked on upporting +09:05 < wsa> SDHI manual calibration offsets, sent two treewide series fixing an awkward +09:05 < wsa> way to determine the adapter of an I2C client, smaller cleanup patches to the +09:05 < wsa> I2C + MFD + and media subsystems, reviewed Shimoda-san's next version of the +09:05 < wsa> SHDI IOMMU series + watchdog delay patches and some SDHI DTS patches, sent +09:05 < wsa> talk proposal for ELCE in Lyon +09:05 < wsa> B - what I want to do until next time +09:05 < wsa> ------------------------------------- +09:05 < wsa> Geert +09:05 < wsa> : wants to fix sh-sci tx_dma_len == 0 issue +09:05 < wsa> Shimoda-san +09:05 < wsa> : wants to keep working on the SDHI & IOMMU patch series, refactor the struct +09:05 < wsa> members of the usbhs driver, and keep an eye on upstream patches to avoid +09:05 < wsa> using virt_boundary_mask API +09:05 < wsa> Simon +09:05 < wsa> : wants to address review comments +09:05 < wsa> Wolfram +09:05 < wsa> : wants to continue working on upporting SDHI manual calibration offsets, +09:05 < wsa> upport more SDHI patches, continue working on I2C API changes, resend patch +09:05 < wsa> to handle watchdog handover from bootloader +09:05 < wsa> C - problems I currently have +09:05 < wsa> ----------------------------- +09:05 < wsa> Ulrich +09:05 < wsa> : didn't get a reply from Dave Miller about the RAVB MTU change implementation +09:05 < wsa> Wolfram +09:05 < wsa> : needs to delay the i2c_new_dummy() conversion because of a missing declaration +09:05 < wsa> in the i2c headers, and suffers from a lagging buildbot with lots of incomplete +09:05 < wsa> builds delaying the build tests of the I2C API changes +09:06 < wsa> uli__: what about just sending the patch and asking the questions again next to the patch description? +09:07 < wsa> horms: what happened to the "follow up on RAVB on E3/D3 Errata" task? +09:07 < wsa> any patches I missed there? +09:07 < horms> oops, let me add that back on the list +09:08 < uli__> wsa: do you suggest to re-send the patch as is, or to implement the rollback somehow and ask if that's ok? +09:09 < horms> I believe that the status is that we need to verify if setting tx timing delays in the phy is sufficient to miliate against the errata.

Thanks for the heads up +09:16 < Marex> in particular, Robin (from ARM) is "working" on a fix ... except Robin is even less responsive than Lorenzo +09:16 < wsa> Marex: Still, *I* missed the patch because of that. Just a small feedback. You can take it or not. +09:16 < Marex> funny thing is, now there are at least three SoCs which have the same problem (R-Car3, iMX8 and some broadcom SoCs), ARM claims to know about it, but does nothing +09:16 < Marex> wsa: ah, right +09:17 < wsa> Marex: let's see if we can chat with ARM people at Plumbers... +09:18 < wsa> geertu: I was thinking in a similar direction (critical clock) +09:18 < wsa> geertu: can we do something like: +09:18 < Marex> wsa: I am not going to plumbers +09:18 < wsa> if (clock_enabled_by_fw) clock_is_critical else clock_is_not_critical +09:18 < wsa> ? +09:19 < wsa> Marex: but I am :) +09:19 < Marex> wsa: and is Lorenzo or Robin ? +09:19 < Marex> wsa: those are the people you want to talk to +09:20 < wsa> I didn't find them on the speakers list +09:20 < wsa> but I'll keep my ears open if they are there... +09:23 < wsa> uli_: you are still at the RAVB MTU topic, or?
