-<wsa> so, welcome to the io meeting and here are the status updates: [16:54]
-<jmondi> 'morning everyone
-*** damm (~damm@l193216.ppp.asahi-net.or.jp) has joined channel #periperi
-<wsa> A - what have I done since last time
-<wsa> ------------------------------------
-<wsa> Geert
-<wsa> : fixed PHY Runtime PM in SH-ETH and related improvements for SMSC911X,
- added Falcon I2C EEPROM support
-<wsa> Niklas
-<wsa> : resent Gen3 timer patches, discussed V3U timer support
-<wsa> Shimoda-san
-<wsa> : added mmc aliases to Gen2/3 board files, investigated RPC-IF driver
- issues with BSP team, got some information about Gen3e
-<wsa> Ulrich
-<wsa> : sent atomic xfer support for i2c-rcar
-<wsa> Wolfram
-<wsa> : upstreamed V3U support for WDT, I2C, AVB0, SDHI, (H)SCIF for 5.12,
- investigated issues of AVB1-5 and RPC-IF on the V3U Falcon board, sent
- I2C core preparations for extended RECV_LEN sizes, improved I2C testunit
- with RECV_LEN testcase, moved already rejected patches from new BSP list
- to the non-target list, enabled WAIT_WHILE_BUSY and removed
- NON_REMOVABLE workaround for SDHI
-<wsa> B - what I want to do until next time
-<wsa> -------------------------------------
-<wsa> Geert
-<wsa> : wants to revise Falcon I2C EEPROM support
-<wsa> Niklas
-<wsa> : wants to figure out number of TSC nodes on V3U
-<wsa> Shimoda-san
-<wsa> : wants to continue to investigate SDHI driver's issues, collect more
- information about R-Car Gen3e, continue to develop R-Car S4 Ethernet
- driver [16:55]
-<wsa> Wolfram
-<wsa> : wants to pick up "logic analyzer via isolated CPU" work again,
- upstream CMT and TMU support for V3U, continue with extended RECV_LEN
- and its R-Car support, keep working on SDHI issues
-<wsa> C - problems I currently have
-<wsa> -----------------------------
-<wsa> None reported.
-<wsa> uli__: is this audio task a big one? Because I wanted to talk about a
- (hopefully) small RAVB task and am curious when I can get back to you?
-<uli__> that's not a problem
-<wsa> marex: what can we do to push the PCI L1 issue? Resend the patch?
- [16:56]
-<marex> wsa: probably disable L1 altogether
-<wsa> uli__: okay. so, i'll send you a mail with the details later. [16:57]
-<marex> wsa: and if someone needs it in the BSP, then there can be a
- downstream BSP patch which enables it for special cases where it might
- work OK
-<wsa> unconditionally? or just for some devices?
-<uli__> ok, thx
-<marex> wsa: but it seems for the generic case, which maintainers seems to
- care about, L1 is unusable
-<wsa> caring for the generic case sounds OK to me [16:58]
-<wsa> so we should disable it?
-<marex> the question is whether it is OK to just disable L1 altogether [16:59]
-<marex> right
-<marex> I guess we are out of options anyway
-<geertu> FTR, I got the interupt crash during PCIe resume on M3-W again
- earlier this week
-<wsa> shimoday: do you want to discuss this with the BSP team? [17:00]
-<marex> geertu: with what PCIe card and on which CPU core ?
-<geertu> As it's not easy to reproduce, it might be hard to see if disabling
- L1 helps
-<wsa> shimoday: if we should disable L1 on PCIe upstream because that's what
- the maintainers prefer
-<wsa> geertu: neg: thanks for testing the SDHI workaround removal patch. Much
- appreciated! [17:01]
-<geertu> marex: e1000e: Intel(R) PRO/1000 Network Driver
-<neg> I'm happy to see that quirk gone ;-)
-<wsa> neg: hopefully it will stay "gone" this time [17:02]
-<marex> wsa: BSP team can keep the patch which handles the link resume [17:03]
-<geertu> marex: No idea which CPU core
-<marex> wsa: although maybe it is just safer to turn off the L1 states in the
- BSP too
-<marex> geertu: do you have the backtrace ?
-<wsa> marex: exactly, maybe they want to support the generic case, too ;)
- [17:04]
-<wsa> okay, are there questions / comments from your side?
-<shimoday> wsa: i think we don't need to discus with BSP team because it's the
- maintainers prefer so BSP team will have no objection, i guess
-<wsa> i have one periject topic but I want this last
-<wsa> marex: can you prepare a patch then? [17:05]
-<marex> shimoday: do you happen to have customers that might need L1 link
- states ?
-<marex> for whatever reason
-<moriperi> geertu: sorry for my late response. Haha :) it is interesting way
- to increase for me :) [17:06]
-<geertu> marex: It's the same/similar one as
- https://lore.kernel.org/linux-pci/CAMuHMdX_ksY_AnaGyL0Z4HjUv72ndRM7XsRHkSKaBP7J-xmN1A@mail.gmail.com/
- [17:08]
-<marex> geertu: makes me wonder whether the spinlock in atf doesn't quite
- lock, uh [17:09]
-<geertu> marex: oh right, could be a bug in atf ;-)
-<marex> the entire gen3 L1->L0 code should be serialized
-<geertu> or better :-(
-<marex> hopefully not in such fundamental primitives [17:10]
-<shimoday> marex: hmm, it's a difficut thing. I don't have any idea how way is
- better for now...
-<wsa> I guess, at least for upstream, we should disable L1 [17:12]
-<wsa> BSP team then can decide if they want to pick it
-<wsa> so, for my periject topic [17:13]
-<shimoday> wsa: i agree
-<marex> wsa: I guess we have no other options anyway
-<wsa> let's wake some MM members first: kbingham[m] jmondi pinchartl neg :)
-<marex> and if BSP team needs the patch, it was posted [17:14]
-<kbingham> wsa, Hey I felt that
-<kbingham> :-)
-<wsa> some ppl said they want to add patches to the new "non-target" list
-<wsa> kbingham: good \o/
-<neg> zZzZ ;-) [17:15]
-<wsa> I propose that we add the reason in brackets '()' for now
-<wsa> Otherwise we start looking at the same patches again for patches which
- won't make it upstream but are still kept in the BSP [17:16]
-<wsa> I couldn't think of a better way to maintain this information for now
-<wsa> (please shoot if you can think of one)
-<shimoday> g [17:17]
-<shimoday> sorry, my dauther typed this 'g' ;)
-<geertu> wsa: You mean like
-<geertu> + - d8c1fb49de142298c345bd112fbad2b26cac9013 # arm64: dts: r8a77990:
- Change IPMMU-MM and IPMMU-caches order in DT (These are provisional
- patches. Please refer to https
- //patchwork.kernel.org/patch/10157459/)
-<wsa> It needed some yes
-<wsa> argh
-<wsa> yes
-<geertu> shimoday: Good. next important keys are "e", "e", "r", and "t" ;-)
- [17:18]
-<wsa> It needed some AWK scripts to port this information from good old
- periupport, but it moved quite some patches away
-<pinchartl> wsa: I don't wake up before 11:00 :-)
-<shimoday> geertu: :) [17:19]
-<wsa> pinchartl: This is why we discuss all important things before 11:00 ;)
-<geertu> wsa: What exactly do you mean by "add patches ... to the list"?
-<kbingham> is this for understanding why patches are rejected too? [17:20]
-<wsa> geertu: basically, if you add an entry to the non-target list
-<kbingham> in MM, we have rejected patches in the past, but of course BSP team
- still 'need/want' them, so they are there again in this latest bsp
- ticket.
-<geertu> wsa: patched moved from upport request, or also for random other
- patches we discover in the bsp?
-<wsa> kbingham: Right. And sometimes for years, so it may be forgotten if this
- could be upported or was already rejected. [17:22]
-<wsa> I had this with some RAVB patches which Simon back then already tried
- upstreaming but they were rejected upstream
-<shimoday> kbingham: sorry for lack information. the current bsp-41x list is
- from just the bsp, not thier want/need because
-<wsa> But I had to find this out digging through mail threads
-<shimoday> they are busy to make such "need/want" list for bsp-410...
-<shimoday> so, we need re-reject such patches again [17:23]
-<geertu> shimoday: Do they also plan to take our comments into account? E.g.
- [17:24]
-<geertu> spi: sh-msiof: Add MSIOF module clock changing processing for R-Car
- Gen3 (Proposing 'N' Should use "assigned-clocks" and
- "assigned-clock-rates" in board DTS file that actually uses MSIOF)
-<wsa> and to avoid digging through old mails, I'd like to collect the
- information somehow
-<wsa> geertu: that might be another benefit [17:25]
-<geertu> wsa: OK, I'll update the recent changes I made to
- bsp-41x-non-target.yaml
-<wsa> It may not be the best format; I guess updating from one BSP list to the
- next one is probably still some strange scripting [17:26]
-<shimoday> geertu: what is "into account" mean?
-* jmondi catches up with the discussion
-<wsa> but as people want to start filling the "non-target" list, it might be a
- start at least
-<geertu> shimoday: replace the BSP way by the suggestion in the comment
-<jmondi> wsa: geertu: was the sweep you made to the ticket a manual process or
- do you have scripts that identify patches that were rejected and
- re-purposed in the new ticket ? [17:27]
-<geertu> jmondi: the one marked (patch-id) and (summary) where done by some
- half-baked scripting [17:28]
-<wsa> jmondi: for porting the comments from periupport, I wrote scripts to
- identify patches based on $subject
-<geertu> run "git path-id --stable" and "git log --oneline" on all commits
- upstream and in the BSP, and look for matches
-<geertu> s/path-id/patch-id/ [17:29]
-<geertu> s/where/were/
-<jmondi> wsa: geert: I see, everyone has its own method it seems [17:30]
-<geertu> jmondi: It was similar to what I do for my regular "Auto-update
- sweep", which considers patch-id and lore link
-<wsa> jmondi: well, the port from periupport is done now [17:31]
-<wsa> now it is about porting from one bsp-list to the next
-<jmondi> yeah sure, I was thinking about moving to one BSP list to anther, and
- mostly for future tickets
-<jmondi> anyway, thanks, it's not a huge number of patches, and some scripting
- + some manual verification should do [17:32]
-<wsa> hopefully so
-<wsa> when backporting upstream patches, BSP team adds lines like
- "cherry-picked from: ..." to the description [17:33]
-<wsa> that would be nice for cherry-picking old BSP patches, too, I'd think
- [17:34]
-<wsa> if the BSP team is up for it
-<wsa> that said, matching on $subject worked quite well
-<wsa> OK, I think we can close this now? [17:35]
-<wsa> and move to core?
-<jmondi> wsa: so we can match on the 'cherry-picked from' ?
-<geertu> wsa: Indeed, Shimoda-san did that in 4d75bd75ef222375 ("linux:
- bsp-41x: Move cherry picked commits to non target")
-<jmondi> between tickets I mean
-<wsa> jmondi: yes
-<geertu> jmondi: If the cherry-picked points to a commit in upstream or
- stable.
-<geertu> I.e. if "git tag --contains <sha1> v5.11" prints v5.11 [17:36]
-<geertu> (stable needs more checks, as there are more trees) [17:37]
-<jmondi> oh I thought wolfram was suggesting, in case the patch has not been
- upstreamed, to point to the commit id in the previous bsp ticket
-<jmondi> so we can easy get to the status assigned to the patch in the
- previous ticket [17:38]
-<geertu> Oops, I missed that detail
-<jmondi> anyway, please move to core, I don't want to continue interrupting
- the meeting
-<geertu> So yes, then we have to look at what cherry-picked points to for
- sure!
-<wsa> geertu: ready? [17:39]
-<geertu> wsa: it can point to a commit in upstream, stable, or another BSP
- version.
-<wsa> geertu: right [17:40]
-<geertu> I believe a new BSP is created by rebasing, not by cherry-picking?
- (yes, technically, it's the same)
-<wsa> I wouldn't want to solely rely on "cherry-picked from" anyhow [17:42]
-<geertu> agreed
-<wsa> It is nice if the BSP teams helps
-<wsa> but we should be able to act independently from that IMO [17:43]
-<wsa> so, core now? [17:44]

+09:40 < jmondi> anyway, thanks, it's not a huge number of patches, and some scripting + some manual verification should do
+09:41 < wsa> hopefully so
+09:41 < wsa> when backporting upstream patches, BSP team adds lines like "cherry-picked from: ..." to the description
+09:42 < wsa> that would be nice for cherry-picking old BSP patches, too, I'd think
+09:42 < wsa> if the BSP team is up for it
+09:43 < wsa> that said, matching on $subject worked quite well
+09:43 < wsa> OK, I think we can close this now?
+09:43 < wsa> and move to core?
+09:43 < jmondi> wsa: so we can match on the 'cherry-picked from' ?
+09:43 < geertu> wsa: Indeed, Shimoda-san did that in 4d75bd75ef222375 ("linux: bsp-41x: Move cherry picked commits to non target")
+09:43 < jmondi> between tickets I mean
+09:43 < wsa> jmondi: yes
+09:44 < geertu> jmondi: If the cherry-picked points to a commit in upstream or stable.
+09:45 < geertu> I.e. if "git tag --contains <sha1> v5.11" prints v5.11
+09:45 < geertu> (stable needs more checks, as there are more trees)
+09:45 < jmondi> oh I thought wolfram was suggesting, in case the patch has not been upstreamed, to point to the commit id in the previous bsp ticket
+09:46 < jmondi> so we can easy get to the status assigned to the patch in the previous ticket
+09:46 < geertu> Oops, I missed that detail
+09:46 < jmondi> anyway, please move to core, I don't want to continue interrupting the meeting
+09:46 < geertu> So yes, then we have to look at what cherry-picked points to for sure!
+09:47 < wsa> geertu: ready?
+09:47 < geertu> wsa: it can point to a commit in upstream, stable, or another BSP version.
+09:48 < wsa> geertu: right
+09:48 < geertu> I believe a new BSP is created by rebasing, not by cherry-picking? (yes, technically, it's the same)
+09:50 < wsa> I wouldn't want to solely rely on "cherry-picked from" anyhow
+09:50 < geertu> agreed
+09:50 < wsa> It is nice if the BSP teams helps
+09:51 < wsa> but we should be able to act independently from that IMO
+09:52 < wsa> so, core now?
+09:53 < geertu> yes! (I/O was going to be short ;-)
