+11:06 < pinchartl> Issues and blockers: None
+11:06 < pinchartl> horms: any comment ?
+11:06 < neg> I'm back just in time it seems :-) No comment
+11:07 < pinchartl> neg: welcome back !
+11:07 < neg> thanks, sorry for the conflict
+11:08 < horms> pinchartl: none, I had issues with E3 Audio. Morimoto's guidance helped me fix them. No problems at this time
+11:08 < horms> Let me know if you want any upporting done :)
+11:08 < morimoto> horms: good to know :)
+11:08 < pinchartl> sure :-)
+11:09 < pinchartl> I'm marking patches as 'MM upstreaming candidates' in periupport, feel free to pick them if you want
+11:09 < pinchartl> there's nothing particularly urgent so far
+11:09 < pinchartl> the pinctrl and DT integration commits are good candidates for non-urgent upporting
+11:11 < pinchartl> Ulrich isn't here, did he say he would miss this meeting ? the last I heard was "prepare for stay in the Philippines until Dec 10" two weeks ago, but I don't know if that means holidays or working under the sun
+11:11 < wsa> pinchartl: same question here
+11:11 < pinchartl> wsa: I thus assume you don't know the answer :-)
+11:11 < pinchartl> geertu: damm: any info ?
+11:12 < geertu> pinchartl: I don't know.
+11:12 < pinchartl> ok
+11:13 < geertu> His "tips-and-tricks to use free Wifi effectively" may not be applicable to the Philippines ;-)
+11:13 < pinchartl> :-D
+11:13 < pinchartl> on the topic of periupport
+11:14 < pinchartl> morimoto: in the bsp370 ticket file, you have marked lots of commits with a reference to previous BSP releases
+11:14 < pinchartl> if I update a commit in the v4.14 file, should I update the corresponding commit in bsp370, or leave the reference ?
+11:15 < morimoto> uhm
+11:15 < morimoto> Basically there are no conflict commits between v4.14 vs bsp370
+11:15 < morimoto> But, you had it ?
+11:16 < pinchartl> it's not a matter of conflicts
+11:16 < pinchartl> for instance
+11:16 < morimoto> sorry, not conflicts, duplicate
+11:16 < pinchartl> commit 543637cb084774608dc67144be0ac0ae9e534350
+11:16 < pinchartl> is
+11:16 < pinchartl> in bsp370
+11:16 < pinchartl> N,543637cb084774608dc67144be0ac0ae9e534350|requested upport with f7cac36f6d7862f93a12cfb8d4d0d9b47f132179 of BSPv3.6.0
+11:17 < pinchartl> what should I do with that ?
+11:17 < pinchartl> not touch it because it's marked N ?
+11:17 < morimoto> Ahh, please ignore "N" commit.
+11:17 < morimoto> Mainly, we need latest ticket only. so, bsp370
+11:18 < morimoto> is important to Renesas
+11:19 < pinchartl> hmmmm...
+11:19 < wsa> Yet, 'N' is all the Ebisu upporting for example (enablement of SCIF, I2C, for example)
+11:19 < wsa> we surely want that, or?
+11:19 < morimoto> on bsp370 ?
+11:20 < morimoto> pinchartl: sorry, what is wrong ?
+11:20 < pinchartl> another example
+11:20 < pinchartl> in bsp370
+11:20 < pinchartl> N,068d08088b263a2c037656ea9668f8bb2be3d046|requested upport with 6ea68fc0ce880bdfa511b45b8e7ace42303c71e5 of BSPv3.6.0
+11:21 < pinchartl> and in v4.14
+11:21 < pinchartl> M,6ea68fc0ce880bdfa511b45b8e7ace42303c71e5
+11:21 < pinchartl> have you marked it as N in bsp370 because you expect it to be upported from v4.14 ?
+11:22 < morimoto> Oops, I misunderstood...
+11:23 < morimoto> BSP team is thinking that they avoid duplicate request
+11:23 < morimoto> It seems
+11:24 < morimoto> We need to avoid N, and care about M/H on both v4.14 and bsp370
+11:24 < morimoto> Renesas inside doesn't matter about "N", but counting how many patch are upported
+11:24 < morimoto> (= for L/M/H)
+11:25 < pinchartl> ok
+11:25 < horms> Ok, so for KPI N is irrelevant
+11:25 < horms> I asked this a bit earlier, but is there a plan to produce bsp380 ?
+11:25 < pinchartl> wouldn't it have been better to mark the commit as N in v4.14 and as M bsp370 ?
+11:25 < pinchartl> that way the latest BSP ticket file would contain most of the work to be done
+11:26 < morimoto> pinchartl: it is good idea. thanks
+11:26 < pinchartl> similarly to when you post a v2 of a patch, v1 is marked as superseded and everybody forgets about it
+11:27 < pinchartl> so how should we handle this ? does anyone have a magic script to reconcile everything ? :-)
+11:28 < morimoto> I can't use magic :(
+11:28 < horms> is it against company policy?
+11:29 < morimoto> horms: is it question to me ?
+11:29 < horms> morimoto: sorry, it was a joke about magic.
+11:29 < pinchartl> I'll try to write a script to handle this
+11:30 < pinchartl> morimoto: thanks for the feedback
+11:30 < morimoto> horms: yeah, it is joke my side too :)
+11:30 < pinchartl> Topic 2. Discussions
+11:30 < horms> morimoto:)
+11:30 < pinchartl> Marex: you've requested a discussion about FCNL
+11:30 < pinchartl> we've already discussed the topic, is there something you would like to add ?
+11:32 < morimoto> pinchartl: Marex: I think you had question about it to BSP team, but 1) they don't know detail, because it is used by 3rd party 2) related guy already go back to home today. So please send me question mail, I can forward it to BSP/3rd party, and feedback to you.
+11:34 < wsa> horms: what is KPI?
+11:34 < pinchartl> while waiting for Marex, does anyone have any other topic they would like to discuss ?
+11:34 < pinchartl> wsa: Key Performance Indicator
+11:34 < Marex> pinchartl: let
+11:34 < wsa> thanks
+11:35 < morimoto> wsa: KPI = key performance indicator
+11:35 < Marex> pinchartl: let's postpone FCNL until we have DT support in ATF ? :)
+11:35 < Marex> pinchartl: and until the FCNL is sorted out in Linux too ?
+11:35 < neg> I would only like to ask if anyone wish me to prepare or bring something specail to facilitate MM work during ELCE. As we talked about E3 testing maybe there is something else?
+11:35 < Marex> morimoto: would Takuya Sakata-san be willing to discuss ATF with me ? :)
+11:36 < morimoto> hmm.. I don't know him...
+11:36 < morimoto> discuss by what ? mail ?
+11:36 < Marex> morimoto: jupp, email
+11:36 < Marex> morimoto: I'd like to send him some ATF patches
+11:36 < Marex> morimoto: OK, I'll just send him the patches :)
+11:37 < wsa> pinchartl: I think I can brush up my 'transfer upporting info from ticket x to ticket y' script to transfer the old prio if the new one is 'N'
+11:37 < morimoto> Marex: OK, please do
+11:37 < pinchartl> Marex: but please keep FCNL support in your ATF patch series
+11:38 < Marex> pinchartl: but the bindings are not fleshed out yet and I don't want them to become ABI
+11:39 < pinchartl> wsa: that would be nice, as I was thinking about writing such a script :-) my idea is roughly if (new prio == N and comment == reference to old commit) { copy old commit prio and comment to new commit; set old prio to N and comment to reference new commit }
+11:39 < pinchartl> wsa: do you think you could do that ?
+11:39 < pinchartl> it would be useful to commit the script to the repo too
+11:40 < pinchartl> Marex: you don't have to upstream it yet, but I'd like the patches to be included in the series, in order to make sure that the proposal will work
+11:40 < pinchartl> would that be OK with you ?
+11:40 < Marex> I do keep the patch, it's not like I threw it away
+11:40 < wsa> pinchartl: I'll try
+11:41 < wsa> and let you all know :)
+11:41 < pinchartl> Marex: thanks :-)
+11:41 < pinchartl> wsa: thanks
+11:41  * Marex wonders if we can generate FDT at compile time ... :-)
+11:41 < Marex> I guess we can
+11:41 < pinchartl> Marex: interesting idea
+11:41 < Marex> pinchartl: we can ...
+11:42 < pinchartl> so if there's no more discussion topic,
+11:42 < pinchartl> Topic 3. Additional Tasks for Q4
+11:42 < pinchartl> The following additional tasks have been submitted and approved, they are now going through the usual process. SoWs should be sent in the near future, with a 12/M due date.
+11:42 < pinchartl> * ADV748x Dynamic Routing (Jacopo)
+11:42 < pinchartl> * M3-N rotation bug fix (Kieran)
+11:42 < pinchartl> * Fix RGB output routing on D3 and E3 (Laurent)
+11:42 < pinchartl> * Upporting and addition of pixel format (Niklas)
+11:42 < geertu> Marex: if we know the parameters at compile-time, we can
+11:42 < pinchartl> any question/comment ?
+11:43 < neg> Looks good to me
+11:43 < Marex> geertu: but then why should it be part of ATF ? We can have the bootrom load the DT
+11:43 < jmondi> fine with me, thanks
+11:44 < kbingham> Sounds OK to me.
+11:44 < geertu> Marex: ATF programs the DRAMC
+11:44 < Marex> geertu: but the programming of that is given to ATF by the integrator
+11:44 < pinchartl> next, Topic 4. Face to Face Meeting in Edinburgh
+11:44 < Marex> geertu: it's literally a few C macros
+11:45 < pinchartl> I don't think we should spend time discussing status updates there, as there will not be much
+11:45 < pinchartl> are there any particular topic that team members would like to discuss face to face ?
+11:45 < kbingham> There's going to be a v4l2 codec meeting at ELCE
+11:45 < pinchartl> correct
+11:46 < kbingham> But from previous attempts at suggesting codec work - I assume renesas has little interest?
+11:46 < neg> Potential plan and for unified DU and VIN test suite :-)
+11:46 < kbingham> ^ Plus automated testing, + unit testing :)
+11:47 < morimoto> interesting topic for test team
+11:47 < pinchartl> kbingham: I wouldn't expect Renesas to have any new interest all of a sudden, but if you can think about a strategy to make them change their mind, I'd love to discuss that
+11:50 < kbingham> pinchartl, well that depends on what their concerns are regarding the codecs. 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. Next Meeting
+11:55 < pinchartl> two weeks from now ?
+11:56 < pinchartl> three weeks from now ?
+11:56 < pinchartl> four weeks from now ? :-)
+11:56 < pinchartl> geertu: wsa: ^^
