+10:37 < pinchartl> jmondi: any comment ?
+10:38 < jmondi> not really
+10:38 < jmondi> just catching up with backlog curently
+10:38 < pinchartl> regarding conference planning, let's discuss that towards the end of the meeting
+10:39 < pinchartl> * Kieran
+10:39 < pinchartl> Since last meeting:
+10:39 < pinchartl> - Reviewed/supported "[PATCH] v4l: vsp1: Fix deadlock in VSPDL DRM pipelines"
+10:39 < pinchartl> - D3 DU/Interlaced investigations
+10:39 < pinchartl> - Chasing GMSL. Need to rebase Sakari's VC work.
+10:39 < pinchartl> - VSP1 1x1 pixel issue
+10:39 < pinchartl> - DU/interlaced v6. Accepted by Maintainer at last \o/
+10:39 < pinchartl> - GMSL for-renesas driver pull request (finally)
+10:39 < pinchartl> - GMSL v2 public posting (sans VC)

+10:39 < pinchartl> - DU/D3 interlaced restrictions
+10:39 < pinchartl> Issues and blockers: None
+10:39 < pinchartl> kbingham: you also mentioned two weeks ago that you would look at reposting the VSP pending patches series (partition algo & writeback)
+10:39 < pinchartl> is that still planned ?
+10:39 < kbingham> The need to rebase Sakari's VC work was wrong/removed. I posted GMSL without VC
+10:40 < kbingham> Hrm ... I rebased writeback ...
+10:40 < kbingham> I guess I haven't included it in my notes as I haven't posted it...
+10:40 < pinchartl> should I add both to the todo list ?
+10:41 < kbingham> Yup.
+10:41 < pinchartl> thanks
+10:41 < pinchartl> * Laurent
+10:41 < pinchartl> Since last meeting:
+10:41 < pinchartl> - Patch review
+10:41 < pinchartl> - Got VSP interlaced support merged (DU will follow in v4.20)
+10:41 < pinchartl> - Additional tasks preparation
+10:41 < pinchartl> Until next meeting:
+10:41 < pinchartl> - Patch review
+10:41 < pinchartl> - D3/E3 DU LVDS PLL upstreaming
+10:41 < pinchartl> - Get GMSL patches merged
+10:41 < pinchartl> Issues and blockers: None
+10:42 < pinchartl> any comment from anyone?
+10:42 < jmondi> that's a big one, and I don't want to resume the process/periject discussion
+10:43 < jmondi> but how would you prefer to receive periupport updates? patches are ok? do you handle that by yourself looking at patches sent to mailing list?
+10:43 < pinchartl> jmondi: patches are best
+10:44 < pinchartl> as that's easiest to handle for me
+10:44 < jmondi> I sent a few updates to periupport not "for inclusion"  but as a matter of keeping track of which BSP patches we were more or less working with
+10:44 < pinchartl> otherwise I do it manually (but not very often)
+10:44 < jmondi> I think there needs to be some work from your side too to apply those patches, I'm wondering how to minimize that
+10:45 < jmondi> I feel like bulk updates do not work that well
+10:45 < pinchartl> ideally we would update it in real time as soon as we get something merged upstream
+10:46 < pinchartl> but in reality I don't think this will ever happen
+10:46 < jmondi> I'm thinking for each BSP whose status changed, a single patch to periupport you can then squash, with a referce to the series/task that upports/obsolates them
+10:46  * kbingham goes to check periupport du/interlaced lines  :)
+10:46 < pinchartl> same problem as filling timesheets really, how often is that done at the end of the week when we can't remember what we've done and have to dig up, knowing perfectly well it would be easier to do it in realtime ?
+10:46 < jmondi> because we rarely have a 1 to 1 match
+10:48 < pinchartl> I don't really see a good solution to this problem if we don't enforce updates through process and tooling
+10:48 < pinchartl> so at the moment, bulk patches is likely the best I can hope for
+10:49 < pinchartl> unless someone else has a better advice ?
+10:50 < kbingham> chmod g+w periupport ?
+10:50 < pinchartl> kbingham: we'll still need review, based on my experience with patches that Jacopo posted before
+10:50 < jmondi> kbingham: I'm not sure we all should push to periupport
+10:51 < jmondi> kbingham: in the last week I would have screwed up myself only a few times
+10:51 < kbingham> Ok :)
+10:52 < pinchartl> * Morimoto-san
+10:52 < pinchartl> Since last meeting:
+10:52 < pinchartl> - RSND multi DAI support
+10:52 < pinchartl> Until next meeting:
+10:52 < pinchartl> - Continue multi DAI support and post patches
+10:52 < pinchartl> Issues and Blockers: None
+10:52 < pinchartl> morimoto: any comment?
+10:54 < pinchartl> seems not :)
+10:54 < pinchartl> * Niklas
+10:54 < pinchartl> Since last meeting:
+10:54 < pinchartl> - [PATCH] rcar-csi2: update stream start for V3M
+10:54 < pinchartl> - [PATCH] v4l2-ctl: add support for SUBDEV_{G_STD,S_STD,QUERYSTD}
+10:54 < pinchartl> - Reviewed V3H  VIN and CSI-2 patches.
+10:54 < pinchartl> Until next meeting:
+10:54 < pinchartl> - Finish last VC patch for adv748x use-case.
+10:54 < pinchartl> - Post VC series.
+10:54 < pinchartl> - Post held back VIN format patches.
+10:54 < pinchartl> Issues and blockers: None
+10:54 < pinchartl> neg: any comment ? I know you might be lurking :-)
+10:55 < neg> no comment :-)
+10:55 < pinchartl> :-)
+10:55 < pinchartl> * Simon (Kaneko-san)
+10:55 < pinchartl> Since last meeting:
+10:55 < pinchartl> - D3 audio support upport
+10:55 < pinchartl> Until next meeting:
+10:55 < pinchartl> - Continue D3 audio support upport
+10:55 < pinchartl> - Testing M3-N audio support
+10:55 < pinchartl> Issues and blockers: None
+10:55 < pinchartl> horms: any comment?
+10:56 < horms> hi pinchartl
+10:56 < morimoto> pinchartl: sorry for delay: no comment
+10:56 < horms> The D3 audio backport looks good. We have access to a machine in Magnus's lab. And it has looback audio present. So that part can proceed.
+10:56 < pinchartl> morimoto: no issue
+10:56 < horms> s/D2/M3-N/
+10:57 < horms> I think upporting for M3-N can also proceed as I unblocked Kaneko-san regarding a BSP patch he couldn't locate
+10:57 < horms> But going might be a bit slow due to holiday activities
+10:57 < horms> No other comments :)
+10:57 < pinchartl> no worries about that :)
+10:57 < pinchartl> thanks
+10:57 < pinchartl> * Ulrich
+10:57 < pinchartl> Since last meeting:
+10:57 < pinchartl> - Prototyping LVDS PLL support on D3
+10:57 < pinchartl> Until next meeting:
+10:57 < pinchartl> - Finish prototyping LVDS PLL support on D3
+10:57 < pinchartl> Issues and blockers: None
+10:57 < pinchartl> uli_: any comment ?
+10:57 < uli_> nope
+10:58 < pinchartl> I got a question though, do you think you will be able to post a functional prototype by the 15th ?
+10:58  * geertu starts looking for all "remove before leaving on holidays" tags...
+10:58 < uli_> i think so
+10:58 < pinchartl> great, thanks
+10:59 < pinchartl> Topic 2. Additional Multimedia Tasks for Q3
+10:59 < pinchartl> additional tasks are out now, you should all have received them
+10:59 < pinchartl> please let me know if there's any issue
+10:59 < pinchartl> Topic 3. Periperi Meetings
+11:00 < pinchartl> it looks like all of us will go to Edinburgh
+11:00 < pinchartl> and that the best day for a global meeting will be Friday the 26th
+11:00 < pinchartl> is that correct ?
+11:01 < morimoto> no topics yet ?
+11:01 < pinchartl> morimoto: do you mean for the meeting agenda ?
+11:01 < morimoto> yes
+11:02 < pinchartl> I would personally like to discuss the development process and its relationship with periject. by the time of the conference I certainly hope we will bee able to reach a consensus
+11:03 < pinchartl> and if we complete that topic earlier, then we'll have more time to discuss other topics :-)
+11:03 < morimoto> OK, F2F is nice for it :)
+11:03 < pinchartl> we can lock the room until we reach an agreement :-D
+11:03 < wsa> morimoto: I am very glad to hear that you will come to ELCE! :D
+11:04 < morimoto> hehe :)
+11:04 < morimoto> I'm looking forward to see you guys again !
+11:04 < neg> wsa: are you OK with moving SDHI hacking day so it won't collide with the V4L2 meeting?
+11:04 < wsa> someone else from JapaPERI coming?
+11:05 < kbingham> I guess we aught to do a haggis and whisky evening while we're there :)
+11:05 < Marex> neg: can I join the SDHI hacking day ?
+11:05 < Marex> wsa: ^
+11:05 < morimoto> wsa: I and Ito-san maybe. No Magnus, No shimoda-san
+11:06 < Marex> no morimoto no life (TM) ?
+11:06 < wsa> morimoto: I see. Then you have to take Magnus place when boozing with Niklas :D
+11:06 < Marex> morimoto: looking forward to seeing you again in the UK :)
+11:06 < wsa> Marex: in general, sure yes, very welcome
+11:06 < morimoto> Marex: you are correct :)
+11:07 < morimoto> wsa: :)
+11:07 < Marex> wsa: thanks ... I seem to be doing something with SDHI in U-Boot on my own and it seems you and neg are solving similar problems in Linux ... I think it makes sense to sync up
+11:07 < wsa> not decided yet, if we do a full hacking day on saturday (but we won't have the flat anymore then), or spread it over the days (doesn't sound likely)...
+11:07 < morimoto> Marex: me to
+11:07 < wsa> Marex: makes perfect sense
+11:08 < Marex> morimoto: :))
+11:08 < wsa> Marex: although some of the sync should happen before ELCE by mail ;)
+11:08 < Marex> wsa: fine by me
+11:08 < wsa> or we do the SDHI hacking in Dunbar at the coast :D
+11:09 < wsa> at weekends
+11:09 < pinchartl> do we have an agreement for the 26th then ?
+11:09 < wsa> yes
+11:09 < wsa> SDHI hacking involves less people, so let's move this around
+11:09 < neg> works for me
+11:09 < wsa> since everyone else has time on Friday for the "big" meeting
+11:09 < horms> fewer people
+11:10 < wsa> oh!
+11:10 < pinchartl> on the multimedia side, I still want to organize a code camp
+11:10 < pinchartl> KR and XDC have been mentioned before
+11:10 < pinchartl> but I think LPC could be a better option
+11:11 < Marex> pinchartl: who's going to LPC ? did you submit anything ?
+11:12 < wsa> Marex: did you plan to stay the weekend after ELCE?
+11:12 < pinchartl> I haven't submitted anything
+11:12 < pinchartl> but I will go
+11:12 < kbingham> I plan to go to LPC
+11:13 < pinchartl> neg: so do you I think?
+11:13 < pinchartl> jmondi: will you be there?
+11:13 < pinchartl> uli_: how about you?
+11:14 < uli_> not at lpc
+11:15 < pinchartl> the plan would be to spend at least 3 days together
+11:15 < pinchartl> so likely the week before or after the conference
+11:16 < neg> If there is MM meeting at LPC I will go if not I stay home
+11:17 < pinchartl> ok
+11:17 < pinchartl> that's it for me for today. any other topic that we should discuss ?
+11:18  * morimoto good timing for me. I need to go back to home soon
+11:20 < morimoto> sorry, but I will quit
+11:20 < morimoto> bye-bye, enjoy your summer vacation
+11:21 < pinchartl> as there's no other topic let's adjourne this meeting
+11:21 < pinchartl> thank you all for attending
