+10:18 < pinchartl> welcome to the multimedia meeting
+10:18 < pinchartl> Topic 1. Status Check for the Multimedia Tasks
+10:18 < pinchartl> * Jacopo
+10:18 < pinchartl> Since last meeting:
+10:18 < pinchartl> - Restarted work on CMM
+10:18 < pinchartl> Ezequiel (Collabora) is developing a very similar feature for Rockchip,
+10:18 < pinchartl> and Sean's review on his patches will be taken into account for CMM.
+10:18 < pinchartl> Until next meeting: N/A
+10:18 < pinchartl> Issues and blockers: None
+10:18 < pinchartl> jmondi: any comment ?
+10:19 < jmondi> pinchartl: yes, quick one
+10:19 < jmondi> Ezequiel has moved all their gamma LUT handing to atomic_enable/begin
+10:20 < jmondi> Sean suggested that, and that removes the need to restore the color_management_changed flag after suspend as we do now
+10:20 < jmondi> I plan to do the same for CMM, but before going down that path I would like your opinion there
+10:20 < pinchartl> that seems wrong, the gamma LUT should be modifyable at runtime
+10:20 < jmondi> [PATCH v4 0/3] RK3288 Gamma LUT
+10:20 < pinchartl> why did they do that ?
+10:21 < jmondi> I'm not sure I did completely understood Sean's reply to v3
+10:21 < jmondi> I asked eze too yesterday, but then I had to run
+10:21 < pinchartl> could you check it with them ? please raise the issue of modifying the gamma table at runtime
+10:22 < jmondi> also, they moved everything to crct_enable/begin, while we had that in the commit_tail helper
+10:22 < jmondi> so the CMM would be set per-CRTC ?
+10:22 < pinchartl> to determine if it has to be supported (and if not, why, and where that is documented)
+10:22 < jmondi> I will keep pressing Ezequiel on that
+10:22 < jmondi> it's fun how many corner cases we're hitting with CMM
+10:22 < jmondi> well, fun..
+10:23 < pinchartl> it doesn't matter if it's set in the atomic tail handler or the CRTC operations, that's not relevant
+10:23 < pinchartl> what is relevant is if modifying the gamma LUT without a modeset needs to be supported
+10:23 < jmondi> ah well, no
+10:23 < jmondi> we do
+10:23 < jmondi> for_each_old_crtc_in_state
+10:24 < jmondi> so we go through each crtc anyhow
+10:24 < pinchartl> sure, we have to as gamma tables are per CRTC
+10:24 < jmondi> indeed, my bad, I got confused
+10:25 < jmondi> I'll try to know more
+10:25 < pinchartl> so please check with them before changing anything, and please let me know
+10:25 < pinchartl> thank you
+10:25 < jmondi> you'll be cc-ed
+10:26 < pinchartl> ok. I don't plan to participate in the discussion though, please make sure to drive it
+10:26 < pinchartl> next, Kieran, who is AWOL due to having a new baby
+10:27 < pinchartl> (what wouldn't people do to have a few weeks of off ? :-))
+10:27 < pinchartl> * Laurent
+10:27 < pinchartl> Since last meeting:
+10:27 < pinchartl> - CMM & other patches review
+10:27 < pinchartl> - Attended XDC (X.Org Developer's Conference)
+10:27 < pinchartl> Discussed, among other topics, a new kernel API for cameras,
+10:27 < pinchartl> interoperability between displays and cameras, fences for V4L2, buffer
+10:27 < pinchartl> allocator API with constraint resolution, ...
+10:27 < pinchartl> Until next meeting:
+10:27 < pinchartl> - CMM review to finish the upstreaming
+10:27 < pinchartl> - DU group refactoring
+10:27 < pinchartl> - Attending ELC-E (with V4L2 workshop)
+10:27 < pinchartl> Issues and Blockers: None
+10:27 < pinchartl> any question ?
+10:27 < pinchartl> * Morimoto-san
+10:27 < pinchartl> Since last meeting:
+10:27 < pinchartl> - ALSA SoC framework cleanup
+10:27 < pinchartl> Posted patches have been accepted, posted next set.
+10:27 < pinchartl> - ALSA SoC small bug fixes
+10:27 < pinchartl> Until next meeting:
+10:27 < pinchartl> - Continue progressing cleanup patches
+10:27 < pinchartl> Issues and Blockers:
+10:27 < pinchartl> - Can't test Intel-related changes
+10:27 < pinchartl> Some of the cleanup patches are related to an Intel-specific features.
+10:27 < pinchartl> The code is compile-tested only due to lack of a test platform.
+10:27 < pinchartl> - Large number of cleanup patches to upstream
+10:27 < pinchartl> ALSA SoC is too complex today, hence the need for a large cleanup, with
+10:27 < pinchartl> more than 500 local patches still pending. The next step will focus on
+10:27 < pinchartl> soc-pcm that supports flexible CPU/codec connections, and this area is
+10:27 < pinchartl> too complex.
+10:27 < pinchartl> morimoto: any comment ?
+10:28 < morimoto> Intel said that they are using Github to test hardware
+10:28 < morimoto> He can test it
+10:29 < pinchartl> ? how does that work ?
+10:29 < morimoto> I'm not sure detail, but if he push patches to Github,
+10:29 < morimoto> test script (?) works automatically
+10:30 < morimoto> Some magical machine is working
+10:30 < pinchartl> I would have assumed them to use gitlab for self-hosted CI integration
+10:30 < morimoto> And it seems my patches were OK
+10:30 < pinchartl> that's good news :-)
+10:30 < pinchartl> so it's not an issue anymore ?
+10:30 < morimoto> yes :)
+10:30 < morimoto> Yeah, thanks
+10:31 < pinchartl> thank you
+10:32  * pinchartl wonders if ALSA SoC cleanup is Morimoto-san's secret plan to boost his kernel commits statistics ;-)
+10:32 < pinchartl> * Niklas
+10:32 < pinchartl> Since last meeting:
+10:32 < pinchartl> - [PATCH 0/2] rcar-vin: Cleanup how subdevice format is handled
+10:32 < pinchartl> - [PATCH v2 0/2] rcar-vin: Support V4L2_FIELD_SEQ_{TB,BT}
+10:32 < pinchartl> - Attended LPC
+10:32 < pinchartl> Until next meeting:
+10:32 < pinchartl> - Attend ELC-E and join the V4L2 workshop
+10:32 < pinchartl> - Keep pushing VIN patches unlocked by recent acceptance of cleanup patches
+10:32 < pinchartl> Issues and blockers: None
+10:32 < pinchartl> neg: any comment ?
+10:32 < neg> No comment, thanks
+10:33 < morimoto> pinchartl: not *secret* but *official* plan :)
+10:33 < pinchartl> :-)
+10:33 < pinchartl> * Ulrich
+10:33 < pinchartl> Since last meeting:
+10:33 < pinchartl> - Patch review
+10:33 < pinchartl> Until next meeting: N/A
+10:33 < pinchartl> Issues and Blockers: None
+10:33 < pinchartl> uli_: any comment ?
+10:33 < uli_> nope
+10:34 < pinchartl> thank you
+10:34 < pinchartl> any discussion topic ?
+10:35 < neg> Anything to plan/bring to ELC-E ?
+10:35 < wsa> I could bring my Gen2 Alt board for Kieran if he still needs that?
+10:36 < neg> I'm thinking if we need some face-to-face talks or exchange of hardware. I take it we will not have a periperi meeting day ?
+10:36 < pinchartl> wsa: could you check with him ?
+10:36 < pinchartl> kbingham[m]: ^^
+10:36 < geertu> wsa: kbhingham won't be there
+10:36 < pinchartl> geertu: of course. stupid me
+10:36 < wsa> right
+10:36 < pinchartl> Kieran can't get the hardware if doesn't attend
+10:36 < geertu> and the goods may receive increased scrutiny at border control
+10:36 < pinchartl> neg: that was my next question. when will the next meeting be ?
+10:37 < pinchartl> 3 weeks from now is October the 31st
+10:37 < pinchartl> it will collide with the gstreamer conference for Jacopo and me
+10:37 < wsa> that's elce time
+10:37 < pinchartl> and I believe Niklas won't be back home yet either
+10:38 < neg> I will go back home on the 3rd of Nov
+10:38 < pinchartl> should we push it back by one week ?
+10:38 < wsa> yup
+10:38 < pinchartl> so November 7th, same time as usual ?
+10:38 < wsa> works for me
+10:38 < pinchartl> we will have switched to winter time
+10:39 < geertu> pinchartl: Will we? ;)
+10:39 < pinchartl> won't we ?
+10:39 < morimoto> not in Japan :)
+10:39 < geertu> Seems like the killing of DST has been moved to the background noise...
+10:40 < pinchartl> geertu: I think we would have been notified if there would be no chance this autumn
+10:41 < geertu> pinchartl: Right. So ELC-E will be held in Winter Time
+10:42 < geertu> I hope Thalys knows ;-)
+10:42 < pinchartl> so the meeting will start at 17:00 JST, right ?
+10:42 < geertu> I think so
+10:43 < pinchartl> ok
+10:43 < pinchartl> that's all for the multimedia meeting
+10:43 < pinchartl> I propose adjourning, does anyone second ?
+10:43 < neg> second
+10:44 < pinchartl> meeting adjourned. thank you all for attending
