+09:42 < pinchartl> so welcome to the multimedia meeting
+09:42 < pinchartl> I think we have a full house today
+09:42 < pinchartl> jmondi, kbingham[m], dammsan, morimoto, neg, uli___, yes
+09:42 < pinchartl> first topic, status updates
+09:43 < pinchartl> from last to first, let's start with Morimoto-san
+09:43 < pinchartl> I'll post the update and ask for comments, like last time
+09:44 < pinchartl> Since last meeting:
+09:44 < pinchartl> - Posted ALSA SoC framework main cleanup patches
+09:44 < pinchartl> Patches are too big, asked each driver author to test them. Few issues are already noticed and fixup patches posted.
+09:44 < pinchartl> - Export paper work for datasheet, schematic, board, etc
+09:45 < pinchartl> Until next meeting:
+09:45 < pinchartl> - Continue the ALSA SoC framework things
+09:45 < pinchartl> Issues and Blockers: None (other than paperwork killing your soul)
+09:45 < pinchartl> any comment ?
+09:47 < morimoto> no comment
+09:47 < pinchartl> while waiting for comments, let's continue with Niklas
+09:47 < pinchartl> ok :-)
+09:47 < pinchartl> thank you
+09:47 < pinchartl> neg:
+09:47 < pinchartl> Since last meeting:
+09:47 < pinchartl> - [PATCH 0/5] GMSL: enable multiple simultaneous streams from the same MAX9286
+09:47 < pinchartl> - [PATCH] v4l2-dev.h: fix symbol collision in media_entity_to_video_device()
+09:47 < pinchartl> - Prepared VIN, CSI-2 and multiplexed patches for the GMSL code camp
+09:47 < pinchartl> Until next meeting:
+09:47 < pinchartl> - Media code camp working on GMSL related stuff..
+09:47 < pinchartl> - Post next versions of VIN, CSI-2 and multiplexed pads series
+09:47 < pinchartl> - Look if rcar-vin can more aggressively switch to continues capture  mode if it due to buffer starvation enters single capture mode.
+09:47 < pinchartl> - Start on DU integration for V3M.
+09:47 < pinchartl> Issues and Blockers:
+09:47 < pinchartl> - Laurents excellent review comments on VIN have resulted in a rewrite of some parts of the driver. End result is much cleaner but have taken more time than expected.
+09:47 < pinchartl> any comment ?
+09:48 < neg> Thanks for your comments, other than that no :-)
+09:48 < pinchartl> next, Jacopo
+09:48 < pinchartl> Since last meeting:
+09:48 < pinchartl> - v4/5/6 of the CEU driver
+09:48 < pinchartl> Rebased on Hans' parm branch, fixed v4l2-compliance issues.
+09:48 < pinchartl> - Add DTS support to ov7670 driver
+09:48 < pinchartl> This was needed to test CEU polarities, now waiting for DT bindings ack.
+09:48 < pinchartl> - Build and test the Cogent GMSL Yocto layer
+09:48 < pinchartl> - Got FSYNC working
+09:48 < pinchartl> Compared Cogent's settings again then niklas->magic() and got fsync working 
+09:48 < pinchartl> keeping reverse communication channel open as GPO transitions are sent through 
+09:48 < pinchartl> it.
+09:48 < pinchartl> Until next meeting:
+09:48 < pinchartl> - GMSL Code Camp: consolidate setup and test fsync reliability
+09:48 < pinchartl> - Brussels FOSDEM
+09:48 < pinchartl> - Handle frame rate setting in the ov7720 driver
+09:48 < pinchartl> This implies working on Migo-R clocks and reverse engineer a poorly documented 
+09:48 < pinchartl> sensor. Hans won't take the driver otherwise, or we can park it in staging.
+09:48 < pinchartl> Issues and Blockers: None
+09:48 < pinchartl> any comment ?
+09:49 < jmondi> nope
+09:49 < jmondi> that's all
+09:49 < pinchartl> thanks
+09:49 < pinchartl> next, Ulrich
+09:49 < pinchartl> Since last meeting:
+09:49 < pinchartl> - Attempted to get mainline-patched GSX driver to work with Yocto
+09:49 < pinchartl> Until next meeting:
+09:49 < pinchartl> - Multimedia meeting in Belgium
+09:49 < pinchartl> - Brussels FOSDEM
+09:49 < pinchartl> - Multimedia-related PFC upstreaming for Gen3 SoCs
+09:49 < pinchartl> Issues and Blockers:
+09:49 < pinchartl> - The GSX driver still doesn't work (except for OpenCL)
+09:49 < pinchartl> Even the officially sanctioned Yocto userspace fails, so it seems increasingly
+09:49 < pinchartl> unlikely that it is userspace-related. Help from someone (i.e. Laurent) to 
+09:49 < pinchartl> check if the up-port of the DRM bits in Rogue driver makes sense when we meet 
+09:49 < pinchartl> in Brussels would be useful.
+09:49 < pinchartl> any comment ?
+09:50 < uli___> please help me. :)
+09:50 < pinchartl> :-)
+09:50 < morimoto> :)
+09:50 < pinchartl> I think we can have a look at it in Brussels
+09:50 < uli___> ok, thanks
+09:50 < pinchartl> can you make sure to prepare everything to avoid spending time with build or other similar issues ?
+09:51 < uli___> i'll prepare everything
+09:51 < pinchartl> you will arrive on Thursday, right ?
+09:51 < uli___> yes, early afternoon
+09:51 < pinchartl> let's try to address that on Thursday later afternoon then
+09:52 < uli___> ok
+09:52 < uli___> there's going to be an h3 board there, right?
+09:52 < pinchartl> I'll have a kingfisher with an H3SK
+09:52 < pinchartl> and Kieran will bring a Salvator-XS
+09:53 < pinchartl> next, Kieran
+09:53 < pinchartl> * Kieran
+09:53 < pinchartl> Since last meeting:
+09:53 < pinchartl> - GMSL investigations and Yocto builds with Jacopo
+09:53 < pinchartl> Extracted the Cogent Kernel so we can build independently.
+09:53 < pinchartl> - ADV748x TXB lane power investigation and support
+09:53 < pinchartl> - vsp1/tlb-optimise/v5 (rebase for updated DRM/UIF)
+09:53 < pinchartl> - Eagle-V3M Display testing
+09:53 < pinchartl> - ADV748x invalid page mapping fix
+09:53 < pinchartl> - ADV7511 device tree I2C address mapping
+09:53 < pinchartl> - ADV7604 device tree I2C address mapping
+09:53 < pinchartl> Until next meeting:
+09:53 < pinchartl> - GMSL Code Camp
+09:53 < pinchartl> - Brussels FOSDEM
+09:53 < pinchartl> - H3 ES2.0 LVDS + VGA Performance Investigation
+09:53 < pinchartl> Issues and Blockers:
+09:53 < pinchartl> - Draak D3 I2C support not yet integrated into renesas-drivers
+09:53 < pinchartl> Draak ADV7511/ADV7612 development is based on out-of-tree patches.
+09:53 < pinchartl> any comment ?
+09:54 < kbingham> That's it - except for taking advantage of Uli being here so I can ask if he plans to work on the D3 i2c patches anytime (it doesn't matter if you don't plan too - I think geertu might pick the patches up for next renesas-drivers anyway, or I can base on the ones I have)
+09:55 < kbingham> or rather uli___:  ^ :D
+09:55 < uli___> no immediate plan, but that's mostly because i forgot about those
+09:55 < pinchartl> that was my question too, what are the plans to get that upstream ?
+09:55 < uli___> i'll have a look
+09:56 < kbingham> Ok, that's me done for today then :D
+09:56 < pinchartl> thank you
+09:57 < pinchartl> oh, last time you mentioned you were planning to resubmit kmstest verification based on review comments
+09:57 < pinchartl> any update on that ?
+09:59 < kbingham> Nope - it got stalled, blocked by other tasks - so I'll try to get that done this cycle.
+10:01 < pinchartl> there's no hurry, but please keep it on your todo list
+10:01 < pinchartl> I got the order wrong and nearly forgot Jacopo again
+10:01 < pinchartl> Since last meeting:
+10:01 < pinchartl> - v4/5/6 of the CEU driver
+10:01 < pinchartl> Rebased on Hans' parm branch, fixed v4l2-compliance issues.

+10:01 < pinchartl> Issues and Blockers: None
+10:01 < pinchartl> any comment ?
+10:02 < jmondi> you have pasted my report already :)
+10:02 < jmondi> this time I don't feel left out :)
+10:03 < jmondi> and no comments neither this time!
+10:03  * pinchartl needs to wake up -_-'
+10:03 < pinchartl> a few questions though
+10:04 < pinchartl> do you still need support from Omnivision and Maxim ?
+10:04 < jmondi> for GMSL?
+10:04 < jmondi> I guess we'll find out once we can test fsync stability a bit more in Brussels
+10:05 < morimoto> jmondi: I forwarded their response for you. does it works ?
+10:05 < pinchartl> of course, but is there any open question for which we're still waiting for an answer ?
+10:05 < morimoto> About register setting list
+10:05 < jmondi> everything was revolving around fsync, now that niklas has made it working everything else is secondary
+10:06 < pinchartl> ok, thanks
+10:06 < jmondi> I guess we'll may need support when implementing support for more image resolutions
+10:06 < jmondi> morimoto: yes thanks, that would be required when changing the image sizes
+10:06 < pinchartl> finally, myself
+10:06 < pinchartl> Since last meeting:
+10:06 < pinchartl> - Prepared the FOSDEM code camp
+10:06 < pinchartl> - DU LVDS rework
+10:06 < pinchartl> - Patch review
+10:06 < pinchartl> - Started virtualization investigation
+10:06 < pinchartl> Until next meeting:
+10:06 < pinchartl> - GMSL Code Camp
+10:06 < pinchartl> - Brussels FOSDEM
+10:06 < pinchartl> - Virtualization investigation
+10:06 < pinchartl> Issues and blockers: None
+10:08 < morimoto> jmondi: nice to know
+10:08 < pinchartl> so that's it for the status update
+10:08 < pinchartl> any question or comment ?
+10:09 < morimoto> yes
+10:09 < morimoto> pinchartl: I still can't find my DU 2 PLL fixup patches on linux-next.
+10:10 < pinchartl> morimoto: that's because I still haven't sent the pull request. as the merge window is about to open the DRM tree is currently frozen
+10:10 < pinchartl> I will send it as soon as the merge window closes
+10:10 < morimoto> OK, your branch is not connected to linux-next directly (I don't know detail of it)
+10:11 < pinchartl> no, it gets in linux-next through the DRM tree
+10:11 < morimoto> Thanks ! nice to know
+10:12 < pinchartl> dammsan: anything to report by any chance ? :-)
+10:12 < dammsan> nope, sorry =)
+10:12 < dammsan> just that i'm currently discussing your task proposals
+10:13 < pinchartl> that at least is nice to hear
+10:13 < dammsan> hope to get back to your about that tomorrow
+10:13 < pinchartl> which leads to
+10:13 < pinchartl> Topic 2. Additional Tasks for 2018 Q1
+10:13 < pinchartl> Additional tasks for 2018 Q1/1 have been approved, and candidates for 2018 
+10:13 < pinchartl> Q1/2 submitted. The goal is to agree on the second batch for the end of 
+10:13 < pinchartl> January.
+10:13 < pinchartl> I assume you've all seen the proposals for Q1/2
+10:15 < kbingham> yes, (now refreshed for a second time)
+10:16 < pinchartl> neg: what would you think about the single/continuous capture mode support in VIN for Q1/2 ? it seems the BSP team would like to have it sooner than later
+10:16 < neg> pinchartl: was just about suggest that so it would work good for me :-)
+10:18 < pinchartl> dammsan: would that be OK with you ?
+10:20 < dammsan> sure of course
+10:20 < pinchartl> can you add it to the list of tasks to discuss with Renesas then ?
+10:20 < dammsan> most important is to keep upstream focus though, so as long as we don'tloose that
+10:20 < dammsan> i can
+10:20 < dammsan> and will
+10:21 < pinchartl> thank you
+10:21 < pinchartl> jmondi, kbingham, uli___: any comment on the proposed tasks ?
+10:21 < neg> dammsan: that task do not depend on VIN Gen3 support being merged first :-)
+10:22 < uli___> i would like to look into the size and quality of that igt test suite before deciding whether that is 5 days
+10:22 < uli___> other than that, i'm happy
+10:22 < dammsan> neg: ok, not sure if it is good or bad =)
+10:23 < pinchartl> uli___: ok. you won't need to get all tests running, an initial subset would be enough
+10:23 < uli___> ok
+10:23 < jmondi> For me D3 VIN supports seems fine, I'm not sure everythihg we need is upstream (ie D3 i2c). I have to made sure any of the camera modules I have may be connected to D3 expansions
+10:23 < jmondi> and, what's DISCOM? :)
+10:24 < pinchartl> it's a VSP module that computes CRCs
+10:25 < jmondi> target platforms? I have an M3-W and a D# here
+10:25 < jmondi> nice D#.. D3 I meant
+10:27 < pinchartl> M3-W will work
+10:27 < neg> jmondi: V3M also have a parallel input on its expansion board and there i2c works and I have verified the HDMI/CSI-2 input on the expansion board if all else fails
+10:28 < jmondi> neg: nice, but I don't have V3M... ofc there's the remote option, but I need to wire a camera to the expansion headers
+10:30 < pinchartl> next topic, GMSL code camp
+10:30 < pinchartl> by now I assume you all have sorted out your travel plans
+10:30 < pinchartl> and know what to bring
+10:30 < pinchartl> please make sure you enter your travel plans in the wiki
+10:32 < jmondi> FYI: https://osdr.renesas.com/projects/linux-kernel-development/wiki/Periperi-2018-02
+10:32 < pinchartl> I will post an agenda proposal for the Thursday afternoon multimedia meeting
+10:32 < pinchartl> regarding the code camp itself I think the agenda is quite simple
+10:32 < pinchartl> any question ?
+10:33 < kbingham[m]> Neg, can you provide our latest gmsl branch to test?
+10:34 < kbingham[m]> That is assuming that your latest patches are the most recent work
+10:34 < neg> kbingham[m]: I'm working on bulding it, got gready and wanted the latest VIN patches as it's base. As soon as it's done I will provided a tag
+10:35 < kbingham[m]> Great
+10:35 < pinchartl> thank you
+10:36 < pinchartl> regarding logistics, I will likely arrive in Brussels first
+10:38 < neg> I will arrive Sunday BRU 1900 if anyone want to share a cab
+10:38 < pinchartl> any other question ?
+10:39 < jmondi> and I'll land at 19.35 if I'm not wrong
+10:39 < jmondi> no question though
+10:39 < kbingham> Best ways of contacting people upon arrival ?
+10:39 < kbingham> jmondi - whatsapp, pinchartl sms, neg ?
+10:39 < pinchartl> sms or phone for me, yes
+10:39 < kbingham> (kb, IRC, whatsapp, or sms)
+10:40 < neg> kbingham[m]: phone or sms is best for me
+10:41 < jmondi> IRC, telegram or if no alternatives whatsapp
+10:42 < pinchartl> any other topic to discuss ?
+10:42 < neg> not from me
+10:43 < pinchartl> I then propose adjourning this meeting. any objection ?
+10:43  * kbingham seconds
+10:43 < geertu> jmondi: Please don't use telegrams to contact me. The service was stopped in Belgium on 2017-12-29.
+10:43 < pinchartl> meeting adjourned
+10:43 < pinchartl> thank you all for attending
