10:55 < pinchartl> Status unclear, but seems part of du/next. Will be investigated further.

10:55 < pinchartl> jmondi: anything to discuss then ?
10:56 < pinchartl> or did you just want to report that ?
10:56 < jmondi> this should be integrated in Niklas' great work on importing upport tasks in periject
10:57 < jmondi> apart from that we have clarified off-line most of these tasks
10:57 < pinchartl> how about we import them, and you send a periject patch on top to address these ?
10:57 < jmondi> I will investigate "drm: rcar-du: Fix dpad signal routing for R8A7799X"
10:57 < jmondi> and adv7511 suspend/resume
10:58 < jmondi> pinchartl: you mean first get Niklas' patch in, and then send patches on top? fine with me
10:58 < pinchartl> yes
10:58 < pinchartl> thank you
10:58 < pinchartl> Topic 3. Discussions
10:58 < pinchartl> any topic to discuss ?
10:59 < jmondi> pinchartl: should I wait for more reviews on v4l2-mux before trying to handle the CSI-2 data lane negotiation?
10:59 < jmondi> or could I send on top of v3?
10:59 < pinchartl> I think you can send it on top
10:59 < jmondi> pinchartl: do you plan to review v3? :p
11:01 < pinchartl> yes I do :-)
11:01 < jmondi> thanks :)
11:01 < neg> Any update on the Multimedia development plan work?
11:01 < jmondi> ah! Sakari just replied to v3 :)
11:02 < pinchartl> neg: I think at this stage I'd like to have initial feedback from Japan
11:02 < pinchartl> on Jacopo's proposal
11:02 < pinchartl> in order to discuss and finalize the plan with the team
11:02 < pinchartl> before going to Japan
11:03 < pinchartl> morimoto: damm: do you plan to review the plan proposal sent by Jacopo ?
11:04 < morimoto> I think we need to. damm-san ?
11:04 < neg> I was wondering if you had any feedback on that from none mail sources but a face to face meeting coming up might be better. I'm just being curious :-)
11:05 < pinchartl> damm: have we lost you ? :-)
11:06 < morimoto> damm: I miss you... so.. much...
11:07 < jmondi> morimoto: :)
11:07 < pinchartl> while waiting for Magnus to reply
11:07 < damm> yes
11:07 < pinchartl> ah
11:07 < pinchartl> good timing :-)
11:07 < pinchartl> was that a "yes, we lost you" ?
11:08 < damm> pretty much, but morimoto-san and i need time to review
11:08 < jmondi> morimoto: and no, we very much like you, but we all hate HTML :p
11:08 < pinchartl> have you had a chance to read Jacopo's e-mail ? do you have any feedback, or could you provide feedback by the end of next week ?
11:08 < pinchartl> damm: sure, take your time
11:09 < morimoto> jmondi: hehe :)
11:09 < pinchartl> let me know if you would like to schedule a HO discussion about it, or if you prefer interacting over e-mai
11:09 < pinchartl> l
11:09 < pinchartl> do you think you could provide early feedback by the end of next week ?
11:11 < damm> let me and morimoto-san check our schedules and see if we can meet
11:11 < pinchartl> thank you
11:11 < pinchartl> Topic 4. Additional Tasks for 2019 Q2
11:11 < pinchartl> it's time to start thinking about those
11:11 < pinchartl> but there's a question that needs to be answered first
11:12 < pinchartl> what's the budget situation for Q2 ?
11:12 < pinchartl> I'm afraid this is again a question for our esteemed Japanese team members
11:13 < morimoto> It is very serious question
11:13 < morimoto> Only I can say *so far* is that Q2 is no problem *at this point*
11:14 < pinchartl> ok
11:14 < pinchartl> does this mean that we should currently consider that the Q2 budget will be identical to the Q1 budget, and start submitting additional tasks accordingly ?
11:15 < morimoto> I think so, shimoda-san any comment ?
11:18 < morimoto> shimoda: I miss you... so.. much... again...
11:18 < morimoto> what's happen at Japanese network ??
11:20 < shimoda> sorry for delayed. as morimoto-san mentioned, Q2 budget is OK (same as Q1)
11:21 < pinchartl> ok
11:22 < pinchartl> we will then start proposing additional tasks
11:22 < pinchartl> any other topic to discuss today ? if not, I propose adjourning this meeting
11:23 < neg> No other topics from me
11:23 < jmondi> neg: let's sync on updating periject maybe
11:24 < jmondi> no other topics from me, thank you all
11:24 < geertu> Woops, will we switch to Summer Time on March 31, or not?
11:24 < neg> jmondi: I was hoping pinchartl would push my patch once he have looked at it
11:24 < neg> jmondi: And all changes would go on top of that
11:24 < jmondi> geertu: for the last time, yes!
11:24 < pinchartl> neg: I'll review your patch indeed, and we can then push it
11:25 < pinchartl> I think we can do so offline
11:26 < neg> sounds good to me
11:26 < pinchartl> geertu: does it mean that the next meeting will be at 16:00 JST ?
11:26 < geertu> 08:00 BST / 09:00 CEST / 10:00 EEST /  12:30 IST / 16:00 JST.
11:26 < geertu> (assuming I don't have it wrong)
11:27 < pinchartl> that's my understanding too, thanks
11:27 < pinchartl> multimedia meeting adjourned
11:27 < pinchartl> thank you all for attending, and have a nice day
