+10:16 < pinchartl> morimoto: you also reported by e-mail about creating a "pseudo", but I'm not sure to understand what you meant
+10:17 < pinchartl> could you please elaborate ?
+10:17 < morimoto> Ahh
+10:17 < morimoto> The perfect is like this
+10:17 < morimoto> "Linux" + "Intel guys work" + "my work"
+10:18 < morimoto> but "Intel guys work" is based on Intel guys
+10:18 < morimoto> So, I created pseudo code, like this
+10:18 < morimoto> "Linux" + "pseudo Intel code" + "my work"
+10:18 < morimoto> Is it clear for you ?
+10:19 < pinchartl> yes, thank you
+10:19 < pinchartl> do you plan to upstream the pseudo Intel code ? :-)
+10:19 < morimoto> Good question :)
+10:19 < morimoto> but no such plan ;)
+10:20 < morimoto> Sorry for my unclear mail
+10:20 < pinchartl> seriously speaking, if Intel stalls forever, and that blocks your work, after pinging them several times you could take over that work if needed
+10:21 < morimoto> Yeah, I tried it few weeks ago
+10:21 < morimoto> And agreed. thank you for your advice
+10:21 < pinchartl> you're welcome. let me know if I can help

+10:22 < pinchartl> uli___: no MM work planned so far, is that correct ?
+10:23 < uli___> yes
+10:23 < pinchartl> thank you
+10:24 < pinchartl> Topic 2. Discussions
+10:24 < pinchartl> I'll start with
+10:24 < pinchartl> - Face-to-face meeting in Japan
+10:24 < pinchartl> as you probably all know, I met with the BSP team in Tokyo on March the 26th
+10:25 < pinchartl> I explained the multimedia development plan and strategy, and expanded that to also touch areas outside of the MM group
+10:26 < pinchartl> the feedback I have received during the meeting was limited, and mostly consisted of BSP requests for MM development unrelated to the plan that was presented
+10:26 < pinchartl> *however*
+10:26 < pinchartl> there were several interesting points worth noting
+10:27 < pinchartl> one, even though I tried to include more text than usual on my slides to make it easier to follow, there was still probably a language barrier that made communication a bit hard
+10:27 < pinchartl> I know I speak too fast :-S
+10:27 < pinchartl> so the BSP team has received the slides, and Morimoto-san said they would provide feedback on the plan
+10:27 < pinchartl> two, the budget situation is very unclear, with all options being on the table
+10:28 < pinchartl> in some discussions the future looked gloomy, but in others the BSP team talked about Gen4
+10:28 < pinchartl> we don't know what will happen next year (or even after Q3) but hoping is still permitted
+10:29 < pinchartl> three, on the multimedia side, there was a good match between key areas we have identified and one request from the BSP team related to VSP performance improvement
+10:29 < pinchartl> that match is the request API, which I plan to propose as one of the core work items for MM in the next two quarters
+10:30 < pinchartl> to finalize the plan proposal I will need the feedback from the BSP team I mentioned above
+10:30 < pinchartl> four, I explained during the meeting that the thin slicing of budget in small additional tasks made it difficult to tackle bigger development tasks
+10:30 < pinchartl> and asked if we could solve that somehow
+10:30 < pinchartl> the request seemed to be well received, and Morimoto-san said he would try to help with that
+10:31 < pinchartl> we thus need to make a proposal
+10:31 < pinchartl> this depends on the finalization of the development plan
+10:31 < pinchartl> that's a coarse summary of the discussions
+10:31 < pinchartl> any question or comment ?
+10:31 < pinchartl> morimoto: anything you would like to add, anything I missed ?
+10:32 < morimoto> please wait few min
+10:32 < neg> morimoto: pinchartl: Thanks to you both for having this meeting and sharing the results of it
+10:33 < pinchartl> morimoto: sure
+10:33 < pinchartl> neg: you're welcome
+10:33 < pinchartl> in the meantime, any other question or comment ?
+10:33 < pinchartl> or any other discussion point for today (I want to discuss additional tasks for Q2)
+10:33 < neg> pinchartl: I know the burden of traveling to Japan for it must have been gruesome ;-)
+10:34 < wsa> I want to point out (again) that M/M is (rightfully) different from IO, and probably core
+10:34 < morimoto> About one, sorry for our English skill
+10:34 < pinchartl> neg: you know I will always donate my person for the good cause (I hope this comes out correctly in English)
+10:34 < wsa> the thin slicing wasn't too bad for IO
+10:34 < pinchartl> morimoto: no need to be sorry. the issue wasn't caused by your bad English skills, it was caused by my lack of Japanese skills :-)
+10:34 < wsa> but I understand that it was difficult for M/M
+10:35 < pinchartl> wsa: I agree, the problem differs in the three groups, and also depends on the tasks at hand
+10:35 < wsa> I'm just saying a "one process for all" will always face this diversity
+10:36 < morimoto> About three, thank you for your help
+10:36 < neg> For the limitations we identified in MM I think it's encouraging that talk of how to handle that in a new format of additional contracts have started
+10:36 < morimoto> About four, it depends with two
+10:37 < morimoto> But I want to solve the issue
+10:37 < morimoto> It needs Jinso-Renesas-Magnus-SoW connection
+10:38 < morimoto> It is my (our) home-work
+10:39 < pinchartl> my opinion is that the SoWs and additional tasks are related to the development plan. I would thus like to finalize the plan based on the feedback from the BSP team, and then discuss together how we can create SoWs that keep the concept of additional tasks, but make that fit with larger development
+10:39 < pinchartl> do you know when we could receive feedback on the proposals ?
+10:40 < morimoto> from BSP team ?
+10:40 < pinchartl> yes
+10:40 < morimoto> I'm waiting it. I will send ping to them
+10:41 < pinchartl> thank you
+10:42 < pinchartl> any other question or comment ?
+10:43 < neg> Is it too early to start to plan Renesas days around OSSJ ?
+10:43 < pinchartl> I'd say the earlier the better
+10:44 < pinchartl> the first question is then, will we have a periperi meeting in Japan ?
+10:44 < pinchartl> (around OSSJ-
+10:44 < pinchartl> )
+10:45 < pinchartl> morimoto: any plan on Renesas side ?
+10:45 < morimoto> No plan so far
+10:46 < pinchartl> morimoto: do you think we should make a plan ? :-)
+10:46 < wsa> I am not going to OSSJ this year, too many schedule conflicts :(
+10:46 < pinchartl> wsa: :-(
+10:46 < morimoto> I'm plannng so far for OSSJ is Chanko which is requested from wsa
+10:46 < pinchartl> how about everybody else, who plans to go, who will not go, and who is still undecided ?
+10:46 < morimoto> wsa: Grrr you don't this year
+10:47 < pinchartl> I know Kieran will likely not be able to join, due to having a wedding on both sides of the conference
+10:47 < wsa> morimoto: didn't i tell you?
+10:47 < uli___> i intend to go
+10:47 < pinchartl> (getting married once is already crazy, having two weddings is even worse if you ask me :-))
+10:47 < pinchartl> uli___: that's the right decision :-)
+10:47 < kbingham> Correct. OSSJ is highly unlikekly for me I'm afraid.
+10:47 < morimoto> wsa: did you ? I don't remember...
+10:47 < wsa> i thought we discussed OSSJ attendance somewhen already on IRC
+10:48 < pinchartl> geertu: how about you ?
+10:48 < neg> kbingham: will the divorce papers clear in time for the second wedding?
+10:48 < pinchartl> horms: same question ?
+10:48 < wsa> morimoto: I'm sad myself :'-(
+10:49 < kbingham> neg, They'll be fine.
+10:49 < horms> If the question is about OSSJ then the answer is that I currently have no plans to attend
+10:49 < morimoto> wsa: I will miss you, so much...
+10:49 < pinchartl> horms: yes, that was the question. would you make plans to attend if needed, or is that unlikely ?
+10:50 < wsa> maybe we should do this by email, but what about you guys attending Plumbers (Lisboa) and/or Embedded/Kernel-Recipes (Paris) in September
+10:50 < wsa> ?
+10:50 < wsa> morimoto: will we meet in Lyon at ELCE?
+10:50 < pinchartl> wsa: LPC or ELCE would be a good idea too
+10:50 < morimoto> Maybe I can't joint to ELCE this year
+10:51 < morimoto> s/joint/join/
+10:51 < pinchartl> morimoto: I suppose it depends on the budget situation, and we will only know about it later ?
+10:52 < pinchartl> geertu: ping ?
+10:52 < horms> pinchartl: if its important I can make a plan. but other plans would work better for me, f.e. I do plan to attend LPC and ELCE would take me about as long to drive to as it would to fly to OSSJ
+10:53 < pinchartl> horms: ok
+10:53 < pinchartl> so a whole periperi meeting seems more likely at LPC or ELCE time than OSSJ time at the moment
+10:53 < pinchartl> I have submitted a talk proposal for OSSJ so I will likely go
+10:54 < pinchartl> maybe we'll have a MM meeting instead of a global meeting then
+10:54 < geertu> pinchartl: I can go to OSSJ
+10:55 < pinchartl> geertu: nice :-)
+10:55 < geertu> I will be at Embedded-Recipes (invited speaker)
+10:55 < wsa> same here for Embedded Recipes
+10:55 < geertu> It's been 3 years since I've been to JP :-(
+10:55 < wsa> not sure about Plumbers yet
+10:55 < geertu> wsa: Marex did a good job ;-)
+10:55 < pinchartl> what will you speak about at RC ?
+10:55 < wsa> yes :D
+10:55 < pinchartl> s/RC/ER/
+10:56 < geertu> pinchartl: No topic set so far
+10:56 < wsa> similar here, a rough idea was to speak about my subsystem (new things, workflow...)
+10:56  * geertu considers a talk about the Japanese cherry tree in his garden
+10:58 < pinchartl> :-)
+10:58 < geertu> Probably I should install a camra to take daily Sakura pictures
+10:58 < wsa> morimoto: you are not coming to Lyon? Well, looks like I need to find another excuse than OSSJ to come to Japan then :)
+10:58 < geertu> And I plan to attend ELCE, as usual
+10:59 < geertu> (until LF has exploded by then)
+10:59 < geertu> s/until/unless/
+11:00 < pinchartl> any plan to make LF explode ?
+11:00 < wsa> Yeah, I plan for ELCE, too
+11:01 < morimoto> wsa: yeah, I can't this year. so sorry
+11:01 < geertu> http://techrights.org/2019/03/30/what-happened-lf/
+11:02 < pinchartl> geertu: interesting, I had missed that
+11:02 < pinchartl> anyway, the conclusion for now is
+11:02 < pinchartl> likely no official global meeting around OSSJ
+11:02 < pinchartl> perhaps a multimedia meeting
+11:03 < pinchartl> and perhaps a global meeting around LPC or ELCE (but that is likely conditioned by budget)
+11:03 < pinchartl> next discussion topic for the MM meeting
+11:03 < pinchartl> additional tasks for Q2
+11:03 < pinchartl> as discussed before, the plan is to makes those tasks fit in the global MM development plan
+11:04 < pinchartl> I would like to already move forward with tasks related to the request API
+11:04 < pinchartl> for other tasks, I would like to first receive feedback from the BSP team on the plan
+11:04 < pinchartl> neg: if I understand correctly, you have all your additional task time allocated already for Q2, right ?
+11:06 < marex-cloud> morimoto: I'll likely be at OSSJ :)
+11:06 < geertu> marex-cloud: Critical mass reached!
+11:07 < marex-cloud> geertu: heh
+11:07 < neg> pinchartl: yes Q2 already allocated
+11:07 < marex-cloud> geertu: I'll also be at ER most likely, I seem to be roped into a special role
+11:07 < pinchartl> neg: thanks
+11:08 < marex-cloud> geertu: godfather was the name I think
+11:08 < pinchartl> so I'll work on a proposal for the request API already, and wait for feedback for the rest
+11:08 < pinchartl> any other dicussion topic for today ?
+11:09 < neg> not from me, thanks
+11:09 < morimoto> marex-cloud: nice to know :)
+11:09 < marex-cloud> geertu: what about doing a trip to Toyama around OSSJ, eat great food etc?
+11:09 < pinchartl> I then propose adjourning this meeting. does anyone second ?
+11:10 < neg> second
+11:10 < morimoto> 3rd
+11:10 < marex-cloud> morimoto: maybe I should consider relocation ^_^'
+11:10 < morimoto> marex-cloud: sorry for what ?
+11:10 < pinchartl> meeting adjourned. thank you all for attending
