Meeting started at 14:04. The chair is alf_.

[TOPIC] review actions from last meeting

  • <alf_> fgu file bug against linaro-image-tools on proxy problems

  • <alf_> fgu: how did that go?

  • <alf_> hmm, perhaps fgu is not actually here, so let's move on:

  • <alf_> asac and kunal to work on way to autobuild all linaro kernel flavours daily

  • <alf_> neither asac nor kunal are here (public holiday in india)... so let's move on again

  • <alf_> tgall tgall to move his specs

  • <tgall_foo> that's done

  • <alf_> great :)

[TOPIC] review team work

  • <alf_> it has been mostly spec work this week

  • <alf_> tgall_foo: do we have a summary for last week?

  • <tgall_foo> for last week yes ... if you're asking about the summer for this past week's work... no that's not drafted as of yet as far as I know

  • <alf_> ok

  • <alf_> so most specs should be in final review stage right now

  • <alf_> does anyone have any issues or unresolved questions regarding their spec that is blocking them from finishing?

  • <JesseBarker> i've seen a flurry of updates to blueprints, so i assume that means folks have been getting feedback and making progress.

  • <tgall_foo> it looks like we have a number of specs that aren't yet into a Review state

  • <JesseBarker> tgall_foo: do you have a list?

  • <alf_> hmm, it is unfortunate that we have people missing today (due to holiday)

  • <tgall_foo> JesseBarker, I'm looking at : https://blueprints.launchpad.net/linaro-multimedia-wg and https://blueprints.launchpad.net/linaro-graphics-wg

  • [ACTION] Tech leads to check the teams specs and push completion

  • <alf_> so let's talk more about this in the wg progress reports

  • <tgall_foo> sounds good

[TOPIC] progress reports [PROGRESS REPORT] Graphics WG (Jesse)

  • <JesseBarker> well, i've sent out my slide deck for the plan announcement to the up mail alias

  • <JesseBarker> i've also asked a couple of other folks for some advance review.

  • <JesseBarker> as i need to submit those slides to the tsc and other tech leads in the next 24 hours, quick review would be helpful.

  • <JesseBarker> on other fronts, i've begun a dialog with martin of kwin, but no response.

  • <jazh> JesseBarker: when/where can we get your slides? ;)

  • <tgall_foo> more generally if you haven't been listening in to the plan reviews it's a good idea just to see what other teams are doing : https://wiki.linaro.org/Releases/1105/PublicPlanReview

  • <JesseBarker> jazh: should be in your mailbox in pdf form

  • <JesseBarker> tgall_foo: thanks for the pointer.

  • <jazh> JesseBarker: that's great, thanks

  • [ACTION] All (especially gfx wg members) to check Jesse's slides

  • >JesseBarker< wasn't directed at you but more for everyone in the room .. I know you've been attending :-)

  • <JesseBarker> i've also been discussing our upstream plans with the DRM maintainer, though, i must admit, his stance is a little disconcerting.

  • <tgall_foo> could you elaborate a bit on that ?

  • <JesseBarker> aside from that, i think it's been specs and blueprints all the way around.

  • <JesseBarker> tgall_foo: you mean on the DRM maintainer's stance?

  • <tgall_foo> JesseBarker, yes

  • <JesseBarker> well, it seems as though he's holding firm on the idea that vendors must either release all of their user space code that talks to the kernel space code they release.

  • <JesseBarker> and in addition, they must provide security specs and full API coverage between the kernel and user space pieces.

  • <JesseBarker> or, provide enough hardware specs that someone else can write a driver.

  • <tgall_foo> mmm I see where that would be troubling

  • <JesseBarker> no one really does that at present, so i'm not sure how this model actually works in the real world.

  • <JesseBarker> intel and amd provide enough specs for you to get pixels on the screen, but not enough to write a driver you could use in production.

  • <JesseBarker> no one releases their complete sources.

  • <tgall_foo> yeah that position on his part in my opinion needs a bit of a reality check

  • <JesseBarker> so, again, i'm trying to figure out whom this model works for (apart from him personally).

  • <JesseBarker> alf_: i think that's it for graphics wg.

  • <alf_> JesseBarker: Any issues with specs?

  • <JesseBarker> none that i'm aware of. unless i hear differently, folks are making progress, and updating specs and blueprints according to the planning.

  • <JesseBarker> and i've just updated the remaining blueprints that are planned for this cycle as "review".

  • <alf_> Well, I am finished...

  • <alf_> jazh: anything remaining?

  • <jazh> alf_: I also just removed my blueprints to review

  • <alf_> JesseBarker: ok, thanks for the update!

  • <alf_> great then, moving on!

[PROGRESS REPORT] Multimedia WG (asac)

  • <alf_> asac is not here, and neither is the vast majority of the team so moving on again

  • <alf_> unless someone wants to add something

[PROGRESS REPORT] Distribution (tgall_foo, kunal)

  • <tgall_foo> not much to report given where we are in the natty cycle... still waiting on slangasek on the linaro-development seed that I pushed forward for review

  • <tgall_foo> that multimedia and graphics wg seeds will be based on that unless slangasek and JamieBennett change course on the matter

  • <tgall_foo> that's all I have .. any questions ?

  • <alf_> do you have a link for the seed?

  • <JesseBarker> tgall_foo: i'm presenting that model of the graphics seed at the planning talk, so they will have a chance to comment then as well.

  • <tgall_foo> alf_, https://code.launchpad.net/~tom-gall/linaro-seeds/linaro.natty-add-linaro-development/+merge/40587

  • <tgall_foo> JesseBarker, sounds good, thanks!

  • <alf_> tgall_foo: thanks

  • <tgall_foo> JesseBarker, I don't anticipate it to be really controversial ... linaro-development adds about 100Meg (compressed) to the image size which for images with graphical interfaces isn't too bad

  • <alf_> good... finally:


  • <JesseBarker> fyi, it's been posted on linaro leaves for a while, but i'm on holiday with family all next week.

  • <alf_> JesseBarker: good, have fun ;)

  • <tgall_foo> yeah Thurs/Fri is a holiday here in the US

  • <tgall_foo> (well Friday isn't officially but many take it off)

  • <jazh> JesseBarker, tgall_foo: enjoy your holidays ;)

  • <tgall_foo> anyway ... I have Ogre3d built on arm using their most recent code ... compiled for quite a long time so shall start testing it this morning

  • <alf_> I guess that's it then...

Meeting finished at 14:37.
