by Ilias Biris

Status: https://wiki.linaro.org/OfficeofCTO/WeeklyReport Last Meeting minutes: https://wiki.linaro.org/OfficeofCTO/2011-08-30 Not much to report as many were either on vacation or just returning from vac. Highlights: ARMHF: build farm setup for the Freescale quickstart boards used. Build farm is now ready - just waiting to be fit in a machine room at ARM. On the Debian hardfp build: mono/armhf has been uploaded. chromium-browser fails checking why, building both qtwebkit/webkitgtk+ now manually. Konstantinos also reported that he needs to get some 180 packages to be built to reach past the 90% mark Boot architecture: meetings scheduled to restart on the week after LPC.

I will update the milestone page once the decision is taken. Also note the development on MM: Jesse is preparing a GIT tree to contain the patches available, including components from the Video-Multimedia side (eg OMAP DRM driver (maybe others too), xf86-video-omap open source xorg driver). The tree can be made available as a meta-pkg for the Linaro main release in September (add-on "use at own risk" since all this is work still in progress and not upstreamed completely). Details on the tree and how to use it will come during September.

[Request] Can Linaro-dev not send duplicate mail to recipients?

by John Stultz

So being on vacation for a few days and checking my mail and have found an explosion of emails. Unfortunately most of them are duplicates. It seems the linaro-dev list isn't configed to avoid mailing folks who are already recipients of the email. So if you're on linaro-dev and you're also To/CC'ed in the email, you get it twice (three times if your other work email was CC'ed as well, but that cannot be helped). Is this something that can be easily resolved? I really don't know much about maillist servers, but I do know I've not had this issue on other mailing lists. So it should be possible. Thoughts? (but don't CC me! :) -john

11.07 oprofile on panda busted?

by Tom Gall

Hi all, Say has anyone else run oprofile on recent builds on panda? By recent I mean say anything since 11.07? Reason for asking is I'm seeing basically a very very small number of samples being recorded... as in there's no way this is right.

Re: [PATCH] RFCv2: video support for dri2 (Rob Clark)

by Christian König

Hi Rob, > + flipping between multiple back buffers, perhaps not in order (to > handle video formats with B-frames) Oh, yes please. The closed source drivers seems to do this also all the time, and I never really understood why DRI is limiting the buffers to the OGL attachment points. ... > Current solutions use the GPU to do a scaled/colorconvert into a DRI2 > buffer from the client context. The goal of this protocol change is > to push the decision to use overlay or GPU blit to the xorg driver. You left one corner case out, HDMI allows for the framebuffer to be in YUV 4:4:4 format. So it is possible to send YUV data to the display (usually a TV) without color conversion at all, but I think with the current state of X we are years away from that. ... > In many cases, an overlay will avoid several passes through memory > (blit/scale/colorconvert to DRI back-buffer on client side, blit to > front and fake-front, and then whatever compositing is done by the > window manager). On the other hand, overlays can often be handled > directly by the scanout engine in the display hardware, with the GPU > switched off. Actually AMD has thrown out the hardware support for overlay with the R7xx (or was it evergreen?) series, because they got support for turning shader pipes off separately and figured out that it use less power to turn off all shaders except one and then use this one for color conversion and scaling, compared to having a distinct hardware block doing the job. But there are tendencies to get a distinct color conversion block back again. ... > Note: video is not exactly the same as 3d, there are a number of other > things to consider (scaling, colorconvert, multi-planar formats). But > on the other hand the principle is similar (direct rendering from hw > video codecs). And a lot infrastructure of connection, authentication, > is same. So there are two options, either extend DRI2 or add a new > protocol which duplicates some parts.

AFAIK DRI mostly isn't a device driver dependent protocol, and the client side doesn't necessary know to which hardware it is talking, just look at how gallium 3D is working, talking with X over the DRI protocol is part of the driver independent state tracker, and NOT part of the driver itself. So having this driver independent is just a must have, and not optional. > Well, this is the goal anyways.

And I really think it should stay that way. > As far as color conversion matrix... well, the attribute system can > have arbitrary device-dependent attributes.

VDPAU indeed defines two YUVA formats you can use, but currently I haven't seen anybody using the background picture functionality so far, because there are just not so much YUVA videos around.

Preliminary wiki starting page for i.MX53 QuickStart board

by Eric Miao

https://wiki.linaro.org/Boards/MX53QuickStart Sorry guys, although been pushed and pinged several times by various people we are finally able to come up with a preliminary starting page for i.MX53 QuickStart board. It's currently very simple, and hopefully we'll get it more detailed in the future. Feedback is welcome! Thanks - eric
