That was just to test whether a particular ExA performance problem would disappear. We have an application called Turtle Art that renders a lot of rounded shapes using Cairo: http://wiki.sugarlabs.org/go/File:TAclock4.png When you drag around a dozen of those bricks on the XO-1 (Geode LX), you get one frame every two seconds. On the XO-1.5 (VIA based), you get fluid 10-20 fps motion. The difference is way too big to be justified by the difference in performance of the CPU or the graphics processor. Any idea? Have you tested rotation (and rotation + Xv) with current GIT code on the older xserver-1.6 found in FC-11 and XO-1 builds? Yes, it worked perfectly now. 90 degrees modes were broken in 2.11.8. What happens after you go back to normal (no) rotation? That is broken for me per http://lists.x.org/archives/xorg-driver-geode/2010-August/000995.html Though we are looking into that already right now, maybe you'd like to come to our IRC again ;) Regards, Mart ___ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel

Hope you can report anything you think incorrect or abnormal after using that new driver. For NoAccel segfault, I am not sure if you have tried Mart's patch in the below link: https://bugs.freedesktop.org/attachment.cgi?id=35326 I have given a try and it can nicely solve this bug. It is caused by the zero pointer use. Could you give a try? I think Mart know more about that. Mart, Can you make this issue more clear for Bernie? I can't reproduce the issue with no display until VT switch anymore, so clearly I was mistaken or it's been solved by a different commit meanwhile, or it just doesn't happen all that often and the idea of crash being better than confusing picture for most people doesn't hold anymore. So I've pushed this trivial segfault fix to GIT now, to be part of 2.11.9. I don't suggest using NoAccel though, as it loses XVideo and many other non-acceleration (read non-deceleration) related things too.

The most outstanding rendering bug has been fixed. And some performance patch has been applied. I tested the driver on the XO-1 and couldn't spot any rendering bug neither in Sugar nor in Gnome, with full acceleration enabled and no quirks needed in xorg.conf. However, a long-standing bug is still there: setting Option NoAccel 1 makes the driver segfault during startup. Thank you very much for taking the time to do this neat work, Frank!

Cairo's slow rendering on XO-1 (was: olpcgames - mainloop bug help)

Any such slowness should be fixed at the root - the xf86-video-geode driver - instead of avoiding GTK/cairo specifically due to that. Unless heavily targeting existing system roll-outs without upgrading of the system, I suppose. While we do already have our work ahead of us in optimizing the standard cairo benchmarks (found in the cairo-traces repository), concrete cases that would benefit the applications used specifically on the XO-1 would be appreciated. Fixing things that can potentially make 1.5 million kids happier can be a great motivator. Ideally this would be presented as a cairo-trace recording as per http://cairographics.org/FAQ/#profiling but I do have a OLPC XO-1 and other Geode LX systems to generate that myself if that's too complex (currently that cairo-trace is only in the development version, and not installed outside build tree), given a description of what program/activity exactly is way too slow and while doing what exactly in that program. Such reports can be sent to freedesktop bugzilla under the Driver/geode component of xorg product, or the xorg-driver-geode mailing list over at http://lists.x.org/mailman/listinfo/xorg-driver-geode Personally to me is also fine, and maybe also good as I can apply some filtering and identify the slow routines beforehand. We also hang out on FreeNode IRC channel #geode More information on http://wiki.x.org/wiki/GeodeDriver Currently we (primarily two AMD employees, not so much me) are concentrating on fixing some of the awful bugs (many of which get triggered only by a newer xorg-server version), such as misrendering with HwAccel and rotation issues. After those are hopefully fixed soon, some attention will probably start to go on hardware acceleration performance, as the current situation is indeed rather sad: http://people.freedesktop.org/~leio/geode/perf/ -- Mart Raudsepp Gentoo Developer, xf86-video-geode contributor Mail: l...@gentoo.org ___ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel
