[Bug 354940] Re: [i915] UXA is very slow (UXA bug)
With the following Intel controller on Jaunty/9.01: 00:02.0 VGA compatible controller [0300]: Intel Corporation Mobile 915GM/GMS/910GML Express Graphics Controller [8086:2592] (rev 03) And updated kernel as recommended in http://ubuntuforums.org/showthread.php?t=1130582 Linux presto 2.6.30-02063003-generic #02063003 SMP Sat Jul 25 10:57:13 UTC 2009 i686 GNU/Linux Intel driver from PPA https://launchpad.net/~ubuntu-x-swat/+archive/x-updates/ Package: xserver-xorg-video-intel Architecture: i386 Version: 2:2.7.1-0ubuntu1~xup~1 xorg.conf Section Device Identifier Configured Video Device Driver intel Option AccelMethod exa Option EXAOptimizeMigration true Option MigrationHeuristicgreedy Option Tilingtrue I got the following results: PPracer, fullscreen 1280*800: UXA 11-15fps, EXA 25-30fps Fullscreen flash noticeably worse with UXA (tearing, dropped frames) The same ratio results (UXA giving about half frame rate and worse 2D video performance than EXA) was noted with the 2.4 Intel driver from Intrepid, Jaunty stock 2.6.3 driver, and the X-updates 2.7.1 driver. Performance with the downgraded 2.4 driver was noticeably worse (EXA). Upgrading from stock 2.6.28.15 kernel to 2.6.30 gave about a 20% improvement in framerate on ppracer. Hope this information helps someone. However, to say that a fix is released/bug resolved, when it's necessary to run an alpha of Karmic and a git version of the intel driver, is stretching a point a bit. It looks like most users will have to wait until the release of Karmic before they can watch full-screen video on intel chips (and even then, it's going to be marginal). -- [i915] UXA is very slow (UXA bug) https://bugs.launchpad.net/bugs/354940 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Retested with the following: xorg-edgers PPA intel driver Version: 2:2.8.0+git20090814.926c7e7d-0ubuntu0sarvatt~jaunty 2.6.30-02063005-generic 00:02.0 VGA compatible controller [0300]: Intel Corporation Mobile 915GM/GMS/910GML Express Graphics Controller [8086:2592] (rev 03) Due to the 2.8.0 driver EXA is no longer available, so UXA is used whatever is in the config file: (WW) intel(0): Option AccelMethod is not used #new comment line in Xorg.0/log Unfortunately, I can't confirm William Grant's test results on Karmic, above. With this combination (tested both with and without kernel modesetting) the framerate in ppracer is cut to 11-14fps, and fullscreen video is choppy. This is roughly what was achieved with 2.6.3 or 2.7.1 drivers with UXA, and is about half the EXA framerate. It seems this degradation does not apply to all Intel chipsets, since https://wiki.ubuntu.com/X/UxaTesting has users reporting improved performance.

Same problem here on my Acer Aspire One with graphic card; Intel Corporation Mobile 945GME Express Integrated Graphics Controller [8086:27ae] (rev 03) When trying the UXA it's slowing down the UNR, mousepointer is laggy. One good thing thou, is that video playback performance is improved very much, now the picture is more smooth and theres no broken parts in the video (when the scenes are moving on some part of the picture is behing a few milliseconds when im running in the other mode)! -- [i915] UXA is very slow (UXA bug) https://bugs.launchpad.net/bugs/354940 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

With driver 2:2.7.99.1+git20090519.09beee37-0ubuntu0sarvatt~jaunty, ppracer reports a rough average of 26 FPS, usually ranging between 22 and 30. So that's reasonable, seems there have been a good progress. Not sure we can close the bug, anyway it will be difficult to determine what the normal result should be. -- [i915] UXA is very slow (UXA bug) https://bugs.launchpad.net/bugs/354940 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

I've tested performances with ppracer: EXA: 25-34 FPS - average: 31 UXA: 14-22 FPS - average: 20 So there's obviously a problem! About benchmarking: I worked hard to get these simple figures because the '-a' option of ppracer, that is said to enable benchmarking, raises an error. I guess you'd get more answers if you say users to enable the Show FPS option from the game GUI (I did not think it existed). Same for phoronix: several tests don't work, and I couldn't find the right one.

Thanks, however for upstreaming purposes I'd need wgrant's reply. Also, glxgears is not a benchmark, and presenting its numbers as evidence of a performance bug will not be taken seriously. Comparisons using a game such as ppracer or phoronix would be better received. ** Changed in: xserver-xorg-video-intel (Ubuntu) Status: Incomplete = New ** Changed in: xserver-xorg-video-intel (Ubuntu) Status: New = Incomplete -- [i915] UXA is very slow (UXA bug) https://bugs.launchpad.net/bugs/354940 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Still here with 2.7.0. Good to have this PPA ot check that, thanks! I'm getting around 300 FPS instead of 750 with glxgears. I've noticed an interesting message when starting glxgears using UXA: Running synchronized to the vertical refresh. The framerate should be approximately 1/259 the monitor refresh rate. No idea about whether it could be related. Note that with the old driver, I was getting 250 FPS, and the refresh rate was 1/165!
