Bug 257294 – x11-libs/libdrm-2.4.4: slow 3D performance on intel 965gm

• Product: Gentoo Linux
• Status: RESOLVED UPSTREAM

[Description Uros 2009-02-01 22:14:26 UTC]

Something isn't working right with x11-libs/libdrm-2.4.4. on my end.

Using :
- x11-libs/libdrm-2.4.4
- x11-drivers/xf86-video-intel-2.6.1
- x11-base/xorg-server-1.5.3-r1
- media-libs/mesa-7.3
- EXA accel method
- DRI

With x11-wm/compiz-0.7.8-r2 on intel 965gm, and with libdrm-2.4.3. performance is mostly OK, but when switching to libdrm-2.4.4. and rebuilding all mentioned packages, I'm getting such a sluggish performance that it's unusable for daily use.

Too many API modifications from 2.4.3?

Reproducible: Always

A couple things :

1) please attach your xorg.conf
2) please attach Xorg.0.log and dmesg output from with both libdrm 2.4.3 and 2.4.4
3) with 2.4.4, try setting AccelMethod to UXA in your xorg.conf's Device section

Thanks

Ehh.. my bad. I guess reboot was needed after upgrading to libdrm-2.4.4 for changes to take effect or something -- restarting xorg wasn't enough.

After reboot, it works with exa/uxa, without slowdowns.

Sorry.

[Comment 9 Rémi Cardona (RETIRED) 2009-02-02 23:47:45 UTC]

Heh, thanks for the follow up :)

It is indeed something many users have noticed: Intel hardware and drivers often need a full restart (sometimes even with a few seconds of *complete* poweroff) to work properly... Not much we can do about this.

Cheers

Soo.. I'm back with this problem -- only now, on the next level.

After restarting/reloading xorg (returning from suspend-to-ram for instance), 3D accel. gets lost somewhere.. same sluggish performance as described in initial bug report (switching from  2.4.3 to 2.4.4 without rebooting) -- untill reboot that is.

And the fun part? It works as intended with libdrm-2.4.3 (after rebuilding everything and rebooting).. sometimes..

With libdrm-2.4.3 system experiences such simptoms as described at https://bugs.freedesktop.org/show_bug.cgi?id=17807 -- random square blip under mouse cursor, touchpad working every other input dead after returning from suspend-to-ram.

Trading one annoying problem for another.

All related logs are already attached as I understand, or do you need something else?

Is it even libdrm related?

[Comment 11 Rémi Cardona (RETIRED) 2009-02-03 20:05:19 UTC]

No, there's not much else I can do. Let's track this upstream.

Thanks

[Comment 12 Rémi Cardona (RETIRED) 2009-02-03 20:06:29 UTC]

Erf, I hadn't realised the upstream bug you linked wasn't yours.

Please open a bug in FreeDesktop's bugzilla and add "[e-mail]" so I can keep track of the issue.

Thanks
