drm / i915 performance problems

drm / i915 performance problems

[Knut Petersen]

Hi David!

My current system is based on openSuSE 10.2, kernel 2.6.22.6 is used.
As support for that distribution is discontinued, I had a look at
openSuSE 11.1
and tried some of the new kernels. I found serious  performance regressions
using the current kernels

First a short descrition of the relevant hardware:

mainboard: Aopen i915Gmm-hfs,
RAM: 2 GB
cpu: Pentium M  1.86GHz.
video: built in i915GM
00:00.0 Host bridge: Intel Corporation Mobile 915GM/PM/GMS/910GML
Express Processor to DRAM Controller (rev 04)
00:02.0 VGA compatible controller: Intel Corporation Mobile
915GM/GMS/910GML Express Graphics Controller (rev 04) (prog-if 00 [VGA])
00:02.1 Display controller: Intel Corporation Mobile 915GM/GMS/910GML
Express Graphics Controller (rev 04)

Test results:

glxgears: 1045 fps / 30% cpu usage (opensuse 10.2, kernel 2.6.22.6,
smooth desktop and glxgears operation)
glxgears: 925 fps / 35% cpu usage (opensuse 11.1, kernel 2.6.22.6,
smooth desktop and glxgears operation)
glxgears: 900 fps / 45% cpu usage (opensuse 11.1, kernel 2.6.27.29,
smooth desktop and glxgears operation)

glxgears: 210 fps / 8% cpu usage (opensuse 11.1, kernel 2.6.31-rc6,
Tiled buffers, jerky desktop and glxgears operation)
glxgears: 230 fps / 8% cpu usage (opensuse 11.1, kernel 2.6.31-rc6,
Tiling disabled, jerky desktop and glxgears operation)

glxgears: 280 fps / 100% cpu usage (opensuse 11.1, kernel 2.6.31-rc6,
DRI disabled in kernel, smooth desktop and glxgears operation)
 
With "jerky operation" in the table above I want to express, that
desktop and glxgears drawing operation seems to happen in
several bursts a second. Because of that the desktop performance is
annoying enough to be unusable.

Xorg.0.log tells me: "Failed to set tiling on [front|back|depth] buffer:
Invalid argument". As disabling tiling in the older kernels
results in similar performance drops, I believe that the inability to
use tiled buffers is responsible for the low glxgears fps numbers.

Any ideas how to solve that problem?

 Knut

I bet some people'd love to know what X.org version and intel drv
version you're using.

Also, if you're having KMS enabled or not.

Well, I doubt that Xorg is the problem as it perfectly works with older
versions of the kernel.

The problem is always present, no matter if
- KMS is enabled or not
- the agp/drm drivers are compiled as a module or compiled into the kernel
- vesafb is used or not
- tile blitting is enabled in framebuffer config space or not

BTW: kernel 2.6.30.4 performs as bad as 2.6.31-rc6.

Hi.
Sorry if I jump in but as a former Opensuse 11.1 user I may have some
information. The problem is that the X.org version shipped with that
distro works fine only with 2.6.27.x kernels, regardless of the KMS
use.

If you want to use a newer kernel, you shoud get a 2.6.31-rc version
and a newer userspace. Please have a look at
http://bugzilla.kernel.org/show_bug.cgi?id=12950 .

If I remember correctly the solution was to add this repository:

    http://download.opensuse.org/repositories/X11:/XOrg/openSUSE_11.1/

to the repository list and then perform an update. Sorry but I left
Opensuse some months ago and my memory isn't helping a lot...

Hope this helps. Regards,
Fabio

No, it does not help too much. I  updated to the  software provided there
and the result is a X  server that crashes during startup ... :-(

Which X server is supposed to work with 2.6.30 (++) kernels on i915GM
hardware?

Your X server and the intel driver seems to be too old. Use the X server
1.6.2 rc1 with intel driver 2.7.0 and see if it works.

David.

Re: drm / i915 performance problems

[Fabio Comolli]

Hi.
My config is:

* X.org v. 1.6.3
* intel driver v. 2.7.99.902 (2.8-pre)
* intel-dri v.7.5
* mesa v. 7.5
* kernel v.2.6.31-rc6 with KMS

on an eeePC 900 with very good performance. Userspace is now ArchLinux.

Regards,
Fabio

I'm also a former OPENSUSE user and I also used the repository above, and had best success when I updated the packages by going into the view for the repository itself.

Perhaps try selecting the packages like that and also make sure you update all the DRM and Mesa packages.

Hope this helps.
