i915 driver stack slow 3D performance on multilib
 
my latest mystery with the i915 driver stack: on my Clarkdale machine (i965) Quake 3 runs with 1 frame per second. It used to be OK. For some reason it selects the software renderer. It is a 32 bit application running with multilibs.

I can't tell which of the recent upgrades might be responsible: kernel, xorg, libdrm, mesa or other?

It appears in 64 bit everything is working OK (with the exception of the other i915 issues I'm having).

Code:

guest@arnold$ grep Renderer .q3a/baseq3/q3config.cfg

I tried upgrading mesa to 7.11 but could not get the Slackbuild to work.

Oh, btw, the same software config works great on another machine with nvidia blob.

Does anyone have a hint (other than to dump intel graphics)?

Thanks.

What does your GLXINFO output show? Also, post your xorg.conf as well.

ok, here's the complete glxinfo output (in addition to the two lines above). I verified the issue with a single screen and no xorg.conf (but it happens with dual monitor setup, too).

I finally managed to build mesa 7.11 (cf. other thread) but that didn't help. now only xorg itself (at least xf68-video-intel) needs upgrading to be on par with the intel Q3 recommendation. However, I have the feeling all that is barking up the wrong tree.

adamk75 08-20-2011 11:50 AM

Well, as you say in the first post, this only happens with 32-bit software, right? Sounds to me like the 32-bit Mesa libraries are not installed/working properly. Did you confirm the 32-bit mesa package was installed initially, and that when you built Mesa 7.11, you had it build the 32-bit libraries and drivers?

Martinus2u 08-20-2011 01:18 PM

yes. Just to rule out any side-effects through multilib i built llvm and mesa-7.11-i486 on my only true 32 bit installation, a P3 which took a few hours for the compilation. ;-)

I then converted the package to mesa-compat32-7.11-x86_64 and installed it together with mesa-7.11-x86_64 on the target machine.

Come to think of it, the software emulation works fine (albeit slow). It just seems the 32 bit application does not get the option of a hardware rasterizer. So maybe the issue is on the turf of the intel driver (which wouldn't totally surprise me) but i have no idea how it all hangs together.

adamk75 08-20-2011 02:47 PM

Before running quake3, set the LIBGL_DEBUG=verbose in a terminal, and then run the game. The GL library should spit out a few errors as to why it's falling back to the software rasterizer.

Thanks, I'm on to something. The relevant output was:
Code:

libGL error: dlopen /usr/lib/xorg/modules/dri/i965_dri.so failed (libpciaccess.so.0: cannot open shared object file: No such file or directory)
libGL error: unable to load driver: i965_dri.so

that indicates to me that OpenGL is looking for a certain set of libraries that seem to be missing. Google fodder. ;-)

Martinus2u 08-20-2011 04:55 PM

OK, problem solved. Created a libpciaccess-compat32-0.12.1-x86_64-1.txz, installed it, and everything works as before. Thanks Adam. :-)

<deep_voice>
Perfect

If libpciaccess-compat32 isn't installed by default via AlienBob's multilib instructions, you may want to drop him a note, suggesting he include it.
