Summary: GPU lockup in Team Fortress 2 Product: Mesa Version: git Platform: x86-64 (AMD64) OS/Version: Linux (All) Status: NEW Severity: normal Priority: medium Component: Drivers/Gallium/r600 AssignedTo: dri-devel@lists.freedesktop.org ReportedBy: Enrico_m@gmx.de
After updating mesa to current git I always get a GPU lockup when the game is about to start. After git bisect I got the following commit:
commit 18dcbd358f1d4fd5e4a40fa26c6d3bf99485884e Author: Tom Stellard tstellar@gmail.com Date: Sun Mar 27 01:17:43 2011 -0700
prog_optimize: Fix reallocating registers for shaders with loops
Registers that are used inside of loops need to be considered live starting with the first instruction of the outermost loop.

--- Comment #3 from Sven Arvidsson sa@whiz.se 2011-05-16 12:47:38 PDT --- I'm having the same problem with Left 4 Dead on:
System environment: -- system architecture: 32-bit -- Linux distribution: Debian unstable -- GPU: REDWOOD -- Model: XFX Radeon HD 5670 1GB -- Display connector: DVI -- xf86-video-ati: 6.14.1 -- xserver: 1.10.1 -- mesa: git-51095f7 -- drm: 2.4.25 -- kernel: 2.6.39-rc7
Reverting the commit mentioned above works.
The apitrace uploaded here might be useful to reproduce the hang: http://dl.dropbox.com/u/28577999/l4d.trace.7z

--- Comment #4 from Tom Stellard tstellar@gmail.com 2011-05-17 21:21:18 PDT --- If you run with MESA_GLSL=nopt, does it still crash?
https://bugs.freedesktop.org/show_bug.cgi?id=36812
--- Comment #5 from Sven Arvidsson sa@whiz.se 2011-05-19 11:16:03 PDT --- With nopt it's even worse, I get a GPU hang and this error on the terminal "EE r600_pipe.c:429 r600_get_param - r600: unknown param 45" when I try to start the game.

--- Comment #6 from Enrico_m@gmx.de 2011-05-30 06:47:14 PDT --- Here it also got worse With MESA_GLSL=nopt -> The game does not show the menu anymore and the GPU does not reset (systems frozen).
If there is anything I could do to help debug this issue (test patches or add more traces), please let me know.

--- Comment #7 from Tom Stellard tstellar@gmail.com 2011-05-31 02:21:06 PDT --- With MESA_GLSL=nopt the code that was changed by the bisected commit is not being executed, so I think the real problem might be somewhere else. I guess you could try bisecting again with MESA_GLSL=nopt and maybe you'll come up with a different bad commit.

I might try this. Enrico, do you remember what the good revision you used for the bisect was, 7.10?

--- Comment #9 from Sven Arvidsson sa@whiz.se 2011-06-03 13:54:28 PDT --- I noticed that a few piglit tests causes GPU hang/resets when run with MESA_GLSL=nopt. Is this to be expected or is it worth to file bugs?
The failing tests are glsl-fs-atan-2, glsl-fs-lots-of-tex, glsl-orangebook-ch06-bump and possibly others. They run without problems if nopt isn't used.

--- Comment #10 from Sven Arvidsson sa@whiz.se 2011-06-11 10:35:22 PDT --- There's been a few hang-related fixes in git master over the last days. I can no longer reproduce the TF2 hang, or the hangs in piglit with nopt.
Enrico, can you re-test to be sure it has been fixed?

--- Comment #11 from Enrico_m@gmx.de 2011-06-13 15:10:23 PDT --- Yes, this bug is fixed. No more GPU lockups. The game does not run with MESA_GLSL=nopt yet (something about "missing vertex shader" and "EE r600_shader.c:145 r600_pipe_shader_create - translation from TGSI failed !"), but that's another story.
