           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.

    NOTE: This is a candidate for the 7.9 and 7.10 branches.

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:

If you run with MESA_GLSL=nopt, does it still crash?

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.

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.

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?

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.

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?

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. Thanks
