Bug 93353

i also have this on another try:
 
EE r600_shader.c:182 r600_pipe_shader_create - translation from TGSI failed !
EE r600_state_common.c:826 r600_shader_select - Failed to build shader variant (type=1) -1
EE r600_shader.c:429 tgsi_is_supported - unsupported src 1 (file 0, dimension 1)
EE r600_shader.c:182 r600_pipe_shader_create - translation from TGSI failed !
EE r600_state_common.c:826 r600_shader_select - Failed to build shader variant (type=4) -22

This could be related to the report just filed by me:
https://bugs.freedesktop.org/show_bug.cgi?id=93352

You might try running with ST_DEBUG=tgsi -- should show the failing shaders. Make sure you're on a debug build. MESA_GLSL=dump should be interesting too. [Sadly there's a 4k limit on the dumped shader code size which is likely too short for a lot of shaders...]

it look like to hapened at shader compiling time.

Each time i have a crash there are new shaders in the bin directory of the game.

And then after some crash i have all the shaders needed by the game to play the race, but the game is still crashing on benchmark and totally freeze the computer on replay with the cockpit view.

i made 3 differents attachements, i hope there is something interesting with them.

crash before the race

The errors relating to r600 indicate it's having trouble converting some TGSI shader. However those don't appear to be printed without --enable-debug. I've pushed out a fix for another assertion, so try a mesa git head build (make sure it includes commit eca8f38dcffb7), with --enable-debug, and run with ST_DEBUG=tgsi -- that should hopefully show which shader r600 is having trouble compiling.

Yesterday after compiling mesa with your commit, all was working fine on the lowest setting, but it was still crashing with cockpit view on replay with low setting.

This morning i made another mesa compilation because it was missing --enable-debug and now the game stop at launch screen with:

There is 5 new commit since yours and one have modification on shaders so maybe it's related.

I think it's not related at all with other commits, after reverting back is still not launching anymore.

I found that with R600_DEBUG=nosb the game launch and do not crash with any setting i choose.

With this setting I was finally able to complete the games benchmark! :)

Maybe it would be a good idea for you to take the offer from https://bugs.freedesktop.org/show_bug.cgi?id=93352#c20 ("Please let us know if we can assist by providing people working on driver issues a copy of the title") - I'm sure this will speed up debugging a lot.

Not that this is the proper channel for this, but I replied to that offer here:
