Description Sylvain BERTRAND 2017-07-04 09:07:34 UTC

steamos beta (debian), mesa 17.1.2, linux kernel 4.12
Dota2 randomly crashes: Jul 4 10:32:45 steamos kernel: [ 1728.851665] traps: Globpool1[1352] general protection ip:7f6a0a2a149 sp:7f6a1e9ea790 error:0 in libparticles.so[7f6a0a110000+579000]
If I run the game with the radeon linux module instead of the amdgpu linux module, I don't get any crash, but the game runs _significantly_ slower.

Comment 1 Sylvain BERTRAND 2017-07-05 15:24:27 UTC

I was wrong, it's worse: linux 4.12 amdgpu and radeon do random crash dota2 the same way (in libparticles). Both 4.12 modules are _significantly_ faster than the stable 4.11 radeon while not crashing.

Comment 2 Alex Deucher 2017-07-05 15:46:27 UTC

Is this a regression?  If so, did you also change the mesa version you are using?

Comment 3 Sylvain BERTRAND 2017-07-05 17:29:25 UTC

Same mesa binaries from up-to-date "beta" steamos: 17.1.2.

As far as I tested it, I cannot even play one dota2 game without the game
program randomly crashing in dota2 libparticles (radeon or amdgpu).

Comment 4 Sylvain BERTRAND 2017-08-14 17:56:07 UTC

Running dota2 vulkan with git mesa and git llvm now. The crash seems gone. I'll play a bit and we will see.

Comment 5 Sylvain BERTRAND 2017-09-24 18:19:58 UTC

Have been playing for days and hours to dota2-vulkan

No crash whatsoever, just significantly slower than gl rendering and what seem rendering bugs.

closing.

Comment 6 Bas Nieuwenhuizen 2017-09-24 18:24:22 UTC

So what I'm still missing is (1) was the original bug using GL or Vulkan? (2) if GL in (1), does the issue still occur on GL?
