RX 480 with llvm 4.0.0svn_r290670, mesa git Tested with linux 4.9 and 4.10-rc1, happens on both. Tested with ingame settings medium and highest, happens with both. This apitrace hangs my GPU: https://haagch.frickel.club/files/stanley_linux.trace.xz Dez 29 11:21:58 c-l kernel: [drm:amdgpu_job_timedout [amdgpu]] *ERROR* ring gfx timeout, last signaled seq=6391, last emitted seq=6394 Dez 29 11:21:58 c-l kernel: [drm] IP block:gfx_v8_0 is hung!
Created attachment 128688 [details] full dmesg Apparently this didn't attach correctly when I created the bug.
Thanks for reporting this. I can reproduce the hang on rx 480 with latest mesa/llvm git. It hangs at drawcall 674985. I will investigate.
It's actually a regression in mesa, works fine with 13.0.2. After bisecting, the first bad commit is: commit ed3190b3f3a776fc8c75b1e6130a88079166d115 Author: Marek Olšák <marek.olsak@amd.com> Date: Sun Nov 13 18:41:43 2016 +0100 radeonsi: don't export ClipVertex and ClipDistance[] if clipping is disabled This is the first user of optimized monolithic shader variants. Cull distances can't be disabled by states. Tested-by: Edmondo Tommasina <edmondo.tommasina@gmail.com> Reviewed-by: Nicolai Hähnle <nicolai.haehnle@amd.com> But this doesn't seem to be actually related to the clip planes optimization because if you replay the trace with R600_DUMP_SHADERS=y, it no longer crashes. If my understanding is correct, it won't compile shaders asynchronously. Forcing num_compiler_threads = 1 in si_pipe.c also "fixes" the hang.
This should fix it: https://patchwork.freedesktop.org/patch/130844/
The game runs without hangs now. Thanks.
