Running the attached test using Amber (https://github.com/google/amber): amber -d unreachable-barrier-in-loops.amber should lead to the test passing. Instead, I find that my system immediately locks up. I believe it is a whole system freeze, rather than just a display freeze. Build: Mesa 19.2.0-devel (git-a110a8090d) (Debug) Device: Radeon RX Vega I can reproduce the failure with your Mesa HEAD, however current Mesa master branch (git-4379dcc12d) passes the test. Please re-test. Operating System: Ubuntu 18.04 Linux kernel: 5.0.0-23-generic Mesa: 19.3.0-devel (git-4379dcc12d) GPU: AMD RADV POLARIS10 (LLVM 8.0.1) (In reply to Alastair Donaldson from comment #1) > Running the attached test using Amber (https://github.com/google/amber): > > amber -d unreachable-barrier-in-loops.amber > > should lead to the test passing. > > Instead, I find that my system immediately locks up.

I have enabled amdgpu.gpu_recovery=1 functionality to avoid it. > Build: Mesa 19.2.0-devel (git-a110a8090d) (Debug) > Device: Radeon RX Vega I can confirm that the test passes for me on master, so I guess we should close this issue; I'll open another one if it turns out the issue still persists and can be exposed by a different test. Thanks for the advice regarding GPU recovery. |
