Created attachment 127138 [details] dmesg with gpu hang XFX Radeon RX 480 XXX OC, latest mesa git and llvm svn. Running unigine heaven for a while hangs the gpu like this: Okt 08 10:31:14 c-l kernel: [drm:amdgpu_job_timedout] *ERROR* ring gfx timeout, last signaled seq=42581, last emitted seq=42583 Okt 08 10:31:14 c-l kernel: [drm] IP block:1 is hang! Okt 08 10:31:14 c-l kernel: [drm] IP block:5 is hang! I tried bisecting and landed on 4be051aeb3964146d3922238fff0ed1e4a9656d1 "drm/amd/powerplay: use smu7 hwmgr to manager polaris10/11" but I'm not 100% confident I caught every bad commit because sometimes unigine heaven needs to run for several minutes before the hang happens and this commit is not trivial to revert.
Does NOT happen with 4.9-rc1 even though this commit is in it. Either my bisect result is just wrong or it only happens in combination with another commit not yet in 4.9-rc1.
Created attachment 127334 [details] gpu hang dmesg with counter strike: global offensive To document this: csgo ran fine, although very slow with stock 4.9-rc1. I did not try for very long, so perhaps it would still have happened after a while. The performance issue was identified to be caused by 87744ab3832b83ba71b931f86f9cfdb000d07da5 After reverting this commit on 4.9-rc1, I still do not get GPU hangs with unigine heaven, but I start seeing GPU hangs with csgo. Maybe not the same issue, but it doesn't happen on 4.8.
Created attachment 127394 [details] csgo gpu fault and hang on amd-staging-4.7 I just don't know anymore. There seems to be a lot of brokenness on Polaris (or maybe just on my XFX Radeon RX 480 XXX OC model) right now. This is a GPU fault + gpu hang that is caused by the native version of csgo on amd-staging-4.7.
Created attachment 127395 [details] wine+nine csgo gpu fault and hang on stock 4.8 This is a GPU fault + hang I got on stock 4.8 when I tried the windows version of csgo with nine. The native version of csgo runs normally on stock 4.8.
unigine heaven and csgo work fine with amdgpu-staging-4.7 f9c58ccc03147e652284f06053b089eca957e1e1 with drm-next-4.10 (with 87744ab3832b83ba71b931f86f9cfdb000d07da5) reverted for performance, unigine heaven works (I think), but csgo causes gpu hangs.
Created attachment 127496 [details] wine+nine csgo gpu fault and hang amd-staging-4.7 Wait, this amd-staging-4.7 revision doesn't work well either. Tried with csgo nine and it fails too.
On stock 4.8 again and native csgo and csgo with nine run both fine - on auto (high) graphics settings. It appears there is something with the lowest settings that breaks the driver on both the native version and the nine version. I think I the original bug here is solved, because unigine heaven has been running stable on both amd-staging-4.7 and drm-next-4.9/4.10-wip, and that the csgo and soma bug is something else).
I'm relatively sure that my bad GPU caused all of this (maybe except the first issue which was soon solved). *** This bug has been marked as a duplicate of bug 98905 ***
