Bug ID: 98905
Summary: XFX Radeon RX 480 XXX OC GPU hangs in games with
"auto" power_dpm_force_performance_level
Product: DRI
Version: unspecified
Hardware: Other
OS: All
Status: NEW
Severity: normal
Priority: medium
Component: DRM/AMDgpu
Assignee: dri-devel at lists.freedesktop.org
Reporter: haagch at frickel.club
I've had this across several applications and several kernel/mesa/llvm versions
and I'm not sure I get everything here right, but here it goes.
Most easily I can reproduce the GPU hang on SOMA when starting a new game - it
will hang while the intro video plays or shortly after, in the game - other and
very demanding games work without hangs.
It would hang like this:
[Di Nov 29 19:46:21 2016] [drm:amdgpu_job_timedout [amdgpu]] *ERROR* ring gfx
timeout, last signaled seq=3374996, last emitted seq=3374998
[Di Nov 29 19:46:21 2016] [drm] IP block:5 is hang!
Just now is the first time it actually recovered, usually I need to hard reset
the PC.
Now this GPU is factory overclocked a little bit:
/sys/class/drm/card0/device/pp_dpm_sclk
0: 300Mhz
1: 608Mhz
2: 910Mhz
3: 1077Mhz
4: 1145Mhz
5: 1191Mhz
6: 1236Mhz
7: 1288Mhz *
I am reasonably confident that when I set a power level with this command:
echo manual > /sys/class/drm/card0/device/power_dpm_force_performance_level
echo 7 > /sys/class/drm/card0/device/pp_dpm_sclk
the GPU will not hang while the power level is fixed.
Therefore I think that the GPU hang is related to switching between power
levels.
It's possible that this problem is specific to this factory overclocked model.
