I have noticed that my GPU fans start running at high speed after some time.
Investigating, I see:
# cat /sys/kernel/debug/dri/0/amdgpu_pm_info
[ mclk ]: 1425 MHz
[ sclk ]: 990 MHz
[GPU load]: 100%
Of course I am not running any graphics intensive programs and radeontop
confirms <1% load. Even shutting down Xorg altogether doesn't help. It may be
related to dpms going to "off" state, the last time it happened while the
monitors were off, or possibly just as they were switching off. I will try to
collect additional data points. Nothing suspicious shows in logs. Powerplay
seems to work fine until the issue occurs. Afterwards, I can manually lower
clocks, but load stays 100%. Side note: dpms transitions seem to reset the
manual power_dpm_force_performance_level back to auto and hence high clock.
