Comment # 31
on bug 111482
from Shmerl
I can confirm, that at 2560x1440 / 144 Hz, after suspend / resume, setting
"high" in /sys/class/drm/card0/device/power_dpm_force_performance_level stops
flickering that starts after resume, and then setting "low" there still keeps
it flickering free, while dropping MCLK and power consumption to what you
expect from a normal idle level!
You can check that with:
sudo cat /sys/kernel/debug/dri/0/amdgpu_pm_info
So it means the card can handle it after all, but somehow doesn't dynamically
adjust to that state.
Can anyone from AMD please comment on this situation?
