Comme= nt # 31 on bug 11148= 2 from = Shmerl 
I can confirm, that at 2560x1440 / 144 Hz, after suspend / res=
ume, 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!=20

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 dynamical=
ly
adjust to that state.

Can anyone from AMD please comment on this situation?
