I was using power-profiles-daemon version 0.23 in balanced mode.
I also tested TLP, and vanilla kernel without any power daemons running.
Without any daemons I use the following:
energy_performance_preference: balance_power
scaling_driver: amd-pstate-epp
scaling_governor: powersave
Thanks as long as it can reproduce in 'balanced' mode that should exclude PPD
from being the cause and it most likely a pure kernel bug.
I'm curious if you have a PSR supported panel. Does setting
amdgpu.dcdebugmask=0x10 on your kernel cmdline help? This force disables PSR.
Another flag to try is amdgpu.dcdebugmask=0x800, which allows PSR but disables
idle power optimizations. I wonder if that may be causing extra latency.
