It seems reasonable, now I have to use it manually, or with my own scripts and daemons.
However, I think it is important that this cannot be enabled by default and a good help is needed for this setting in the configuration file.
Is your feature request related to a problem? Please describe. AMDGPU driver aggressively force power saving when FPS is limited due low GPU load. More info here https://gitlab.freedesktop.org/drm/amd/-/issues/1500 (doesn't fixed for 3+ years)
Looks like driver doesn't use 3D_FULL_SCREEN profile at all, because it can't detect what full screen is due compositor or whatever.
Describe the solution you'd like Add option to set pp_power_profile_mode in config along with power_dpm_force_performance_level.
Right now we have only amd_performance_level=high to fix issues with powersaving, but it force GPU use maximum clocks even with low GPU load and causes GPU to generate too much heat.
Using 3D_FULL_SCREEN power profile will fix this issue along with powersaving problems.
for example
amd_power_profile=3D_FULL_SCREEN will be fine
Describe alternatives you've considered You can see all available profiles here
# cat /sys/class/drm/card1/device/pp_power_profile_mode
And see current used profile marked by *
You also can manually set profile, for example
# echo 1 > /sys/class/drm/card1/device/pp_power_profile_mode
set 3D_FULL_SCREEN power profile
