Is there any documentation on the AMDGPU driver parameters?

I have a Carrizo (AMD A10-8700P Radeon R6, 10 Compute Cores 4C+6G). and am running the linux AMDGPU kernel module.


I can see there are these options:




I'm in particular interested if there is any documentation surrounding "bapm" and "powerplay", or if there are any other performance related params.


Also even though the cpu is flagged with "aperfmperf", I don't seem to get any data in "cpufreq-aperf". Is there another way I can check the cpu frequency, perhaps an amd tool or module?


Many Thanks.


Update: got the cpufreq-aperf running, loaded a bunch of tweeked ssdt's. but still keen to see documentation on the params if anyone has any links?
