    Is there any documentation on the AMDGPU driver parameters?

      Hi,

       

      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:

       

      aspm,audio,bapm,benchmark,cg_mask,deep_color,disable_cu,disp_priority,dpm,exp_hw_support,gartsize,hw_i2c,ip_block_mask,lockup_timeout,msi,pcie_gen2,pcie_gen_cap,pcie_lane_cap,pg_mask,powercontainment,powerplay,runpm,sched_hw_submission,sched_jobs,smc_load_fw,test,vm_block_size,vm_debug,vm_fault_stop,vm_size,vramlimit

       

      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?
