[PATCH 06/10] drm/amd/pp: Implement set_power_profile_mode on smu7

[Rex Zhu]

User can set smu7 dpm pamameters through sysfs

Depending on the workloads,
user can echo "0/1/2/3/4">pp_power_profile_mode
to select 3D_FULL_SCREEN/POWER_SAVING/VIDEO/VR/COMPUTE
mode.

echo "5 * * * * * * * *">pp_power_profile_mode
to config custom mode.
"5 * * * * * * * *" mean "CUSTOM enable_sclk SCLK_UP_HYST
SCLK_DOWN_HYST SCLK_ACTIVE_LEVEL enable_mclk MCLK_UP_HYST
MCLK_DOWN_HYST MCLK_ACTIVE_LEVEL"

if the parameter enable_sclk/enable_mclk is true,
driver will update the following parameters to dpm table.
if false, ignore the following parameters.
