[PATCH 8/8] amdgpu/pm: Powerplay API for smu , updates to some pm functions
Darren Powell
darren.powell at amd.com
Sat Dec 19 00:48:31 UTC 2020
Modified Functions
smu_sys_set_pp_table() - modifed signature to match Powerplay API set_pp_table
smu_force_performance_level() - modifed arg0 to match Powerplay API force_performance_level
smu_od_edit_dpm_table() - modifed arg0 to match Powerplay API odn_edit_dpm_table
Other Changes
smu_od_edit_dpm_table() - removed call to task(READJUST_POWER_STATE) after COMMIT_TABLE,
now handled in calling function
amdgpu_set_power_dpm_force_performance_level() - now checks thermal for swsmu systems before trying to change level
amdgpu_set_pp_od_clk_voltage() - now attempts to set fine_grain_clock_vol before swsmu edit dpm table
