[PATCH 4/8] amdgpu/pm: Powerplay API for smu , changed 9 pm power functions to use API
Darren Powell
darren.powell at amd.com
Sat Dec 19 00:48:27 UTC 2020
Modified Files
smu_get_power_limit() - modifed arg0 to match Powerplay API get_power_limit
smu_set_power_limit() - modifed arg0 to match Powerplay API set_power_limit
smu_sys_get_pp_table() - modifed signature to match Powerplay API get_pp_table
smu_get_power_num_states() - modifed arg0 to match Powerplay API get_pp_num_states
smu_get_current_power_state() - modifed arg0 to match Powerplay API get_current_power_state
smu_sys_get_pp_feature_mask() - modifed signature to match Powerplay API get_ppfeature_status
smu_sys_set_pp_feature_mask() - modifed arg0 to match Powerplay API set_ppfeature_status
Other Changes
added 7 above smu Powerplay functions to swsmu_dpm_funcs
removed special smu handling of above functions and called through Powerplay API
