[PATCH 3/8] amdgpu/pm: Powerplay API for smu , changed 6 pm hwmon fan functions to use API
Darren Powell
darren.powell at amd.com
Sat Dec 19 00:48:26 UTC 2020
Modified Functions
smu_set_fan_speed_rpm() - modifed arg0 to match Powerplay API set_fan_speed_rpm
smu_get_fan_control_mode() - modifed signature to match Powerplay API get_fan_control_mode
smu_set_fan_control_mode() - modifed signature to match Powerplay API set_fan_control_mode
smu_get_fan_speed_percent() - modifed signature to match Powerplay API get_fan_speed_percent
smu_set_fan_speed_percent() - modifed signature to match Powerplay API set_fan_speed_percent
smu_get_fan_speed_rpm() - modifed arg0 to match Powerplay API get_fan_speed_rpm
Other Changes
added 6 above smu fan Powerplay functions to swsmu_dpm_funcs
removed special smu handling of above functions and called through Powerplay API
