drm/amd/display: implement shared PSR-SU sink validation helper

2022-04-13T13:14:22+00:00

[why] creating a generic helper for AMD specific PSR-SU sink validation. Moving the function to the power module to reference it across all OS. [how] - drop PSRSU specific sink validation helper and move to power module by reading PSR version and other PSR caps - call the new helper from linux DM (amdgpu_dm_psr) Acked-by: Pavle Kotarac Acked-by: Tom Chung Signed-off-by: David Zhang Signed-off-by: Alex Deucher

drm/amd/display: fix calculation for the pwl backlight curve

2021-02-02T17:09:46+00:00

[Why] The PWL backlight curve is used by the firmware to convert between brightness and linear PWM value. Driver has a backlight LUT, but the firmware holds a PWL curve and interpolates between points. The calculations are incorrect leading to slightly off backlight values being programmed.
