drm/amd/display: Disable PSRSU when DSC enabled on the specific sink

2022-07-12T20:50:29Z

[Why] Some specific sink is not able to support PSRSU when DSC is turned on. For this case, fall-back to use PSR1. Reviewed-by: Anthony Koo Acked-by: Solomon Chiu Signed-off-by: Robin Chen Tested-by: Daniel Wheeler Signed-off-by: Alex Deucher

drm/amd/display: add shared helpers to update psr config fields to power module

2022-06-06T18:42:33Z

[why] Currently the amdgpu DM psr configuration parameters are hardcoded before feeding into the DC helper to setup PSR. We would define a helper which is to calculate parts of the psr config fields to avoid hard-coding. [how] To make helper shareable, declare and define the helper in the module_helper, to set/update below fields: - psr remote buffer setup time - sdp tx line number deadline - line time in us - su_y_granularity - su_granularity_required - psr_frame_capture_indication_req - psr_exit_link_training_required add another helper to check given the stream context, if there is only one stream and the output is eDP panel connected. changes in v2: ------------------ - add detailed comment for how psr setup time is calculated as per eDP 1.5 spec Cc: Chandan Vurdigerenataraj Signed-off-by: David Zhang Acked-by: Leo Li Reviewed-by: Harry Wentland Signed-off-by: Alex Deucher

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

2022-04-13T13:14:22Z

[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

2021-02-02T17:09:46Z

[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.
