2020-12-23T20:01:47Z

[Why] Need driver to pass values of backlight ramp start and ramp reduction so that intensity can be ramped down appropriately. [How] Using abm_parameters structure to get these values from driver. Signed-off-by: Rizvi Acked-by: Bindu Ramamurthy Signed-off-by: Alex Deucher

drm/amd/display: Modify the hdcp device count check condition

2020-12-23T20:01:34Z

[why] Some MST display may not report the internal panel to DEVICE_COUNT, that makes the check condition always failed. [how] To update this condition with the reported device count + 1 (because the immediate repeater's internal panel is possibly not included in DEVICE_COUNT) Signed-off-by: Martin Tsai Acked-by: Bindu Ramamurthy Signed-off-by: Alex Deucher

drm/amd/display: Fix OGAM LUT calculation precision

2020-12-15T16:34:35Z

[Why] The OGAM LUT precision was accumulating too much error in the higher end. [How] Instead of calculating all points of the LUT in relation to the previous ones, perform a full calculation in one of the intermediate segments to stop error propagation.

drm/amdgpu: fix build_coefficients() argument

2020-11-02T01:02:01Z

gcc -Wextra warns about a function taking an enum argument being called with a bool: drivers/gpu/drm/amd/amdgpu/../display/modules/color/color_gamma.c: In function 'apply_degamma_for_user_regamma': drivers/gpu/drm/amd/amdgpu/../display/modules/color/color_gamma.c:1617:29: warning: implicit conversion from 'enum ' to 'enum dc_transfer_func_predefined' [-Wenum-conversion] 1617 | build_coefficients(&coeff, true); It appears that a patch was added using the old calling conventions after the type was changed, and the value should actually be 0 (TRANSFER_FUNCTION_SRGB) here instead of 1 (true).
