drm/amdgpu: fix build_coefficients() argument

2020-12-30T10:51:04+00:00

[ Upstream commit dbb60031dd0c2b85f10ce4c12ae604c28d3aaca4 ] 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).

drm/amd/display: set minimum abm backlight level

2019-12-31T15:43:34+00:00

[ Upstream commit 2ad0cdf9e2e9e079af34af681863fa638f2ee212 ] [Why] A lot of the time, the backlight characteristic curve maps min backlight to a non-zero value. But there are cases where we want the curve to intersect at 0. In this scenario even if OS never asks to set 0% backlight, the ABM reduction can result in backlight being lowered close to 0. This particularly can cause problems in some LED drivers, and in general just looks like backlight is completely off. [How] Add default cap to disallow backlight from dropping below 1% even after ABM reduction is applied.
