drm/amd/display: Fix mismatch type comparison

2025-05-29T09:02:37+00:00

[ Upstream commit 26873260d394b1e33cdd720154aedf0af95327f9 ] The mismatch type comparison/assignment may cause data loss. Since the values are always non-negative, it is safe to use unsigned variables to resolve the mismatch.

drm/amd/display: Use SDR white level to calculate matrix coefficients

2024-09-18T20:15:06+00:00

[WHY] Certain profiles have higher HDR multiplier than SDR white level max which is not currently supported. [HOW] Use SDR white level when calculating matrix coefficients for HDR RGB MPO path instead of HDR multiplier.
