[PATCH 10/50] drm/amd/display: Implement bias and scale pre scl
Fangzhi Zuo
Jerry.Zuo at amd.com
Wed Jul 10 19:36:27 UTC 2024
From: Relja Vojvodic <relja.vojvodic at amd.com>
why:
New scaler needs the input to be full range color space. This will also fix
issues that come up due to not having a predefined limited color space matrix
for certain color spaces
how:
Use bias and scale HW to expand the range of limited color spaces to full
before the scaler
