[RFC PATCH 28/40] drm/amd/display: set sdr_ref_white_level to 80 for out_transfer_func

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Joshua Ashton <joshua@xxxxxxxxx>

Otherwise this is just initialized to 0.

This needs to actually have a value so that compute_curve can work
for PQ EOTF.
