[PATCH 6.1 142/193] drm/amd/display: Calculate output_color_space after pixel encoding adjustment

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

 



From: Joshua Ashton <joshua@xxxxxxxxx>

commit 79601b894849cb6f6d6122e6590f1887ac4a66b3 upstream.

Code in get_output_color_space depends on knowing the pixel encoding to
determine whether to pick between eg. COLOR_SPACE_SRGB or
COLOR_SPACE_YCBCR709 for transparent RGB -> YCbCr 4:4:4 in the driver.

v2: Fixed patch being accidentally based on a personal feature branch, oops!

Fixes: ea117312ea9f ("drm/amd/display: Reduce HDMI pixel encoding if max clock is exceeded")
