[PATCH 28/30] drm/amd/display: Add swizzle visual confirm mode

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

 



From: Po-Ting Chen <robin.chen@xxxxxxx>

[Why]
To support a new visual confirm mode: swizzle to show the specific
color at the screen border according to different surface swizzle mode.
Currently we only support the Linear mode with red color.
