[PATCH AUTOSEL 5.4 21/50] drm/amd/display: Do not set optimized_require to false after plane disable

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

 



From: Sung Lee <sung.lee@xxxxxxx>

[ Upstream commit df36f6cf23ada812930afa8ee76681d4ad307c61 ]

[WHY]
The optimized_require flag is needed to set watermarks and clocks lower
in certain conditions. This flag is set to true and then set to false
while programming front end in dcn20.

[HOW]
Do not set the flag to false while disabling plane.
