[PATCH 25/31] drm/amd/display: Query for update plane type.

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

 



From: Andrey Grodzovsky <Andrey.Grodzovsky@xxxxxxx>

Use DC interface to query for plane update type
so in case of FULL update you flush any outstanding
commits.
