[PATCH 53/81] drm/amd/display: Attach surface to dm_plane_state.

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

 



From: Andrey Grodzovsky <Andrey.Grodzovsky@xxxxxxx>

Attach surface to state.
Remove Create surface from commit.
Propogate any surface creation and initialization error back to atomic_check caller.
clean outdated code in check and commit.
