[PATCH v2 18/22] drm/msm/dpu: move pipe_hw to dpu_plane_state

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

 



In preparation to adding fully virtualized planes, move struct
dpu_hw_pipe instance from struct dpu_plane to struct dpu_plane_state, as
it will become a part of state (allocated during atomic check) rather
than part of a plane (allocated during boot).
