[PATCH v3 05/27] drm/msm/dpu: move pipe_hw to dpu_plane_state
Dmitry Baryshkov
dmitry.baryshkov at linaro.org
Fri Feb 3 18:21:10 UTC 2023
In preparation to adding fully virtualized planes, move struct
dpu_hw_sspp instance from struct dpu_plane to struct dpu_plane_state, as
it will become a part of state (variable, changes during runtime) rather
than part of a plane (ideally should be statically allocated during boot).
The sspp pointer is set at the dpu_plane_reset(), since this is the
function which allocates the state. Once we have fully virtual
plane<->SSPP relationship, the SSPP will be allocated dynamically in the
dpu_plane_atomic_check() function.
