drm_atomic_helper_wait_for_fences — wait for fences stashed in plane state
void drm_atomic_helper_wait_for_fences ( | struct drm_device * dev, |
struct drm_atomic_state * state) ; |
For implicit sync, driver should fish the exclusive fence out from the
incoming fb's and stash it in the drm_plane_state. This is called after
drm_atomic_helper_swap_state
so it uses the current plane state (and
just uses the atomic state to find the changed planes)
