drm_atomic_crtc_for_each_plane

#define drm_atomic_crtc_for_each_plane	(		plane,
			crtc
	)		drm_for_each_plane_mask(plane, (crtc)->dev, (crtc)->state->plane_mask)

drm_atomic_crtc_for_each_plane - iterate over planes currently attached to CRTC @plane: the loop cursor @crtc: the CRTC whose planes are iterated

This iterates over the current state, useful (for example) when applying atomic state after it has been checked and swapped. To iterate over the planes which will be attached (more useful in code called from &drm_mode_config_funcs.atomic_check) see drm_atomic_crtc_state_for_each_plane().

drm_atomic_crtc_state_for_each_plane

#define drm_atomic_crtc_state_for_each_plane	(		plane,
			crtc_state
	)		drm_for_each_plane_mask(plane, (crtc_state)->state->dev, (crtc_state)->plane_mask)

drm_atomic_crtc_state_for_each_plane - iterate over attached planes in new state @plane: the loop cursor @crtc_state: the incoming CRTC state

Similar to drm_crtc_for_each_plane(), but iterates the planes that will be attached if the specified state is applied. Useful during for example in code called from &drm_mode_config_funcs.atomic_check operations, to validate the incoming state.

drm_atomic_crtc_state_for_each_plane_state

#define drm_atomic_crtc_state_for_each_plane_state	(		plane,
			plane_state,
			crtc_state
	)

Value:

    drm_for_each_plane_mask(plane, (crtc_state)->state->dev, (crtc_state)->plane_mask) \
        for_each_if ((plane_state = \
                  __drm_atomic_get_current_plane_state((crtc_state)->state, \
                                   plane)))

drm_atomic_crtc_state_for_each_plane_state - iterate over attached planes in new state @plane: the loop cursor @plane_state: loop cursor for the plane's state, must be const @crtc_state: the incoming CRTC state

Similar to drm_crtc_for_each_plane(), but iterates the planes that will be attached if the specified state is applied. Useful during for example in code called from &drm_mode_config_funcs.atomic_check operations, to validate the incoming state.

Compared to just drm_atomic_crtc_state_for_each_plane() this also fills in a const plane_state. This is useful when a driver just wants to peek at other active planes on this CRTC, but does not need to change it.
