Macro Definition Documentation

drm_atomic_for_each_plane_damage

#define drm_atomic_for_each_plane_damage	(		iter,
			rect
	)		while (drm_atomic_helper_damage_iter_next(iter, rect))

drm_atomic_for_each_plane_damage - Iterator macro for plane damage. @iter: The iterator to advance. @rect: Return a rectangle in fb coordinate clipped to plane src.

Note that if the first call to iterator macro return false then no need to do plane update. Iterator will return full plane src when damage is not passed by user-space.
