40 * FB_DAMAGE_CLIPS is an optional plane property which provides a means to
41 * specify a list of damage rectangles on a plane in framebuffer coordinates of
42 * the framebuffer attached to the plane. In current context damage is the area
43 * of plane framebuffer that has changed since last plane update (also called
45 * framebuffer attached during last plane update or not.
52 * ignore damage clips property and in that case driver will do a full plane
54 * inside damage clips will be updated to plane. For efficiency driver can do
59 * framebuffer (since last plane update) can result in incorrect rendering.
62 * array of &drm_mode_rect. Unlike plane &drm_plane_state.src coordinates,
63 * damage clips are not in 16.16 fixed point. Similar to plane src in

91 * drm_plane_enable_fb_damage_clips - Enables plane fb damage clips property.
92 * @plane: Plane on which to enable damage clips property.
94 * This function lets driver to enable the damage clips property on a plane.
