Lines Matching defs:damage
46  * specify a list of damage rectangles on a plane in framebuffer coordinates of
47  * the framebuffer attached to the plane. In current context damage is the area
57  * ignore damage clips property and in that case driver will do a full plane
58  * update. In case damage clips are provided then it is guaranteed that the area
59  * inside damage clips will be updated to plane. For efficiency driver can do
60  * full update or can update more than specified in damage clips. Since driver
63  * provides damage clips which doesn't encompass the actual damage to
68  * damage clips are not in 16.16 fixed point. Similar to plane src in
69  * framebuffer, damage clips cannot be negative. In damage clip, x1/y1 are
71  * damage clips, it is strongly discouraged.
73  * Drivers that are interested in damage interface for plane should enable
75  * Drivers implementing damage can use drm_atomic_helper_damage_iter_init() and
76  * drm_atomic_helper_damage_iter_next() helper iterator function to get damage
96  * drm_plane_enable_fb_damage_clips - Enables plane fb damage clips property.
97  * @plane: Plane on which to enable damage clips property.
99  * This function lets driver to enable the damage clips property on a plane.
112  * drm_atomic_helper_check_plane_damage - Verify plane damage on atomic_check.
114  * @plane_state: Plane state for which to verify damage.
116  * This helper function makes sure that damage from plane state is discarded
118  * plane update rather than processing individual damage regions, then those
123  * &drm_plane_state.src as damage.
154  * A helper to implement &drm_framebuffer_funcs.dirty using damage interface

263  * drm_atomic_helper_damage_iter_init - Initialize the damage iterator.
266  * @state: Plane state from which to iterate the damage clips.
268  * Initialize an iterator, which clips plane damage
270  * returns full plane src in case damage is not present because either
273  * changed but that can be changed in future to return damage.
308  * drm_atomic_helper_damage_iter_next - Advance the damage iterator.
312  * Since plane src is in 16.16 fixed point and damage clips are whole number,
315  * off for full plane src, in case it's returned as damage. This iterator will
316  * skip damage clips outside of plane src.
350  * drm_atomic_helper_damage_merged - Merged plane damage
352  * @state: Plane state from which to iterate the damage clips.
353  * @rect: Returns the merged damage rectangle
355  * This function merges any valid plane damage clips into one rectangle and
362  * True if there is valid plane damage otherwise false.
