Lines Matching full:shadow

22  * for planes with shadow buffers.
41  * A driver using a shadow buffer copies the content of the shadow buffers
43  * a mapping of the shadow buffer into kernel address space. The mappings
47  * The helpers for shadow-buffered planes establish and release mappings,
51  * Shadow-buffered planes can easily be enabled by using the provided macros
54  * shadow-buffer helpers.
70  * In the driver's atomic-update function, shadow-buffer mappings are available
83  *		// access shadow buffer via shadow_plane_state->map
92  * callbacks. Access to shadow-buffer mappings is similar to regular
109  *		// access shadow buffer via shadow_plane_state->map
201  * Shadow-buffered Planes
205  * __drm_gem_duplicate_shadow_plane_state - duplicates shadow-buffered plane state
207  * @new_shadow_plane_state: the new shadow-buffered plane state
209  * This function duplicates shadow-buffered plane state. This is helpful for drivers
212  * The function does not duplicate existing mappings of the shadow buffers.
226  * drm_gem_duplicate_shadow_plane_state - duplicates shadow-buffered plane state
230  * shadow-buffered planes. It assumes the existing state to be of type
234  * The function does not duplicate existing mappings of the shadow buffers.
261  * __drm_gem_destroy_shadow_plane_state - cleans up shadow-buffered plane state
262  * @shadow_plane_state: the shadow-buffered plane state
264  * This function cleans up shadow-buffered plane state. Helpful for drivers that
274  * drm_gem_destroy_shadow_plane_state - deletes shadow-buffered plane state
279  * for shadow-buffered planes. It expects that mappings of shadow buffers
294  * __drm_gem_reset_shadow_plane - resets a shadow-buffered plane
296  * @shadow_plane_state: the shadow-buffered plane state
298  * This function resets state for shadow-buffered planes. Helpful
309  * drm_gem_reset_shadow_plane - resets a shadow-buffered plane
313  * shadow-buffered planes. It assumes the current plane state to be
334  * drm_gem_begin_shadow_fb_access - prepares shadow framebuffers for CPU access
361  * drm_gem_end_shadow_fb_access - releases shadow framebuffers from CPU access
383  * drm_gem_simple_kms_begin_shadow_fb_access - prepares shadow framebuffers for CPU access
403  * drm_gem_simple_kms_end_shadow_fb_access - releases shadow framebuffers from CPU access
421  * drm_gem_simple_kms_reset_shadow_plane - resets a shadow-buffered plane
425  * for shadow-buffered planes.
434  * drm_gem_simple_kms_duplicate_shadow_plane_state - duplicates shadow-buffered plane state
438  * for shadow-buffered planes. It does not duplicate existing mappings of the shadow
453  * drm_gem_simple_kms_destroy_shadow_plane_state - resets shadow-buffered plane state
458  * for shadow-buffered planes. It expects that mappings of shadow buffers
