Lines Matching full:shadow

20  * for planes with shadow buffers.
47  * A driver using a shadow buffer copies the content of the shadow buffers
49  * a mapping of the shadow buffer into kernel address space. The mappings
53  * The helpers for shadow-buffered planes establish and release mappings,
57  * Shadow-buffered planes can easily be enabled by using the provided macros
60  * shadow-buffer helpers.
76  * In the driver's atomic-update function, shadow-buffer mappings are available
89  *		// access shadow buffer via shadow_plane_state->map
98  * callbacks. Access to shadow-buffer mappings is similar to regular
115  *		// access shadow buffer via shadow_plane_state->map
182  * Shadow-buffered Planes
186  * __drm_gem_duplicate_shadow_plane_state - duplicates shadow-buffered plane state
188  * @new_shadow_plane_state: the new shadow-buffered plane state
190  * This function duplicates shadow-buffered plane state. This is helpful for drivers
193  * The function does not duplicate existing mappings of the shadow buffers.
207  * drm_gem_duplicate_shadow_plane_state - duplicates shadow-buffered plane state
211  * shadow-buffered planes. It assumes the existing state to be of type
215  * The function does not duplicate existing mappings of the shadow buffers.
242  * __drm_gem_destroy_shadow_plane_state - cleans up shadow-buffered plane state
243  * @shadow_plane_state: the shadow-buffered plane state
245  * This function cleans up shadow-buffered plane state. Helpful for drivers that
255  * drm_gem_destroy_shadow_plane_state - deletes shadow-buffered plane state
260  * for shadow-buffered planes. It expects that mappings of shadow buffers
275  * __drm_gem_reset_shadow_plane - resets a shadow-buffered plane
277  * @shadow_plane_state: the shadow-buffered plane state
279  * This function resets state for shadow-buffered planes. Helpful
290  * drm_gem_reset_shadow_plane - resets a shadow-buffered plane
294  * shadow-buffered planes. It assumes the current plane state to be
315  * drm_gem_prepare_shadow_fb - prepares shadow framebuffers
347  * drm_gem_cleanup_shadow_fb - releases shadow framebuffers
369  * drm_gem_simple_kms_prepare_shadow_fb - prepares shadow framebuffers
391  * drm_gem_simple_kms_cleanup_shadow_fb - releases shadow framebuffers
408  * drm_gem_simple_kms_reset_shadow_plane - resets a shadow-buffered plane
412  * for shadow-buffered planes.
421  * drm_gem_simple_kms_duplicate_shadow_plane_state - duplicates shadow-buffered plane state
425  * for shadow-buffered planes. It does not duplicate existing mappings of the shadow
440  * drm_gem_simple_kms_destroy_shadow_plane_state - resets shadow-buffered plane state
445  * for shadow-buffered planes. It expects that mappings of shadow buffers
