3  * drm gem framebuffer helper functions
43  * drm_gem_fb_get_obj() - Get GEM object backing the framebuffer
44  * @fb: Framebuffer
51  * Pointer to &drm_gem_object for the given framebuffer and plane index or NULL
80 		drm_err(dev, "Failed to init framebuffer: %d\n", ret);  in drm_gem_fb_init()
86  * drm_gem_fb_destroy - Free GEM backed framebuffer
87  * @fb: Framebuffer
89  * Frees a GEM backed framebuffer with its backing buffer(s) and the structure
106  * drm_gem_fb_create_handle - Create handle for GEM backed framebuffer
107  * @fb: Framebuffer
111  * This function creates a handle for the GEM object backing the framebuffer.
132  * @fb: framebuffer object
133  * @file: DRM file that holds the GEM handle(s) backing the framebuffer
134  * @mode_cmd: Metadata from the userspace framebuffer creation request
135  * @funcs: vtable to be used for the new framebuffer object
138  * custom framebuffer callbacks. Use drm_gem_fb_create() if you don't need to
203  * @file: DRM file that holds the GEM handle(s) backing the framebuffer
204  * @mode_cmd: Metadata from the userspace framebuffer creation request
205  * @funcs: vtable to be used for the new framebuffer object
208  * custom framebuffer callbacks. Use drm_gem_fb_create() if you don't need to
245  * @file: DRM file that holds the GEM handle(s) backing the framebuffer
246  * @mode_cmd: Metadata from the userspace framebuffer creation request
248  * This function creates a new framebuffer object described by
250  * backing the framebuffer.
254  * validation. Use drm_gem_fb_create_with_dirty() if you need framebuffer
282  * @file: DRM file that holds the GEM handle(s) backing the framebuffer
283  * @mode_cmd: Metadata from the userspace framebuffer creation request
285  * This function creates a new framebuffer object described by
287  * backing the framebuffer. drm_atomic_helper_dirtyfb() is used for the dirty
288  * callback giving framebuffer flushing through the atomic machinery. Use
399  * @afbc_fb: afbc-specific framebuffer
400  * @mode_cmd: Metadata from the userspace framebuffer creation request
401  * @afbc_fb: afbc framebuffer
437  * drm_gem_fb_prepare_fb() - Prepare a GEM backed framebuffer
448  * gem based framebuffer drivers which have their buffers always pinned in
