3  * drm gem framebuffer helper functions
44  * drm_gem_fb_get_obj() - Get GEM object backing the framebuffer
45  * @fb: Framebuffer
52  * Pointer to &drm_gem_object for the given framebuffer and plane index or NULL
87 		drm_err(dev, "Failed to init framebuffer: %d\n", ret);  in drm_gem_fb_init()
93  * drm_gem_fb_destroy - Free GEM backed framebuffer
94  * @fb: Framebuffer
96  * Frees a GEM backed framebuffer with its backing buffer(s) and the structure
113  * drm_gem_fb_create_handle - Create handle for GEM backed framebuffer
114  * @fb: Framebuffer
118  * This function creates a handle for the GEM object backing the framebuffer.
139  * @fb: framebuffer object
140  * @file: DRM file that holds the GEM handle(s) backing the framebuffer
142  * @mode_cmd: Metadata from the userspace framebuffer creation request
143  * @funcs: vtable to be used for the new framebuffer object
146  * custom framebuffer callbacks. Use drm_gem_fb_create() if you don't need to
220  * @file: DRM file that holds the GEM handle(s) backing the framebuffer
222  * @mode_cmd: Metadata from the userspace framebuffer creation request
223  * @funcs: vtable to be used for the new framebuffer object
226  * custom framebuffer callbacks. Use drm_gem_fb_create() if you don't need to
264  * @file: DRM file that holds the GEM handle(s) backing the framebuffer
266  * @mode_cmd: Metadata from the userspace framebuffer creation request
268  * This function creates a new framebuffer object described by
270  * backing the framebuffer.
274  * validation. Use drm_gem_fb_create_with_dirty() if you need framebuffer
303  * @file: DRM file that holds the GEM handle(s) backing the framebuffer
305  * @mode_cmd: Metadata from the userspace framebuffer creation request
307  * This function creates a new framebuffer object described by
309  * backing the framebuffer. drm_atomic_helper_dirtyfb() is used for the dirty
310  * callback giving framebuffer flushing through the atomic machinery. Use
334  * drm_gem_fb_vmap - maps all framebuffer BOs into kernel address space
335  * @fb: the framebuffer
339  * This function maps all buffer objects of the given framebuffer into
346  * is different from @map if the framebuffer's offsets field is non-zero.
398  * drm_gem_fb_vunmap - unmaps framebuffer BOs from kernel address space
399  * @fb: the framebuffer
402  * This function unmaps all buffer objects of the given framebuffer.
447  * @fb: the framebuffer
450  * Prepares a framebuffer's GEM buffer objects for CPU access. This function
490  * @fb: the framebuffer
493  * Signals the end of CPU access to the given framebuffer's GEM buffer objects. This
586  * @afbc_fb: afbc-specific framebuffer
588  * @mode_cmd: Metadata from the userspace framebuffer creation request
589  * @afbc_fb: afbc framebuffer
