235 * Mark a region of a framebuffer as dirty.
236 *
237 * Some hardware does not automatically update display contents
238 * as a hardware or software draw to a framebuffer. This ioctl
239 * allows userspace to tell the kernel and the hardware what
240 * regions of the framebuffer have changed.
241 *
242 * The kernel or hardware is free to update more then just the
243 * region specified by the clip rects. The kernel or hardware
244 * may also delay and/or coalesce several calls to dirty into a
245 * single update.
246 *
247 * Userspace may annotate the updates, the annotates are a
248 * promise made by the caller that the change is either a copy
249 * of pixels or a fill of a single color in the region specified.
250 *
251 * If the DRM_MODE_FB_DIRTY_ANNOTATE_COPY flag is given then
252 * the number of updated regions are half of num_clips given,
253 * where the clip rects are paired in src and dst. The width and
254 * height of each one of the pairs must match.
255 *
256 * If the DRM_MODE_FB_DIRTY_ANNOTATE_FILL flag is given the caller
257 * promises that the region specified of the clip rects is filled
258 * completely with a single color as given in the color argument.

316 * Request a page flip on the specified crtc.

318 * This ioctl will ask KMS to schedule a page flip for the specified
319 * crtc. Once any pending rendering targeting the specified fb (as of
320 * ioctl time) has completed, the crtc will be reprogrammed to display
321 * that fb after the next vertical refresh. The ioctl returns
322 * immediately, but subsequent rendering to the current fb will block
323 * in the execbuffer ioctl until the page flip happens. If a page
324 * flip is already pending as the ioctl is called, EBUSY will be
325 * returned.
326 *
327 * The ioctl supports one flag, DRM_MODE_PAGE_FLIP_EVENT, which will
328 * request that drm sends back a vblank event (see drm.h: struct
329 * drm_event_vblank) when the page flip is done. The user_data field
330 * passed in with this ioctl will be returned as the user_data field
331 * in the vblank event struct.

334 * clever to use it for.
