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.
