+/*
+ * Mark a region of a framebuffer as dirty.
+ *
+ * Some hardware does not automatically update display contents
+ * as a hardware or software draw to a framebuffer. This ioctl
+ * allows userspace to tell the kernel and the hardware what
+ * regions of the framebuffer have changed.
+ *
+ * The kernel or hardware is free to update more then just the
+ * region specified by the clip rects. The kernel or hardware
+ * may also delay and/or coalesce several calls to dirty into a
+ * single update.
+ *
+ * Userspace may annotate the updates, the annotates are a
+ * promise made by the caller that the change is either a copy
+ * of pixels or a fill of a single color in the region specified.
+ *
+ * If the DRM_MODE_FB_DIRTY_ANNOTATE_COPY flag is given then
+ * the number of updated regions are half of num_clips given,
+ * where the clip rects are paired in src and dst. The width and
+ * height of each one of the pairs must match.
+ *
+ * If the DRM_MODE_FB_DIRTY_ANNOTATE_FILL flag is given the caller
+ * promises that the region specified of the clip rects is filled
+ * completely with a single color as given in the color argument.
