716 	 * get_vblank_counter - get raw hardware vblank counter
720 	 * Driver callback for fetching a raw hardware vblank counter for @crtc.
723 	 * missed vblank events while interrupts where disabled based on system
730 	 * Raw vblank counter value.
735 	 * enable_vblank - enable vblank interrupt events
739 	 * Enable vblank interrupts for @crtc.  If the device doesn't have
740 	 * a hardware vblank counter, this routine should be a no-op, since
744 	 * Zero on success, appropriate errno if the given @crtc's vblank
750 	 * disable_vblank - disable vblank interrupt events
754 	 * Disable vblank interrupts for @crtc.  If the device doesn't have
755 	 * a hardware vblank counter, this routine should be a no-op, since
774 	 * Called by vblank timestamping code.
784 	 * Returns vpos as a negative number inside vblank, counting the number
785 	 * of scanlines to go until end of vblank, e.g., -1 means "one scanline
786 	 * until start of active scanout / end of vblank."
791 	 * DRM_SCANOUTPOS_INVBL = Inside vblank.
802 	 * timestamp when the most recent VBLANK interval ended or will end.
806 	 * the video frame after the end of VBLANK will start scanning out,
807 	 * the time immediately after end of the VBLANK interval. If the
808 	 * @crtc is currently inside VBLANK, this will be a time in the future.
