intelfb: add vsync interrupt support
[04/05] intelfb: implement FBIO_WAITFORVSYNC ioctl The (unofficial) FBIO_WAITFORVSYNC ioctl is implemented by sleeping on the appropriate waitqueue, as defined in my earlier patch. Currently, only display 0 (aka pipe A) is supported. Signed-off-by: Eric Hustvedt <ehustvedt@cecropia.com>
