This code is ported from the DRM git tree and allows the vblank interrupts to function on the i965 hw. It also requires a change in Mesa's 965 driver to actually use them. [ Without this patch, my 965GM drops vblank interrupts - Jesse ] Signed-off-by: Dave Airlie <airlied@linux.ie> Acked-by: Jesse Barnes <jesse.barnes@intel.com> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
