Ville Syrjälä 5e2032d47a drm/i915: Eliminate race from gen2/3 page flip interrupt handling ... If the interrupt handler were to process a previous vblank interrupt and the following flip pending interrupt at the same time, the page flip would be completed too soon. To eliminate this race, check the live pending flip status from the ISR register before finishing the page flip. v2: Added a comment explaining the logic (by Chris Wilson) v3: Fix a typo in the comment Reviewed-by: Chris Wilson <chris@chris-wilson.co.uk> Tested-by: Chris Wilson <chris@chris-wilson.co.uk> Signed-off-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch>		2013-02-20 15:03:05 +01:00
