Mika Kuoppala f72b3435c1 drm/i915: Don't emit semaphore wait if wrap happened ... If wrap just happened we need to prevent emitting waits for pre wrap values. Detect this and emit no-ops instead. v2: Use olr > seqno to detect wrap instead of *seqno == 0 as suggested by Chris Wilson. v3: Use last used seqno to detect the wraparound. From Chris Wilson v4: Fixed unnecessary last_seqno assigment References: https://bugs.freedesktop.org/show_bug.cgi?id=57967 Signed-off-by: Mika Kuoppala <mika.kuoppala@intel.com> Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch>		2012-12-11 13:32:26 +01:00
