drm/i915: announce to userspace that the bsd ring is coherent
Otherwise we can't really fix the abi-braindeadness of forcing libva to manually wait for rendering when switching rings. Which in turn makes implementing hw semaphores a pointless exercise (at least for ironlake). [Also added the relaxed fencing param to explain the jump in numbering - relaxed fencing is in -next.] Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch> Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>
