drm/i915: include hangcheck action and score in error_state
Score and action reveals what all the rings were doing and why hang was declared. Add idle state so that we can distinguish between waiting and idle ring. v2: - add idle as a hangcheck action - consensed hangcheck status to single line (Chris) - mark active explicitly when we are making progress (Chris) Reviewed-by: Chris Wilson <chris@chris-wilson.co.uk> Signed-off-by: Mika Kuoppala <mika.kuoppala@intel.com> Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch>
