      drm/i915: Tighting frontbuffer tracking around flips · 11c9b6c6
      Daniel Vetter authored
      So I think I've spotted a small gap in the frontbuffer tracking
      while discussing the logic with Paulo on irc:
      
      1. Userspace schedules gpu rendering to the current frontbuffer.
      This gets tracked in dev_priv->fb_tracking.busy_bits.
      
      2. We pageflip a fully rendered buffer before the frontbuffer
      rendering completes.
      
      3. The request retiring will never clear busy_bits (since at retire
      time the old frontbuffer won't have obj->frontbuffer_bits set), so
      these bits now are stuck until someone again does a bit of frontbuffer
      tracking.
      
      If we clear stale busy_bits in flip_prepare this gap is closed.
