      drm/i915: Wait for pending flips on the GPU · e59f2bac
      Chris Wilson authored
      Currently, if a batch buffer refers to an object with a pending flip,
      then we sleep until that pending flip is completed (unpinned and
      signalled). This is so that a flip can be queued and the user can
      continue rendering to the backbuffer oblivious to whether the buffer is
      still pinned as the scan out. (The kernel arbitrating at the last moment
      to stall the batch and wait until the buffer is unpinned and replaced as
      the front buffer.)
      
      As we only have a queue depth of 1, we can simply wait for the current
      pending flip to complete and continue rendering. We can achieve this
      with a single WAIT_FOR_EVENT command inserted into the ring buffer prior
      to executing the batch, *without* stalling the client.

      drm/i915: Free hardware status page on unload when physically mapped · c2873e96
      Keith Packard authored
      A physically mapped hardware status page is allocated at driver load
      time but was never freed. Call the existing code to free this page at
      driver unload time on hardware which uses this kind.
