      drm/todo: Add entry for moving to dma_resv_lock · 5823cca3
      Daniel Vetter authored
      Requested by Thomas. I think it justifies a new level, since I tried
      to make some forward progress on this last summer, and gave up (for
      now). This is very tricky.

      drm/scheduler: Job timeout handler returns status (v3) · a6a1f036
      Luben Tuikov authored
      This patch does not change current behaviour.
      
      The driver's job timeout handler now returns
      status indicating back to the DRM layer whether
      the device (GPU) is no longer available, such as
      after it's been unplugged, or whether all is
      normal, i.e. current behaviour.
      
      All drivers which make use of the
      drm_sched_backend_ops' .timedout_job() callback
      have been accordingly renamed and return the
      would've-been default value of
      DRM_GPU_SCHED_STAT_NOMINAL to restart the task's
      timeout timer--this is the old behaviour, and is
      preserved by this patch.
      
      v2: Use enum as the status of a driver's job
          timeout callback method.
      
      v3: Return scheduler/device information, rather
          than task information.
