      drm/i915/dp: Fix DP MST error after unplugging TypeC cable · 99785b86
      Srinivasan S authored
      This patch avoids DP MST payload error message in dmesg, as it is trying
      to update the payload to the disconnected DP MST device. After DP MST
      device is disconnected we should not be updating the payload and
      hence remove the error.
      
      v2: Removed the connector status check and converted from error to debug.

      drm/i915: Initialise breadcrumb lists on the virtual engine · f8db4d05
      Chris Wilson authored
      With deferring the breadcrumb signalling to the virtual engine (thanks
      preempt-to-busy) we need to make sure the lists and irq-worker are ready
      to send a signal.
