Bug description:
  from https://01.org/linuxgraphics/intel-linux-graphics-firmwares


  Gen9 Intel® Graphics for Linux (Skylake) includes 2 microcontrollers
  to extract maximum performance and to provide low power states for
  better power consumption.


  GuC is an embedded micro-controller in the graphics sub-system that is
  designed to perform graphics workload scheduling on the various
  graphics parallel engines. In this scheduling model, host software
  submits work through one of the 256 graphics doorbells and this
  invokes the micro-kernel running on the GuC core to perform the
  scheduling operation on the appropriate graphics engine. Scheduling
  operations include determining which workload to run next, submitting
  a workload to a command streamer, pre-empting existing workloads
  running on an engine, monitoring progress and notifying host SW when
  work is done.


  DCM is a display micro-controller that provides additional low-power
  idle states for improved platform power consumption.  The
  skl_dmc_ver4.bin firmware is hot-loaded to the display microcontroller
  at runtime, and the microcontroller manages the additional low-power
  idle states independently from the OS/Kernel.
