Public bug reported:

from https://01.org/linuxgraphics/downloads/2015/gen9-intel-graphics-
firmwares-linux-guc-ver1-dcm-ver4

Description

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

GuC

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.

Version: 1.00
Date   : 1/19/2015
Notes:
1. Baseline release
2. Support for KMD and direct submissions
3. Support for S3/S4 & Device Reset

DCM

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.

Version: 4.00
Date   : 3/30/2015
Notes:
Following additions from ver3.0
1. Fixed Headers byte length

** Affects: linux-firmware (Ubuntu)
     Importance: High
         Status: New

** Changed in: linux-firmware (Ubuntu)
   Importance: Undecided => High
