Bug description:
from https://01.org/linuxgraphics/intel-linux-graphics-firmwares
Description
Gen9 Intel® Graphics for Linux (Skylake) includes 2 microcontrollers
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.
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.
