DG2 has issues. To work around one of these the GuC must schedule apps in an exclusive manner across both RCS and CCS. That is, if a context from app X is running on RCS then all CCS engines must sit idle even if there are contexts from apps Y, Z, ... waiting to run. A certain OS favours RCS to the total starvation of CCS. Linux does not. Hence the GuC now has a scheduling policy setting to control this abitration.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
