MCR registers can be placed on the GuC's save/restore list, but at the moment they are always handled in a multicast manner (i.e., the GuC reads one instance to save the value and then does a multicast write to restore that single value to all instances). In the future the GuC will probably give us an alternate interface to do unicast per-instance save/restore operations, so we should be very clear about which registers on the list are MCR registers (and in the future which save/restore behavior we want for them).

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.
