Matt Roper 564e1a82fb drm/xe/pat: Determine ATS / PTA programming during early sw init
Decide whether programming of the special ATS and PTA PAT entries is
necessary (and which entries should be programmed) during early software
initialization rather than hardcoding this into the 'program' functions.
Future platforms may want to re-use the same functions but utilize
different special entry values.  Consolidating all of the decisions
into one place keeps things simple.

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 reStructuredText 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.
