Historically we've initialized all undefined/reserved entries in a platform's MOCS table to the contents of table entry #1 (i.e., I915_MOCS_PTE). Going forward, we can't assume that table entry #1 will always contain suitable values to use for undefined/reserved table indices. We'll allow a platform-specific table index to be selected at table initialization time in these cases. This new mechanism to select L3 WB entry will be applicable for all the Gen12+ platforms except TGL and RKL. Since TGL and RLK are already in production so their mocs settings are intact to avoid ABI break.

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.
