[ Upstream commit c828441f21ddc819a28b5723a72e3c840e9de1c6 ] The uncore subsystem for Meteor Lake is similar to the previous Alder Lake. The main difference is that MTL provides PMU support for different tiles, while ADL only provides PMU support for the whole package. On ADL, there are CBOX, ARB, and clockbox uncore PMON units. On MTL, they are split into CBOX/HAC_CBOX, ARB/HAC_ARB, and cncu/sncu which provides a fixed counter for clockticks. Also, new MSR addresses are introduced on MTL. The IMC uncore PMON is the same as Alder Lake. Add new PCIIDs of IMC for Meteor Lake.

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.
