CHA merges the caching agent and Home Agent (HA) responsibilities of the chip into a single block. It's one of the Sapphire Rapids server uncore units. The layout of the control registers for a CHA uncore unit is a little bit different from the generic one. The CHA uncore unit also supports a filter register for TID. So a specific format and ops are required. Expose the common MSR ops which can be reused.

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.
