ACPI 6.4 adds a 'cache id' to the PPTT Cache Type Structure. Copy this property across into the cacheinfo leaf when it was provided by firmware. This value gets exposed to userspace as: /sys/devices/system/cpu/cpu*/cache/index*/id. See the "Cache IDs" section of Documentation/x86/resctrl.rst.

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.
