Cache and memory bandwidth monitoring are features that are part of x86 CPU resource control that is supported by the resctrl subsystem. The monitoring properties are obtained via CPUID from every CPU and only used within the resctrl subsystem where the properties are only read from boot_cpu_data. Obtain the monitoring properties once, placed in boot_cpu_data, via the ->c_bsp_init() helpers of the vendors that support X86_FEATURE_CQM_LLC.

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.
