Intel Memory Bandwidth Monitoring (MBM) counters may report system memory bandwidth incorrectly on some Intel processors. This is reported in documented in erratum SKX99, erratum BDF102 and in the RDT reference manual, see Documentation/x86/index.rst. To work around the errata, MBM total and local readings are corrected using a correction factor table. Since the correction factor table is not publicly documented anywhere, document the table and the errata in Documentation/x86/resctrl.rst for future reference.

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.
