MBM (Memory Bandwidth Monitoring) test is the first implemented selftest. It starts a stressful memory bandwidth benchmark and assigns the bandwidth pid in a resctrl monitoring group. Read and compare perf IMC counter and MBM total bytes for the benchmark. The numbers should be close enough to pass the test. Default benchmark is built-in fill_buf. But users can specify their own benchmark by option "-b". We can add memory bandwidth monitoring for multiple processes in the future.

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.
