The bulk of the MPAM driver lives outside the arch code because it largely manages MMIO devices that generate interrupts. The driver needs a Kconfig symbol to enable it. As MPAM is only found on arm64 platforms, the arm64 tree is the most natural home for the Kconfig option. This Kconfig option will later be used by the arch code to enable or disable the MPAM context-switch code, and to register properties of CPUs with the MPAM driver.

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 reStructuredText 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.
