The Arm NI-700 Network-on-Chip Interconnect has a relatively straightforward design with a hierarchy of voltage, power, and clock domains, where each clock domain then contains a number of interface units and a PMU which can monitor events thereon. As such, it begets a relatively straightforward driver to interface those PMUs with perf. Even more so than with arm-cmn, users will require detailed knowledge of the wider system topology in order to meaningfully analyse anything, since the interconnect itself cannot know what lies beyond the boundary of each inscrutably-numbered interface. Given that, for now they are also expected to refer to the NI-700 documentation for the relevant event IDs to provide as well. An identifier is implemented so we can come back and add jevents if anyone really wants to.

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.
