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.
