agent (HA), to name a few. Most of these components provide similar performance monitoring
capabilities.

Uncore PMON Overview

The uncore performance monitoring facilities are organized into per-component performance
monitoring (or 'PMON') units. A PMON unit within an uncore component may contain one of more
sets of counter registers. With the exception of the UBox, each PMON unit provides a unit-level
control register to synchronize actions across the counters within the box (e.g., to start/stop
counting).
