Performance Monitoring Unit Guidelines

by Peggy Irelan and Shihjong Kuo

In order to facilitate simpler development and maintenance of performance monitoring tools, Intel has begun the transition to create an architecturally-defined approach for software agents to interacting with the PMU. This approach is known as "architectural Performance Monitoring (PerfMon)," as opposed to the traditional "model-specific Performance Monitoring (PerfMon)." The purpose of architectural PerfMon is to provide a functionally and logically consistent set of capabilities with a consistent hardware interface that developers can rely on now and in the future.
