DESCRIPTION

33       Performance counters for Linux are a new kernel-based subsystem that
34       provide a framework for all things performance analysis. It covers
35       hardware level (CPU/PMU, Performance Monitoring Unit) features and
36       software features (software counters, tracepoints) as well.
