DESCRIPTION

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