DESCRIPTION

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