0067 DESCRIPTION
0068 -----------
0069 Performance counters for Linux are a new kernel-based subsystem
0070 that provide a framework for all things performance analysis. It
0071 covers hardware level (CPU/PMU, Performance Monitoring Unit) features
0072 and software features (software counters, tracepoints) as well.
