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