| 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." |
