SUMMARY = "Performance analysis tools for Linux" 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."
