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."
