OPTIONS

12       --debug
13           Setup debug variable (see list below) in value range (0, 10). Use

DESCRIPTION

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