%description
This package provides a userspace tool 'perf', which monitors performance for
either unmodified binaries or the entire system. It requires a Linux kernel
which includes the Performance Counters for Linux (PCL) subsystem (>= 2.6.31).
This subsystem utilizes the Performance Monitoring Unit (PMU) / hardware
counters of the underlying cpu architecture (if supported).
