perf: performance analysis tools for Linux
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.
To enforce the coupling between userspace and kernel, this
commit introduces perf as a subpackage of the linux-wrs tree.
perf is built directly inside the kernel tree (and hence picks
up all appropriate patches), but is packaged as a separate
utility that can be added to the rootfs and used to analyze
the kernel.
