Extra info and code examples

A miscellaneous collection of in-development and unsupported performance analysis tools for Linux perf_events, aka the "perf" command, and ftrace. Both perf_events and ftrace are core Linux tracing tools, and are included in the Linux kernel source. These tools are designed to be simple to use, easy to install, and provide advanced performance observability. This collection was written by Brendan Gregg (author of the DTraceToolkit). Many of these tools employ workarounds so that functionality is possible on existing Linux kernels. Because of this, many tools have caveats (see man pages), and their implementation should be considered a placeholder until future kernel features, or new tracing subsystems, are added.
