ftrace: add trace-cmd for ftrace control and config
Rather than manually configuring ftrace, trace-cmd was created to provide a more user friendly interface to the tracer. Some examples are: # ./trace-cmd record -e all ls /bin Then to see the information: # ./trace-cmd report To see just a subsystem: # ./trace-cmd record -e irq ls /bin To list the available trace events: # ./trace-cmd list -e You can also trace a single trace point with one of two methods: # ./trace-cmd record -e sched:sched_wakeup ls /bin Or simply: # ./trace-cmd record -e sched_wakeup ls /bin This tool also works with tracers (plugins) as well as events # ./trace-cmd list -p Signed-off-by: Bruce Ashfield <bruce.ashfield@windriver.com>
