What is ftrace?
Ftrace is an internal tracer designed to find what is going on inside the kernel.
It can be used for debugging or analyzing latencies and performance issues that take place outside of user-space.
Although ftrace is typically considered the function tracer, it is really a frame work of several assorted tracing utilities.
There's latency tracing to examine what occurs between interrupts disabled and enabled, as well as for preemption and from a time a task is woken to the task is actually scheduled in.
One of the most common uses of ftrace is the event tracing. Through out the kernel is hundreds of static event points that can be enabled via the debugfs file system to see what is going on in certain parts of the kernel.
