1The **rtla timerlat** tool is an interface for the *timerlat* tracer. The
2*timerlat* tracer dispatches a kernel thread per-cpu. These threads
3set a periodic timer to wake themselves up and go back to sleep. After
4the wakeup, they collect and generate useful information for the
5debugging of operating system timer latency.

7The *timerlat* tracer outputs information in two ways. It periodically
8prints the timer latency at the timer *IRQ* handler and the *Thread*
9handler. It also enable the trace of the most relevant information via
10**osnoise:** tracepoints.
