0001 The **rtla timerlat** tool is an interface for the *timerlat* tracer. The
0002 *timerlat* tracer dispatches a kernel thread per-cpu. These threads
0003 set a periodic timer to wake themselves up and go back to sleep. After
0004 the wakeup, they collect and generate useful information for the
0005 debugging of operating system timer latency.
0006
0007 The *timerlat* tracer outputs information in two ways. It periodically
0008 prints the timer latency at the timer *IRQ* handler and the *Thread*
0009 handler. It also enable the trace of the most relevant information via
0010 **osnoise:** tracepoints.
