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