| 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. |
