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. |
