rtla timerlat [MODE] ...
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 provides information for each noise via the osnoise: tracepoints. The rtla timerlat top mode displays a summary of the periodic output from the timerlat tracer. The rtla hist hist mode displays a histogram of each tracer event occurrence. For further details, please refer to the respective man page.
