CONFIG_INT_LATENCY_BENCHMARK:

This option enables the tracking of interrupt latency metrics; the exact set of metrics being tracked is board-dependent. Tracking begins when int_latency_init() is invoked by an application. The metrics are displayed (and a new sampling interval is started) each time int_latency_show() is called thereafter.
