software event latency or duration

Hi all,

I'm wandering how to use perf tool to get the event latency of SW event. just like the commond "perf sched latency" does, shows the time cost by the context-switch. Is there some commond like that i can measure the interrupt latency, or pagefault latency? Is it possible to show all the individual event's time cost?
Any reply is much appreciated!

Best,
Chen
