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
