sys/sys : evcount.h
Log message:
Add support for per-cpu event counters, to be used for clock and IPI
counters where the event being counted occurs across all CPUs in the
system. Counter instances can be made per-cpu by calling evcount_percpu()
after the counter is attached, and this can occur before or after all system
CPUs are attached. Per-cpu counter instances should be incremented using
evcount_inc().
