Subject:   Way to run a routine on different cpu

Hi,

I am wondering what is the right way to run a routine on a differnet cpu and wait for it to complete in FreeBSD kernel. For example, on cpu-0 I want to send a IPI to cpu-1 to let it run a routine called foo(). On cpu-0 I will wait till foo() completes. Is smp_rendezvous() the right way to do it? What if I only want it to run on one cpu, not all cpus?

Thanks,
Wei
