Hi,

I am wondering what is the right way to run a routine on a differnet cpu an=
d wait for it to complete in FreeBSD kernel. For example, on cpu-0 I want t=
o 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? Wha=
t if I only want it to run on one cpu, not all cpus?

Thanks,
Wei
