Is there a way to make the current thread yield the processor in a kext?

I understand that by default threads executing in the kernel are
pre-emptable, but sometimes I would like the current thread to
explicitly give the scheduler a chance to schedule another thread,
before the current thread's timeslice has elapsed. I'm looking for
something similar to cond_resched() on Linux.

As you probably know, there's the I/O Kit world with its way of doing things, then there's the rest of the kernel. Which are you asking about?

What's going on in your kext when you want to yield?

Thanks,
