Dan Eischen and Julian Elischer,
I'd really like the ability to pin to a processor. However, I
think I need something stronger than immediately rescheduling the
current process as seems to be done in the 4bsd scheduler. I'd like
to own the cpu as much as possible until the pinned thread
What you are trying to do is real-time work. You will need
to place your thread(s) or process in the real-time class
or priority range and modify the scheduler(s) if necessary
to support RT. I'm not familiar with the schedulers, but
I suspect most of your work should be spent on getting
one of

Yes, it needed byte reversal or something. That would indeed be

Previously when I asked this question it turned out to not be as
necessary as I thought. However, I now need a way to pin/bind a
user-space thread to a processor until I'm done with it as my
timing constraints are too tight to account for.
I checked sys/sched.h, sys/proc.h, pthread.h, and
6 matches
