I've looked around a bit, but haven't seen this. Is there a "magic switch" that I can flip to disable all but one processor in an SMP-enabled kernel on an SMP machine? We'd like to do some measurements comparing performance of an application running on one cpu vs. two cpus, without the need to reboot between a UP kernel and SMP kernel. Is this possible?
