How is processor/cpu/thread affinity implemented at kernel level and hardware level??

[garik4788]

I have been investigating on how a kernel ensures that a thread is locked to a processor using affinity.


Is there a special opcode for that locking?

or

there has to be issue slot management on the part of the kernel for each machine instruction fed into the pipeline?

Thanks.

Please do not double post. You are asking a pretty high level question. Unless we have some CPU designers out there, you may be out of luck.
