Dedicated Interrupt handling on SMP
I'm trying to find the easiest way to to deidcate one CPU to responding to a specific Interrupt request. That CPU should only listen for that request while all other CPU should ignore the interrupt. Any suggestions? Do I have to muck with the IO_APIC or is there a simpler way which I just missed? Any help would be appreciated! Thank you!
