Subject: [oc] Hardware support for SMP
Hi all,
I have not clear which hardware support should an embedded CPU
provide to make it possible for an OS (like Linux) to support
Symmetric Multi-Processing.
Is it a matter of special signal lines, interrupts, or what else?
And then, is there any standard approach supported by the Linux
kernel, or every CPU vendor implements its own protocol, that
then has to be incorporated into the kernel sources?
Around the net I've found a lot of documents about Intel micros
(the solution seems to be the Advanced Programmable Interrupt
Controller, a.k.a. APIC), but nothing about MIPS or PowerPC.
Cheers,
Fabrizio
