Re: SMP kernel configuration question?

Hi,

I have never configured a kernel for SMP before.

I turned on the obvious CONFIG_SMP=y in the .config but was prompted if I
would like to distribute interrupts (IRQs) across all CPUs.

What is the recommended setting for:

CONFIG_IRQ_ALL_CPUS

Any guidance here would be greatly appreciated.

Leave it to N. ideally, you should enable it, but I have experienced
lockups when this feature is enabled, I haven't yet figured out what's
going on (could be related to the lockup some users are experiencing
with SMP + HIGHMEM on some dual 800, let me know if you see the same).

Ben.
