Subject: Detecting x86 SMP on a UP kernel
Date: Sun, 29 Jul 2001 03:43:54 +0100	[thread overview]
Message-ID: <20010729034354.A65028@compsoc.man.ac.uk> (raw)


Hi, I need to be able to detect underlying x86 SMP hardware
when running a UP kernel, from a module.

This is to avoid trashing the APIC setup on SMP hardware (normally
I have to enable the APIC, re-do the fixmap etc. so I can use the local
APIC with a stock kernel).

I don't want to require a kernel patch if possible (I suppose just 
EXPORT_SYMBOL(smp_found_config) would do ...).

So can someone give me a hint on how I can detect underlying SMP hardware ?

I wouldn't need to do this if the ac tree APIC patches were in the kernel btw

thanks
john
