CONFIG_SMP?

I want to get it without accessing config file or proc.

uname -a may give you the answer you are looking for.

prasad@prasad-desktop:~/LinuxSrc/linux- 2.6.20$ uname -a
Linux prasad-desktop 2.6.20 #8 SMP Thu Feb 15 16:00:00 IST 2007 i686 GNU/Linux

 

In kernel space ? In a kernel module ?

if CONFIG_SMP is defined then you are in SMP mode else not in SMP mode.

#if defined(CONFIG_SMP)
    then SMP mode
