I was wondering how can I check on my running machine, whether the kernel is configured for SMP or not? Of course, I can look into the kernel .config file and can search for it. But, the question is let's say I don't have a source code, how will I check the SMP configuration? Is there any proc file to check it?
The following says that I have no multi-cores:
#cat /proc/cpuinfo
processor : 1
cpu model : Broadcom BMIPS5000 V1.1 FPU V0.1
BogoMIPS : 651.26
cpu MHz : 1305.018
wait instruction : yes
microsecond timers : yes
tlb_entries : 64
extra interrupt vector : yes
hardware watchpoint : no
ASEs implemented :
shadow register sets : 1
kscratch registers : 0
core : 0
VCED exceptions : not available
VCEI exceptions : not available
The output of uname -a says:
Linux 136.170.193.3 3.3.8-2.4 #2 SMP Fri Dec 13 07:11:03 EST 2013 mips GNU/Linux
A bit confusing here. Someone on the comments suggested me to check uname -a . I am not sure whether the results are reliable or not. Can I assume that with the keyword SMP produced by uname -a, the kernel is configured as SMP?
