detecting SMP CPU

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hallo, util-linux,

I want to detect the existence of an SMP CPU (multi core CPU). I've  
tried the contents of "/proc/cpuinfo" and the output of "lscpu".

Both ways only showed the existence of both processors of my AMD CPU  
when I run them under a kernel which was compiled with the option  
"SMP=Y".

The "help" for this kernel option proposes to set this option only if  
the kernel really runs on such a CPU.

Is there any way to detect a multi core CPU under a kernel which is  
compiled with "SMP=n"?

Please excuse my gerlish.

Viele Gruesse!
Helmut
