Quad CPU Setup? How do I check if it worked.

**x0054** · 04-03-2005

Hi guys. I have a system running 2 CPUs at the moment, will be up to 4 by monday (I am expecting VRMs to arrive). What I am wondering is how do I check if Linux has recognized and is using all of the CPUs? I looked as the couinfo file, but it only shows info about one cpu

Here is the output:

Code:

root@glisan&#58;/proc# cat cpuinfo
processor       &#58; 0
vendor_id       &#58; GenuineIntel
cpu family      &#58; 6
model           &#58; 5
model name      &#58; Pentium II &#40;Deschutes&#41;
stepping        &#58; 3
cpu MHz         &#58; 449.867
cache size      &#58; 512 KB
fdiv_bug        &#58; no
hlt_bug         &#58; no
f00f_bug        &#58; no
coma_bug        &#58; no
fpu             &#58; yes
fpu_exception   &#58; yes
cpuid level     &#58; 2
wp              &#58; yes
flags           &#58; fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov pat pse36 mmx fxsr
bogomips        &#58; 897.84

Is there another way to check this? Do I need to configure anything in the kernel to get linux to recognize my other CPUs? I am running Slackware 10.1

Thank you for any help,

Slackware comes without SMP enabled by default. So if you did not compile your own kernel, enabling this feature it won't be supported.

See if dmesg shows info about your CPU's .

Yeah, I just checked. The multiple CPU support is not turned on. Is there a place I can download a kernel image with SMP and Compaq RIDE controller compiled in. I can compile my own kernel but that's going to take for ever considering that it's only going to be running on a single CPU.

Not that I'm aware off, so try to make your own. I had a Celeron 400A (PII) and it took a couple of hours to compile a new kernel but it is not that long.
