[SOLVED] Adding a 2nd Processor

DewmSolo · Last edited by DewmSolo on Thu Jan 26, 2006 7:56 pm; edited 1 time in total

Good morning guys,

As some of yous might have read here in the forums, I got myself an Instellistation and it was powered by one Intel XEON 1.7Ghz. So I got started installing Gentoo on it. I have made it to this point so far:
-The whole thing is installed and running gentoo
-Installed KDE
-Recently installed Firefox

Being new to gentoo and though not new to linux, but shall I say quite unexperienced, it is taking me some time to take the steps forward. I'm currently reading on upgrading to gcc 3.4...I would also like to update from KDE3.4 to 3.5.... but all that is beside the point of this post.

The thing is that, I already have some work on there so I don't want to loose everything obviously.

I just received last night my 2nd CPU for that machine. Physical installation is done. CPU is installed, BIOS detected it, the BIOS health status shows it as doing very good.

So I would like to know what to do from here.....my guess is I should pull my current kernel config...which I forgot the name I saved it under, so if someone could remind where in the tree kernel configs are saved I would really appreciate. Once I have my current kernel config loaded in --menuconfig I would go to Processor Options and add support for symmetric something...don't remember the full name and then set the line underneath to say that I have 2 working CPUs in that machine.

From there what???? Recompile my kernel...fix my lilo bootloader.....and then what??? That's it??? My linux install will then use the 2 CPUs???

Thanks for your help guys.

All you need to do is activate the SMP option in your kernel config:

Kernel config will be found as .config in /usr/src/linux, or possibly in /proc as config.gz, depending upon how you configured your kernel.

Good evening guys,

Sorry that I haven't replied before now, but I haven't had time to touch my pc's at home since I posted my last message.

All I really wanted to say is: Thanks guys. Dewm Solo's XEON gentoo machine is now DUAL powered. :twisted:

Thanks for the help.

P.S.: Just a quick question here...I already solved the issue, but I'd like to know what happened. Why is it that I had to reconfigure Xorg after booting with the new kernel???
I did change the kernel of course....the last kernel had lots of stuff in there...so I removed a lot of extra stuff ...mostly modularized stuff for laptops though...which had nothing to do in this machine....I made no hardware changes and didn't change the kernel's driver settings....so I don't know....
