Hi there,
I've just installed PC-BSD 0.7.8 and I was wondering if it supports SMP.
I am running a 2xPIII@850MHz, no hyperthreading.
Does the default kernel support SMP or I have to dowload the source from cvs and recompile? How can I guess that SMP is enabled?
Thanks for reply.

pc-bsd supports smp. you have to download the sources and recompile the kernel.

http://www.freebsd.org/doc/en_US.ISO885 ... onfig.html (http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/kernelconfig-config.html)

please check the dmesg output.

just wondering... what happens if one uses a smp kernel with one processor?

does it work?

Is there a effenciency decrease?

Does hyperthreading work on a 1p kernel?


Thanks in advance!

Cheers!

the smp kernel works on a single processor. efficiency decrease? maybe, i don't know.

you need an smp kernel for hyperthreading.

Then perhaps the default supplied kernel should have smp functionality as standard if there is no efficiency decrease.

in freebsd 5.2.1 smp was in the default-kernel.

You got my point perfectly

I have a Dual cpu PC, an old AP400 Compaq workstation, I have now set up the smp kernel.

Being new to BSD, I found the following link explained the process step by step.

http://michael-and-mary.net/intro/?q=node/23

I started from the 'Updating source code, ports tree and docs' section about a 1/4 of the way down.

Good site, not sure if i agree with the anit pbi stance expressed there, but a great tutoral by any measure.

I needed a line thats not inthe guide I posted above, but is in the 1st link

Besure to have option SMP in your kernel config file.
