bsd.sp and bsd.mp kernels, how to compile?
The last time I followed the FAQ compiling kernels was on single processor machines. I just installed OpenBSD on my daily driver dual core Intel box. The kernel, userland, and xenocara compiles ran fine as usual. Then I realized DOH! I was running the sp kernel since I never had a machine where I needed the MP kernel before. I built the MP kernel and installed it. If I am following stable and want to have sp and mp kernels what order should I compile them in, does it matter? /jl -- ASCII ribbon campaign ( ) Powered by Lemote Fuloong against HTML e-mail X Loongson MIPS and OpenBSD and proprietary/ \http://www.mutt.org attachments / \ Code Blue or Go Home!

Re: bsd.sp and bsd.mp kernels, how to compile?
Thanks Paul. In that case I guess it would be simpler to do the sp kernel first since the make install causes it to get booted. Then when I do the mp kernel and install it everything will be ready to build the rest with the mp kernel. /jl On Sun, Dec 09, 2012 at 11:45:03AM +0100, Paul de Weerd wrote: On Sun, Dec 09, 2012 at 10:04:04AM +, John Long wrote: | The last time I followed the FAQ compiling kernels was on single processor | machines.

Why do you want to build the SP kernel if you're not going to use it ? If you're following stable, you may want to make a release and then use the kernels so produced. Alternatively, you can `make` GENERIC and `make install` GENERIC.MP.

Why do you want to build the SP kernel if you're not going to use it ? If I didn't stumble upon it I probably wouldn't even think about it. Now that I did I figured it would be good for testing once in a while if anything that appears to possibly be timing-related happens with the mp kernel. It only takes a few minutes to compile. If you're following stable, you may want to make a release and then use the kernels so produced. At this point this is the only AMD64 box I have OpenBSD on.
