    Ive just started building my own kernels. I have a dual processor sun so would like to compile using both processors, does anyone know how I can adapt the command below to use both processors for the compile? Some info on what the command below is doing would be nice. why is there two cleans for instance? I got this "mantra" from dpkg on #debian


    make-kpkg clean && make-kpkg --initrd --append-to-version=.holway kernel_image modules_image clean && make-kpkg --initrd --append-to-version=.sly kernel_image modules_image

    Do you want to use both CPUs for the compile process, or is your uestion how to make an SMP kernel?

    I wanted to use both CPU's for the compile process. But I have since discovered

    export CONCURRENCY_LEVEL="3"
    where 3 is the number of cores +1

    This command is entered before make or kpkg and seems to set the -j variable.

    Perhaps someone can explain this better.
