NAME

     cpu_configure -- machine-dependent device autoconfiguration


SYNOPSIS

     #include <sys/systm.h>

     void
     cpu_configure(void);


DESCRIPTION

     The machine-dependent cpu_configure() is called during system bootstrap
     to perform the machine-dependent portion of device autoconfiguration.  It
     sets the configuration machinery in motion by finding the root bus
     (``mainbus'').  When this function returns, interrupts must be enabled.

     The following tasks are performed by cpu_configure():

           ·   initialize soft interrupts (see softint(9));

           ·   initialize CPU interrupts and SPLs (see spl(9));

           ·   call config_rootfound() for ``mainbus''; and

           ·   complete any initialization deferred from cpu_startup(9).
