NAME

     cpu_configure -- machine-dependent device autoconfiguration


SYNOPSIS

     #include <sys/systm.h>

     void
     cpu_configure(void);


DESCRIPTION

     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 func-
     tion returns, interrupts must be enabled.

     cpu_configure() performs the following tasks:

     ·   initialize soft interrupts (see softintr(9))

     ·   initialize CPU interrupts and SPLs

     ·   call config_rootfound() for "mainbus"

     ·   complete any initialization deferred from cpu_startup().
