.Nd machine-dependent device autoconfiguration
.Sh SYNOPSIS
.In sys/systm.h
.Ft void
.Fn cpu_configure "void"
.Sh DESCRIPTION
The machine-dependent
.Fn 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
.Pq Dq mainbus .
When this function returns, interrupts must be enabled.
.Pp
The following tasks are performed by
.Fn cpu_configure :
.Bl -bullet -offset indent
.It
initialize soft interrupts (see
.Xr softint 9 ) ;
.It
initialize
.Tn CPU
interrupts and
.Tn SPLs
(see
.Xr spl 9 ) ;
.It
call
.Fn config_rootfound
for
.Dq mainbus ;
and
.It
complete any initialization deferred from
.Xr cpu_startup 9 .
