+.Sh NAME
+.Nm cpu_configure
+.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 .
