# 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).
