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).
