DEVINFO(8)		FreeBSD	System Manager's Manual		    DEVINFO(8)

NAME
     devinfo --	print information about	system device configuration

SYNOPSIS
     devinfo [-rv]
     devinfo -u

DESCRIPTION
     The devinfo utility, without any arguments, shows the hierarchy of
     devices available in the system, starting from the	``nexus'' device.

     The following options are accepted.

     -r	     Causes hardware resource information (such	as IRQ,	I/O ports, I/O
	     memory addresses) to be also listed, under	each device that has
	     reserved those resources.

     -u	     Displays the same information as with -r but sorts	by resource
	     type rather than by device, allowing to review the	set of system
	     resources by usage	and available resources.  I.e.,	it lists all
	     the IRQ consumers together.

     -v	     Display all devices in the	driver tree, not just those that are
	     attached or busy.	Without	this flag, only	those devices that
	     have attached are reported.
