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.
