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

NAME
     devinfo -- print information about system device configuration

SYNOPSIS
     devinfo [-ruv]

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.
