DEVINFO(8)             DragonFly 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 enabled devices in the driver tree, not just those
             that are attached or busy.  Specify this flag twice, to also
             display all disabled devices in the driver tree.  Without this
             flag, only those devices that have attached are reported.
