DEVINFO(8) BSD 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.
