DEVINFO(8) FreeBSD System Manager's Manual DEVINFO(8)
NAME
devinfo - print information about system device configuration
SYNOPSIS
devinfo [-rv]
devinfo -u
devinfo -p dev [-v]
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. This flag also displays verbose
information about each device.
-p dev Display the path of dev back to the root of the device tree.
