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. SEE ALSO
