NAME
- devinfo - print information about system device configura
- tion
SYNOPSIS
devinfo [-ruv]
DESCRIPTION
- The devinfo utility, without any arguments, shows the hier
- archy 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 de
- vice 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 de
- vices that
have attached are reported.
