.Sh DESCRIPTION
|
|
The
|
|
.Nm
|
|
utility, without any arguments, shows the hierarchy of devices available
|
|
in the syste, starting from the
|
|
.Dq nexus
|
|
device.
|
|
.Pp

|
The following options are accepted.
|
|
.Bl -tag -width indent
|
|
.It Fl 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.
|
|
.It Fl u
|
|
Displays the same information as with
|
|
.Fl 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.
