|

|
|
.Pp
|
||
|
|
Devinfo with no arguments passed, shows the lists of devices using indentation
|
||
|
|
and how they are reached from the device
|
||
|
|
.Em nexus .
|
||
|
|
.Pp
|
||
|
|
The following command line arguments are accepted. When no command line
|
||
|
|
argument(s) are passed,
|
||
|
|
.Xr devinfo 8
|
||
|
|
simply prints the hierarchy of the device table.
|
||
|
|
.Bl -bullet -width indent
|
||
|
|
.It
|
||
|
|
.Op -r :
|
||
|
|
causes hardware resource information (such as IRQ, I/O ports, I/O memory
|
||
|
|
addresses) to be listed, under each device that has reserved those resources.
|
||
|
|
.It
|
||
|
|
.Op -u :
|
||
|
|
displays the same information as
|
||
|
|
.Op -r ,
|
||
|
|
but sorts by resource type rather than by device, allowing you to review the
|
||
|
|
set of system resources for usage and available resources. I.e., it lists all
|
||
|
|
the IRQ consumers together.
