.Sh DESCRIPTION
|
|
The
|
|
.Nm
|
|
utility is used to examine the Open Firmware device tree.
|
|
In the first synopsis form, the complete device tree is printed; in the
|
|
second form, only the selected
|
|
.Ar nodes
|
|
will be examined.
|
|
.Pp
|
|
The following options are available:
|
|
.Bl -tag -width ".Fl P Ar property"
|
|
.It Fl a
|
|
Print the complete device tree.
|
|
.It Fl p
|
|
Print all available properties.
|
|
.It Fl P Ar property
|
|
Only print properties of the given name.
|
|
.It Fl R
|
|
Print properties in
|
|
.Dq raw
|
|
format, i.e., omit all headings and indentation and just write the
|
|
property values unaltered to the standard output.
|
|
This is intended to be used with the
|
|
.Fl P
|
|
option to extract the value of a single property.
|
|
.It Fl S
|
|
Print properties as strings; this is analogous to the
|
|
.Fl R
|
|
option, except that each property is only output to the first
|
|
.Dv NUL
|
|
character, and that newline is appended to each.
|
|
.It Fl r
|
|
Recursively print all children of the specified nodes.
|
|
.El
|
|
.Sh EXAMPLES
|
|
Print the complete device tree:
|
|
.Pp
|
|
.Dl "ofwdump -a"
|
|
.Pp
|
|
Print the complete device subtree of the
|
|
.Dq Li /pci
|
|
node, including all available properties:
|
|
.Pp
|
|
.Dl "ofwdump -pr /pci"
|
|
.Pp
|
|
Print the
|
|
.Dq Li compatible
|
|
property of the
|
|
.Dq Li /pci
|
|
node as plain string:
|
|
.Pp
|
|
.Dl "ofwdump -P compatible -S /pci"
