It shows the heirarchical registry structure as an inverted tree. The provider-client relationships among those objects is shown as follows: .Pp +-o provider | +-o client .Pp By default, object properties are not shown. The use of the .Fl c , .Fl k , .Fl l , or .Fl n options cause .Nm to show properties for objects that match the specified criteria. .Pp By supplying the .Fl r option, the user may specify the object which will appear at the root of the tree with the .Fl c , .Fl k , or .Fl n options. If root matches more than one object, multiple trees will be displayed. .Pp The options are as follows: .Pp .Bl -tag -width flag .It Fl b Show the object name in bold. .It Fl c Show the object properties only if the object is an instance of, or derives from, the specified C++ .Ar class (e.g. IOService). .It Fl d Limit tree traversal to the specified .Ar depth . The depth limit is applied with respect to each subtree root individually. Therefore, supplying a depth of 1 will cause .Nm to display only (sub)tree root nodes; children will not be shown. .It Fl f Enable smart formatting. .Nm knows how to format certain properties so that the output is more readable and meaningful, decoding data fields where appropriate. Currently supported are `reg', `assigned-addresses', `slot-names', `ranges', `interrupt-map', `interrupt-parent`, and `interrupts'. .It Fl i Show the object inheritance. .It Fl k Show the object properties only if the object has the specified .Ar key . Substrings do not match; the specified key must be a full property name. .It Fl l Show properties for all displayed objects. .It Fl n Show the object properties only if the object has the specified .Ar name . The object location, if any, is considered part of the name, thus pci@f0000000 and pci@f4000000 are distinct names. .It Fl p Traverse the registry over the specified .Ar plane . The default plane value is ``IOService''. The other planes, such as ``IODeviceTree'', can be found under the ``IORegistryPlanes'' property of the root object (ioreg -d 1 -k IORegistryPlanes). .It Fl r Show subtrees rooted by objects that match the specified criteria. If none of .Fl c , .Fl k , or .Fl n are supplied, .Fl r has no effect. .It Fl s Show the object state (busy state, retain count). This is the default. .It Fl S Don't show the object state (busy state, retain count). .It Fl t Show tree location of each subtree. This option causes .Nm to display all nodes between the I/O Kit Root and the root of the displayed subtree, i.e. the subtree's parent, grandparent, etc. .It Fl w Clip the output to the specified line .Ar width . The default width value is the current screen size. A value of 0 specifies an unlimited line width. .It Fl x Show data and numbers as hexadecimal. .El
