DESCRIPTION
ioreg displays the I/O Kit registry. It shows the heirarchical registry structure as an inverted tree. The provider-client relationships among those objects is shown as follows: +-o provider | +-o client By default, object properties are not shown. The use of the -c, -k, -l, or -n options cause ioreg to show properties for objects that match the specified criteria. By supplying the -r option, the user may specify the object which will appear at the root of the tree with the -c, -k, or -n options. If root matches more than one object, multiple trees will be displayed. The options are as follows: -a Archive the output in XML. -b Show the object name in bold. -c Show the object properties only if the object is an instance of, or derives from, the specified C++ class (e.g. IOService). -d Limit tree traversal to the specified depth. The depth limit is applied with respect to each subtree root individually. Therefore, supplying a depth of 1 will cause ioreg to display only (sub)tree root nodes; children will not be shown. -f Enable smart formatting. ioreg 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'. -i Show the object inheritance. -k Show the object properties only if the object has the specified key. Substrings do not match; the specified key must be a full property name. -l Show properties for all displayed objects. -n Show the object properties only if the object has the specified name. The object location, if any, is considered part of the name, thus pci@f0000000 and pci@f4000000 are distinct names. -p Traverse the registry over the specified 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). -r Show subtrees rooted by objects that match the specified criteria. If none of -c, -k, or -n are supplied, -r has no effect. -t Show tree location of each subtree. This option causes ioreg 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. -w Clip the output to the specified line width. The default width value is the current screen size. A value of 0 specifies an unlimited line width. -x Show data and numbers as hexadecimal.
