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.
