hwloc-annotate: Add info attributes to a XML topology
NAMEhwloc-annotate - Add info attributes to a XML topology
SYNOPSIShwloc-annotate [options] <input.xml> <output.xml> <location> <mode> <annotation>
- Remove all info attributes that exist with the same name before adding the new one. This option is only accepted in "info" mode. If the info value is omitted, existing infos are replaced with nothing.
- Clear the existing info attributes in the target objects before annotating. If no new annotation has to be added after clearing, mode should be set to none.
DESCRIPTIONhwloc-annotate loads a topology from a XML file, adds some annotations, and export the resulting topology to another XML file. The input and output files may be the same.
The annotation may be string info attributes. This is specified by the mode:
- info <name> <value>
- Specifies a new string info attribute whose name is name and value is value.
- misc <name>
- Specifies a new Misc object name.
- No new annotation is added. This is useful when clearing existing attributes.
Annotations may be added to one specific object in the topology, all of them, or all of a given type. This is specified by the location:
- annotates all objects in the topology.
- annotates the root object of the topology.
- annotates all objects of the given type.
- annotates the object of the given type and index. The index is logical.
NOTE: The existing annotations may be listed with hwloc-info.
hwloc-annotate's operation is best described through several examples.
Add an info attribute to all Core objects:
Add a Misc object named "foobar" under the root object of the topology and modify the input XML directly:
Add an info attribute to OS device #2 and #3:
