NAME

       hwloc-annotate - Add info attributes to a XML topology

SYNOPSIS

       hwloc-annotate [options] <input.xml> <output.xml> <location> <mode> <annotation>

       Note  that  hwloc(7)  provides  a  detailed  explanation  of the hwloc system and of valid
       <location> formats; it should be read before reading this man page.

OPTIONS

       --ri      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.

       --ci      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.

       --cu      Clear  the existing userdata from the target objects.  If nothing else has to be
                 performed after clearing, mode should be set to none.

DESCRIPTION

       hwloc-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.

       none   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 (see also EXAMPLES below).  Objects may  be
       specified  as location tuples, as explained in hwloc(7).  However hexadecimal bitmasks are
       not accepted since they may correspond to multiple objects.

       NOTE: The existing annotations may be listed with hwloc-info.

       NOTE: It is highly recommended that you read the hwloc(7)  overview  page  before  reading
       this  man  page.   Most of the concepts described in hwloc(7) directly apply to the hwloc-
       annotate utility.

EXAMPLES

       hwloc-annotate's operation is best described through several examples.

       Add an info attribute to all Core objects:

           $ hwloc-annotate input.xml output.xml Core:all info infoname infovalue

       Add a Misc object named "foobar" under the root object of  the  topology  and  modify  the
       input XML directly:

           $ hwloc-annotate file.xml file.xml root misc foobar

       Add an info attribute to OS device #2 and #3:

           $ hwloc-annotate input.xml output.xml os:2-3 info infoname infovalue

       Change package objects to green with red text in the lstopo graphical output:

           $     hwloc-annotate     topo.xml     topo.xml     package:all     info    lstopoStyle
       "Background=#00ff00;Text=#ff0000"
           $ lstopo -i topo.xml

RETURN VALUE

       Upon successful execution, hwloc-annotate generates the output topology.  The return value
       is 0.

       hwloc-annotate  will  return nonzero if any kind of error occurs, such as (but not limited
       to) failure to parse the command line.
