Usage: hwloc-info [ options ] [ object | root | levels | topology | support ... ]

Output options:
  --objects             Report information about specific objects
  --topology            Report information the topology
  --support             Report information about supported features
  -v --verbose          Include additional details
  -q --quiet -s         Reduce the amount of details to show
  --get-attr <name>     Only show the attribute line with name <name>
  --ancestors           Display the chain of ancestor objects up to the root
  --ancestor <type>     Only display the ancestor of the given type
  --children            Display all children
  --descendants <type>  Only display descendants of the given type
  --local-memory        Only display the local memory nodes
  --local-memory-flags <x>   Change flags for selecting local memory nodes
  --best-memattr <attr> Only display the best target among the local nodes
  --default-nodes       Only display the default local nodes
  --first               Only report the first matching object
  -n                    Prefix each line with the index of the considered object
Object filtering options:
  --restrict [nodeset=]<bitmap>
                        Restrict the topology to some processors or NUMA nodes.
  --restrict binding    Restrict the topology to the current process binding
  --restrict-flags <n>  Set the flags to be used during restrict
  --filter <type>:<knd> Filter objects of the given type, or all.
     <knd> may be `all' (keep all), `none' (remove all), `structure' or `important'
  --no-icaches          Do not show instruction caches
  --no-io               Do not show any I/O device or bridge
  --no-bridges          Do not any I/O bridge except hostbridges
  --whole-io            Show all I/O devices and bridges
Input options:
  --input <XML file>
  -i <XML file>         Read topology from XML file <path>
  --input <directory>
  -i <directory>        Read topology from chroot containing the /proc and /sys
                        of another system
  --input <directory>
  -i <directory>        Read topology from directory containing a CPUID dump
  --input "node:2 2"
  -i "node:2 2"         Simulate a fake hierarchy, here with 2 NUMA nodes of 2
                        processors
  --input-format <format>
  --if <format>         Enforce input format among xml, fsroot, cpuid, synthetic
  --thissystem          Assume that the input topology provides the topology
                        for the system on which we are running
  --pid <pid>           Detect topology as seen by process <pid>
  --disallowed          Include objects disallowed by administrative limitations
  -l --logical          Use logical object indexes for input (default)
  -p --physical         Use physical object indexes for input
Miscellaneous options:
  --version             Report version and exit
  -h --help             Show this usage
