Detailed Description

Function Documentation

   static int hwloc_bridge_covers_pcibus (hwloc_obj_t bridge, unsigned domain, unsigned bus)
       [inline],  [static]
   static hwloc_obj_t hwloc_get_next_bridge (hwloc_topology_t topology, hwloc_obj_t prev)
       [inline],  [static]
       Get the next bridge in the system.

       Returns
           the first bridge if prev is NULL.

   static hwloc_obj_t hwloc_get_next_osdev (hwloc_topology_t topology, hwloc_obj_t prev)
       [inline],  [static]
       Get the next OS device in the system.

       Returns
           the first OS device if prev is NULL.

   static hwloc_obj_t hwloc_get_next_pcidev (hwloc_topology_t topology, hwloc_obj_t prev)
       [inline],  [static]
       Get the next PCI device in the system.

       Returns
           the first PCI device if prev is NULL.

   static hwloc_obj_t hwloc_get_non_io_ancestor_obj (hwloc_topology_t topology, hwloc_obj_t
       ioobj) [inline],  [static]
       Get the first non-I/O ancestor object. Given the I/O object ioobj, find the smallest non-
       I/O ancestor object. This object (normal or memory) may then be used for binding because
       it has non-NULL CPU and node sets and because its locality is the same as ioobj.

       Note
           The resulting object is usually a normal object but it could also be a memory object
           (e.g. NUMA node) in future platforms if I/O objects ever get attached to memory
           instead of CPUs.

   static hwloc_obj_t hwloc_get_pcidev_by_busid (hwloc_topology_t topology, unsigned domain,
       unsigned bus, unsigned dev, unsigned func) [inline],  [static]
       Find the PCI device object matching the PCI bus id given domain, bus device and function
       PCI bus id.

   static hwloc_obj_t hwloc_get_pcidev_by_busidstring (hwloc_topology_t topology, const char *
       busid) [inline],  [static]
       Find the PCI device object matching the PCI bus id given as a string xxxx:yy:zz.t or
       yy:zz.t.
