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.

           the next bridge if prev is not NULL.

           NULL if there is no next bridge.

   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.

           the next OS device if prev is not NULL.

           NULL if there is no next OS device.

   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.

           the next PCI device if prev is not NULL.

           NULL if there is no next PCI device.

   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.

       Returns
           a non-I/O object.

       Note
           This function cannot return NULL.

           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.

       Returns
           a matching PCI device object if any, NULL otherwise.

   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.

       Returns
           a matching PCI device object if any, NULL otherwise.
