NAME
       hwlocality_openfabrics - Interoperability with OpenFabrics

   Functions
       static int hwloc_ibv_get_device_cpuset (hwloc_topology_t topology,
           struct ibv_device *ibdev, hwloc_cpuset_t set)
       static hwloc_obj_t hwloc_ibv_get_device_osdev_by_name (hwloc_topology_t
           topology, const char *ibname)
       static hwloc_obj_t hwloc_ibv_get_device_osdev (hwloc_topology_t
           topology, struct ibv_device *ibdev)

Detailed Description
       This interface offers ways to retrieve topology information about
       OpenFabrics devices.

Function Documentation
   static int hwloc_ibv_get_device_cpuset (hwloc_topology_t topology, struct
       ibv_device * ibdev, hwloc_cpuset_t set) [inline],  [static]
       Get the CPU set of logical processors that are physically close to
       device ibdev. Return the CPU set describing the locality of the
       OpenFabrics device ibdev.

       Topology topology and device ibdev must match the local machine. I/O
       devices detection is not needed in the topology.

       The function only returns the locality of the device. If more
       information about the device is needed, OS objects should be used
       instead, see hwloc_ibv_get_device_osdev() and
       hwloc_ibv_get_device_osdev_by_name().

       This function is currently only implemented in a meaningful way for
       Linux; other systems will simply get a full cpuset.

   static hwloc_obj_t hwloc_ibv_get_device_osdev (hwloc_topology_t topology,
       struct ibv_device * ibdev) [inline],  [static]
       Get the hwloc OS device object corresponding to the OpenFabrics device
       ibdev. Return the OS device object describing the OpenFabrics device
       ibdev. Returns NULL if there is none.

       Topology topology and device ibdev must match the local machine. I/O
       devices detection must be enabled in the topology. If not, the locality
       of the object may still be found using hwloc_ibv_get_device_cpuset().

       Note:
           The corresponding PCI device object can be obtained by looking at
           the OS device parent object.

   static hwloc_obj_t hwloc_ibv_get_device_osdev_by_name (hwloc_topology_t
       topology, const char * ibname) [inline],  [static]
       Get the hwloc OS device object corresponding to the OpenFabrics device
       named ibname. Return the OS device object describing the OpenFabrics
       device whose name is ibname. Returns NULL if there is none. The name
       ibname is usually obtained from ibv_get_device_name().

       The topology topology does not necessarily have to match the current
       machine. For instance the topology may be an XML import of a remote
       host. I/O devices detection must be enabled in the topology.

       Note:
           The corresponding PCI device object can be obtained by looking at
           the OS device parent object.
