Detailed Description

Enumeration Type Documentation

  enum hwloc_backend_flag_e

Backend flags.

Enumerator

HWLOC_BACKEND_FLAG_NEED_LEVELS
    Levels should be reconnected before this backend discover() is used.

Function Documentation

  struct hwloc_backend* hwloc_backend_alloc (struct hwloc_disc_component * component)

Allocate a backend structure, set good default values, initialize backend->component and topology, etc. The caller will then modify whatever needed, and call hwloc_backend_enable().

  int hwloc_backend_enable (struct hwloc_topology * topology, struct hwloc_backend * backend)

Enable a previously allocated and setup backend.

  int hwloc_backends_get_obj_cpuset (struct hwloc_backend * caller, struct hwloc_obj * obj, hwloc_bitmap_t cpuset)

Used by backends discovery callbacks to request locality information from others. Traverse the list of enabled backends until one has a get_obj_cpuset() method, and call it.

  int hwloc_backends_notify_new_object (struct hwloc_backend * caller, struct hwloc_obj * obj)

Used by backends discovery callbacks to notify other backends of new objects. Traverse the list of enabled backends (all but caller) and invoke their notify_new_object() method to notify them that a new object just got added to the topology.

Currently only used for notifying of new PCI device objects.
