NAME
Tinker With Topologies. - Enumerations enum hwloc_restrict_flags_e { HWLOC_RESTRICT_FLAG_ADAPT_DISTANCES, HWLOC_RESTRICT_FLAG_ADAPT_MISC, HWLOC_RESTRICT_FLAG_ADAPT_IO } Functions hwloc_obj_t hwloc_topology_insert_misc_object_by_cpuset (hwloc_topology_t topology, hwloc_const_cpuset_t cpuset, const char *name) hwloc_obj_t hwloc_topology_insert_misc_object_by_parent (hwloc_topology_t topology, hwloc_obj_t parent, const char *name) int hwloc_topology_restrict (hwloc_topology_t restrict topology, hwloc_const_cpuset_t cpuset, unsigned long flags) Detailed Description Enumeration Type Documentation enum hwloc_restrict_flags_e Flags to be given to hwloc_topology_restrict(). Enumerator HWLOC_RESTRICT_FLAG_ADAPT_DISTANCES Adapt distance matrices according to objects being removed during restriction. If this flag is not set, distance matrices are removed. HWLOC_RESTRICT_FLAG_ADAPT_MISC Move Misc objects to ancestors if their parents are removed during restriction. If this flag is not set, Misc objects are removed when their parents are removed. HWLOC_RESTRICT_FLAG_ADAPT_IO Move I/O objects to ancestors if their parents are removed during restriction. If this flag is not set, I/O devices and bridges are removed when their parents are removed. Function Documentation hwloc_obj_t hwloc_topology_insert_misc_object_by_cpuset (hwloc_topology_ttopology, hwloc_const_cpuset_tcpuset, const char *name) Add a MISC object to the topology. A new MISC object will be created and inserted into the topology at the position given by bitmap cpuset. This offers a way to add new intermediate levels to the topology hierarchy. cpuset and name will be copied to setup the new object attributes. Returns: the newly-created object. NULL if the insertion conflicts with the existing topology tree. Note: If name contains some non-printable characters, they will be dropped when exporting to XML, see hwloc_topology_export_xml(). hwloc_obj_t hwloc_topology_insert_misc_object_by_parent (hwloc_topology_ttopology, hwloc_obj_tparent, const char *name) Add a MISC object as a leaf of the topology. A new MISC object will be created and inserted into the topology at the position given by parent. It is appended to the list of existing children, without ever adding any intermediate hierarchy level. This is useful for annotating the topology without actually changing the hierarchy. name will be copied to the setup the new object attributes. However, the new leaf object will not have any cpuset. Returns: the newly-created object Note: If name contains some non-printable characters, they will be dropped when exporting to XML, see hwloc_topology_export_xml(). int hwloc_topology_restrict (hwloc_topology_t restricttopology, hwloc_const_cpuset_tcpuset, unsigned longflags) Restrict the topology to the given CPU set. Topology topology is modified so as to remove all objects that are not included (or partially included) in the CPU set cpuset. All objects CPU and node sets are restricted accordingly. flags is a OR'ed set of hwloc_restrict_flags_e. Note: This call may not be reverted by restricting back to a larger cpuset. Once dropped during restriction, objects may not be brought back, except by loading another topology with hwloc_topology_load(). Returns: 0 on success. -1 with errno set to EINVAL if the input cpuset is invalid. The topology is not modified in this case. -1 with errno set to ENOMEM on failure to allocate internal data. The topology is reinitialized in this case. It should be either destroyed with hwloc_topology_destroy() or configured and loaded again.
