static inline hwloc_obj_t hwloc_get_ancestor_obj_by_depth | ( | hwloc_topology_t topology | , |
unsigned | depth, | ||
hwloc_obj_t | obj | ||
) | [static] |
Returns the ancestor object of obj
at depth depth
.
static inline hwloc_obj_t hwloc_get_ancestor_obj_by_type | ( | hwloc_topology_t topology | , |
hwloc_obj_type_t | type, | ||
hwloc_obj_t | obj | ||
) | [static] |
Returns the ancestor object of obj
with type type
.
static inline hwloc_obj_t hwloc_get_common_ancestor_obj | ( | hwloc_topology_t topology | , |
hwloc_obj_t | obj1, | ||
hwloc_obj_t | obj2 | ||
) | [static] |
Returns the common parent object to objects lvl1 and lvl2.
static inline hwloc_obj_t hwloc_get_next_child | ( | hwloc_topology_t topology | , |
hwloc_obj_t | parent, | ||
hwloc_obj_t | prev | ||
) | [static] |
Return the next child.
If prev
is NULL
, return the first child.
static inline hwloc_obj_t hwloc_get_next_obj_by_depth | ( | hwloc_topology_t | topology, |
unsigned | depth, | ||
hwloc_obj_t | prev | ||
) | [static] |
Returns the next object at depth depth
.
If prev
is NULL
, return the first object at depth depth
.
static inline hwloc_obj_t hwloc_get_next_obj_by_type | ( | hwloc_topology_t | topology, |
hwloc_obj_type_t | type, | ||
hwloc_obj_t | prev | ||
) | [static] |
Returns the next object of type type
.
If prev
is NULL
, return the first object at type type
. If there are multiple or no depth for given type, return NULL
and let the caller fallback to hwloc_get_next_obj_by_depth().
static inline hwloc_obj_t hwloc_get_pu_obj_by_os_index | ( | hwloc_topology_t | topology, |
unsigned | os_index | ||
) | [static] |
Returns the object of type HWLOC_OBJ_PU with os_index
.
os_index
field of object should most of the times only be used for pretty-printing purpose. Type HWLOC_OBJ_PU is the only case where os_index
could actually be useful, when manually binding to processors. However, using CPU sets to hide this complexity should often be preferred. static inline hwloc_obj_t hwloc_get_root_obj | ( | hwloc_topology_t | topology | ) | [static] |
Returns the top-object of the topology-tree.
Its type is typically HWLOC_OBJ_MACHINE but it could be different for complex topologies. This function replaces the old deprecated hwloc_get_system_obj().
static inline int hwloc_obj_is_in_subtree | ( | hwloc_topology_t topology | , |
hwloc_obj_t | obj, | ||
hwloc_obj_t | subtree_root | ||
) | [static] |
Returns true if obj
is inside the subtree beginning with subtree_root
.
obj
and subtree_root
have a cpuset
.
