hwlocality_helper_types - Kinds of object Type


int hwloc_obj_type_is_normal (hwloc_obj_type_t type)
int hwloc_obj_type_is_io (hwloc_obj_type_t type)
int hwloc_obj_type_is_memory (hwloc_obj_type_t type)
int hwloc_obj_type_is_cache (hwloc_obj_type_t type)
int hwloc_obj_type_is_dcache (hwloc_obj_type_t type)
int hwloc_obj_type_is_icache (hwloc_obj_type_t type)

Each object type is either Normal (i.e. hwloc_obj_type_is_normal() returns 1), or Memory (i.e. hwloc_obj_type_is_memory() returns 1) or I/O (i.e. hwloc_obj_type_is_io() returns 1) or Misc (i.e. equal to HWLOC_OBJ_MISC). It cannot be of more than one of these kinds.

Check whether an object type is a CPU Cache (Data, Unified or Instruction). Memory-side caches are not CPU caches.

Returns

1 if an object of type type is a Cache, 0 otherwise.

Check whether an object type is a CPU Data or Unified Cache. Memory-side caches are not CPU caches.

Returns

1 if an object of type type is a CPU Data or Unified Cache, 0 otherwise.

Check whether an object type is a CPU Instruction Cache,. Memory-side caches are not CPU caches.

Returns

1 if an object of type type is a CPU Instruction Cache, 0 otherwise.

Check whether an object type is I/O. I/O objects are objects attached to their parents in the I/O children list. This current includes Bridges, PCI and OS devices.

Returns

1 if an object of type type is a I/O object, 0 otherwise.

Check whether an object type is Memory. Memory objects are objects attached to their parents in the Memory children list. This current includes NUMA nodes and Memory-side caches.

Returns

1 if an object of type type is a Memory object, 0 otherwise.

Check whether an object type is Normal. Normal objects are objects of the main CPU hierarchy (Machine, Package, Core, PU, CPU caches, etc.), but they are not NUMA nodes, I/O devices or Misc objects.

They are attached to parent as Normal children, not as Memory, I/O or Misc children.

Returns

1 if an object of type type is a Normal object, 0 otherwise.
