static hwloc_obj_t hwloc_get_cache_covering_cpuset (hwloc_topology_t topology, hwloc_const_cpuset_t set) [inline], [static]

Get the first data (or unified) cache covering a cpuset set.

Returns

static int hwloc_get_cache_type_depth (hwloc_topology_t topology, unsigned cachelevel, hwloc_obj_cache_type_t cachetype) [inline], [static]

Find the depth of cache objects matching cache level and type. Return the depth of the topology level that contains cache objects whose attributes match cachelevel and cachetype.

This function is identical to calling hwloc_get_type_depth() with the corresponding type such as HWLOC_OBJ_L1ICACHE, except that it may also return a Unified cache when looking for an instruction cache.

If no cache level matches, HWLOC_TYPE_DEPTH_UNKNOWN is returned.

If cachetype is HWLOC_OBJ_CACHE_UNIFIED, the depth of the unique matching unified cache level is returned.

If cachetype is HWLOC_OBJ_CACHE_DATA or HWLOC_OBJ_CACHE_INSTRUCTION, either a matching cache, or a unified cache is returned.

If cachetype is -1, it is ignored and multiple levels may match. The function returns either the depth of a uniquely matching level or HWLOC_TYPE_DEPTH_MULTIPLE.

static hwloc_obj_t hwloc_get_shared_cache_covering_obj (hwloc_topology_t topology, hwloc_obj_t obj) [inline], [static]

Get the first data (or unified) cache shared between an object and somebody else.

Returns
