Detailed Description
Function Documentation
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
NULL
if no cache matches.
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.
