|
inlinestatic |
Get the first cache covering a cpuset set
.
NULL
if no cache matches.

inlinestatic |
Find the depth of cache objects matching cache depth and type.
Return the depth of the topology level that contains cache objects whose attributes match cachedepth
and cachetype
. This function intends to disambiguate the case where hwloc_get_type_depth() returns HWLOC_TYPE_DEPTH_MULTIPLE
.
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
.

inlinestatic |
Get the first cache shared between an object and somebody else.
NULL
if no cache matches or if an invalid object is given.
