Helpers for manipulating Linux libnuma nodemask_t

Functions

static inline int hwloc_cpuset_to_linux_libnuma_nodemask (hwloc_topology_t topology, hwloc_const_cpuset_t cpuset, nodemask_t *nodemask)
static inline int hwloc_nodeset_to_linux_libnuma_nodemask (hwloc_topology_t topology, hwloc_const_nodeset_t nodeset, nodemask_t *nodemask)
static inline int hwloc_cpuset_from_linux_libnuma_nodemask (hwloc_topology_t topology, hwloc_cpuset_t cpuset, const nodemask_t *nodemask)
static inline int hwloc_nodeset_from_linux_libnuma_nodemask (hwloc_topology_t topology, hwloc_nodeset_t nodeset, const nodemask_t *nodemask)

Detailed Description

Note:
The Linux libnuma nodemask_t interface is deprecated and its implementation is at least incorrect with respect to sparse NUMA node ids. It is strongly advised to use struct bitmask instead of nodemask_t, or even to use hwloc directly.

Function Documentation

static inline int hwloc_cpuset_from_linux_libnuma_nodemask ( hwloc_topology_t  topology,
hwloc_cpuset_t  cpuset,
const nodemask_t *  nodemask 
) [static]

Convert libnuma nodemask nodemask into hwloc CPU set cpuset.

This function may be used before calling some old libnuma functions that use a nodemask_t as an output parameter.

static inline int hwloc_cpuset_to_linux_libnuma_nodemask ( hwloc_topology_t  topology,
hwloc_const_cpuset_t  cpuset,
nodemask_t *  nodemask 
) [static]

Convert hwloc CPU set cpuset into libnuma nodemask nodemask.

This function may be used before calling some old libnuma functions that use a nodemask_t as an input parameter.

static inline int hwloc_nodeset_from_linux_libnuma_nodemask ( hwloc_topology_t  topology,
hwloc_nodeset_t  nodeset,
const nodemask_t *  nodemask 
) [static]

Convert libnuma nodemask nodemask into hwloc NUMA node set nodeset.

This function may be used before calling some old libnuma functions that use a nodemask_t as an output parameter.

static inline int hwloc_nodeset_to_linux_libnuma_nodemask ( hwloc_topology_t  topology,
hwloc_const_nodeset_t  nodeset,
nodemask_t *  nodemask 
) [static]

Convert hwloc NUMA node set nodeset into libnuma nodemask nodemask.

This function may be used before calling some old libnuma functions that use a nodemask_t as an input parameter.
