Detailed Description

Function Documentation

static int hwloc_bridge_covers_pcibus (hwloc_obj_t bridge, unsigned domain,unsigned bus) [inline], [static]

static hwloc_obj_t hwloc_get_next_bridge (hwloc_topology_t topology,hwloc_obj_t prev) [inline], [static]

Get the next bridge in the system.

Returns

the first bridge if prev is NULL.

static hwloc_obj_t hwloc_get_next_osdev (hwloc_topology_t topology,hwloc_obj_t prev) [inline], [static]

Get the next OS device in the system.

Returns

the first OS device if prev is NULL.

static hwloc_obj_t hwloc_get_next_pcidev (hwloc_topology_t topology,hwloc_obj_t prev) [inline], [static]

Get the next PCI device in the system.

Returns

the first PCI device if prev is NULL.

static hwloc_obj_t hwloc_get_non_io_ancestor_obj (hwloc_topology_t topology,hwloc_obj_t ioobj) [inline], [static]

Get the first non-I/O ancestor object. Given the I/O object ioobj, find the smallest non-I/O ancestor object. This object (normal or memory) may then be used for binding because it has non-NULL CPU and node sets and because its locality is the same as ioobj.

Note

The resulting object is usually a normal object but it could also be a memory object (e.g. NUMA node) in future platforms if I/O objects ever get attached to memory instead of CPUs.

static hwloc_obj_t hwloc_get_pcidev_by_busid (hwloc_topology_t topology,unsigned domain, unsigned bus, unsigned dev, unsigned func) [inline],[static]

Find the PCI device object matching the PCI bus id given domain, bus device and function PCI bus id.

static hwloc_obj_t hwloc_get_pcidev_by_busidstring (hwloc_topology_ttopology, const char * busid) [inline], [static]

Find the PCI device object matching the PCI bus id given as a string xxxx:yy:zz.t or yy:zz.t.
