Detailed Description¶

Function Documentation¶

static int hwloc_bridge_covers_pcibus ( hwloc_obj_tbridge, unsigneddomain, unsignedbus) [inline], [static]¶

static hwloc_obj_t hwloc_get_hostbridge_by_pcibus (hwloc_topology_ttopology, unsigneddomain, unsignedbus) [inline], [static]¶

Find the hostbridge that covers the given PCI bus. This is useful for finding the locality of a bus because it is the hostbridge parent cpuset.

static hwloc_obj_t hwloc_get_next_bridge (hwloc_topology_ttopology, hwloc_obj_tprev) [inline], [static]¶

Get the next bridge in the system. Returns:

static hwloc_obj_t hwloc_get_next_osdev (hwloc_topology_ttopology, hwloc_obj_tprev) [inline], [static]¶

Get the next OS device in the system. Returns:

static hwloc_obj_t hwloc_get_next_pcidev (hwloc_topology_ttopology, hwloc_obj_tprev) [inline], [static]¶

Get the next PCI device in the system. Returns:

static hwloc_obj_t hwloc_get_non_io_ancestor_obj (hwloc_topology_ttopology, hwloc_obj_tioobj) [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 regular object may then be used for binding because its locality is the same as ioobj.

static hwloc_obj_t hwloc_get_pcidev_by_busid (hwloc_topology_ttopology, unsigneddomain, unsignedbus, unsigneddev, unsignedfunc) [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.
