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_t
topology, 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.
