Detailed Description

Function Documentation

◆ hwloc_bridge_covers_pcibus()

static int hwloc_bridge_covers_pcibus ( hwloc_obj_t  bridge,
unsigned  domain,
unsigned  bus 
)
inlinestatic

◆ hwloc_get_next_bridge()

static hwloc_obj_t hwloc_get_next_bridge ( hwloc_topology_t  topology,
hwloc_obj_t  prev 
)
inlinestatic

Get the next bridge in the system.

Returns
the first bridge if prev is NULL.

◆ hwloc_get_next_osdev()

static hwloc_obj_t hwloc_get_next_osdev ( hwloc_topology_t  topology,
hwloc_obj_t  prev 
)
inlinestatic

Get the next OS device in the system.

Returns
the first OS device if prev is NULL.

◆ hwloc_get_next_pcidev()

static hwloc_obj_t hwloc_get_next_pcidev ( hwloc_topology_t  topology,
hwloc_obj_t  prev 
)
inlinestatic

Get the next PCI device in the system.

Returns
the first PCI device if prev is NULL.

◆ hwloc_get_non_io_ancestor_obj()

static hwloc_obj_t hwloc_get_non_io_ancestor_obj ( hwloc_topology_t  topology,
hwloc_obj_t  ioobj 
)
inlinestatic

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.

◆ hwloc_get_pcidev_by_busid()

static hwloc_obj_t hwloc_get_pcidev_by_busid ( hwloc_topology_t  topology,
unsigned  domain,
unsigned  bus,
unsigned  dev,
unsigned  func 
)
inlinestatic

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

◆ hwloc_get_pcidev_by_busidstring()

static hwloc_obj_t hwloc_get_pcidev_by_busidstring ( hwloc_topology_t  topology,
const char *  busid 
)
inlinestatic

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