◆ hwloc_get_next_bridge()
Get the next bridge in the system.
- Returns
- the first bridge if
prev is NULL .
-
the next bridge if
prev is not NULL .
-
NULL if there is no next bridge.
◆ hwloc_get_next_osdev()
Get the next OS device in the system.
- Returns
- the first OS device if
prev is NULL .
-
the next OS device if
prev is not NULL .
-
NULL if there is no next OS device.
◆ hwloc_get_next_pcidev()
Get the next PCI device in the system.
- Returns
- the first PCI device if
prev is NULL .
-
the next PCI device if
prev is not NULL .
-
NULL if there is no next PCI device.
◆ hwloc_get_non_io_ancestor_obj()
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 .
- Returns
- a non-I/O object.
- Note
- This function cannot return
NULL .
-
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()
Find the PCI device object matching the PCI bus id given domain, bus device and function PCI bus id.
- Returns
- a matching PCI device object if any,
NULL otherwise.
◆ hwloc_get_pcidev_by_busidstring()
Find the PCI device object matching the PCI bus id given as a string xxxx:yy:zz.t or yy:zz.t.
- Returns
- a matching PCI device object if any,
NULL otherwise.
