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.

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.

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.

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.

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.

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.
