static __hwloc_inline hwloc_obj_t | hwloc_get_pcidev_by_busid (hwloc_topology_t topology, unsigned domain, unsigned bus, unsigned dev, unsigned func) |
Find the PCI device object matching the PCI bus id given domain, bus device and function PCI bus id. | |
static __hwloc_inline hwloc_obj_t | hwloc_get_pcidev_by_busidstring (hwloc_topology_t topology, const char *busid) |
Find the PCI device object matching the PCI bus id given as a string xxxx:yy:zz.t or yy:zz.t. | |
static __hwloc_inline hwloc_obj_t | hwloc_get_next_osdev (hwloc_topology_t topology, hwloc_obj_t prev) |
Get the next OS device in the system. More... | |
static __hwloc_inline hwloc_obj_t | hwloc_get_next_bridge (hwloc_topology_t topology, hwloc_obj_t prev) |
Get the next bridge in the system. More... | |
static __hwloc_inline int | hwloc_bridge_covers_pcibus (hwloc_obj_t bridge, unsigned domain, unsigned bus) |
static __hwloc_inline hwloc_obj_t | hwloc_get_hostbridge_by_pcibus (hwloc_topology_t topology, unsigned domain, unsigned bus) |
Find the hostbridge that covers the given PCI bus. More... | |
|
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 |
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
.
