Hello,
hwloc_topology_init(&topology);
hwloc_topology_set_flags(topology, HWLOC_TOPOLOGY_FLAG_IO_DEVICES);
hwloc_topology_load(topology);
Then you can use hwloc_get_next_pcidev() to iterate over the entire list
PCI devices. If you want to know whether it's connected to a specific
NUMA node, start from the PCI hwloc_obj_t and walk up the ->parent
pointer until you find a NUMA node object (not guaranteed, could be
connected to something else, even something that is not a child of a
NUMA node, for instance the entire machine object).
Otherwise, you can start at the NUMA node object, walk its children
until you find some object of type Bridge, then recursively walk
children to find all PCI objects (it's often organized as a imbalanced
tree, there can other bridges in the middle).
