.SS "int hwloc_insert_pci_device_list (struct \fBhwloc_backend\fP *backend, struct \fBhwloc_obj\fP *first_obj)"
.PP
Insert a list of PCI devices and bridges in the backend topology\&. Insert a list of objects (either PCI device or bridges) starting at first_obj (linked by next_sibling in the topology, and ending with NULL)\&. Objects are placed under the right bridges, and the remaining upstream bridges are then inserted in the topology by calling the get_obj_cpuset() callback to find their locality\&.
.SS "unsigned hwloc_pci_find_cap (const unsigned char *config, unsignedcap)"
.PP
Return the offset of the given capability in the PCI config space buffer\&. This function requires a 256-bytes config space\&. Unknown/unavailable bytes should be set to 0xff\&.
.SS "int hwloc_pci_find_linkspeed (const unsigned char *config, unsignedoffset, float *linkspeed)"
.PP
Fill linkspeed by reading the PCI config space where PCI_CAP_ID_EXP is at position offset\&. Needs 20 bytes of EXP capability block starting at offset in the config space for registers up to link status\&.
.SS "int hwloc_pci_prepare_bridge (\fBhwloc_obj_t\fPobj, const unsigned char *config)"
.PP
Modify the PCI device object into a bridge and fill its attribute if a bridge is found in the PCI config space\&. This function requires 64 bytes of common configuration header at the beginning of config\&.
