.SS "unsigned char hwloc_obj_attr_u::hwloc_pcidev_attr_s::bus"

.PP
Bus number (yy in the PCI BDF notation xxxx:yy:zz\&.t)\&. 
.SS "unsigned short hwloc_obj_attr_u::hwloc_pcidev_attr_s::class_id"

.PP
The class number (first two bytes, without the prog_if)\&. 
.SS "unsigned char hwloc_obj_attr_u::hwloc_pcidev_attr_s::dev"

.PP
Device number (zz in the PCI BDF notation xxxx:yy:zz\&.t)\&. 
.SS "unsigned short hwloc_obj_attr_u::hwloc_pcidev_attr_s::device_id"

Device ID (yyyy in [xxxx:yyyy])\&. 
.SS "unsigned short hwloc_obj_attr_u::hwloc_pcidev_attr_s::domain"

.PP
Domain number (xxxx in the PCI BDF notation xxxx:yy:zz\&.t)\&. Only 16bits PCI domains are supported by default\&.
