Field Documentation

unsigned char hwloc_obj_attr_u::hwloc_pcidev_attr_s::bus

Bus number (yy in the PCI BDF notation xxxx:yy:zz.t).

unsigned short hwloc_obj_attr_u::hwloc_pcidev_attr_s::class_id

The class number (first two bytes, without the prog_if).

unsigned char hwloc_obj_attr_u::hwloc_pcidev_attr_s::dev

Device number (zz in the PCI BDF notation xxxx:yy:zz.t).

unsigned short hwloc_obj_attr_u::hwloc_pcidev_attr_s::device_id

Device ID (yyyy in [xxxx:yyyy]).

unsigned short hwloc_obj_attr_u::hwloc_pcidev_attr_s::domain

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

unsigned char hwloc_obj_attr_u::hwloc_pcidev_attr_s::func

Function number (t in the PCI BDF notation xxxx:yy:zz.t).

float hwloc_obj_attr_u::hwloc_pcidev_attr_s::linkspeed

Link speed in GB/s. This datarate is the currently configured speed of the entire PCI link (sum of the bandwidth of all PCI lanes in that link). It may change during execution since some devices are able to slow their PCI links down when idle.
