devfunc Number, Adapter Number or Physical Location
Bus Type or PCI Parent Bus
Ÿ
The AB value identifies a bus type or PCI parent bus as assigned by the
firmware.
Ÿ
The CD value identifies adapter number, adapter's devfunc number, or physical
location. The devfunc number is defined as the PCI device number times 8, plus
the function number.
Ÿ
The EF value identifies a connector.
Ÿ
The GH value identifies a port, address, device, or FRU.
Adapters and cards are identified with just AB-CD.
The possible values for AB are:
The possible values for CD depend on the adapter/card.
For pluggable PCI adapters/cards, CD is the device's devfunc number (PCI device
number times 8, plus the function number). The C and D are characters in the range
of 0-9, and A-F (hex numbers). This allows the location code to uniquely identify
multiple adapters on individual PCI cards.
For pluggable ISA adapters, CD is equal to the order the ISA cards
defined/configured either by SMIT or the ISA Adapter Configuration Service Aid.
For integrated ISA adapters, CD is equal to a unique code identifying the ISA
adapter. In most cases this is equal to the adapter's physical location code. In cases
where a physical location code is not available, CD will be FF.
EF is the connector ID. It is used to identify the adapter's connector that a resource
is attached to.
00 Processor bus
01 ISA bus
02 EISA bus
03 MCA bus
04 PCI bus used in the case where the PCI bus cannot be identified
05 PCMCIA buses
xy For PCI adapters where x is equal to or greater than 1. The x and y are characters in the
range of 0-9, A-H, J-N, P-Z (O, I, and lower case are omitted) and are equal to the parent
bus's ibm, aix-loc Open Firmware Property.
