6.2. PCI driversΒΆ
The PCI boards are identified by an identification called PCI ID. The PCI ID is actually composed by two parts:
Vendor ID and device ID;
Subsystem ID and Subsystem device ID;
The lspci -nn
command allows identifying the vendor/device PCI IDs:
$ lspci -nn

The subsystem IDs can be obtained using lspci -vn
$ lspci -vn

00:0a.0 0480: 1131:7133 (rev d1)
Subsystem: 1461:f01d
Flags: bus master, medium devsel, latency 32, IRQ 209
Memory at e2002000 (32-bit, non-prefetchable) [size=2K]
Capabilities: [40] Power Management version 2

At the above example, the first card uses the saa7134
driver, and
has a vendor/device PCI ID equal to 1131:7133
and a PCI subsystem
ID equal to 1461:f01d
(see Saa7134 card list).
Unfortunately, sometimes the same PCI subsystem ID is used by different
products. So, several media drivers allow passing a card=
parameter,
in order to setup a card number that would match the correct settings for
an specific board.
The current supported PCI/PCIe cards (not including staging drivers) are listed below1.
