PCI drivers
===========

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:

.. code-block:: none
   :emphasize-lines: 3

    $ lspci -nn
    ...
    00:0a.0 Multimedia controller [0480]: Philips Semiconductors SAA7131/SAA7133/SAA7135 Video Broadcast Decoder [1131:7133] (rev d1)
    00:0b.0 Multimedia controller [0480]: Brooktree Corporation Bt878 Audio Capture [109e:0878] (rev 11)
    01:00.0 Multimedia video controller [0400]: Conexant Systems, Inc. CX23887/8 PCIe Broadcast Audio and Video Decoder with 3D Comb [14f1:8880] (rev 0f)
    02:01.0 Multimedia video controller [0400]: Internext Compression Inc iTVC15 (CX23415) Video Decoder [4444:0803] (rev 01)
    02:02.0 Multimedia video controller [0400]: Conexant Systems, Inc. CX23418 Single-Chip MPEG-2 Encoder with Integrated Analog Video/Broadcast Audio Decoder [14f1:5b7a]
    02:03.0 Multimedia video controller [0400]: Brooktree Corporation Bt878 Video Capture [109e:036e] (rev 11)
    ...

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

.. code-block:: none
   :emphasize-lines: 4

    $ 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 :doc:`Saa7134 card list<saa7134-cardlist>`).

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 below\ [#]_.
