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

The subsystem IDs can be obtained using ``lspci -vn``
.. code-block:: none

$ lspci -vn

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\ [#]_.
