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:

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.

||
|
|
