| 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 |

| |
| $ lspci -nn |

| The subsystem IDs can be obtained using ``lspci -vn`` |
| |
| .. code-block:: none |
| :emphasize-lines: 4 |
| |
| $ 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 |
