5.2. 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:

 $ 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

 $ 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]

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 below[1].
