The database is generated from CARDLIST.saa7134 and CARDLIST.bttv file for
respective drivers. I just have found that there is also CARDLIST.cx88 file. But
for which driver it is?

kernel/drivers/media/video/cx88 contains these drivers:
cx88-blackbird.ko
cx88-dvb.ko
cx88xx.ko
cx8800.ko
cx8802.ko

To which driver is the file related? cx88xx? (The most generic name?) 

The database was updated in yast2-tv-2.12.5 (bttv and saa7134 driver options,
the database generator now also better groups cards by vendor).

CARDLIST.cx88 is still not used, waiting for info.

It's not that easy with cx88, The chip has several pci functions which can be
enabled and disabled.

PCI function 0 (pci ID 0x8800) is analog tv/video, the driver module for that
one is cx8800.

PCI function 2 (pci id 0x8802) is for MPEG transport stream transfer, on
existing cards this is used for both analog cards with hardware mpeg encoder
(cx88-blackbird) and dvb cards (cx88-dvb).  You have to itentify the card by
subsystem ID to figure which is dvb and wich is blackbird, the driver has that
informations in the card database (cx88-cards.c).

cx88xx.ko is common core core, cx8802.ko is common code for the blackbird and
dvb drivers, both are autoloaded by symbol references so yast2/hwinfo doesn't
need to know about them.

Thanks for the info!

I suppose that CARDLIST.cx88 has similar syntax to CARDLIST.bttv.
In that case it would mean that CARDLIST.cx88 contains possible values for
module option card.

As I can see the only driver from the list in comment #1 which has card option
is cx88xx.

For CARDLIST.bttv cards yast uses bttv driver with option card=X, would that
work for cx88xx driver as well? It seems that I need to use also another module
(cx88-blackbird or cx88-dvb), right? It would be too compilated in that case...

Yes, CARDLIST.cx88 is simliar and it is the cx88xx core module which takes the
card= insmod option.  The other driver modules get the info indirectly from
cx88xx and don't need any insmod options.

back to ladislav (comment #5 hopefully answers your question).

OK, if I understand it correctly the yast module should set cx88xx driver for
the cards mentioned in CARDLIST.cx88, right?

Fixed in STABLE (yast2-tv-2.13.0)

Yes, "options cx88xx card=..."
