.. SPDX-License-Identifier: GPL-2.0 The cx88 driver =============== Author: Gerd Hoffmann This is a v4l2 device driver for the cx2388x chip. Current status -------------- video - Works. - Overlay isn't supported. audio - Works. The TV standard detection is made by the driver, as the hardware has bugs to auto-detect. - audio data dma (i.e. recording without loopback cable to the sound card) is supported via cx88-alsa. vbi - Works. How to add support for new cards -------------------------------- The driver needs some config info for the TV cards. This stuff is in cx88-cards.c. If the driver doesn't work well you likely need a new entry for your card in that file. Check the kernel log (using dmesg) to see whenever the driver knows your card or not. There is a line like this one: .. code-block:: none cx8800[0]: subsystem: 0070:3400, board: Hauppauge WinTV \ 34xxx models [card=1,autodetected] If your card is listed as "board: UNKNOWN/GENERIC" it is unknown to the driver. What to do then? 1) Try upgrading to the latest snapshot, maybe it has been added meanwhile. 2) You can try to create a new entry yourself, have a look at cx88-cards.c. If that worked, mail me your changes as unified diff ("diff -u"). 3) Or you can mail me the config information. We need at least the following information to add the card: - the PCI Subsystem ID ("0070:3400" from the line above, "lspci -v" output is fine too). - the tuner type used by the card. You can try to find one by trial-and-error using the tuner= insmod option. If you know which one the card has you can also have a look at the list in CARDLIST.tuner
