| 16 | Almost everything is working. video, sound, tuner, radio, mpeg ts, ... | |
| 17 | ||
| 18 | As with bttv, card-specific tweaks are needed. Check CARDLIST for a | |
| 19 | list of known TV cards and saa7134-cards.c for the drivers card | |
| 20 | configuration info. | |

26 | Once you pick up a Kernel source, you should configure, build, |
| 27 | install and boot the new kernel. You'll need at least | |
| 28 | these config options:: | |
| 1da177e4 | 29 | |
| 12bcf90c MCC |
30 | ./scripts/config -e PCI |
| 31 | ./scripts/config -e INPUT | |
| 32 | ./scripts/config -m I2C | |
| 33 | ./scripts/config -m MEDIA_SUPPORT | |
| 34 | ./scripts/config -e MEDIA_PCI_SUPPORT | |
| 35 | ./scripts/config -e MEDIA_ANALOG_TV_SUPPORT | |
| 36 | ./scripts/config -e MEDIA_DIGITAL_TV_SUPPORT | |
| 37 | ./scripts/config -e MEDIA_RADIO_SUPPORT | |
| 38 | ./scripts/config -e RC_CORE | |
| 39 | ./scripts/config -e MEDIA_SUBDRV_AUTOSELECT | |
| 40 | ./scripts/config -m VIDEO_SAA7134 | |
| 41 | ./scripts/config -e SAA7134_ALSA | |
| 42 | ./scripts/config -e VIDEO_SAA7134_RC | |
| 43 | ./scripts/config -e VIDEO_SAA7134_DVB | |
| 44 | ./scripts/config -e VIDEO_SAA7134_GO7007 | |
| ae9d2873 | 45 | |
| 12bcf90c | 46 | To build and install, you should run:: |
| 1da177e4 | 47 | |
| 12bcf90c MCC |
48 | make && make modules_install && make install |
| 49 | ||
| 50 | Once the new Kernel is booted, saa7134 driver should be loaded automatically. | |
| 51 | ||
| 52 | Depending on the card you might have to pass ``card=<nr>`` as insmod option. | |
| 53 | If so, please check :doc:`saa7134-cardlist` for valid choices. | |
| 54 | ||
| 55 | Once you have your card type number, you can pass a modules configuration | |
| 56 | via a file (usually, it is either ``/etc/modules.conf`` or some file at | |
| 57 | ``/etc/modules-load.d/``, but the actual place depends on your | |
| 58 | distribution), with this content:: | |
| 59 | ||
| 60 | options saa7134 card=13 # Assuming that your card type is #13 | |

79 | |
| 80 | * The tuner for the flyvideos isn't detected automatically and the | |
| 81 | default might not work for you depending on which version you have. | |
| 12bcf90c | 82 | There is a ``tuner=`` insmod option to override the driver's default. |
