0018 As with bttv, card-specific tweaks are needed. Check CARDLIST for a
0019 list of known TV cards and saa7134-cards.c for the drivers card

0026 Once you pick up a Kernel source, you should configure, build,
0027 install and boot the new kernel. You'll need at least
0028 these config options::
0029
0030 ./scripts/config -e PCI
0031 ./scripts/config -e INPUT
0032 ./scripts/config -m I2C
0033 ./scripts/config -m MEDIA_SUPPORT
0034 ./scripts/config -e MEDIA_PCI_SUPPORT
0035 ./scripts/config -e MEDIA_ANALOG_TV_SUPPORT
0036 ./scripts/config -e MEDIA_DIGITAL_TV_SUPPORT
0037 ./scripts/config -e MEDIA_RADIO_SUPPORT
0038 ./scripts/config -e RC_CORE
0039 ./scripts/config -e MEDIA_SUBDRV_AUTOSELECT
0040 ./scripts/config -m VIDEO_SAA7134
0041 ./scripts/config -e SAA7134_ALSA
0042 ./scripts/config -e VIDEO_SAA7134_RC
0043 ./scripts/config -e VIDEO_SAA7134_DVB
0044 ./scripts/config -e VIDEO_SAA7134_GO7007
0045
0046 To build and install, you should run::
0047
0048 make && make modules_install && make install
0049
0050 Once the new Kernel is booted, saa7134 driver should be loaded automatically.
0051
0052 Depending on the card you might have to pass ``card=<nr>`` as insmod option.
0053 If so, please check Documentation/admin-guide/media/saa7134-cardlist.rst
0054 for valid choices.
0055
0056 Once you have your card type number, you can pass a modules configuration
0057 via a file (usually, it is either ``/etc/modules.conf`` or some file at
0058 ``/etc/modules-load.d/``, but the actual place depends on your
0059 distribution), with this content::
0060
0061 options saa7134 card=13 # Assuming that your card type is #13

0078 Known Problems
0079 --------------
0080
0081 * The tuner for the flyvideos isn't detected automatically and the
0082 default might not work for you depending on which version you have.
0083 There is a ``tuner=`` insmod option to override the driver's default.
