Note: "modinfo <module>" prints various information about a kernel
module, among them a complete and up-to-date list of insmod options.
This list tends to be outdated because it is updated manually ...
==========================================================================
bttv.o
the bt848/878 (grabber chip) driver
insmod args:
card=n card type, see CARDLIST for a list.
tuner=n tuner type, see CARDLIST for a list.
radio=0/1 card supports radio
pll=0/1/2 pll settings
0: don't use PLL
1: 28 MHz crystal installed
2: 35 MHz crystal installed
triton1=0/1 for Triton1 (+others) compatibility
vsfx=0/1 yet another chipset bug compatibility bit
see README.quirks for details on these two.
bigendian=n Set the endianness of the gfx framebuffer.
Default is native endian.
fieldnr=0/1 Count fields. Some TV descrambling software
needs this, for others it only generates
50 useless IRQs/sec. default is 0 (off).
autoload=0/1 autoload helper modules (tuner, audio).
default is 1 (on).
bttv_verbose=0/1/2 verbose level (at insmod time, while
looking at the hardware). default is 1.
bttv_debug=0/1 debug messages (for capture).
default is 0 (off).
irq_debug=0/1 irq handler debug messages.
default is 0 (off).
gbuffers=2-32 number of capture buffers for mmap'ed capture.
default is 4.
gbufsize= size of capture buffers. default and
maximum value is 0x208000 (~2MB)
no_overlay=0 Enable overlay on broken hardware. There
are some chipsets (SIS for example) which
are known to have problems with the PCI DMA
push used by bttv. bttv will disable overlay
by default on this hardware to avoid crashes.
With this insmod option you can override this.
no_overlay=1 Disable overlay. It should be used by broken
hardware that doesn't support PCI2PCI direct
transfers.
automute=0/1 Automatically mutes the sound if there is
no TV signal, on by default. You might try
to disable this if you have bad input signal
quality which leading to unwanted sound
dropouts.
chroma_agc=0/1 AGC of chroma signal, off by default.
adc_crush=0/1 Luminance ADC crush, on by default.
i2c_udelay= Allow reduce I2C speed. Default is 5 usecs
(meaning 66,67 Kbps). The default is the
maximum supported speed by kernel bitbang
algorithm. You may use lower numbers, if I2C
messages are lost (16 is known to work on
all supported cards).
bttv_gpio=0/1
gpiomask=
audioall=
audiomux=
See Sound-FAQ for a detailed description.
remap, card, radio and pll accept up to four comma-separated arguments
(for multiple boards).
tuner.o
The tuner driver. You need this unless you want to use only
with a camera or external tuner ...
insmod args:
debug=1 print some debug info to the syslog
type=n type of the tuner chip. n as follows:
see CARDLIST for a complete list.
pal=[bdgil] select PAL variant (used for some tuners
only, important for the audio carrier).
tvaudio.o
new, experimental module which is supported to provide a single
driver for all simple i2c audio control chips (tda/tea*).
insmod args:
tda8425 = 1 enable/disable the support for the
tda9840 = 1 various chips.
tda9850 = 1 The tea6300 can't be autodetected and is
tda9855 = 1 therefore off by default, if you have
tda9873 = 1 this one on your card (STB uses these)
tda9874a = 1 you have to enable it explicitly.
tea6300 = 0 The two tda985x chips use the same i2c
tea6420 = 1 address and can't be disturgished from
pic16c54 = 1 each other, you might have to disable
the wrong one.
debug = 1 print debug messages
insmod args for tda9874a:
tda9874a_SIF=1/2 select sound IF input pin (1 or 2)
(default is pin 1)
tda9874a_AMSEL=0/1 auto-mute select for NICAM (default=0)
Please read note 3 below!
tda9874a_STD=n select TV sound standard (0..8):
0 - A2, B/G
1 - A2, M (Korea)
2 - A2, D/K (1)
3 - A2, D/K (2)
4 - A2, D/K (3)
5 - NICAM, I
6 - NICAM, B/G
7 - NICAM, D/K (default)
8 - NICAM, L
Note 1: tda9874a supports both tda9874h (old) and tda9874a (new) chips.
Note 2: tda9874h/a and tda9875 (which is supported separately by
tda9875.o) use the same i2c address so both modules should not be
used at the same time.
Note 3: Using tda9874a_AMSEL option depends on your TV card design!
AMSEL=0: auto-mute will switch between NICAM sound
and the sound on 1st carrier (i.e. FM mono or AM).
AMSEL=1: auto-mute will switch between NICAM sound
and the analog mono input (MONOIN pin).
If tda9874a decoder on your card has MONOIN pin not connected, then
use only tda9874_AMSEL=0 or don't specify this option at all.
For example:
card=65 (FlyVideo 2000S) - set AMSEL=1 or AMSEL=0
card=72 (Prolink PV-BT878P rev.9B) - set AMSEL=0 only
msp3400.o
The driver for the msp34xx sound processor chips. If you have a
stereo card, you probably want to insmod this one.
insmod args:
debug=1/2 print some debug info to the syslog,
2 is more verbose.
simple=1 Use the "short programming" method. Newer
msp34xx versions support this. You need this
for dbx stereo. Default is on if supported by
the chip.
once=1 Don't check the TV-stations Audio mode
every few seconds, but only once after
channel switches.
amsound=1 Audio carrier is AM/NICAM at 6.5 Mhz. This
should improve things for french people, the
carrier autoscan seems to work with FM only...
tea6300.o - OBSOLETE (use tvaudio instead)
The driver for the tea6300 fader chip. If you have a stereo
card and the msp3400.o doesn't work, you might want to try this
one. This chip is seen on most STB TV/FM cards (usually from
Gateway OEM sold surplus on auction sites).
insmod args:
debug=1 print some debug info to the syslog.
tda8425.o - OBSOLETE (use tvaudio instead)
The driver for the tda8425 fader chip. This driver used to be
part of bttv.c, so if your sound used to work but does not
anymore, try loading this module.
insmod args:
debug=1 print some debug info to the syslog.
tda985x.o - OBSOLETE (use tvaudio instead)
The driver for the tda9850/55 audio chips.
insmod args:
debug=1 print some debug info to the syslog.
chip=9850/9855 set the chip type.
