2 Note: "modinfo <module>" prints various informations about a kernel
3 module, among them a complete and up-to-date list of insmod options.
4 This list tends to be outdated because it is updated manually ...
6 ==========================================================================
9 the bt848/878 (grabber chip) driver
12 card=n card type, see CARDLIST for a list.
13 tuner=n tuner type, see CARDLIST for a list.
14 radio=0/1 card supports radio
15 pll=0/1/2 pll settings
17 1: 28 MHz crystal installed
18 2: 35 MHz crystal installed
20 triton1=0/1 for Triton1 (+others) compatibility
21 vsfx=0/1 yet another chipset bug compatibility bit
22 see README.quirks for details on these two.
24 bigendian=n Set the endianness of the gfx framebuffer.
25 Default is native endian.
26 fieldnr=0/1 Count fields. Some TV descrambling software
27 needs this, for others it only generates
28 50 useless IRQs/sec. default is 0 (off).
29 autoload=0/1 autoload helper modules (tuner, audio).
31 bttv_verbose=0/1/2 verbose level (at insmod time, while
32 looking at the hardware). default is 1.
33 bttv_debug=0/1 debug messages (for capture).
35 irq_debug=0/1 irq handler debug messages.
37 gbuffers=2-32 number of capture buffers for mmap'ed capture.
39 gbufsize= size of capture buffers. default and
40 maximum value is 0x208000 (~2MB)
41 no_overlay=0 Enable overlay on broken hardware. There
42 are some chipsets (SIS for example) which
43 are known to have problems with the PCI DMA
44 push used by bttv. bttv will disable overlay
45 by default on this hardware to avoid crashes.
46 With this insmod option you can override this.
47 no_overlay=1 Disable overlay. It should be used by broken
48 hardware that doesn't support PCI2PCI direct
50 automute=0/1 Automatically mutes the sound if there is
51 no TV signal, on by default. You might try
52 to disable this if you have bad input signal
53 quality which leading to unwanted sound
55 chroma_agc=0/1 AGC of chroma signal, off by default.
56 adc_crush=0/1 Luminance ADC crush, on by default.
62 See Sound-FAQ for a detailed description.
64 remap, card, radio and pll accept up to four comma-separated arguments
65 (for multiple boards).
68 The tuner driver. You need this unless you want to use only
69 with a camera or external tuner ...
72 debug=1 print some debug info to the syslog
73 type=n type of the tuner chip. n as follows:
74 see CARDLIST for a complete list.
75 pal=[bdgil] select PAL variant (used for some tuners
76 only, important for the audio carrier).
79 registers a mixer device for the TV card's volume/bass/treble
80 controls (requires a i2c audio control chip like the msp3400).
83 debug=1 print some debug info to the syslog.
84 devnr=n allocate device #n (0 == /dev/mixer,
85 1 = /dev/mixer1, ...), default is to
86 use the first free one.
89 new, experimental module which is supported to provide a single
90 driver for all simple i2c audio control chips (tda/tea*).
93 tda8425 = 1 enable/disable the support for the
94 tda9840 = 1 various chips.
95 tda9850 = 1 The tea6300 can't be autodetected and is
96 tda9855 = 1 therefore off by default, if you have
97 tda9873 = 1 this one on your card (STB uses these)
98 tda9874a = 1 you have to enable it explicitly.
99 tea6300 = 0 The two tda985x chips use the same i2c
100 tea6420 = 1 address and can't be disturgished from
101 pic16c54 = 1 each other, you might have to disable
103 debug = 1 print debug messages
105 insmod args for tda9874a:
106 tda9874a_SIF=1/2 select sound IF input pin (1 or 2)
108 tda9874a_AMSEL=0/1 auto-mute select for NICAM (default=0)
109 Please read note 3 below!
110 tda9874a_STD=n select TV sound standard (0..8):
118 7 - NICAM, D/K (default)
121 Note 1: tda9874a supports both tda9874h (old) and tda9874a (new) chips.
122 Note 2: tda9874h/a and tda9875 (which is supported separately by
123 tda9875.o) use the same i2c address so both modules should not be
124 used at the same time.
125 Note 3: Using tda9874a_AMSEL option depends on your TV card design!
126 AMSEL=0: auto-mute will switch between NICAM sound
127 and the sound on 1st carrier (i.e. FM mono or AM).
128 AMSEL=1: auto-mute will switch between NICAM sound
129 and the analog mono input (MONOIN pin).
130 If tda9874a decoder on your card has MONOIN pin not connected, then
131 use only tda9874_AMSEL=0 or don't specify this option at all.
133 card=65 (FlyVideo 2000S) - set AMSEL=1 or AMSEL=0
134 card=72 (Prolink PV-BT878P rev.9B) - set AMSEL=0 only
137 The driver for the msp34xx sound processor chips. If you have a
138 stereo card, you probably want to insmod this one.
141 debug=1/2 print some debug info to the syslog,
143 simple=1 Use the "short programming" method. Newer
144 msp34xx versions support this. You need this
145 for dbx stereo. Default is on if supported by
147 once=1 Don't check the TV-stations Audio mode
148 every few seconds, but only once after
150 amsound=1 Audio carrier is AM/NICAM at 6.5 Mhz. This
151 should improve things for french people, the
152 carrier autoscan seems to work with FM only...
154 tea6300.o - OBSOLETE (use tvaudio instead)
155 The driver for the tea6300 fader chip. If you have a stereo
156 card and the msp3400.o doesn't work, you might want to try this
157 one. This chip is seen on most STB TV/FM cards (usually from
158 Gateway OEM sold surplus on auction sites).
161 debug=1 print some debug info to the syslog.
163 tda8425.o - OBSOLETE (use tvaudio instead)
164 The driver for the tda8425 fader chip. This driver used to be
165 part of bttv.c, so if your sound used to work but does not
166 anymore, try loading this module.
169 debug=1 print some debug info to the syslog.
171 tda985x.o - OBSOLETE (use tvaudio instead)
172 The driver for the tda9850/55 audio chips.
175 debug=1 print some debug info to the syslog.
176 chip=9850/9855 set the chip type.
