8bttv.o
9 the bt848/878 (grabber chip) driver
10
11 insmod args:
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
16 0: don't use PLL
17 1: 28 MHz crystal installed
18 2: 35 MHz crystal installed
19
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.
23
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).
30 default is 1 (on).
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).
34 default is 0 (off).
35 irq_debug=0/1 irq handler debug messages.
36 default is 0 (off).
37 gbuffers=2-32 number of capture buffers for mmap'ed capture.
38 default is 4.
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
49 transfers.
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
54 dropouts.
55 chroma_agc=0/1 AGC of chroma signal, off by default.
56 adc_crush=0/1 Luminance ADC crush, on by default.
57 i2c_udelay= Allow reduce I2C speed. Default is 5 usecs
58 (meaning 66,67 Kbps). The default is the
59 maximum supported speed by kernel bitbang
60 algorithm. You may use lower numbers, if I2C
61 messages are lost (16 is known to work on
62 all supported cards).
63
64 bttv_gpio=0/1
65 gpiomask=
66 audioall=
67 audiomux=
68 See Sound-FAQ for a detailed description.
69
70 remap, card, radio and pll accept up to four comma-separated arguments
71 (for multiple boards).
72
73tuner.o
74 The tuner driver. You need this unless you want to use only
75 with a camera or external tuner ...
76
77 insmod args:
78 debug=1 print some debug info to the syslog
79 type=n type of the tuner chip. n as follows:
80 see CARDLIST for a complete list.
81 pal=[bdgil] select PAL variant (used for some tuners
82 only, important for the audio carrier).
83
84tvmixer.o
85 registers a mixer device for the TV card's volume/bass/treble
86 controls (requires a i2c audio control chip like the msp3400).
87
88 insmod args:
89 debug=1 print some debug info to the syslog.
90 devnr=n allocate device #n (0 == /dev/mixer,
91 1 = /dev/mixer1, ...), default is to
92 use the first free one.
93
94tvaudio.o
95 new, experimental module which is supported to provide a single
96 driver for all simple i2c audio control chips (tda/tea*).
97
98 insmod args:
99 tda8425 = 1 enable/disable the support for the
100 tda9840 = 1 various chips.
101 tda9850 = 1 The tea6300 can't be autodetected and is
102 tda9855 = 1 therefore off by default, if you have
103 tda9873 = 1 this one on your card (STB uses these)
104 tda9874a = 1 you have to enable it explicitly.
105 tea6300 = 0 The two tda985x chips use the same i2c
106 tea6420 = 1 address and can't be disturgished from
107 pic16c54 = 1 each other, you might have to disable
108 the wrong one.
109 debug = 1 print debug messages
110
111 insmod args for tda9874a:
112 tda9874a_SIF=1/2 select sound IF input pin (1 or 2)
113 (default is pin 1)
114 tda9874a_AMSEL=0/1 auto-mute select for NICAM (default=0)
115 Please read note 3 below!
116 tda9874a_STD=n select TV sound standard (0..8):
117 0 - A2, B/G
118 1 - A2, M (Korea)
119 2 - A2, D/K (1)
120 3 - A2, D/K (2)
121 4 - A2, D/K (3)
122 5 - NICAM, I
123 6 - NICAM, B/G
124 7 - NICAM, D/K (default)
125 8 - NICAM, L
126
127 Note 1: tda9874a supports both tda9874h (old) and tda9874a (new) chips.
128 Note 2: tda9874h/a and tda9875 (which is supported separately by
129 tda9875.o) use the same i2c address so both modules should not be
130 used at the same time.
131 Note 3: Using tda9874a_AMSEL option depends on your TV card design!
132 AMSEL=0: auto-mute will switch between NICAM sound
133 and the sound on 1st carrier (i.e. FM mono or AM).
134 AMSEL=1: auto-mute will switch between NICAM sound
135 and the analog mono input (MONOIN pin).
136 If tda9874a decoder on your card has MONOIN pin not connected, then
137 use only tda9874_AMSEL=0 or don't specify this option at all.
138 For example:
139 card=65 (FlyVideo 2000S) - set AMSEL=1 or AMSEL=0
140 card=72 (Prolink PV-BT878P rev.9B) - set AMSEL=0 only
141
142msp3400.o
143 The driver for the msp34xx sound processor chips. If you have a
144 stereo card, you probably want to insmod this one.
145
146 insmod args:
147 debug=1/2 print some debug info to the syslog,
148 2 is more verbose.
149 simple=1 Use the "short programming" method. Newer
150 msp34xx versions support this. You need this
151 for dbx stereo. Default is on if supported by
152 the chip.
153 once=1 Don't check the TV-stations Audio mode
154 every few seconds, but only once after
155 channel switches.
156 amsound=1 Audio carrier is AM/NICAM at 6.5 Mhz. This
157 should improve things for french people, the
158 carrier autoscan seems to work with FM only...
159
160tea6300.o - OBSOLETE (use tvaudio instead)
161 The driver for the tea6300 fader chip. If you have a stereo
162 card and the msp3400.o doesn't work, you might want to try this
163 one. This chip is seen on most STB TV/FM cards (usually from
164 Gateway OEM sold surplus on auction sites).
165
166 insmod args:
167 debug=1 print some debug info to the syslog.
168
169tda8425.o - OBSOLETE (use tvaudio instead)
170 The driver for the tda8425 fader chip. This driver used to be
171 part of bttv.c, so if your sound used to work but does not
172 anymore, try loading this module.
173
174 insmod args:
175 debug=1 print some debug info to the syslog.
176
177tda985x.o - OBSOLETE (use tvaudio instead)
178 The driver for the tda9850/55 audio chips.
179
180 insmod args:
181 debug=1 print some debug info to the syslog.
182 chip=9850/9855 set the chip type.
