7
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
84tvaudio.o
85	new, experimental module which is supported to provide a single
86	driver for all simple i2c audio control chips (tda/tea*).
87
88	insmod args:
89		tda8425  = 1	enable/disable the support for the
90		tda9840  = 1	various chips.
91		tda9850  = 1	The tea6300 can't be autodetected and is
92		tda9855  = 1	therefore off by default, if you have
93		tda9873  = 1	this one on your card (STB uses these)
94		tda9874a = 1	you have to enable it explicitly.
95		tea6300  = 0	The two tda985x chips use the same i2c
96		tea6420  = 1	address and can't be disturgished from
97		pic16c54 = 1	each other, you might have to disable
98				the wrong one.
99		debug = 1	print debug messages
100
101	insmod args for tda9874a:
102		tda9874a_SIF=1/2	select sound IF input pin (1 or 2)
103					(default is pin 1)
104		tda9874a_AMSEL=0/1	auto-mute select for NICAM (default=0)
105					Please read note 3 below!
106		tda9874a_STD=n		select TV sound standard (0..8):
107					0 - A2, B/G
108					1 - A2, M (Korea)
109					2 - A2, D/K (1)
110					3 - A2, D/K (2)
111					4 - A2, D/K (3)
112					5 - NICAM, I
113					6 - NICAM, B/G
114					7 - NICAM, D/K (default)
115					8 - NICAM, L
116
117	Note 1: tda9874a supports both tda9874h (old) and tda9874a (new) chips.
118	Note 2: tda9874h/a and tda9875 (which is supported separately by
119	tda9875.o) use the same i2c address so both modules should not be
120	used at the same time.
121	Note 3: Using tda9874a_AMSEL option depends on your TV card design!
122		AMSEL=0: auto-mute will switch between NICAM sound
123			 and the sound on 1st carrier (i.e. FM mono or AM).
124		AMSEL=1: auto-mute will switch between NICAM sound
125			 and the analog mono input (MONOIN pin).
126	If tda9874a decoder on your card has MONOIN pin not connected, then
127	use only tda9874_AMSEL=0 or don't specify this option at all.
128	For example:
129	  card=65 (FlyVideo 2000S) - set AMSEL=1 or AMSEL=0
130	  card=72 (Prolink PV-BT878P rev.9B) - set AMSEL=0 only
131
132msp3400.o
133	The driver for the msp34xx sound processor chips. If you have a
134	stereo card, you probably want to insmod this one.
135
136	insmod args:
137		debug=1/2	print some debug info to the syslog,
138				2 is more verbose.
139		simple=1	Use the "short programming" method.  Newer
140				msp34xx versions support this.  You need this
141				for dbx stereo.  Default is on if supported by
142				the chip.
143		once=1		Don't check the TV-stations Audio mode
144				every few seconds, but only once after
145				channel switches.
146		amsound=1	Audio carrier is AM/NICAM at 6.5 Mhz.  This
147				should improve things for french people, the
148				carrier autoscan seems to work with FM only...
149
150tea6300.o - OBSOLETE (use tvaudio instead)
151	The driver for the tea6300 fader chip.  If you have a stereo
152	card and the msp3400.o doesn't work, you might want to try this
153	one.  This chip is seen on most STB TV/FM cards (usually from
154	Gateway OEM sold surplus on auction sites).
155
156	insmod args:
157		debug=1		print some debug info to the syslog.
158
159tda8425.o - OBSOLETE (use tvaudio instead)
160	The driver for the tda8425 fader chip.  This driver used to be
161	part of bttv.c, so if your sound used to work but does not
162	anymore, try loading this module.
163
164	insmod args:
165		debug=1		print some debug info to the syslog.
166
167tda985x.o - OBSOLETE (use tvaudio instead)
168	The driver for the tda9850/55 audio chips.
169
170	insmod args:
171		debug=1		print some debug info to the syslog.
172		chip=9850/9855	set the chip type.
