Linux-2.6.12-rc2v2.6.12-rc2
Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!

+Note: "modinfo <module>" prints various informations 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+This list tends to be outdated because it is updated manually ...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.
+ 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.
+
+ 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).
+
+tvmixer.o
+ registers a mixer device for the TV card's volume/bass/treble
+ controls (requires a i2c audio control chip like the msp3400).
+
+ insmod args:
+ debug=1 print some debug info to the syslog.
+ devnr=n allocate device #n (0 == /dev/mixer,
+ 1 = /dev/mixer1, ...), default is to
+ use the first free one.
+
+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.
