| 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| This list tends to be outdated because it is updated manually ...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. |
| 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). |
| |
| 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. |
