7.1. The bttv driver

7.1.1. Release notes for bttv

You’ll need at least these config options for bttv:

./scripts/config -e PCI
./scripts/config -m I2C
./scripts/config -m INPUT
./scripts/config -m MEDIA_SUPPORT
./scripts/config -e MEDIA_PCI_SUPPORT
./scripts/config -e MEDIA_ANALOG_TV_SUPPORT
./scripts/config -e MEDIA_DIGITAL_TV_SUPPORT
./scripts/config -e MEDIA_RADIO_SUPPORT
./scripts/config -e RC_CORE
./scripts/config -m VIDEO_BT848

If your board has digital TV, you’ll also need:

./scripts/config -m DVB_BT8XX

In this case, please see How to get the bt8xx cards working for additional notes.

7.1.2. Make bttv work with your card

If you have bttv compiled and installed, just booting the Kernel should be enough for it to try probing it. However, depending on the model, the Kernel may require additional information about the hardware, as the device may not be able to provide such info directly to the Kernel.

If it doesn’t bttv likely could not autodetect your card and needs some insmod options. The most important insmod option for bttv is “card=n” to select the correct card type. If you get video but no sound you’ve very likely specified the wrong (or no) card type. A list of supported cards is in BTTV cards list.

If bttv takes very long to load (happens sometimes with the cheap cards which have no tuner), try adding this to your modules configuration file (usually, it is either /etc/modules.conf or some file at /etc/modules-load.d/, but the actual place depends on your distribution):

options i2c-algo-bit bit_test=1

Some cards may require an extra firmware file to work. For example, for the WinTV/PVR you need one firmware file from its driver CD, called: hcwamc.rbf. It is inside a self-extracting zip file called pvr45xxx.exe. Just placing it at the /etc/firmware directory should be enough for it to be autoload during the driver’s probing mode (e. g. when the Kernel boots or when the driver is manually loaded via modprobe command).

If your card isn’t listed in BTTV cards list or if you have trouble making audio work, please read Still doesn’t work?.

7.1.3. Autodetecting cards

bttv uses the PCI Subsystem ID to autodetect the card type. lspci lists the Subsystem ID in the second line, looks like this:

00:0a.0 Multimedia video controller: Brooktree Corporation Bt878 (rev 02)
        Subsystem: Hauppauge computer works Inc. WinTV/GO
        Flags: bus master, medium devsel, latency 32, IRQ 5
        Memory at e2000000 (32-bit, prefetchable) [size=4K]

only bt878-based cards can have a subsystem ID (which does not mean that every card really has one). bt848 cards can’t have a Subsystem ID and therefore can’t be autodetected. There is a list with the ID’s at BTTV cards list (in case you are interested or want to mail patches with updates).

7.1.4. Still doesn’t work?

I do NOT have a lab with 30+ different grabber boards and a PAL/NTSC/SECAM test signal generator at home, so I often can’t reproduce your problems. This makes debugging very difficult for me.

If you have some knowledge and spare time, please try to fix this yourself (patches very welcome of course...) You know: The linux slogan is “Do it yourself”.

There is a mailing list at http://vger.kernel.org/vger-lists.html#linux-media

If you have trouble with some specific TV card, try to ask there instead of mailing me directly. The chance that someone with the same card listens there is much higher...

For problems with sound: There are a lot of different systems used for TV sound all over the world. And there are also different chips which decode the audio signal. Reports about sound problems (“stereo doesn’t work”) are pretty useless unless you include some details about your hardware and the TV sound scheme used in your country (or at least the country you are living in).

7.1.5. Modprobe options


The following argument list can be outdated, as we might add more options if ever needed. In case of doubt, please check with modinfo <module>.

This command prints various information about a kernel module, among them a complete and up-to-date list of insmod options.


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
    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
    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).

                    See Sound-FAQ for a detailed description.

remap, card, radio and pll accept up to four comma-separated arguments
(for multiple boards).

The tuner driver. You need this unless you want to use only with a camera or the board doesn’t provide analog TV tuning.

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).

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

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...

7.1.6. If the box freezes hard with bttv

It might be a bttv driver bug. It also might be bad hardware. It also might be something else ...

Just mailing me “bttv freezes” isn’t going to help much. This README has a few hints how you can help to pin down the problem. bttv bugs

If some version works and another doesn’t it is likely to be a driver bug. It is very helpful if you can tell where exactly it broke (i.e. the last working and the first broken version).

With a hard freeze you probably doesn’t find anything in the logfiles. The only way to capture any kernel messages is to hook up a serial console and let some terminal application log the messages. /me uses screen. See Linux Serial Console for details on setting up a serial console.

Read Bug hunting to learn how to get any useful information out of a register+stack dump printed by the kernel on protection faults (so-called “kernel oops”).

If you run into some kind of deadlock, you can try to dump a call trace for each process using sysrq-t (see Linux Magic System Request Key Hacks). This way it is possible to figure where exactly some process in “D” state is stuck.

I’ve seen reports that bttv 0.7.x crashes whereas 0.8.x works rock solid for some people. Thus probably a small buglet left somewhere in bttv 0.7.x. I have no idea where exactly, it works stable for me and a lot of other people. But in case you have problems with the 0.7.x versions you can give 0.8.x a try ... hardware bugs

Some hardware can’t deal with PCI-PCI transfers (i.e. grabber => vga). Sometimes problems show up with bttv just because of the high load on the PCI bus. The bt848/878 chips have a few workarounds for known incompatibilities, see README.quirks.

Some folks report that increasing the pci latency helps too, althrought I’m not sure whenever this really fixes the problems or only makes it less likely to happen. Both bttv and btaudio have a insmod option to set the PCI latency of the device.

Some mainboard have problems to deal correctly with multiple devices doing DMA at the same time. bttv + ide seems to cause this sometimes, if this is the case you likely see freezes only with video and hard disk access at the same time. Updating the IDE driver to get the latest and greatest workarounds for hardware bugs might fix these problems. other

If you use some binary-only yunk (like nvidia module) try to reproduce the problem without.

IRQ sharing is known to cause problems in some cases. It works just fine in theory and many configurations. Neverless it might be worth a try to shuffle around the PCI cards to give bttv another IRQ or make it share the IRQ with some other piece of hardware. IRQ sharing with VGA cards seems to cause trouble sometimes. I’ve also seen funny effects with bttv sharing the IRQ with the ACPI bridge (and apci-enabled kernel).

7.1.7. Bttv quirks

Below is what the bt878 data book says about the PCI bug compatibility modes of the bt878 chip.

The triton1 insmod option sets the EN_TBFX bit in the control register. The vsfx insmod option does the same for EN_VSFX bit. If you have stability problems you can try if one of these options makes your box work solid.

drivers/pci/quirks.c knows about these issues, this way these bits are enabled automagically for known-buggy chipsets (look at the kernel messages, bttv tells you). Normal PCI Mode

The PCI REQ signal is the logical-or of the incoming function requests. The inter-nal GNT[0:1] signals are gated asynchronously with GNT and demultiplexed by the audio request signal. Thus the arbiter defaults to the video function at power-up and parks there during no requests for bus access. This is desirable since the video will request the bus more often. However, the audio will have highest bus access priority. Thus the audio will have first access to the bus even when issuing a request after the video request but before the PCI external arbiter has granted access to the Bt879. Neither function can preempt the other once on the bus. The duration to empty the entire video PCI FIFO onto the PCI bus is very short compared to the bus access latency the audio PCI FIFO can tolerate. 430FX Compatibility Mode

When using the 430FX PCI, the following rules will ensure compatibility:

  1. Deassert REQ at the same time as asserting FRAME.

  2. Do not reassert REQ to request another bus transaction until after finish-ing the previous transaction.

Since the individual bus masters do not have direct control of REQ, a simple logical-or of video and audio requests would violate the rules. Thus, both the arbiter and the initiator contain 430FX compatibility mode logic. To enable 430FX mode, set the EN_TBFX bit as indicated in Device Control Register on page 104.

When EN_TBFX is enabled, the arbiter ensures that the two compatibility rules are satisfied. Before GNT is asserted by the PCI arbiter, this internal arbiter may still logical-or the two requests. However, once the GNT is issued, this arbiter must lock in its decision and now route only the granted request to the REQ pin. The arbiter decision lock happens regardless of the state of FRAME because it does not know when FRAME will be asserted (typically - each initiator will assert FRAME on the cycle following GNT). When FRAME is asserted, it is the initiator s responsibility to remove its request at the same time. It is the arbiters responsibility to allow this request to flow through to REQ and not allow the other request to hold REQ asserted. The decision lock may be removed at the end of the transaction: for example, when the bus is idle (FRAME and IRDY). The arbiter decision may then continue asynchronously until GNT is again asserted. Interfacing with Non-PCI 2.1 Compliant Core Logic

A small percentage of core logic devices may start a bus transaction during the same cycle that GNT is de-asserted. This is non PCI 2.1 compliant. To ensure compatibility when using PCs with these PCI controllers, the EN_VSFX bit must be enabled (refer to Device Control Register on page 104). When in this mode, the arbiter does not pass GNT to the internal functions unless REQ is asserted. This prevents a bus transaction from starting the same cycle as GNT is de-asserted. This also has the side effect of not being able to take advantage of bus parking, thus lowering arbitration performance. The Bt879 drivers must query for these non-compliant devices, and set the EN_VSFX bit only if required. Other elements of the tvcards array

If you are trying to make a new card work you might find it useful to know what the other elements in the tvcards array are good for:

video_inputs    - # of video inputs the card has
audio_inputs    - historical cruft, not used any more.
tuner           - which input is the tuner
svhs            - which input is svhs (all others are labeled composite)
muxsel          - video mux, input->registervalue mapping
pll             - same as pll= insmod option
tuner_type      - same as tuner= insmod option
*_modulename    - hint whenever some card needs this or that audio
                module loaded to work properly.
has_radio       - whenever this TV card has a radio tuner.
no_msp34xx      - "1" disables loading of msp3400.o module
no_tda9875      - "1" disables loading of tda9875.o module
needs_tvaudio   - set to "1" to load tvaudio.o module

If some config item is specified both from the tvcards array and as insmod option, the insmod option takes precedence.

7.1.8. Cards


For a more updated list, please check https://linuxtv.org/wiki/index.php/Hardware_Device_Information Supported cards: Bt848/Bt848a/Bt849/Bt878/Bt879 cards

All cards with Bt848/Bt848a/Bt849/Bt878/Bt879 and normal Composite/S-VHS inputs are supported. Teletext and Intercast support (PAL only) for ALL cards via VBI sample decoding in software.

Some cards with additional multiplexing of inputs or other additional fancy chips are only partially supported (unless specifications by the card manufacturer are given). When a card is listed here it isn’t necessarily fully supported.

All other cards only differ by additional components as tuners, sound decoders, EEPROMs, teletext decoders ... MATRIX Vision

MV-Delta - Bt848A - 4 Composite inputs, 1 S-VHS input (shared with 4th composite) - EEPROM


This card has no tuner but supports all 4 composite (1 shared with an S-VHS input) of the Bt848A. Very nice card if you only have satellite TV but several tuners connected to the card via composite.

Many thanks to Matrix-Vision for giving us 2 cards for free which made Bt848a/Bt849 single crystal operation support possible!!! Miro/Pinnacle PCTV

This card is basically the same as all the rest (Bt484A, Philips tuner), the main difference is that they have attached a programmable attenuator to 3 GPIO lines in order to give some volume control. They have also stuck an infra-red remote control decoded on the board, I will add support for this when I get time (it simple generates an interrupt for each key press, with the key code is placed in the GPIO port).

I don’t yet have any application to test the radio support. The tuner frequency setting should work but it is possible that the audio multiplexer is wrong. If it doesn’t work, send me email.

  • No Thanks to Leadtek they refused to answer any questions about their hardware. The driver was written by visual inspection of the card. If you use this driver, send an email insult to them, and tell them you won’t continue buying their hardware unless they support Linux.

  • Little thanks to Princeton Technology Corp (http://www.princeton.com.tw) who make the audio attenuator. Their publicly available data-sheet available on their web site doesn’t include the chip programming information! Hidden on their server are the full data-sheets, but don’t ask how I found it.

To use the driver I use the following options, the tuner and pll settings might be different in your country. You can force it via modprobe parameters. For example:

modprobe bttv  tuner=1 pll=28 radio=1 card=17

Sets tuner type 1 (Philips PAL_I), PLL with a 28 MHz crystal, enables FM radio and selects bttv card ID 17 (Leadtek WinView 601). KNC One

Many thanks to:

  • Markus Schroeder <schroedm@uni-duesseldorf.de> for information on the Bt848 and tuner programming and his control program xtvc.

  • Martin Buck <martin-2.buck@student.uni-ulm.de> for his great Videotext package.

  • Gerd Hoffmann for the MSP3400 support and the modular I2C, tuner, ... support.

  • MATRIX Vision for giving us 2 cards for free, which made support of single crystal operation possible.

  • MIRO for providing a free PCTV card and detailed information about the components on their cards. (E.g. how the tuner type is detected) Without their card I could not have debugged the NTSC mode.

  • Hauppauge for telling how the sound input is selected and what components they do and will use on their radio cards. Also many thanks for faxing me the FM1216 data sheet.
