Optional Arguments for Loading Modules</H1 ><P CLASS="LITERALLAYOUT" ><br> <B CLASS="COMMAND" >videodev.o</B ><br> -----------------------------<br> <br> This is the basic video4linux module, all video <br> drivers (incl. bttv) register themselves here.<br> <br> <br> <br> <B CLASS="COMMAND" >i2c.o</B ><br> ------------------------<br> <br> The generic i2c module. It does much of the i2c bus<br> management, all other modules (except videodev.o)<br> use this one.<br> <br> modprobe args:<br> <B CLASS="COMMAND" >scan=1</B > scan the bus for i2c devices<br> <B CLASS="COMMAND" >verbose=0</B > shut up i2c<br> <B CLASS="COMMAND" >i2c_debug=1</B > for debugging, it sticks the <br> whole (software) i2c bus traffic to the syslog<br> <br> <br> <B CLASS="COMMAND" >bttv.o</B ><br> -------------------------<br> <br> The bt848 (grabber chip) driver.<br> <br> modprobe args:<br> <B CLASS="COMMAND" >remap=adr</B > remap Bt848 memory to address less than 20 <br> <B CLASS="COMMAND" >vidmem=base</B > frame buffer address over 20 (of <br> graphic card)<br> <B CLASS="COMMAND" >triton1=0/1</B > for Triton1 compatibility; Triton1 is <br> automatically recognized but this might also help with other chipsets<br> <B CLASS="COMMAND" >pll=0/1/2</B > pll settings (<B CLASS="COMMAND" >0</B >: don't use PLL; <B CLASS="COMMAND" >1</B >: 28 MHz crystal installed<br> <B CLASS="COMMAND" >2</B >: 35 MHz crystal installed<br> <B CLASS="COMMAND" >radio=0/1</B > card supports radio<br> <B CLASS="COMMAND" >card=</B ><EM >n</EM > card type: see the next section for the complete list;<br> remap, card, radio and pll accept up to four comma-separated arguments<br> (for multiple boards). The CARD and PLL defines from the Makefile<br> are used as defaults.<br> <br> <br> <br> <B CLASS="COMMAND" >msp3400.o</B ><br> ----------------------------<br> <br> The driver for the msp34xx sound processor chips. If you have a<br> stereo card, you probably want to modprobe this one.<br> <br> modprobe args:<br> <B CLASS="COMMAND" >debug=1/2</B > print some debug info to the syslog, 2 is more verbose.<br> <br> <br> <br> <B CLASS="COMMAND" >*tea6300.o</B ><br> -----------------------------<br> <br> The driver for the tea6300 fader chip. If you have a stereo<br> card and the msp3400.o doesn't work, you might want to try this<br> one. This chip is seen on most STB TV/FM cards (usually from<br> Gateway OEM sold surplus on auction sites).<br> <br> modprobe args:<br> <B CLASS="COMMAND" >debug=1</B > print some debug info to the syslog.<br> <br> <br> <br> <B CLASS="COMMAND" >*tda8425.o</B ><br> -----------------------------<br> <br> The driver for the tda8425 fader chip. This driver used to be<br> part of bttv.c, so if your sound used to work but does not<br> anymore, try loading this module.<br> <br> modprobe args:<br> <B CLASS="COMMAND" >debug=1</B > print some debug info to the syslog.<br> <br> <br> <br> <B CLASS="COMMAND" >*tda9855.o</B ><br> -----------------------------<br> <br> The driver for the tda9855 stereo decoder / audio processor chip.<br> <br> modprobe args:<br> <B CLASS="COMMAND" >debug=1</B > print some debug info to the syslog.<br> <br> <br> <br> <B CLASS="COMMAND" >*dpl3518.o</B ><br> -----------------------------<br> <br> Driver for the dpl3518a Dolby Pro Logic Processor.<br> <br> modprobe args:<br> <B CLASS="COMMAND" >debug=1</B > print some debug info to the syslog.<br> <br> <br> <br> <B CLASS="COMMAND" >tuner.o</B ><br> --------------------------<br> <br> The tuner driver. You need this unless you want to use only<br> with a camera or external tuner.<br> <br> modprobe args:<br> <B CLASS="COMMAND" >debug=1</B > print some debug info to the syslog<br> <B CLASS="COMMAND" >type=</B ><EM >n</EM > type of the tuner chip. n as seen in <A HREF="modprobe.html" >Section 4</A ><br> <br> <br> <br> <B CLASS="COMMAND" >i2c_chardev.o</B ><br> --------------------------------<br> <br> Provides a character device for i2c bus access. Works for 2.1.x<br> only, not compiled by default.<br> </P ></DIV ><DIV CLASS="NAVFOOTER" ><HR ALIGN="LEFT" WIDTH="100%"><TABLE SUMMARY="Footer navigation table" WIDTH="100%" BORDER="0" CELLPADDING="0" CELLSPACING="0" ><TR ><TD WIDTH="33%" ALIGN="left" VALIGN="top" ><A HREF="apps.html" ACCESSKEY="P" >Prev</A ></TD ><TD WIDTH="34%" ALIGN="center" VALIGN="top" ><A HREF="index.html" ACCESSKEY="H" >Home</A ></TD ><TD WIDTH="33%" ALIGN="right" VALIGN="top" ><A HREF="cards.html" ACCESSKEY="N" >Next</A ></TD ></TR ><TR ><TD WIDTH="33%" ALIGN="left" VALIGN="top" >Television Applications</TD ><TD WIDTH="34%" ALIGN="center" VALIGN="top" > </TD ><TD WIDTH="33%" ALIGN="right" VALIGN="top" >Bt8x8 Cards by Number</TD ></TR ></TABLE ></DIV ></BODY ></HTML >
