No saa7134-dvb.c so cannot modify firmware for DVB-T?

To get the Peak DVB-T IDE multimedia card working in dvb-t it seems to be necessary to mess about with firmware according to the following recipe, which is for Gentoo:

Quote:

Troubleshooting on card [1043:4876]
In /usr/src/linux/drivers/media/video/saa7134/saa7134-dvb.c, line 873, struct tda1004x_config philips_tiger_config
change the entry
.request_firmware = NULL,
to
.request_firmware = philips_tu1216_request_firmware,
run /usr/src/linux/Documentation/dvb/get_dvb_firmware and copy the dvb-fe-tda10046.fw to /lib/firmware
modprobe saa7134 card=78 gpio_tracking=1
see http://www.spinics.net/lists/vfl/msg27672.html
STOP PRESS - the Mercurial version "emerge v4l-dvb-hg" gives the card a proper card number of 112.
The card can then be brought up with "modprobe saa7134 card=112 tuner=54 gpio_tracking=1 i2c_scan=1". You may also need to modprobe saa7134-dvb and saa7134-alsa. This works now but may not continue to do so.

But there seems to be no /usr/src/linux/drivers/media/video/saa7134/saa7134-dvb.c file, or anything like it on the computer. (Debian Etch AMD64). So I cannot change line 873 like it wants.

Any suggestions? TIA. Hang on, the file isn't tda1004x_config or something is it?

You'll probably need the full kernel sources to get that file. Use aptitude or apt-get to install the kernel sources, then that file will exist and can be modified. The Gentoo instructions should work fine for Debian as well.

I've got the kernel-headers package installed, thought that was the same thing?? It may well not be configured correctly - have had messages from box perhaps to that effect.

They are similar, but not the same. The headers are just that, the headers of the full source. To do what is asked of you, you'll want the full source.

This has been discussed here previously -

Great thanks, done that, at least downloaded it. As it happens the source, little pun, of much of my confusion was the absence of the word 'kernel': it's called 'linux-source'.

Did as you said and got the right file and modified it. So - sorry to be retarded - I now have to make the module from the source code do I?

You couldn't point me to how??
