Looking for original source of an old DVB tree

Hello,

Short version:
I am looking for the original source code of a Linux DVB tree containing in particular
drivers/media/dvb/dibusb/microtune_mt2060.c
and the directory

    drivers/media/dvb/dibusb/mt2060_api

Googling for microtune_mt2060.c and mt2060_api is no help. Could anyone kindly point me in the right direction, please?

Longer version:
I am trying to get my USB DVB-T stick running on my Xtreamer.
Xtreamer uses an old 2.6.12.6 kernel heavily modified by Realtek and possibly also modified by MIPS. I have the source code but it would be a tremendous effort to change to a recent kernel. The DVB subtree seems to have been dirtily hacked by Realtek to support their frontends. In the process they seem to have lost support for other frontends.
I have been trying to find the source code for the original version.
I have found nothing resembling it in kernel.org, linux-mips.org and linuxtv.org.

TIA.

Cheers,
Chris

It is mt2060.c, mt2060_priv.h (IIRC) and mt2060.h.

I am not sure what kind of device Xtreamer is, but try this:
http://linuxtv.org/hg/~anttip/rtl2831u/

It is for Realtek RTL2831U + MT2060 based USB sticks.

Hello,

Thanks for your reply, Antti.

Sorry, I did not explain my problem clearly enough.
The DVB subtree in the Realtek 2.6.12.6-VENUS kernel used on the Xtreamer is *very* different from that in mainline 2.6.12.6. It is also different from anything I have found anywhere else.
Judging from the code it looks as though Realtek got the source code from elsewhere and hacked it dirtily for their own chips. I was trying to find the original unhacked source code.
I *do* have the (hacked) files.
The file and directory I cited seem to be specific to this version.
I gave them to see if they ring a bell with anyone.
(A thought: maybe they could have come directly from a DiBcom SDK?)

The Xtreamer is a cheap network media player based on the Realtek RTD1283 SoC.

I am not looking for support for Realtek DVB chips.
I was trying to get an Artec T14 USB DVB-T stick running on the Xtreamer. (This looked the most promising of the sticks I have.)

In the end I bit the bullet and backported the current tip of v4l-dvb to 2.6.12.6. This was not trivial as many modifications were needed :(

I now have modules that load and which *nearly* work.
Scan outputs ">>> tuning status == 0x02" then ">>> tuning status == 0x1a" and sticks there with no further output (for hours; probably indefinitely). This status seems to indicate a problem with FEC.
I guess there are uncorrectable Reed-Solomon errors.

I live in a low signal area and this could be normal. Is there a LNA on this stick?
I couldn't find a module parameter to activate one.

Anyway I now think the best idea would be to for me to get the stick running on x86 first.

Thanks again for your help.

Cheers,
Chris
