Hi everyone,
So It's my first time to LinuxTV hacking, debugging etc, so I
apologize if I've failed to provide anything essential.
Anyways, I've just bought a ASUS 'My Cinema Europa Hybrid' (P7131
DVB-T) which has the Phillips saa7131 chipset in it (supported by the
saa7131 module et al). There is a problem getting the firmware in this
card to boot correctly - I may have the wrong card number and I cannot
use i2c because it detects it as UNKNOWN/GENERIC (i.e type 0) which
doesn't work.
According to /usr/share/doc/linux/video4linux etc my card number
should be either 78, 111 or 112. Specifying card=x seems to make the
module somewhat recognize the card, and even though I have the
firmware - it won't actually boot. This is shown by the fact that all
dvb operations essentially just time out and the fact that I cannot
scan channels in software like tvtime. I might be wrong though.
Here is relevant output which might assist in helping the problem:

Thanks in advance,

Hi Sam and everyone
First off I'm new to the LinuxTV mailing list and just like Sam this is my first time hacking, debugging etc.
I also have an ASUS 'My Cinema Europa Hybrid' and it is currently unsupported right now.
However looking over the hardware component's on the card itself, it seems that the individual components seem to be supported
and we merely have to get all the components "interacting" with each other.
The card has a:
* Philips SAA7134HL video decoder, which is supported by the saa7134 driver
* Philips TDA10046A digital demodulator, which is supported by the tda1004x driver
* Philips TDA9886TS analog demodulator, which is supported by the tda9887 driver
I went and compiled and installed the recent 2.6.30 kernel and also a recent v4l-dvb snapshot.
So i can make sure that i have the most recent drivers. It still seems to be unsupported in recent kernels and also v4l-dvb snapshots
I done a modprobe saa7134 i2c_scan=1 so any attached/associated components are scanned and detect.
It seems that the TDA9886TS analog demodulator is detected and i believe the device at 0x10 is the TDA10046A digital demodulator as shown by the dmesg output:

=================================================================================
According to this wiki entry: http://www.linuxtv.org/wiki/index.php/Development:_How_to_add_support_for_a_device
To add support for a new saa7134 card we just need to modify saa7134-cards.c and saa7134.h and
add any card specific details such as vendor/device id, tuner and inputs etc.
So started by modifying those two files, i highly doubt the card will work with just the modifications i have made.
Anyway here's a patch containing what i have modified,
it's mostly copied and pasted from the SAA7134_BOARD_ASUS_EUROPA2_HYBRID section but changed to suit the card

======================================================================================================
Right now with my modifications it is able to pick it up as a "Asus Europa Hybrid OEM" card and also load the drivers for the analog tuner.
My modification has a number of problems such as:
* Not being able to recognise the TDA10046A digital demodulator and load the tda1004x driver.
I believe i have to specify it in the ".tuner_type" line but i don't know what exactly to specify.
* Not being able to recognise/initilze the frontend.
* Analog/Digital scanning fails.
Anyway it's a start, hopefully a developer can help me fix some of the problems mentioned above and get this card supported
Thanks
