Re: [linux-dvb] GDI Black Gold [14c7:0108] cx88 card

[Tim Small]

Hello,

I'm interested in getting this card working under Linux as well, it's 
labelled GDI2500PCTV on the back, and has a Conexant CX23881 visible on 
the front, with a Philips "TU1216/1 H P" RF box...  Looks like there may 
be some more ICs under the metal box, but I'd have to desolder it to 
check what they were (which I can do if necessary).

There seems to be TU1216 support in both v4l/saa7134-dvb.c and 
v4l/budget-av.c (code cut-n-paste by the look of it), but I can't see a 
way to select this tuner with the cx88xx module (e.g. CARDLIST.tuner).

So... I'm game for trying to get this working, and have a bit of kernel 
programming experience, but is there anything else I'm likely to need to 
know before I set out on this?

Cheers!

Tim.

Re: [linux-dvb] GDI Black Gold [14c7:0108] cx88 based DVB-T card

[Tim Small]

Hello,

I'm interested in getting this card working under Linux as well, it's
labelled GDI2500PCTV on the back, and has a Conexant CX23881 visible on
the front, with a Philips "TU1216/1 H P" RF box...  Looks like there may
be some more ICs under the metal box, but I'd have to desolder it to
check what they were (which I can do if necessary).

According to the preliminary datasheet which I found, the TU1216
contains a TDA 10046 Channel Decoder, and a TDA6651 Mixer/Oscillator.

There seems to be TU1216 support in both v4l/saa7134-dvb.c and
v4l/budget-av.c (code cut-n-paste by the look of it), but I can't see a
way to select this tuner with the cx88xx module (e.g. CARDLIST.tuner),
unless it's called something different, or is compatible with another
Philips tuner.

So... I'm game for trying to get this working, and have a bit of kernel
programming experience, but is there anything else I'm likely to need to
know before I set out on this?

Cheers!

Tim.

since there is no analog TV tuning support you use TUNER_ABSENT in
cx88-cards.c like SAA7134_BOARD_VIDEOMATE_DVBT_200 and
SAA7134_BOARD_PHILIPS_TOUGH do in saa7134-cards.c accordingly.

You then need to implement the functions they call in saa7134-dvb.c
accordingly to cx88-dvb.c and find out if the tuner address is 0x60 or
0x61.

	case SAA7134_BOARD_PHILIPS_TOUGH:
		fe0->dvb.frontend = dvb_attach(tda10046_attach,
					       &philips_tu1216_60_config,
					       &dev->i2c_adap);
		if (fe0->dvb.frontend) {
			fe0->dvb.frontend->ops.tuner_ops.init = philips_tu1216_init;
			fe0->dvb.frontend->ops.tuner_ops.set_params = philips_tda6651_pll_set;
		}

For testing, on a first look, you need to introduce the tda10046
including firmware upload #include "tda1004x.h" and at least adapt these
functions to cx88-dvb.

What could be factored out to avoid code duplication is another later
