[linux-dvb] Terratec Cinergy C HD - CAM support.... Need help?

[Willem van Asperen]

Hi All,

I need something but willing to help out!

I just got my Terratec Cinergy C HD card. After relatively minor issues I got 
the card running on my Mandriva 2010.2 (kernel 2.6.33) myth box.

But... I am getting my DVB-C signal from the Ziggo (former Casema) network. I 
found a post that claims that all channels are encrypted (except for Nederland 
1). Even though these are the standard channels that you also get when you 
just have an analog subscription.

So. I need CAM support. After a couple of nights swimming the net I come to 
the conclusion that

a) CAM support is currently not implemented
b) This support has been not implemented for quite some time
c) There are more people that would like it to work...

So, dear people, is anyone working on getting the CAM to work on the Terratec 
Cinergy C HD card, but having problems? Is there any way, shape or form that I 
can assist in getting this support done?

Or have we given up on this card and should I just take my loss and go for 
another card... If so, which one?

Thanks,
Willem

For all cards?

I use TNT/dvb sticks, and you should be able to decode HD video with a 
so called "no hd" usb stick.

Because it is a question of software, not hardware.

Maybe, if one CAM card works, you should look for it ...

The CA code in the mantis driver isn't actually hooked into the driver
anywhere, so that't correct: No CAM will currently work with the
Terratec Cinergy C HD.

Exported, but never called:

 bjorn@canardo:/usr/local/src/git/linux-2.6/drivers/media/dvb/mantis$ grep mantis_ca_init *.c
 mantis_ca.c:int mantis_ca_init(struct mantis_pci *mantis)
 mantis_ca.c:EXPORT_SYMBOL_GPL(mantis_ca_init);


I don't know why, but I assume it's the same as with the remote control
code that was recently fixed Christoph Pinkl: The code probably wasn't
considered production ready when the driver was merged, and was therefore
"temporarily" disabled until it could be fixed.

Can anyone confirm this and, if so, is someone working on getting this fixed?

Like I said, happy to dig in and see if I can help here. But I would at least 
need to know what the current status is and an idea where the problem(s) sit.

Regards,
Willem

Actually, doing this on s2-liplianin-41388e396e0f (the one I downloaded today) 
gets:
$ grep mantis_ca_init *.c

mantis_ca.c:int mantis_ca_init(struct mantis_pci *mantis)
mantis_dvb.c:   mantis_ca_init(mantis);

And in the function __devinit mantis_dvb_init(struct mantis_pci *mantis) it 
actually says:

...
	dvb_net_init(&mantis->dvb_adapter, &mantis->dvbnet, &mantis->demux.dmx);
	tasklet_init(&mantis->tasklet, mantis_dma_xfer, (unsigned long) mantis);
	mantis_frontend_init(mantis);
	mantis_ca_init(mantis);

	return 0;
...

So it seems that this mantis_ca_init call is actually made nowadays.

I'll do some more digging -- check the /var/log/messages file for output of the 
mantis initialization -- and report back.

In the s2-liplianin yes.  Not in mainline.  Investigating the
differences might be useful.

Indeed.

% modprobe -r mantis
% modprobe mantis

gives:
May 29 14:37:51 mythbox kernel: Mantis 0000:03:02.0: PCI INT A -> GSI 17 
(level, low) -> IRQ 17
May 29 14:37:51 mythbox kernel: DVB: registering new adapter (Mantis DVB 
adapter)
May 29 14:37:52 mythbox kernel: DVB: registering adapter 0 frontend 0 (Philips 
TDA10023 DVB-C)...


Nothing about CA
