TT-S1500 budget-ci registeration

TT-S1500 budget-ci registeration

[Thomas Kernen]

Hello to all,

I'm currently testing a TT-S1500 budget card with the TT budget CI 
adapter with vl4 tree and kernel 2.6.28.

When I modprobe budget_ci, the CI adapter seems to be detected but not 
registered in /dev/dvb/adapter3/ca0 as I would have expected it to be.

Instead I see the following output:

[  148.664846] input: Budget-CI dvb ir receiver saa7146 (0) as 
/devices/pci0000:00/0000:00:1e.0/0000:11:09.0/input/input5

Any suggestions/ideas what the cause may be and how I can attempt to 
solve this?

Thanks
Thomas

And I realised I cut and pasted the wrong line: I was expecting to see 
"budget_ci: CI interface initialised" after the other line but nothing 
of the like did appear. Nor any line indicating an error.

As one can see from the lspci the drivers claim to be in use:

11:09.0 Multimedia controller: Philips Semiconductors SAA7146 (rev 01)
	Subsystem: Technotrend Systemtechnik GmbH Device 1017
	Control: I/O- Mem+ BusMaster+ SpecCycle- MemWINV- VGASnoop- ParErr+

	Latency: 123 (3750ns min, 9500ns max)
	Interrupt: pin A routed to IRQ 23
	Region 0: Memory at d0220000 (32-bit, non-prefetchable) [size=512]
	Kernel driver in use: budget_ci dvb
	Kernel modules: budget-ci

Am I missing a point here? I can't find anything that addresses this in 
the LinuxTV wiki or in the archives of the mailing list.

Thanks
Thomas

It would appear that I enjoy speaking to myself on this mailer ;-)

Anyway, good news is that the issue had to do with a defective cable 
that was bridging the Budget CI and the TT S-1500. It is now functional 
and descrambles the Viaccess streams I needed to test against.

Later today I will update the wiki pages with the details of my setup:

Hopefully this might be useful to others too.
