[linux-dvb] Missing frontend for Lorenzen LS DVB-T

["Jens Herrmann" <jens1975herrmann@web.de>]

Hi,

I recently bought a Lorenzen SL DVB-T pci card for my computer. It works on Win2k (though awfully slowly), so I tried to install it on linux.

After some fiddeling I managed to compile the driver (Version 1.0.0-pre3), libdvb (0.4.0) and some dvbtools (0.4).

For make'ing insmod I had to add this line to saa7146_core.c:

static struct pci_device_id saa7146_pci_tbl[] __devinitdata = {
    // ... some other stuff
    { PHILIPS_SAA7146, 0x13c2, 0x1011, CARD_INFO ttbt }
};

Now that's my try to tune some channels:

grosser:/usr/src/dvb/DVB/driver# dvbtune -f 346000000 -i
frontend: 4FRONTEND DEVICE: : No such device

Same with scan:

grosser:/usr/src/dvb/DVB/apps/scan# ./scan
using '/dev/dvb/adapter0/frontend0' and '/dev/dvb/adapter0/demux0'

ERROR: failed opening '/dev/dvb/adapter0/frontend0' (No such device)

Of course did I run makedev.napi, all devices seem to be there:

grosser:/dev/dvb# ls adapter0
audio0 ca0 demux0 dvr0 frontend0 net0 osd0 video0

Then I realized that always people posting their /var/log/messages had something like
"DVB: registering frontend 1:0 (Alps BSRV2)..."
(or similar) in their log.

I don't:
Jun 4 19:55:42 grosser kernel: Linux video capture interface: v1.00
Jun 4 19:55:43 grosser kernel: DVB: registering new adapter (TT-Budget/WinTV-NOVA-T PCI).
Jun 4 19:55:43 grosser kernel: PCI: Found IRQ 10 for device 00:0c.0
Jun 4 19:55:43 grosser kernel: saa7146_core.o: adjusting pci latency to 64

So I think it's about a missing frontend driver for my card. Is there
something I can do beneath writing my own? (which I certainly can't...)

Some additional information:

The label on the metal case of the card says:
TDM 1316L/IHP
3112 297 1317L*
0311 SV22 00000

Some data from my pci bus:
grosser:/dev/dvb# lspci -vvv
...

grosser:/dev/dvb# pcitweak -l

PCI: 00:0c:0: chip 1131,7146 card 13c2,1011 rev 01 class 04,80,00 hdr 00

What do you think? May I soon watch television instead of working?

Thanks, Jens.
