[linux-dvb] activy dvb-t ALPS tdhd1-204A support?

Hi,

I have also a AMC 570 with 2 dvb-t tuners. (activy dvb-t model
S26361-D1297-V300 GS2)
(Pcb has a print: ActivyAL BS 03601790A)
The chip is SAA7146AH. I opened the tuner tin box
and only chip that was visible was Epcos X7251D
Lspci gives me almost the
same than below, I think the important part is the 5f60 adress which
means that our cards have alps tdhd1-204a tuners. It seems that
there is no linux support for this card type yet.

I also attached .inf file from the original windows installation if
it gives any help. (I found it here
http://forum.fujitsu-siemens.com/digitalhome/viewtopic.php?f=30&t=5622&st=0&sk=t&sd=a&start=15
and it mentions my card)

I'd appreciate if somebody tells me if it is possible to
create linux support with a quick patch or not.

Hello,

I have a Fujitsu Siemens Activy Media Center 530 with a dvb-t card.

lspci gives me this:
01:04.0 Multimedia controller: Philips Semiconductors SAA7146 (rev 01)
       Subsystem: Philips Semiconductors Unknown device 5f60
       Control: I/O- Mem+ BusMaster+ SpecCycle- MemWINV- VGASnoop- ParErr-
Stepping- SERR- FastB2B-
       Status: Cap- 66MHz- UDF- FastB2B+ ParErr- DEVSEL=medium >TAbort-
<TAbort- <MAbort- >SERR- <PERR-
       Latency: 32 (3750ns min, 9500ns max)
       Interrupt: pin A routed to IRQ 17
       Region 0: Memory at fddff000 (32-bit, non-prefetchable) [size=512]

The saa7146 driver doesn't find the card - a no /dev/dvb* devices are created.

I found this in the archives:
http://linuxtv.org/pipermail/linux-dvb/2007-January/015133.html
however my device is 5f60 where his card had 5f61

I took the attached patch
http://www.linuxtv.org/pipermail/linux-dvb/attachments/20070103/46dbb191/activy-0001.obj
and changed all occurrences of 5f61 to 5f60.

a "make reload" gave me this in dmesg:
saa7146: register extension 'budget dvb'.
ACPI: PCI Interrupt 0000:01:04.0[A] -> GSI 19 (level, low) -> IRQ 17
saa7146: found saa7146 @ mem e08ba000 (revision 1, irq 17) (0x1131,0x5f60).
saa7146 (0): dma buffer size 192512
DVB: registering new adapter (TT-Budget/WinTV-NOVA-T  PCI)
adapter failed MAC signature check
encoded MAC from EEPROM was
ff:ff:ff:ff:ff:ff:ff:ff:ff:ff:ff:ff:ff:ff:ff:ff:ff:ff:ff:ff
test_config / it = 0
budget: A frontend driver was not found for device 1131/7146 subsystem
1131/5f60
You must set an I/O address with io=0x20c or io=0x30c

And /dev/dvb/adapter0 showed up!
But only these devices are created:
/dev/dvb/adapter0/demux0
/dev/dvb/adapter0/dvr0
/dev/dvb/adapter0/net0
...so interface0 is missing (as the message "A frontend driver was not found"
says allready)


What could I do, to get my card working?
thanks,
niko
