tuning failed with linux kernel 3.1 Arch

[temocles0918]

Hi
I have problems con my tuner TBS8920. In windows (64 bits) work perfectly, in linux con kernel 3.1 (x86_64) no!!!. I download the last driver (linux-tbs-sources_111017) and compiled perfectly.. the card is detected by linux..

ERROR: Sorry - i couldn't get any working frequency/transponder
 Nothing to scan!!


is it drivers ?? or not.. my configuration in windows and linux it same (LNB, multiswitch, etc). Windows with dvdream perfect!!.. i need it for my new HTPC with Mythtv.. Some idea ?

Thanks.. in advance..... Regards.

Maybe this thread is based on the same bug in the driver. Also no channels can be found.

Mmm.. maybe.. This card (8920) have problems in other kernel versions, I had a debian lenny, mmm i believed with kernel 2.6.35rc, but with news drivers (thanks cody), work, until that i lost my HDD and my information with my pc, these past few months ..

i bought others components for other computer (type HTPC) and i installed a new linux distribution with your ultimate kernel (3.1), compile perfectly, but not work. the same..

The card is excellent, but my firt systems is in linux.. not like windows..

[temocles0918]

Mmm.. new driver V111115. i compiled..
The same, not signal

Hi temocles0918.
Can you say me witch satellite are you trying to lock? And can you post the content of your sat_old.conf ?
Remember, TBS8920 haven't got blindscan hardware and need all real parameters to lock.

Best regards.

Hi.. thanks

My file sat_old.conf

I am make test with Intelsat 9.
in kaffeine, the card have signal (power), however not unlocked.. . In windows 7, work card perfectly with dvbdream.. my subscripter receiver have signal

Hi
I guess your problem is unrelated to drier, but v4l-dvb support for 64bit kernels. There is issue that not all IOCTL have alreaday made translations from 32bit to 64bit. Check your dmesg after try to tune with kaffeine if you see there messages related to ioctl32 errors.
Currently it will affect some set of popular appliactions use frontend ioctls calls, I have to note kaffeine, dvblast, couple from dvb-apps...
Simply if you are using some 32bit appliactions which are doing some FE ioctls calls thay will not work because in dvb kernel are not made till yet some part of new code. You have to compile kernel into 32bit to be iocatl calls supported as they exist currently.

At least it works for me such.
