TBS 6980 Dual DVB-S2 PCIe card
Hi!
I read the old thread about this card, at
http://www.mail-archive.com/[email protected]/msg12753.html. I've also tried downloading the vendor-provided drivers from
http://www.buydvb.net/download2/TBS6980/tbs6980linuxdriver2.6.32.rar
As someone has already indicated, it seems like TBS (TurboSight) have made their own fork of v4l where the drivers for this card is included. I've also understood that the card works fine, which is nice (I down own it yet but am considering getting one).
Has anyone done any attempt at contacting TBS to see if they can release their changes under the GPLv2? Ideally, they would provide a patch themselves, but it should be fairly simple to diff the linux/ trees from their provided linux-s2api-tbs6980.tar.bz2 file with the stock Linux 2.6.32 code... in fact, it could be that their patch is so trivial that we could just include it in the stock Linux kernel without asking them for license clarifications... but obviously, if we can get a green sign from them, it would be even better. --
Best regards,
Per Lundberg

It is always the other way round.
In the end they need a green sign from us.

BTW, the TBS dual seems to be fine on m$, but there are some mysterious lockups without any trace, if used in conjunction with some prior S2/HDTV cards. I can't tell yet, if that it is evenly distributed over amd/ati and nvidia stuff or whatever on win7 ... , but people do spend lifetime in vain on it.

Well... I guess we are both right. :-) They need to assert ownership and license the code under the GPL, and we need to ensure that the quality of the code is high enough (driver is working and does not interfer with other parts of the code base...).

This is pretty interesting, do you have any references? (forum links or similar)
In my particular case, I was thinking about using it as the "only" S2 card in the machine, later possibly adding a DVB-C card if/when we get cable... so, it might not be a problem for me, but it still doesn't feel really good. I guess the card is pretty new, so maybe (hopefully) it will get fixed by a new firmware release.
Do we have any readers of this list who own the card and use it in Linux (with the drivers from TBS)? Could you please share your
experiences: is the picture quality good? Sound? Does the tuner work well? (e.g. can you receive all channels you normally receive...)

We I asked TBS' support about this question they told me they would like to get it out under GPL as it has been done with other cards they sell but that right now it was not possible due to legal contraints related to some of the code in use by some of the chips on the board. No further details were provided.

Yes I use the card. Have had it for a couple of months now running in a server that acts as a video head-end in my test network. I only tune to specific transponders when I boot the server so I can't really comment on tuning time and related issues. Yes I've used it for S and S2 feeds and so far it fits my requirements.
HTH,

no, they must provide GPLed code accepted by NXP or someone else will do it. We can't assure quality of code we can't see.

No, a friend recently bought that card in addition to a Terratec S2 PCI for his new windows 7 he already had. Likely totally unrelated to linux, but on his stuff it turned out he can't use both cards at once, single both are fine.

Sorry, can't help much yet and can't add anything new.
For now I advised better not to try with binary blobs on linux, he was already burned enough on win7. He might try later and we will have it under GPL sooner or later.

Hermann
