Good News,Open source code for TBS Card has been released

[Alfredo]

Hi

After doing:

git clone --depth=1 https://github.com/tbsdtv/linux_media.git -b latest ./media

cd media_build does not work because the directory media_build not exist.

Is problem with my git or with yours git?

Regards and thanks

Hi crazycat

I had put myself in the head that was similar to that of: https://www.linuxtv.org/wiki/index.php/ ... ce_Drivers
thence that I haven't use the first command.

Thanks you very much.

[crazycat]

Also you can just clone media_build and run:

Code: Select All Code

./build --main-git
sudo make install


But this clone entire kernel sources + linux_media subtree. So this more suitable for developers.

i tried the latest driver with debian testing 4.9 kernel and i got the following error:

PS. I tried 4.10-rc6 too. same error

Some weeks ago I found some issues with the new open source driver and I don't know if anyone works on it?

• My older cards TBS-6981 and TBS-8922 get not the right names in syslog, dmesg ...
  I described these at this point http://www.tbsdtv.com/forum/viewtopic.php?f=86&t=9960&start=70#p36701
  .
• My older TBS-6981 card get no value for SNR (Signal-to-Noise Ratio). With the old driver I get a real value.
  I described this at this point http://www.tbsdtv.com/forum/viewtopic.php?f=86&t=9960&start=70#p36722
  .
• My TBS-6205 card (tested with DVB-T) has a low value for STR/SNR (Signal Strength / Signal-to-Noise Ratio) in comparison to the old driver at the same antenna/hardware. For example:
  * old driver STR/SNR are 70 / 100
  * new driver STR/SNR are 30 / 47
  .

This issues are all only with the new open source driver (tested today with the actual driver) and so I hope that anyone find a solution to fix this issues.
That will be very great!

• Implemented, please check updated.
  cx88: Set frontend name for TBS 8922 as product name.
  cx23885: Set frontend name for TBS 6920, 6980, 6981 as product name.
• Look like cx24117 driver implemented from 'reversed' code. So lack many features or partial implementation. But anyway Connexant demods is "total pain" and nobody want touch it
• si2168 demod driver provide legacy SNR(%) = SNR(dB)*2, Strength(%) = 100 + RFLevel(dBm). Anyway extended signal statistic provided as SNR(dB). Strength(dBm).

@crazycat,
I've tested the new driver version and I get the following results in the linux console after put in:

dmesg | grep "registering adapter"

Code: Select All Code

cx88-mpeg driver manager 0000:05:01.2: DVB: registering adapter 0 frontend 0 (TBS 8922 DVB-S/S2)...
cx23885 0000:02:00.0: DVB: registering adapter 1 frontend 0 (TurboSight TBS 6981)...
cx23885 0000:02:00.0: DVB: registering adapter 2 frontend 0 (TurboSight TBS 6981)...
TBSECP3 driver 0000:06:00.0: DVB: registering adapter 3 frontend 0 (TurboSight TBS 6205 DVB-T/T2/C )...
TBSECP3 driver 0000:06:00.0: DVB: registering adapter 4 frontend 0 (TurboSight TBS 6205 DVB-T/T2/C )...
TBSECP3 driver 0000:06:00.0: DVB: registering adapter 5 frontend 0 (TurboSight TBS 6205 DVB-T/T2/C )...
TBSECP3 driver 0000:06:00.0: DVB: registering adapter 6 frontend 0 (TurboSight TBS 6205 DVB-T/T2/C )...


The result is good, with a small issue: Missing "DVB-S/S2" at TBS-6981.

I hope, the other both points will be fixed later, if the driver will be get "stable"!
