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.

Also you can just clone media_build and run:

Code: Select all

./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

check with latest commit - https://github.com/tbsdtv/linux_media/c ... 40e334623a

looks like its working. thanks a lot.

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!

@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

cx88-mpeg driver manager 0000:05:01.2: DVB: registering adapter 0 frontend 0 (TBS 8922 DVB-S/S2)...

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"!
