Making it Work

As of (2012-02-14) it is now possible to tune into DVB-T & DVB-T2 at the same time, both recorded and live, following the release of Linux Driver v120216. This version will also now compile on all Linux Kernels up till 3.2.x. Instructions for compiling/installing remain identical.

These instructions can all be carried out as a non-root user, until "make install".

• Download driver zip from the manufacturer and unpack the files

wget http://www.tbsdtv.com/download/document/common/tbs-linux-drivers_v130506.zip
mkdir tbs-linux-drivers_v130506
cd tbs-linux-drivers_v130506
unzip ../tbs-linux-drivers_v130506.zip

Note: The next lines are explained in more detail in the manifacturers README: README_TBS62XY, linking to README_TBS6981

tar axvf linux-tbs-drivers.tar.bz2
cd linux-tbs-drivers

• At this point, the supplied tar.bz2 is completely knackered in respect of the file permissions. To fix run

 find -type d -exec chmod 755 \{\} \;
 find -type f -exec chmod 644 \{\} \;
 find -name '*.sh' -exec chmod 755 \{\} \;
 find -name '*.pl' -exec chmod 755 \{\} \;

• We need to choose 32bit or 64bit for our drivers. Run
  • ./v4l/tbs-x86.sh for 32bit;
  • ./v4l/tbs-x86_r3.sh for 32bit running kernel 3.x
  • ./v4l/tbs-x86_64.sh for 64bit.

• We're ready to build; add -j3 for a faster build on a dual core machine, -j5 on a quad core machine, etc.

 make -j3

• Once that has completed, you can install

 sudo make install

• And reboot.

Sample kernel output

 SAA716x TBS 0000:02:00.0: PCI INT A -> GSI 16 (level, low) -> IRQ 16
 SAA716x TBS 0000:02:00.0: setting latency timer to 64
 DVB: registering adapter 0 frontend 0 (TurboSight TBS 62x0 DVBT/T2 frontend)...
 DVB: registering new adapter (SAA716x dvb adapter)

troubleshooting

• disagrees about version of symbol dvb_frontend_detach http://www.tbsdtv.com/forum/viewtopic.php?f=47&t=8195

Re-installing after a kernel upgrade

• cd to the linux-tbs-drivers directory that was created in the Making it Work section above.
• Clean out the previously built objects

 make clean

• Choose 32bit or 64bit for our drivers again.
  • ./v4l/tbs-x86.sh for 32bit
  • ./v4l/tbs-x86_r3.sh for 32bit running kernel 3.x
  • ./v4l/tbs-x86_64.sh for 64bit.
• Remove (or rename if you're paranoid) the config file; it will be regenerated automatically.

 rm v4l/.version

• Build and install the modules

 make -j3
 sudo make install

• Reboot your machine.
