Making it Work

It supports MythTV mythbuntu building: s

  1. Update the install with update/upgrade
  2. Install TBS drivers as per TBS6285 instructions
  3. nothing was added to the /var/log/syslog or dmesg output
  4. reboot the system
  5. I found "disagrees about version of symbol dvb_frontend_detach" messages in the dmesg output, so follow instructions for this at the TBS forum [1]
     a. cd to the "tbs-linux-drivers" subdirectory
     b. move or delete the contents of the kernel library drivers/media subdirectory using 
        "sudo mv /lib/modules/$(uname-r)/kernel/drivers/media ~/.media.bak" or 
        "rm -Rf /lib/modules/3.8.0-29-generic/kernel/drivers/media" (this is for Ubuntu based systems)
     c. reinstall drivers using "sudo make install"
     d. reboot the system

This gives working card drivers loaded and seen during the boot sequence.

When the kernel is updated (due to security updates), then I found the TBS help wiki's fedora installation instructions useful. These are:

  1. cd to the "tbs-linux-drivers" subdirectory
  2. move or delete the contents of the kernel library drivers/media subdirectory using 
     "sudo mv /lib/modules/$(uname -r)/kernel/drivers/media ~/.media.bak" or 
     "rm -Rf /lib/modules/3.8.0-29-generic/kernel/drivers/media" (this is for Ubuntu based systems)
  3. Reconfigure the drivers. For this I found the following steps which worked for me.
     a. clean out the code and reset the installation kernel data using the "sudo make distclean" command
     b. rerun the installation settings script with the "sudo ./v4l/tbs-x86_64.sh" command
     c. configure the driver settings (this is a guess) using the "sudo make release" command
     d. configure the driver settings (this is a guess) using the "sudo make menuconfig" command. 
        I enabled the "Enable drivers not supported by this kernel" which on hindsight should be left unchecked. 
        The fedora instructions said to just exit this. 
  4. rebuild the driver using the "sudo make" command (this will take a while)
  5. reinstall drivers using the "sudo make install" command
  6. load newly installed driver using the "sudo modprobe -v tbs62x0fe" command
  7. reboot the system

The installation now uses and installs to the latest kernel's "/lib/modules/" directory.
