Installing the driver breaks DVB-T adapter.

[JeroenM]

Hi there!
I received the cards yesterday and they work great what i can see so far.
But... I have a DVB-T adapter installed as well wich dissapeared after the install of the tbs 6981 drivers.
I´m not so very familiar with linux drivers, but i suspect the drivers dissapear because of the tbs v4l drivers replace the git v4l drivers i use for the dvb-t adapter. Correct?
If so... How can i use drivers from both v4l directories?

if i do: make install in the v4l git directory my dvb-t card works but not the tbs ones.
if i do: make install in the v4l TBS directory my TBS cards work but not the dvb-t one.

My system:
Ubuntu server 11.04 x86
2x TBS 6981 PCIe Adpaters.
1x HVR-1300 DVB-T PCI Adapter.
Tv Backend: HTS TvHeadend

Unfortunately TBS are using an older, incompatible set of v4l drivers. So when you build and install the TBS ones the git ones are overwritten. I ran into the same problem and the only solution is to separate the changes made by TBS and apply them to the git tree. Fortunately I've done that and you can download the patch for 2.6.38 from here:
http://www.softsystem.co.uk/download/tbs/tbs698x-2.6.38.patch
or for 2.6.39 from here:
http://www.softsystem.co.uk/download/tbs/tbs698x-2.6.39.patch

Then you need to download and extract TBS's frontend drivers for the 6921, 6980 and 6981:

Code: Select All Code

wget http://www.tbsdtv.com/download/common/linux-tbs-drivers_110806.rar
mkdir tbs && cd tbs
unrar x ../linux-tbs-drivers_110806.rar
tar -axf linux-tbs-drivers.tar.bz2
cd ..
SRC="tbs/linux-tbs-drivers/v4l"
DST="drivers/media/dvb/frontends"
ARCH="x86" # Change to "x86_64" if you're running 64 bit
cp $SRC/tbs6921fe_driver.o.$ARCH $DST/tbs6921fe_driver.o
cp $SRC/tbs6980fe_driver.o.$ARCH $DST/tbs6980fe_driver.o
cp $SRC/tbs6981fe_driver.o.$ARCH $DST/tbs6981fe_driver.o


Then just run make and make install or whatever you need.

NB The patch for 2.6.39 includes a mod to i2c.h which is needed to maintain struct layout compatibility with TBS's binary only FE drivers - a sad consequence of the fact that the TBS sources are not open.

HTH

Forgot to mention that after downloading the patch you need to apply it with:

Code: Select All Code

patch -p1 < tbs698x-2.6.38.patch

substitute tbs698x-2.6.39.patch for linux 2.6.39

[JeroenM]

Thank you very much!
i´ll give that a shot.

Hi Lawrence!
I am sorry to say it did not work for me.
I followed your instructions and did not receive any errors but after reboot tvheadend did not start and dmesg outputs the below.
I can see that i now indeed have 5 adapters in /dev/dvb which i didn´t have before.
Do you have any idéas?

Hm, After reading your instructions i realized the tbs-drivers we copied out of the tbs-drivers-package needs to be put somewhere..
I dumped them in media_build/linux/ and tried to: make install but it doesn´t help either...
I really think my lack of linux-skills is preventing this to work..
I really apreciate you trying to help me out here.

If you are using the v4l media_build tree (not a plain linux source tree) then you need to change the installation slightly.

Code: Select All Code

cd media_build
DRVR="linux-tbs-drivers_110806.rar"
wget http://www.tbsdtv.com/download/common/$DRVR
mkdir tbs && cd tbs
unrar x ../$DRVR
tar -axf linux-tbs-drivers.tar.bz2
cd ..
SRC="tbs/linux-tbs-drivers/v4l"
DST="v4l"
ARCH="x86" # "x86_64" for 64-bit systems
cp $SRC/tbs6921fe_driver.o.$ARCH $DST/tbs6921fe_driver.o
cp $SRC/tbs6980fe_driver.o.$ARCH $DST/tbs6980fe_driver.o
cp $SRC/tbs6981fe_driver.o.$ARCH $DST/tbs6981fe_driver.o

This will put the TBS drivers into the correct place in the v4l tree.

NB you can't use the v4l media_build tree for Linux 2.6.39 and later because the binary TBS drivers assume the layout of the struct i2c_adapter which changed in this version. Unfortunately it's defined in "include/linux/i2c.h", which is part of the system headers, and so is not replaced by the media tree. For 2.6.39 and later you must rebuild the whole kernel after applying the patch. Please could someone convince TBS to release the source to the FE drivers to avoid this nonsense.

Great!
I use Kernel 2.6.38-8 so i should be pretty safe doing this then.
I´ll try again. I tried all different ways this morning to no avail.

I am a bit confused where to put the patch and when to actually run it.

To use the patch:

Code: Select All Code

cd media_build
wget http://www.softsystem.co.uk/download/tbs/tbs698x-2.6.38.patch
cd media
patch -p1 < ../tbs698x-2.6.38.patch

Then run install the TBS drivers and then run make.

[JeroenM]

Hi!
Sorry to bother you again..

To use the patch:

Code: Select All Code

cd media_build
wget http://www.softsystem.co.uk/download/tbs/tbs698x-2.6.38.patch
[b]cd media[/b]
patch -p1 < ../tbs698x-2.6.38.patch

Then run install the TBS drivers and then run make.

I don´t have a media directory under media_build, I do have one under "media_build/linux/drivers/" though.
I ran the patch in that directory but some parts of the patch failed.
And when running make from media_build directory i get:
