TBS6281 linux driver install

Post by Sidders » Mon Sep 19, 2022 7:52 pm

I'm trying to rebuild my Mythbox after a hdd failure about a year ago. Apart from a new hdd all the hw is exactly the same. I did a fresh install of Ubuntu 22.04.1 and now I'm having a nightmare getting the TV card drivers installed. I've tried to the open source and closed source with no luck. I can post more details but knowing what details to post would be helpful to start with. Did something change that I don't know about?

I have the older TBS6280 and a TBS6981.

I use the drivers from https://github.com/tbsdtv/media_build it fairly straight forward to set up and use but it is a pain to have to manually update the drivers after each kernel update :(

Thanks - I'm used to having to update the drivers after each OS update so that's not a problem. I just need to get them setup for starters. Are there any step-by-step instructions for getting these working?

From memory so apologies if I forget something but it goes something like this.

1. install build-essential which installs some tools required to build from source code like gcc and make

Code: Select all

sudo apt install build-essential
2. install git used to download and maintain source code repositories (don't think build-essential installs this?)

Code: Select all

sudo apt install git
3. change directory to where you want to save the git repo then use git to get the media_build source code repository

Code: Select all

cd ~
git clone https://github.com/tbsdtv/media_build.git
4. change into the media_build directory and build the new kernel modules

Code: Select all

cd media_build
./build
The build script should tell you if you have any missing dependencies if it does just use apt to install them and try again.
5. Finally if the build completed OK install the new kernel modules then reboot

Code: Select all

sudo make install
sudo reboot
If at a later date you install a new kernel then you need to rebuild the modules
1. change into the media_build source code repo and update it

Code: Select all

cd ~/media_build
git pull

2. now rebuild the modules

Code: Select all

./build
If the build fails then you may have to clean the source code to rebuild from fresh

Code: Select all

make distclean
then try the ./build command again

3. once built OK install the new modules and reboot

Code: Select all

sudo make unstall
sudo reboot


It's important to note the modules will be built for the running kernel so after you use apt to update the kernel you must then reboot so you are running the new kernel before you try to rebuild the modules.

I tried and all went well until running the build script. Output below. I'm not sure where the problems lie - a bit beyond my understanding. Any help gratefully received.

Preparing to compile for kernel version 5.15.0

***WARNING:*** You do not have the full kernel sources installed.
This does not prevent you from building the v4l-dvb tree if you have the
kernel headers, but the full kernel source may be required in order to use
make menuconfig / xconfig / qconfig.

If you are experiencing problems building the v4l-dvb tree, please try
building against a vanilla kernel before reporting a bug.

Vanilla kernels are available at http://kernel.org.
On most distros, this will compile a newly downloaded kernel:

cp /boot/config-`uname -r` <your kernel dir>/.config
cd <your kernel dir>
make all modules_install install

Please see your distro's web site for instructions to build a new kernel.

WARNING: This is the V4L/DVB backport tree, with experimental drivers
	 backported to run on legacy kernels from the development tree at:
		http://git.linuxtv.org/media-tree.git.
	 It is generally safe to use it for testing a new driver or
	 feature, but its usage on production environments is risky.
	 Don't use it in production. You've been warned.

Do you have the kernel headers installed? This should show you if you have or not

Code: Select all

apt-cache policy linux-headers-`uname -r`

Did the kernel get updated between you trying to build the modules and you doing the apt-cache policy test?
One shows 5.15.0-47-generic and the other 5.15.0-48-generic

I would try rebooting (doesn't look like it's needed but just in case) and try again to build the modules but this time do a make distclean first just to be sure.

Code: Select all

cd ~/media_build
make distclean
./build
sudo make install
I just updated a server to 5.15.0-48-generic and everything rebuild OK also on 22.04LTS. Everything from my build looks very similar to yours including the git error and the no kernel sources warning but it still compiles and installs the modules just fine.

That was more successful. I had updated the kernel between the build and policy test.
I get the required

Code: Select all

Kernel modules: saa716x_tbs_dvb
line in the usual

Code: Select all

lspci
check, but mythbackend doesn't pick up the tuner when I try to set it up.

I would paste the install script output but it's too large to be accepted here and I can't figure out how to add/share large files.

I do get lots of complaints about

Code: Select all

unavailability of vmlinux
during the build...

If you look at the output sudo dmesg does it look like the card is recognized and initialized OK?

For my 6280 I see this among other stuff
SAA716x Budget 0000:0b:00.0: DVB: registering adapter 0 frontend 0 (TurboSight TBS 6280 DVB-T/T2/C)...

Ah, the only output I get from a sudo dmesg is many multiple lines of the following:
[xxxxx.yyyyyy] Lockdown: systemd-logind: hibernation is restricted: see man kernel-lockdown.7

OK, so turning off the UEFI boot in the BIOS helped and I do indeed see a line like yours above. That also seemed to unblock the rest of the problem and I can now see the cards in mythbackend setup. Onwards to configuration. Thanks for all the help. Appreciated.
