New Kernel for Conexant cx24120/cx24118 dvbs


Hi everyone
I had already opened a Thread but I think I need to compile new Kernel for my Ubuntu Linux 64-bit System.But I never compile any Kernel.That's why I opened new Thread.

https://www.linuxquestions.org/quest...bs-4175621112/

Code:
$ uname -a
Linux whynot-Bus 4.13.0-21-generic #24-Ubuntu SMP Mon Dec 18 17:29:16 UTC 2017 x86_64 x86_64 x86_64 GNU/Linux

https://github.com/pboettch/linux/tree/cx24120-v2

like that is it right?Or I need to use just only for Ubuntu different commands.
Code:
xz -cd linux-4.13.0-21.tar.xz | tar xvf -

xz -cd ../patch-4.13.0-21 | patch -p1

cd linux

make mrproper

Thanks

The commands are the same for all systems. If you want to use the git tree you mention, you can also download the whole of it (git clone <link to the repo>) or apply the patch as you do in your example commands.

Then I'd do something like
Code:
cd linux
cp /boot/config-4.13* .config

# regenerate the config file based on your currently running system
make olddefconfig

make linux modules

sudo make install

Can you please explain more precisely?
Code:
:/usr/src/linux-source-4.13.0$ ls
debian  debian.master  linux-source-4.13.0.tar.bz2
Code:
:/usr/src/linux-source-4.13.0$sudo su
:/usr/src/linux-source-4.13.0#  xz -cd linux-source-4.13.0.tar.bz2 | tar xjf -
xz: linux-source-4.13.0.tar.bz2: File format not recognized

bzip2: Compressed file ends unexpectedly;
	perhaps it is corrupted?  *Possible* reason follows.
bzip2: Inappropriate ioctl for device
	Input file = (stdin), output file = (stdout)

It is possible that the compressed file(s) have become corrupted.
You can use the -tvv option to test integrity of such files.

You can use the `bzip2recover' program to attempt to recover
data from undamaged sections of corrupted files.

tar: Child returned status 2
tar: Error is not recoverable: exiting now
Code:
:/usr/src/linux-source-4.13.0#  xz -cd linux-source-4.13.0.tar.bz2 | tar xvf -
xz: linux-source-4.13.0.tar.bz2: File format not recognized
tar: This does not look like a tar archive
tar: Exiting with failure status due to previous errors

For tar.bz2,
Code:
$ tar jxvf file.tar.bz2
No xz.

Could you please explain us in more details what do you want to do? I didn't understand it very well. Do you want to add the cx2...c drivers to the latest kernel? Or enable some drivers that you're missing?
