How to Install Kernel 5.17 From Source on openSUSE

Installing

5. 5. Configuring Kernel

   So now to Configure openSUSE Linux Custom Kernel
   First, access the Kernel Source with:

   cd linux*

   Then copy the current Configuration File into the New Kernel Source:

   sudo find /boot/ \( -iname "*config*" -a -iname "*`uname -r`*" \) -exec cp -i -t ./ {} \;

   mv *`uname -r`* .config

   In case of a Chrooted System instead yuo may look up the available Kernels with:

   ls /boot | grep config

   The grep Command refine the output List showing only the entries Matching the Keyword.
   Again if needed then fix the Configuration File editing it with nano and commenting out the Line like:

   sudo nano .config

   Use Ctrl+w to search for “CONFIG_MODULE_SIG_KEY” on nano.
   And comment out like:

   #CONFIG_MODULE_SIG_KEY

   Ctrl+x to Save & Exit.
   Else to make a Custom one then reconfigure the Kernel (Only for advanced Users) with:

   sudo make menuconfig

   For instructions see: How to Configure a Build Kernel.

6. 6. Building Kernel

   Next to Build openSUSE Custom Linux Kernel
   Make it with:

   sudo make clean

   And then:

   sudo make rpm-pkg

   When prompted if uncertain then simply follow to hit Enter until the end.

   

   Then think to other task to follow because the process will take about a couple of Hours…
   Last, to check the builded Images play:

   sudo ls /usr/src/packages/RPMS/x86_64/ | grep kernel

   

   The Kernel Packages may be situated somewhere else, so in case see: How to Locate Files on System

7. 7. Installing Kernel

   Finally, to Install openSUSE Linux Custom Kernel
   Simply play:

   sudo su -c "zypper in /usr/src/packages/RPMS/x86_64/kernel*.rpm"

   And this setup includes also the Custom Kernel Headers that you don’t will find online…

   

   And finally reboot with:

   sudo reboot now

   Finally, you should boot into your barely new openSUSE Linux Kernel :)
   To check it run:

   uname -r

   And in case of Issue you still can choose the previous one on the GRUB Splash Screen!
