Next, clone the latest version of the Linux kernel source code from GitHub or any other repository hosting service to a local directory on your system. 3. Verify that the downloaded files are authentic and have not been tampered with using GPG signatures or other verification methods. 4. Extract the contents of the archive into a new folder, which will serve as the working directory for building and compiling the kernel modules. 5. Navigate to the newly created folder and run “make oldconfig” to update your current configuration file based on any new options added since your distribution’s last release. This step is optional if you have already configured your kernel using a previous version of devscripts suite or manually. 6. Modify the configuration as needed by navigating to each option using the up/down arrow keys and pressing until you reach the Help menu, which provides more information about that particular option. Once you have configured it to your liking, press again until you see Save at the bottom of the screen, then hit Enter twice (without changing the filename) to save your changes to .config. 7. To build only certain targets such as vmlinux or modules, specify them using make followed by the target name. For example: “make bzImage” for x86_64 architecture or “make Image.gz” for AArch64 and RISC-V architectures. 8. Clean up any unnecessary files with “make clean” to remove almost everything except .config file, or use “mrproper” to delete the .config file as well. For a more thorough cleanup, use “distclean” which removes all patch files too. 9. To install out-of-tree modules like ZFS or Nvidia DKMS, or write your own modules, you will need the header files provided by the Linux kernel source code.
Compiling custom kernels with devscripts suite is a straightforward process that involves downloading and verifying the latest version of the Linux kernel source code from GitHub or any other repository hosting service, extracting it into a new folder on your system, running “make oldconfig” to update your current configuration file based on any new options added since your distribution’s last release, modifying the configuration as needed using the up/down arrow keys and pressing until you reach the Help menu for each option, saving changes to .config by hitting Enter twice (without changing the filename), building only certain targets such as vmlinux or modules using make followed by the target name, cleaning up any unnecessary files with “make clean” or “mrproper”, and installing out-of-tree modules like ZFS or Nvidia DKMS or writing your own modules.
