    The Linux kernel is the foundation of almost every operating system in the Ubuntu Linux family, including CentOS and Fedora.

    In most cases, you don’t need to round the kernel as it is set by default Optional when installing the operating system. Also, with a major kernel update, your organization may use yum time or apt-get to update the kernel on your Linux system.

    However, you may encounter certain conditions under which you may be in the market for compiling a kernel from source. Below are some situations in which you may want to compile the kernel on your Linux system.

  • To enable experimental features that probably won’t be included by default in one of our cores.
  • To enable support for a new hardware component that is not currently supported by the standard kernel process.
  • To debug each of our kernels
  • Or just to see if the kernel is ok, you can look at some kernel source and compile the software yourself. This
  • In this tutorial, we will see how to compile the Linux kernel from source.

    Also note that even if you only want to compile the full driver, you don’t need to compilecore. All you need is the generic Linux-headers kernel package.

    1. Download The Latest Kernel

    The most stable way is to download the latest reliable kernel from kernel.org.

    # cd /usr/src/#wget https://www.kernel.org/pub/linux/kernel/v3.x/linux-3.9.3.tar.xz

    2. Extract Kernel Source

    The second step is to unzip the kernel source file for compilation.

    #black-xvJf linux-3.9.3.tar.xz

    3. Customize Kernel Core

    They contain almost 3000 configuration options. In general, in order to be able to use the kernel used by most people on most hardware, Linux distributions such as Ubuntu, Fedora, Debian, RedHat, CentOS, etc. will include support for the most popular hardware. You can make any configuration from the distribution type and in addition to your company that can add their own settings, or you can configure this kernel from scratch, or you can start from the default configuration provided by its kernel.

    # cd linux-3.9.3#Menu configuration

    Be make menu configuration launches another text-based user interface with optionsThe default build frame, as shown in the icon. You must have the libncurses and libncurses-devel packages installed to order this for best performance.

    We will use the Go Delinquent configuration provided by the kernel. So select “Save” and save the configuration throughout the file as “.config”.

    CONFIG_MMU=yCONFIG_NEED_DMA_MAP_STATE=jCONFIG_NEED_SG_DMA_LENGTH=jCONFIG_GENERIC_ISA_DMA=jCONFIG_GENERIC_BUG=yCONFIG_GENERIC_HWEIGHT=y

    4. Compile The Entire Linux Kernel

    Create #
    # Create modules
    # Go to module_install

    At this point, you should see a directory called /lib/modules/3.9.3/ on your home system.

    5. Install A New Kernel

    # install provider

    The make install command creates the following files in the /boot directory.

  • vmlinuz-3.9.3 – current kernel
  • System.map-3.9.3 Symbols – exported by this kernel
  • initrd.img-3.9.- 3 The initrd image is a temporary kernel filesystem used during boot
  • config-3.9.3 – core file
  • The make install configuration manager also updates this grub.cfg file by default. Therefore, most users do not need to manually edit the grub .cfg file.

    6.Load Linux Into The Kernel

    To use the new kernel that most of you have just compiled, reboot your system.

    # reload

    Because grub.cfg adds kernel substitution as the default boot, this system will reboot with a full kernel. If you’re having trouble with your family’s new kernel, you can select the old kernel you don’t need from the Grub menu during the tutorial and use your install as normal.

    After the system boots, use the uname command to check which system is running the new Linux kernel.

    $ uname -r3.9.3

    The Linux kernel is the foundation of Unix-like operating systems. The kernel is responsible for the communication between the computer hardware and software, as well as allocating resources for searching.

    All Linux distributions are based on some pre-installed kernel. But if you want to disable a few options and truck drivers, or try experimental fixes, you need to build a Linux kernel.

    In this valuable step-by-step guide, you will learn how to create and compile a Linux kernel from scratch.

    • Linux running system
    • Terminal/command line access
    • User has sudo/root privileges
    • 12 GB free disk space

    Building The Linux Kernel

    The Linux kernel build process consists of seven simple steps. However, the procedure is known to take a long time, mainly depending on the speed of the system.

    Follow the strategies below to build the most recent Linux kernel at the time this article was published. If

    Note: The version on the kernel website does not match the steps we are going to use, use these commands, replacing the actual kernel version number.

    Step 1. Download: Source Code

    1. Visit an authoritative kernel website and download the latest kernel. The downloaded file contains compressed source code.

    2. Open the station and use the wget command to download the Linux kernel which provides https://cdncode:

    wget.kernel.org/pub/linux/kernel/v5.x/linux-5.9.6.tar.xz

    Excerpt From Step 2: Source Code

    When the file is ready, run the exact tar command to extract the source codee:
