2. Support for Intel Meteor Lake graphics is now stable and enabled by default.
3. The Nouveau driver gains support for NVIDIA’s GPU System Processor firmware, potentially improving performance and stability.
4. Linux kernel 6.7 adds support for some more upcoming hardware platforms like GC 11.5, DCN 3.5, VPE 6.1, NBIO 7.11, and DML2, support for AMD platforms with es83xx chips, as well as AMD ACP 6.3 and 7.0.
5. Updates for Intel Lunar Lake, Arrow Lake, AMD Pensando data processing units, and Sophgo RISC-V devices are also present.
6. You can now optionally disable 32-bit program support at boot time on x86-64 systems, streamlining the system for modern applications.
7. Rust support is bumped to version 1.73.0, with IBT enabled by default.
8. LoongArch architecture is now supported for Kernel-based Virtual Machine, expanding virtualization options.
9. x86 CPU microcode loading is optimized for better performance and stability.
10. DP Alt Mode 2.1 support in USB Type-C driver
11. KVM support for guest memory operation instructions on ARM platforms
12. Updated CephFS logging and support for non-contiguous capacity bitmasks for Intel’s CAT implementation
13. Thunderbolt/USB4 fixes for new hardware types and devices
14. Network support for Landlock (TCP bind and connect access control)

How To Compile And Install Kernel On Ubuntu In 2024

Download the latest version of the Kernel from the website of Linux Kernel.

sudo wget https://cdn.kernel.org/pub/linux/kernel/vx.x/linux-x.x.tar.xz

Now, Install the requirements or dependencies before compiling and installing Linux Kernel on Ubuntu.

sudo apt-get install git fakeroot build-essential ncurses-dev xz-utils libssl-dev bcflex libelf-dev bison

Now, run the following command for extracting the downloaded file.

sudo tar xvf linux-x.x.x.tar.xz

cd linux-x.xx.xx

Let us now configure our Kernel :

cp/boot/config-$(uname -r) .config

Now, execute the make menuconfig command so that you can have access to a configuration tool

make menuconfig

Now, you will see the various module in the configuration tool window. From this window, you can disable or enable the various modules.
Compiling Kernel On Ubuntu
Run the following commands to compile kernel on Ubuntu.

sudo make

Run the following command to know the number of cores available

sudo nproc

Now, you can mention the core with the make command

sudo make-j<3

The -j option is used to assign more cores to the process so that the process speeds up.
Now, Install all the modules that you enabled on the configuration tool for:

make modules_install

Install Kernel On Ubuntu

sudo make install

Run the following command to enable Kernel for a boot.

sudo update-initramfs -c -k x.xx.xx

Now update-grub

sudo update-grub

Now, reboot your Linux

sudo reboot

After restarting Ubuntu, you can run the following command to verify the new Linux Kernel version:

sudo uname -mrs
