3.3.4
Building Kernel
Kernel repo link:
https://github.com/intel/linux-kernel-overlay/tree/lts2021-ubuntu
Before building the kernel, ensure these tools are installed:
sudo apt-get install flex bison kernel-wedge gcc libssl-dev
libelf-dev quilt
To build the kernel, run build.sh script and linux-headers*.deb, linux-image*.deb and
linux-libc-dev*.deb packages for Kernel to be generated in the same folder.
git clone
cd linux-kernel-overlay
git checkout lts2021-ubuntu
./build.sh
The build process depends on the resources available on the machine (factors such as
more greater CPU power and larger RAM speed up the build process). It is important to
have large amount of storage to build the kernel, and so it is recommended to have at
least 256GB of storage on the system.
For more information, refer to README.
3.3.4.1 Replacing Kernel
To overlay the Kernel, follow the steps below.
Step 1: Change to root mode:

dpkg -i linux-image-5.15.94--000_5.15.94-0_amd64.deb
dpkg -i linux-libc-dev_5.15.94-0_amd64.deb
