# WSL2+ Kernel V6.6 Howto for Windows 11 Version 6.6.36.3 09/15/2024 https://rbconnect.eu/kb/wsl2-kernel-v6-howto-for-windows-11/
# Instructions for building an x86_64 WSL2 kernel with an Ubuntu distribution (Howto uses Ubuntu 24.04 LTS) are as follows:
For testing you can Download the precompiled Kernel Image from here: https://download.rbconnect.eu/dl/Public/wsl2-linux-kernel-6-windows/
# Ubuntu 24.04 LTS Requirements
Open a WSL terminal window and launch the Distro of your choice. Install the required packages to build the kernel:
sudo apt update && sudo apt install build-essential flex bison cpio sudo dwarves libssl-dev libelf-dev bc python3 pahole python3
wget https://github.com/microsoft/WSL2-Linux-Kernel/archive/refs/tags/linux-msft-wsl-6.6.87.2.tar.gz
# Unzip it and Change directory to the kernel source code:
cd WSL2-Linux-Kernel-linux-msft-wsl-6.6.87.2
# Build the Kernel (takes some time) !! You will be asked for the following !!:
Mitigations for CPU vulnerabilities (CPU_MITIGATIONS) [Y/n/?] (NEW) Y <- (choose "n" for better Performance, but less Security Infos: https://docs.kernel.org/admin-guide/hw-vuln/mds.html#:~:text=SMT%20state%20unknown-,Mitigation%20mechanism,a%20kernel%20command%20line%20option. )
Analog Devices Generic AXI ADC IP core driver (ADI_AXI_ADC) [N/m/?] N <- (https://cateee.net/lkddb/web-lkddb/ADI_AXI_ADC.html)
make -j$(nproc) KCONFIG_CONFIG=Microsoft/config-wsl
# Install the kernel modules and headers:
sudo make modules_install headers_install
# Installing the Kernel:
# Copy the kernel image to the Windows file system:
sudo cp arch/x86/boot/bzImage /mnt/c/kernel/bzimage_6.6.36.6
# Open Windows Explorer copy the kernel from the “c:\kernel” folder to the root of C:\
(Windows security confirmation could be required).
Exit the WSL terminal window.
# Using the Kernel
# You can configure WSL to use it instead of the stock kernel as follows.
Create or edit the file `%USERPROFILE%\.wslconfig` with the following content:
[wsl2]
Kernel=C:\\kernel\\bzImage_6.6.36.6
# Open a PowerShell terminal window as Administrator and Stop the WSL instance:
wsl --shutdown
# Now you can now launch your WSL2 Distro and check the kernel version as follows:
Open a WSL terminal window and launch the Distro of your choice. Check the kernel version:
uname -r
# You should see the following output:
