wsl-kernel-module

A simple WSL kernel module meant as a demonstration on how to develop linux kernel modules under WSL.

Version

This was developed for WSL2 Kernel 5.15.19.X but should work on all versions as long as you up/downgrade the submodule.

Please note that you might have to change the WSL submodule branch depending on your WSL instance. It should match whatever is returned when typing:

uname -r

Copy your config over:

zcat /proc/config.gz > .config

Compile the kernel:

make -j $(nproc)

Install:

sudo make -j $(nproc) modules_install

cd kernel_module
make

Congratulations, you should now have a working kernel module called main.ko. Try loading it via:

sudo insmod main.ko

and look at what it prints via:

dmesg
