The perfect emulation setup to study and develop the Linux kernel v5.9.2, kernel modules, QEMU, gem5 and x86_64, ARMv7 and ARMv8 userland and baremetal assembly, ANSI C, C++ and POSIX. EVERYTHING is built from source. GDB step debug and KGDB just work. Powered by Buildroot and crosstool-NG. Highly automated. Thoroughly documented. Automated tests. "Tested" in an Ubuntu 20.04 host.
TL;DR: Section 2.2.1, “QEMU Buildroot setup getting started” tested on Ubuntu 24.04:
git clone https://github.com/cirosantilli/linux-kernel-module-cheat cd linux-kernel-module-cheat sudo apt install docker python3 -m venv .venv . .venv/bin/activate ./setup ./run-docker create ./run-docker sh
This leaves you inside a Docker shell. Then inside Docker:
./build --download-dependencies qemu-buildroot ./run
and you are now in a Linux userland shell running on QEMU with everything built fully from source.
