linux-kernel-module-cheat is a comprehensive emulation and development environment for studying and developing the Linux kernel, kernel modules, and low-level system code across multiple architectures.
The project addresses the challenge of setting up a working environment for kernel development and learning by automating the entire toolchain configuration. It bundles Buildroot and crosstool-NG to handle cross-compilation, QEMU for emulation, and GDB with KGDB support for step-level debugging. The approach eliminates manual configuration of build systems, bootloaders, and debugging infrastructure by providing a pre-integrated setup that handles x86_64, ARMv7, and ARMv8 targets. Users can write and test kernel modules, baremetal assembly, and userland code in C, C++, and POSIX without wrestling with toolchain incompatibilities.
The tool suits developers and students who want to learn kernel internals or develop kernel modules without maintaining their own build infrastructure. It is particularly valuable for those exploring multiple architectures or needing reliable GDB and KGDB debugging without manual setup. The project includes automated tests and extensive documentation, making it accessible to learners while supporting serious development work. It targets Ubuntu hosts and handles the full stack from bootloader through userland, distinguishing it from minimal kernel build guides or architecture-specific tutorials.
The project maintains thorough documentation covering the entire system. Automated testing is integrated into the workflow. The codebase is actively maintained with attention to compatibility across different host environments.
