Linux Kernel Module Cheat

Dieses Projekt bietet eine Linux-Kernel-Entwicklungsumgebung und eine System-Emulations-Suite für das Erstellen und Debuggen von Kernel-Modulen und Bare-Metal-Assembly über mehrere Hardware-Architekturen hinweg. Es fungiert als umfassende Sandbox und Framework für Low-Level-Systementwicklung und nutzt QEMU, um Hardware-Umgebungen ohne physische Geräte zu simulieren.

Die Umgebung integriert Cross-Compilation-Toolchains unter Verwendung von Buildroot und crosstool-NG, um x86_64-, ARMv7- und ARMv8-Plattformen von einem einzigen Host aus anzusteuern. Sie bietet ein spezialisiertes Kernel-Debugging-Framework, das GDB und KGDB für die schrittweise Ausführung und Zustandsinspektion von Kernel- und Userland-Prozessen nutzt.

Zu den breiten Funktionen gehören automatisierte Regressionstests zur Isolierung von Boot- und Funktionsfehlern durch Versionskontroll-Bisection, Hardware-Abstraktion für das Management von CPU-Energiezuständen und Systemregistern sowie Low-Level-Testprimitive für Speicherzustandsintegrität und Assembly-Analyse. Das System enthält zudem Utilities für Performance-Benchmarking von Befehlen, Output-Logging und containerisiertes Workspace-Bootstrapping.
