Linux Kernel Module Cheat - Linux-Kernel-Modu…

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.

Asterinas is a memory-safe operating system kernel designed to prevent data races and memory corruption. It functions as a Linux-ABI compatible kernel, enabling the execution of existing Linux binaries and container workloads while providing a declarative operating system distribution model. The project distinguishes itself by acting as a virtual machine container host and a confidential computing guest OS, allowing it to run within hardware-isolated Trusted Execution Environments such as Intel TDX. It implements a minimal trusted computing base by isolating unsafe low-level operations and se

seL4 is a formally verified microkernel whose C implementation is backed by machine-checked mathematical proofs of correctness, confidentiality, integrity, and availability. It enforces strict isolation between processes through hardware-enforced address space separation and a capability-based access control system, where each process holds explicit rights only to the resources it has been granted. The kernel exposes hardware resources through a minimal API of system calls that manage threads, address spaces, and inter-process communication, with synchronous IPC supporting sender-identifying b
