This project is a bare-metal operating system developed for ARM64 architecture. It serves as a low-level implementation of kernel engineering, focusing on the fundamental construction of an OS from the hardware level up. The system is distinguished by its comprehensive approach to ARM64 processor control, featuring a red-black tree task scheduler and a hierarchical page table system for virtual memory management. It implements a sophisticated privilege model that handles transitions between kernel and user modes, ensuring process isolation through address space splitting and exception level m

xv6 is a Unix-like educational operating system designed for teaching kernel concepts. It is implemented as an instructional kernel for x86 and RISC-V architectures, featuring a virtual memory manager and support for symmetric multiprocessing. The system is designed to demonstrate core OS principles through a simplified re-implementation of Unix Version 6. It provides a controlled environment for studying system calls, trap handling, and process lifecycles. Its capability surface covers process management, including scheduling and context switching, and memory management via page tables for

This project is a Go library and runtime for loading and managing eBPF programs and maps. It provides a bytecode loader and kernel interface to inject instructions into kernel hooks for system-level execution and observability across both Linux and Windows operating systems. The library features a relocation engine and tooling to ensure program compatibility across different kernel versions and distributions. It supports portable deployment by embedding compiled objects for multiple CPU architectures into a single binary and provides the ability to load signed system drivers on Windows. The

30dayMakeOS is an educational hobby operating system project designed for the x86 architecture. It implements a monolithic kernel and a custom bootloader that transitions the CPU from real mode to 32-bit protected mode to enable flat memory addressing. The project focuses on low-level system development, featuring a custom graphics driver for direct pixel-buffer rendering and window management without an existing operating system. It includes an x86 bootloader that loads the kernel from disk into memory. The system covers core kernel capabilities including round-robin task scheduling for pro

NuttX est un système d'exploitation temps réel (RTOS) conforme à POSIX, conçu pour les microcontrôleurs allant des architectures 8 bits aux 64 bits. Il fournit un environnement d'exécution déterministe avec un ordonnanceur de tâches temps réel et un noyau embarqué POSIX pour assurer une exécution de code portable sur diverses cibles matérielles. Le projet se distingue par une couche d'abstraction matérielle complète qui fournit des pilotes standardisés pour I2C, SPI, CAN et USB sur divers chipsets de semi-conducteurs. Il dispose également d'une pile réseau embarquée prenant en charge TCP, UDP, IPv4 et IPv6, ainsi que des protocoles industriels tels que Modbus et DroneCAN. Le système couvre un large éventail de capacités, incluant une gestion avancée de la mémoire avec pagination à la demande, des opérations cryptographiques sécurisées et un système de fichiers virtuel pour gérer des types de stockage disparates. Il intègre en outre des interfaces de haut niveau pour les interfaces graphiques, la synthèse audio et l'exécution de plusieurs langages de script et charges de travail WebAssembly. L'environnement est construit en utilisant Make ou CMake pour cibler des configurations de cartes et des chipsets spécifiques.
