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 este un sistem de operare în timp real (RTOS) compatibil POSIX, conceput pentru microcontrolere de la arhitecturi pe 8 biți până la 64 de biți. Oferă un mediu de execuție determinist cu un scheduler de task-uri în timp real și un kernel embedded POSIX pentru a asigura execuția portabilă a codului pe diverse ținte hardware. Proiectul se distinge printr-un strat de abstractizare hardware cuprinzător care oferă drivere standardizate pentru I2C, SPI, CAN și USB pe diverse chipset-uri semiconductoare. De asemenea, dispune de un stack de rețea embedded care suportă TCP, UDP, IPv4 și IPv6, alături de protocoale industriale precum Modbus și DroneCAN. Sistemul acoperă o gamă largă de capabilități, inclusiv gestionarea avansată a memoriei cu paginare la cerere, operațiuni criptografice securizate și un sistem de fișiere virtual pentru gestionarea tipurilor de stocare disparate. De asemenea, integrează interfețe de nivel înalt pentru interfețe grafice (GUI), sinteză audio și execuția mai multor limbaje de scripting și workload-uri WebAssembly. Mediul este construit folosind Make sau CMake pentru a viza configurații specifice de plăci și chipset-uri.
