17,518Vezi pe GitHubThis project is a freestanding kernel written in Rust that boots on x86 hardware without a standard library. It serves as a low-level system implementation focusing on the creation of a bare metal operating system. The system implements a bootable disk image toolchain that transforms source code into binaries compatible with a bootloader. It features a custom memory allocator for dynamic memory management and an x86 kernel implementation that includes paging, interrupt handling, and VGA text mode. The project covers several core capability areas, including low-level memory management through

6,783Vezi pe GitHubToaruOS is an independent operating system built from the ground up without external dependencies. It features a custom x86-64 kernel that supports symmetric multiprocessing and paging, paired with a graphical windowing system and a dedicated bytecode interpreter for application logic. The system distinguishes itself by integrating an embedded Python environment for system-level development and a custom graphical interface that handles its own window composition and text rendering. It includes a compatibility layer for third-party application support and a system package manager for handling

5,306Vezi pe GitHubAcest proiect este o colecție de sisteme de operare minimale, bootloadere și drivere hardware utilizate pentru a demonstra programarea de nivel jos x86 și interfațarea hardware. Servește drept toolkit de dezvoltare a kernel-ului și laborator de programare de sistem conceput pentru testarea conceptelor de arhitectură și a comportamentului hardware într-un emulator de sistem. Repository-ul oferă implementări de referință pentru crearea de imagini de disc bootabile și încărcarea etapelor kernel-ului. Include ghiduri pentru implementarea tranzițiilor în modul protejat, paginarea memoriei, tabelele descriptorilor de întrerupere și multiprocesarea simetrică pe hardware x86. Codebase-ul acoperă o gamă largă de primitive de sistem, inclusiv maparea memoriei virtuale, gestionarea întreruperilor hardware și detectarea memoriei fizice. Conține, de asemenea, drivere bare-metal pentru difuzorul PC, tastatura PS/2, porturile seriale și bufferele de text VGA. Proiectul include un toolchain binar brut pentru a compila sursa de asamblare în imagini pentru execuție hardware directă și suportă testarea prin emulare hardware și debugging la distanță.
