This project is a technical reference and educational guide focused on the internal architecture of the Linux kernel. It serves as a low-level systems programming resource and documentation for operating system internals, detailing the implementation of core mechanisms within the kernel source code. The materials provide a detailed study of the Linux kernel, tracing behavior through actual C source and assembly. It specifically covers the progression from the bootloader and decompression to the final kernel entry point, alongside the management of hardware interrupts and symmetric multiproces

This project is an educational resource for developing bare-metal operating systems and kernels from scratch on Raspberry Pi hardware. It provides a structured guide to systems programming using the Rust language, focusing on the implementation of core kernel components that execute directly on ARM-based hardware without the support of an underlying operating system or standard library. The tutorials emphasize a modular architecture that separates hardware-independent kernel logic from processor-specific and board-specific configurations. By utilizing a hardware abstraction layer and distinct

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

embedded-notes هي مجموعة من أدلة الدراسة التقنية وملاحظات التطوير التي تركز على Linux المضمن، وداخلية نواة Linux، وبرمجة C. تعمل كمرجع لتطوير الأنظمة المضمنة ومورد تحضيري للمقابلات التقنية في هذا المجال. يوفر المشروع وثائق مفصلة حول كتابة برامج تشغيل الأجهزة، وإدارة الذاكرة الافتراضية، وفهم داخلية النواة. كما يتضمن أدلة حول بروتوكولات شبكة IoT، مثل MQTT وTCP/IP، ويحدد التفاصيل المعمارية لهياكل الرقائق والأجهزة الطرفية. تغطي المادة سطحاً واسعاً من برمجة الأنظمة، بما في ذلك إدارة الذاكرة اليدوية، وإدارة دورة حياة العمليات، وتنفيذ مفاهيم نظام التشغيل في الوقت الفعلي. كما تتضمن مراجع للأدوات منخفضة المستوى، مثل التجميع المتقاطع لـ ARM، وتحليل الثنائيات، وكتابة نصوص shell لأتمتة البناء.

This project is a pure-Rust bootloader and firmware loader designed for x86 operating system development. It initializes bare-metal hardware and loads compiled operating system kernels from both legacy BIOS and modern UEFI firmware environments into a running state. The software utilizes a dual-firmware boot architecture and a pure-rust low-level runtime to handle hardware initialization and memory management without relying on standard library runtimes. It provides automated disk image packaging to combine compiled kernels and bootloader binaries into ready-to-boot FAT-formatted disk images
