XNU 是一个混合操作系统内核，结合了微内核架构和用于系统服务的单体层。它为操作系统开发提供了基础，结合了标准化的系统调用接口、模块化设备驱动程序框架和强制访问控制安全。 该架构具有基于 Mach 的微内核和基于 BSD 的单体层。它利用消息传递进程间通信总线在隔离的内核组件和用户空间进程之间进行安全数据交换，以及将硬件特定逻辑与核心内核解耦的面向对象驱动程序框架。 该系统包括用于策略驱动安全执行的强制访问控制引擎，以及用于检查实时内存和分析系统崩溃的远程内核调试器。附加能力涵盖多处理器调度、硬件资源协调以及用于跨不同架构生成可引导镜像的构建系统。 该项目提供用于内核构建管理、调试符号生成的工具，以及用于系统调用验证的框架。

This is the official documentation repository for Raspberry Pi hardware and software. It covers the complete range of Raspberry Pi single-board computers, the RP-series microcontrollers, and the Raspberry Pi operating system. The documentation provides reference material for setting up devices, configuring hardware, and using the system for tasks including AI inference, camera and video capture, embedded development, and remote access. The documentation covers the full boot chain from the GPU firmware and EEPROM bootloader through to kernel loading, with detailed guidance on boot configuratio

XNU is an operating system kernel designed to manage system hardware and process execution across different processor architectures. It utilizes a hybrid microkernel design that combines microkernel message passing with monolithic kernel performance by embedding critical subsystems into a single address space. The project implements a port-based asynchronous messaging system for communication between kernel tasks and userspace processes. It manages hardware interactions through a layered driver architecture and enforces system-wide security policies via a mandatory access control interface.
