宏内核与微内核架构概述 本文概述了两种内核类型：微内核和宏内核。尽管本文主要聚焦于内核，但开发人员和用户在很大程度上是 通过与操作系统的交互来体验内核的功能。诸如"哪个内核最适合我的团队或项目？"或者"我是否应该将 开发从一种内核类型迁移到另一种？"这样的问题通常在操作系统的上下文中被回答，涉及现有IP的投资以 及从一个操作系统切换到另一个操作系统的成本。Linux 是拥有宏内核的操作系统中最知名的例子，而我们的 风河开物RTOS也采用了宏内核。在风河，与汽车客户的交流中，关于哪种内核更优的讨论几乎总是围绕微内 核架构的 QNX Neutrino 实时操作系统展开。 内核通常被描述为操作系统核心中的一个进程或程序，用于管理系统硬件和软件的运行。在宏内核中，整个 操作系统作为一个程序运行在内核模式下，也就是说，内核服务和其他操作系统功能（如设备驱动程序、协 议栈和文件系统）都在同一地址空间中执行。在微内核实现中，只有最少数量的内核服务运行在内核模式 下，而所有其他操作系统功能则在用户模式和不同地址空间中执行。每种方法都有其优缺点。随着每一代的 发展，这两种类型的内核都会被不断优化，以解决各自方法的相关问题。 宏 ...
