这是内核自带的文档,讲解ARM芯片的内存是如何布局的!比较简单,对于初学者可以看一下!但要想深入理解Linux内存管理,建议还是找几本好书看看,如深入理解Linux虚拟内存,嵌入系统分析,Linux内核分析及程序设计等: Kernel Memory Layout on ARM Linux Linux在ARM平台上的内存布局 Russell King <rmk@arm.linux.org.uk> November 17, 2005 (2.6.15) This document de
原文:Linux内存管理:ARM Memory Layout以及mmu配置 在内核进行page初始化以及mmu配置之前,首先需要知道整个memory map. 1. ARM Memory Layout PAGE_OFFSET Start address of Kernel space 0xC000_0000 lowmem Kernel direct-mapped RAM region (1:1 mapping) Maximum 896M HIGH_MEMORY End address
Memory Layout for Multiple and Virtual Inheritance(By Edsko de Vries, January 2006)Warning. This article is rather technical and assumes a good knowledge of C++ and some assembly language.In this article we explain the object layout implemented by gc
