example 1: 特理地址和虚拟地址一致 Physical addressing mode requires no page tables and the CPU does not attempt to perform any address translations in this mode. The Linux kernel is linked to run in physical address space. example 2 : 内核代码在高端内存当中,用户代码在低端内存当中. p…
Computer Systems A Programmer's Perspective Second Edition The main memory of a computer system is organized as an array of M contiguousbyte-sized cells. Each byte has a unique physical address (PA). The first byte hasan address of 0, the next byte an…

在了解虚拟文件系统之前,必须先知道什么是 Kernal Space 与 User Space. Kernal Space 与User Space 的差别,在于内存使用上安全机制的差异. kernal执行时会占据一段系统的内存空间, 这一段内存空间便是Kernal Space. 所有用户是无法和kernal space 直接交互的. 在/proc/iomem文件中所记录的kernal地址, 可以在命令行中执行: cat /proc/iomem | more User S…
Vitrual Memory In order to manage memory more efficiently and with fewer errors, modern systems provide an abstraction of main memory known as virtual memory (VM). Virtual memory is an elegant interaction of hardware exceptions, hardware ad-dress tra…
