Linux内核剖析之进程地址空间（三）

本节主要讲述缺页异常处理程序和堆的管理等内容。缺页异常处理程序触发缺页异常程序的两种情况： 1. 由编程错误引起的异常（如访问越界，地址不属于进程地址空间）。 2. 地址属于线性地址空间，但内核还未分配相应的物理页，导致缺页异常。缺页异常处理程序总体方案：线性区描述符可以...

Linux内核剖析之进程地址空间（二）

//接前一章，本节主要介绍线性区以及相关线性区的操作。线性区 Linux通过类型为vm_area_struct的对象实现线性区。 vm_area_struct： struct vm_area_struct { struct mm_struct * vm_mm; /* The address spa...
