Description: 作者：华清远见嵌入式学院。《Linux设备驱动开发详解》（08&09年度畅销榜TOP50）第11章、内存与I/O访问。由于Linux系统中提供了复杂的内存管理功能，所以内存的概念在Linux系统中变得相对复杂，出现了常规内存、高端内存、虚拟地址、逻辑地址、总线地址、物理地址、I/O内存、设备内存、预留内存等概念。本章将系统地讲解内存和I/O的访问编程，带您走出内存和I/O的概念迷宫。11.1节讲解内存和I/O的硬件机制，主要涉及内存空间、I/O空间和MMU。11.2节讲解Linux的内存管理、内存区域的分布、常规内存与高端内存的区别。11.3节讲解Linux内存存取的方法，主要涉及内存动态申请以及通过虚拟地址存取物理地址的方法。11.4节讲解设备I/O内存和I/O端口的访问流程，这一节对于编写设备驱动意义非常重大，设备驱动使用此节的方法访问物理设备。11.5节讲解设备驱动中的DMA与CACHE一致性问题以及DMA编程方法。-Author: HuaQing vision embedded institute. The Linux device driver development "(08 and 09 sep TOP50) annual list of best-selling chapter 11, the memory and I/O visit. Because of the complex Linux system provide the memory management function, so the concept of memory in Linux systems become relatively complex, the emergence of a conventional memory, the high memory, virtual address, logical address, bus address, physical address, I/O memory, equipment memory, obligate concepts such as memory. This chapter will systematically explaining memory and I/O visit programming, take you out of memory and I/O concept maze. Section 11.1 explain memory and I/O hardware mechanism, mainly involves the memory space, I/O space and MMU. Section 11.2 explain the Linux memory management, memory area distribution, conventional memory and the high memory difference. Section 11.3 memory access method explained Linux, Lord ?

Description: linux下查看硬盘坏道信息代码
对于硬盘的坏道的确没有什么好的办法，ata协议中的smart命令本意上是好的，但是很多的硬盘厂商并没有很好的实现smart的功能；硬盘的相关错误信息会存在相应的扇区里，但是这些扇区相当于一个环形的缓冲区，所以记录的错误信息有限，如果需要完整的硬盘坏道信息，smart就无能为力了。通过完整的读一遍硬盘可以找出坏道的完整信息，但是读牵涉到了DMA的数据传输过程所以效率较低；ata的协议里READ VERIFY (EXT)命令大大提高效率，该命令是NO DATA类型的
-See information under linux hard disk damage code for hard disk bad sectors really no good way, ata protocol smart command intention is good, but a lot of hard disk manufacturers do not achieve a good smart functionality hard disk related error messages exist in the corresponding sector, but these sectors is equivalent to a circular buffer, so the limited information recording error, and if necessary complete hard disk damage information, smart on the powerless. Read it through a complete hard disk bad sectors can find complete information, but reading involves the DMA data transfer process is so inefficient ata agreement in READ VERIFY (EXT) greatly improves the efficiency of command, the command is NO DATA type .
