Technical requirements

Throughout this chapter, we'll need whatever we used in Chapter 1, Installing the Development System, and Chapter 2, A Peek Inside the Kernel, so please refer to them for cross-compilation, kernel modules loading and management, and so on. 

For more information on this chapter please read the Appendix.
