Technical requirements

During this chapter, we need kernel sources we already downloaded in the Configuring and building the kernel recipe in Chapter 1, Installing the Development System, and, of course, we also need our cross-compiler installed, as seen in the Setting up the host machine recipe in Chapter 1, Installing the Development System. The code and other files used in this chapter can be downloaded from GitHub at https://github.com/giometti/linux_device_driver_development_cookbook/tree/master/chapter_02.
