In this chapter, we covered in detail the hardware and software requirements to set up an appropriate development environment for beginning to work on Linux kernel development. In addition, we mentioned the basics and provided links, wherever appropriate, for setting up a Raspberry Pi device, installing powerful tools such as QEMU and a cross toolchain, and so on. We also threw some light on other "miscellaneous" tools and projects that you, as a budding kernel and/or device driver developer, might find useful, as well as information on how to begin looking up kernel documentation.
In this book, we definitely recommend and expect you to try out and work on kernel code in a hands-on fashion. To do so, you must have a proper kernel workspace environment set up, which we have successfully done in this chapter.
Now that our environment is ready, let's move on and explore the brave world of Linux kernel development! The next two chapters will teach you how to download, extract, configure, and build a Linux kernel from source.
