In this chapter, you will be presented with information on the real-time component of the Yocto Project. Also, in the same context, a short discussion regarding the general purpose of an operating system and a real-time operating system will be explained. We will then move toward the PREEMPT_RT patches that try to change normal Linux into a full powered real-time operating system; we will try to look at it from more angles and at the end, sum it up and draw a conclusion out of it. This is not all, any real-time operation needs its applications, so a short presentation on the do's and don'ts of application writing that is suitable in the context of a real-time operating system, will also be presented. Keeping all of this in mind, I believe it's time to proceed with this chapter content; I hope you enjoy it.

You will find a more detailed explanation of real-time components in this chapter. Also, the relation between Linux and real-time will be shown to you. As everyone...
