Kaiwan N. Billimoria

Kaiwan N. Billimoria taught himself BASIC programming on his dad's IBM PC back in 1983. He was programming in C and Assembly on DOS until he discovered the joys of Unix, and by around 1997, Linux! Kaiwan has worked on many aspects of the Linux system programming stack, including Bash scripting, system programming in C, kernel internals, device drivers, and embedded Linux work. He has actively worked on several commercial/FOSS projects. His contributions include drivers to the mainline Linux OS and many smaller projects hosted on GitHub. His Linux passion feeds well into his passion for teaching these topics to engineers, which he has done for well over two decades now. He's also the author of Hands-On System Programming with Linux, Linux Kernel Programming (and its Part 2 book) and Linux Kernel Debugging. It doesn't hurt that he is a recreational ultrarunner too.

Learning about the CPU scheduling internals – part 1 – essential background

Let’s take a quick look at the essential background information we require to understand CPU scheduling on Linux.

Note that, in this book, we do not intend to cover material that competent (user space) system programmers on Linux should already be well aware of; this includes basics such as process (or thread) states, basic information on what real time is, the POSIX scheduling policies, and so on. This (and more) has been covered in some detail in my earlier book, Hands-On System Programming with Linux, published by Packt in October 2018. Nevertheless, we do touch upon some of the basics here.

What is the KSE on Linux?

As you learned in Chapter 6, Kernel Internals Essentials – Processes and Threads, in the Organizing processes, threads, and their stacks – user and kernel space section, every (user mode) thread alive on the system is bestowed with...
