Technical requirements

I assume that you have gone through Online Chapter, Kernel Workspace Setup, and have appropriately prepared a guest VM (or a native system) running Ubuntu 22.04 LTS (or a later stable release) and installed all the required packages. If not, I highly recommend you do this first.

Also, the last section of this chapter deliberately runs a very memory-intensive app, so intensive that the kernel will take some drastic action (killing off some process(es))! I highly recommend you try out stuff like this on a safe, isolated system, preferably a Linux test VM (with no important data on it).

To get the most out of this book, I strongly recommend you first set up the workspace environment, including cloning this book’s GitHub repository for the code, and work on it in a hands-on fashion. The GitHub repository can be found at https://github.com/PacktPublishing/Linux-Kernel-Programming_2E.
