Today, a programmer who wants to comprehend how the Linux VM functions are essentially forced to study the kernel source code line-by-line, which is an arduous and time-consuming effort.
This book devotes itself to thoroughly describing how Linux's memory management is built, reducing the learning curve from months to only a few short weeks. The Linux VM is the Linux kernel's most significant individual component. The performance of the entire system is significantly impacted by the behavior of the VM, which has an impact on all other kernel subsystems.
This book is special in that it not only goes into unprecedented detail about the Linux VM itself but also provides its theoretical underpinnings of it, which are interesting to both developers and students but have been left out of recent Linux kernel-related literature. It is divided into three sections. An explanation of how to approach reading an open source project's code opens in the first section. The VM architecture is then thoroughly described, complete with multiple diagrams and call graphs, making it suited for those who need a thorough understanding of how the VM works. A line-by-line breakdown of the C source modules (source code commentary) that implement the VM is provided in the second section.
