Synopsis :

Have you ever wondered why Linux is so efficient? Do you want to know if its performance will be useful for some unusual application that you have? Have you ever tried to look at the kernel source code? If you answered yes to any of these questions, this is the book for you. Understanding the Linux Kernel gives you a guided tour of the Linux kernel along with valuable and significant insights. Although Linux is often perceived as a casual hacker experiment, it has increasingly become not only a mission-critical part of many organizations, but also a sophisticated display of programming skill. It incorporates many advanced operating-system concepts and has proven itself extremely robust and efficient for a wide range of uses. After reading this book, you will understand what conditions bring out Linux's best performance and how it meets the challenge of providing good system response during process scheduling, file access, and memory management in a wide variety of environments. The authors introduce each topic by explaining its importance, and relate kernel operations to the system calls or utilities that are familiar to Unix programmers and users. Major topics include: Memory management, including file buffering, process swapping, and Direct Memory Access (DMA); The Virtual Filesystem and the Second Extended Filesystem; Process creation and scheduling; Signals, interrupts, and the essential interfaces to device drivers; Timing; Synchronization in the kernel; Interprocess Communication (IPC); Program execution

À propos de l?auteur: Daniel P. Bovet earned a Ph.D. in Computer Science at UCLA in 1968 and is now a full professor at the University of Rome "Tor Vergata," Italy. He had to wait more than 25 years before being able to teach an OS course in a proper manner, because of the unavailability of source code for modern, well-designed systems. Now, thanks to cheap PCs and to Linux, Marco and Dan are able to cover all the facets of an operating system from booting to tuning and to hand out tough, satisfying homework to their students. (These young guys working at home on their PC are really spoiled; they never had to fight with punched cards.) In fact, he was so fascinated by the accomplishments of Linus and his followers that he spent the last few years trying to unravel some of Linux's mysteries. It seemed natural after all that work to write a book about what he found out. Marco Cesati got a degree in Mathematics in 1992 and a Ph.D. in Computer Science (Univ. of Rome "La Sapienza") in 1995. He is now a research assistant in the Computer Science Department of the School of Engineering (Univ. of Rome "Tor Vergata"). In the past he was system administrator and Unix programmer for the university (as a Ph.D. student) and for several institutions (as a consultant). During the last three years he has been continuously involved in teaching his students how to change the Linux kernel in strange and funny ways.
