O'Reilly Releases "Understanding the Linux Kernel, Third Edition"
The book is not specifically for system administrators or programmers, but for anyone who wants to understand how things really work inside the machine. "It explains the theoretical underpinnings for why Linux, and many other operating systems, do things the way they do," Cesati explains. "We try to go beyond superficial features and offer a background, such as the history of major features and why they were used."
"Understanding the Linux Kernel" differs from other books on Linux internals by discussing the kernel in relation to a specific hardware platform. "Efficient kernels take advantage of most available hardware features, such as addressing techniques, caches, processor exceptions, special instructions, processor control registers, and so on," Bovet points out. "If we want to convince readers that the kernel indeed does quite a good job in performing a specific task, we must first tell what kind of support comes from the hardware."
