Learn Linux kernel programming, hands-on: a uniquely effective top-down approach

The Linux? Kernel Primer is the definitive guide to Linux kernel programming. The authors' unique top-down approach makes kernel programming easier to understand by systematically tracing functionality from user space into the kernel and carefully associating kernel internals with user-level programming fundamentals. Their approach helps you build on what you already know about Linux, gaining a deep understanding of how the kernel works and how its elements fit together.

One step at a time, the authors introduce all the tools and assembly language programming techniques required to understand kernel code and control its behavior. They compare x86 and PowerPC implementations side-by-side, illuminating cryptic functionality through carefully-annotated source code examples and realistic projects. The Linux? Kernel Primer is the first book to offer in-depth coverage of the rapidly growing PowerPC Linux development platform, and the only book to thoroughly discuss kernel configuration with the Linux build system. Coverage includes

• Data structures

• x86 and PPC assembly language

• Viewing kernel internals

• Linux process model

• User and kernel space

• Interrupts and exceptions

• Memory allocation and tracking

• Tracing subsystem behavior

• I/O interactions

• Filesystems and file operations

• Scheduling and synchronization

• Kernel boot process

• Kernel build system

• Configuration options

• Device drivers

• And more...

If you know C, this book teaches you all the skills and techniques you need to succeed with Linux kernel programming. Whether you're a systems programmer, software engineer, systems analyst, test professional, open source project contributor, or simply a Linux enthusiast, you'll find it indispensable.
