Device drivers make it possible for your software to communicate with your hardware, and because every operating system has specific requirements, driver writing is nontrivial. When developing for FreeBSD, you've probably had to scour the Internet and dig through the kernel sources to figure out how to write the drivers you need. Thankfully, that stops now. In FreeBSD Device Drivers, Joseph Kong will teach you how to master everything from the basics of building and running loadable kernel modules to more complicated topics like thread synchronization. After a crash course in the different FreeBSD driver frameworks, extensive tutorial sections dissect real-world drivers like the parallel port printer driver. You'll learn: –All about Newbus, the infrastructure used by FreeBSD to manage the hardware devices on your system –How to work with ISA, PCI, USB, and other buses –The best ways to control and communicate with the hardware devices from user space –How to use Direct Memory Access (DMA) for maximum system performance –The inner workings of the virtual null modem terminal driver, the USB printer driver, the Intel PCI Gigabit Ethernet adapter driver, and other important drivers –How to use Common Access Method (CAM) to manage host bus adapters (HBAs) Concise descriptions and extensive annotations walk you through the many code examples. Don't waste time searching man pages or digging through the kernel sources to figure out how to make that arcane bit of hardware work with your system. FreeBSD Device Drivers gives you the framework that you need to write any driver you want, now.

Mac OS X was released in March 2001, but many components, such as Mach and BSD, are considerably older. Understanding the design, implementation, and workings of Mac OS X requires examination of several technologies that differ in their age, origins, philosophies, and roles. Mac OS X Internals: A Systems Approach is the first book that dissects the internals of the system, presenting a detailed picture that grows incrementally as you read. For example, you will learn the roles of the firmware, the bootloader, the Mach and BSD kernel components (including the process, virtual memory, IPC, and file system layers), the object-oriented I/O Kit driver framework, user libraries, and other core pieces of software. You will learn how these pieces connect and work internally, where they originated, and how they evolved. The book also covers several key areas of the Intel-based Macintosh computers. A solid understanding of system internals is immensely useful in design, development, and debugging for programmers of various skill levels. System programmers can use the book as a reference and to construct a better picture of how the core system works. Application programmers can gain a deeper understanding of how their applications interact with the system. System administrators and power users can use the book to harness the power of the rich environment offered by Mac OS X. Finally, members of the Windows, Linux, BSD, and other Unix communities will find the book valuable in comparing and contrasting Mac OS X with their respective systems. Mac OS X Internals focuses on the technical aspects of OS X and is so full of extremely useful information and programming examples that it will definitely become a mandatory tool for every Mac OS X programmer.

PREFACE The internals of the UNIX kernel are fairly well-documented, most notably by Goodheart and Cox 10, Bach 1, McKusick et al. 19, and Vahalia 39. These texts have become a common source of reference information for those who want to better understand the internals of UNIX. However little has been written about the specifics of the Solaris kernel. The paucity of Solaris specific information led us to create our own reference material. As we published information through white papers, magazine columns, and tutorials, the number of folks expressing interest motivated us to produce a complete work that discussed Solaris exclusively. About This Book This book is about the internals of Sun's Solaris Operating Environment. The rapid growth of Solaris has created a large number of users, software developers, systems administrators, performance analysts, and other members of the technical community, all of whom require in-depth knowledge about the environment in which they work. Since the focus of this book is the internals of the Solaris kernel, the book provides a great deal of information on the architecture of the kernel and the major data structures and algorithms implemented in the operating system. However, rather than approach the subject matter from a purely academic point of view, we wrote the book with an eye on the practical application of the information contained herein. Thus, we have emphasized the methods and tools that can be used on a Solaris system to extract information that otherwise is not easily accessible with the standard bundled commands and utilities. We want to illustrate how you can apply this knowledge in a meaningful way, as your job or interest dictates. To maximize the usefulness of the text, we included specific information on Solaris versions 2.5.1, 2.6, and Solaris 7. We cover the major Solaris subsystems, including memory management, process management, threads, files, and file systems. We do not cover details of low-level I/O, device drivers, STREAMS, and networking. For reference material on these topics, see "Writing Device Drivers" 28, the "STREAMS Programming Guide" 29, and "UNIX Network Programming" 32. The material included in this book is not necessarily presented at an introductory level, although whenever possible we begin discussing a topic with some conceptual background information. We assume that you have some familiarity with operating systems concepts and have used a UNIX-based operating system. Some knowledge of the C programming language is useful but not required. Because of the variety of hardware platforms on which Solaris runs, it is not practical to discuss the low-level details of all the different processors and architectures, so our hardware focus, when detail is required, is admittedly UltraSPARC-centric. This approach makes the most sense since it represents the current technology and addresses the largest installed base. In general, the concepts put forth when detail is required apply to other processors and platforms supported. The differences are in the specific implementation details, such as per-processor hardware registers. Throughout the book we refer to specific kernel functions by name as we describe the flow of various code segments. These routines are internal to the operating system and should not be construed as, or confused with, the public interfaces that ship as part of the Solaris product line-the systems calls and library interfaces. The functions referenced throughout the text, unless explicitly noted, are private to the kernel and not callable or in any way usable by application programs. Intended Audience We hope that this book will serve as a useful reference for a variety of technical staff members working with the Solaris Operating Environment. Application developerscan find information in this book about how Solaris implements functions behind the application programming interfaces. This information helps developers understand performance, scalability, and implementation specifics of each interface when they develop Solaris applications. The system overview section and sections on scheduling, interprocess communication, and file system behavior should be the most useful sections. Device driver and kernel module developersof drivers, STREAMS modules, loadable system calls, etc., can find herein the general architecture and implementation theory of the Solaris Operating Environment. The Solaris kernel framework and facilities portions of the book (especially the locking and synchronization primitives chapters) are particularly relevant. Systems administrators, systems analysts, database administrators, and ERP managersresponsible for performance tuning and capacity planning can learn about the behavioral characteristics of the major Solaris subsystems. The file system caching and memory management chapters provide a great deal of information about how Solaris behaves in real-world environments. The algorithms behind Solaris tunable parameters (which are detailed in Appendix A) are covered in depth throughout the book. Technical support staffresponsible for the diagnosis, debugging, and support of Solaris will find a wealth of information about implementation details of Solaris. Major data structures and data flow diagrams are provided in each chapter to aid debugging and navigation of Solaris Systems. System users who just want to know moreabout how the Solaris kernel works will find high-level overviews at the start of each chapter. In addition to the various technical staff members listed above, we also believe that members of the academic community will find the book of value in studying how a volume, production kernel implements major subsystems and solves the problems inherent in operating systems development. How This Book Is Organized We organizedSolaras Internalsinto several logical parts, each part grouping several chapters containing related information. Our goal was to provide a building block approach to the material, where later sections build on information provided in earlier chapters. However, for readers familiar with particular aspects of operating systems design and implementation, the individual parts and chapters can stand on their own in terms of the subject matter they cover. Part One:Introduction to Solaris Internals Chapter 1— An Introduction to Solaris Chapter 2— Kernel Services Chapter 3— Kernel Synchronization Primitives Chapter 4— Kernel Bootstrap and Initialization Part Two:The Solaris Memory System Chapter 5— Solaris Memory Architecture Chapter 6— Kernel Memory Chapter 7— Memory Monitoring Part Three:Threads, Processes, and IPC Chapter 8— The Solaris Multithreaded Process Architecture Chapter 9— The Solaris Kernel Dispatcher Chapter 10— Interprocess Communication Part Four:Files and File Systems Chapter 11— Solaris Files and File I/O Chapter 12— File System Overview Chapter 13— File System Framework Chapter 14— The UNIX File System Chapter 15— Solaris File System Cache Solaris Source Code In February 2000, Sun announced the availability of Solaris source. This book provides the essential companion to the Solaris source and can be used as a guide to the Solaris kernel framework and architecture. It should also be noted that the source available from Sun is the Solaris 8 source. Although this book covers Solaris versions up to and including Solaris 7, almost all of the material is relevant to Solaris 8. Updates and Related Material To complement this book, we created a Web site where we will place updated material, tools we refer to, and links to related material on the topics covered. The Web site is available at http://www.solarisinternals.com. A Note from the Authors We certainly hope that you get as much out of reading Solaris Internals as we did from writing it. We welcome comments, suggestions, and questions from readers.

In the world of Unix operating systems, the various BSDs come with a long heritage of high-quality software and well-designed solutions, making them a favorite OS of a wide range of users. Among budget-minded users who adopted BSD early on to developers of some of today's largest Internet sites, the popularity of BSD systems continues to grow. If you use the BSD operating system, then you know that the secret of its success is not just in its price tag: practical, reliable, extraordinarily stable and flexible, BSD also offers plenty of fertile ground for creative, time-saving tweaks and tricks, and yes, even the chance to have some fun."Fun?" you ask. Perhaps "fun" wasn't covered in the manual that taught you to install BSD and administer it effectively. But BSD Hacks, the latest in O'Reilly's popular Hacks series, offers a unique set of practical tips, tricks, tools--and even fun--for administrators and power users of BSD systems.BSD Hacks takes a creative approach to saving time and getting more done, with fewer resources. You'll take advantage of the tools and concepts that make the world's top Unix users more productive. Rather than spending hours with a dry technical document learning what switches go with a command, you'll learn concrete, practical uses for that command.The book begins with hacks to customize the user environment. You'll learn how to be more productive in the command line, timesaving tips for setting user-defaults, how to automate long commands, and save long sessions for later review. Other hacks in the book are grouped in the following areas: Customizing the User Environment Dealing with Files and Filesystems The Boot and Login Environments Backing Up Networking Hacks Securing the System Going Beyond the Basics Keeping Up-to-Date Grokking BSD If you want more than your average BSD user--you want to explore and experiment, unearth shortcuts, create useful tools, and come up with fun things to try on your own--BSD Hacks is a must-have. This book will turn regular users into power users and system administrators into super system administrators.
