FreeBSD Device Drivers

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.

FreeBSD Device Drivers

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.

Improving the Development and Testing of Device Drivers

Writing software to interact with external devices is difficult for a variety of reasons. First, this software often executes in the operating system kernel, where a single error can cause the entire system to fail.

Improving the Development and Testing of Device Drivers

Writing software to interact with external devices is difficult for a variety of reasons. First, this software often executes in the operating system kernel, where a single error can cause the entire system to fail. Second, most major operating systems today require device drivers to be written in C, a language developed roughly 40 years ago. Third, the kernel execution environment is complex, and in some systems, constantly changing, which leads to increased development costs and unreliable code. Fourth, executing drivers requires specific device hardware, which the developer may not have available. Consequently, many Linux driver patches include the comment "compile tested only." These problems make driver development a resource- and effort-intensive endeavor. This dissertation presents two new systems that improve the process of device-driver development and testing. We first present Decaf Drivers, a system for incrementally converting existing Linux kernel drivers to Java programs in user mode. With support from program-analysis tools, Decaf separates out performance-sensitive code and generates a customized kernel interface that allows developers to move the remaining code into Java over time. On the five drivers we tested, the Decaf Drivers system achieves performance close to native kernel drivers and requires few changes to the Linux kernel. We then present three versions of SymDrive, which is a system for testing Linux and FreeBSD drivers without their devices present. The system uses symbolic execution to remove the need for device hardware. The first prototype, called SymDriveProto (SDP), allows developers to test drivers without hardware by combining traces of hardware operation with symbolic execution. The second version, SymDrive, adds three new capabilities relative to SDP and existing work. First, SymDrive uses static analysis and source-to-source transformation to greatly reduce the effort of testing a new driver. Second, SymDrive incorporates a comprehensive test framework to allow developers to check many driver correctness properties. Finally, SymDrive provides an execution-tracing tool to identify how a patch changes I/O to the device and to compare device-driver implementations. We finally discuss SymDriveCluster (SDC), which allows developers to test drivers and find bugs automatically with a cluster of machines.

Tech Tactics Money Saving Secrets

FreeBSD is a complete operating system package including the kernel with device drivers and user utilities. FreeBSD is considered extremely stable and reliable. FreeBSD development started around two years later later than Linux.

Tech Tactics   Money Saving Secrets

This book shows the reader how to save money by using free or very inexpensive devices, programs, and services in order to save money while enjoying modern technology. People pay too much money for things that can be had very cheaply or for free if one only knows where to find the goodies. This book is about how to take advantage of technology without having to pay huge sums of money to big business. The author concentrates on tips, tactics, devices, programs, and secrets that actually work. It is the hope that when a reader reads and uses just one thing learned in this book that the book will pay for itself. This books offers something for everyone from a relative beginner to the hardcore geek. This book discuss the advantages and pitfalls in using free and inexpensive inexpensive technology products. Most products discussed in this book come with no strings attached. The products that do have strings attached are pointed out, and exactly what strings are explained. There are many free products available that do the same thing as their expensive counterparts. Microsoft office can cost anywhere between one hundred and several hundred dollars. There is a free program that will do almost everything Microsoft Office will that is legally available on-line for absolutely no cost to the user. The best part is the fact that this program contains no ad-ware or spy-ware. Even though long distance telephone service is getting less expensive each year, it is still pricey compared to the free and less expensive options that are currently available for those in the know. Many people pay tens and in some cases, over one hundred dollars a month so that they can watch decent television programming. In addition to paying these high rates, they often have to put up with annoying advertisements disrupting their viewing pleasure. This book shows free and inexpensive alternatives with fewer advertisements or none at all. Other people, when their computer slows to a crawl, will take their computer to a repair shop and pay tens to hundreds of dollars getting it back up to speed. This book shows people how do it quickly and easily themselves using programs already installed on the computer or available on-line for free. Some people spend tens of dollars per computer per year to protect their computer against malicious software. This book tells how and where to go to do it for free. Many computer users spend hours of frustrating searches on the Internet looking for diagnostic and optimization tools to speed up their computers or to make the more reliable. In many cases, they will come across websites featuring products that claim to do what they want. However, once they go through the trouble of downloading, installing, and using the software, the software performs the job as advertised - at least up to a point. The software will tell them what is wrong, and will have a "fix it" or "optimize" button. When the user clicks the button, he or she will see a notice that the software must "be registered" before the action is performed. Registration usually involves the payment of money. This book will show the users which programs truly do it for free. Using this book will save the reader many hours of searching, downloading, and installing programs only to find a demand of payment. The author has done the research and legwork to find the free gems that will help the reader. This book will also show the user how to use a GPS device or application to avoid speed traps and automated ticketing cameras and where to download the required data. Saving the cost of just one ticket will cause this book to pay for itself many times over. These are just a few of many examples of money savers that can be found in this book.
