Appendix C describes seq files, a kernel helper interface introduced in the 2.6 kernel that device drivers can use to monitor and trend data points. The book is generally organized according to device and bus complexity, coupled with practical reasons of dependencies between chapters. So, we start off with basic device classes such as character, serial, and input. Next, we look at simple serial buses such as I2C and SMBus. External I/O buses such as PCMCIA, PCI, and USB follow. Video, audio, block, and network devices usually interface with the processor via these I/O buses, so we look at them soon after. The next portions of the book are oriented towards embedded Linux, and cover technologies such as wireless networking and flash memory. User space drivers are discussed towards the end of the book. Kernel Version This book is generally up to date as of the 2.6.23/2.6.24 kernel versions. Most code listings in this book have been tested on a 2.6.23 kernel. If you are using a later version, look at Linux websites such as lwn.net to learn about the kernel changes since 2.6.23/24. Conventions Used Source code, function names, and shell commands, are written like this. The shell prompt used is bash>.
