Also, device drivers are much easier to implement as part of the kernel; such drivers would have complete access to the data structures and other routines in the kernel and could call them freely. A conglomerate kernel containing all drivers in this manner presents several problems. First of all, it requires the system administrator to rebuild the kernel in order to selectively include device drivers, as we saw in the previous section.
The cooperative nature of the Linux kernel development compounds this problem, and not all parts of the code are as neatly contained as they should be. There's also live online events, interactive content, certification prep materials, and more. Explore a preview version of Linux Device Drivers right now. This book is for anyone who wants to support computer peripherals under the Linux operating system or who wants to develop new hardware and run it under Linux. Linux is the fastest-growing segment of the UNIX market and is winning over enthusiastic adherents in many application areas.
This book reveals information that heretofore has been passed by word-of-mouth or in cryptic source code comments, showing how to write a driver for a wide range of devices. Classes of Devices and ModulesThe Linux way of looking at devices distinguishes between three fundamental device types. Each module usually With an understanding of peripheral buses in place, we can take a detailed look at the Linux device Oftencount is one, but there If you are working on a driver for an input device, thisoption may be helpful When devices Upload a Thing!
