Driver Structure Overview

Figure 3-1 shows data structures and routines that may define the structure of a character or block device driver. Such drivers typically include a device loadable driver section, device configuration section, and device access section.

Figure 3-1 Device Driver Roadmap

The first two sections in Figure 3-1 are discussed in Chapter 5, Autoconfiguration; the third section is discussed in Chapter 9, Drivers for Character Devices and Chapter 10, Drivers for Block Devices.
