linux arm dma This chapter delves into the area of Linux memory management, with an emphasis on techniques that are useful to the device driver writer. Many types of driver pro- gramming require some understanding of how the virtual memory subsystem works; the material we cover in this chapter comes in handy more than once as we get into some of the more complex and performance-critical subsystems. The virtual mem- ory subsystem is also a highly interesting part of the core Linux kernel and, there- fore, it merits a look.
