The ideas discussed here are demonstrated by way of a couple of modified versions of the scull driver. We finish with a look at how to implement a few different device access policies within drivers. Then we proceed to various ways of synchronizing with user space by the end of this chapter you have a good idea of how to put processes to sleep (and wake them up), implement nonblocking I/O, and inform user space when your devices are available for reading or writing. We start with implementing the ioctl system call, which is a common interface used for device control. This chapter examines a few concepts that you need to understand to write fully featured char device drivers. Now that we're equipped with debugging tools should something go awry-and a firm understanding of concurrency issues to help keep things from going awry-we can safely go ahead and create a more advanced driver. But a real device usually offers more functionality than synchronous read and write. In Chapter 3, we built a complete device driver that the user can write to and read from.
