Exercising the Driver's I/O Controls
In this chapter, you will extend the very simple prototype driver you developed in the previous chapter. The driver you will develop in this chapter displays data read from kernel memory. The first version of this driver writes data to a system log every time the driver is loaded. The second version of this driver displays data at user request. In the third version of this driver, the user can write new data to the device.
