Device drivers use the interfaces and data structures written by the kernel developers to implement device control and IO. A very good kernel programmer may not know a lot about interrupt latency and hardware determinism, but she will know a lot about how locks, queues, and Kobjects work. Pre-requisites. In order to develop Linux device drivers, it is necessary to have an understanding of the following: C programming. Some in-depth knowledge of C programming is needed, like pointer usage, bit manipulating functions, etc. Microprocessor programming. A device driver is a computer program which interacts with real hardware components. For example, the computer which you use now to read this web page has a device driver for the display monitor. Another example is the disk driver, which reads and writes raw data from disk(s) in your computer. Clearly, computer systems would be useless without good device drivers.
