Summary

In this chapter, we have demystified character devices, and we have seen how to let users interact with our driver through device files. We learned how to expose file operations to user space and control their behavior from within the kernel. We went so far that you are even able to implement multi-device support.

The next chapter is a bit more hardware-oriented, as it deals with the device tree, a mechanism that allows hardware devices present on the system to be declared to the kernel. See you in the next chapter.
