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 the 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 hardware-oriented since it deals with platform drivers, which expose hardware device capabilities to the user space. The power of character drivers combined with platform drivers is just amazing. See you in the next chapter.
