Summary

Now, IRQ multiplexing has no more secrets from you. We have discussed the most important element of IRQ management in Linux systems: the IRQ domain API. You have the basics to understand existing interrupt controller drivers, as well as their binding from within the DT. IRQ propagation has been discussed in order to explore what happens between the request and the handler invocation.

In the next chapter, we deal with a completely different topic: the Linux device model.
