This article describes the most important concepts related to the Linux kernel’s interrupt handling mechanisms.

A clear understanding of the Linux kernel’s interrupt handling mechanism is essential if you are to write solid, reusable device interrupt handlers. It is also mandatory if you are to successfully port Linux to custom hardware.

Bill Gatliff provides a walkthrough of the portions of the Linux kernel that manage interrupts and describes how Linux interacts with interrupt controllers and how to adapt code for custom hardware.

Interrupt handling is a fundamental part of the Linux kernel. Most of the kernel’s functionality, in particular the parts of interest to embedded developers, in some way involve interrupt handling.
