+//! IRQ abstractions.
+//!
+//! An IRQ is an interrupt request from a device. It is used to get the CPU's
+//! attention so it can service a hardware event in a timely manner.
+//!
+//! The current abstractions handle IRQ requests and handlers, i.e.: it allows
+//! drivers to register a handler for a given IRQ line.
