The interrupt code rests on hardware behavior that the code cannot show on its own: how GIN, the GPU's interrupt controller, records and delivers interrupts, what edge-triggered delivery requires of a handler, and how the GSP signals the CPU. Some of those requirements come from OpenRM rather than from the hardware manuals. Add a design document that records that behavior, the rules that nova-core follows because of it, and the terms that the code uses for it. The code comments cite the document by section rather than repeating it.
