27 * The flat IRQ space is divided into two regions:
28 * 1. A one-to-one mapping of real physical IRQs. This space is only used
29 * if we have physical device-access privilege. This region is at the
30 * start of the IRQ space so that existing device drivers do not need
31 * to be modified to translate physical IRQ numbers into our IRQ space.
32 * 3. A dynamic mapping of inter-domain and Xen-sourced virtual IRQs. These
33 * are bound using the provided bind/unbind functions.
