Detailed Description

ACPI IRQ resource descriptor.

Note

The actual IRQ resource descriptor may contain an additional byte at the end depending on if the length field in the header is 2 or 3. To maintain type safety we do not include this byte in the structure. Instead use the ACPI_IRQ_DESCRIPTOR_INFO() macro to access it if needed.
