Ivthandleinterrupt -

: Peripherals such as Wi-Fi cards, high-end audio interfaces, and graphics processing units (GPUs) rely on signed miniport drivers. If a driver passes a malformed physical address to a hardware chip, the IOMMU registers it as a boundary violation.

While the IVT defined the process, modern x86 and x64 systems use a more powerful and secure structure called the , which operates in protected mode . The IDT provides a more detailed "gateway" for interrupts, as each IDT entry contains not just the address but also: ivthandleinterrupt
