include vpicd.inc mov eax, IRQHand ; IRQ handle mov ebx, VM ; current VM handle call VID_EOI_Proc |
The VID_EOI_Proc procedure handles the end of an interrupt. The system calls this procedure whenever a hardware interrupt handler in the virtual machine issues an EOI. The procedure typically calls the VPICD_Clear_Int_Request and VPICD_Phys_EOI services to clear the virtual interrupt and end the physical interrupt.
The system disables interrupts before calling this procedure. The procedure can re-enable interrupts if necessary.
IRQHand
Specifies the handle for the interrupt request.
VM
Specifies the handle of the current virtual machine.
This procedure has no return value.
This procedure is typically used by a virtual device, such as the virtual mouse device, that lets a corresponding MS-DOS driver process hardware interrupts. The virtual device reflects the interrupt to the virtual machine that owns the mouse.
The MS-DOS driver services the interrupt, and issues issues an EOI. At this point, the system calls the VID_EOI_Proc procedure.
This procedure may modify the EAX, EBX, ECX, EDX, ESI, and Flags registers.
