  • Servicing interrupts generated responsive to actuation of hardware, via dynamic incorporation of ACPI functionality into virtual firmware
    Patent number: 8650565
    Abstract: The methods and systems described herein describe methods and systems for forwarding an interrupt that is generated by hardware to virtual firmware executing on a virtual machine. A control program receives an interrupt generated by hardware connected to the computing device. The control program forwards the interrupt to virtual firmware executed by a virtual machine executed by the processor of the computing device. The virtual machine receives the interrupt from the virtual firmware and requests, of the virtual firmware by the virtual machine and responsive to receiving the interrupt, objects and methods associated with the interrupt. The control program receives from the virtual firmware, the request for objects and methods associated with the interrupt. The control program extracts, from an ACPI of firmware of the computing device, objects and methods associated with the interrupt and forwards the extracted objects and methods to the virtual machine.
