  • Lazy handling of end of interrupt messages in a virtualized environment
    Patent number: 8103815
    Abstract: Techniques enable reducing a number of intercepts performed by a hypervisor by reducing a number of End Of Interrupt (EOI) messages sent from a virtual central processing unit (CPU) to a virtual advanced programmable interrupt controller (APIC). The EOI path of the guest operating system running on the virtual CPU is altered to leave a marker indicating that the EOI has occurred. At some later time the hypervisor inspects the marker and lazily updates the virtual APIC state.
