Santosh Shukla 1c4522ab13 KVM: SVM: Add definitions for new bits in VMCB::int_ctrl related to vNMI ... Add defines for three new bits in VMVC::int_ctrl that are part of SVM's Virtual NMI (vNMI) support: V_NMI_PENDING_MASK(11) - Virtual NMI is pending V_NMI_BLOCKING_MASK(12) - Virtual NMI is masked V_NMI_ENABLE_MASK(26) - Enable NMI virtualization To "inject" an NMI, the hypervisor (KVM) sets V_NMI_PENDING. When the CPU services the pending vNMI, hardware clears V_NMI_PENDING and sets V_NMI_BLOCKING, e.g. to indicate that the vCPU is handling an NMI. Hardware clears V_NMI_BLOCKING upon successful execution of IRET, or if a VM-Exit occurs while delivering the virtual NMI.
