| H A D | nested.c | diff 55714cdd Thu Apr 23 06:17:28 MDT 2020 Paolo Bonzini <pbonzini@redhat.com> KVM: nSVM: Move SMI vmexit handling to svm_check_nested_events() Unlike VMX, SVM allows a hypervisor to take a SMI vmexit without having any special SMM-monitor enablement sequence. Therefore, it has to be handled like interrupts and NMIs. Check for an unblocked SMI in svm_check_nested_events() so that pending SMIs are correctly prioritized over IRQs and NMIs when the latter events will trigger VM-Exit. Note that there is no need to test explicitly for SMI vmexits, because guests always runs outside SMM and therefore can never get an SMI while they are blocked.
