KVM SVM changes for 6.4. The highlight, by a country mile, is support for virtual NMIs. The following changes since commit d8708b80fa0e6e21bc0c9e7276ad0bccef73b6e7: KVM: Change return type of kvm_arch_vm_ioctl() to "int" (2023-03-16 10:18:07 -0400) are available in the Git repository at: https://github.com/kvm-x86/linux.git tags/kvm-x86-svm-6.4 for you to fetch changes up to c0d0ce9b5a851895f34fd401c9dddc70616711a4: KVM: SVM: Remove a duplicate definition of VMCB_AVIC_APIC_BAR_MASK (2023-04-04 11:08:12 -0700) ---------------------------------------------------------------- KVM SVM changes for 6.4: - Add support for virtual NMIs - Fixes for edge cases related to virtual interrupts ---------------------------------------------------------------- Maxim Levitsky (2): KVM: nSVM: Raise event on nested VM exit if L1 doesn't intercept IRQs KVM: SVM: add wrappers to enable/disable IRET interception Santosh Shukla (5): KVM: nSVM: Don't sync vmcb02 V_IRQ back to vmcb12 if KVM (L0) is intercepting VINTR KVM: nSVM: Disable intercept of VINTR if saved L1 host RFLAGS.IF is 0 KVM: SVM: Add definitions for new bits in VMCB::int_ctrl related to vNMI KVM: x86: Add support for SVM's Virtual NMI KVM: nSVM: Implement support for nested VNMI Sean Christopherson (5): KVM: x86: Raise an event request when processing NMIs if an NMI is pending KVM: x86: Tweak the code and comment related to handling concurrent NMIs KVM: x86: Save/restore all NMIs when multiple NMIs are pending x86/cpufeatures: Redefine synthetic virtual NMI bit as AMD's "real" vNMI KVM: x86: Route pending NMIs from userspace through process_nmi() Xinghui Li (1): KVM: SVM: Remove a duplicate definition of VMCB_AVIC_APIC_BAR_MASK arch/x86/include/asm/cpufeatures.h | 8 +- arch/x86/include/asm/kvm-x86-ops.h | 2 + arch/x86/include/asm/kvm_host.h | 11 ++- arch/x86/include/asm/svm.h | 10 ++- arch/x86/kvm/svm/nested.c | 91 ++++++++++++++++++---- arch/x86/kvm/svm/svm.c | 153 ++++++++++++++++++++++++++++++------- arch/x86/kvm/svm/svm.h | 29 +++++++ arch/x86/kvm/x86.c | 46 +++++++++-- 8 files changed, 292 insertions(+), 58 deletions(-)
