A few minor fixes and cleanups, along with feature "enabling" for flush-by-ASID to play nice with newer versions of VMware Workstation that require it. The following changes since commit e9e60c82fe391d04db55a91c733df4a017c28b2f: selftests/kvm: fix compilation on non-x86_64 platforms (2023-11-21 11:58:25 -0500) are available in the Git repository at: https://github.com/kvm-x86/linux.git tags/kvm-x86-svm-6.8 for you to fetch changes up to 72046d0a077a8f70d4d1e5bdeed324c1a310da8c: KVM: SVM: Don't intercept IRET when injecting NMI and vNMI is enabled (2023-11-30 12:51:22 -0800) ---------------------------------------------------------------- KVM SVM changes for 6.8: - Revert a bogus, made-up nested SVM consistency check for TLB_CONTROL. - Advertise flush-by-ASID support for nSVM unconditionally, as KVM always flushes on nested transitions, i.e. always satisfies flush requests. This allows running bleeding edge versions of VMware Workstation on top of KVM. - Sanity check that the CPU supports flush-by-ASID when enabling SEV support. - Fix a benign NMI virtualization bug where KVM would unnecessarily intercept IRET when manually injecting an NMI, e.g. when KVM pends an NMI and injects a second, "simultaneous" NMI. ---------------------------------------------------------------- Sean Christopherson (4): Revert "nSVM: Check for reserved encodings of TLB_CONTROL in nested VMCB" KVM: nSVM: Advertise support for flush-by-ASID KVM: SVM: Explicitly require FLUSHBYASID to enable SEV support KVM: SVM: Don't intercept IRET when injecting NMI and vNMI is enabled arch/x86/kvm/svm/nested.c | 15 --------------- arch/x86/kvm/svm/sev.c | 7 +++++-- arch/x86/kvm/svm/svm.c | 18 ++++++++++++++++-- 3 files changed, 21 insertions(+), 19 deletions(-)
