[PATCH 0/5] KVM: SVM: nSVM: Implement Enlightened MSR-Bitmap for Hyper-V-on-KVM and fix it for KVM-on-Hyper-V

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Enlightened MSR-Bitmap feature implements a PV protocol for L0 and L1
hypervisors to collaborate and skip unneeded updates to MSR-Bitmap.
KVM implements the feature for KVM-on-Hyper-V but it seems there was
a flaw in the implementation and the feature may not be fully functional.
PATCHes 1-2 fix the problem. The rest of the series implements the same
feature for Hyper-V-on-KVM.

Vitaly Kuznetsov (5):
  KVM: SVM: Drop stale comment from
    svm_hv_vmcb_dirty_nested_enlightenments()
  KVM: SVM: hyper-v: Enable Enlightened MSR-Bitmap support for real
  KVM: nSVM: Track whether changes in L0 require MSR bitmap for L2 to be
    rebuilt
  KVM: x86: Make kvm_hv_hypercall_enabled() static inline
  KVM: nSVM: Implement Enlightened MSR-Bitmap feature
