[PATCH 0/2] KVM: SEV: Fix a CR8 intercept goof with SEV-ES guests

Posted by Sean Christopherson 4 weeks ago

Fix a recently introduced bug where KVM incorrectly enables CR8 write
interception when inhibiting AVIC for SEV-ES guests, and extend the SEV+
smoke selftest to guard against similar goofs in the future.

Sean Christopherson (2):
  KVM: SEV: Don't set CR8 write intercept when disabling AVIC for SEV-ES
    guests
  KVM: selftests: Verify SEV+ guests can read and write EFER, CR0, CR4,
    and CR8
