Subject: [PATCH 0/2] KVM: SEV: Fix a CR8 intercept goof with SEV-ES guests
Date: Tue, 10 Mar 2026 14:18:39 -0700 [thread overview]
Message-ID: <20260310211841.2552361-1-seanjc@google.com> (raw)
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
