Date: Wed, 6 May 2020 16:58:48 -0700 From: Sean Christopherson <sean.j.christopherson@...el.com> To: Paolo Bonzini <pbonzini@...hat.com> Cc: Sean Christopherson <sean.j.christopherson@...el.com>, Vitaly Kuznetsov <vkuznets@...hat.com>, Wanpeng Li <wanpengli@...cent.com>, Jim Mattson <jmattson@...gle.com>, Joerg Roedel <joro@...tes.org>, kvm@...r.kernel.org, linux-kernel@...r.kernel.org Subject: [PATCH 0/2] KVM: nVMX: Skip IPBP on nested VMCS switch Or as Jim would say, "Really skip IPBP on nested VMCS switch" :-D Patch 1 is the delta between kvm/queue and v3 of the original patch[*], i.e. I just cherry-picked v3 and fixed the conflicts. Patch 2 applies the "no IPBP" logic to copy_vmcs02_to_vmcs12_rare(). Feel free to sqaush both of these to commit 7407a52f23732 ("KVM: nVMX: Skip IBPB when switching between vmcs01 and vmcs02") if you so desire.
