Subject: [PATCH v6 00/13] KVM: nVMX: Enlightened VMCS for Hyper-V on KVM
Date:   Tue, 16 Oct 2018 18:49:58 +0200
Message-Id: <20181016165011.6607-1-vkuznets@redhat.com>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

Changes since v5:
- Rebase to kvm/queue.
- Add "KVM: selftests: state_test: test bare VMXON migration" patch.

Original description:

This is an initial implementation of Enlightened VMCS for nested Hyper-V on
KVM. Using it helps to spare 1500 cpu cycles for nested vmexit (tight cpuid
loop in WS2016 with Hyper-V role on KVM: 15200 cycles -> 13700 cycles).
