Subject: [Qemu-devel] [PATCH v2 0/2] i386/kvm: add support for Hyper-V Enlightened VMCS
Date: Mon, 22 Oct 2018 18:55:04 +0200 [thread overview]
Message-ID: <20181022165506.30332-1-vkuznets@redhat.com> (raw)
Changes since v1 [Roman Kagan]:
- Throw away HV_CPUID_MIN_NESTED.
- Create zeroed 0x40000006-0x40000009 CPUID leaves.
Hyper-V Enlightened VMCS feature was merged to KVM, enable it in Qemu.
The feature gives us a significant performance boost for Hyper-V on KVM
deployments.
The first patch of the series is posted for completeness only.
