Subject: [PATCH v5 00/12] KVM: nVMX: Enlightened VMCS for Hyper-V on KVM
Date: Thu, 13 Sep 2018 19:05:10 +0200 [thread overview]
Message-ID: <20180913170522.24876-1-vkuznets@redhat.com> (raw)
Changes since v4:
- Rebase.
- Adjust nested state migration support after additional testing.
- Enhance self-test.
- Drop "KVM: selftests: compile against local uapi headers" patch,
add "tools/headers: update kvm.h" instead.
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).
