Subject: [PATCH v6 10/33] KVM: nVMX: Support several new fields in eVMCSv1
Date: Tue, 30 Aug 2022 15:37:14 +0200 [thread overview]
Message-ID: <20220830133737.1539624-11-vkuznets@redhat.com> (raw)
In-Reply-To: <20220830133737.1539624-1-vkuznets@redhat.com>
Enlightened VMCS v1 definition was updated with new fields, add
support for them for Hyper-V on KVM.
Note: SSP, CET and Guest LBR features are not supported by KVM yet
and 'struct vmcs12' has no corresponding fields.
