Subject: [PATCH v3 08/14] KVM: VMX: optimize APIC ID read with APICv
Date: Tue, 12 Jul 2016 22:09:24 +0200 [thread overview]
Message-ID: <20160712200930.32143-9-rkrcmar@redhat.com> (raw)
In-Reply-To: <20160712200930.32143-1-rkrcmar@redhat.com>
The register is in hardware-compatible format now, so there is not need
to intercept.
