Subject: [PATCH v2 08/13] KVM: VMX: optimize APIC ID read with APICv
Date: Thu, 7 Jul 2016 19:15:45 +0200 [thread overview]
Message-ID: <20160707171550.14675-9-rkrcmar@redhat.com> (raw)
In-Reply-To: <20160707171550.14675-1-rkrcmar@redhat.com>
The register is in hardware-compatible format now, so there is not need
to intercept.
