Xen devel - Sep 2012 - [ PATCH v2 0/3] xen: enable APIC-Register Virtualization, Virtual-interrupt delivery and add virtual x2apic support

The VMCS includes controls that enable the virtualization of interrupts and the
Advanced Programmable Interrupt Controller (APIC).
When these controls are used, the processor will emulate many accesses to the
APIC, track the state of the virtual APIC, and deliver virtual interrupts - all
in VMX non-root operation without a VM exit.
You can refer to Chapter 29 of the latest SDM.
This series of patches enable APIC-Register Virtualization and Virtual-interrupt
delivery.

PATCH 1/3: Enable APIC-Register Virtualization.

PATCH 2/3: Enable Virtual-interrupt delivery.

PATCH 3/3: Add virtual x2apic support

Hi Jan and Keir,
For the APICV patch, do you have any more comment?

Best regards,
Li Jiongxi

Keir applied the three patches already, and they even came out of
staging already.
