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.
APICv support in KVM is split into 5 patches:
0001-x86-apicv-add-APICv-register-virtualization-support.patch - enable APICv register virtualization
0002-x86-apicv-adjust-for-virtual-interrupt-delivery.patch - add basic KVM frameowrk for virtual interrupt delivery
0003-x86-apicv-enable-virtual-interrupt-delivery-for-VMX.patch - enable APICv virtual interrupt delivery
0004-x86-apicv-add-interface-for-poking-EOI-exit-bitmap.patch - EOI exit bitmap handling
0005-x86-apicv-add-virtual-x2apic-support.patch - handle MSR style in virtual x2apic
Apply them in above order
APICv is disabled by default, and use below command to enable it:
modprobe enable_apicv_reg=1 enable_apicv_vid=1

Please use git send-email in the future for correct threading of the

I don't see patches for enabling posted interrupts? This can improve
both assigned and virtual interrupt delivery.

OK, We will use git send-email to send out the v2 patch

We will have a separate patch for posted interrupts after cleaning up this patch. Meanwhile it is not ready.

Please post it together with these patches, even if it is incomplete. I
would like to have a view of the direction.
