[Xen-devel] [PATCH v12 0/2] Add VT-d Posted-Interrupts support

[Feng Wu <feng.wu@xxxxxxxxx>]

VT-d Posted-Interrupts is an enhancement to CPU side Posted-Interrupt.
With VT-d Posted-Interrupts enabled, external interrupts from
direct-assigned devices can be delivered to guests without VMM
intervention when guest is running in non-root mode.

You can find the VT-d Posted-Interrtups Spec. in the following URL:
