Bug description:
Posted Interrupts on Broadwell is really VT-d posted interrupts.
Posted Interrupts for the processor are part of the APIC-V and was
introduced in IVT. The idea is that the interrupt can be placed in a
data structure for the guest and the guest can, under the right
conditions, receive the interrupt without VM exiting. Chapter 29 of
vol. c of the SDM has the currently public part of posted interrupts.
