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.
