Since VT-d PI cannot handle broadcast/multicast interrupt, Here we only handle Fixed and Lowest priority interrupts. The current method of handling guest lowest priority interrtups is to use a counter 'apic_arb_prio' for each vCPU, we choose the vCPU with smallest 'apic_arb_prio' and then increase it by 1. However, for VT-d PI, we cannot re-use this, since we no longer have control to 'apic_arb_prio' with posted interrupt direct delivery by Hardware. Here, we introduce a similar way with 'apic_arb_prio' to handle guest lowest priority interrtups when VT-d PI is used. Here is the ideas: - Each vCPU has a counter 'round_robin_counter'. - When guests sets an interrupts to lowest priority, we choose the vCPU with smallest 'round_robin_counter' as the destination, then increase it.
