Luigi reported that the retrigger mechanism for posted MSI interrupts is broken. That happens because retrigger sends an IPI to the actual allocated vector, which is handled correctly, but lacks an EOI. That leaves a stale APIC ISR bit around.
The following series addresses this and does some related cleanups in that area on top.
Thanks,
