The main differences with the currently implemented method are: - Requires a local APIC EOI, since it doesn't bypass the local APIC as the previous method used to do. - Can be set to use different IDT vectors on each vCPU. Note that FreeBSD doesn't make use of this feature since the event channel IDT vector is reserved system wide. Note that the old method of setting the event channel upcall is not removed, and will be used as a fallback if this newly introduced method is not available.
