nit: active-less SGIs are not strictly a feature of GICv4.1 (you could
imagine a GIC emulation offering the same thing). Furthermore, GICv4.1
isn't as such visible to the guest itself (it only sees a GICv3).

Yes, but to measure the performance difference of hw/sw SGI injection,
do you think it is acceptable to make it visible to guest and let it
switch SGI injection mode?

Thanks,
Jingyi
