Question regarding HIE in KVM

Hi all,

I was looking through the KVM source code and it seems like HIE bits are never set to enable VS-level interrupts. However, there is the expected  HVIP write to trigger the interrupt. Am I correct in that KVM doesn’t use HIE? What is the expected behavior in this case?

Thanks
Jiahan
