Expand description

Invalidate hypervisor translation cache for guest physical address

This instruction invalidates any address-translation cache entries that an HFENCE.GVMA instruction with the same values of gaddr and vmid would invalidate.

This fence specifies a single guest physical address; the physical address should be shifted right by 2 bits.
