Expand description
Invalidate hypervisor translation cache for guest physical address and virtual machine
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, shifted right by 2 bits, and a single virtual machine by virtual machine identifier (VMID).
