QEMU with this feature should have the vIOMMU maintain a cache of the guest io page table addresses and assign a unique IOAS to each unique guest page table.
I didn't get why we impose such requirement to userspace.
I read this as implementation guidance for qemu. qemu can do what it wants of course
