We do envision that "direct guest TLB management" is an opt-in option that a guest can enable. If LRAT is on, with TLB management directly handled by guests, the only mechanism we have to do TLB1 invalidates is tlbwe. That is our only option as far as I know. So, hugetlb and indirect entries will each need to be addressed separately. The kernel code that handles these either needs to be A) modified to unconditionally do all invalidates by tlbwe or B) conditionally use tlbwe depending on whether this is a guest that has enabled direct TLB management.
