Part of the bhyve porting work involved implementing a shim to FreeBSD's VM system which created and managed EPT-compatible structures for the HVM guest. The initial layer for this in illumos was rudimentary, but included some of the indexing features inspired in the HAT/htable logic in the OS. Since there are several different areas in bhyve (EPT for Intel, SVM for AMD, the IOMMUs, etc) which could benefit from the same generic systems used by such paging tables, it would be nice to have that abstracted into a common API.
Things it could cover:
