Proposes a concrete decomposition of ARM ASL into an unprivileged core and a small privileged handler so one common unprivileged semantics can be reused across bare-metal and virtualized runs. Builds a prototype interface around an address-translation handle (translate → read/write) and integrates with the microkernel Nova plus a C++ VMM; several instructions are refactored and many VMM C++ routines are mechanically verified, while the full ASL rewrite and end-to-end mechanized simulation remain work in progress.
