The accelerator- and target-independent parts of the basic emulation are already in hw/core (not much really, but consider that CPUs are device and depend on hw/core/qdev.c). The memory API is simply the interface between the accelerators and hw/ (boards & device models). In fact, apart from large parts of exec.c which are really part of the memory API implementation (but I'm not moving it in this patch for simplicity), the other users of the memory API are really the accelerators. KVM and Xen only use listeners, TCG needs more low-level access in cputlb.c and translate-all.c but that's pretty much it. Paolo
