Well, probably not on device ;-).

The underlying Reverie instrumentation layer works on ARM, but Hermit isn't ported yet, and we haven't touched RISC-V yet at all. (Contributions welcome!)

One thing we haven't tried yet is just putting a whole emulator (qemu etc) underneath Hermit. That would address any sources of irreproducibility that the emulator lets through from the host (threads, RNG, etc).
