Closing Keynote: The Joy and Excitement of Forbidden Computer
summary
A hardware/software project reproduces QEMU/Kimu’s TCG by emitting pre-generated gadget chains (every ARM64 snippet for Kimu IR) and stitching them with a custom tiny code threaded interpreter, avoiding iOS JIT restrictions. Benchmarks show native boot ~12s, original JIT ~18s, interpreter ~78–120s, and the threaded approach ~36s. The implementation lands in UTM as the usable UTM slow Edition, restores VM use on modern iPhones, and demonstrably halves boot time versus the plain interpreter.
