Is it possible for other x86-64 emulators on M1 to leverage the same optimizations used by Rosetta 2?

I am curious about the vastly different performance characteristics of running x86-64 binaries on the Apple M1 platform using Rosetta 2 vs. emulation, for example what Docker Desktop currently does using QEMU. I understand why emulation is so slow,…

Why can't QEMU get even close to Rosetta 2's performance when translating x86 to M1?

Apparently, QEMU is the only piece of open source code that can emulate an x86 operating system on the new Apple silicon (M1, M2, etc.). Apple built Rosetta 2, which, in theory, does the exact same thing that QEMU would be doing in these scenarios.…
