I'm curious to see the Google projects that have patches from Apple, since all of those run on Android which is for all intents and purposes ARM. I'm guessing new ARMv8 ISA features, PAC/BTI/MTE?
Yes, ARM Mac will make fully use of ARM security and hardware mitigations against typical C exploits, there are a couple of WWDC talks about it.

Apple has Hypervisor.framework which has been updated for ARM Mac[1]. Xhyve and HyperKit (used by Docker for Mac) uses Hypervisor.framework exclusively. The last time I tried Hypervisor.framework on x86-64, the CPU performance was quite fine (matches that of VMware/VirtualBox), but I/O was pretty abysmal. Emulating x86-64 on ARM is probably going to be a role of something similar to QEMU. [1]: https://developer.apple…
Cool! Does docker no longer use virtual box on macOS?

Disclosure: I work at AWS building cloud infrastructure C6g, M6g, and R6g (powered by AWS Graviton2) each support 8 sizes, along with bare metal. A1 instances (powered by AWS Graviton) have 5 sizes, along with bare metal. That's a total of 33 distinct instance sizes.
Thanks, I didn't know about c6g, m6g, r6g. I've updated the post to remove this mention - I only counted a1 instances. That still leaves storage optimized and GPU optimized instances missing. I'm guessing storage should be easy enough to add, but what about GPU? From my novice experience with GPUs, they need finicky drivers that must be ported by the GPU manufacturers, so I figure it might take a while to get competi…
