Google developing own CPUs for Chromebook laptops

There is some minor breakage, like Apple CPUs enforcing the VHE feature of ARMv8.1-A to be on, and not supporting it being off. But that was like… the sole issue on that front.

What you are allowed to do is make extensions with the highest tier of arch licenses, you however cannot break the ISA.

VHE isn't even observable for userspace code, and Apple is very quickly going to drop support for people being in the kernel, so I would argue this probably isn't even that important.

For macOS at Reduced Security, kernel extensions will no longer be supported.

fuOS/CustomKC will stay in the long term, and that's what matters for other OSes.

Thanks! Very interesting on VHE.
