I’ve seen people talking about it and experienced it myself with a server, but why does Linux run so well on ARM (especially compared to Windows)?

    Small correction: the flag setting modes aren’t undocumented. They’re standardized extensions. ARMv8.4 added FEAT_FlagM, and ARMv8.5 added FEAT_FlagM2.

    IIRC, the only nonstandard ARM extension used by Rosetta 2 in Apple’s processors is TSO, and that’s also implemented by other manufacturers. It’s also not a hard requirement to run amd64 under ARM. You can emulate it very slowly or restrict the application to a single core.

    Apologies for the tangent, but I needed to make sure nobody could defend Microsoft’s prior failings by saying “but Apple has secret hardware sauce”.
