I’m not sure I understand how microcode is a problem here. Microcode isn’t an OS. I can compile for arm 8.3 and execute those instructions on apple silicon just fine. The kernel is the only thing that gets in the way, not the microcode…
I guess they mean the coprocessor stuff, ime and whatever the AMD one is called.
I mean this does forget the point that absolutely nothing is stopping anyone making a riscv processor which also has such features; we just have to take the manufacturer’s word that they don’t? Riscv isn’t the solution to any of these problems, but hopefully it’ll enable a few more ethical manufacturers to pop up who do make this stuff their core mission.
