    > I wish ARM64, RISC-V, and other modern ISAs had taken DEC Alpha AXP's idea of restricting all of the privileged instructions to the firmware

    This is already possible on RISC-V to some extend, by trapping privileged instructions into upper privileged modes. Everything in the ISA is made so it may be achieved cleanly. It also does not allow to detect current privileged mode, so the kernel running in U-mode and trapped on each privileged instruction would never know it's actually not in S-mode.

    There is even a software-based hypervisor extension emulator based on that, that brings KVM to non-hypervisor-capable HW: https://github.com/dramforever/opensbi-h
