- layer8 2y agoThe proposal doesn’t remove 32-bit user land or (I think) virtualization.
- wtallis 2y agoX86S allows 32-bit ring3 (userland) but even VMs are stuck in long mode and only support 32-bit code for userland. Booting a VM for a 64-bit OS that has a legacy bootloader with 16-bit or 32-bit code would require software emulation of that code.
