How is that possible without page fault exceptions or equivalent?
- monocasa 4y agoThe MPU gives you an equivalent of page fault exceptions. You can't remap virtual addresses to physical, but you can change their permissions, trap into the kernel when those permissions are violated, and restart execution of processes after the trap (to deliver signals or what have you).
