Hello, I'm trying to, given a virtual address, quickly check if it exists (if it is mapped) to know if I can access it in a safe way, without generating an exception. I'm currently using the AT instruction to check if a virtual address exists. Is there an alternative or better way to do this?
Thank you in advance
w/o MMU no virtual address. I never tried the outcome, but I guess it wil indicate a fault (as there is no mapping for any address).
