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
