If RAM + swap can be more than 4GB, how does FreeBSD address swap on a 32-bit machine? Does the kernel internally use a wider address space with some kind of translation to 32-bit space for programs and hardware that can't handle 64-bit addresses or does it not map swap into the address space at all, instead using it as a kind of "offline" storage for pages not in use? Does the Alpha port handle swap the same way? To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
