: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? :
The 4GB limitation only applies to memory addresses. Block devices and files have no such limitation ... 'off_t' has been 64 bits for many years. You can create filesystems and files up to 2TB in size in -stable and it will be virtually unlimited in -current. -Matt Matthew Dillon <[EMAIL PROTECTED]> To Unsubscribe: send mail to [EMAIL PROTECTED] with "unsubscribe freebsd-hackers" in the body of the message
