All of this is nice and fine, but the take home notion here is that there's more than a "maximum" or a "preferred" size. There's also a "required request size". And this isn't a constant value you can stash in a dev_t- or you'll have to have drivers change it as required. It seems to me that the physio should just be beefed up to take an argument to a 'parameterization' function, and that flags could be used that say "we don't even need this mapped any where- just make sure that the pages referred to are resident". All of the other stuff is really more of a tight interaction with VM for optimizing. -matt To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-arch" in the body of the message
