I read in vm_map_lookup() the following comment: /* * If this page is not pageable, we have to get it for all possible * accesses. */ Does this mean that even if the map entry is specified as wired, the pages in its range still have to be faulted in for the very first time? Another question: Can any process wire a page at its own will? There must be some regulations, otherwise anyone can hog the memory. Any help is appreciated. -------------------------------------------------- | Zhihui Zhang, http://cs.binghamton.edu/~zzhang | | Dept. of Computer Science, SUNY at Binghamton | -------------------------------------------------- To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
