Have you got some pointers which explain FreeBSD's > KVA ? I have written documentation for FreeBSD 4.3/4.4. Unfortunately, everyone keeps substituting activity for action, and hacking away at the code, so it doesn't sit still long enough to match any useful documentation; otherwise, I would have published what I wrote in Pentad Embedded Systems Journal already (example: the KVA_PAGES stuff came in after FreeBSD 4.3/4.4, and blew out two paragraphs on what to modify where, and how to calculate the values to use). The best documentation is probably Matt Dillon's article in Daemon News, the FreeBSD Developer's handbook, or the German guy's article in English (sorry for not remembering your name), depending on what part of things you are interested in. If you could get people to leave the damn code alone for a while, I'd be willing to update my article to FreeBSD RELENG_4 (-STABLE), and publish it. One of the major problems with undocumented code is that weenies are unwilling to sit down and understand it, so they rewrite it to understand it, instead, and then you are still without documentation. Documentation that's "almost right" is unbelievably worse than no documentation at all. -- Terry To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
