In pmap.c module, we set PTDPTDI entry of the page directory page to point to itself. So PTDpde and PTmap works well. However, I do not find a similar setting of APTDTDI (=1023) in pmap.c. My question is how APTDpde and the alternate address space it's supposed to relate to (APTmap) are used. (has something to do with pmap copy?) 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
