: :This is also the _default_ for how solaris manages sysv segments, :although it would be nice if we could get the OBJT_PHYS stuff to :use 4meg pages (unless someone already did that?)... : :Anyhow, I'm glad we corrected your misconception and we now have :a more accurate understanding of how this system works. : :-Alfred
Even more importantly it would be nice if we could share compatible pmap pages, then we would have no need for 4MB pages... 50 mappings of the same shared memory segment would wind up using the same pmap pages as if only one mapping had been made. Such a feature would work for SysV shared memory and for mmap()s. I've looked at doing this off and on for two years but do not have a sufficient chunk of time available yet. -Matt To Unsubscribe: send mail to [EMAIL PROTECTED] with "unsubscribe freebsd-hackers" in the body of the message
