Subject: Is there anyway to use 4M pages on x86 linux in user level?
Date: Thu, 17 Jan 2002 12:18:45 -0500 [thread overview]
Message-ID: <F198nwpGR881Np7vXee0002516d@hotmail.com> (raw)
Hi,
I am working on a project that keep accessing lots of memory randomly(say
500MB-1.5GB) and we do have such amount of memory installed so there's
almost no page faults while running the entire program. Since x86
architecutre has a 4M page feature, is it possible to make use of these big
pages instead of 4K pages in my program (a user-level application) so I can
expect much fewer TLB misses due to the reduced number of TLB entries?
Thanks very much!
