However, those pages are used for the kernel and device buffers (like video mem.) I do know that certain applications can gain from pre-allocated memory regions that are mapped by 4MB pages. If you have any info on the actual performance gains, it would be useful. I would certainly be willing to implement it, if it ends up giving any reasonable improvement. -- John | Never try to teach a pig to sing, dyson@freebsd.org | it just makes you look stupid, jdyson@nc.com | and it irritates the pig.
