From: Marcelo Tosatti Date: Sat, 23 Feb 2008 14:44:30 +0000 (-0300) Subject: KVM: MMU: large page support X-Git-Tag: v2.6.26-rc1~1028^2~99 X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=05da45583de9b383dc81dd695fe248431d6c9f2b;p=pandora-kernel.git KVM: MMU: large page support Create large pages mappings if the guest PTE's are marked as such and the underlying memory is hugetlbfs backed. If the largepage contains write-protected pages, a large pte is not used. Gives a consistent 2% improvement for data copies on ram mounted filesystem, without NPT/EPT. Anthony measures a 4% improvement on 4-way kernbench, with NPT. Signed-off-by: Marcelo Tosatti Signed-off-by: Avi Kivity --- Reading git-diff-tree failed
