Subject: [PATCH 0/3] KVM/ARM Huge pages support
Date: Thu, 8 Aug 2013 21:07:16 -0700 [thread overview]
Message-ID: <1376021239-10532-1-git-send-email-christoffer.dall@linaro.org> (raw)
This small series adds support for Transparent Huge Pages and hugetlbfs
pages for KVM on the arm and arm64 architectures.
Measurements have shown that using huge pages in for stage-2 mappings
provides up to more than 15% performance increase for some workloads.
The patch series applies to kvm/next, but depends on the patch sent
earlier:
"ARM: KVM: Fix unaligned unmap_range leak"
Christoffer Dall (3):
KVM: Move gfn_to_index to x86 specific code
KVM: ARM: Get rid of KVM_HPAGE_XXX defines
KVM: ARM: Transparent huge pages and hugetlbfs support
