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 arch/arm/include/asm/kvm_host.h | 5 - arch/arm/include/asm/kvm_mmu.h | 17 +++- arch/arm/kvm/mmu.c | 200 ++++++++++++++++++++++++++++++++------ arch/arm64/include/asm/kvm_mmu.h | 12 ++- arch/x86/include/asm/kvm_host.h | 7 ++ include/linux/kvm_host.h | 7 -- 6 files changed, 201 insertions(+), 47 deletions(-) -- 1.7.10.4 -- To unsubscribe from this list: send the line "unsubscribe kvm" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html
