[PATCH OLK-6.6 0/4] A Solution to Re-enable hugetlb vmemmap optimize on ARM64
by Nanyong Sun 25 Apr '24

25 Apr '24

HVO was previously disabled on arm64 [1] due to the lack of necessary BBM(break-before-make) logic when changing page tables. This set of patches fix this by adding necessary BBM sequence when changing page table, and supporting vmemmap page fault handling to fixup kernel address translation fault if vmemmap is concurrently accessed. I have tested this patch set with concurrently accessing the vmemmap address when do BBM and can recover by vmemmap fault handler. Also tested under the config of 2/3/4 pgtable levels with 4K/64K page size and all works well. [1] commit 060a2c92d1b6 ("arm64: mm: hugetlb: Disable HUGETLB_PAGE_OPTIMIZE_VMEMMAP") Nanyong Sun (4): mm: HVO: introduce helper function to update and flush pgtable arm64: mm: HVO: support BBM of vmemmap pgtable safely arm64: mm: Re-enable OPTIMIZE_HUGETLB_VMEMMAP arm64: update openeuler_defconfig for HVO enable arch/arm64/Kconfig | 1 + arch/arm64/configs/openeuler_defconfig | 3 + arch/arm64/include/asm/esr.h | 4 ++ arch/arm64/include/asm/pgtable.h | 7 ++ arch/arm64/include/asm/tlbflush.h | 16 +++++ arch/arm64/mm/fault.c | 94 ++++++++++++++++++++++++-- arch/arm64/mm/mmu.c | 28 ++++++++ mm/hugetlb_vmemmap.c | 51 +++++++++++--- 8 files changed, 189 insertions(+), 15 deletions(-) -- 2.25.1

[PATCH OLK-6.6 0/3] A Solution to Re-enable hugetlb vmemmap optimize
by Nanyong Sun 24 Apr '24

24 Apr '24

HVO was previously disabled on arm64 [1] due to the lack of necessary BBM(break-before-make) logic when changing page tables. This set of patches fix this by adding necessary BBM sequence when changing page table, and supporting vmemmap page fault handling to fixup kernel address translation fault if vmemmap is concurrently accessed. I have tested this patch set with concurrently accessing the vmemmap address when do BBM and can recover by vmemmap fault handler. Also tested under the config of 2/3/4 pgtable levels with 4K/64K page size and all works well. [1] commit 060a2c92d1b6 ("arm64: mm: hugetlb: Disable HUGETLB_PAGE_OPTIMIZE_VMEMMAP") Nanyong Sun (3): mm: HVO: introduce helper function to update and flush pgtable arm64: mm: HVO: support BBM of vmemmap pgtable safely arm64: mm: Re-enable OPTIMIZE_HUGETLB_VMEMMAP arch/arm64/Kconfig | 1 + arch/arm64/include/asm/esr.h | 4 ++ arch/arm64/include/asm/pgtable.h | 7 +++ arch/arm64/include/asm/tlbflush.h | 16 ++++++ arch/arm64/mm/fault.c | 94 +++++++++++++++++++++++++++++-- arch/arm64/mm/mmu.c | 28 +++++++++ mm/hugetlb_vmemmap.c | 51 +++++++++++++---- 7 files changed, 186 insertions(+), 15 deletions(-) -- 2.25.1
