[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

[PATCH V6 OLK-6.6 0/2] Introduce BPF_READAHEAD option for optimizing read performance
by ZhaoLong Wang 24 Apr '24

24 Apr '24

This patch series introduces a new configuration option called BPF_READAHEAD, which is designed to optimize the read performance in Spark SQL scenarios using eBPF to implement a programmable kernel. The first patch adds the BPF_READAHEAD option to the kernel configuration, along with the necessary changes to the filesystem and memory management code to support this feature. The option is disabled by default and depends on CONFIG_TRACEPOINTS. The second patch enables the BPF_READAHEAD option in the openeuler_defconfig files for arm64, powerpc, riscv, and x86 architectures. This ensures that the feature is available on the supported architectures when needed. The BPF_READAHEAD option allows for fine-tuning the kernel's readahead behavior based on the application's read patterns, leading to improved read performance in specific scenarios like Spark SQL.

[PATCH OLK-5.10 0/4] Add hugetlb MADV_DONTNEED support

MADV_DONTNEED is currently disabled for hugetlb mappings. This certainly makes sense in shared file mappings as the pagecache maintains a reference to the page and it will never be freed. However, it could be useful to unmap and free pages in private mappings.
