  • e0a491c12   lib/raid6: Add AVX512 optimized gen_syndrome functions ... Browse Code »

    Optimize RAID6 gen_syndrom functions to take advantage of
    the 512-bit ZMM integer instructions introduced in AVX512.

    AVX512 optimized gen_syndrom functions, which is simply based
    on avx2.c written by Yuanhan Liu and sse2.c written by hpa.

    The patch was tested and benchmarked before submission on
    a hardware that has AVX512 flags to support such instructions

  • df6b35f40   x86/fpu: Rename i387.h to fpu/api.h ... Browse Code »

    We already have fpu/types.h, move i387.h to fpu/api.h.

    The file name has become a misnomer anyway: it offers generic FPU APIs,
    but is not limited to i387 functionality.

  • 7056741fd   lib/raid6: Add AVX2 optimized recovery functions ... Browse Code »

    Optimize RAID6 recovery functions to take advantage of
    the 256-bit YMM integer instructions introduced in AVX2.

    The patch was tested and benchmarked before submission.
    However hardware is not yet released so benchmark numbers
    cannot be reported.
