  • 821489934   x86/cpufeature: Add AVX512_4VNNIW and AVX512_4FMAPS features ... Browse Code »

    AVX512_4VNNIW - Vector instructions for deep learning enhanced word
    variable precision.
    AVX512_4FMAPS - Vector instructions for deep learning floating-point
    single precision.

    These new instructions are to be used in future Intel Xeon & Xeon Phi
    processors. The bits 2&3 of CPUID[level:0x07, EDX] inform that new
    instructions are supported by a processor.

    The spec can be found in the Intel Software Developer Manual (SDM) or in
    the Instruction Set Extensions Programming Reference (ISE).

    Define new feature flags to enumerate the new instructions in /proc/cpuinfo
    accordingly to CPUID bits and add the required xsave extensions which are
    required for proper operation.

  • f82b77462   tools include: Add mman macros needed by perf for all arch ... Browse Code »

    Some macros required by tools/perf/trace/beauty/mmap.c is not support
    for all architectures. For example, MAP_32BIT is defined on x86 only,
    alpha doesn't define MADV_HWPOISON and MADV_SOFT_OFFLINE.

    This patch regenerates mman.h for each arch, defines these missing
    macros for perf. For missing MADV_*, fall back to asm-generic/mman-common
    because they are in a 'case ...' statement. For flags, define it to 0.

    Following is the script to generate this patch:

    macros=`cat $0 | awk 'V==1 {print}; /^# start macro list/ {V=1}'`
    rm `find ./tools/arch/ -name mman.h`
    for arch in `ls tools/arch`

    done

    if [ -f $src ]
    then

  • f3539c12d   tools include: Add uapi mman.h for each architecture ... Browse Code »

    Some mmap related macros have different values for different
    architectures. This patch introduces uapi mman.h for each
    architectures.

    Three headers are cloned from kernel include to tools/include:

    There were changes related to the deprecation of the "pcommit"
    instruction:

    fd1d961dd681 ("x86/insn: remove pcommit")
    dfa169bbee00 ("Revert "KVM: x86: add pcommit support"")

    No need to update anything in the tools, as "pcommit" wasn't being
    listed on the VMX_EXIT_REASONS in the tools/perf/arch/x86/util/kvm-stat.c
    file.

    Just grab fresh copies of these files to silence the file cache
