  • b24413180   License cleanup: add SPDX GPL-2.0 license identifier to files with no license ... Browse Code »

    Many source files in the tree are missing licensing information, which
    makes it harder for compliance tools to determine the correct license.

    By default all files without license information are under the default
    license of the kernel, which is GPL version 2.

    Update the files which contain no license information with the 'GPL-2.0'
    SPDX license identifier. The SPDX identifier is a legally binding
    shorthand, which can be used instead of the full boiler plate text.

    This patch is based on work done by Thomas Gleixner and Kate Stewart and
    Philippe Ombredanne.

    How this work was done:

    Patches were generated and checked against linux-4.14-rc6 for a subset of
    the use cases:
    - file had no licensing information it it.
    - file was a */uapi/* one with no licensing information in it,
    - file was a */uapi/* one with existing licensing information,

    Further patches will be generated in subsequent months to fix up cases
    where non-standard license headers were used, and references to license
    had to be inferred by heuristics based on keywords.

    The analysis to determine which SPDX License Identifier to be applied to
    a file was done in a spreadsheet of side by side results from of the
    output of two independent scanners (ScanCode & Windriver) producing SPDX
    tag:value files created by Philippe Ombredanne. Philippe prepared the
    base worksheet, and did an initial spot review of a few 1000 files.

    The 4.13 kernel was the starting point of the analysis with 60,537 files
    assessed. Kate Stewart did a file by file comparison of the scanner
    results in the spreadsheet to determine which SPDX license identifier(s)
    to be applied to the file. She confirmed any determination that was not
    immediately clear with lawyers working with the Linux Foundation.

    Criteria used to select files for SPDX license identifier tagging was:
    - Files considered eligible had to be source code files.
    - Make and config files were included as candidates if they contained >5
    lines of source
    - File already had some variant of a license header in it (even if

  • 25b8592e9   perf powerpc: Fix build-test failure ... Browse Code »

    'make -C tools/perf build-test' is failing with below log for poewrpc.

    In file included from /tmp/tmp.3eEwmGlYaF/perf-4.8.0-rc4/tools/perf/perf.h:15:0,
    from util/cpumap.h:8,
    from util/env.c:1:
    /tmp/tmp.3eEwmGlYaF/perf-4.8.0-rc4/tools/perf/perf-sys.h:23:56:
    fatal error: ../../arch/powerpc/include/uapi/asm/unistd.h: No such file or directory
    compilation terminated.

    I bisected it and found it's failing from commit ad430729ae00 ("Remove:
    kernel unistd*h files from perf's MANIFEST, not used").

    Header file '../../arch/powerpc/include/uapi/asm/unistd.h' is included
    only for powerpc in tools/perf/perf-sys.h.

    By looking closly at commit history, I found little weird thing:

    Commit f2d9cae9ea9e ("perf powerpc: Use uapi/unistd.h to fix build
    error") replaced 'asm/unistd.h' with 'uapi/asm/unistd.h'

    Commit d2709c7ce4c5 ("perf: Make perf build for x86 with UAPI
    disintegration applied") removes all arch specific 'uapi/asm/unistd.h'
    for all archs and adds generic .

    Commit f0b9abfb0446 ("Merge branch 'linus' into perf/core") again
    includes 'uapi/asm/unistd.h' for powerpc. Don't know how exactly this
    happened as this change is not part of commit also.

    And remove the empty tools/arch/x86/include/asm/unistd_{32,64}.h files
    introduced by eae7a755ee81 ("perf tools, x86: Build perf on older

    This way we get closer to mirroring the kernel for cases where __NR_
    can't be found for some include path/_GNU_SOURCE/whatever scenario.

  • 493c30313   perf tools: Make CPUINFO_PROC an array to support different kernel versions ... Browse Code »

    After kernel 3.7 (commit b4b8f770eb10a1bccaf8aa0ec1956e2dd7ed1e0a),
    /proc/cpuinfo replaces 'Processor' to 'model name'.

    This patch makes CPUINFO_PROC to an array and provides two choices for
    ARM, makes it compatible for different kernel version.

    v1 -> v2: minor changes as suggested by Namhyung Kim:

    - Doesn't pass @h and @evlist to __write_cpudesc;
    - Coding style fix.

    v2 -> v3:
    - Rebase:

    Into new perf-sys.h header.

    The main reason is to separate system specific perf data
    from perf tool stuff, so it could be used in small test
    programs, as requested Peter:

    http://lkml.kernel.org/r/20140502115201.GI30445@twins.programming.kicks-ass.net

    This separation makes the perf.h header more clear.
