  • 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

  • 172733959   clocksource/drivers: Rename CLOCKSOURCE_OF_DECLARE to TIMER_OF_DECLARE ... Browse Code »

    The CLOCKSOURCE_OF_DECLARE macro is used widely for the timers to declare the
    clocksource at early stage. However, this macro is also used to initialize
    the clockevent if any, or the clockevent only.

    It was originally suggested to declare another macro to initialize a
    clockevent, so in order to separate the two entities even they belong to the
    same IP. This was not accepted because of the impact on the DT where splitting
    a clocksource/clockevent definition does not make sense as it is a Linux
    concept not a hardware description.

    On the other side, the clocksource has not interrupt declared while the
    clockevent has, so it is easy from the driver to know if the description is
    for a clockevent or a clocksource, IOW it could be implemented at the driver
    level.

    So instead of dealing with a named clocksource macro, let's use a more generic
    one: TIMER_OF_DECLARE.

    The patch has not functional changes.

  • 177cf6e52   clocksources: Switch back to the clksrc table ... Browse Code »

    All the clocksource drivers's init function are now converted to return
    an error code. CLOCKSOURCE_OF_DECLARE is no longer used as well as the
    clksrc-of table.

    Let's convert back the names:
    - CLOCKSOURCE_OF_DECLARE_RET => CLOCKSOURCE_OF_DECLARE
    - clksrc-of-ret => clksrc-of

  • eacf20916   clocksource/drivers/h8300_timer16: Convert init function to return error ... Browse Code »

    The init functions do not return any error. They behave as the following:

    - panic, thus leading to a kernel crash while another timer may work and
    make the system boot up correctly

    or

    - print an error and let the caller unaware if the state of the system

    Change that by converting the init functions to return an error conforming
    to the CLOCKSOURCE_OF_RET prototype.

    Proper error handling (rollback, errno value) will be changed later case
    by case, thus this change just return back an error or success in the init
    function.
