  • 2a11c8ea2   kconfig: Introduce IS_ENABLED(), IS_BUILTIN() and IS_MODULE() ... Browse Code »

    Replace the config_is_*() macros with a variant that allows for grepping
    for usage of CONFIG_* options in the code. Usage:

    if (IS_ENABLED(CONFIG_NUMA))

    or

    #if IS_ENABLED(CONFIG_NUMA)

    The IS_ENABLED() macro evaluates to 1 if the argument is set (to either 'y'
    or 'm'), IS_BUILTIN() tests if the option is 'y' and IS_MODULE() test if
    the option is 'm'. Only boolean and tristate options are supported.

  • eb4cf5a64   kconfig: fix missing "0x" prefix from S_HEX symbol in autoconf.h ... Browse Code »

    The specialized printer for headers (espectially autoconf.h) is missing
    fixup code for S_HEX symbol's "0x" prefix. As long as kconfig does not
    warn for such missing prefix, this code is needed. Fix this.

    In the same time, fix some nits in `header_print_symbol()'.

    After the test

    if (!submenu || ...)
    continue;

    the variable `submenu' can _not_ be NULL, so do not test for this
    situation.

  • f98ee7695   kconfig/nconf: prevent segfault on empty menu ... Browse Code »

    nconf does not check the validity of the current menu when help is
    requested (with either , '?' or 'h'). This leads to a NULL pointer
    dereference when an empty menu is encountered.

    The following reduced testcase exposes the problem:

    config DEP
    bool

    menu "FOO"

    config BAR
    bool "BAR"
    depends on DEP

    endmenu

    Issue will happen when entering menu "FOO" and requesting help.

    nconf is the only front-end which do not filter the validity of the
    current menu. Such filter can not really happen beforehand as other key
    which does not deals with the current menu might be entered by the user,
    so just bails out earlier if we encounter an invalid menu.

    nconf is the only front-end which does not use this helper, but prefer
    to copy/paste the code. The test wrt. menu validity added in this
    version of the code is bogus anyway as an invalid menu will get
    dereferenced a few line below by calling menu_get_prompt().

    For now, convert nconf to use menu_get_ext_help(), as do every other
    front-end. We will deals with menu validity checks properly in a
    separate commit.

    I am seeing Wunused-but-set warning while make nconfig. Looks like
    active_menu is not used. Removing it fixes the warning.

  • e54e692ba   kconfig: introduce specialized printer ... Browse Code »

    Make conf_write_symbol() grammar agnostic to be able to use it from different
    code path. These path pass a printer callback which will print a symbol's name
    and its value in different format.

    conf_write_symbol()'s job become mostly only to prepare a string for the
    printer. This avoid to have to pass specialized flag to generic
    functions

    Considering the following configuration:

    config F
    bool "F"

    choice AB
    bool "AB"
    config A
    bool "A"
    config B
    bool "B"
    endchoice

    if A
    config D
    bool
    default y if F
    select E
    config E
    bool "E"
    endif

    if B
    config D
    bool
    default y if F
    select E
    config E
    bool "E"
    endif

    The following configuration:

    CONFIG_F=y
    CONFIG_A=y
    # CONFIG_B is not set
    CONFIG_D=y
    CONFIG_E=y

    emits a spurious warning:

    (D) selects E which has unmet direct dependencies (B)

    If a symbol appears in two different branch of the tree, it should inherit the
    dependency of both parent, not just the last one.

  • de125187d   kconfig: autogenerated config_is_xxx macro ... Browse Code »

    this will allow to use to use

    if(config_is_xxx())
    if(config_is_xxx_module())

    in the code instead of

    #ifdef CONFIG_xxx
    #ifdef CONFIG_xxx_MODULE

    and now let the compiler remove the non usefull code and not the
    pre-processor

    as done in the mach-types for arm as exmaple
