  • 98f540d31   kconfig: resort the documentation of the environment variables ... Browse Code »

    All the KCONFIG_ environment variables were previously located in a
    section "Environment variables in 'menuconfig'", but neither are they
    restricted to 'menuconfig' nor are they all used by 'menuconfig'.

    Introduce the following three sections for these variables:
    * Environment variables for '*config'
    * Environment variables for '{allyes/allmod/allno/rand}config'
    * Environment variables for 'silentoldconfig'

    Furthermore this puts MENUCONFIG_MODE next to MENUCONFIG_COLOR into a
    common section "User interface options for 'menuconfig'".

  • 720097d89   kbuild: introduce subdir-ccflags-y ... Browse Code »

    Following patch introduce support for setting options
    to gcc that has effect for current directory and all
    subdirectories.

    The typical use case are an architecture or a subsystem that
    decide to cover all files with -Werror.
    Today alpha, mips and sparc uses -Werror in almost all their
    Makefile- with subdir-ccflag-y it is now simpler to do so
    as only the top-level directories needs to be covered.

    Likewise if we decide to cover a full subsystem such
    as net/ with -Werror this is done by adding a single
    line to net/Makefile.

    Mostly contains user interface, environment variables, and search topics,
    along with mini.config/custom.config usage.

  • 5410ecc0d   kbuild: introduce $(kecho) convenience echo ... Browse Code »

    There is a bunch of places in the build system where we do 'echo' to show
    some nice status lines. This means we still get output when running in
    silent mode. So declare a new KECHO variable that only does 'echo' when we
    are in a suitable verbose build mode.

    This patch adds a new (Kbuild) Makefile variable KBUILD_EXTRA_SYMBOLS.
    The space separated list of file names assigned to KBUILD_EXTRA_SYMBOLS
    is used when calling scripts/mod/modpost during stage 2 of the Kbuild
    process for non-kernel-tree modules.

  • 910b40468   kbuild: introduce cc-cross-prefix ... Browse Code »

    cc-cross-prefix is useful for the architecture that like
    to provide a default CROSS_COMPILE value,
    but may have several to select between.

    Sample usage:

    ifneq ($(SUBARCH),$(ARCH))
    ifeq ($(CROSS_COMPILE),)
    CROSS_COMPILE := $(call cc-cross-prefix, m68k-linux-gnu- m68k-linux-)
    endif
    endif

    Actual usage by the different archs will taken care of later.

  • f77bf0142   kbuild: introduce ccflags-y, asflags-y and ldflags-y ... Browse Code »

    Introduce ccflags-y, asflags-y and ldflags-y so we soon can
    deprecate use of EXTRA_CFLAGS, EXTRA_AFLAGS and EXTRA_LDFLAGS.
    This patch does not touch any in-tree users - thats next round.
    Lets get this committed first and then fix the users of the
    soon to be deprecated variants next.

    The rationale behind this change is to introduce support for
    makefile fragments like:

    ccflags-$(CONFIG_WHATEVER_DEBUG) := -DDEBUG

    As a replacement for the uglier:
    ifeq ($(CONFIG_WHATEVER_DEBUG),y)
    EXTRA_CFLAGS := -DDEBUG
    endif

    This patch replace use of CPPFLAGS with KBUILD_CPPFLAGS all over the

    make CPPFLAGS=...
    to specify additional CPP commandline options.

    Patch was tested on following architectures:

    The variable CFLAGS is a wellknown variable and the usage by
    kbuild may result in unexpected behaviour.
    On top of that several people over time has asked for a way to
    pass in additional flags to gcc.

    This patch replace use of CFLAGS with KBUILD_CFLAGS all over the
    tree and enabling one to use:
    make CFLAGS=...
    to specify additional gcc commandline options.

    One usecase is when trying to find gcc bugs but other
    use cases has been requested too.

    Patch was tested on following architectures:
    alpha, arm, i386, x86_64, mips, sparc, sparc64, ia64, m68k

    Test was simple to do a defconfig build, apply the patch and check
    that nothing got rebuild.

    ... instead of using a CONFIG option. The config option still controls
    if the resulting executable actually has unwind information.

    This is useful to prevent compilation errors when users select
    CONFIG_STACK_UNWIND on old binutils and also allows to use
    CFI in the future for non kernel debugging applications.
