  • 052ad2749   kbuild: Add support for an "archheaders" target ... Browse Code »

    Add support for an "archheaders" target. This target can generate
    files that need to be installed for user space by "make
    headers_install" or "make headers_install_all".

    In order to support "make headers_install_all", it must be able to run
    without the tree having to be configured first.

  • 8417da6f2   kbuild: Fix passing -Wno-* options to gcc 4.4+ ... Browse Code »

    Starting with 4.4, gcc will happily accept -Wno- in the
    cc-option test and complain later when compiling a file that has some
    other warning. This rather unexpected behavior is intentional as per
    http://gcc.gnu.org/PR28322, so work around it by testing for support of
    the opposite option (without the no-). Introduce a new Makefile function
    cc-disable-warning that does this and update two uses of cc-option in
    the toplevel Makefile.

  • d8ecc5cd8   kbuild: asm-generic support ... Browse Code »

    There is an increasing amount of header files
    shared between individual architectures in asm-generic.
    To avoid a lot of dummy wrapper files that just
    include the corresponding file in asm-generic provide
    some basic support in kbuild for this.

    With the following patch an architecture can maintain
    a list of files in the file arch/$(ARCH)/include/asm/Kbuild

    To use a generic file just add:

    generic-y +=

    For each file listed kbuild will generate the necessary
    wrapper in arch/$(ARCH)/include/generated/asm.

    When installing userspace headers a wrapper is likewise created.

    The original inspiration for this came from the unicore32
    patchset - although a different method is used.

    The patch includes several improvements from Arnd Bergmann.
    Michael Marek contributed Makefile.asm-generic.

    Remis Baima did an intial implementation along to achive
    the same - see https://patchwork.kernel.org/patch/13352/

  • aab94339c   of: Add support for linking device tree blobs into vmlinux ... Browse Code »

    This patch adds support for linking device tree blob(s) into
    vmlinux. Modifies asm-generic/vmlinux.lds.h to add linking
    .dtb sections into vmlinux. To maintain compatiblity with the of/fdt
    driver code platforms MUST copy the blob to a non-init memory location
    before the kernel frees the .init.* sections in the image.

    Modifies scripts/Makefile.lib to add a kbuild command to
    compile DTS files to device tree blobs and a rule to create objects to
    wrap the blobs for linking.

    STRUCT_ALIGNMENT is defined in vmlinux.lds.h for use in the rule to
    create wrapper objects for the dtb in Makefile.lib. The
    STRUCT_ALIGN() macro in vmlinux.lds.h is modified to use the
    STRUCT_ALIGNMENT definition.

    The DTB's are placed on 32 byte boundries to allow parsing the blob
    with driver/of/fdt.c during early boot without having to copy the blob
    to get the structure alignment GCC expects.

    A DTB is linked in by adding the DTB object to the list of objects to
    be linked into vmlinux in the archtecture specific Makefile using
    obj-y += foo.dtb.o

  • 80c00ba94   kbuild: allow assignment to {A,C}FLAGS_KERNEL on the command line ... Browse Code »

    It is now possible to assign options to AS and CC
    on the command line - which is only used for built-in code.

    {A,C}FLAGS_KERNEL was used both in the top-level Makefile
    in the arch makefiles, thus users had no way to specify
    additional options to AS, CC without overriding
    the original value.

    Introduce a new set of variables KBUILD_{A,C}FLAGS_KERNEL
    that is used by arch specific files and free up
    {A,C}FLAGS_KERNEL so they can be assigned on
    the command line.

    All arch Makefiles that used the old variables has been updated.

    It is now possible to assign options to AS, CC and LD
    on the command line - which is only used when building modules.

    {A,C,LD}FLAGS_MODULE was all used both in the top-level Makefile
    in the arch makefiles, thus users had no way to specify
    additional options to AS, CC, LD when building modules
    without overriding the original value.

    All arch Makefiles that used the old variables has been updated.

    Note: Previously we had a MODFLAGS variable for both
    AS and CC. But in favour of consistency this was dropped.
    So in some cases arch Makefile has one assignmnet replaced by
    two assignmnets.

    Note2: MODFLAGS was not documented and is dropped
    without any notice. I do not expect much/any breakage
    from this.

    $(targets) and $(always) and thus removed automatically. Introduce a new

  • 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.

    CROSS_COMPILE := $(call cc-cross-prefix, m68k-linux-gnu- m68k-linux-)

  • 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

    Patch was tested on following architectures:

    Test was simple to do a defconfig build, apply the patch and check
