  • fc2b47b55   h8300: use cc-cross-prefix instead of hardcoding h8300-unknown-linux- ... Browse Code »

    It believe it is a bad idea to hardcode a specific compiler prefix
    that may or may not be installed on a user's system. It is annoying
    when testing features that should not require compilers at all.

    For example, mrproper, headers_install, etc. should work without
    any compiler.

    They look like follows on my machine.

    $ make ARCH=h8300 mrproper
    ./scripts/gcc-version.sh: line 26: h8300-unknown-linux-gcc: command not found
    ./scripts/gcc-version.sh: line 27: h8300-unknown-linux-gcc: command not found
    make: h8300-unknown-linux-gcc: Command not found
    make: h8300-unknown-linux-gcc: Command not found
    [ a bunch of the same error messages continue ]

    $ make ARCH=h8300 headers_install
    ./scripts/gcc-version.sh: line 26: h8300-unknown-linux-gcc: command not found
    ./scripts/gcc-version.sh: line 27: h8300-unknown-linux-gcc: command not found
    make: h8300-unknown-linux-gcc: Command not found
    HOSTCC scripts/basic/fixdep
    make: h8300-unknown-linux-gcc: Command not found
    WRAP arch/h8300/include/generated/uapi/asm/kvm_para.h
    [ snip ]

    The solution is to delete this line, or to use cc-cross-prefix like
    some architectures do. I chose the latter as a moderate fixup.

    I added an alternative 'h8300-linux-' because it is available at:

  • 37c8a5faf   kbuild: consolidate Devicetree dtb build rules ... Browse Code »

    There is nothing arch specific about building dtb files other than their
    location under /arch/*/boot/dts/. Keeping each arch aligned is a pain.
    The dependencies and supported targets are all slightly different.
    Also, a cross-compiler for each arch is needed, but really the host
    compiler preprocessor is perfectly fine for building dtbs. Move the
    build rules to a common location and remove the arch specific ones. This
    is done in a single step to avoid warnings about overriding rules.

    The build dependencies had been a mixture of 'scripts' and/or 'prepare'.
    These pull in several dependencies some of which need a target compiler
    (specifically devicetable-offsets.h) and aren't needed to build dtbs.
    All that is really needed is dtc, so adjust the dependencies to only be
    dtc.

    This change enables support 'dtbs_install' on some arches which were
    missing the target.

  • d503ac531   kbuild: rename LDFLAGS to KBUILD_LDFLAGS ... Browse Code »

    Commit a0f97e06a43c ("kbuild: enable 'make CFLAGS=...' to add
    additional options to CC") renamed CFLAGS to KBUILD_CFLAGS.

    Commit 222d394d30e7 ("kbuild: enable 'make AFLAGS=...' to add
    additional options to AS") renamed AFLAGS to KBUILD_AFLAGS.

    Commit 06c5040cdb13 ("kbuild: enable 'make CPPFLAGS=...' to add
    additional options to CPP") renamed CPPFLAGS to KBUILD_CPPFLAGS.

    For some reason, LDFLAGS was not renamed.

    Using a well-known variable like LDFLAGS may result in accidental
    override of the variable.

    Kbuild generally uses KBUILD_ prefixed variables for the internally
    appended options, so here is one more conversion to sanitize the
    naming convention.

    I did not touch Makefiles under tools/ since the tools build system
    is a different world.

  • 7b291be81   arch/h8300: add a defconfig target ... Browse Code »

    Make the "defconfig" target valid for arch/h8300. Currently
    "make ARCH=h8300 defconfig" produces:

    *** Can't find default configuration "arch/h8300/defconfig"!
    ../scripts/kconfig/Makefile:87: recipe for target 'defconfig' failed

    By adding a value for KBUILD_DEFCONFIG, "make ARCH=h8300 defconfig"
    successfully produces a kernel .config file:

    *** Default configuration is based on 'edosk2674_defconfig'

    This is useful for Kconfig editing/testing.

  • 1b803a357   h8300:let the checker know that size_t is ulong ... Browse Code »

    All 64bit archs use unsigned long for size_t and most 32bit
    archs use 'unsigned int'. By default, this is what is assumed
    by sparse.

    However, on h8300 (a 32bit arch) size_t is unsigned long which
    can led sparse to emit wrong warnings.

    Fix this by passing to sparse the flag -msize-long, telling it
    that size_t is unsigned long.

  • 3bc27cdfe   h8300: Don't set CROSS_COMPILE unconditionally ... Browse Code »

    The h8300 architecture Makefile sets the CROSS_COMPILE variable to
    "h8300-unknown-linux-" unconditionally but doing that prevents the
    variable to be used if a toolchain with a different binary name is
    installed in the machine.

    So only set CROSS_COMPILE to that default if the variable has not
    been set by the user before.

  • 222d394d3   kbuild: enable 'make AFLAGS=...' to add additional options to AS ... Browse Code »

    The variable AFLAGS 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 AFLAGS with KBUILD_AFLAGS all over
    the tree.

    Patch was tested on following architectures:
    alpha, arm, i386, x86_64, mips, sparc, sparc64, ia64, m68k, s390

    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.

    Initial git repository build. I'm not bothering with the full history,
    even though we have it. We can create a separate "historical" git
    archive of that later if we want to, and in the meantime it's about
    3.2GB when imported into git - space that would just make the early
    git days unnecessarily complicated, when we don't have a lot of good
    infrastructure for it.

    Let it rip!
