  • 18c32dac7   kbuild: fix building with O=.. options ... Browse Code »

    The check introduced in commit:
    4f1127e204377cbd2a56d112d323466f668e8334 "kbuild: fix
    infinite make recursion"

    caused certain external modules not to build and
    also caused 'make targz-pkg' to fail.
    This is a minimal fix so we revert to previous
    behaviour - but we do not overwrite the Makefile
    in the top-level directory.

  • 1cacc9ab8   kbuild: fix building with redirected output. ... Browse Code »

    Jan Altenberg reported that
    building with redirected input like this failed:
    make O=dir oldconfig bzImage < /dev/null

    The problem were caused by a make silentoldconfig being
    run before oldconfig and with a non-recent .config the build
    failed because silentoldconfig requires non-redirected stdin.

    Silentoldconfig was run as a side-effect of having the
    top-level Makefile re-made by make.
    Introducing an empty rule for the top-level Makefile
    (and Kbuild.include) fixed the issue.

  • 80ef88d6d   x86: simplify "make ARCH=x86" and fix kconfig all.config ... Browse Code »

    Simplify "make ARCH=x86" and fix kconfig so we again
    can set 64BIT in all.config.

    For a fix the diffstat is nice:
    6 files changed, 3 insertions(+), 36 deletions(-)

    The patch reverts these commits:
    0f855aa64b3f63d35a891510cf7db932a435c116
    -> kconfig: add helper to set config symbol from environment variable

    2a113281f5cd2febbab21a93c8943f8d3eece4d3
    -> kconfig: use $K64BIT to set 64BIT with all*config targets

    Roman Zippel pointed out that kconfig supported string
    compares so the additional complexity introduced by the
    above two patches were not needed.

    With this patch we have following behaviour:

    # make {allno,allyes,allmod,rand}config [ARCH=...]
    option \ host arch | 32bit | 64bit
    =====================================================
    ./. | 32bit | 64bit
    ARCH=x86 | 32bit | 32bit
    ARCH=i386 | 32bit | 32bit
    ARCH=x86_64 | 64bit | 64bit

    The general rule are that ARCH= and native architecture
    takes precedence over the configuration.
    So make ARCH=i386 [whatever] will always build a 32-bit
    kernel no matter what the configuration says.
    The configuration will be updated to 32-bit if it was
    configured to 64-bit and the other way around.

    This behaviour is consistent with previous behaviour so
    no suprises here.

    make ARCH=x86 will per default result in a 32-bit kernel
    but as the only ARCH= value x86 allow the user to select
    between 32-bit and 64-bit using menuconfig.

  • daa93fab8   x86: enable "make ARCH=x86" ... Browse Code »

    After unification of the Kconfig files and
    introducing K64BIT support in kconfig
    it required only trivial changes to enable
    "make ARCH=x86".

    With this patch you can build for x86_64 in several ways:
    1) make ARCH=x86_64
    2) make ARCH=x86 K64BIT=y
    3) make ARCH=x86 menuconfig
    => select 64-bit

    Likewise for i386 with the addition that
    i386 is default is you say ARCH=x86.

    For x86 ARCH may say i386 or x86_64 and soon x86.
    Rely on CONFIG_X64_32 to select between 32/64 or just

  • 69ee0b352   kbuild: do not pick up CFLAGS from the environment ... Browse Code »
    43

    Too many people have CFLAGS set to support building userspace.
    And now Kbuild picks up CFLAGS this caused troubles.

    Although people should realise that setting CFLAGS has
    a 'global' effect the impact on the kernel build is a suprise.
    So change kbuild to pick up value from KCFLAGS that is
    much less used.

    When kbuild pick up a value it will warn like this:
    Makefile:544: "WARNING: Appending $KCFLAGS (-O3) from environment to kernel $CFLAGS"

    The patch is big. Really big. You just won't believe how vastly hugely
    mindbogglingly big it is. I mean you may think it's a long way down the
    road to the chemist, but that's just peanuts to how big the patch from
    2.6.23 is.

    But it's all good.

    depmod from module-init-tools 3.3-pre2 are reported
    to work fine in cross build.
    depmod from module-init-tools 3.1-pre5 are known to SEGV

    Do not workaround older module-init-tools bugs here.
    The right fix is for users to upgrade module-init-tools.

    make vmlinux would delete the content of $(MODVERDIR)
    equals .tmp_versions. This caused a subsequent
    make modules_install to fail.

    Fix it so we clean the directory only for the
    modules build - but we still unconditionally create it so
    we can do:
    make dir/file.ko
    without a preceeding make modules.

    When building a specific module before doing a total kernel
    build it failed because $(MORVERDIR) were missing.
    Creating the MODVERDIR explicit (independent of KBUILD_MODULES)
    fixed this. As a side-effect the MODVERDIR will be created
    also for a non-module build - but no harm done by that.

  • 50a8ec31c   kbuild: disable depmod in cross-compile kernel build ... Browse Code »

    When building embedded systems in a cross-compile environment and
    populating a target's file system image, we don't want to run the
    depmod on the host as we may be building for a completely different
    architecture. Since there's no such thing as a cross-depmod, we
    just disable running depmod in the cross-compile case and we just
    run depmod on the target at bootup.

    Inspired by patches from Christian, Armin and Deepak.

  • fc333b2df   kbuild: check asm symlink when building a kernel ... Browse Code »

    We often hit the situation where the asm symlink
    in include/ points to the wrong architecture.
    In 9 out of 10 cases thats because we forgot to set
    ARCH but sometimes we just reused the same tree
    for another ARCH. For the merged x86 tree we need
    to create a new symlink but this is not obvious.
    So with the following patch we check if the symlink
    points to the correct architecture and error
    out if this is not the case.
