    scripts/Makefile.clean treats absolute path specially, but
    $(objtree)/debian is no longer an absolute path since 7e1c0477 (kbuild:
    Use relative path for $(objtree). Work around this by checking if the
    path starts with $(objtree)/.

    Makefile.clean includes Kbuild.include since commit 371fdc77
    (kbuild: collect shorthands into scripts/Kbuild.include), so there is no
    need for a local copy.

    The shorthand "clean" is defined in both the top Makefile and
    scripts/Makefile.clean. Likewise, the "hdr-inst" is defined in
    both the top Makefile and scripts/Makefile.headersinst.

    To reduce code duplication, this commit collects them into
    scripts/Kbuild.include like the "build" and "modbuiltin" shorthands.
    It requires scripts/Makefile.clean to include scripts/Kbuild.include,
    but its impact on the performance of "make clean" should be
    negligible.

    $(if $(KBUILD_SRC),$(srctree)/) was a useful strategy
    to omit a long absolute path for in-source-tree build
    prior to commit 890676c65d699db3ad82e7dddd0cf8fb449031af
    (kbuild: Use relative path when building in the source tree).

    Now $(srctree) is "." when building in the source tree.
    It would not be annoying to add "$(srctree)/" all the time.

    Kconfig never defines CONFIG_* as 'n'.
    Now obj-n is only used in firmware/Makefile and it can be
    replaced with obj-. No makefile uses lib-n.

    Let's rip off obj-n and lib-n.

    Commit 7d3cc8b tried to keep bounds.h and asm-offsets.h during make
    clean by filtering these out of $(clean-files), but they are listed in
    $(targets) and $(always) and thus removed automatically. Introduce a new
    $(no-clean-files) variable to really skip such files in Makefile.clean.

    These checks has been present for several kernel releases (> 5).
    So lets just get rid of them.
    With this we no longer check for use of:
    EXTRA_TARGETS, O_TARGET, L_TARGET, list-multi, export-objs

    There were three remaining in-tree users of O_TARGET in some
    unmaintained sh64 code - mail sent to the maintainer + list.

  • 4f1933620   kbuild: change kbuild to not rely on incorrect GNU make behavior ... Browse Code »

    The kbuild system takes advantage of an incorrect behavior in GNU make.
    Once this behavior is fixed, all files in the kernel rebuild every time,
    even if nothing has changed. This patch ensures kbuild works with both
    the incorrect and correct behaviors of GNU make.

    For more details on the incorrect behavior, see:

    http://lists.gnu.org/archive/html/bug-make/2006-03/msg00003.html

    Changes in this patch:
    - Keep all targets that are to be marked .PHONY in a variable, PHONY.
    - Add .PHONY: $(PHONY) to mark them properly.
    - Remove any $(PHONY) files from the $? list when determining whether
    targets are up-to-date or not.

  • db8c1a7b2   kbuild: fix building external modules ... Browse Code »

    kbuild failed to locate Makefile for external modules.
    This brought to my attention how the variables for directories
    have different values in different usage scenarios.

    Different kbuild usage scenarios:
    make - plain make in same directory where kernel source lives
    make O= - kbuild is told to store output files in another directory
    make M= - building an external module
    make O= M= - building an external module with kernel output seperate from src

    Value assigned to the different variables:

    |$(src) |$(obj) |$(srctree) |$(objtree)
    make |reldir to k src |as src |abs path to k src |abs path to k src
    make O= |reldir to k src |as src |abs path to k src |abs path to output dir
    make M= |abs path to src |as src |abs path to k src |abs path to k src
    make O= M= |abs path to src |as src |abs path to k src |abs path to k output

    path to kbuild file:

    make | $(srctree)/$(src), $(src)
    make O= | $(srctree)/$(src)
    make M= | $(src)
    make O= M= | $(src)

    From the table above it can be seen that the only good way to find the
    home directory of the kbuild file is to locate the one of the two variants
    that is an absolute path. If $(src) is an absolute path (starts with /)
    then use it, otherwise prefix $(src) with $(srctree).

    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!
