    commit b1fbfcb4a20949df08dd995927cdc5ad220c128d upstream.

    Commit 2dffd23f81a3 ("kbuild: make single target builds much faster")
    made the situation much better.

    To improve it even more, apply the similar idea to the top Makefile.
    Trim unrelated directories from build-dirs.

    The single build code must be moved above the 'descend' target.

    commit 35e046a203ee3bc8ba9ae3561b50de02646dfb81 upstream.

    When single-build is set, everything in $(MAKECMDGOALS) is a single
    target. You can use $(MAKECMDGOALS) to list out the single targets.

  • ecd77a326   kbuild: move headers_check rule to usr/include/Makefile ... Browse Code »

    commit 7ecaf069da52e472d393f03e79d721aabd724166 upstream.

    Currently, some sanity checks for uapi headers are done by
    scripts/headers_check.pl, which is wired up to the 'headers_check'
    target in the top Makefile.

    It is true compiling headers has better test coverage, but there
    are still several headers excluded from the compile test. I like
    to keep headers_check.pl for a while, but we can delete a lot of
    code by moving the build rule to usr/include/Makefile.

  • ef134d8b4   kbuild: remove header compile test ... Browse Code »

    commit fcbb8461fd2376ba3782b5b8bd440c929b8e4980 upstream.

    There are both positive and negative options about this feature.
    At first, I thought it was a good idea, but actually Linus stated a
    negative opinion (https://lkml.org/lkml/2019/9/29/227). I admit it
    is ugly and annoying.

    The baseline I'd like to keep is the compile-test of uapi headers.
    (Otherwise, kernel developers have no way to ensure the correctness
    of the exported headers.)

    I will maintain a small build rule in usr/include/Makefile.
    Remove the other header test functionality.

  • 80591e61a   kbuild: tell sparse about the $ARCH ... Browse Code »

    Sparse uses the same executable for all archs and uses flags
    like -m64, -mbig-endian or -D__arm__ for arch-specific parameters.
    But Sparse also uses value from the host machine used to build
    Sparse as default value for the target machine.

    This works, of course, well for native build but can create
    problems when cross-compiling, like defining both '__i386__'
    and '__arm__' when cross-compiling for arm on a x86-64 machine.

    Fix this by explicitely telling sparse the target architecture.

    …/git/shuah/linux-kselftest

    Pull Kselftest fixes from Shuah Khan:
    "Fixes for existing tests and the framework.

    Cristian Marussi's patches add the ability to skip targets (tests) and
    exclude tests that didn't build from run-list. These patches improve
    the Kselftest results. Ability to skip targets helps avoid running
    tests that aren't supported in certain environments. As an example,
    bpf tests from mainline aren't supported on stable kernels and have
    dependency on bleeding edge llvm. Being able to skip bpf on systems
    that can't meet this llvm dependency will be helpful.

    Kselftest can be built and installed from the main Makefile. This
    change help simplify Kselftest use-cases which addresses request from
    users.

    Kees Cook added per test timeout support to limit individual test
    run-time"

    * tag 'linux-kselftest-5.4-rc3' of git://git.kernel.org/pub/scm/linux/kernel/git/shuah/linux-kselftest:
    selftests: watchdog: Add command line option to show watchdog_info
    selftests: watchdog: Validate optional file argument
    selftests/kselftest/runner.sh: Add 45 second timeout per test
    kselftest: exclude failed TARGETS from runlist

  • d85103ac7   kbuild: fix build error of 'make nsdeps' in clean tree ... Browse Code »

    Running 'make nsdeps' in a clean source tree fails as follows:

    $ make -s clean; make -s defconfig; make nsdeps
    [ snip ]
    awk: fatal: cannot open file `init/modules.order' for reading (No such file or directory)
    make: *** [Makefile;1307: modules.order] Error 2
    make: *** Deleting file 'modules.order'
    make: *** Waiting for unfinished jobs....

    The cause of the error is 'make nsdeps' does not build modules at all.
    Set KBUILD_MODULES to fix it.
