  • 90ac086bc   Makefile: include arch/*/include/generated/uapi before .../generated ... Browse Code »

    The introduction of the uapi directories in v3.7-rc1 moved some of the
    generated headers from arch/*/include/generated to the uapi directory,
    keeping the #include directives intact.

    This creates a problem when bisecting, because the unversioned files are
    not cleaned automatically by git and the compiler might include stale
    headers as a result. Instead of cleaning them in the Makefiles, promote
    arch/*/include/generated/uapi in the search path. Under normal
    circumstances, there is no overlap between this uapi subdirectory and
    its parent, so the include choices remain the same. We keep
    arch/*/include/generated/uapi in the USERINCLUDE variable so that it is
    usable standalone.

    Note that we cannot completely swap the order of the uapi and
    kernel-only directories, since the headers in include/uapi/asm-generic
    are meant to be wrapped by their include/asm-generic counterparts when
    building kernel code.

    26

    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.

  • 51b97e354   kernel: use the gnu89 standard explicitly ... Browse Code »

    Sasha Levin reports:
    "gcc5 changes the default standard to c11, which makes kernel build
    unhappy

    Explicitly define the kernel standard to be gnu89 which should keep
    everything working exactly like it was before gcc5"

    There are multiple small issues with the new default, but the biggest
    issue seems to be that the old - and very useful - GNU extension to
    allow a cast in front of an initializer has gone away.

    Patch updated by Kirill:
    "I'm pretty sure all gcc versions you can build kernel with supports
    -std=gnu89. cc-option is redunrant.

    We also need to adjust HOSTCFLAGS otherwise allmodconfig fails for me"

    Note by Andrew Pinski:
    "Yes it was reported and both problems relating to this extension has
    been added to gnu99 and gnu11. Though there are other issues with the
    kernel dealing with extern inline have different semantics between
    gnu89 and gnu99/11"

    End result: we may be able to move up to a newer stdc model eventually,
    but right now the newer models have some annoying deficiencies, so the
    traditional "gnu89" model ends up being the preferred one.

  • beb50df39   kbuild: handle module compression while running 'make modules_install'. ... Browse Code »

    Since module-init-tools (gzip) and kmod (gzip and xz) support compressed
    modules, it could be useful to include a support for compressing modules
    right after having them installed. Doing this in kbuild instead of per
    distro can permit to make this kind of usage more generic.

    This patch add a Kconfig entry to "Enable loadable module support" menu
    and let you choose to compress using gzip (default) or xz.

    Both gzip and xz does not used any extra -[1-9] option since Andi Kleen
    and Rusty Russell prove no gain is made using them. gzip is called with -n
    argument to avoid storing original filename inside compressed file, that
    way we can save some more bytes.

    On a v3.16 kernel, 'make allmodconfig' generated 4680 modules for a
    total of 378MB (no strip, no sign, no compress), the following table
    shows observed disk space gain based on the allmodconfig .config :

    | time |
    +-------------+-----------------+
    | manual .ko | make | size | percent
    | compression | modules_install | | gain
    +-------------+-----------------+------+--------
    - | | 18.61s | 378M |
    GZIP | 3m16s | 3m37s | 102M | 73.41%
    XZ | 5m22s | 5m39s | 77M | 79.83%

    The gain for restricted environnement seems to be interesting while
    uncompress can be time consuming but happens only while loading a module,
    that is generally done only once.

    This is fully compatible with signed modules while the signed module is
    compressed. module-init-tools or kmod handles decompression
    and provide to other layer the uncompressed but signed payload.
