  • e6ac89fab   kbuild: Correctly deal with make options which contain an "s" ... Browse Code »

    When using remake, which is based on gnumake, if you invoke
    an example build as shown below, the build will become silent
    due to the top level make file incorrectly guessing that
    the end user wants a silent build because an argument that
    contained an "s" was used. Here are two examples one with remake
    and one with straight gnumake.

    remake --no-extended-errors
    make --warn-undefined-variables

    Fix up the top level Makefile to use filter to parse the options
    that mean silent instead of findstring catching other random
    arguments containing an "s".

    Commit 3d64b44 introduced an empty file under
    arch/arm/mach-zynq/board_dt.c. While this was not intended and the file
    was removed from the tree by a later commit, we really should only match
    junk files by known name patterns and not their size.

    43

    Replace the config_is_*() macros with a variant that allows for grepping
    for usage of CONFIG_* options in the code. Usage:

    if (IS_ENABLED(CONFIG_NUMA))

    or

    #if IS_ENABLED(CONFIG_NUMA)

    The IS_ENABLED() macro evaluates to 1 if the argument is set (to either 'y'
    or 'm'), IS_BUILTIN() tests if the option is 'y' and IS_MODULE() test if
    the option is 'm'. Only boolean and tristate options are supported.

    Hopefully by the time the final 3.0 is out, we'll have that extra zero

    With this change, you can (and should) build with ARCH=tilepro for the
    current 32-bit chips. Building with ARCH=tile continues to work, but
    we've renamed the defconfig file to tilepro_defconfig for consistency.

  • 18aecc2b6   arch/tile: finish enabling support for TILE-Gx 64-bit chip ... Browse Code »

    This support was partially present in the existing code (look for
    "__tilegx__" ifdefs) but with this change you can build a working
    kernel using the TILE-Gx toolchain and ARCH=tilegx.

    Most of these files are new, generally adding a foo_64.c file
    where previously there was just a foo_32.c file.

    The ARCH=tilegx directive redirects to arch/tile, not arch/tilegx,
    using the existing SRCARCH mechanism in the top-level Makefile.

    Changes to existing files:

    - and changed to factor the
    include of in the common header.

    - and arch/tile/kernel/compat.c changed to remove
    the "const" markers I had put on compat_sys_execve() when trying
    to match some recent similar changes to the non-compat execve.
    It turns out the compat version wasn't "upgraded" to use const.

    - and were
    previously included accidentally, with the 32-bit contents. Now
    they have the proper 64-bit contents.

    Finally, I had to hack the existing hacky drivers/input/input-compat.h
    to add yet another "#ifdef" for INPUT_COMPAT_TEST (same as x86_64).

    According to Documentation/Changes, the kernel should be buildable with
    GNU make 3.80+. Commit 88d7be031f9f975bb3f50a0b5ef3796a671e7edf (kbuild:
    Use a single clean rule for kernel and external modules) introduced the
    "$(or" construct, which requires make 3.81. This causes "make clean" to
    malfunction when it is used with external modules.

    Replace "$(or" with an equivalent "$(if" expression, to restore backward
    compatibility.
