  • 346e15beb   driver core: basic infrastructure for per-module dynamic debug messages ... Browse Code »

    Base infrastructure to enable per-module debug messages.

    I've introduced CONFIG_DYNAMIC_PRINTK_DEBUG, which when enabled centralizes
    control of debugging statements on a per-module basis in one /proc file,
    currently, /dynamic_printk/modules. When, CONFIG_DYNAMIC_PRINTK_DEBUG,
    is not set, debugging statements can still be enabled as before, often by
    defining 'DEBUG' for the proper compilation unit. Thus, this patch set has no
    affect when CONFIG_DYNAMIC_PRINTK_DEBUG is not set.

    The infrastructure currently ties into all pr_debug() and dev_dbg() calls. That
    is, if CONFIG_DYNAMIC_PRINTK_DEBUG is set, all pr_debug() and dev_dbg() calls
    can be dynamically enabled/disabled on a per-module basis.

    Future plans include extending this functionality to subsystems, that define
    their own debug levels and flags.

    Usage:

    Dynamic debugging is controlled by the debugfs file,
    /dynamic_printk/modules. This file contains a list of the modules that
    can be enabled. The format of the file is as follows:


    .
    .
    .

    : Name of the module in which the debug call resides
    : whether the messages are enabled or not

    For example:

    snd_hda_intel enabled=0
    fixup enabled=1
    driver enabled=0

    Enable a module:

    $echo "set enabled=1 " > dynamic_printk/modules

    Disable a module:

    $echo "set enabled=0 " > dynamic_printk/modules

    Enable all modules:

    $echo "set enabled=1 all" > dynamic_printk/modules

    Disable all modules:

    $echo "set enabled=0 all" > dynamic_printk/modules

    Finally, passing "dynamic_printk" at the command line enables
    debugging for all modules. This mode can be turned off via the above
    disable command.

    [gkh: minor cleanups and tweaks to make the build work quietly]

    When asked by a template to include all functions from a file,
    it will also include DOC: sections wreaking havoc in the generated
    docbook file. This patch makes it use the new -no-doc-sections
    flag for kernel-doc to avoid this.

    build scripts: fixdep blows segfault on string CONFIG_MODULE seen

    The string "CONFIG_MODULE" appearing anywhere in a source file causes
    fixdep to segfault. This string appeared in the wild in the current
    mISDN sources (I think they meant CONFIG_MODULES). But it shouldn't
    segfault (esp as CONFIG_MODULE appeared in a quoted string).

  • c21b1e4d9   [PATCH] kbuild: fix dependency generation ... Browse Code »

    Commit 2e3646e51b2d6415549b310655df63e7e0d7a080 changed the way the
    split config tree is built, but failed to also adjust fixdep accordingly
    - if changing a config option from or to m, files referencing the
    respective CONFIG_..._MODULE (but not the corresponding CONFIG_...)
    didn't get rebuilt.

    The problem is that trisate symbol are represent with three different
    symbols:
    SYMBOL=n => no symbol defined
    SYMBOL=y => CONFIG_SYMBOL defined to '1'
    SYMBOL=m => CONFIG_SYMBOL_MODULE defined to '1'

    But conf_split_config do not distingush between the =y and =m case, so
    only the =y case is honoured.

    This is fixed in fixdep so when a CONFIG symbol with _MODULE is found we
    skip that part and only look for the CONFIG_SYMBOL version.

    Adds a missing exit, if the file that should be parsed couldn't be opened.
    Without it crashes with a segfault, cause the filedescriptor is accessed
    even if the file could not be opened.

  • 2e3646e51   kconfig: integrate split config into silentoldconfig ... Browse Code »

    Now that kconfig can load multiple configurations, it becomes simple to
    integrate the split config step, by simply comparing the new .config file with
    the old auto.conf (and then saving the new auto.conf). A nice side effect is
    that this saves a bit of disk space and cache, as no data needs to be read
    from or saved into the splitted config files anymore (e.g. include/config is
    now 648KB instead of 5.2MB).

  • 6176aa9ae   kbuild: consolidate command line escaping ... Browse Code »

    While the recent change to also escape # symbols when storing C-file
    compilation command lines was helpful, it should be in effect for all
    command lines, as much as the dollar escaping should be in effect for
    C-source compilation commands. Additionally, for better readability and
    maintenance, consolidating all the escaping (single quotes, dollars,
    and now sharps) was also desirable.

    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!
