  • cf4db2597   ftrace: Rename config option HAVE_C_MCOUNT_RECORD to HAVE_C_RECORDMCOUNT ... Browse Code »

    The config option used by archs to let the build system know that
    the C version of the recordmcount works for said arch is currently
    called HAVE_C_MCOUNT_RECORD which enables BUILD_C_RECORDMCOUNT. To
    be more consistent with the name that all archs may use, it has been
    renamed to HAVE_C_RECORDMCOUNT. This will be less confusing since
    we are building a C recordmcount and not a mcount_record.

  • 72441cb1f   ftrace/x86: Add support for C version of recordmcount ... Browse Code »

    This patch adds the support for the C version of recordmcount and
    compile times show ~ 12% improvement.

    After verifying this works, other archs can add:

    HAVE_C_MCOUNT_RECORD

    in its Kconfig and it will use the C version of recordmcount
    instead of the perl version.

  • bf5438fca   jump label: Base patch for jump label ... Browse Code »

    base patch to implement 'jump labeling'. Based on a new 'asm goto' inline
    assembly gcc mechanism, we can now branch to labels from an 'asm goto'
    statment. This allows us to create a 'no-op' fastpath, which can subsequently
    be patched with a jump to the slowpath code. This is useful for code which
    might be rarely used, but which we'd like to be able to call, if needed.
    Tracepoints are the current usecase that these are being implemented for.

  • 80c00ba94   kbuild: allow assignment to {A,C}FLAGS_KERNEL on the command line ... Browse Code »

    It is now possible to assign options to AS and CC
    on the command line - which is only used for built-in code.

    {A,C}FLAGS_KERNEL was used both in the top-level Makefile
    in the arch makefiles, thus users had no way to specify
    additional options to AS, CC without overriding
    the original value.

    Introduce a new set of variables KBUILD_{A,C}FLAGS_KERNEL
    that is used by arch specific files and free up
    {A,C}FLAGS_KERNEL so they can be assigned on
    the command line.

    All arch Makefiles that used the old variables has been updated.

    It is now possible to assign options to AS, CC and LD
    on the command line - which is only used when building modules.

    {A,C,LD}FLAGS_MODULE was all used both in the top-level Makefile
    in the arch makefiles, thus users had no way to specify
    additional options to AS, CC, LD when building modules
    without overriding the original value.

    that is used by arch specific files and free up
    {A,C,LD}FLAGS_MODULE so they can be assigned on
    the command line.

    All arch Makefiles that used the old variables has been updated.

    Note: Previously we had a MODFLAGS variable for both
    AS and CC. But in favour of consistency this was dropped.
    So in some cases arch Makefile has one assignmnet replaced by
    two assignmnets.

    Note2: MODFLAGS was not documented and is dropped
    without any notice. I do not expect much/any breakage
    from this.

  • d6f4ceb79   Kbuild: Add option to set -femit-struct-debug-baseonly ... Browse Code »

    Newer gcc has a -femit-struct-debug-baseonly option that dramatically
    reduces the size of object files with debug info. What it does
    is to only emit type information for structures when the structures
    are defined in the same file or in a header file.

    This means the type information for most headers are not included.
    This is not good when the type information is actually
    needed (e.g. with kgdb or systemtap)

    But often kernel hackers only care about line numbers and don't
    need all the type information anyways. In this case setting
    the option can be a big win:

    A build dir for a specific x86-64 configuration with gcc 4.5
    shrunk from 2.3G to 1.2G. The compilation was also nearly a minute
    faster.

  • 09155120c   kbuild: Clean up and speed up the localversion logic ... Browse Code »

    Now that we run scripts/setlocalversion during every build, it makes
    sense to move all the localversion logic there. This cleans up the
    toplevel Makefile and also makes sure that the script is called only
    once in 'make prepare' (previously, it would be called every time due to
    a variable expansion in an ifneq statement). No user-visible change is
    intended, unless one runs the setlocalversion script directly.

  • d5eda75f3   kbuild: fix LOCALVERSION handling to match description ... Browse Code »

    In the commit below the version string handling was modified, adding
    a '+' where no other version information was supplied:

    commit 85a256d8e0116c8f5ad276730830f5d4d473344d
    Author: David Rientjes
    Date: Wed Jan 13 13:01:05 2010 -0800

    From the commit the intent was as below:

    - when CONFIG_LOCALVERSION_AUTO is disabled, a `+' is appended if the
    repository has been revised beyond a tagged commit and LOCALVERSION=
    was not passed to "make".

    However if the user supplies an empty LOCALVERSION on the command line
    the plus suffix is still added. This form is useful in the case where
    the build environment knows that the version as specified is correct and
    complete but does not correspond to a specific tag.

    This patch changes the implementation to match the documentation
    such that specifying LOCALVERSION= on the build line is sufficient
    to suppress any suffix.
