  • ec7748b59   ide: introduce HAVE_IDE ... Browse Code »

    To allow flexible configuration of IDE introduce HAVE_IDE.
    All archs except arm, um and s390 unconditionally select it.
    For arm the actual configuration determine if IDE is supported.

    This is a step towards introducing drivers/Kconfig for arm.

  • b0b933c08   aout: mark arches that support A.OUT format ... Browse Code »

    Mark arches that support A.OUT format by including the following in their
    master Kconfig files:

    config ARCH_SUPPORTS_AOUT
    def_bool y

    This should also be set if the arch provides compatibility A.OUT support for
    an older arch, for instance x86_64 for i386 or sparc64 for sparc.

    I've guessed at which arches don't, based on comments in the code, however I'm
    sure that some of the ones I've marked as 'yes' actually should be 'no'.

  • 42d4b839c   Add HAVE_OPROFILE ... Browse Code »

    Linus:
    On the per-architecture side, I do think it would be better to *not* have
    internal architecture knowledge in a generic file, and as such a line like

    depends on X86_32 || IA64 || PPC || S390 || SPARC64 || X86_64 || AVR32

    really shouldn't exist in a file like kernel/Kconfig.instrumentation.

    It would be much better to do

    depends on ARCH_SUPPORTS_KPROBES

    in that generic file, and then architectures that do support it would just
    have a

    bool ARCH_SUPPORTS_KPROBES
    default y

    in *their* architecture files. That would seem to be much more logical,
    and is readable both for arch maintainers *and* for people who have no
    clue - and don't care - about which architecture is supposed to support
    which interface...

    Changelog:

    Actually, I know I gave this as the magic incantation, but now that I see
    it, I realize that I should have told you to just use

    config ARCH_SUPPORTS_KPROBES
    def_bool y

    instead, which is a bit denser.

    We seem to use both kinds of syntax for these things, but this is really
    what "def_bool" is there for...

    Changelog :

    - Moving to HAVE_*.
    - Add AVR32 oprofile.

  • 95c354fe9   spinlock: lockbreak cleanup ... Browse Code »

    The break_lock data structure and code for spinlocks is quite nasty.
    Not only does it double the size of a spinlock but it changes locking to
    a potentially less optimal trylock.

    Put all of that under CONFIG_GENERIC_LOCKBREAK, and introduce a
    __raw_spin_is_contended that uses the lock data itself to determine whether
    there are waiters on the lock, to be used if CONFIG_GENERIC_LOCKBREAK is
    not set.

    Rename need_lockbreak to spin_needbreak, make it use spin_is_contended to
    decouple it from the spinlock implementation, and make it typesafe (rwlocks
    do not have any need_lockbreak sites -- why do they even get bloated up
    with that break_lock then?).

  • 09cadedbd   Combine instrumentation menus in kernel/Kconfig.instrumentation ... Browse Code »

    Quoting Randy:

    "It seems sad that this patch sources Kconfig.marker, a 7-line file,
    20-something times. Yes, you (we) don't want to put those 7 lines into
    20-something different files, so sourcing is the right thing.

    However, what you did for avr32 seems more on the right track to me: make
    _one_ Instrumentation support menu that includes PROFILING, OPROFILE, KPROBES,
    and MARKERS and then use (source) that in all of the arches."

  • f0d1b0b30   [PATCH] LOG2: Implement a general integer log2 facility in the kernel ... Browse Code »

    This facility provides three entry points:

    ilog2() Log base 2 of unsigned long
    ilog2_u32() Log base 2 of u32
    ilog2_u64() Log base 2 of u64

    These facilities can either be used inside functions on dynamic data:

    int do_something(long q)
    {
    ...;
    y = ilog2(x)
    ...;
    }

    Or can be used to statically initialise global variables with constant values:

    unsigned n = ilog2(27);

    When performing static initialisation, the compiler will report "error:
    initializer element is not constant" if asked to take a log of zero or of
    something not reducible to a constant. They treat negative numbers as
    unsigned.

    When not dealing with a constant, they fall back to using fls() which permits
    them to use arch-specific log calculation instructions - such as BSR on
    x86/x86_64 or SCAN on FRV - if available.

  • c80d79d74   [PATCH] Configurable NODES_SHIFT ... Browse Code »

    Current implementations define NODES_SHIFT in include/asm-xxx/numnodes.h for
    each arch. Its definition is sometimes configurable. Indeed, ia64 defines 5
    NODES_SHIFT values in the current git tree. But it looks a bit messy.

    SGI-SN2(ia64) system requires 1024 nodes, and the number of nodes already has
    been changeable by config. Suitable node's number may be changed in the
    future even if it is other architecture. So, I wrote configurable node's
    number.

    This patch set defines just default value for each arch which needs multi
    nodes except ia64. But, it is easy to change to configurable if necessary.

    On ia64 the number of nodes can be already configured in generic ia64 and SN2
    config. But, NODES_SHIFT is defined for DIG64 and HP'S machine too. So, I
    changed it so that all platforms can be configured via CONFIG_NODES_SHIFT. It
    would be simpler.

  • a08b6b796   [PATCH] Kconfig fix (BLK_DEV_FD dependencies) ... Browse Code »

    Sanitized and fixed floppy dependencies: split the messy dependencies for
    BLK_DEV_FD by introducing a new symbol (ARCH_MAY_HAVE_PC_FDC), making
    BLK_DEV_FD depend on that one and taking declarations of ARCH_MAY_HAVE_PC_FDC
    to arch/*/Kconfig. While we are at it, fixed several obvious cases when
    BLK_DEV_FD should have been excluded (architectures lacking asm/floppy.h
    are *not* going to have floppy.c compile, let alone work).

    If you can come up with better name for that ("this architecture might
    have working PC-compatible floppy disk controller"), you are more than
    welcome - just s/ARCH_MAY_HAVE_PC_FDC/your_prefered_name/g in the patch

    To implement this all architectures has to source "net/Kconfig" before
    drivers/*/Kconfig in their Kconfig file. This change has been
    implemented for all architectures.

    Device drivers for ordinary NIC's are still to be found

  • 5cae841b1   [PATCH] ISA DMA Kconfig fixes - part 1 ... Browse Code »

    A bunch of drivers use ISA DMA helpers or their equivalents for
    platforms that have ISA with different DMA controller (a lot of ARM
    boxen). Currently there is no way to put such dependency in Kconfig -
    CONFIG_ISA is not it (e.g. it is not set on platforms that have no ISA
    slots, but have on-board devices that pretend to be ISA ones).

    New symbol added - ISA_DMA_API. Set when we have functional
    enable_dma()/set_dma_mode()/etc. set of helpers. Next patches in the
    series will add missing dependencies for drivers that need them.

    I'm very carefully staying the hell out of the recurring flamefest on
    what exactly CONFIG_ISA would mean in ideal world - added symbol has a
    well-defined meaning and for now I really want to treat it as completely
    independent from the mess around CONFIG_ISA.
