  • a67ff6a54   ALSA: module_param: make bool parameters really bool ... Browse Code »

    module_param(bool) used to counter-intuitively take an int. In
    fddd5201 (mid-2009) we allowed bool or int/unsigned int using a messy
    trick.

    It's time to remove the int/unsigned int option. For this version
    it'll simply give a warning, but it'll break next kernel version.

  • 5a0e3ad6a   include cleanup: Update gfp.h and slab.h includes to prepare for breaking implic… ... Browse Code »

    …it slab.h inclusion from percpu.h

    percpu.h is included by sched.h and module.h and thus ends up being
    included when building most .c files. percpu.h includes slab.h which
    in turn includes gfp.h making everything defined by the two files
    universally available and complicating inclusion dependencies.

    percpu.h -> slab.h dependency is about to be removed. Prepare for
    this change by updating users of gfp and slab facilities include those
    headers directly instead of assuming availability. As this conversion
    needs to touch large number of source files, the following script is
    used as the basis of conversion.

    http://userweb.kernel.org/~tj/misc/slabh-sweep.py

    The script does the followings.

    * Scan files for gfp and slab usages and update includes such that
    only the necessary includes are there. ie. if only gfp is used,
    gfp.h, if slab is used, slab.h.

    * When the script inserts a new include, it looks at the include
    blocks and try to put the new include such that its order conforms
    to its surrounding. It's put in the include block which contains
    core kernel includes, in the same order that the rest are ordered -
    alphabetical, Christmas tree, rev-Xmas-tree or at the end if there
    doesn't seem to be any matching order.

    * If the script can't find a place to put a new include (mostly
    because the file doesn't have fitting include block), it prints out
    an error message indicating which .h file needs to be added to the
    file.

    The conversion was done in the following steps.

    1. The initial automatic conversion of all .c files updated slightly
    over 4000 files, deleting around 700 includes and adding ~480 gfp.h
    and ~3000 slab.h inclusions. The script emitted errors for ~400
    files.

    2. Each error was manually checked. Some didn't need the inclusion,
    some needed manual addition while adding it to implementation .h or
    embedding .c file was more appropriate for others. This step added
    inclusions to around 150 files.

    3. The script was run again and the output was compared to the edits
    from #2 to make sure no file was left behind.

    4. Several build tests were done and a couple of problems were fixed.
    e.g. lib/decompress_*.c used malloc/free() wrappers around slab
    APIs requiring slab.h to be added manually.

    5. The script was run on all .h files but without automatically
    editing them as sprinkling gfp.h and slab.h inclusions around .h
    files could easily lead to inclusion dependency hell. Most gfp.h
    inclusion directives were ignored as stuff from gfp.h was usually
    wildly available and often used in preprocessor macros. Each
    slab.h inclusion directive was examined and added manually as
    necessary.

    6. percpu.h was updated not to include slab.h.

    7. Build test were done on the following configurations and failures
    were fixed. CONFIG_GCOV_KERNEL was turned off for all tests (as my
    distributed build env didn't work with gcov compiles) and a few
    more options had to be turned off depending on archs to make things
    build (like ipr on powerpc/64 which failed due to missing writeq).

    * x86 and x86_64 UP and SMP allmodconfig and a custom test config.
    * powerpc and powerpc64 SMP allmodconfig
    * sparc and sparc64 SMP allmodconfig
    * ia64 SMP allmodconfig
    * s390 SMP allmodconfig
    * alpha SMP allmodconfig
    * um on x86_64 SMP allmodconfig

    8. percpu.h modifications were reverted so that it could be applied as
    a separate patch and serve as bisection point.

    Given the fact that I had only a couple of failures from tests on step
    6, I'm fairly confident about the coverage of this conversion patch.
    If there is a breakage, it's likely to be something in one of the arch
    headers which should be easily discoverable easily on most builds of
    the specific arch.

  • 9dcaa7b25   ALSA: sh: add SuperH DAC audio driver for ALSA V4 ... Browse Code »

    This is a port of the sound/oss/sh_dac_audio.c driver.
    The driver uses an on-chip 8-bit D/A converter, which has a speaker connected
    to one of its channels, found in several ancient HP machines.
    For interrupts it uses a high-resolution timer (hrtimer).
    Tested on SH7709 based hp6xx (HP Jornada 680/690 and HP Palmtop 620lx/660lx).

    Also, since OSS Emulation works, the old OSS sound/oss/sh_dac_audio.c driver
    would be obsolete soon, and it could be removed.

  • 418c8f899   ALSA: Fix section for snd-aica platform driver ... Browse Code »

    Don't use __init but __devinit to define probe function. A pointer to
    snd_aica_probe is passed to the core via platform_driver_register and so the
    function must not disappear after the module is loaded. Using __init
    and having HOTPLUG=y and SND_AICA=m the following probably oopses:

    echo -n AICA > /sys/bus/platform/driver/AICA/unbind
    echo -n AICA > /sys/bus/platform/driver/AICA/bind

    Strange enough add_aicamixer_controls which is only called by
    snd_aica_probe was already using __devinit.

    While at it move the remove function to .devexit.text section.

  • 44e0b6821   [ALSA] protect Dreamcast PCM driver (AICA) from G2 bus effects ... Browse Code »

    The G2 bus on the SEGA Dreamcast connects both the maple peripheral
    bus and the AICA sound memory. DMA requests on one can cause the other
    to timeout on memory operations.
    This patch prevents maple interrupts from causing hiccoughs in the
    AICA sound (maple bus code will land in 2.6.24).
    There are other cleanups for this (AICA) code - but this is in effect
    a regression fix rather than a cleanup.

  • eb695dbf0   sh: Fix Dreamcast DMA issues. ... Browse Code »

    The current SH DMA API is somewhat broken, not correctly matching
    virtual channel to the correct SH DMAC. This wasn't noticeable when
    using g2 DMA for the sound driver - one channel 0 is as good as any
    other! - but caused the pvr2 driver to fail.

    This patch fixes the pvr2 problem and consequently fixes the sound
    driver to ensure it continues to function.
