  • 4434ade8c   ALSA: usb-audio: add support for Akai MPD16 ... Browse Code »

    The decoding/encoding is based on own reverse-engineering. Both control and
    data ports are handled. Writing to control port supports SysEx events only,
    as this is the only type of messages that MPD16 recognizes.

  • 997ea58eb   USB: rename usb_buffer_alloc() and usb_buffer_free() users ... Browse Code »

    For more clearance what the functions actually do,

    usb_buffer_alloc() is renamed to usb_alloc_coherent()
    usb_buffer_free() is renamed to usb_free_coherent()

    They should only be used in code which really needs DMA coherency.

    All call sites have been changed accordingly, except for staging
    drivers.

  • e213e9cf7   ALSA: sound/usb: add preliminary support for UAC2 interrupts ... Browse Code »

    For both UAC1 and UAC2, interrupt endpoint messages are now parsed with
    structs rather that with anonymous buffer array accesses.

    For UAC2, only CUR interrupt notifications are supported for now.

    snd_usb_mixer_status_complete() was renamed to
    snd_usb_mixer_interrupt().

    Fixed one indentation flaw on the way.

  • 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.

  • fca5bca48   ALSA: usbaudio: Add basic support for M-Audio Fast Track Ultra series ... Browse Code »

    This adds basic support for M-Audio's Fast Track Ultra series of USB
    audio interfaces. It is a refactored version of the patch Clemens
    Ladisch posted some time ago. Neither playback nor capturing work
    properly at 44100 Hz (don't know why).
    The other sampling rates work properly. There's no support for the DSP
    mixer, yet.
