  • 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.

  • 934c2b6d0   ALSA: use KBUILD_MODNAME for request_irq argument in sound/pci/* ... Browse Code »

    The name argument of request_irq() appears in /proc/interrupts, and
    it's quite ugly when the name entry contains a space or special letters.
    In general, it's simpler and more readable when the module name appears
    there, so let's replace all entries with KBUILD_MODNAME.

  • 3733e424c   ALSA: Use KBUILD_MODNAME for pci_driver.name entries ... Browse Code »

    The convention for pci_driver.name entry in kernel drivers seem to be
    the module name or equivalent ones. But, so far, almost all PCI sound
    drivers use more verbose name like "ABC Xyz (12)", and these are fairly
    confusing when appearing as a file name.

    This patch converts the all pci_driver.name entries in sound/pci/* to
    use KBUILD_MODNAME for more unified appearance.

  • 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.

    This patch fixes a division by zero error in the irq handler.

    There is a small window between the hw_params() callback and when
    runtime->frame_bits is set by ALSA middle layer. When another substream is
    already running, if an interrupt is delivered during that window the irq
    handler calls pcm_pointer() which does a division by zero. The patch below
    makes the irq handler skip substreams that are initialized but not started
    yet. Cc to Clemens Ladisch because he proposed an alternate fix.

    This patch adds suspend and resume callbacks.
    It also rearranges parts of the initialization code so it can be
    used in both the first initialization (when the module is loaded we
    also have to load default settings) and the resume callback (where
    we have to restore the previous settings).

    Move the controls init code outside the init_hw() function because is must
    not be called during resume.

    This patch moves the code that initializes the card's controls with
    default valued from the init_hw() function into a separated
    set_mixer_defaults() function (one for each of the 16 supported
    cards). This change is necessary because during resume we must
    resurrect the hardware without losing the previous
    settings. set_mixer_defaults() must be called only once when the
    module is loaded.

  • 4f8ada444   ALSA: Echoaudio - Add firmware cache #2 ... Browse Code »

    This patch implements a simple cache for the firmware files when CONFIG_PM is defined.

    This patch changes get_firmware(), free_firmware() and adds
    free_firmware_cache(). The first two functions implement a very
    simple cache and the latter is used to actually release all the stored
    firmwares when the module is unloaded.
    When CONFIG_PM is not enabled those functions act as before, that is
    free_firmware() releases the firmware immediately and
    free_firmware_cache() does nothing.

    Changes the way the firmware is passed through functions.

    When CONFIG_PM is enabled the firmware cannot be released because the
    driver will need it again to resume the card.
    With this patch the firmware is passed as an index of the struct
    firmware card_fw[] in place of a pointer. That same index is then used
    to locate the firmware in the firmware cache.

    There is a long standing bug in the drivers for cards with a vmixer because
    I overlooked a detail in the c++ generic driver by echoaudio. Those cards
    do not have a line-out volume control. It is a virtual control provided by
    the generic driver. The bug is harmless because the DSP just ignores the
    command to change the volume.
    *NB:* It breaks alsa-tools/echomixer. A patch for it will follow.

    This patch removes the line-out volume control from vmixer-equipped cards.
