  • 25e9e7565   ASoC: check for substream not channels_min in pcm engines ... Browse Code »

    This is a follow up on 53dea36c70c1857 which fixes the other affected
    pcm engines.

    Description from 53dea36c70c1857:
    Don't rely on the codec's channels_min information to decide wheter or
    not allocate a substream's DMA buffer. Rather check if the substream
    itself was allocated previously.

    Without this patch I was seeing null-pointer dereferenc in atmel-pcm.

  • 85e7652d8   ASoC: Constify snd_soc_dai_ops structs ... Browse Code »

    Commit 1ee46ebd("ASoC: Make the DAI ops constant in the DAI structure")
    introduced the possibility to have constant DAI ops structures, yet this is
    barley used in both existing drivers and also new drivers being submitted,
    although none of them modifies its DAI ops structure. The later is not
    surprising since existing drivers are often used as templates for new drivers.
    So this patch just constifies all existing snd_soc_dai_ops structs to eliminate
    the issue altogether.

    The patch was generated with the following coccinelle semantic patch:
    //
    @@
    identifier ops;
    @@
    -struct snd_soc_dai_ops ops =
    +const struct snd_soc_dai_ops ops =
    { ... };

  • 2c66cb99d   ASoC: Blackfin: push down SPORT settings from global variables ... Browse Code »

    Now that we have multi-component support, take the time to unify the
    SPORT implementations a bit and make the setup dynamic. This kills
    off the global sport_handle which was shared across all the Blackfin
    machine drivers. The pin management aspect is off loaded to platform
    resources, and now multiple SPORTs can be instantiated simultaneously.

  • bfe4ee0a9   ASoC: Blackfin: standardize machine driver names ... Browse Code »

    Some machine drivers were using "bf5xx-", others were using "bf5xx_",
    while others were using "bfin-". Further, some were using the same
    name in the transport layer which makes it hard to use different codecs
    at the same time. So standardize all of them to "bfin-" and make sure
    they are name spaced according to their driver name.

  • 81d7da540   ASoC: Fix codec device id format used by some dai_links ... Browse Code »

    The id part of an I2C device name is created with the "%d-%04x" format string.

    So for example for an I2C device which is connected to the adapter with the id 0
    and has its address set to 0x1a the id part of the devices name would be
    "0-001a".

    Currently some sound board drivers have the id part the codec_name field of
    their dai_link structures set as if it had been created by a "%d-0x%x" format
    string. For example "0-0x1a" instead of "0-001a".

    As a result there is no match between the codec device and the dai_link and no
    sound card is instantiated.

    This patch fixes it.

  • f0fba2ad1   ASoC: multi-component - ASoC Multi-Component Support ... Browse Code »

    This patch extends the ASoC API to allow sound cards to have more than one
    CODEC and more than one platform DMA controller. This is achieved by dividing
    some current ASoC structures that contain both driver data and device data into
    structures that only either contain device data or driver data. i.e.

    struct snd_soc_codec ---> struct snd_soc_codec (device data)
    +-> struct snd_soc_codec_driver (driver data)

    struct snd_soc_platform ---> struct snd_soc_platform (device data)
    +-> struct snd_soc_platform_driver (driver data)

    struct snd_soc_dai ---> struct snd_soc_dai (device data)
    +-> struct snd_soc_dai_driver (driver data)

    struct snd_soc_device ---> deleted

    This now allows ASoC to be more tightly aligned with the Linux driver model and
    also means that every ASoC codec, platform and (platform) DAI is a kernel
    device. ASoC component private data is now stored as device private data.

    The ASoC sound card struct snd_soc_card has also been updated to store lists
    of it's components rather than a pointer to a codec and platform. The PCM
    runtime struct soc_pcm_runtime now has pointers to all its components.

    This patch adds DAPM support for ASoC multi-component and removes struct
    snd_soc_socdev from DAPM core. All DAPM calls are now made on a card, codec
    or runtime PCM level basis rather than using snd_soc_socdev.

    Other notable multi-component changes:-

    * Stream operations now de-reference less structures.
    * close_delayed work() now runs on a DAI basis rather than looping all DAIs
    in a card.
    * PM suspend()/resume() operations can now handle N CODECs and Platforms
    per sound card.
    * Added soc_bind_dai_link() to bind the component devices to the sound card.
    * Added soc_dai_link_probe() and soc_dai_link_remove() to probe and remove
    DAI link components.
    * sysfs entries can now be registered per component per card.
    * snd_soc_new_pcms() functionailty rolled into dai_link_probe().
    * snd_soc_register_codec() now does all the codec list and mutex init.

    This patch changes the probe() and remove() of the CODEC drivers as follows:-

    o Make CODEC driver a platform driver
    o Moved all struct snd_soc_codec list, mutex, etc initialiasation to core.
    o Removed all static codec pointers (drivers now support > 1 codec dev)
    o snd_soc_register_pcms() now done by core.
    o snd_soc_register_dai() folded into snd_soc_register_codec().

  • 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.
