  • On DA830/OMAP-L137 and DA850/OMAP-L138 SoCs, the McASP peripheral
    has FIFO support. This FIFO provides additional data buffering. It
    also provides tolerance to variation in host/DMA controller response
    times. More details of the FIFO operation can be found at

    http://focus.ti.com/general/docs/lit/getliterature.tsp?literatureNumber=sprufm1&fileType=pdf

    Existing sequence of steps for audio playback/capture are:
    a. DMA configuration
    b. McASP configuration (configures and enables FIFO)
    c. Start DMA
    d. Start McASP (enables FIFO)

    During McASP configuration, while FIFO was being configured, FIFO
    was being enabled in davinci_hw_common_param() function of
    sound/soc/davinci/davinci-mcasp.c file. This generated a transmit
    DMA event, which gets serviced when DMA is started.

    https://patchwork.kernel.org/patch/84611/ patch clears the DMA
    events before starting DMA, which is the right thing to do. But
    this resulted in a state where DMA was waiting for an event from
    McASP (after step c above), but the event which was already there,
    has got cleared (because of step b above).

    The fix is not to enable the FIFO during McASP configuration as
    FIFO was being enabled as part of McASP start.

  • This fixes a memory corruption when ASoC devices are used in
    full-duplex mode. Specifically for pxa-ssp code, where this pointer
    is dynamically allocated for each direction and destroyed upon each
    stream start.

    All other platforms are fixed blindly, I couldn't even compile-test
    them. Sorry for any breakage I may have caused.

  • …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.

  • The DM365 EVM has two codecs: the Audio Codec (AIC3x) and the Voice Codec,
    the idea is to have both enabled in the same kernel simultaneously. However,
    the current soc-core doesn't support simultaneous codecs, once that
    support will have added, a patch will be posted to enable both codecs in
    the DM365 EVM.

  • The DMA params for McASP with FIFO has been updated so that it works for
    various FIFO levels. A member- 'fifo_level' has been added to the DMA
    params data structure. The fifo_level can be adjusted by the tx[rx]_numevt
    platform data. This is relevant only for DA8xx/OMAP-L1xx platforms. This
    implementation has been tested for numevt values 1, 2, 4, 8.

    - Move queue related mappings to dm.c

    EDMA in DM355 and DM644x has two transfer controllers while DM646x
    has four transfer controllers. Moving the queue to tc mapping and
    queue priority mapping to dm.c will be helpful to probe these
    mappings from platform device so that the machine_is_* testing will
    be avoided.

    - add channel mapping logic

    Channel mapping logic is introduced in dm646x EDMA. This implies
    that there is no fixed association for a channel number to a
    parameter entry number. In other words, using the DMA channel
    mapping registers (DCHMAPn), a PaRAM entry can be mapped to any
    channel. While in the case of dm644x and dm355 there is a fixed
    mapping between the EDMA channel and Param entry number.

    support. This FIFO provides additional data buffering. It also provides
    tolerance to variation in host/DMA controller response times.
    The read and write FIFO sizes are 256 bytes each. If FIFO is enabled,
    the DMA events from McASP are sent to the FIFO which in turn sends DMA requests
    to the host CPU according to the thresholds programmed.
    More details of the FIFO operation can be found at
    http://focus.ti.com/general/docs/lit/getliterature.tsp?literatureNumber=
    sprufm1&fileType=pdf

    This patch adds support for FIFO configuration. The platform data has a
