  • The original code doesn't take into consideration that the value of
    MIXART_BA0_SIZE - pos can be less than zero which would lead to a large
    unsigned value for "count".

    Also I moved the check that read size is a multiple of 4 bytes below
    the code that adjusts "count".

  • The commit 6a4f2ccb467e00281470cde2dee08fe5ecde62d1 introduced a wrong
    comparision for the array range check, which effectively skips the whole
    initialization of DAC connections. Fixed now.

  • 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.

    [Note that this is a backported version for 2.6.34.

  • After more tests it appears that EAPD needs to be enabled
    on both the 0x14 and 0x15 NIDs to enable the main speaker
    and headphone amplifiers. The maximum volume setting is
    now equal to what the machine achieves under other operating
    systems.
    Disabling Front or LFE playback triggers EAPD and disables
    the amplifier. As such, these two playback switches have
    been removed from the mixer.

  • With recent (2.6.34) chnages in PCM handling, capture stopped working on my
    OMAP1510 based Amstrad Delta videophone.

    Using 2.6.34-rc2, I was able to correct the problem in 3 different ways:

    1. reverting commit 7b3a177b0d4f92b3431b8dca777313a07533a710,
    2. enabling additional jiffies check with
    echo 4 >/proc/asound/card0/pcm0c0/xrun_debug
    3. applying the patch below.

    Since I wasn't able to reproduce the problem on my i686 PC, I guess the
    problem is probably machine specific.

    The patch reuses the method for software emulation of missing hardware
    pointer, already implemented for playback on OMAP1510. It's possible that
    event if a hardware pointer is available for capture on this machine, its
    behaviour may be not compatible with what upper layer expects.

    If you think the problem may be more general and should be solved differently,
    on a higher level, I can try to work more on it if you give me a hint.

    If the patch gets accepted, I suggest it goes as a fix in the current release
    cycle.

    Created and tested against linux-2.6.34-rc2.

  • …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 commit 4d96eb255c53ab5e39b37fd4d484ea3dc39ab456 broke the interrupt
    time xrun functionality (stream stop etc.) if the CONFIG_SND_PCM_XRUN_DEBUG
    is not set. This is because the xrun() is null defined without it.

    Fix this by letting the function xrun() to be always defined as it was
    before.
