    We used to pass NULL to memory allocators for ISA devices due to
    historical reasons. But we prefer rather a proper device object to be
    assigned, so let's fix it by replacing snd_dma_isa_data() call with
    card->dev reference, and kill snd_dma_isa_data() definition.

  • e992ef570   Annotate hardware config module parameters in sound/isa/ ... Browse Code »

    When the kernel is running in secure boot mode, we lock down the kernel to
    prevent userspace from modifying the running kernel image. Whilst this
    includes prohibiting access to things like /dev/mem, it must also prevent
    access by means of configuring driver modules in such a way as to cause a
    device to access or modify the kernel image.

    To this end, annotate module_param* statements that refer to hardware
    configuration and indicate for future reference what type of parameter they
    specify. The parameter parser in the core sees this information and can
    skip such parameters with an error message if the kernel is locked down.
    The module initialisation then runs as normal, but just sees whatever the
    default values for those parameters is.

    Note that we do still need to do the module initialisation because some
    drivers have viable defaults set in case parameters aren't specified and
    some drivers support automatic configuration (e.g. PNP or PCI) in addition
    to manually coded parameters.

    This patch annotates drivers in sound/isa/.

    snd_es18xx_pcm() takes a pointer to a pointer of a PCM where if this
    parameter is provided the newly allocated PCM is stored. All callers pass
    NULL though, so remove the parameter. This makes the code a bit cleaner and
    shorter.

    module_param(bool) used to counter-intuitively take an int. In
    fddd5201 (mid-2009) we allowed bool or int/unsigned int using a messy

    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.

    Since commit [e58aa3d2: genirq: Run irq handlers with interrupts disabled],
    We run all interrupt handlers with interrupts disabled
    and we even check and yell when an interrupt handler
    returns with interrupts enabled (see commit [b738a50a:
    genirq: Warn when handler enables interrupts]).

    So now this flag is a NOOP and can be removed.

  • dba8b4699   ALSA: mpu401: clean up interrupt specification ... Browse Code »

    The semantics of snd_mpu401_uart_new()'s interrupt parameters are
    somewhat counterintuitive: To prevent the function from allocating its
    own interrupt, either the irq number must be invalid, or the irq_flags
    parameter must be zero. At the same time, the irq parameter being
    invalid specifies that the mpu401 code has to work without an interrupt
    allocated by the caller. This implies that, if there is an interrupt
    and it is allocated by the caller, the irq parameter must be set to
    a valid-looking number which then isn't actually used.

    With the removal of IRQF_DISABLED, zero becomes a valid irq_flags value,
    which forces us to handle the parameters differently.

    This patch introduces a new flag MPU401_INFO_IRQ_HOOK for when the
    device interrupt is handled by the caller, and makes the allocation of
    the interrupt to depend only on the irq parameter. As suggested by
    Takashi, the irq_flags parameter was dropped because, when used, it had
    the constant value IRQF_DISABLED.

  • 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.

    1. Set the third argument of the snd_device_new to not NULL, so there is
    no warning about bug during chip detection. The third argument is not
    used in this driver. It was changed in my previous patch.

    2. Remove the fm_port and mpu_port fields from the snd_es18xx structure.
    They can be converted to function arguments.

    3. Remove the dmaN_size fields from the snd_es18xx structure. These
    values are used only in pointer functions and can be easily calculated.

    4. Remove the ctrl_lock spinlock which is used only in one read function
    which is called once during chip initialization. There are many
    writes to the same register and they are not protected on purpose
    (see the comment ina the snd_es18xx_config_write()).

    5. Use the first part of the text5Sources string table as the text4Soruces
    table (they are the same).

    6. Merge the same cases for the ES1887 and ES1888 when setting chip's caps.

    7. Move the snd_es18xx_reset() to __devinit section.
