  • d45b3aaea   ALSA: firewire: Drop superfluous ioctl PCM ops ... Browse Code »

    All the PCM ioctl ops of ALSA FireWire drivers do nothing but calling
    the default handler.

    Now PCM core accepts NULL as the default ioctl ops(*), so let's drop
    altogether.

    (*) commit fc033cbf6fb7 ("ALSA: pcm: Allow NULL ioctl ops")

  • fa84cf094   ALSA: pcm: Nuke snd_pcm_lib_mmap_vmalloc() ... Browse Code »

    snd_pcm_lib_mmap_vmalloc() was supposed to be implemented with
    somewhat special for vmalloc handling, but in the end, this turned to
    just the default handler, i.e. NULL. As the situation has never
    changed over decades, let's rip it off.

  • 6aa7de059   locking/atomics: COCCINELLE/treewide: Convert trivial ACCESS_ONCE() patterns to … ... Browse Code »

    …READ_ONCE()/WRITE_ONCE()

    Please do not apply this to mainline directly, instead please re-run the
    coccinelle script shown below and apply its output.

    For several reasons, it is desirable to use {READ,WRITE}_ONCE() in
    preference to ACCESS_ONCE(), and new code is expected to use one of the
    former. So far, there's been no reason to change most existing uses of
    ACCESS_ONCE(), as these aren't harmful, and changing them results in
    churn.

    However, for some features, the read/write distinction is critical to
    correct operation. To distinguish these cases, separate read/write
    accessors must be used. This patch migrates (most) remaining
    ACCESS_ONCE() instances to {READ,WRITE}_ONCE(), using the following
    coccinelle script:

    ----
    // Convert trivial ACCESS_ONCE() uses to equivalent READ_ONCE() and
    // WRITE_ONCE()

    // $ make coccicheck COCCI=/home/mark/once.cocci SPFLAGS="--include-headers" MODE=patch

    virtual patch

    @ depends on patch @
    expression E1, E2;
    @@

    - ACCESS_ONCE(E1) = E2
    + WRITE_ONCE(E1, E2)

    @ depends on patch @
    expression E;

    - ACCESS_ONCE(E)
    + READ_ONCE(E)

    Add a new helper function snd_pcm_stop_xrun() to the standard sequnce
    lock/snd_pcm_stop(XRUN)/unlock by a single call, and replace the
    existing open codes with this helper.

    The function checks the PCM running state to prevent setting the wrong
    state, too, for more safety.

  • 1b70485f1   ALSA: firewire: extend snd_fw_transaction() ... Browse Code »

    Add a flag to snd_fw_transaction() to allow it to abort when a bus reset
    happens. This removes most of the duplicated error handling loops that
    were required around calls to the low-level fw_run_transaction().

    Also add a flag to suppress error messages; errors are expected when we
    attempt to clean up after the device was unplugged.

  • 94a87157c   firewire: introduce fw_driver.probe and .remove methods ... Browse Code »

    FireWire upper layer drivers are converted from generic
    struct driver.probe() and .remove()
    to bus-specific
    struct fw_driver.probe() and .remove().

    The new .probe() adds a const struct ieee1394_device_id *id argument,
    indicating the entry in the driver's device identifiers table which
    matched the fw_unit to be probed. This new argument is used by the
    snd-firewire-speakers driver to look up device-specific parameters and
    methods. There is at least one other FireWire audio driver currently in
    development in which this will be useful too.

    The new .remove() drops the unused error return code.

    Although all in-tree drivers are being converted to the new methods,
    support for the old methods is left in place in this commit. This
    allows public developer trees to merge this commit and then move to the
    new fw_driver methods.

    Pull IEEE 1394 (FireWire) subsystem updates post v3.3 from Stefan Richter:

    - Some SBP-2 initiator fixes, side product from ongoing work on a target.

    - Reintroduction of an isochronous I/O feature of the older ieee1394 driver
    stack (flush buffer completions); it was evidently rarely used but not
    actually unused. Matching libraw1394 code is already available.

    - Be sure to prefix all kernel log messages with device name or card name,
    and other logging related cleanups.

    - Misc other small cleanups, among them a small API change that affects
    sound/firewire/ too. Clemens Ladisch is aware of it.

  • 210762268   firewire: move fw_device reference counting from drivers to core ... Browse Code »

    fw_unit device drivers invariably need to talk to the fw_unit's parent
    (an fw_device) and grandparent (an fw_card). firewire-core already
    maintains an fw_card reference for the entire lifetime of an fw_device.
    Likewise, let firewire-core maintain an fw_device reference for the
    entire lifetime of an fw_unit so that fw_unit drivers don't have to.

    Since commit 13882a82ee16 (optimize iso queueing by setting
    wake only after the last packet), drivers are required to call
    fw_iso_context_queue_flush() after queueing a batch of packets.
    The missing call would have an effect only if the controller
    queue underruns, but then the DMA would stop completely.
