  • 7d2aae1e8   [PATCH] ALSA: Fix sysfs breakage ... Browse Code »

    The recent change for a new sysfs tree with card* object breaks the
    /sys/class/sound tree if CONFIG_SYSFS_DEPRECATED is enabled.
    The device in each entry doesn't point the correct device object:

    /sys/class/sound
    ...
    |-- pcmC0D0c
    | |-- dev
    | |-- device -> ../../../class/sound/card0
    | |-- pcm_class
    | |-- power
    | | `-- wakeup
    | |-- subsystem -> ../../../class/sound
    | `-- uevent

    Also, this change breaks some drivers (like sound/arm/*) referring
    card->dev directly to obtain the device object for memory handling.

    This patch reverts the semantics of card->dev to the former version,
    which points to a real device object. The card* object is stored in a
    new card->card_dev field, instead. The device parent is chosen either
    card->dev or card->card_dev according to CONFIG_SYSFS_DEPRECATED to
    keep the tree compatibility.
    Also, card* isn't created if CONFIG_SYSFS_DEPRECATED is enabled. The
    reason of card* object is a root of all beloing devices, and it makes
    little sense if each sound device points to the real device object
    directly.

  • d80f19fab   Driver core: convert sound core to use struct device ... Browse Code »

    Converts from using struct "class_device" to "struct device" making
    everything show up properly in /sys/devices/ with symlinks from the
    /sys/class directory.

    It also makes the struct sound_card to show up as a "real" device
    where all the different sound class devices are placed as childs
    and different card attribute files can hang off of. /sys/class/sound is
    still a flat directory, but the symlink targets of all devices belonging
    to the same card, point the the /sys/devices tree below the new card
    device object.

    Thanks to Kay for the updates to this patch.

  • a9edfc602   [ALSA] Handle file operations during snd_card disconnects using static file->f_op ... Browse Code »

    Alsa used to kmalloc one file->f_op per file per disconnecting snd_card.
    This led to oopses sometimes when file->f_op was freed before __fput()
    finished.
    Patch adds a virtual device for disconnect: VDD.
    VDD consists of:
    LIST_HEAD(shutdown_files)
    protected by DEFINE_SPINLOCK(shutdown_mutex)
    static struct file_operations snd_shutdown_f_ops
    and functions assigned to it
    Additions to struct snd_monitor_file
    to specify if instance is hidden by VDD or not.
    A VDD's instance is
    created in snd_card_disconnect() under the card->files_lock.
    cleaned up in snd_card_file_remove() under the card->files_lock.

    Mark the f_ops members of inodes as const, as well as fix the
    ripple-through this causes by places that copy this f_ops and then "do
    stuff" with it.

  • dd0fc66fb   [PATCH] gfp flags annotations - part 1 ... Browse Code »

    - added typedef unsigned int __nocast gfp_t;

    - replaced __nocast uses for gfp flags with gfp_t - it gives exactly
    the same warnings as far as sparse is concerned, doesn't change
    generated code (from gcc point of view we replaced unsigned int with
    typedef) and documents what's going on far better.

  • ecbcfe36f   [ALSA] Introduce snd_card_set_generic_dev() ... Browse Code »

    ALSA Core
    A new function snd_card_set_generic_dev() is introduced to add the
    'generic device' support for devices without proper bus on sysfs.
    It's a last resort, and should be removed in future when they have
    a proper bus, instead.

  • d5750f678   [ALSA] cleanup and typo-correction ... Browse Code »

    ALSA Core
    This patch changes, adds and remove some comments, which will
    make now more sense and fit on a 80-char line. It also changes
    the order of snd_power_wait() to make the file more readable.
    It removes the device.c comment in front of _snd_minor,
    cause snd_minor has nothing to do with device.c.
    The both typos in the kernel-docs were corrected too.

  • 543537bd9   [PATCH] create a kstrdup library function ... Browse Code »

    This patch creates a new kstrdup library function and changes the "local"
    implementations in several places to use this function.

    Most of the changes come from the sound and net subsystems. The sound part
    had already been acknowledged by Takashi Iwai and the net part by David S.
    Miller.

    I left UML alone for now because I would need more time to read the code
    carefully before making changes there.

  • 1da177e4c   Linux-2.6.12-rc2 ... Browse Code »

    Initial git repository build. I'm not bothering with the full history,
    even though we have it. We can create a separate "historical" git
    archive of that later if we want to, and in the meantime it's about
    3.2GB when imported into git - space that would just make the early
    git days unnecessarily complicated, when we don't have a lot of good
    infrastructure for it.

    Let it rip!
