2006-12-01Driver core: convert sound core to use struct deviceGreg Kroah-Hartman
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. Signed-off-by: Kay Sievers <kay.sievers@novell.com> Acked-by: Jaroslav Kysela <perex@suse.cz> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
2006-10-06[ALSA] Handle file operations during snd_card disconnects using static ↵Karsten Wiese
file->f_op 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.

2006-09-23[ALSA] Add pcm_class attribute to PCM sysfs entryTakashi Iwai
This patch adds a new attribute, pcm_class, to each PCM sysfs entry. It's useful to detect what kind of PCM stream is, for example, HAL can check whether it's a modem or not. Signed-off-by: Takashi Iwai <tiwai@suse.de> Signed-off-by: Jaroslav Kysela <perex@suse.cz>

2006-09-23[ALSA] Unregister device files at disconnectionTakashi Iwai
Orignally proposed by Sam Revitch <sam.revitch@gmail.com>. Unregister device files at disconnection to avoid the futher accesses. Also, the dev_unregister callback is removed and replaced with the combination of disconnect + free. A new function snd_card_free_when_closed() is introduced, which is used in USB disconnect callback. Signed-off-by: Takashi Iwai <tiwai@suse.de> Signed-off-by: Jaroslav Kysela <perex@suse.cz>

2006-01-03[ALSA] dynamic minors (3/6): store device-specific object pointers dynamicallyClemens Ladisch
Instead of storing the pointers to the device-specific structures in an array, put them into the struct snd_minor, and look them up dynamically. This makes the device type modules independent of the minor number encoding. Signed-off-by: Clemens Ladisch <clemens@ladisch.de>
2006-01-03[ALSA] dynamic minors (2/6): simplify storage of snd_minor structuresClemens Ladisch
Modules: ALSA Core Store the snd_minor structure pointers in one array instead of using a separate list for each card. This simplifies the mapping from device files to minor struct by removing the need to know about the encoding of the card number in the minor number. Signed-off-by: Clemens Ladisch <clemens@ladisch.de>
2006-01-03[ALSA] dynamic minors (1/6): store device type in struct snd_minorClemens Ladisch
Instead of a comment string, store the device type in the snd_minor structure. This makes snd_minor more flexible, and has the nice side effect that we don't need anymore to create a separate snd_minor template for registering a device but can pass the file_operations directly to snd_register_device().

2006-01-03[ALSA] Decentralize PM controlTakashi Iwai

2005-11-04[ALSA] Remove snd_runtime_check() macroTakashi Iwai

2005-10-08[PATCH] gfp flags annotations - part 1Al Viro
- 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.

2005-07-28[ALSA] cleanup and typo-correctionHenrik Kretzschmar
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.

2005-06-23[PATCH] create a kstrdup library functionPaulo Marques
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.

2005-04-16Linux-2.6.12-rc2Linus Torvalds
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!
