ALSA: Avoid endless sleep after disconnect

2012-10-30T10:07:15Z

When disconnect callback is called, each component should wake up sleepers and check card->shutdown flag for avoiding the endless sleep blocking the proper resource release. Cc: Signed-off-by: Takashi Iwai

ALSA: PCM: Fix some races at disconnection

2012-10-30T10:06:48Z

Fix races at PCM disconnection: - while a PCM device is being opened or closed - while the PCM state is being changed without lock in prepare, hw_params, hw_free ops Reported-by: Matthieu CASTET Cc: Signed-off-by: Takashi Iwai

ALSA: PCM: channel mapping API implementation

2012-09-06T16:01:16Z

This patch implements the basic data types for the standard channel mapping API handling. - The definitions of the channel positions and the new TLV types are added in sound/asound.h and sound/tlv.h, so that they can be referred from user-space. - Introduced a new helper function snd_pcm_add_chmap_ctls() to create control elements representing the channel maps for each PCM (sub)stream. - Some standard pre-defined channel maps are provided for convenience.

Pull avoidance patches from Paul Gortmaker: "Nearly every subsystem has some kind of header with a proto like: void foo(struct device *dev); and yet there is no reason for most of these guys to care about the sub fields within the device struct. This allows us to significantly reduce the scope of headers including headers. For this instance, a reduction of about 40% is achieved by replacing the include with the simple fact that the device is some kind of a struct. Unlike the much larger module.h cleanup, this one is simply two commits. One to fix the implicit users, and then one to delete the device.h includes from the linux/include/ dir wherever possible." * tag 'device-for-3.4' of git://git.kernel.org/pub/scm/linux/kernel/git/paulg/linux: device.h: audit and cleanup users in main include dir device.h: cleanup users outside of linux/include (C files)

device.h: cleanup users outside of linux/include (C files)

2012-03-11T18:27:37Z

For files that are actively using linux/device.h, make sure that they call it out. This will allow us to clean up some of the implicit uses of linux/device.h within include/* without introducing build regressions. Yes, this was created by "cheating" -- i.e. the headers were cleaned up, and then the fallout was found and fixed, and then the two commits were reordered. This ensures we don't introduce build regressions into the git history. Signed-off-by: Paul Gortmaker

ALSA: PCM - Add PCM creation API for internal PCMs.

2012-02-09T08:20:22Z

The new ASoC dynamic PCM core needs to create PCMs and substreams that are for use by internal ASoC drivers only and not visible to userspace for direct IO. These new PCMs are similar to regular PCMs expect they have no device nodes or procfs entries. The ASoC component drivers use them in exactly the same way as regular PCMs for PCM and DAI operations. The intention is that a dynamic PCM based driver will register both regular PCMs and internal PCMs. The regular PCMs will be used for all IO with userspace however the internal PCMs will be used by the driver to route digital audio through numerous back end DAI links (with potentially a DSP providing different hw_params, DAI formats based on the regular front end PCM params) to devices like CODECs, MODEMs, Bluetooth, FM, DMICs, etc This patch adds a new snd_pcm_new_internal() API call to create the internal PCM without device nodes or procfs. It also adds adds a new internal flag to snd_pcm. [fixed minor coding-style issues by tiwai] Signed-off-by: Liam Girdwood Signed-off-by: Takashi Iwai

sound: Add module.h to the previously silent sound users

2011-10-31T23:31:21Z

Lots of sound drivers were getting module.h via the implicit presence of it in but we are going to clean that up. So fix up those users now. Signed-off-by: Paul Gortmaker

ALSA: core: sparse cleanups

2011-02-14T16:10:11Z

Change the core code where sparse complains. In most cases, this means just adding annotations to confirm that we indeed want to do the dirty things we're doing. Signed-off-by: Clemens Ladisch Signed-off-by: Takashi Iwai

ALSA: pcm - Fix race with proc files

2010-09-16T21:06:50Z

The PCM proc files may open a race against substream close, which can end up with an Oops. Use the open_mutex to protect for it. Signed-off-by: Takashi Iwai
