ALSA: oxfw: Add hwdep interface

2014-12-10T09:50:00Z

This interface is designed for mixer/control application. By using this interface, an application can get information about firewire node, can lock/unlock kernel streaming and can get notification at starting/stopping kernel streaming.

Merge branch 'for-linus' into for-next

2014-11-28T17:30:19Z

The commit [7a2e9ddc: ALSA: usb-audio: Add native DSD support for Denon/Marantz DACs] requires the new format definition that has landed only in for-next branch.

ALSA: pcm: Add big-endian DSD sample formats and fix XMOS DSD sample format

2014-11-21T14:13:28Z

This patch fixes XMOS DSD sample format to DSD_U32_BE and also adds DSD_U16_BE and DSD_U32_BE sample formats. Signed-off-by: Jussi Laako Acked-by: Jurgen Kramer Signed-off-by: Takashi Iwai

ALSA: Fix invalid kerneldoc markers

2014-11-11T08:39:17Z

They are no real kerneldoc comments, so drop such markers. Signed-off-by: Takashi Iwai

ALSA: doc: Fix uapi/sound/compress_offload.h kerneldoc comments

2014-10-29T07:22:05Z

so that make htmldocs works properly. Since kerneldoc can't handle noname enum properly, name enum sndrv_compress_encoder. Signed-off-by: Takashi Iwai

ALSA: pcm: add new DSD sampleformat for native DSD playback on XMOS based devices

2014-09-08T15:11:00Z

XMOS based USB DACs with native DSD support expose this feature via a USB alternate setting. The audio format is either 32-bit raw or a 32-bit PCM format. To utilize this feature on linux this patch introduces a new 32-bit DSD sampleformat DSD_U32_LE. A follow up patch will add a quirk for XMOS based devices to utilize the new format. Further patches will add support to alsa-lib. Signed-off-by: Jurgen Kramer Signed-off-by: Takashi Iwai

ALSA: pcm: Introduce protocol version field to sw_params

2014-07-21T07:07:46Z

For controlling the new fields more strictly, add sw_params.proto field indicating the protocol version of the user-space. User-space should fill the SNDRV_PCM_VERSION value it's built with, then kernel can know whether the new fields should be evaluated or not. And now tstamp_type field is evaluated only when the valid value is set there. This avoids the wrong override of tstamp_type to zero, which is SNDRV_PCM_TSTAMP_TYPE_GETTIMEOFDAY.

ALSA: pcm: Add timestamp type to sw_params

2014-07-10T14:58:15Z

For allowing adjusting the timestamp type on the fly, add it to sw_params. The existing ioctl is still kept for compatibility. Along with this, increment the PCM protocol version. The extension was suggested by Clemens Ladisch. Acked-by: Jaroslav Kysela Reviewed-by: Mark Brown Signed-off-by: Takashi Iwai

ALSA: Provide a CLOCK_MONOTONIC_RAW timestamp type

2014-07-10T14:58:13Z

For applications which need to synchronise with external timebases such as broadcast TV applications the kernel monotonic time is not optimal as it includes adjustments from NTP and so may still include discontinuities due to that. A raw monotonic time which does not include any adjustments is available in the kernel from getrawmonotonic() so provide userspace with a new timestamp type SNDRV_PCM_TSTAMP_TYPE_MONOTONIC_RAW which provides timestamps based on this as an option.

ALSA: compress: fix the struct alignment to 4 bytes

2014-06-23T10:15:33Z

In 64bit systems the compiler can default align to 8bytes causing mis-match with 32bit usermode. Avoid this is future by ensuring all the structures shared with usermode are packed and aligned to 4 bytes irrespective of arch used [coding style fixes by tiwai] Signed-off-by: Vinod Koul Signed-off-by: Takashi Iwai
