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: 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

ALSA: compress: Cancel the optimization of compiler and fix the size of struct for all platform.

2014-06-12T09:55:41Z

Cancel the optimization of compiler for struct snd_compr_avail which size will be 0x1c in 32bit kernel while 0x20 in 64bit kernel under the optimizer. That will make compaction between 32bit and 64bit. So add packed to fix the size of struct snd_compr_avail to 0x1c for all platform.

ALSA: bebob: Add hwdep interface

2014-05-26T12:31:03Z

This interface is designed for mixer/control application. By using hwdep interface, the application can get information about firewire node, can lock/unlock kernel streaming and can get notification at starting/stopping kernel streaming. Signed-off-by: Takashi Sakamoto Signed-off-by: Takashi Iwai

ALSA: fireworks: Add command/response functionality into hwdep interface

2014-05-26T12:28:58Z

This commit adds two functionality for hwdep interface, adds two parameters for this driver, add a node for proc interface. To receive responses from devices, this driver already allocate own callback into initial memory space in host controller. This means no one can allocate its own callback to the address. So this driver must give a way for user applications to receive responses. This commit adds a functionality to receive responses via hwdep interface. The application can receive responses to read from this interface. To achieve this, this commit adds a buffer to queue responses. The default size of this buffer is 1024 bytes. This size can be changed to give preferrable size to 'resp_buf_size' parameter for this driver. The application should notice rest of space in this buffer because this driver don't push responses when this buffer has no space. Additionaly, this commit adds a functionality to transmit commands via hwdep interface. The application can transmit commands to write into this interface. I note that the application can transmit one command at once, but can receive as many responses as possible untill the user-buffer is full. When using these interfaces, the application must keep maximum number of sequence number in command within the number in firewire.h because this driver uses this number to distinguish the response is against the command by the application or this driver. Usually responses against commands which the application transmits are pushed into this buffer. But to enable 'resp_buf_debug' parameter for this driver, all responses are pushed into the buffer. When using this mode, I reccomend to expand the size of buffer. Finally this commit adds a new node into proc interface to output status of the buffer.
