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.

ALSA: tlv: add DECLARE_TLV_DB_RANGE()

2012-07-16T08:02:18Z

Add a DECLARE_TLV_DB_RANGE() macro so that dB range information can be specified without having to count the items manually for TLV_DB_RANGE_HEAD(). Signed-off-by: Clemens Ladisch Signed-off-by: Takashi Iwai

ALSA: tlv: add DECLARE_TLV_CONTAINER()

2012-07-16T08:02:16Z

Add the DECLARE_TLV_CONTAINER() macro to allow having static TLVs containing more than one item. Signed-off-by: Clemens Ladisch Signed-off-by: Takashi Iwai

ALSA: tlv: compute TLV_*_ITEM lengths automatically

2012-07-16T08:02:10Z

Add helper macros with a little bit of preprocessor magic to automatically compute the length of a TLV item. This lets us avoid having to compute this by hand, and will allow to use items that do not use a fixed length. Signed-off-by: Clemens Ladisch Signed-off-by: Takashi Iwai

ALSA: Add new TLV types for dBwith min/max

2009-06-17T08:56:53Z

Add new types for TLV dB scale specified with min/max values instead of min/step since the resolution can't match always with the one a device provides. For example, usb audio devices give 1/256 dB resolution while ALSA TLV is based on 1/100 dB resolution. The new min/max types have less problems because the possible rounding error happens only at min/max. Signed-off-by: Takashi Iwai

[ALSA] Add definition of TLV dB range compound

2006-09-23T08:46:11Z

Added the definition of TLV dB range compound. It contains one or more dB-range or linear-volume TLV entries with min/max ranges. Used for volume controls with non-linear curves. Signed-off-by: Takashi Iwai Signed-off-by: Jaroslav Kysela

[ALSA] Add the definition of linear volume TLV

2006-09-23T08:44:44Z

Added the definition of linear volume TLV type. Some DSP chips and codecs (e.g. AK codec) use linear volume control. Signed-off-by: Takashi Iwai Signed-off-by: Jaroslav Kysela

[ALSA] Control API - TLV implementation for additional information like dB scale

2006-09-23T08:36:42Z

This patch implements a TLV mechanism to transfer an additional information like dB scale to the user space. The types might be extended in future. Acked-by: Takashi Iwai Signed-off-by: Jaroslav Kysela
