ALSA: bebob: add support for Behringer FCA 610/1616

2015-06-15T11:38:47+00:00

They're based on DM1500 (ArchWave produced), and BeBoB version 3 is installed. $ cat /proc/asound/FCA610/firewire/firmware Manufacturer: bridgeCo Protocol Ver: 3 Build Ver: 0 GUID: 0x001564000002AD73 Model ID: 0x03 Model Rev: 0 Firmware Date: 20121102 Firmware Time: 153431 Firmware ID: 0x610 Firmware Ver: 8348 Base Addr: 0x400C0080 Max Size: 1422624 Loader Date: 20121015 Loader Time: 104710 Signed-off-by: Takashi Sakamoto Signed-off-by: Takashi Iwai

ALSA: bebob: keep duplex streams always to keep internal multiplexer properly

2015-06-15T11:38:29+00:00

Behringer FCA610 transmits packets with periodic noisy PCM samples when receiving no streams, and generates a bit noisy sound. ALSA BeBoB driver is programmed to establish both in/out connections when starting streaming, then transfers packets as userspace applications requested. This means that there's a case that one of incoming/outgoing streams is running, to save CPU and bandwidth usage. Although, it's natural to start transferring packets in both direction. This commit makes this driver to keeps duplex streams always. Tested-by: Kim Tore Jensen Signed-off-by: Takashi Sakamoto Signed-off-by: Takashi Iwai

ALSA: bebob: loosen up severity of checking continuity for BeBoB v3 quirk

2015-06-15T11:38:14+00:00

PrismSound Orpheus, Behringer UFX1604 and FCA610 work with BeBoB v3, and they're confirmed to transmit discontinuous packets in the beginning of streaming. payload CIP headers 8 0x00070000 0x9002FFFF 8 0x00070000 0x9002FFFF 8 0x00070000 0x9002FFFF 8 0x00070008 0x9002FFFF <- 8 0x00070008 0x9002FFFF 8 0x00070008 0x9002FFFF 8 0x00070008 0x9002FFFF 8 0x00070008 0x9002FFFF 8 0x00070008 0x9002FFFF 232 0x00070000 0x9002E798 <- 232 0x00070008 0x9002FB99 232 0x00070010 0x90021398 8 0x00070018 0x9002FFFF (This sample was got with Behringer FCA610 and FFADO library.)

ALSA: bebob: expand timeout for DM1500 quirk

2015-06-15T11:38:00+00:00

Behringer FCA610 and UFX1604 is confirmed to require more time till transmitting packets after establishing connections. This seems to be a quirk of DM1500 ASIC which ArchWave produced. For this quirk, this commit extends the time to wait up to 2 seconds. As a result, in worst cases, below userspace functions require 2 seconds to return. - snd_pcm_prepare() - snd_pcm_hw_params() - snd_pcm_recover() Tested-by: Kim Tore Jensen Signed-off-by: Takashi Sakamoto Signed-off-by: Takashi Iwai

ALSA: bebob: add 'version' member for BeBoB protocol version

2015-06-15T11:37:26+00:00

BeBoB installed devices have BeBoB register area. This area stores basic information about its firmware. A register has its protocol version. This commit adds 'version' member and store the device's protocol version to handle v3 quirks in following commits.

ALSA: bebob: add SYT-Match support

2015-06-15T11:37:07+00:00

In previous commits, this driver can detect the source of clock as mush as possible. SYT-Match mode is also available. This commit purge the restriction. Signed-off-by: Takashi Sakamoto Signed-off-by: Takashi Iwai

ALSA: bebob: obsolete string literal expression for clock source

2015-06-15T11:36:44+00:00

The old string literals were completely replaced by new normalized representation. This commit obsoletes it. Signed-off-by: Takashi Sakamoto Signed-off-by: Takashi Iwai

ALSA: bebob: use normalized representation for the type of clock source

2015-06-15T11:36:00+00:00

This commit changes function prototype and its processing. As a result, function caller can execute additional processing according to detected clock source. Signed-off-by: Takashi Sakamoto Signed-off-by: Takashi Iwai

ALSA: bebob: preparation for replacing string literals by normalized representation for model-dependent structures

2015-06-15T11:34:47+00:00

Previous commit adds a enumerator as a normalized representation of clock source, while model-dependent structures still use string literals for this purpose. This commit is a preparation for replacement. Signed-off-by: Takashi Sakamoto Signed-off-by: Takashi Iwai

ALSA: bebob: apply new enumerator to normalize the type of clock source

2015-06-15T11:34:29+00:00

Previous commit allows this driver to detect several types of clock source, while there's no normalized expression for it. This commit adds a new enumerator for this purpose. Signed-off-by: Takashi Sakamoto Signed-off-by: Takashi Iwai
