ALSA: fireworks/firewire-lib: add support for recent firmware quirk

2015-08-05T05:52:39+00:00

Fireworks uses TSB43CB43(IceLynx-Micro) as its IEC 61883-1/6 interface. This chip includes ARM7 core, and loads and runs program. The firmware is stored in on-board memory and loaded every powering-on from it. Echo Audio ships several versions of firmwares for each model. These firmwares have each quirk and the quirk changes a sequence of packets. As long as I investigated, AudioFire2/AudioFire4/AudioFirePre8 have a quirk to transfer a first packet with 0x02 in its dbc field. This causes ALSA Fireworks driver to detect discontinuity. In this case, firmware version 5.7.0, 5.7.3 and 5.8.0 are used.

Thus, this quirk may be observed among them. This commit adds a new member for AMDTP structure. This member represents the value of dbc field in a first AMDTP packet. Drivers can set it with a preferred value according to model's quirk. Tested-by: Johannes Oertei Signed-off-by: Takashi Sakamoto Cc: Signed-off-by: Takashi Iwai

This reverts commit 9c6893e0be38b6ca9a56a854226e51dee0a16a5a. The fix is superseded by the next commit as a better implementation for supporting AudioFire2/AudioFire4/AudioFirePre8 quirks. Signed-off-by: Takashi Sakamoto Signed-off-by: Takashi Iwai

ALSA: fireworks: add support for AudioFire2 quirk

2015-07-27T08:12:25+00:00

Fireworks uses TSB43CB43(IceLynx-Micro) as its IEC 61883-1/6 interface. This chip includes ARM7 core, and loads and runs program. The firmware is stored in on-board memory and loaded every powering-on. Echo Audio ships several versions of firmwares for each model. These firmwares have each quirk and the quirk changes a sequence of packets. AudioFire2 has a quirk to transfer a first packet with non-zero in its dbc field. This causes ALSA Fireworks driver to detect discontinuity. As long as I investigated, firmware 5.7, 5.7.6 and 5.8 have this quirk. This commit adds a support for the quirk to handle AudioFire2 packets. For safe, CIP_SKIP_INIT_DBC_CHECK is applied to all versions of AudioFire2's firmwares. 02 00050002 90ffffff <- 42 0005000a 90013000 42 00050012 90014400 42 0005001a 90015800 02 0005001a 90ffffff 42 00050022 90019000 42 0005002a 9001a400 42 00050032 9001b800 02 00050032 90ffffff 42 0005003a 9001d000 42 00050042 9001e400 42 0005004a 9001f800 02 0005004a 90ffffff Signed-off-by: Takashi Sakamoto Signed-off-by: Takashi Iwai

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

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
