From 6c5e1ac0e144a8560cfa11bed8cdadab9491952f Mon Sep 17 00:00:00 2001 From: Takashi Sakamoto Date: Mon, 18 Jun 2018 21:07:55 +0900 Subject: ALSA: firewire-motu: add support for Motu Traveler This commit adds support for MOTU Traveler, launched in 2005, discontinued quite before. As a result, transmission of PCM frame and MIDI messages is available via ALSA PCM and RawMIDI/Sequencer interfaces. This model supports sampling transmission frequency up to 192.0 kHz, and AES/EBU on XLR interface and ADAT on optical interface. Unlike Motu 828MkII, Windows driver can switch fetching mode for DSP, like mute/unmute feature. Although this commit enables high sampling transmission frequency, actual sound from this model is not good. As long as I tested, it's silence at 176.4 kHz, and it includes hissing noise at 192.0 kHz. In my opinion, as I reported at 3526ce7f9ba7 ('ALSA: firewire-motu: add MOTU specific protocol layer'), timestamping on source packet header (SPH) may not still be good for this model as well. $ python2 crpp < /sys/bus/firewire/devices/fw1/config_rom ROM header and bus information block ----------------------------------------------------------------- 400 04106505 bus_info_length 4, crc_length 16, crc 25861 404 31333934 bus_name "1394" 408 20001000 irmc 0, cmc 0, isc 1, bmc 0, cyc_clk_acc 0, max_rec 1 (4) 40c 0001f200 company_id 0001f2 | 410 0001f32f device_id 000001f32f | EUI-64 0001f2000001f32f root directory ----------------------------------------------------------------- 414 0004c65c directory_length 4, crc 50780 418 030001f2 vendor 41c 0c0083c0 node capabilities per IEEE 1394 420 8d000006 --> eui-64 leaf at 438 424 d1000001 --> unit directory at 428 unit directory at 428 ----------------------------------------------------------------- 428 00035955 directory_length 3, crc 22869 42c 120001f2 specifier id 430 13000009 version 434 17107800 model eui-64 leaf at 438 ----------------------------------------------------------------- 438 000206b2 leaf_length 2, crc 1714 43c 0001f200 company_id 0001f2 | 440 0001f32f device_id 000001f32f | EUI-64 0001f2000001f32f Signed-off-by: Takashi Sakamoto Signed-off-by: Takashi Iwai --- sound/firewire/motu/motu.c | 16 ++++++++++++++++ 1 file changed, 16 insertions(+) (limited to 'sound/firewire/motu/motu.c') diff --git a/sound/firewire/motu/motu.c b/sound/firewire/motu/motu.c index 445aa589582d..300d31b6f191 100644 --- a/sound/firewire/motu/motu.c +++ b/sound/firewire/motu/motu.c @@ -209,6 +209,21 @@ static const struct snd_motu_spec motu_828mk2 = { .analog_out_ports = 8, }; +const struct snd_motu_spec snd_motu_spec_traveler = { + .name = "Traveler", + .protocol = &snd_motu_protocol_v2, + .flags = SND_MOTU_SPEC_SUPPORT_CLOCK_X2 | + SND_MOTU_SPEC_SUPPORT_CLOCK_X4 | + SND_MOTU_SPEC_TX_RETURN_CHUNK | + SND_MOTU_SPEC_HAS_AESEBU_IFACE | + SND_MOTU_SPEC_HAS_OPT_IFACE_A | + SND_MOTU_SPEC_RX_MIDI_2ND_Q | + SND_MOTU_SPEC_TX_MIDI_2ND_Q, + + .analog_in_ports = 8, + .analog_out_ports = 8, +}; + static const struct snd_motu_spec motu_828mk3 = { .name = "828mk3", .protocol = &snd_motu_protocol_v3, @@ -253,6 +268,7 @@ static const struct snd_motu_spec motu_audio_express = { static const struct ieee1394_device_id motu_id_table[] = { SND_MOTU_DEV_ENTRY(0x101800, &motu_828mk2), + SND_MOTU_DEV_ENTRY(0x107800, &snd_motu_spec_traveler), SND_MOTU_DEV_ENTRY(0x106800, &motu_828mk3), /* FireWire only. */ SND_MOTU_DEV_ENTRY(0x100800, &motu_828mk3), /* Hybrid. */ SND_MOTU_DEV_ENTRY(0x104800, &motu_audio_express), -- cgit v1.2.3
