2017-04-05ALSA: oxfw: fix regression to handle Stanton SCS.1m/1dTakashi Sakamoto
At a commit 6c29230e2a5f ("ALSA: oxfw: delayed registration of sound card"), ALSA oxfw driver fails to handle SCS.1m/1d, due to -EBUSY at a call of snd_card_register(). The cause is that the driver manages to register two rawmidi instances with the same device number 0. This is a regression introduced since kernel 4.7. This commit fixes the regression, by fixing up device property after discovering stream formats.

2017-01-03ALSA: oxfw: add support for Mackie Onyx 1640iTakashi Sakamoto
As of kernel 4.10, ALSA OXFW driver has no entry for Onyx 1640i produced by Mackie (Loud Technologies). This commit supplement it. I note that there're two models produced by Mackie (Loud Technologies), which have the same name 'Onyx 1640i'. The former model based on OXFW970, the latter model based on Dice. This is probably due to low quality of communication of OXFW series. Additionally, the tester reports his or her experiences to get unexpected result at higher sampling transmission frequency as 88.2/96.0 kHz. We didn't have further investigation yet[0]. $ ./linux-firewire-utils/src/crpp < config_rom ROM header and bus information block ----------------------------------------------------------------- 400 042525ce bus_info_length 4, crc_length 37, crc 9678 404 31333934 bus_name "1394" 408 20ff5003 irmc 0, cmc 0, isc 1, bmc 0, cyc_clk_acc 255, max_rec 5 (64) 40c 000ff205 company_id 000ff2 | 410 00000fcf device_id 0500000fcf | EUI-64 000ff20500000fcf root directory ----------------------------------------------------------------- 414 0006c1b7 directory_length 6, crc 49591 418 03000ff2 vendor 41c 8100000a --> descriptor leaf at 444 420 17001640 model 424 81000011 --> descriptor leaf at 468 428 0c0083c0 node capabilities per IEEE 1394 42c d1000001 --> unit directory at 430 unit directory at 430 ----------------------------------------------------------------- 430 00040b97 directory_length 4, crc 2967 434 1200a02d specifier id: 1394 TA 438 13010001 version: AV/C 43c 17001640 model 440 81000010 --> descriptor leaf at 480 descriptor leaf at 444 ----------------------------------------------------------------- 444 0008a886 leaf_length 8, crc 43142 448 00000000 textual descriptor 44c 00000000 minimal ASCII 450 4c6f7564 "Loud" 454 20546563 " Tec" 458 686e6f6c "hnol" 45c 6f676965 "ogie" 460 7320496e "s In" 464 632e0000 "c." descriptor leaf at 468 ----------------------------------------------------------------- 468 00059fcf leaf_length 5, crc 40911 46c 00000000 textual descriptor 470 00000000 minimal ASCII 474 4f6e7978 "Onyx" 478 20313634 " 164" 47c 30690000 "0i" descriptor leaf at 480 ----------------------------------------------------------------- 480 00059fcf leaf_length 5, crc 40911 484 00000000 textual descriptor 488 00000000 minimal ASCII 48c 4f6e7978 "Onyx" 490 20313634 " 164" 494 30690000 "0i" [0]: [FFADO-user] Mackie 1640i issues (finer details) https://sourceforge.net/p/ffado/mailman/message/35229260/ Tested-by: Seth O'Bannion <saobannion@gmail.com> Signed-off-by: Takashi Sakamoto <o-takashi@sakamocchi.jp> Signed-off-by: Takashi Iwai <tiwai@suse.de>
2016-03-31ALSA: oxfw: delayed registration of sound cardTakashi Sakamoto
Some oxfw based units tends to fail asynchronous communication when IEEE 1394 bus is under bus-reset state. When registering sound card instance at unit probe callback, userspace applications can be involved to the state. This commit postpones the registration till the bus is calm.

2015-12-22ALSA: oxfw: add stream format quirk for SCS.1 modelsTakashi Sakamoto
As long as I investigate SCS.1m, this model reports to transfer/receive PCM data channels/MIDI conformant data channels in tx/rx AMDTP packet. There's a contradiction that this model actually has no analog/digital capture port for PCM frames and no physical MIDI ports. I guess that SCS.1d also has the contradiction. This model has no analog/digital ports for PCM frames and no physical MIDI ports, thus it requires no streaming functionality. This commit adds some modification codes to handle the contradiction, as much as possible. Unfortunately, this module adds one PCM playback substream for SCS.1d so as SCS.1m.

2015-12-22ALSA: oxfw: obsolete scs1x moduleTakashi Sakamoto
Now ALSA oxfw driver gains functionalities which scs1x module has. This commit obsoletes the scs1x module, and adds a line of MODULE_ALIAS to load oxfw module instead of scs1x module. In scs1x module, the name of 'shortname' field is fixed as 'SCS1x'. This field is used to name MIDI ports for both of SCS.1m and SCS.1d. This is not good because typically some SCS.1m and SCS.1d are used in the same system. It's better to distinguish them according to name of the ports. This commit applies model name in config ROM to the 'shortname'. For the name of 'driver' and 'longname', this commit uses the same way applied to the other models. This change may not bring disadvantages to users because userspace applications use ALSA rawmidi or seq interface and these interfaces are not influenced by them directly.

2015-12-22ALSA: oxfw: add scs1x layerTakashi Sakamoto
Stanton Controllers and Systems 1 (SCS.1) series is supported by ALSA scs1x driver. This driver just supports MIDI functionality. On the other hand, models in this series are based on OXFW971 and ALSA OXFW driver can support them. SCS.1 series has MIDI functionality to control its surface state such as LED lighting. When operating physical knobs and faders, the models generate MIDI messages. These MIDI messages are transferred by asynchronous transactions. These transactions are really model-specific and ALSA OXFW driver requires the functionality so as scs1x module implements. This commit adds scs1x layer as a preparation to merge scs1x driver to oxfw driver. Signed-off-by: Takashi Sakamoto <o-takashi@sakamocchi.jp> Signed-off-by: Takashi Iwai <tiwai@suse.de>

2015-09-24ALSA: oxfw: add Mackie Onyx Satellite quirk to inform wrong value in 'dbs' ↵Takashi Sakamoto
field in tx CIP header Mackie Onyx Satellite has two usage; standalone and with base station. These two modes has different stream formats. In standalone mode, rx data block includes 2 Multi Bit Linear Audio (MBLA) data channels and tx data block includes 2. With base station, they're 6 and 2. Although, with base station, the actual tx packet include wrong value in 'dbs' field in its CIP header. This quirk causes packet streaming layer to detect packet discontinuity and to stop PCM substream. This is a response of 'single' subfunction 'extended stream format information' command in AV/C Stream Format Information Specification 1.1. It means that a data block in tx packets includes 2 MBLA data channels. $ ./firewire-request /dev/fw1 fcp 0x01ffbfc001000000ffffffff response: 000: 0c ff bf c0 01 00 00 00 ff 00 90 40 03 02 01 02 response: 010: 06 Current OXFW driver parses the response and detects stream formats correctly. $ cat /proc/asound/card1/firewire/formation ...

2015-02-23ALSA: fireworks/bebob/dice/oxfw: add reference-counting for FireWire unitTakashi Sakamoto
Fireworks and Dice drivers try to touch instances of FireWire unit after sound card object is released, while references to the unit is decremented in .remove(). When unplugging during streaming, sound card object is released after .remove(), thus Fireworks and Dice drivers causes GPF or Null-pointer-dereferencing to application processes because an instance of FireWire unit was already released. This commit adds reference-counting for FireWire unit in drivers to allow them to touch an instance of FireWire unit after .remove(). In most case, any operations after .remove() may be failed safely.

2014-12-10ALSA: oxfw: Add support AMDTP in-streamTakashi Sakamoto
Previous commit adds support for some devices which can capture PCM samples. These devices transmit AMDTP stream in non-blocking mode. This commit adds functionality to handle AMDTP incoming stream. OXFW seems to have two quirks: - Transmits packets with non-zero dbc in its beginning - Transmits packets with wrong values in syt field For the first quirk, this commit adds CIP_SKIP_INIT_DBC_CHECK flag for incoming stream to skip first check of dbc. For the second quirk, this commit doesn't add duplex stream which Fireworks/BeBoB drivers use. So OXFW driver generates syt value for outgoing stream. Here are examples of a sequence of packets transmitted by Behringer F-Control Audio 202. There are differences between sequences of syt value when OXFW driver transfers outgoing stream or not. When driver gives no outgoing stream: Index Payload CIP_Header_0 CIP_Header_1 38 14 00020092 900103D1 39 12 00020098 900102FF 40 12 0002009D 9001027F 41 14 000200A2 90010396 42 14 000200A8 900102E8 43 12 000200AE 90010219 44 14 000200B3 90010331 45 12 000200B9 9001025F 46 14 000200BE 90010376 47 12 000200C4 900102A1 00 12 000200C9 9001023E 01 14 000200CE 90010358 02 12 000200D4 90010289 03 16 000200D9 900103A3 04 12 000200E0 900102DD 05 14 000200E5 900103F1 06 12 000200EB 90010335 07 12 000200F0 90010263 08 14 000200F5 9001037C 09 12 000200FB 900102AE When driver gives outgoing stream: Index Payload CIP_Header_0 CIP_Header_1 38 12 000200BD 900104A8 39 14 000200C2 900104A8 40 12 000200C8 900104AC 41 14 000200CD 900104A9 42 12 000200D3 900104B1 43 14 000200D8 900104A8 44 12 000200DE 900104AA 45 14 000200E3 900104A9 46 14 000200E9 900104AE 47 12 000200EF 900104A8 00 14 000200F4 900104AD 01 12 000200FA 900104A7 02 14 000200FF 900104A9 03 12 00020005 900104A9 04 14 0002000A 900104B1 05 12 00020010 900104AA 06 14 00020015 900104AD 07 12 0002001B 900104A7 08 14 00020020 900104AC 09 12 00020026 900104A7 Signed-off-by: Takashi Sakamoto <o-takashi@sakamocchi.jp> Acked-by: Clemens Ladisch <clemens@ladisch.de> Signed-off-by: Takashi Iwai <tiwai@suse.de>
