2024-02-19ALSA: oxfw: add support for Miglia Harmony AudioTakashi Sakamoto1-0/+3
Miglia Technology ships Harmony Audio 2004. It uses Oxford Semiconductor OXFW970 for communication function in IEEE 1394 bus. This commit adds support for the model. In my opinion, the firmware of ASIC is really the initial stage, since it has the following quirks. * It skips several isochronous cycles to transmit isochronous packets when receiving any asynchronous transaction. * The value of dbc field in the transmitted packet is the number of accumulated quadlets in CIP payload, instead of the accumulated data blocks. Furthermore, the value includes the quadlets of CIP payload in the packet. * It neither supports AV/C Stream Format Information command nor AV/C Extended Stream Format Information command. * The vendor and model information in root directory of configuration ROM includes some mistakes. Additionally, when operating at 96.0 kHz, it often skips much isochronous cycles to transmit the isochronous packets. The issue is detected as cycle discontinuity and ALSA PCM application receives -EIO at any operation for PCM substream. I have never found any workaround yet. $ config-rom-pretty-printer < /sys/bus/firewire/devices/fw1/config_rom ROM header and bus information block ----------------------------------------------------------------- 1024 04249e04 bus_info_length 4, crc_length 36, crc 40452 1028 31333934 bus_name "1394" 1032 20ff5003 irmc 0, cmc 0, isc 1, bmc 0, cyc_clk_acc 255, max_rec 5 (64) 1036 0030e002 company_id 0030e0 | 1040 00454647 device_id 8594474567 | EUI-64 13757098081207879 root directory ----------------------------------------------------------------- 1044 00062d69 directory_length 6, crc 11625 1048 030030e0 vendor 1052 8100000a --> descriptor leaf at 1092 1056 1700f970 model 1060 81000011 --> descriptor leaf at 1128 1064 0c0083c0 node capabilities: per IEEE 1394 1068 d1000001 --> unit directory at 1072 unit directory at 1072 ----------------------------------------------------------------- 1072 00046ff9 directory_length 4, crc 28665 (should be 43676) 1076 1200a02d specifier id 1080 13010001 version 1084 1700f970 model 1088 8100000f --> descriptor leaf at 1148 descriptor leaf at 1092 ----------------------------------------------------------------- 1092 00085f8a leaf_length 8, crc 24458 1096 00000000 textual descriptor 1100 00000000 minimal ASCII 1104 4d69676c "Migl" 1108 69612054 "ia T" 1112 6563686e "echn" 1116 6f6c6f67 "olog" 1120 79204c74 "y Lt" 1124 642e0000 "d." descriptor leaf at 1128 ----------------------------------------------------------------- 1128 00040514 leaf_length 4, crc 1300 1132 00000000 textual descriptor 1136 00000000 minimal ASCII 1140 4f584657 "OXFW" 1144 20393730 " 970" descriptor leaf at 1148 ----------------------------------------------------------------- 1148 0005a1dc leaf_length 5, crc 41436 1152 00000000 textual descriptor 1156 00000000 minimal ASCII 1160 4861726d "Harm" 1164 6f6e7941 "onyA" 1168 7564696f "udio" Signed-off-by: Takashi Sakamoto <o-takashi@sakamocchi.jp> Link: https://lore.kernel.org/r/20240218074128.95210-5-o-takashi@sakamocchi.jp Signed-off-by: Takashi Iwai <tiwai@suse.de>

2021-10-28ALSA: oxfw: fix functional regression for Mackie Onyx 1640i in v5.14 or laterTakashi Sakamoto1-0/+5
A user reports functional regression for Mackie Onyx 1640i that the device generates slow sound with ALSA oxfw driver which supports media clock recovery. Although the device is based on OXFW971 ASIC, it does not transfer isochronous packet with own event frequency as expected. The device seems to adjust event frequency according to events in received isochronous packets in the beginning of packet streaming. This is unknown quirk. This commit fixes the regression to turn the recovery off in driver side. As a result, nominal frequency is used in duplex packet streaming between device and driver. For stability of sampling rate in events of transferred isochronous packet, 4,000 isochronous packets are skipped in the beginning of packet streaming.

2021-08-12ALSA: oxfw: fix functioal regression for silence in Apogee Duet FireWireTakashi Sakamoto1-0/+5
OXFW 971 has no function to use the value in syt field of received isochronous packet for playback timing generation. In kernel prepatch for v5.14, ALSA OXFW driver got change to send NO_INFO value in the field instead of actual timing value. The change brings Apogee Duet FireWire to generate no playback sound, while output meter moves. As long as I investigate, _any_ value in the syt field takes the device to generate sound. It's reasonable to think that the device just ignores data blocks in packet with NO_INFO value in its syt field for audio data processing. This commit adds a new flag for the quirk to fix regression.

2019-10-18ALSA: oxfw: share PCM buffer size for both directionTakashi Sakamoto1-1/+2
This commit allows ALSA oxfw driver to share PCM buffer size for both capture and playback PCM substream. When AMDTP domain starts for one of the PCM substream, buffer size of the PCM substream is stores to AMDTP domain structure. Some AMDTP streams have already run with the buffer size when another PCM substream starts, therefore the PCM substream has a constraint to its buffer size.

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 ...

2014-12-10ALSA: oxfw: Add support AMDTP in-streamTakashi Sakamoto1-6/+18
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>
2014-12-10ALSA: oxfw: Change the way to start streamTakashi Sakamoto1-1/+2
In past commit, this driver can keep stream formations for each sampling rate. So its stream functionality can decide stream formations with given some parameters. This commit moves related codes from PCM functionality to stream functionality. Furthermore, to set stream format correctly, this commit uses AV/C Stream Format Information command instead of AV/C Input/Output Plug Signal Format command.

2014-12-10ALSA: oxfw: Change the way to make PCM rules/constraintsTakashi Sakamoto1-3/+18
In previous commit, this driver can get to know stream formations at each supported sampling rates. This commit uses it to make PCM rules/constraints and obsoletes hard-coded rules/constraints. For this purpose, this commit adds 'struct snd_oxfw_stream_formation' and snd_oxfw_stream_parse_format() to parse data channel formation of data block. According to datasheet of OXFW970/971, they support 32.0kHz to 196.0kHz. As long as developers investigate, some devices are confirmed to have several formats for the same sampling rate.

2014-12-10ALSA: oxfw: Add support for AV/C stream format command to get/set supported ↵Takashi Sakamoto1-0/+33
stream formation OXFW970/971 may supports AV/C Stream Format Information Specification 1.1 Working Draft (Apr 2005, 1394TA). By using this command, drivers can get to know stream formations which device supports. This commit adds 'EXTENDED STREAM FORMAT INFORMATION' command. This command has two subfunctions, 'SINGLE' and 'LIST'. Drivers can use 'SINGLE' subfunction to know/set current formation of AMDTP stream, Drivers can use 'LIST' subfunction to know an available formation of AMDTP stream in a certain sampling rate. But some devices don't implement the 'LIST' subfunction. So this commit uses an assumption that 'if they don't implement it, they don't change stream formation depending on current each sampling rate'. With this assumption, this driver generates formations for such devices by: 1.getting current formation by SINGLE subfunction 2.getting supported sampling rates 3.applying current formation for all of supported sampling rates Followed commit implements a parser of this format information.

2014-12-10ALSA: oxfw: Change the way to name cardTakashi Sakamoto1-2/+2
This is a preparation for more models. In following commit, members of 'struct snd_card' related to name becomes to consists of vendor and model strings in device's config-rom. Current supported devices also has strings in their config rom, but the strings are too long to name sound card, thus this driver still keep hard-coded vendor and model names for them.
