2019-02-26ALSA: firewire-motu: fix construction of PCM frame for capture directionTakashi Sakamoto1-1/+3
In data blocks of common isochronous packet for MOTU devices, PCM frames are multiplexed in a shape of '24 bit * 4 Audio Pack', described in IEC 61883-6. The frames are not aligned to quadlet. For capture PCM substream, ALSA firewire-motu driver constructs PCM frames by reading data blocks byte-by-byte. However this operation includes bug for lower byte of the PCM sample. This brings invalid content of the PCM samples. This commit fixes the bug.

2019-02-26ALSA: bebob: use more identical mod_alias for Saffire Pro 10 I/O against ↵Takashi Sakamoto1-1/+13
Liquid Saffire 56 ALSA bebob driver has an entry for Focusrite Saffire Pro 10 I/O. The entry matches vendor_id in root directory and model_id in unit directory of configuration ROM for IEEE 1394 bus. On the other hand, configuration ROM of Focusrite Liquid Saffire 56 has the same vendor_id and model_id. This device is an application of TCAT Dice (TCD2220 a.k.a Dice Jr.) however ALSA bebob driver can be bound to it randomly instead of ALSA dice driver. At present, drivers in ALSA firewire stack can not handle this situation appropriately. This commit uses more identical mod_alias for Focusrite Saffire Pro 10 I/O in ALSA bebob driver. $ python2 crpp < /sys/bus/firewire/devices/fw1/config_rom ROM header and bus information block ----------------------------------------------------------------- 400 042a829d bus_info_length 4, crc_length 42, crc 33437 404 31333934 bus_name "1394" 408 f0649222 irmc 1, cmc 1, isc 1, bmc 1, pmc 0, cyc_clk_acc 100, max_rec 9 (1024), max_rom 2, gen 2, spd 2 (S400) 40c 00130e01 company_id 00130e | 410 000606e0 device_id 01000606e0 | EUI-64 00130e01000606e0 root directory ----------------------------------------------------------------- 414 0009d31c directory_length 9, crc 54044 418 04000014 hardware version 41c 0c0083c0 node capabilities per IEEE 1394 420 0300130e vendor 424 81000012 --> descriptor leaf at 46c 428 17000006 model 42c 81000016 --> descriptor leaf at 484 430 130120c2 version 434 d1000002 --> unit directory at 43c 438 d4000006 --> dependent info directory at 450 unit directory at 43c ----------------------------------------------------------------- 43c 0004707c directory_length 4, crc 28796 440 1200a02d specifier id: 1394 TA 444 13010001 version: AV/C 448 17000006 model 44c 81000013 --> descriptor leaf at 498 dependent info directory at 450 ----------------------------------------------------------------- 450 000637c7 directory_length 6, crc 14279 454 120007f5 specifier id 458 13000001 version 45c 3affffc7 (immediate value) 460 3b100000 (immediate value) 464 3cffffc7 (immediate value) 468 3d600000 (immediate value) descriptor leaf at 46c ----------------------------------------------------------------- 46c 00056f3b leaf_length 5, crc 28475 470 00000000 textual descriptor 474 00000000 minimal ASCII 478 466f6375 "Focu" 47c 73726974 "srit" 480 65000000 "e" descriptor leaf at 484 ----------------------------------------------------------------- 484 0004a165 leaf_length 4, crc 41317 488 00000000 textual descriptor 48c 00000000 minimal ASCII 490 50726f31 "Pro1" 494 30494f00 "0IO" descriptor leaf at 498 ----------------------------------------------------------------- 498 0004a165 leaf_length 4, crc 41317 49c 00000000 textual descriptor 4a0 00000000 minimal ASCII 4a4 50726f31 "Pro1" 4a8 30494f00 "0IO" $ python2 crpp < /sys/bus/firewire/devices/fw1/config_rom ROM header and bus information block ----------------------------------------------------------------- 400 040442e4 bus_info_length 4, crc_length 4, crc 17124 404 31333934 bus_name "1394" 408 e0ff8112 irmc 1, cmc 1, isc 1, bmc 0, pmc 0, cyc_clk_acc 255, max_rec 8 (512), max_rom 1, gen 1, spd 2 (S400) 40c 00130e04 company_id 00130e | 410 018001e9 device_id 04018001e9 | EUI-64 00130e04018001e9 root directory ----------------------------------------------------------------- 414 00065612 directory_length 6, crc 22034 418 0300130e vendor 41c 8100000a --> descriptor leaf at 444 420 17000006 model 424 8100000e --> descriptor leaf at 45c 428 0c0087c0 node capabilities per IEEE 1394 42c d1000001 --> unit directory at 430 unit directory at 430 ----------------------------------------------------------------- 430 000418a0 directory_length 4, crc 6304 434 1200130e specifier id 438 13000001 version 43c 17000006 model 440 8100000f --> descriptor leaf at 47c descriptor leaf at 444 ----------------------------------------------------------------- 444 00056f3b leaf_length 5, crc 28475 448 00000000 textual descriptor 44c 00000000 minimal ASCII 450 466f6375 "Focu" 454 73726974 "srit" 458 65000000 "e" descriptor leaf at 45c ----------------------------------------------------------------- 45c 000762c6 leaf_length 7, crc 25286 460 00000000 textual descriptor 464 00000000 minimal ASCII 468 4c495155 "LIQU" 46c 49445f53 "ID_S" 470 41464649 "AFFI" 474 52455f35 "RE_5" 478 36000000 "6" descriptor leaf at 47c ----------------------------------------------------------------- 47c 000762c6 leaf_length 7, crc 25286 480 00000000 textual descriptor 484 00000000 minimal ASCII 488 4c495155 "LIQU" 48c 49445f53 "ID_S" 490 41464649 "AFFI" 494 52455f35 "RE_5" 498 36000000 "6" Cc: <stable@vger.kernel.org> # v3.16+ Fixes: 25784ec2d034 ("ALSA: bebob: Add support for Focusrite Saffire/SaffirePro series") Signed-off-by: Takashi Sakamoto <o-takashi@sakamocchi.jp> Signed-off-by: Takashi Iwai <tiwai@suse.de>

2019-01-28ALSA: dice: add support for Solid State Logic Duende Classic/MiniTakashi Sakamoto1-1/+11
Duende Classic was produced by Solid State Logic in 2006, as a first model of Duende DSP series. The following model, Duende Mini was produced in 2008. They are designed to receive isochronous packets for PCM frames via IEEE 1394 bus, perform signal processing by downloaded program, then transfer isochronous packets for converted PCM frames. These two models includes the same embedded board, consists of several ICs below: - Texus Instruments Inc, TSB41AB3 for physical layer of IEEE 1394 bus - WaveFront semiconductor, DICE II STD ASIC for link/protocol layer - Altera MAX 3000A CPLD for programs - Analog devices, SHARC ADSP-21363 for signal processing (4 chips) This commit adds support for the two models to ALSA dice driver. Like support for the other devices, packet streaming is just available.

2019-01-24ALSA: fireface: comment cleanup about destination address of async ↵Takashi Sakamoto3-29/+48
transactions for MIDI messages In Fireface series, registration of higher 4 bytes of destination address for asynchronous transaction of MIDI messages is done by a write transaction to model-specific register. On the other hand, registration of lower 4 bytes of the address is selectable from 4 options. A register for this registration includes the other purpose options such as input attenuation. Thus this driver expects userspace applications to configure the register. Actual behaviour for the asynchronous transaction is different depending on protocols. In former protocol, destination offset of each transaction is the same as the registered address even if it is block request. In latter models, destination offset of each transaction is the offset of previous transaction plus 4 byte and the transaction is quadlet request. This commit cleanups comments about the above mechanism. Signed-off-by: Takashi Sakamoto <o-takashi@sakamocchi.jp> Signed-off-by: Takashi Iwai <tiwai@suse.de>
2019-01-22ALSA: fireface: support rx MIDI functionality for Fireface UCXTakashi Sakamoto4-2/+99
In latter model of Fireface series, asynchronous transaction includes a prefix byte to indicate the way to decode included MIDI bytes. Upper 4 bits of the prefix byte indicates port number, and the rest 4 bits indicate the way to decode rest of bytes for MIDI messages. Basically the rest bits indicates the number of bytes for MIDI message. However, if the last byte of each MIDi message is included, the rest bits are 0xf. For example: message: f0 00 00 66 14 20 00 00 f7 offset: content (big endian, port 0) '0030: 0x02f00000 '0030: 0x03006614 '0030: 0x03200000 '0030: 0x0ff70000 This commit supports encoding scheme for the above and allows applications to transfer MIDI messages via ALSA rawmidi interface. An unused member (running_status) is reused to keep state of transmission of system exclusive messages.

2019-01-22ALSA: fireface: support tx MIDI functionality of Fireface UCXTakashi Sakamoto2-14/+54
Fireface UCX transfers asynchronous transactions for MIDI messages. One transaction includes quadlet data therefore it can transfer 3 message bytes as maximum. Base address of the destination is configured by two settings; a register for higher 8 byte of the address, and a bitflag to option register indicates lower 8byte. The register for higher address is 0x'ffff'0000'0034. Unfortunately, firmware v24 includes a bug to ignore registered value for the destination address and transfers to 0x0001xxxxxxxx always. This driver doesn't work well if the bug exists, therefore users should install the latest firmware (v27). The bitflag is a part of value to be written to option register (0x'ffff'0000'0014). lower addr: bitflag (little endian) '0000'0000: 0x00002000 '0000'0080: 0x00004000 '0000'0100: 0x00008000 '0000'0180: 0x00010000 This register includes more options but they are not relevant to packet streaming or MIDI functionality. This driver don't touch it. Furthermore, the transaction is sent to address offset incremented by 4 byte to the offset in previous time. When it reaches base address plus 0x7c, next offset is the base address. Content of the transaction includes a prefix byte. Upper 4 bits of the byte indicates port number, and the rest 4 bits indicate the way to decode rest of bytes for MIDI message. Except for system exclusive messages, the rest bits are the same as status bits of the message without channel bits. For system exclusive messages, the rest bits are encoded according to included message bytes. For example: message: f0 7e 7f 09 01 f7 offset: content (little endian, port 0) '0000: 0x04f07e7f '0004: 0x070901f7 message: f0 00 00 66 14 20 00 00 00 f7 offset: content (little endian, port 1) '0014: 0x14f00000 '0018: 0x14661420 '001c: 0x14000000 '0020: 0x15f70000 message: f0 00 00 66 14 20 00 00 f7 offset: content (little endian, port 0) '0078: 0x04f00000 '007c: 0x04661420 '0000: 0x070000f7 This commit supports decoding scheme for the above and allows applications to receive MIDI messages via ALSA rawmidi interface. The lower 8 bytes of destination address is fixed to 0x'0000'0000, thus this driver expects userspace applications to configure option register with bitflag 0x00002000 in advance.

This commit fixes hard-coded model-id for an unit of Apogee Ensemble with a correct value. This unit uses DM1500 ASIC produced ArchWave AG (formerly known as BridgeCo AG). I note that this model supports three modes in the number of data channels in tx/rx streams; 8 ch pairs, 10 ch pairs, 18 ch pairs. The mode is switched by Vendor-dependent AV/C command, like: $ cd linux-firewire-utils $ ./firewire-request /dev/fw1 fcp 0x00ff000003dbeb0600000000 (8ch pairs) $ ./firewire-request /dev/fw1 fcp 0x00ff000003dbeb0601000000 (10ch pairs) $ ./firewire-request /dev/fw1 fcp 0x00ff000003dbeb0602000000 (18ch pairs) When switching between different mode, the unit disappears from IEEE 1394 bus, then appears on the bus with different combination of stream formats. In a mode of 18 ch pairs, available sampling rate is up to 96.0 kHz, else up to 192.0 kHz. $ ./hinawa-config-rom-printer /dev/fw1 { 'bus-info': { 'adj': False, 'bmc': True, 'chip_ID': 21474898341, 'cmc': True, 'cyc_clk_acc': 100, 'generation': 2, 'imc': True, 'isc': True, 'link_spd': 2, 'max_ROM': 1, 'max_rec': 512, 'name': '1394', 'node_vendor_ID': 987, 'pmc': False}, 'root-directory': [ ['HARDWARE_VERSION', 19], [ 'NODE_CAPABILITIES', { 'addressing': {'64': True, 'fix': True, 'prv': False}, 'misc': {'int': False, 'ms': False, 'spt': True}, 'state': { 'atn': False, 'ded': False, 'drq': True, 'elo': False, 'init': False, 'lst': True, 'off': False}, 'testing': {'bas': False, 'ext': False}}], ['VENDOR', 987], ['DESCRIPTOR', 'Apogee Electronics'], ['MODEL', 126702], ['DESCRIPTOR', 'Ensemble'], ['VERSION', 5297], [ 'UNIT', [ ['SPECIFIER_ID', 41005], ['VERSION', 65537], ['MODEL', 126702], ['DESCRIPTOR', 'Ensemble']]], [ 'DEPENDENT_INFO', [ ['SPECIFIER_ID', 2037], ['VERSION', 1], [(58, 'IMMEDIATE'), 16777159], [(59, 'IMMEDIATE'), 1048576], [(60, 'IMMEDIATE'), 16777159], [(61, 'IMMEDIATE'), 6291456]]]]} Signed-off-by: Takashi Sakamoto <o-takashi@sakamocchi.jp> Signed-off-by: Takashi Iwai <tiwai@suse.de>

This commit adds a functionality to multiplex PCM frames into isochronous packets and demultiplex PCM frames from isochronous packets for ALSA PCM applications. Fireface 800 voluntarily maintains resources for tx isochronous communication. It performs reservation of isochronous channel and allocation/update of bandwidth in some cases below: - at a first request to allocation after bus resets - at requests to allocation when further bandwidth is required When request is grant and the unit is prepared, read data from 0x0000801c0008 represents isochronous channel for tx stream, then the unit can handle requests to start communication. If driver send the request without checking the register, the unit takes panic to continue bus resets. The unit starts transmission of tx packets after receiving several rx packets from driver. I note that the unit can process tx/rx packets and generate/record sound regardless of HOST LED. Signed-off-by: Takashi Sakamoto <o-takashi@sakamocchi.jp> Signed-off-by: Takashi Iwai <tiwai@suse.de>

2018-12-16ALSA: fireface: fix for state to fetch PCM framesTakashi Sakamoto1-1/+1
According to my memo at hand and saved records, writing 0x00000001 to SND_FF_REG_FETCH_PCM_FRAMES disables fetching PCM frames in corresponding channel, however current implement uses reversed logic. This results in muted volume in device side during playback. This commit corrects the bug.

2018-12-16ALSA: firewire-lib: fix wrong handling payload_length as payload_quadletTakashi Sakamoto1-1/+3
In IEC 61883-1/6 engine of ALSA firewire stack, a packet handler has a second argument for 'the number of bytes in payload of isochronous packet'. However, an incoming packet handler without CIP header uses the value as 'the number of quadlets in the payload'. This brings userspace applications to receive the number of PCM frames as four times against real time. This commit fixes the bug.

2018-12-11ALSA: fireface: add support for Fireface 800 with MIDI functionality onlyTakashi Sakamoto5-13/+70
Fireface 800 is a flagship model of RME GmbH for audio and music units on IEEE 1394 bus, shipped 2004. This model consists of four chips: - TI TSB81BA3D for physical layer on cable environment of EEE 1394 bus - TI TSB82AA2 for link layer for 1394 OHCI bus bridge to PCI bus - Xilinx Spartan-3 FPGA XC3S400 - Xilinx High-Performance CPLD XC9572XL This commit adds support Fireface 800. In this time, the support is restricted to its MIDI functionality, thus this commit adds some condition statements to avoid touching streaming functionality. Unlike Fireface 400, Fireface 800 has no functionality to suppress asynchronous transactions for MIDI messages except for unregister of listen address in controller side, thus the feature is available as is.

2018-11-23ALSA: firewire-tascam: queue events for change of control surfaceTakashi Sakamoto3-1/+41
Units of TASCAM FireWire series transfer image of states of the unit in tx isochronous packets. Demultiplexing of the states from the packets is done in software interrupt context regardless of any process context. In a view of userspace applications, it needs to have notification mechanism to catch change of the states. This commit implements a queue to store events for the notification. The image of states includes fluctuating data such as level of gain/volume for physical input/output and position of knobs. Therefore the events are queued corresponding to some control features only. Furthermore, the queued events are planned to be consumed by userspace applications via ALSA hwdep interface. This commit suppresses event queueing when no applications open the hwdep interface. However, the queue is maintained in an optimistic scenario, thus without any care against overrrun. This is reasonable because target events are useless just to handle PCM frames. It starts queueing when an usespace application opens hwdep interface, thus it's expected to read the queued events steadily.

2018-10-30ALSA: firewire-lib: fix insufficient PCM rule for period/buffer sizeTakashi Sakamoto1-48/+9
In a former commit, PCM constraint based on LCM of SYT_INTERVAL was obsoleted with PCM rule. However, the new PCM rule brings -EINVAL in some cases that max/min values of size of buffer/period is not multiples of one of values of SYT_INTERVAL. For example, pulseaudio always fail to configure PCM substream. This commit changes strategy for the PCM rule. Although the buggy rules had a single dependency (rate from period, period from rate, rate from buffer, buffer from rate), a revised rule has double dependencies (period from period/rate, buffer from buffer/rate). A step of value is calculated with table of SYT_INTERVAL and list of available rates. This prevents interval template which brings -EINVAL to a call of snd_interval_refine().
