2017-04-12ALSA: firewire-lib: cache maximum length of payload to reduce function callsTakashi Sakamoto2-4/+6
During packet streaming, maximum length of payload for isochronous packet is invariable, therefore no need to recalculate. Current ALSA IEC 61883-1/6 engine calls a function to calculate it 8,000 or more times per second for incoming packet processing. This commit adds a member to have maximum length of payload into 'struct amdtp_stream', to reduces the function calls. At first callback from isochronous context, the length is calculated and stored for later processing.

2017-04-11ALSA: firewire-motu: add tracepoints for messages for unique protocolTakashi Sakamoto2-0/+67
MOTU units transfer/receive messages in each data block of their isochronous packet payload. A part of content in the message is cleard for MIDI message transmission, while the rest is unknown yet. Additional features are required to assist users and developers to reveal the details. This commit adds tracepoints for the purpose. The tracepoints are designed for MOTU's protocol version 2 and 3 (Protocol version 1 is not upstreamed yet). In the tracepoints, events are probed to gather first two 24 bit data chunks of each data block. The chunks are formatted into elements of 64 bit array with padding in MSB.

2017-04-11ALSA: firewire-motu: add tracepoints for SPH in IEC 61883-1 fashionTakashi Sakamoto3-0/+95
Unique protocol is used for MOTU FireWire series. In this protocol, data block format is not compliant to AM824 in IEC 61883-1/6. Each of the data block consists of 24 bit data chunks, except for a first quadlet. The quadlet is used for source packet header (SPH) described in IEC 61883-1. The sequence of SPH seems to represent presentation timestamp corresponding to included data. Developers have experienced that invalid sequence brings disorder of units in the series. Unfortunately, current implementation of ALSA IEC 61883-1/6 engine and firewire-motu driver brings periodical noises to the units at sampling transmission frequency based on 44.1 kHz. The engine generates the SPH with even interval and this mechanism seems not to be suitable to the units. Further work is required for this issue and infrastructure is preferable to assist the work. This commit adds tracepoints for the purpose. In the tracepoints, events are probed to gather the SPHs from each data blocks.

Unique protocol is used for RME Fireface series. In this protocol, payload format for isochronous packet is not compliant to CIP in IEC 61883-1/6. The packet includes data blocks just with data channels, without headers and any metadata. In previous commits, ALSA IEC 61883-1/6 engine supports this protocol.

2017-04-05ALSA: fireface: add support for PCM functionalityTakashi Sakamoto4-1/+404
This commit adds PCM functionality to transmit/receive PCM frames on isochronous packet streaming. This commit enables userspace applications to start/stop packet streaming via ALSA PCM interface. Sampling rate requested by applications is used as sampling transmission frequency of IEC 61883-1/6packet streaming. As I described in followed commits, units in this series manages sampling clock frequency independently of sampling transmission frequency, and they supports resampling between their packet streaming/data block processing layer and sampling data processing layer. This commit take this driver to utilize these features for usability. When internal clock is selected as source signal of sampling clock, this driver allows user space applications to start PCM substreams at any rate which packet streaming engine supports as sampling transmission frequency. In this case, this driver expects units to perform resampling PCM frames for rx/tx packets when sampling clock frequency and sampling transmission frequency are mismatched. This is for daily use cases. When any external clock is selected as the source signal, this driver gets configured sampling rate from units, then restricts available sampling rate to the rate for PCM applications. This is for studio use cases. Models in this series supports 64.0/128.0 kHz of sampling rate, however these frequencies are not supported by IEC 61883-6 as sampling transmission frequency. Therefore, packet streaming engine of ALSA firewire stack can't handle them. When units are configured to use any external clock as source signal of sampling clock and one of these unsupported rate is configured as rate of the sampling clock, this driver returns EIO to user space applications. Anyway, this driver doesn't voluntarily configure parameters of sampling clock. It's better for users to work with appropriate user space implementations to configure the parameters in advance of usage.

2017-04-05ALSA: fireface: add stream management functionalityTakashi Sakamoto4-1/+267
This commit adds management functionality for packet streaming. As long as investigating Fireface 400, there're three modes depending on sampling transmission frequency. The number of data channels in each data block is different depending on the mode. The set of available data channels for each mode might be different for each protocol and model. The length of registers for the number of isochronous channel is just three bits, therefore 0-7ch are available. When bus reset occurs on IEEE 1394 bus, the device discontinues to transmit packets. This commit aborts PCM substreams at bus reset handler. As I described in followed commits, The device manages its sampling clock independently of sampling transmission frequency against IEC 61883-6. Thus, it's a lower cost to change the sampling transmission frequency, while data fetch between streaming layer and DSP require larger buffer for resampling. As a result, device latency might tend to be larger than ASICs for IEC 61883-1/6 such as DM1000/DM1100/DM1500 (BeBoB), DiceII/TCD2210/TCD2220/TCD3070 and OXFW970/971.

2017-04-05ALSA: fireface: add unique data processing layerTakashi Sakamoto3-1/+164
As long as investigating Fireface 400, format of payload of each isochronous packet is not IEC 61883-1/6, thus its format of data block is not AM824. The remarkable points of the format are: * The payload just consists of some data channels of quadlet size without CIP header. * Each data channels includes data aligned to little endian order. * One data channel consists of two parts; 8 bit ancillary field and 24 bit PCM frame. Due to lack of CIP headers, rx/tx packets include no CIP headers and different way to check packet discontinuity. For tx packet, the ancillary field is used for counter. However, the way of counting is different depending on positions of data channels. At 44.1 kHz, ancillary field in: * 1st/6th/9th/10th/14th/17th data channels: not used for this purpose. * 2nd/18th data channels: incremented every data block (0x00-0xff). * 3rd/4th/5th/11th/12th/13th data channels: incremented every 256 data blocks (0x00-0x07). * 7th/8th/15th/16th data channels: incremented per the number of data blocks in a packet. The increment can occur per packet (0x00-0xff). For tx packet, tag of each isochronous packet is used for this purpose. The value of tag cyclically changes between 0, 1, 2 and 3 in this order. The interval is different depending on sampling transmission frequency. At 44.1/48.0 kHz, it's 256 data blocks. At 88.2 kHz, it's 96 data blocks. The number of data blocks in tx packet is exactly the same as SYT_INTERVAL. There's no empty packet or no-data packet, thus the throughput is not 8,000 packets per sec. On the other hand, the one in rx packet is 8,000 packets per sec, thus the number of data blocks is different between each packet, depending on sampling transmission frequency: * 44.1 kHz: 5 or 6 * 48.0 kHz: 5 or 6 or 7 * 88.2 kHz: 10 or 11 or 12 This commit adds data processing layer to satisfy the above specification in a policy of 'best effort'. Although PCM frames are handled for intermediate buffer to user space, the ancillary data is not handled at all to reduce CPU usage, thus counter is not checked. 0 is always used for tag of isochronous packet. Furthermore, the packet streaming layer is responsible for calculation of the number of data blocks for each packet, thus it's not exactly the same sequence from the above observation.

2017-04-05ALSA: firewire-lib: add no-header packet processingTakashi Sakamoto2-5/+81
As long as investigating Fireface 400, IEC 61883-1/6 is not applied to its packet streaming protocol. Remarks of the specific protocol are: * Each packet doesn't include CIP headers. * 64,0 and 128,0 kHz are supported. * The device doesn't necessarily transmit 8,000 packets per second. * 0, 1, 2, 3 are used as tag for rx isochronous packets, however 0 is used for tx isochronous packets. On the other hand, there's a common feature. The number of data blocks transferred in a second is the same as sampling transmission frequency. Current ALSA IEC 61883-1/6 engine already has a method to calculate it and this driver can utilize it for rx packets, as well as tx packets. This commit adds support for the transferring protocol. CIP_NO_HEADERS flag is newly added. When this flag is set: * Both of 0 (without CIP header) and 1 (with CIP header) are used as tag to handle incoming isochronous packet. * 0 (without CIP header) is used as tag to transfer outgoing isochronous packet. * Skip CIP header evaluation. * Use unique way to calculate the quadlets of isochronous packet payload. In ALSA PCM interface, 128.0 kHz is not supported, and the ALSA IEC 61883-1/6 engine doesn't support 64.0 kHz. These modes are dropped. The sequence of rx packet has a remarkable quirk about tag.

2017-04-05ALSA: fireface: add transaction supportTakashi Sakamoto4-1/+328
As long as investigating Fireface 400, MIDI messages are transferred by asynchronous communication over IEEE 1394 bus. Fireface 400 receives MIDI messages by write transactions to two addresses; 0x'0000'0801'8000 and 0x'0000'0801'9000. Each of two seems to correspond to MIDI port 1 and 2. Fireface 400 transfers MIDI messages by write transactions to certain addresses which configured by drivers. The drivers can decide upper 4 byte of the addresses by write transactions to 0x'0000'0801'03f4. For the rest part of the address, drivers can select from below options: * 0x'0000'0000 * 0x'0000'0080 * 0x'0000'0100 * 0x'0000'0180 Selected options are represented in register 0x'0000'0801'051c as bit flags. Due to this mechanism, drivers are restricted to use addresses on 'Memory space' of IEEE 1222, even if transactions to the address have some side effects. This commit adds transaction support for MIDI messaging, based on my assumption that the similar mechanism is used on the other protocols. To receive asynchronous transactions, the driver allocates a range of address in 'Memory space'. I apply a strategy to use 0x'0000'0000 as lower 4 byte of the address. When getting failure from Linux FireWire subsystem, this driver retries to allocate addresses. Unfortunately, read transaction to address 0x'0000'0801'051c returns zero always, however write transactions have effects to the other features such as status of sampling clock. For this reason, this commit delegates a task to configure this register to user space applications. The applications should set 3rd bit in LSB in little endian order.

2017-04-05ALSA: fireface: add an abstraction layer for model-specific protocolsTakashi Sakamoto1-0/+31
As of 2016, RME discontinued its Fireface series, thus it's OK for us to focus on released firmwares to drive known units. As long as investigating Fireface 400 with Windows driver and comparing the result to FFADO implementation, I can see these firmwares have different register assignments. On the other hand, according to manuals of each models, features relevant to packet streaming seem to be common, because GUIs for these models have the same options. It's reasonable to assume an abstraction layer of protocols to communicate to each models. This commit adds the abstraction layer for the protocols. This layer includes some functions to operate common features of models in this series. In IEC 61883-1/6, the sequence of packet can transfer timing information to synchronize receivers to transmitters. Units of each node on IEEE 1394 bus can generate transmitter's timing clock by handling value of SYT field in CIP header with high-precision clock. For audio and music units on IEEE 1394 bus, this recovered clock is designed to used for sampling clock to capture/generate PCM frames on DSP/ADC/DAC. (Actually, in this world, there's no units to implement this specification as is, as long as I know). Fireface series doesn't use this mechanism. Besides, It doesn't use isochronous packet with CIP header. It uses internal crystal unit as its initial sampling clock. When detecting input signals which can be available for sampling clock (e.g. ADAT input), drivers can configure units to use the signals as source of sampling clock. When something goes wrong, e.g. frequency mismatching between the signal and configured value, units fallback to the other detected signals alternatively. When detecting no alternatives, internal crystal unit is used as source of sampling clock. On manual of Fireface 400, this mechanism is described as 'Autosync'. On the units, packet streaming is controlled by write transactions to certain registers. Format of the packet, e.g. the number of data channels in a data block, is also configured by the same manner. For this purpose, .begin_session and .finish_session is added. The remarkable point of this protocol is to allow drivers to configure arbitrary sampling transmission frequency; e.g. 12.345 Hz. As long as I know, there's no actual DAC/ADC chips which support this kind of capability. I think a pair of packet streaming layer and data block processing layer is isolated from sampling data processing layer in a point of governed clock. In short, between these parts, resampling layer exists. Actually, for Fireface 400, write transactions to 0x'0000'8010'051c has an effect to change sampling clock frequency with base frequencies (32.0/44.1/48.0 kHz) and its multipliers (x2/x4), regardless of sampling transmission frequency. For this reason, the abstraction layer doesn't handle parameters for sampling clock. Instead, each implementation of .begin_session is expected to configure sampling transmission frequency. For packet streaming layer, it's enough to get current selection of source signals for the sampling clock and its frequency. In the abstraction layer, when internal crystal is selected, drivers can sets arbitrary sampling frequency, else they should follow configured frequency. For this purpose, .get_clock is added. Drivers are allows to bank up data fetching from a pair of packet streaming/data block processing layer and sampling data processing layer. This feature seems to suppress noises at starting/stopping packet streaming. For this purpose, .switch_fetching_mode is added. As I described in the above, units have remarkable mechanism to manage sampling clock and process sampling data. For debugging purpose, .dump_sync_status and .dump_clock_config are added. I don't have a need to common interface to represent the status and configuration, developers can add actual implementation of the abstraction layer as they like. Unlike PCM frames, MIDI messages are transferred by asynchronous communication over IEEE 1394 bus, thus target addresses are important for this feature. The .midi_high_addr_reg, .midi_rx_port_0_reg and .midi_rx_port_1_reg are for this purpose. I'll describe them in following commit.

2017-04-05ALSA: fireface: add model specific structureTakashi Sakamoto2-4/+19
RME Fireface series has several models and their specifications are different. Currently, we find no way to retrieve the specifications from actual devices and need to implement them in this driver. This commit adds a structure to describe model specific data. This structure has an identical name for each unit, and maximum number of data channels in each mode. I'll describe about the mode in following commits. Signed-off-by: Takashi Sakamoto <o-takashi@sakamocchi.jp> Signed-off-by: Takashi Iwai <tiwai@suse.de>
2017-04-05ALSA: fireface: postpone sound card registrationTakashi Sakamoto2-22/+67
Just after appearing on IEEE 1394 bus, this unit generates several bus resets. This is due to loading firmware from on-board flash memory and initialize hardware. It's better to postpone sound card registration. This commit schedules workqueue to process actual probe processing 2 seconds after the last bus-reset. The card instance is kept at unit probe callback and released at card free callback. Therefore, when the actual probe processing fails, the memory block is wasted. This is due to simplify driver implementation. Signed-off-by: Takashi Sakamoto <o-takashi@sakamocchi.jp> Signed-off-by: Takashi Iwai <tiwai@suse.de>

This commit adds a new driver for RME Fireface series. This commit just creates/removes card instance according to IEEE 1394 bus event. More functions will be added in following commits. Three types of firmware have released by RME GmbH; for Fireface 400, for Fireface 800 and for UCX/802/UFX. It's reasonable that these models use different protocol for communication.

2017-03-31ALSA: usb-audio: Fake also USB device id when alias is givenTakashi Iwai1-3/+3
Recently snd-usb-audio driver received a new option, quirk_alias, to allow user to apply the existing quirk for a different device. This works for many quirks as is, but some still need more tune-ups: namely, some quirks check the USB vendor/device IDs in various places, thus it doesn't work as long as the ID is different from the expected one. With this patch, the driver stores the aliased USB ID, so that these rest quirks per device ID are applied. The transition to use the cached USB ID was already done in the past, so what we needed now is only to overwrite chip->usb_id. Signed-off-by: Takashi Iwai <tiwai@suse.de>

2017-03-28ALSA: firewire-motu: add support for MOTU 828mk3 (FireWire/Hybrid) as a ↵Takashi Sakamoto6-1/+345
model with protocol version 3 MOTU 828mk3 (FireWire/Hybrid) is one of third generation in MOTU FireWire series, produced in 2008/2014. This model consists of three chips for functionality on IEEE 1394 bus: * TI TSB41AB2 (Physical layer for IEEE 1394 bus) * Xilinx Spartan-3E FPGA Family (Link layer for IEEE 1394 bus, packet processing and data block processing layer) * TI TMS320C6722 (Digital signal processing) This commit adds a support for this model, with its unique protocol as version 3. This protocol has some additional features to protocol version 2. * Support several optical interfaces. * Support a data chunk for return of reverb effect. * Have a quirk of tx packets. * Support heartbeat asynchronous transaction. In this protocol, series of transferred packets has some quirks. Below fields in CIP headers of the packets are out of IEC 61883-1: - SID (source node id): always 0x0d - DBS (data block size): always 0x04 - DBC (data block counter): always 0x00 - EOH (End of header): always 0x00 Below is an actual sample of transferred packets. quads CIP1 CIP2 520 0x0D040400 0x22FFFFFF 8 0x0D040400 0x22FFFFFF 520 0x0D040400 0x22FFFFFF 520 0x0D040400 0x22FFFFFF 8 0x0D040400 0x22FFFFFF Status of clock is configured by write transactions to 0x'ffff'f000'0b14, as well as version 2, while meanings of fields are different from the former protocols. Modes of optical interfaces are configured by write transactions to 0x'ffff'f000'0c94. Drivers can register its address to receive heatbeat transactions from the unit. 0x'ffff'f000'0b0c is for the higher part and 0x'ffff'f000'0b10 is for the lower part. Nevertheless, this feature is not useless for this driver and this commit omits it. Each data block consists of two parts in a point of the number of included data chunks. In both of 'fixed' and 'differed' parts, the number of included data blocks are a multiple of 4, thus depending on models there's some empty data chunks. For example, 828mk3 includes one pair of empty data chunks in its fixed part. When optical interface is configured to S/PDIF, 828mk3 includes one pair of empty data chunks in its differed part. To reduce consumption of CPU cycles with additional conditions/loops, this commit just exposes these empty chunks to user space as PCM channels. Additionally, 828mk3 has a non-negligible overhead to change its sampling transfer frequency. When softwares send asynchronous transaction to perform it, LED on the unit starts to blink. In a worst case, it continues blink during several seconds; e.g. 10 seconds. When stopping blinking, the unit seems to be prepared for the requested sampling transfer frequency. To wait for the preparation, this commit forces the driver to call task scheduler and applications sleeps for 4 seconds.

version 2 MOTU 828mk2 is one of second generation in MOTU FireWire series, produced in 2003. This model consists of four chips: * TI TSB41AB2 (Physical layer for IEEE 1394 bus) * PDI 1394L40BE (Link layer for IEEE 1394 bus and packet processing layer) * ALTERA ACEX 1K EP1K30 Series FPGA (Data block processing layer) * TI TMS320VC5402 (Digital signal processing) This commit adds a support for this model, with its unique protocol as version 2. The features of this protocol are: * Support data chunks for status and control messages for both directions. * Support a pair of MIDI input/output. * Support a data chunk for mic/instrument independent of analog line in. * Support a data chunk for playback return. * Support independent data chunks for S/PDIF of both optical/coaxial interfaces. * Support independent data chunks for each of main out and phone out. Status of clock is configured by write transactions to 0x'ffff'f000'0b14. Modes of optical interfaces are configured by write transactions to 0x'ffff'f000'0c04.

2017-03-28ALSA: firewire-motu: add MIDI functionalityTakashi Sakamoto6-4/+260
In MOTU FireWire series, MIDI messages are multiplexed to isochronous packets as well as PCM frames, while the way is different from the one in IEC 61883-6. MIDI messages are put into a certain position in message chunks. One data block can includes one byte of the MIDI messages. When data block includes a MIDI byte, the block has a flag in a certain position of the message chunk. These positions are unique depending on protocols. Once a data block includes a MIDI byte, some following data blocks includes no MIDI bytes. Next MIDI byte appears on a data block corresponding to next cycle of physical MIDI bus. This seems to avoid buffer overflow caused by bandwidth differences between IEEE 1394 bus and physical MIDI bus. This commit adds MIDI functionality to transfer/receive MIDI messages.
