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. Signed-off-by:

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. Signed-off-by:

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. However, tracepoints are not supported yet, unlike implementation for IEC 61883-1/6 protocol. This commit adds support of tracepoints for the protocol. Signed-off-by:

In ALSA firewire stack, some AV/C commands are supported, including vendor's extensions. Drivers includes response parser of each command, according to its requirements, while the parser is written with loose fashion in two points; error check and length check. This doesn't cause any issues such as kernel corruption, but should be improved. This commit modifies evaluations of return value on each parsers. Reported-by:

At a commit 9dc5d31c ("ALSA: firewire-digi00x: handle MIDI messages in isochronous packets"), a functionality to handle MIDI messages on isochronous packet was supported. But this includes some of my misunderstanding. This commit is to fix them. For digi00x series, first data channel of data blocks in rx/tx packet includes MIDI messages. The data channel has 0x80 in 8 bit of its MSB, however it's against IEC 61883-6. Unique data format is applied: - Upper 4 bits of LSB represent port number. - 0x0: port 1. - 0x2: port 2. - 0xe: console port. - Lower 4 bits of LSB represent the number of included MIDI message bytes; 0x0/0x1/0x2. - Two bytes of middle of this data channel have MIDI bytes. Especially, MIDI messages from/to console surface are also transferred by isochronous packets, as well as physical MIDI ports. Signed-off-by:

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. Signed-off-by:

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. Signed-off-by:

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. Signed-off-by:

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. This will be described in later commits. Signed-off-by:

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. Signed-off-by:

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. Signed-off-by:

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:

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: -

On this Dell AIO machine, the lineout jack does not work. We found the pin 0x1a is assigned to lineout on this machine, and in the past, we applied ALC298_FIXUP_DELL1_MIC_NO_PRESENCE to fix the heaset-set mic problem for this machine, this fixup will redefine the pin 0x1a to headphone-mic, as a result the lineout doesn't work anymore. After consulting with Dell, they told us this machine doesn't support microphone via headset jack, so we add a new fixup which only defines the pin 0x18 as the headset-mic. [rearranged the fixup insertion position by tiwai in order to make the merge with other branches easier -- tiwai] Fixes: 59ec4b57 ("ALSA: hda - Fix headset mic detection problem for two dell machines") Cc: <stable@vger.kernel.org> Signed-off-by:

Merge tag 'asoc-fix-v4.11-rc4' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound into for-linus ASoC: Fixes for v4.11 A relatively large pile of fixes for mainline, the first since the merge window. The biggest block of changes here by volume is the sun8i-codec set, the driver was newly added in the merge window but it was realized that renaming some of the user visible controls was required so these are being pushed for v4.11 to avoid the original code appearing in a release. Otherwise it's all fairly standard bugfix stuff.
