fd1cc9de - ALSA: fireface: add support for Fireface UCX

Sun, 20 Jan 2019 08:25:53 +0000

ALSA: fireface: add support for Fireface UCXFireface UFX was shipped by RME GmbH in 2012. This model supports laterprotocol for management of isochronous communication and synchronizationof sampling transmission frequency.This commit adds support for the model. At present, it's not clear howto encode MIDI messages and decide destination address for asynchronoustransaction, thus this commit adds support for isochronous communicationfor PCM frames only.Signed-off-by: Takashi Sakamoto Signed-off-by: Takashi Iwai List of files: /linux-6.15/sound/firewire/fireface/Makefile

Tue, 11 Dec 2018 10:17:35 +0000

ALSA: fireface: add support for Fireface 800 with MIDI functionality onlyFireface 800 is a flagship model of RME GmbH for audio and music unitson 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 XC9572XLThis commit adds support Fireface 800. In this time, the support isrestricted to its MIDI functionality, thus this commit adds somecondition statements to avoid touching streaming functionality.Unlike Fireface 400, Fireface 800 has no functionality to suppressasynchronous transactions for MIDI messages except for unregister oflisten address in controller side, thus the feature is available as is.Signed-off-by: Takashi Sakamoto Signed-off-by: Takashi Iwai List of files: /linux-6.15/sound/firewire/fireface/Makefile

4b316436 - ALSA: fireface: add support for PCM functionality

Fri, 31 Mar 2017 13:06:10 +0000

ALSA: fireface: add support for PCM functionalityThis commit adds PCM functionality to transmit/receive PCM frames onisochronous packet streaming. This commit enables userspace applicationsto start/stop packet streaming via ALSA PCM interface.Sampling rate requested by applications is used as sampling transmissionfrequency of IEC 61883-1/6packet streaming. As I described in followedcommits, units in this series manages sampling clock frequencyindependently of sampling transmission frequency, and they supportsresampling between their packet streaming/data block processing layer andsampling data processing layer. This commit take this driver to utilizethese features for usability.When internal clock is selected as source signal of sampling clock, thisdriver allows user space applications to start PCM substreams at any ratewhich packet streaming engine supports as sampling transmission frequency.In this case, this driver expects units to perform resampling PCM framesfor rx/tx packets when sampling clock frequency and sampling transmissionfrequency are mismatched. This is for daily use cases.When any external clock is selected as the source signal, this drivergets configured sampling rate from units, then restricts availablesampling rate to the rate for PCM applications. This is for studio usecases.Models in this series supports 64.0/128.0 kHz of sampling rate, howeverthese frequencies are not supported by IEC 61883-6 as sampling transmissionfrequency. Therefore, packet streaming engine of ALSA firewire stack can'thandle them. When units are configured to use any external clock as sourcesignal of sampling clock and one of these unsupported rate is configuredas rate of the sampling clock, this driver returns EIO to user spaceapplications.Anyway, this driver doesn't voluntarily configure parameters of samplingclock. It's better for users to work with appropriate user spaceimplementations to configure the parameters in advance of usage.Signed-off-by: Takashi Sakamoto Signed-off-by: Takashi Iwai List of files: /linux-6.15/sound/firewire/fireface/Makefile

75d6d898 - ALSA: fireface: add stream management functionality

Fri, 31 Mar 2017 13:06:09 +0000

ALSA: fireface: add stream management functionalityThis commit adds management functionality for packet streaming.As long as investigating Fireface 400, there're three modes dependingon sampling transmission frequency. The number of data channels in eachdata block is different depending on the mode. The set of availabledata channels for each mode might be different for each protocol andmodel.The length of registers for the number of isochronous channel is justthree bits, therefore 0-7ch are available.When bus reset occurs on IEEE 1394 bus, the device discontinues totransmit packets. This commit aborts PCM substreams at bus reset handler.As I described in followed commits, The device manages its sampling clockindependently 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 bufferfor resampling. As a result, device latency might tend to be larger thanASICs for IEC 61883-1/6 such as DM1000/DM1100/DM1500 (BeBoB),DiceII/TCD2210/TCD2220/TCD3070 and OXFW970/971.Signed-off-by: Takashi Sakamoto Signed-off-by: Takashi Iwai List of files: /linux-6.15/sound/firewire/fireface/Makefile

6fb7db90 - ALSA: fireface: add unique data processing layer

Fri, 31 Mar 2017 13:06:08 +0000

ALSA: fireface: add unique data processing layerAs long as investigating Fireface 400, format of payload of eachisochronous packet is not IEC 61883-1/6, thus its format of data blockis 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 anddifferent way to check packet discontinuity. For tx packet, the ancillaryfield is used for counter. However, the way of counting is differentdepending 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 asSYT_INTERVAL. There's no empty packet or no-data packet, thus thethroughput is not 8,000 packets per sec. On the other hand, the one inrx packet is 8,000 packets per sec, thus the number of data blocks isdifferent between each packet, depending on sampling transmissionfrequency: * 44.1 kHz: 5 or 6 * 48.0 kHz: 5 or 6 or 7 * 88.2 kHz: 10 or 11 or 12This commit adds data processing layer to satisfy the above specificationin a policy of 'best effort'. Although PCM frames are handled forintermediate buffer to user space, the ancillary data is not handled at allto reduce CPU usage, thus counter is not checked. 0 is always used for tagof isochronous packet. Furthermore, the packet streaming layer isresponsible 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: Takashi Sakamoto Signed-off-by: Takashi Iwai List of files: /linux-6.15/sound/firewire/fireface/Makefile

19174295 - ALSA: fireface: add transaction support

Fri, 31 Mar 2017 13:06:03 +0000

ALSA: fireface: add transaction supportAs long as investigating Fireface 400, MIDI messages are transferred byasynchronous 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 toMIDI port 1 and 2.Fireface 400 transfers MIDI messages by write transactions to certainaddresses which configured by drivers. The drivers can decide upper 4 byteof the addresses by write transactions to 0x'0000'0801'03f4. For the restpart of the address, drivers can select from below options: * 0x'0000'0000 * 0x'0000'0080 * 0x'0000'0100 * 0x'0000'0180Selected options are represented in register 0x'0000'0801'051c as bitflags. Due to this mechanism, drivers are restricted to use addresses on'Memory space' of IEEE 1222, even if transactions to the address havesome side effects.This commit adds transaction support for MIDI messaging, based on myassumption that the similar mechanism is used on the other protocols. Toreceive asynchronous transactions, the driver allocates a range of addressin 'Memory space'. I apply a strategy to use 0x'0000'0000 as lower 4 byteof the address. When getting failure from Linux FireWire subsystem, thisdriver retries to allocate addresses.Unfortunately, read transaction to address 0x'0000'0801'051c returns zeroalways, however write transactions have effects to the other features suchas status of sampling clock. For this reason, this commit delegates a taskto configure this register to user space applications. The applicationsshould set 3rd bit in LSB in little endian order.Signed-off-by: Takashi Sakamoto Signed-off-by: Takashi Iwai List of files: /linux-6.15/sound/firewire/fireface/Makefile
