The nodes to restart packet streaming should request reallocation of the resources. However, between the bus-reset and invocation of 'struct fw_driver.update' handler, ALSA PCM application can detect this situation by XRUN because the target device cancelled to transmit packets once bus-reset occurs. Due to the above mechanism, ALSA fireface driver just stops packet streaming in the update handler, thus pcm.prepare handler should request the reallocation. This commit requests the reallocation in pcm.prepare callback when bus generation is changed. Signed-off-by: Takashi Sakamoto <o-takashi@sakamocchi.jp> Signed-off-by: Takashi Iwai <tiwai@suse.de>

This commit separates the allocation and starting. The allocation is done in pcm.hw_params callback and available till pcm.hw_free callback. Even if any XRUN occurs, pcm.prepare callback is done to restart packet streaming for allocated the resources.

| | | | | | | | | | | | | | | | | | | | | | | | | 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>

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.

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.

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>

| | | | | | | | | | | Both of Fireface 400/800 have the same register to switch frame fetching mode regardless of difference of available number of PCM frames in rx isochronous packet. This commit moves a helper function from model-dependent implementation. Signed-off-by: Takashi Sakamoto <o-takashi@sakamocchi.jp> Signed-off-by: Takashi Iwai <tiwai@suse.de>
* ALSA: fireface: fix for state to fetch PCM framesTakashi Sakamoto2018-12-161-1/+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.

* ALSA: fireface: add support for Fireface 800 with MIDI functionality onlyTakashi Sakamoto2018-12-114-13/+69
| | | | | | | | | | | | | | | | | | | | 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.

* ALSA: fireface: add driver data for register for MIDI high addressTakashi Sakamoto2018-12-114-34/+34
| | | | | | | | | | | | | | Fireface 400 and 800 have the same mechanism to decide address to which asynchronous transactions are sent for MIDI messages, however they use different registers for controllers to notify higher 4 byte of the address. This commit adds a model-specific parameter to represent the address. Additionally, it corrects some comments. I note that these two models have a difference to enable/disable the transaction.

| | | | | | | | | | | | As long as investigating packet dumps from Fireface 400/800, a register to receive asynchronous transactions for MIDI messages is the same. For Fireface 800, minor register is used. This commit declares macros for the transactions and obsoletes model-specific parameters.

* ALSA: fireface: add support for second optical interface for ADAT streamTakashi Sakamoto2018-12-113-10/+30
| | | | | | | | | | | | Unlike Fireface 400, Fireface 800 have two pair of optical interface for ADAT signal and S/PDIF signal. ADAT signals for the interface are handled for sampling clock source separately. This commit modifies a parser for clock configuration to distinguish these two ADAT signals.

| | | | | | | | | | | | | | | In an initial commit, 'SYNC_STATUS' register is referred to get clock configuration, however this is wrong, according to my local note at hand for reverse-engineering about packet dump. It should be 'CLOCK_CONFIG' register. Actually, ff400_dump_clock_config() is correctly programmed. This commit fixes the bug.
