2024-01-29ALSA: firewire-motu: add support for MOTU 896 mk3 FireWire and HybridTakashi Sakamoto3-0/+12
Mark of the Unicorn released 896 mk3 FireWire in 2008 as part of the third generation of its FireWire series. In 2011, 896 mk3 hybrid was released to support USB protocol. It supports sampling transfer frequency up to 192.0 kHz. The packet format differs depending on both of current sampling transfer frequency and the type of signal in optical interfaces. The model supports transmission of PCM frames as well as MIDI messages. The 896 mk3 FireWire consists of below ICs: * Texas Instruments TSB41AB2 * Xilinx Spartan-3A FPGA, XC3S500E * Texas Instruments TMS320C6722 * Microchip (Atmel) AT91SAM SAM7S256 It supports sampling transfer frequency up to 192.0 kHz. The packet format differs depending on both of current sampling transfer frequency and the type of signal in two pairs of optical interfaces. The model supports transmission of PCM frames, while has no port for MIDi messages. The model supports command mechanism to configure internal DSP. Hardware meter information is available in the first 2 chunks of each data block of tx packet. This commit adds support for it. The 896 mk3 FireWire is just tested, but the 896 mk3 Hybrid is not yet. $ config-rom-pretty-printer < motu-896mk3fw.img ROM header and bus information block ----------------------------------------------------------------- 1024 04100ce1 bus_info_length 4, crc_length 16, crc 3297 1028 31333934 bus_name "1394" 1032 20ff7000 irmc 0, cmc 0, isc 1, bmc 0, cyc_clk_acc 255, max_rec 7 (256) 1036 0001f200 company_id 0001f2 | 1040 00093add device_id 0000604893 | EUI-64 0547556791237341 root directory ----------------------------------------------------------------- 1044 0004ef04 directory_length 4, crc 61188 1048 030001f2 vendor 1052 0c0083c0 node capabilities: per IEEE 1394 1056 d1000002 --> unit directory at 1064 1060 8d000005 --> eui-64 leaf at 1080 unit directory at 1064 ----------------------------------------------------------------- 1064 0003998d directory_length 3, crc 39309 1068 120001f2 specifier id 1072 13000017 version 1076 17101800 model eui-64 leaf at 1080 ----------------------------------------------------------------- 1080 0002cc82 leaf_length 2, crc 52354 1084 0001f200 company_id 0001f2 | 1088 00093add device_id 0000604893 | EUI-64 0547556791237341 $ config-rom-pretty-printer < motu-896mk3hybrid.img ROM header and bus information block ----------------------------------------------------------------- 1024 04103cbe bus_info_length 4, crc_length 16, crc 15550 1028 31333934 bus_name "1394" 1032 20ff7000 irmc 0, cmc 0, isc 1, bmc 0, cyc_clk_acc 255, max_rec 7 (256) 1036 0001f200 company_id 0001f2 | 1040 000ae601 device_id 0000714241 | EUI-64 0547556791346689 root directory ----------------------------------------------------------------- 1044 0004ef04 directory_length 4, crc 61188 1048 030001f2 vendor 1052 0c0083c0 node capabilities: per IEEE 1394 1056 d1000002 --> unit directory at 1064 1060 8d000005 --> eui-64 leaf at 1080 unit directory at 1064 ----------------------------------------------------------------- 1064 000394ac directory_length 3, crc 38060 1068 120001f2 specifier id 1072 13000037 version 1076 17102800 model eui-64 leaf at 1080 ----------------------------------------------------------------- 1080 0002cf69 leaf_length 2, crc 53097 1084 0001f200 company_id 0001f2 | 1088 000ae601 device_id 0000714241 | EUI-64 0547556791346689 Signed-off-by: Takashi Sakamoto <o-takashi@sakamocchi.jp> Link: https://lore.kernel.org/r/20240129022711.254383-1-o-takashi@sakamocchi.jp Signed-off-by: Takashi Iwai <tiwai@suse.de>

2023-01-12ALSA: firewire-lib: move parameter for pcm frame multiplier from context ↵Takashi Sakamoto1-1/+1
payload processing layer The current implementation delegates the task to calculate the number of processed PCM frames into the context payload processing layer. It looks good as long as frame calculation is done for a single purpose. Nevertheless, another purpose, the computation of extra delay for the runtime of PCM substream, requires frame calculation, too. This commit refactors the current implementation so that the packet stream processing layer is responsible for the calculation of PCM frame, too. The member is moved to stream structure for multiplier between data block count and PCM frame count.

2021-10-28ALSA: firewire-motu: export meter information to userspace as float valueTakashi Sakamoto1-2/+5
In command DSP models, one meter information consists of 4 bytes for IEEE 764 floating point (binary32). In previous patch, it is exported to userspace as 32 bit storage since the storage is also handled in ALSA firewire-motu driver as well in kernel space in which floating point arithmetic is not preferable. On the other hand, ALSA firewire-motu driver doesn't perform floating point calculation. The driver just gather meter information from isochronous packets and fill structure fields for userspace. In 'header' target of Kbuild, UAPI headers are processed before installed. In this timing, #ifdef macro with __KERNEL__ is removed. This mechanism is useful in the case so that the 32 bit storage can be accessible as u32 type in kernel space and float type in user space. We can see the same usage in ''struct acct_v3' in 'include/uapi/linux/acct.h'. This commit is for the above idea. Additionally, due to message protocol, meter information is filled with 0xffffffff in the end of period but 0xffffffff is invalid as binary32. To avoid confusion in userspace application, the last two elements are left without any assignment.

2021-10-28ALSA: firewire-motu: refine parser for meter information in register DSP modelsTakashi Sakamoto1-5/+9
After further investigation, I realize that the total number of elements in array is not enough to store all of related messages from device. This commit refines meter array and message parser. In terms of channel identifier, register DSP models are classified to two categories: 1. the target of output is selectable 828mk2, 896hd, and Traveler are in the category. They transfer messages with channel identifier between 0x00 and 0x13 for input meters, therefore 20 elements are needed to store. On the other hand, they transfer messages with channel identifier for one pair of output meters. The selection is done by asynchronous write transaction to offset 0x'ffff'f000'0b2c. The table for relationship between written value and available identifiers is below: ============= =============== written value identifier pair ============= =============== 0x00000b00 0x80/0x81 0x00000b01 0x82/0x83 ... ... 0x00000b0b 0x96/0x97 ... ... 0x00000b10 0xa0/0xa1 ... ... 0x00000b3f 0xfe/0xff ... ... greater 0xfe/0xff ============= =============== Actually in the above three models, 0x96/0x97 pair is the maximum. Thus the number of available output meter is 24. 2. all of output is available 8 pre, Ultralite, Audio Express, and 4 pre are in the category. They transfer messages for output meters without any selection. The table for available identifier for each direction is below: ============== ========= ========== model input output ============== ========= ========== 8 pre 0x00-0x0f 0x82-0x8d Ultralite 0x00-0x09 0x82-0x8f Audio Express 0x00-0x09 0x80-0x8d 4 pre 0x00-0x09 0x80-0x8d ============== ========= ========== Some of available identifiers might not be used for actual output meters. Anyway, 24 plus 24 elements accommodate the input/output meters. I note that isochronous packet from V3HD/V4HD deliver no message. Notification by asynchronous transaction to registered address seems to be used for the purpose as well as for change of mixer parameter.

2021-10-15ALSA: firewire-motu: add message parser to gather meter information in ↵Takashi Sakamoto8-7/+184
register DSP model Some of MOTU models allows software to configure their DSP parameters by accessing to their registers. The models multiplex messages for status of DSP into isochronous packet as well as PCM frames. The message includes information of hardware metering, MIDI message, current parameters of DSP. For my convenience, I call them as 'register DSP' model. This patch adds message parser for them to gather hardware meter information.

2021-09-21ALSA: firewire-motu: fix truncated bytes in message tracepointsTakashi Sakamoto1-3/+4
In MOTU protocol v2/v3, first two data chunks across 2nd and 3rd data channels includes message bytes from device. The total size of message is 48 bits per data block. The 'data_block_message' tracepoints event produced by ALSA firewire-motu driver exposes the sequence of messages to userspace in 64 bit storage, however lower 32 bits are actually available since current implementation truncates 16 bits in upper of the message as a result of bit shift operation within 32 bit storage. This commit fixes the bug by perform the bit shift in 64 bit storage.

The features of this protocol are: * no MIDI support. * Rx packets have no data chunks for control and status messages. * Tx packets have 2 data chunks for control and status messages in the end of each data block. The chunks consist of data block counter (4 byte) and message (2 byte). * All of settings are represented in bit flag in one quadlet address (0x'ffff'f000'0b00). * When optical interface is configured as S/PDIF, signals of the interface is multiplexed for packets, instead of signals of coaxial interface. * The internal multiplexer is not configured by software. I note that the device has a quirk to mute output voluntarily during receiving batch of packets in the beginning of packet streaming. The operation to unmute should be done by software enough after the device shifts the state, however it's not deterministic. Furthermore, just after switching rate of sampling clock, the device keeps the state longer. This patch manages to sleep 100 msec before unmute operation, but it may fail to release the mute in the case that the rate is changed. As a workaround, users can restart packet streaming at the same rate, or write to specific register from userspace. $ python3 crpp < /sys/bus/firewire/devices/fw1/config_rom ROM header and bus information block ----------------------------------------------------------------- 400 04105c54 bus_info_length 4, crc_length 16, crc 23636 404 31333934 bus_name "1394" 408 20001000 irmc 0, cmc 0, isc 1, bmc 0, cyc_clk_acc 0, max_rec 1 (4) 40c 0001f200 company_id 0001f2 | 410 00005015 device_id 0000005015 | EUI-64 0001f20000005015 root directory ----------------------------------------------------------------- 414 0004c65c directory_length 4, crc 50780 418 030001f2 vendor 41c 0c0083c0 node capabilities per IEEE 1394 420 8d000006 --> eui-64 leaf at 438 424 d1000001 --> unit directory at 428 unit directory at 428 ----------------------------------------------------------------- 428 00035052 directory_length 3, crc 20562 42c 120001f2 specifier id 430 13000001 version 434 17101800 model eui-64 leaf at 438 ----------------------------------------------------------------- 438 0002eeb6 leaf_length 2, crc 61110 43c 0001f200 company_id 0001f2 | 440 00005015 device_id 0000005015 | EUI-64 0001f20000005015 Signed-off-by: Takashi Sakamoto <o-takashi@sakamocchi.jp> Link: https://lore.kernel.org/r/20210616082847.124688-2-o-takashi@sakamocchi.jp Signed-off-by: Takashi Iwai <tiwai@suse.de>

This commit takes ALSA firewire-motu driver to perform sequence replay for media clock recovery. Unlike the other types of device, the devices in MOTU FireWire series require two levels of sequence replay; the sequence of the number of data blocks per packet and the sequence of source packet header per data block. The former is already cached by ALSA IEC 61883-1/6 packet streaming engine and ready to be replayed. The latter is also cached by ALSA firewire-motu driver itself with a previous patch. This commit takes the driver to replay both of them from the caches.

2021-05-28ALSA: firewire-lib: add replay target to cache sequence of packetTakashi Sakamoto1-1/+1
In design of audio and music unit in IEEE 1394 bus, feedback of effective sampling transfer frequency (STF) is delivered by packets transferred from device. The devices supported by ALSA firewire stack are categorized to three groups regarding to it. * Group 1: * Echo Audio Fireworks board module * Oxford Semiconductor OXFW971 ASIC * Digidesign Digi00x family * Tascam FireWire series * RME Fireface series * Group 2: * BridgeCo. DM1000/DM1100/DM1500 ASICs for BeBoB solution * TC Applied Technologies DICE ASICs * Group 3: * Mark of the Unicord FireWire series In group 1, the effective STF is determined by the sequence of the number of events per packet. In group 2, the sequence of presentation timestamp expressed in syt field of CIP header is interpreted as well. In group 3, the presentation timestamp is expressed in source packet header (SPH) of each data block. I note that some models doesn't take care of effective STF with large internal buffer. It's reasonable to name it as group 0: * Group 0 * Oxford Semiconductor OXFW970 ASIC The effective STF is known to be slightly different from nominal STF for all of devices, and to be different between the devices. Furthermore, the effective STF is known to be shifted for long-period transmission. This makes it hard for software to satisfy the effective STF when processing packets to the device. The effective STF is deterministic as a result of analyzing the batch of packet transferred from the device. For the analysis, caching the sequence of parameter in the packet is required. This commit adds an option so that AMDTP domain structure takes AMDTP stream structure to cache the sequence of parameters in packet transferred from the device. The parameters are offset ticks of syt field against the cycle to receive the packet and the number of data blocks per packet.
