2019-12-11ALSA: firewire: Drop superfluous ioctl PCM opsTakashi Iwai1-2/+0
All the PCM ioctl ops of ALSA FireWire drivers do nothing but calling the default handler. Now PCM core accepts NULL as the default ioctl ops(*), so let's drop altogether.

2019-10-19ALSA: firewire-lib: postpone to start IR contextTakashi Sakamoto1-1/+1
Some devices have a quirk to postpone transmission of isoc packet for several dozen or hundred isoc cycles since configured to transmit. Furthermore, some devices have a quirk to transmit isoc packet with discontinued data of its header. In 1394 OHCI specification, software allows to start isoc context with certain isoc cycle. Linux firewire subsystem has kernel API to use it as well. This commit uses the functionality of 1394 OHCI controller to handle the quirks. At present, this feature is convenient to ALSA bebob and fireface driver.

This commit allows ALSA firewire-motu driver to share PCM buffer size for both capture and playback PCM substream. When AMDTP domain starts for one of the PCM substream, buffer size of the PCM substream is stores to AMDTP domain structure. Some AMDTP streams have already run with the buffer size when another PCM substream starts, therefore the PCM substream has a constraint to its buffer size.

2019-10-18ALSA: firewire-lib: use variable size of queue for isoc packets instead of fixed sizeTakashi Sakamoto1-1/+1
The number of packets in packet buffer has been fixed number (=48) since first commit of ALSA IEC 61883-1/6 packet streaming engine. This commit allows the engine to use variable number of packets in the buffer. The size is calculated by a parameter in AMDTP domain structure surely to store the number of events in the packets of buffer. Although the value of parameter is expected to come from 'period size' parameter of PCM substream, at present 48 is still used.

2019-10-17ALSA: firewire-motu: use the same size of period for PCM substream in AMDTP streamsTakashi Sakamoto1-8/+21
In current implementation, when opening a PCM substream, it's needed to check whether the opposite PCM substream runs. This is to assign effectual constraints (e.g. sampling rate) to opened PCM substream. The number of PCM substreams and MIDI substreams on AMDTP streams in domain is recorded in own structure. Usage of this count is an alternative of the above check. This is better because the count is incremented in pcm.hw_params earlier than pcm.trigger. This idea has one issue because it's incremented for MIDI substreams as well. In current implementation, for a case that any MIDI substream run and a PCM substream is going to start, PCM application to start the PCM substream can decide hardware parameters by restart packet streaming. Just checking the substream count can brings regression. Now AMDTP domain structure has a member for the size of PCM period in PCM substream which starts AMDTP streams in domain. When the value has zero and the substream count is greater than 1, it means that any MIDI substream starts AMDTP streams in domain. Usage of the value can resolve the above issue. This commit replaces the check with the substream count and the value for the size of PCM period.

2019-08-30ALSA: firewire-motu: add support for MOTU 4preTakashi Sakamoto1-0/+12
MOTU 4pre was launched in 2012 by MOTU, Inc. This commit allows userspace applications can transmit and receive PCM frames and MIDI messages for this model via ALSA PCM interface and RawMidi/Sequencer interfaces. The device supports MOTU protocol version 3. Unlike the other devices, the device is simply designed. The size of data block is fixed to 10 quadlets during available sampling rates (44.1 - 96.0 kHz). Each data block includes 1 source packet header, 2 data chunks for messages, 8 data chunks for PCM samples and 2 data chunks for padding to quadlet alignment. The device has no MIDI, optical, BNC and AES/EBU interfaces. Like support for the other MOTU devices, the quality of playback sound is not enough good with periodical noise yet. $ python2 crpp < ~/git/am-config-rom/motu/motu-4pre.img ROM header and bus information block ----------------------------------------------------------------- 400 041078cc bus_info_length 4, crc_length 16, crc 30924 404 31333934 bus_name "1394" 408 20ff7000 irmc 0, cmc 0, isc 1, bmc 0, cyc_clk_acc 255, max_rec 7 (256) 40c 0001f200 company_id 0001f2 | 410 000a41c5 device_id 00000a41c5 | EUI-64 0001f200000a41c5 root directory ----------------------------------------------------------------- 414 0004ef04 directory_length 4, crc 61188 418 030001f2 vendor 41c 0c0083c0 node capabilities per IEEE 1394 420 d1000002 --> unit directory at 428 424 8d000005 --> eui-64 leaf at 438 unit directory at 428 ----------------------------------------------------------------- 428 0003ceda directory_length 3, crc 52954 42c 120001f2 specifier id 430 13000045 version 434 17103800 model eui-64 leaf at 438 ----------------------------------------------------------------- 438 0002d248 leaf_length 2, crc 53832 43c 0001f200 company_id 0001f2 | 440 000a41c5 device_id 00000a41c5 | EUI-64 0001f200000a41c5 Signed-off-by: Takashi Sakamoto <o-takashi@sakamocchi.jp> Signed-off-by: Takashi Iwai <tiwai@suse.de>

2019-07-07firewire-motu: fix wrong reference count for stream functionality at error path of rawmidi interfaceTakashi Sakamoto1-0/+2
In IEC 61883-6, several types of sampling data can be multiplexed into payload of common isochronous packet (CIP). For typical audio and music units, PCM samples and MIDI messages are multiplexed into one packet streaming. ALSA firewire-motu driver allows applications of rawmidi interface to start packet streaming for transmission of MIDI messages. However at error path, the reference count of stream functionality is not operated correctly. This can brings a bug that packet streaming is not stopped when all referrers release the count.

2019-06-18ALSA: firewire-motu: update isochronous resources when starting packet streaming after bus-resetTakashi Sakamoto1-0/+11
After bus reset, isochronous resource manager releases all of allocated isochronous resources. The nodes to transfer isochronous packet 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>
2019-06-18ALSA: firewire-motu: reserve/release isochronous resources in pcm.hw_params/hw_free callbacksTakashi Sakamoto4-56/+84
Once allocated, isochronous resources are available for packet streaming, even if the streaming is cancelled. For this reason, current implementation handles allocation of the resources and starting packet streaming at the same time. However, this brings complicated procedure to start packet streaming. 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 without releasing/allocating the resources. There are two points to stop packet streaming; in pcm.hw_params and pcm.prepare callbacks. The former point is a case that packet streaming is already started for any MIDI substream then packet streaming is requested with different sampling transfer frequency for any PCM substream. The latter point is cases of any XRUN or packet queueing error. Signed-off-by: Takashi Sakamoto <o-takashi@sakamocchi.jp> Signed-off-by: Takashi Iwai <tiwai@suse.de>

2019-03-18ALSA: firewire-motu: add support MOTU 8pre FireWireTakashi Sakamoto4-12/+53
This commit adds support for MOTU 8pre FireWire, which was shipped 2007 and nowadays already discontinued. Userspace applications can transmit and receive PCM frames and MIDI messages for this model via ALSA PCM interface and RawMidi/Sequencer interfaces. Like the other models of MOTU FireWire series, this model has many quirks in its CIP. At first, data channels for two pairs of optical interfaces. At lower sampling transmission frequency, i.e. 44.1 and 48.0 kHz, one pair is available for ADAT data, thus 8 data chunks are transferred by CIP. At middle sampling transmission frequency, i.e. 88.2 and 96.0 kHz, two pairs are available to keep 8 chunks for ADAT data, thus CIP still includes 8 data chunks. Apart from data chunks for optical interface, CIP includes fixed number of data chunks. In tx stream, two chunks for status message, eight chunks for samples from analog 1-8 input, two chunks for mix-return. In rx stream, two chunks for control message, two chunks for main 1-2 output, two chunks for phone 1-2 output, two chunks for dummy 1-2. CIP header in tx stream includes quirks for its dbs and dbc fields. The value of dbs field is fixed to 0x13, against its actual size. The value of dbc field is firstly updated to 0x07 from zero, then it's incremented continuously according to actual number of data h blocks. Finally, the model has own bits to disable frame fetch. This commit uses several options to absorb the above quirks. $ python2 crpp < /sys/bus/firewire/devices/fw1/config_rom ROM header and bus information block ----------------------------------------------------------------- 400 0410b57d bus_info_length 4, crc_length 16, crc 46461 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 00083dfb device_id 0000083dfb | EUI-64 0001f20000083dfb 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 0003991c directory_length 3, crc 39196 42c 120001f2 specifier id 430 1300000f version 434 17103800 model eui-64 leaf at 438 ----------------------------------------------------------------- 438 00022681 leaf_length 2, crc 9857 43c 0001f200 company_id 0001f2 | 440 00083dfb device_id 0000083dfb | EUI-64 0001f20000083dfb Signed-off-by: Takashi Sakamoto <o-takashi@sakamocchi.jp> Signed-off-by: Takashi Iwai <tiwai@suse.de>
2019-03-17ALSA: firewire-motu: use 'version' field of unit directory to identify modelTakashi Sakamoto1-10/+10
Current ALSA firewire-motu driver uses the value of 'model' field of unit directory in configuration ROM for modalias for MOTU FireWire models. However, as long as I checked, Pre8 and 828mk3(Hybrid) have the same value for the field (=0x100800). unit | version | model --------------- | --------- | ---------- 828mkII | 0x000003 | 0x101800 Traveler | 0x000009 | 0x107800 Pre8 | 0x00000f | 0x100800 <- 828mk3(FW) | 0x000015 | 0x106800 AudioExpress | 0x000033 | 0x104800 828mk3(Hybrid) | 0x000035 | 0x100800 <- When updating firmware for MOTU 8pre FireWire from v1.0.0 to v1.0.3, I got change of the value from 0x100800 to 0x103800. On the other hand, the value of 'version' field is fixed to 0x00000f. As a quick glance, the higher 12 bits of the value of 'version' field represent firmware version, while the lower 12 bits is unknown. By induction, the value of 'version' field represents actual model. This commit changes modalias to match the value of 'version' field, instead of 'model' field. For degug, long name of added sound card includes hexadecimal value of 'model' field.

2019-02-26ALSA: firewire-motu: fix construction of PCM frame for capture directionTakashi Sakamoto1-1/+3
In data blocks of common isochronous packet for MOTU devices, PCM frames are multiplexed in a shape of '24 bit * 4 Audio Pack', described in IEC 61883-6. The frames are not aligned to quadlet. For capture PCM substream, ALSA firewire-motu driver constructs PCM frames by reading data blocks byte-by-byte. However this operation includes bug for lower byte of the PCM sample. This brings invalid content of the PCM samples. This commit fixes the bug.
