* ALSA: firewire: use 'GPL' string for module license contributed by Takashi ↵Takashi Sakamoto2023-06-121-1/+1
| | | | | | | | | | | | | | Sakamoto In MODULE_LICENSE macro, "GPL" string obsoletes "GPL v2" string by a commit bf7fbeeae6db ("module: Cure the MODULE_LICENSE "GPL" vs. "GPL v2" bogosity"). This commit uses the preferable expression.

* ALSA: bebob: correct duplicated entries with TerraTec OUITakashi Sakamoto2021-07-051-3/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | ALSA bebob driver has duplicated entries for modalias of 'ieee1394:ven00000AACmo00000002sp0000A02Dver00010001' since entries for two devices below have the same parameters: * Acoustic Reality eAR Master One, Eroica, Figaro, and Ciaccona * TerraTec Aureon 7.1 FireWire I relied on FFADO revision 737 to add the former entry, on the other hand, the latter is based on message posted by actual user with information of sysfs node: * https://sourceforge.net/p/ffado/mailman/ffado-user/thread/5743F969.2080204%40marcobaldo.ch/ It appears that they have OUI of Terratec Electronic GmbH (0x000aac) and the same model ID, thus suffice to say that they have something common in their internals. Although it's not going to make a big difference, this commit arranges the entries.

* ALSA: bebob: add support for ToneWeal FW66Takashi Sakamoto2021-06-201-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | A user of FFADO project reported the issue of ToneWeal FW66. As a result, the device is identified as one of applications of BeBoB solution. I note that in the report the device returns contradictory result in plug discovery process for audio subunit. Fortunately ALSA BeBoB driver doesn't perform it thus it's likely to handle the device without issues. I receive no reaction to test request for this patch yet, however it would be worth to add support for it. daniel@gibbonmoon:/sys/bus/firewire/devices/fw1$ grep -r . * Binary file config_rom matches dev:244:1 guid:0x0023270002000000 hardware_version:0x000002 is_local:0 model:0x020002 model_name:FW66 power/runtime_active_time:0 power/runtime_active_kids:0 power/runtime_usage:0 power/runtime_status:unsupported power/async:disabled power/runtime_suspended_time:0 power/runtime_enabled:disabled power/control:auto subsystem/drivers_autoprobe:1 uevent:MAJOR=244 uevent:MINOR=1 uevent:DEVNAME=fw1 units:0x00a02d:0x010001 vendor:0x002327 vendor_name:ToneWeal fw1.0/uevent:MODALIAS=ieee1394:ven00002327mo00020002sp0000A02Dver00010001 fw1.0/power/runtime_active_time:0 fw1.0/power/runtime_active_kids:0 fw1.0/power/runtime_usage:0 fw1.0/power/runtime_status:unsupported fw1.0/power/async:disabled fw1.0/power/runtime_suspended_time:0 fw1.0/power/runtime_enabled:disabled fw1.0/power/control:auto fw1.0/model:0x020002 fw1.0/rom_index:15 fw1.0/specifier_id:0x00a02d fw1.0/model_name:FW66 fw1.0/version:0x010001 fw1.0/modalias:ieee1394:ven00002327mo00020002sp0000A02Dver00010001 Cc: Daniel Jozsef <daniel.jozsef@gmail.com> Reference: https://lore.kernel.org/alsa-devel/20200119164335.GA11974@workstation/ Signed-off-by: Takashi Sakamoto <o-takashi@sakamocchi.jp> Link: https://lore.kernel.org/r/20210619083922.16060-1-o-takashi@sakamocchi.jp Signed-off-by: Takashi Iwai <tiwai@suse.de>

* ALSA: bebob: correct device entry for Mackie D.2 FireWire option cardTakashi Sakamoto2021-06-121-4/+3
| | | | | | | | | | | | | | | | | | | | | | | | For Mackie D.2 FireWire option card, 0x00000f is used for the value of immediate entry for vendor in unit directory. The value comes from report by FFADO user in below page: * http://subversion.ffado.org/wiki/AvcModels/MackieD.2. However, it seems to be wrong. There are two causes; vendor's mistake to decide value for GUID field in configuration ROM against standard, as Stefan Richter mentioned in below post: * https://lore.kernel.org/alsa-devel/1443917823-13516-1-git-send-email-o-takashi@sakamocchi.jp/#t Another is implementation of libffado. The library doesn't print out the value from immediate entry for vendor in unit directory. It just print out the first 6 bytes of GUID as vendor ID. This commit replaces with correct vendor OUI.

* ALSA: bebob: distinguish M-Audio ProFire Lightbridge quirkTakashi Sakamoto2021-05-251-1/+9
| | | | | | | | | | | | | | | | | | | In former commit, ALSA IEC 61883-1/6 packet streaming engine drops initial tx packets till the packet includes any event. This allows ALSA bebob driver not to give option to skip initial packet since the engine does drop the initial packet. However, M-Audio ProFire Lightbridge has a quirk to stop packet transmission after start multiplexing event to the packet. After several thousands cycles, it restart packet transmission again. This commit specializes the usage of initial skip option for the model. Additionally, this commit expands timeout enough to wait processing content of tx packet.

* Revert "ALSA: bebob/oxfw: fix Kconfig entry for Mackie d.2 Pro"Takashi Sakamoto2021-05-181-1/+1
| | | | | | | | | | | | | | | | This reverts commit 0edabdfe89581669609eaac5f6a8d0ae6fe95e7f. I've explained that optional FireWire card for d.2 is also built-in to d.2 Pro, however it's wrong. The optional card uses DM1000 ASIC and has 'Mackie DJ Mixer' in its model name of configuration ROM. On the other hand, built-in FireWire card for d.2 Pro and d.4 Pro uses OXFW971 ASIC and has 'd.Pro' in its model name according to manuals and user experiences. The former card is not the card for d.2 Pro. They are similar in appearance but different internally.

* ALSA: bebob/oxfw: fix Kconfig entry for Mackie d.2 ProTakashi Sakamoto2021-05-141-1/+1
| | | | | | | | | | | | | | | | | | | Mackie d.2 has an extension card for IEEE 1394 communication, which uses BridgeCo DM1000 ASIC. On the other hand, Mackie d.4 Pro has built-in function for IEEE 1394 communication by Oxford Semiconductor OXFW971, according to schematic diagram available in Mackie website. Although I misunderstood that Mackie d.2 Pro would be also a model with OXFW971, it's wrong. Mackie d.2 Pro is a model which includes the extension card as factory settings.

This unit uses DM1500 ASIC produced ArchWave AG (formerly known as BridgeCo AG). I note that this model supports three modes in the number of data channels in tx/rx streams; 8 ch pairs, 10 ch pairs, 18 ch pairs. The mode is switched by Vendor-dependent AV/C command, like: $ cd linux-firewire-utils $ ./firewire-request /dev/fw1 fcp 0x00ff000003dbeb0600000000 (8ch pairs) $ ./firewire-request /dev/fw1 fcp 0x00ff000003dbeb0601000000 (10ch pairs) $ ./firewire-request /dev/fw1 fcp 0x00ff000003dbeb0602000000 (18ch pairs) When switching between different mode, the unit disappears from IEEE 1394 bus, then appears on the bus with different combination of stream formats. In a mode of 18 ch pairs, available sampling rate is up to 96.0 kHz, else up to 192.0 kHz. $ ./hinawa-config-rom-printer /dev/fw1 { 'bus-info': { 'adj': False, 'bmc': True, 'chip_ID': 21474898341, 'cmc': True, 'cyc_clk_acc': 100, 'generation': 2, 'imc': True, 'isc': True, 'link_spd': 2, 'max_ROM': 1, 'max_rec': 512, 'name': '1394', 'node_vendor_ID': 987, 'pmc': False}, 'root-directory': [ ['HARDWARE_VERSION', 19], [ 'NODE_CAPABILITIES', { 'addressing': {'64': True, 'fix': True, 'prv': False}, 'misc': {'int': False, 'ms': False, 'spt': True}, 'state': { 'atn': False, 'ded': False, 'drq': True, 'elo': False, 'init': False, 'lst': True, 'off': False}, 'testing': {'bas': False, 'ext': False}}], ['VENDOR', 987], ['DESCRIPTOR', 'Apogee Electronics'], ['MODEL', 126702], ['DESCRIPTOR', 'Ensemble'], ['VERSION', 5297], [ 'UNIT', [ ['SPECIFIER_ID', 41005], ['VERSION', 65537], ['MODEL', 126702], ['DESCRIPTOR', 'Ensemble']]], [ 'DEPENDENT_INFO', [ ['SPECIFIER_ID', 2037], ['VERSION', 1], [(58, 'IMMEDIATE'), 16777159], [(59, 'IMMEDIATE'), 1048576], [(60, 'IMMEDIATE'), 16777159], [(61, 'IMMEDIATE'), 6291456]]]]} Signed-off-by: Takashi Sakamoto <o-takashi@sakamocchi.jp> Signed-off-by: Takashi Iwai <tiwai@suse.de>

| | | | | | | | | | | | | | | | | | | | character devices are released At present, in .remove callback of bus driver just decrease reference count of device for ALSA card instance. This delegates release of the device to a process in which the last of ALSA character device is released. On the other hand, the other drivers such as for devices on PCIe are programmed to block .remove callback of bus driver till all of ALSA character devices are released. For consistency of behaviour for whole drivers, this probably confuses users. This commit takes drivers in ALSA firewire stack to imitate the above behaviour.

| | | | | | | | | | | | | | | | | At present, private data of each driver in ALSA firewire stack is allocated/freed by kernel slab allocator for corresponding unit on IEEE 1394 bus. In this case, resource-managed slab allocator is available to release memory object automatically just before releasing device structure for the unit. This idea can prevent runtime from memory leak due to programming mistakes. This commit uses the allocator for the private data. These drivers already use reference counter to maintain lifetime of device structure for the unit by a pair of fw_unit_get()/fw_unit_put(). The private data is safely released in a callback of 'struct snd_card.private_free(). Signed-off-by: Takashi Sakamoto <o-takashi@sakamocchi.jp> Signed-off-by: Takashi Iwai <tiwai@suse.de>

However the unit has two states relevant to loaded firmware. Initial firmware returns 'FW Audiophile Bootloader', while functional firmware returns 'FW Audiophile'. ALSA bebob driver compares the units' model name to strings of 24 characters by the first 15 characters. This is shorter way to differentiate these two states but confusing to readers. This commit improves the code for this point. Kernel stack is consumed more in call of check_audiophile_booted() by a bit.

* ALSA: bebob: simplify bus-reset handlingTakashi Sakamoto2016-02-201-4/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | At bus-reset, DM1000/DM1100/DM1500 chipsets transfer packets with discontinuous value in 'dbc' field of CIP header. In this case, packet streaming layer in firewire-lib module stops streaming and set XRUN to PCM substream. In ALSA, PCM applications are notified the XRUN status by the return value of ALSA PCM interface. They can recover this state by executing snd_pcm_prepare(), then PCM drivers' prepare handler is called, and start new PCM substream. For ALSA BeBoB driver, the handler establishes new connections and start new AMDTP streaming. Unfortunately, neither the PCM applications nor the driver know the reason of XRUN. The driver gets to know the reason when update handler is called by IEEE 1394 bus driver. As long as I tested, the order of below events are not fixed: * Detecting packet discontinuity in tasklet context of OHCI 1394 driver * Calling prepare handler in process context of ALSA PCM application * Calling update handler in kthread context of IEEE 1394 bus driver The unpredictable order is disadvantage for the driver to be compliant to CMP. In IEC 61883-1, new CMP establish operations should be done 1 sec (isoc_resource_delay) after bus-reset. Within 1 sec, CMP restore operations are allowed. For this reason, in former commit ('b6bc812327aa: ALSA: bebob/firewire-lib: Add a quirk for discontinuity at bus reset'), the process context is forced to wait for executing update handler. The process context wait for bus-reset up to 1 sec. This commit solves the issue, while causes more disadvantages. For PCM applications, calling snd_pcm_prepare() for recovering XRUN state takes more time and the driver got a bit complicated code, while the recovery is not always successful. As long as I tested, DM1000/DM1100/DM1500 and BeBoB firmware can allow drivers to establish new connections just after bus reset. Furthermore, any FCP transactions are handled correctly. Therefore, the driver don't need to wait for bus reset handler for starting new streaming. This commit removes the codes to reduce maintenance cost.

* ALSA: bebob: Send a cue to load firmware for M-Audio Firewire seriesTakashi Sakamoto2014-05-261-9/+14
| | | | | | | | | | | | | | | Just powering on, these devices below wait to download firmware. - Firewire Audiophile - Firewire 410 - Firewire 1814 - ProjectMix I/O But firmware version 5058 or later, flash memory in the device stores the firmware. So this driver can enable these devices by sending a certain cue to load the firmware. Signed-off-by: Takashi Sakamoto <o-takashi@sakamocchi.jp> Signed-off-by: Takashi Iwai <tiwai@suse.de>
* ALSA: bebob: Add support for M-Audio special Firewire seriesTakashi Sakamoto2014-05-261-1/+18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | This commit allows this driver to support some models which M-Audio produces with DM1000 but its firmware is special. They are: - Firewire 1814 - ProjectMix I/O They have heavily customized firmware. The usual operations can't be applied to them. For this reason, this commit adds a model specific member to 'struct snd_bebob' and some model specific functions. Some parameters are write-only so this commit also adds control interface for applications to set them. M-Audio special firmware quirks: - Just after powering on, they wait to download firmware. This state is changed when receiving cue. Then bus reset is generated and the device is recognized as a different model with the uploaded firmware. - They don't respond against BridgeCo AV/C extension commands. So drivers can't get their stream formations and so on. - They do not start to transmit packets only by establishing connection but also by receiving SIGNAL FORMAT command. - After booting up, they often fail to send response against driver's request due to mismatch of gap_count. This module don't support to upload firmware.

* ALSA: bebob: Add support for M-Audio usual Firewire seriesTakashi Sakamoto2014-05-261-2/+43
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This commit allows this driver to support some models which M-Audio produces with DM1000/DM1000E with usual firmware. They are: - Firewire 410 - Firewire AudioPhile - Firewire Solo - Ozonic - NRV10 - FirewireLightBridge According to a person who worked in BridgeCo, some models are produced with 'Pre-BeBoB'. This means that these products were released before BeBoB was officially produced, and later BeBoB specification was formed. So these models have some quirks. M-Audio usual firmware quirks: - Just after powering on, 'Firewire 410' waits to download firmware. This state is changed when receiving cue. Then bus reset is generated and the device is recognized as a different model with the uploaded firmware. - 'Firewire Audiophile' also waits to download firmware but its vendor id/model id is the same as the one after loading firmware. - The information of channel mapping for MIDI conformant data channel is invalid against BridgeCo specification. This commit adds some codes for these quirks but don't support to upload firmware. This commit also adds specific operations to get metering information. The metering information also includes status of clock synchronization if the model supports to switch source of clock. The specification of FirewireLightBridge is unknown. So in this time, normal operations are applied for this model. Signed-off-by: Takashi Sakamoto <o-takashi@sakamocchi.jp> Signed-off-by: Takashi Iwai <tiwai@suse.de>
* ALSA: bebob: Add support for Focusrite Saffire/SaffirePro seriesTakashi Sakamoto2014-05-261-1/+29
| | | | | | | | | | | | | | | | | | | | This commit allows this driver to support all of models which Focusrite produces with DM1000/BeBoB. They are: - Saffire - Saffire LE - SaffirePro 10 I/O - SaffirePro 26 I/O This commit adds Focusrite specific operations: 1. Get source of clock 2. Get/Set sampling frequency 3. Get metering information The driver uses these functionalities to read/write specific address by async transaction.

* ALSA: bebob: Add support for Yamaha GO seriesTakashi Sakamoto2014-05-261-0/+5
| | | | | | | | | | | | | | | | | This commit allows this driver to support all of models which Yamaha produced with DM1000/BeBoB. They are: - GO44 - GO46 This commit adds Yamaha specific operations. To get source of clock, AV/C Audio Subunit command is used. I note that their appearances are similar to some models of TerraTec; 'Go44' is similar to 'PHASE 24 FW' and 'GO46' is similar to 'PHASE X24 FW'. But their combination of Audio/Music subunits is a bit different. Signed-off-by: Takashi Sakamoto <o-takashi@sakamocchi.jp> Signed-off-by: Takashi Iwai <tiwai@suse.de>
