* ALSA: dice: add support for Solid State Logic Duende Classic/MiniTakashi Sakamoto2019-01-28
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Duende Classic was produced by Solid State Logic in 2006, as a first model of Duende DSP series. The following model, Duende Mini was produced in 2008. They are designed to receive isochronous packets for PCM frames via IEEE 1394 bus, perform signal processing by downloaded program, then transfer isochronous packets for converted PCM frames. These two models includes the same embedded board, consists of several ICs below: - Texus Instruments Inc, TSB41AB3 for physical layer of IEEE 1394 bus - WaveFront semiconductor, DICE II STD ASIC for link/protocol layer - Altera MAX 3000A CPLD for programs - Analog devices, SHARC ADSP-21363 for signal processing (4 chips) This commit adds support for the two models to ALSA dice driver. Like support for the other devices, packet streaming is just available. Userspace applications should be developed if full features became available; e.g. program uploader and parameter controller. $ ./hinawa-config-rom-printer /dev/fw1 { 'bus-info': { 'adj': False, 'bmc': False, 'chip_ID': 349771402425, 'cmc': True, 'cyc_clk_acc': 255, 'generation': 1, 'imc': True, 'isc': True, 'link_spd': 2, 'max_ROM': 1, 'max_rec': 512, 'name': '1394', 'node_vendor_ID': 20674, 'pmc': False}, 'root-directory': [ ['VENDOR', 20674], ['DESCRIPTOR', 'Solid State Logic'], ['MODEL', 112], ['DESCRIPTOR', 'Duende board'], [ 'NODE_CAPABILITIES', { 'addressing': {'64': True, 'fix': True, 'prv': True}, '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}}], [ 'UNIT', [ ['SPECIFIER_ID', 20674], ['VERSION', 1], ['MODEL', 112], ['DESCRIPTOR', 'Duende board']]]]} Signed-off-by: Takashi Sakamoto <o-takashi@sakamocchi.jp> Signed-off-by: Takashi Iwai <tiwai@suse.de>
* ALSA: dice: fix to wait for releases of all ALSA character devicesTakashi Sakamoto2018-10-27
| | | | | | | | | | | | | | In a development period for Linux kernel v4.20, drivers in ALSA firewire stack were changed to wait for releases of all ALSA character devices at .remove callback of bus driver. However, ALSA dice driver is partly out of this change. This bug can bring fault to user process which holds the last of character device in unplugging. This commit fixes the driver to wait in the callback.

* ALSA: firewire: use managed-resource of fw unit device for private dataTakashi Sakamoto2018-10-04
| | | | | | | | | | | | | | | | | 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>
* ALSA: dice: add stream format parameters for TC Electronic Digital Konnekt x32Takashi Sakamoto2018-05-21

For such devices, ALSA dice driver needs to have hard-coded parameters for stream formats. This commit adds stream format parameters for this model. Unfortunately, at sampling transmission frequencies of 88.2/96.0kHz, I confirmed that current ALSA dice driver doesn't drive the device appropriately due to detecting packet discontinuities. $ journalctl kernel: snd_dice fw1.0: Detect discontinuity of CIP: 90 80 At the frequencies, the device transfers 16 data blocks per packet and 16 data channels per data block, as a result one packet includes 1032 bytes if it's not NODATA. However, as long as I checked, the device often postpone packet transmission and continue with truncated payload than metadata in isochronous packet header. Below is a sample of sequence I got. sec cycle bytes CIP1 CIP2 37 3314 1032 0x01100090 0x900449E2 37 3315 8 0x011000A0 0x9004FFFF 37 3316 1032 0x011000A0 0x900461E2 37 3317 1032 0x011000B0 0x900475E2 37 3318 1032 0x011000C0 0x900489E2 37 3319 8 0x011000D0 0x9004FFFF 37 3320 1032 0x011000D0 0x9004A1E2 37 3321 1032 0x011000E0 0x9004B5E2 37 3322 1032 0x011000F0 0x9004C9E2 37 3323 8 0x01100000 0x9004FFFF 37 3324 1032 0x01100000 0x9004E1E2 37 3325 1032 0x01100010 0x9004F5E2 37 3326 1032 0x01100020 0x900409E2 37 3327 8 0x01100030 0x9004FFFF 37 3328 1032 0x01100030 0x900421E2 37 3329 1032 0x01100040 0x900435E2 37 3330 (skip) 37 3331 (skip) 37 3332 (skip) 37 3333 (skip) 37 3334 (skip) 37 3335 (skip) 37 3336 (skip) 37 3337 (skip) 37 3338 (skip) 37 3339 (skip) 37 3340 (skip) 37 3341 (skip) 37 3342 (skip) 37 3343 (skip) 37 3344 (skip) 37 3345 (skip) 37 3346 (skip) 37 3347 (skip) 37 3348 (skip) 37 3349 (skip) 37 3350 (skip) 37 3351 (skip) 37 3352 (skip) 37 3353 (skip) 37 3354 (skip) 37 3355 (skip) 37 3356 (skip) 37 3357 (skip) 37 3358 (skip) 37 3359 (skip) 37 3360 (skip) 37 3361 (skip) 37 3362 (skip) 37 3363 (skip) 37 3364 (skip) 37 3365 (skip) 37 3366 (skip) 37 3367 1032 0x01100050 0x900461E1 37 3368 1032 0x01100060 0x900475E1 37 3369 1032 0x01100070 0x9004A1E1 37 3370 1032 0x01100080 0x9004A1E1 but content of payload is truncated. 37 3371 (skip) 37 3371 1032 0x01100080 0x9004B5E0 detect discontinuity 37 3372 1032 0x01100090 0x9004C9E0 37 3373 1032 0x011000A0 0x9004E1E0 37 3374 1032 0x011000B0 0x9004F5E0 37 3375 1032 0x011000C0 0x900409E0 37 3376 1032 0x011000D0 0x900421E0 37 3377 1032 0x011000E0 0x900435E0 37 3378 1032 0x011000F0 0x900449DF 37 3379 8 0x01100000 0x9004FFFF 37 3380 1032 0x01100000 0x900461DF 37 3381 1032 0x01100010 0x900475DF 37 3382 1032 0x01100020 0x900489DF 37 3383 8 0x01100030 0x9004FFFF 37 3384 1032 0x01100030 0x9004A1DF 37 3385 1032 0x01100040 0x9004B5DF 37 3386 1032 0x01100050 0x9004C9DF 37 3387 8 0x01100060 0x9004FFFF I cannot confirm this quirks with Windows driver. ALSA dice driver has a cause if assumed differences between these two drivers are ways of timestampling to RX packets from the drivers to the device. I've already reported timestamping quirk of Dice-based devices and this might bring this issue. [alsa-devel] Dice packet sequence quirk and ALSA firewire stack in Linux 4.6 http://mailman.alsa-project.org/pipermail/alsa-devel/2016-May/107715.html Well, nevertheless, I enable ALSA dice driver to work at the frequencies.

* ALSA: dice: remove local frag of force_two_pcmsTakashi Sakamoto2018-05-02
| | | | | | | | | | | | | | | | | | | | | | At present, to add PCM substreams for each of available tx/rx streams, this driver uses a condition based on model-name. This is not enough to support unknown models. In former commits, this driver gains cache of stream formats. For models which support protocol extension, all of available steam formats are cached. For known models, hard-coded stream formats are used to generate the cache. For unknown models, stream formats at current mode of sampling transmission frequency is cached. Anyway, at least, the cached formats are used to expose constrains of PCM substreams for userspace applications. Thus, The cached data can be also used to add PCM substreams themselves, instead of the name-based conditions. This commit obsoletes local frag of force_two_pcms.

I note that each of pair of iO14/iO26 and MultiMix 8/12/16 has the same model ID on their configuration ROM. The MultiMix 8/12/16 just support one mode for sampling transmission frequency and ALSA dice driver already handles them correctly. The iO14/iO26 support three modes and need hard-coded parameters.

* ALSA: dice: force to add two pcm devices for listed modelsTakashi Sakamoto2016-03-09
| | | | | | | | | | | | | | | | | | | | Some models reduce the number of available isochronous streams for higher sampling transfer frequency. Such models bring an issue about how to add PCM substreams. When at lower sampling transfer frequency, the models reports whole available streams, thus this driver can add enough number of PCM substreams at probing time. On the other hand, at higher sampling transfer frequency, this driver can just add reduced number of PCM substreams. After probed, even if the sampling transfer frequency is changed to lower rate, fewer PCM substreams are actually available. This is inconvenience. For the reason, this commit adds a list so that this driver assume models on the list to have two pairs of PCM substreams. This list keeps the name of model in which the number of available streams differs depending on sampling transfer frequency.

| | | | | | | | | | | | | | | | | | | | | | | | | Dice interface design doesn't allow drivers to read supported combination between sampling transfer frequencies and the number of Multi bit linear audio data channels. Due to the design, ALSA dice driver changes current sampling transfer frequency to generate cache of the combinations at device probing processing. Although, this idea is worse because ALSA dice driver changes the state of clock. This is not what users want when they save favorite configuration to the device in advance. Furthermore, there's a possibility that the format of data block is decided not only according to current sampling transfer frequency, but also the other factors, i.e. data format for digital interface. It's not good to generate channel cache according to the sampling transfer frequency only. This commit purges processing cache data and related structure members. As a result, users must set preferable sampling transfer frequency before using ALSA PCM applications, as long as they want to start any PCM substreams at the rate except for current one.

* ALSA: dice: postpone card registrationTakashi Sakamoto2016-01-06
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some models based on ASIC for Dice II series (STD, CP) change their hardware configurations after appearing on IEEE 1394 bus. This is due to interactions of boot loader (RedBoot), firmwares (eCos) and vendor's configurations. This causes current ALSA dice driver to get wrong information about the hardware's capability because its probe function runs just after detecting unit of the model. As long as I investigated, it takes a bit time (less than 1 second) to load the firmware after bootstrap. Just after loaded, the driver can get information about the unit. Then the hardware is initialized according to vendor's configurations. After, the got information becomes wrong. Between bootstrap, firmware loading and post configuration, some bus resets are observed. This commit offloads most processing of probe function into workqueue and schedules the workqueue after successive bus resets. This has an effect to get correct hardware information and avoid involvement to bus reset storm. For code simplicity, this change effects all of Dice-based models, i.e. Dice II, Dice Jr., Dice Mini and Dice III. I use a loose strategy to manage a race condition between the work and the bus reset. This is due to a specification of dice transaction. When bus reset occurs, registered address for the transaction is cleared. Drivers must re-register their own address again. While, this operation is required for the work because the work includes to wait for the transaction. This commit uses no lock primitives for the race condition. Instead, checking 'registered' member of 'struct snd_dice' avoid executing the work again. If sound card is not registered, the work can be scheduled again by bus reset handler. When .remove callback is executed, the sound card is going to be released. The work should not be pending or executed in the releasing. This commit uses cancel_delayed_work_sync() in .remove callback and wait till the pending work finished. After .remove callback, .update callback is not executed, therefore no works are scheduled again. Signed-off-by: Takashi Sakamoto <o-takashi@sakamocchi.jp> Signed-off-by: Takashi Iwai <tiwai@suse.de>
* ALSA: dice: split subaddress check from category checkTakashi Sakamoto2016-01-06
| | | | | | | | | | | | | | Before allocating an instance of sound card, ALSA dice driver checks chip_ID_hi in Bus information block of Config ROM, then also checks subaddresses. The former operation reads cache of Config ROM in Linux FireWire subsystem, while the latter operation sends read transaction. The latter can be merged into initialization of transaction system. This commit splits these two operations to reduce needless transactions in probe processing. Signed-off-by: Takashi Sakamoto <o-takashi@sakamocchi.jp> Signed-off-by: Takashi Iwai <tiwai@suse.de>
* ALSA: dice: fix detection of Loud devicesTakashi Sakamoto2015-11-14
| | | | | | | | | | | | | | | | | Commit a471fcde8c2c ("ALSA: dice: fix detection of Weiss devices") adds a quirk of Weiss models. According to users' reports, Loud models also have the similar quirk. They have 0x10 in the category field. This commit adds support for Mackie Onyx Blackbird and Onyx-i series. As long as I know, Dice-based models produced by Focusrite/Alesis/PreSonus/M-Audio/TC Electronic have default value (0x04) in their category field, thus it may be reasonable to add a condition statement for Loud models, instead of removing the check of category value.

* ALSA: fireworks/bebob/dice/oxfw: add reference-counting for FireWire unitTakashi Sakamoto2015-02-23
| | | | | | | | | | | | | | | | | Fireworks and Dice drivers try to touch instances of FireWire unit after sound card object is released, while references to the unit is decremented in .remove(). When unplugging during streaming, sound card object is released after .remove(), thus Fireworks and Dice drivers causes GPF or Null-pointer-dereferencing to application processes because an instance of FireWire unit was already released. This commit adds reference-counting for FireWire unit in drivers to allow them to touch an instance of FireWire unit after .remove(). In most case, any operations after .remove() may be failed safely.

* ALSA: dice: Add support for duplex streams with synchronizationTakashi Sakamoto2014-12-10
| | | | | | | | | | | | | | | | | | | | | | | | | | This commit adds support for AMDTP in-stream. As a result, Dice driver supports full duplex streams with synchronization. AMDTP can transfer timestamps in its packets. By handling the timestamp, devices can synchronize to the other devices or drivers on the same bus. When Dice chipset is 'enabled', it starts streams with correct settings. This 'enable' register is global, thus, when a stream is started to run, an opposite stream can't start unless turning off 'enable'. Therefore a pair of streams must be running. This causes a loss of CPU usage when single stream is needed for neither playbacking or capturing. This commit assumes that playback-only models also have a functionality to transmit stream for delivering timestamps. Currently, sampling clock source is restricted to SYT-Match mode. This is improved in followed commit. I note that at SYT-Match mode, Dice can select from 4 streams for synchronization but this driver uses the 1st stream only for simplicity.

* ALSA: dice: Split stream functionality into a fileTakashi Sakamoto2014-11-29
| | | | | | | | | | | | | | | | | | | | | This commit adds a file with some helper functions for streaming, and move some codes into the file with some arrangements. Well-known CMP is not used to start/stop streams for Dice chipset. It's achieved by writing to specific address. We call this way as 'enable'. When devices are 'enabled', streaming starts in registered isochronous channel. Some helper functions are already implemented in previous commit. Basically, the stream is compliant to IEC 61883-6, so-called as AMDTP. But Dice has a specific quirk, so called-as 'Dual Wire'. This quirk is applied at 176.4/192.0kHz. In this mode, each packet includes double number of events than number in the specification, and stream runs at a half of sampling rate. There is another quirk at bus reset. Dice chipset handles drivers' request but don't re-enable streaming. So stream should be stopped. Signed-off-by: Takashi Sakamoto <o-takashi@sakamocchi.jp> Signed-off-by: Takashi Iwai <tiwai@suse.de>
* ALSA: dice: Split transaction functionality into a fileTakashi Sakamoto2014-11-29
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This commit adds a file with some helper functions for transaction, and move some codes into the file with some arrangements. For Dice chipset, well-known FCP or AV/C commands are not used to control devices. It's achieved by read/write transactions into specific addresses. Dice's address area is split into 5 areas. Each area has its own role. The offset for each area can be got by reading head of the address area. By reading these areas, drivers can get to know device status. By writing these areas, drivers can change device status. Dice has a specific mechanism called as 'notification'. When device status is changed, Dice devices tells the event by sending transaction. This notification is sent to an address which drivers register in advance. But this causes an issue to drivers. To handle the notification, drivers need to allocate its own callback function to the address region in host controller. This region is exclusive. For the other applications, drivers must give a mechanism to read the received notification. For this purpose, Dice driver already implements hwdep interface. Dice chipset doesn't allow drivers to register several addresses. In this reason, when this driver is applied to a device, the other drivers should _not_ try to register its own address to the device.
