2020-11-24ALSA: firewire: Clean up a locking issue in copy_resp_to_buf()Dan Carpenter1-2/+2
commit 02a9c6ee4183af2e438454c55098b828a96085fb upstream. The spin_lock/unlock_irq() functions cannot be nested. The problem is that presumably we would want the IRQs to be re-enabled on the second call the spin_unlock_irq() but instead it will be enabled at the first call so IRQs will be enabled earlier than expected. In this situation the copy_resp_to_buf() function is only called from one function and it is called with IRQs disabled. We can just use the regular spin_lock/unlock() functions.

2020-09-12ALSA; firewire-tascam: exclude Tascam FE-8 from detectionTakashi Sakamoto1-1/+29
Tascam FE-8 is known to support communication by asynchronous transaction only. The support can be implemented in userspace application and snd-firewire-ctl-services project has the support. However, ALSA firewire-tascam driver is bound to the model. This commit changes device entries so that the model is excluded. In a commit 53b3ffee7885 ("ALSA: firewire-tascam: change device probing processing"), I addressed to the concern that version field in configuration differs depending on installed firmware. However, as long as I checked, the version number is fixed. It's safe to return version number back to modalias.

2020-09-09ALSA: firewire-digi00x: exclude Avid Adrenaline from detectionTakashi Sakamoto1-0/+5
commit acd46a6b6de88569654567810acad2b0a0a25cea upstream. Avid Adrenaline is reported that ALSA firewire-digi00x driver is bound to. However, as long as he investigated, the design of this model is hardly similar to the one of Digi 00x family. It's better to exclude the model from modalias of ALSA firewire-digi00x driver.

2019-10-05ALSA: firewire-tascam: check intermediate state of clock status and retryTakashi Sakamoto1-14/+28
commit e1a00b5b253a4f97216b9a33199a863987075162 upstream. 2 bytes in MSB of register for clock status is zero during intermediate state after changing status of sampling clock in models of TASCAM FireWire series. The duration of this state differs depending on cases. During the state, it's better to retry reading the register for current status of the clock. In current implementation, the intermediate state is checked only when getting current sampling transmission frequency, then retry reading. This care is required for the other operations to read the register. This commit moves the codes of check and retry into helper function commonly used for operations to read the register.

2019-10-05ALSA: firewire-motu: add support for MOTU 4preTakashi Sakamoto1-0/+12
[ Upstream commit 6af86bdb8ad41f4cf1292d3b10857dc322758328 ] 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> Signed-off-by: Sasha Levin <sashal@kernel.org>
2019-10-01ALSA: dice: fix wrong packet parameter for Alesis iO26Takashi Sakamoto1-1/+1
commit 3a9236e97207f2469254b4098995159b80174d95 upstream. At higher sampling rate (e.g. 192.0 kHz), Alesis iO26 transfers 4 data channels per data block in CIP. Both iO14 and iO26 have the same contents in their configuration ROM. For this reason, ALSA Dice driver attempts to distinguish them according to the value of TX0_AUDIO register at probe callback. Although the way is valid at lower and middle sampling rate, it's lastly invalid at higher sampling rate because because the two models returns the same value for read transaction to the register. In the most cases, users just plug-in the device and ALSA dice driver detects it. In the case, the device runs at lower sampling rate and the driver detects expectedly. For this reason, this commit leaves the way to detect as is.

2019-07-10ALSA: firewire-lib/fireworks: fix miss detection of received MIDI messagesTakashi Sakamoto1-1/+1
commit 7fbd1753b64eafe21cf842348a40a691d0dee440 upstream. In IEC 61883-6, 8 MIDI data streams are multiplexed into single MIDI conformant data channel. The index of stream is calculated by modulo 8 of the value of data block counter. In fireworks, the value of data block counter in CIP header has a quirk with firmware version v5.0.0, v5.7.3 and v5.8.0. This brings ALSA IEC 61883-1/6 packet streaming engine to miss detection of MIDI messages. This commit fixes the miss detection to modify the value of data block counter for the modulo calculation. For maintainers, this bug exists since a commit 18f5ed365d3f ("ALSA: fireworks/firewire-lib: add support for recent firmware quirk") in Linux kernel v4.2. There're many changes since the commit. This fix can be backported to Linux kernel v4.4 or later. I tagged a base commit to the backport for your convenience. Besides, my work for Linux kernel v5.3 brings heavy code refactoring and some structure members are renamed in 'sound/firewire/amdtp-stream.h'. The content of this patch brings conflict when merging -rc tree with this patch and the latest tree. I request maintainers to solve the conflict to replace 'tx_first_dbc' with 'ctx_data.tx.first_dbc'.

[ Upstream commit b2e9e1c8810ee05c95f4d55800b8afae70ab01b4 ] 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.

2019-03-27ALSA: firewire-motu: use 'version' field of unit directory to identify modelTakashi Sakamoto1-10/+10
commit 2d012c65a9ca26a0ef87ea0a42f1653dd37155f5 upstream. 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.

2019-03-19ALSA: firewire-motu: fix construction of PCM frame for capture directionTakashi Sakamoto1-1/+3
commit f97a0944a72b26a2bece72516294e112a890f98a upstream. 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.

2019-03-19ALSA: bebob: use more identical mod_alias for Saffire Pro 10 I/O against ↵Takashi Sakamoto1-1/+13
Liquid Saffire 56 commit 7dc661bd8d3261053b69e4e2d0050cd1ee540fc1 upstream. ALSA bebob driver has an entry for Focusrite Saffire Pro 10 I/O. The entry matches vendor_id in root directory and model_id in unit directory of configuration ROM for IEEE 1394 bus. On the other hand, configuration ROM of Focusrite Liquid Saffire 56 has the same vendor_id and model_id. This device is an application of TCAT Dice (TCD2220 a.k.a Dice Jr.) however ALSA bebob driver can be bound to it randomly instead of ALSA dice driver. At present, drivers in ALSA firewire stack can not handle this situation appropriately. This commit uses more identical mod_alias for Focusrite Saffire Pro 10 I/O in ALSA bebob driver. $ python2 crpp < /sys/bus/firewire/devices/fw1/config_rom ROM header and bus information block ----------------------------------------------------------------- 400 042a829d bus_info_length 4, crc_length 42, crc 33437 404 31333934 bus_name "1394" 408 f0649222 irmc 1, cmc 1, isc 1, bmc 1, pmc 0, cyc_clk_acc 100, max_rec 9 (1024), max_rom 2, gen 2, spd 2 (S400) 40c 00130e01 company_id 00130e | 410 000606e0 device_id 01000606e0 | EUI-64 00130e01000606e0 root directory ----------------------------------------------------------------- 414 0009d31c directory_length 9, crc 54044 418 04000014 hardware version 41c 0c0083c0 node capabilities per IEEE 1394 420 0300130e vendor 424 81000012 --> descriptor leaf at 46c 428 17000006 model 42c 81000016 --> descriptor leaf at 484 430 130120c2 version 434 d1000002 --> unit directory at 43c 438 d4000006 --> dependent info directory at 450 unit directory at 43c ----------------------------------------------------------------- 43c 0004707c directory_length 4, crc 28796 440 1200a02d specifier id: 1394 TA 444 13010001 version: AV/C 448 17000006 model 44c 81000013 --> descriptor leaf at 498 dependent info directory at 450 ----------------------------------------------------------------- 450 000637c7 directory_length 6, crc 14279 454 120007f5 specifier id 458 13000001 version 45c 3affffc7 (immediate value) 460 3b100000 (immediate value) 464 3cffffc7 (immediate value) 468 3d600000 (immediate value) descriptor leaf at 46c ----------------------------------------------------------------- 46c 00056f3b leaf_length 5, crc 28475 470 00000000 textual descriptor 474 00000000 minimal ASCII 478 466f6375 "Focu" 47c 73726974 "srit" 480 65000000 "e" descriptor leaf at 484 ----------------------------------------------------------------- 484 0004a165 leaf_length 4, crc 41317 488 00000000 textual descriptor 48c 00000000 minimal ASCII 490 50726f31 "Pro1" 494 30494f00 "0IO" descriptor leaf at 498 ----------------------------------------------------------------- 498 0004a165 leaf_length 4, crc 41317 49c 00000000 textual descriptor 4a0 00000000 minimal ASCII 4a4 50726f31 "Pro1" 4a8 30494f00 "0IO" $ python2 crpp < /sys/bus/firewire/devices/fw1/config_rom ROM header and bus information block ----------------------------------------------------------------- 400 040442e4 bus_info_length 4, crc_length 4, crc 17124 404 31333934 bus_name "1394" 408 e0ff8112 irmc 1, cmc 1, isc 1, bmc 0, pmc 0, cyc_clk_acc 255, max_rec 8 (512), max_rom 1, gen 1, spd 2 (S400) 40c 00130e04 company_id 00130e | 410 018001e9 device_id 04018001e9 | EUI-64 00130e04018001e9 root directory ----------------------------------------------------------------- 414 00065612 directory_length 6, crc 22034 418 0300130e vendor 41c 8100000a --> descriptor leaf at 444 420 17000006 model 424 8100000e --> descriptor leaf at 45c 428 0c0087c0 node capabilities per IEEE 1394 42c d1000001 --> unit directory at 430 unit directory at 430 ----------------------------------------------------------------- 430 000418a0 directory_length 4, crc 6304 434 1200130e specifier id 438 13000001 version 43c 17000006 model 440 8100000f --> descriptor leaf at 47c descriptor leaf at 444 ----------------------------------------------------------------- 444 00056f3b leaf_length 5, crc 28475 448 00000000 textual descriptor 44c 00000000 minimal ASCII 450 466f6375 "Focu" 454 73726974 "srit" 458 65000000 "e" descriptor leaf at 45c ----------------------------------------------------------------- 45c 000762c6 leaf_length 7, crc 25286 460 00000000 textual descriptor 464 00000000 minimal ASCII 468 4c495155 "LIQU" 46c 49445f53 "ID_S" 470 41464649 "AFFI" 474 52455f35 "RE_5" 478 36000000 "6" descriptor leaf at 47c ----------------------------------------------------------------- 47c 000762c6 leaf_length 7, crc 25286 480 00000000 textual descriptor 484 00000000 minimal ASCII 488 4c495155 "LIQU" 48c 49445f53 "ID_S" 490 41464649 "AFFI" 494 52455f35 "RE_5" 498 36000000 "6" Cc: <stable@vger.kernel.org> # v3.16+ Fixes: 25784ec2d034 ("ALSA: bebob: Add support for Focusrite Saffire/SaffirePro series") Signed-off-by: Takashi Sakamoto <o-takashi@sakamocchi.jp> Signed-off-by: Takashi Iwai <tiwai@suse.de> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
2019-01-26ALSA: bebob: fix model-id of unit for Apogee EnsembleTakashi Sakamoto1-1/+1
[ Upstream commit 644b2e97405b0b74845e1d3c2b4fe4c34858062b ] This commit fixes hard-coded model-id for an unit of Apogee Ensemble with a correct value. 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> Signed-off-by: Sasha Levin <sashal@kernel.org>

commit ada79fa5a0b374dd2c2262137c734da7524a8263 upstream. In IEC 61883-1/6 engine of ALSA firewire stack, a packet handler has a second argument for 'the number of bytes in payload of isochronous packet'. However, an incoming packet handler without CIP header uses the value as 'the number of quadlets in the payload'. This brings userspace applications to receive the number of PCM frames as four times against real time. This commit fixes the bug.

streaming DMA mapping When executing 'fw_run_transaction()' with 'TCODE_WRITE_BLOCK_REQUEST', an address of 'payload' argument is used for streaming DMA mapping by 'firewire_ohci' module if 'size' argument is larger than 8 byte. Although in this case the address should not be on kernel stack, current implementation of ALSA bebob driver uses data in kernel stack for a cue to boot M-Audio devices. This often brings unexpected result, especially for a case of CONFIG_VMAP_STACK=y. This commit fixes the bug.
