2020-01-16ALSA: pcm: Make snd_pcm_hw_constraints_init() and _complete() staticTakashi Iwai2-5/+2
Both snd_pcm_hw_constraints_init() and _complete() functions are called only from pcm_native.c, hence they can be static for further optimization. Link: https://lore.kernel.org/r/20200116162825.24792-1-tiwai@suse.de Signed-off-by: Takashi Iwai <tiwai@suse.de>
2020-01-16ALSA: hda/analog - Minor optimization for SPDIF mux connectionsTakashi Iwai1-5/+9
AD HD-audio codec driver has a few code lines invoking snd_get_num_conns() and using its return value as the array index without checking. This is basically safe in all those places; at the second and later calls snd_get_num_conns() returns the value cached from the first invocation, hence the value is always consistent. However, it looks a bit confusing as if a lack of the proper check. This patch introduces a new field num_smux_conns in ad198x_spec for simplifying the code. Now we store and refer to the value more locally without invoking the extra function at each time.

2020-01-16ALSA: usb-audio: add implicit fb quirk for MOTU M SeriesAlexander Tsoy1-0/+4
This fixes crackling sound during playback. Further note: MOTU is known for reusing Product IDs for different devices or different generations of the device (e.g. MicroBook I/II/IIc shares a single Product ID). This patch was only tested with M4 audio interface, but the same Product ID is also used by M2. Hope it will work for M2 as well.

2020-01-13ALSA: hda: Manage concurrent reg access more properlyTakashi Iwai10-54/+135
In the commit 8e85def5723e ("ALSA: hda: enable regmap internal locking"), we re-enabled the regmap lock due to the reported regression that showed the possible concurrent accesses. It was a temporary workaround, and there are still a few opened races even after the revert. In this patch, we cover those still opened windows with a proper mutex lock and disable the regmap internal lock again. First off, the patch introduces a new snd_hdac_device.regmap_lock mutex that is applied for each snd_hdac_regmap_*() call, including read, write and update helpers. The mutex is applied carefully so that it won't block the self-power-up procedure in the helper function. Also, this assures the protection for the accesses without regmap, too. The snd_hdac_regmap_update_raw() is refactored to use the standard regmap_update_bits_check() function instead of the open-code. The non-regmap case is still open-coded but it's an easy part. The all read and write operations are in the single mutex protection, so it's now race-free. In addition, a couple of new helper functions are added: snd_hdac_regmap_update_raw_once() and snd_hdac_regmap_sync(). Both are called from HD-audio legacy driver. The former is to initialize the given verb bits but only once when it's not initialized yet. Due to this condition, the function invokes regcache_cache_only(), and it's now performed inside the regmap_lock (formerly it was racy) too. The latter function is for simply invoking regcache_sync() inside the regmap_lock, which is called from the codec resume call path. Along with that, the HD-audio codec driver code is slightly modified / simplified to adapt those new functions. And finally, snd_hdac_regmap_read_raw(), *_write_raw(), etc are rewritten with the helper macro. It's just for simplification because the code logic is identical among all those functions.

2020-01-13ALSA: usb-audio: Add boot quirk for MOTU M SeriesAlexander Tsoy3-0/+47
Add delay to make sure that audio urbs are not sent too early. Otherwise the device hangs. Windows driver makes ~2s delay, so use about the same time delay value. snd_usb_apply_boot_quirk() is called 3 times for my MOTU M4, which is an overkill. Thus a quirk that is called only once is implemented. Also send two vendor-specific control messages before and after the delay. This behaviour is blindly copied from the Windows driver.

Alesis MasterControl was shipped 2009 and already discontinued. This model consists of: * TSB41AB2 for physical layer of IEEE 1394 * WaveFront Dice II STD for link layer and protocol implementation * FreeScale DSPB56374AE Although the firmware of this model can respond against read transaction to address space for TCAT extension protocol, the content is not valid for protocol extension.

2020-01-13ALSA: dice: loosen stream format check for MIDI conformant data channelTakashi Sakamoto1-6/+3
ALSA dice driver expects devices to multiplex MIDI messages into first port of isochronous communication. Actually devices perform for it. However, check of stream format is invalid for second port of isochronous communication. As a result, when the device supports two ports for isochronous communication and the stream format is hard-coded, ALSA dice driver fails to start packet streaming. This commit loosens stream format check for MIDI conformant data channel.

2020-01-13ALSA: oxfw: fix for Stanton SCS.1dTakashi Sakamoto1-30/+42
Stanton SCS.1d uses Oxford Semiconductor FW 971 ASIC (FW971) for communication. Although the unit is bound to ALSA oxfw driver, the instance of sound card can not be added due to its quirk of plug information. This bug was added when snd-scs1x is merged into snd-oxfw at commit 9e2004f9cedf ("ALSA: oxfw: obsolete scs1x module"). This commit fixes the driver for the quirk. In cases that the unit returns NOT IMPLEMENTED for some AV/C commands, the sound card is added without any PCM/MIDI interfaces for packet streaming. For SCS.1d, model dependent operation adds MIDI interface and applications can use it to operate according to HSS1394 protocol from reverse-engineering work by Sean M. Pappalardo. Plug Control Register (PCR) has information that the unit has a pair of plugs for isochronous communication: (oMPR) $ ./firewire-request /dev/fw1 read 0xfffff0000900 result: 80ff0001 (iMPR) $ ./firewire-request /dev/fw1 read 0xfffff0000980 result: 80ff0001 AV/C PLUG INFO also returns information that the unit has a pair of plugs for isochronous communication.

2020-01-11ALSA: hda: Rename back to dmic_detect optionTakashi Iwai1-5/+8
We've got quite a few bug reports showing the SOF driver being loaded unintentionally recently, and the reason seems to be that users didn't know the module option change: with the recent kernel, a new option dsp_driver=1 has to be passed to a new module snd-intel-dspcfg instead of snd_hda_intel.dmic_detect=0 option. That is, actually there are two tricky things here: - We changed the whole detection in another module and another option semantics. - The existing option for skipping the DSP probe was also renamed. For avoiding the confusion and giving user more hint, this patch reverts the renamed option dsp_driver back to dmic_detect for snd-hda-intel module, and show the warning about the module option change when the non-default value is passed.
