Commit f34a4c9dd4ca ("ALSA: hda: Enable sync-write operation as default for all controllers") enabled sync-write for all controllers and this is causing audio playback on the Tegra186 HDA device to fail.

2020-07-09ALSA: echoaudio: Address bugs in the interrupt handlingMark Hills
Distorted audio appears occasionally, affecting either playback or capture and requiring the affected substream to be closed by all applications and re-opened. The best way I have found to reproduce the bug is to use dmix in combination with Chromium, which opens the audio device multiple times in threads. Anecdotally, the problems appear to have increased with faster CPUs. I ruled out 32-bit counter wrapping; it often happens much earlier. Since applying this patch I have not had problems, where previously they would occur several times a day. The patch targets the following issues: * Check for progress using the counter from the hardware, not after it has been truncated to the buffer. This is a clean way to address a possible bug where if a whole ringbuffer advances between interrupts, it goes unnoticed. * Move last_period state from chip to pipe This more logically belongs as part of pipe, and code is reasier to read if it is "counter position last time a period elapsed". Now the code has no references to period count. A period is just when the regular counter crosses a threshold. This increases readability and reduces scope for bugs. * Treat period notification and buffer advance independently: This helps to clarify what is the responsibility of the interrupt handler, and what is pcm_pointer(). Removing shared state between these operations means race conditions are fixed without introducing locks. Synchronisation is only around the read of pipe->dma_counter. There may be cache line contention around "struct audiopipe" but I did not have cause to profile this. Pay attention to be robust where dma_counter wrapping is not a multiple of period_size or buffer_size. This is a revised patch based on feedback from Takashi and Giuliano.

2020-07-09ALSA: echoaudio: Race conditions around "opencount"Mark Hills
Use of atomics does not make these statements robust: atomic_inc(&chip->opencount); if (atomic_read(&chip->opencount) > 1 && chip->rate_set) chip->can_set_rate=0; and if (atomic_read(&chip->opencount)) { if (chip->opencount) { changed = -EAGAIN; } else { changed = set_digital_mode(chip, dmode); It would be necessary to atomically increment or decrement the value and use the returned result. And yet we still need to prevent other threads making use of "can_set_rate" while we set it. However in all but one case the atomic is misleading as they are already running with "mode_mutex" held. Decisions are made on mode setting are often intrinsically connected to "opencount" because some operations are not permitted unless there is sole ownership. So instead simplify this, and use "mode_mutex" as a lock for all reference counting and mode setting.

2020-07-07ALSA: pcm: Fix build error on m68k and othersTakashi Iwai
The commit 3ad796cbc36a ("ALSA: pcm: Use SG-buffer only when direct DMA is available") introduced a check of the DMA type and this caused a build error on m68k (and possibly some others) due to the lack of dma_is_direct() definition. Since the check is needed only for CONFIG_SND_DMA_SGBUF enablement (i.e. solely x86), use #ifdef instead of IS_ENABLED() for avoiding such a build error.

2020-07-07ALSA: hda/hdmi: Add Intel silent stream supportHarsha Priya
External HDMI receivers have analog circuitry that needs to be powered-on when exiting standby, and a mechanism to detect PCM v. IEC61937 data. These two steps take time and up to 2-3 seconds of audio may be muted when starting playback. Intel hardware (Haswell and beyond) can keep the link active with a 'silent stream', so that the receiver does not go through those two steps when valid audio is transmitted. This mechanism relies on an setting the channel_id as 0xf, sending info packet and preventing the codec from going to D3, which will increase the platform static power consumption. The info packet assumes a basic 2ch stereo, and the silent stream is enabled when connecting a monitor. In case of format changes the detection of PCM v. IEC61937 needs to be re-run. In this case there is no way to avoid the 2-3s mute. The silent stream is enabled with a Kconfig option, as well as a kernel parameter should there be a need to override the build time default. This approach is used based on the power_save capability as an example, but in the future, it may be used with a kcontrol, depending on UCM support for HDaudio legacy.

2020-06-25ALSA: core: Warn on empty moduleTakashi Iwai
The module argument passed to snd_card_new() must be a valid non-NULL pointer when the module support is enabled. Since ASoC driver passes the argument from each snd_soc_card definition, one may forget to set the owner field and lead to a NULL module easily. For catching such an overlook, add a WARN_ON() in snd_card_new(). Also, put the card->module assignment in the ifdef block for a very minor optimization.

2020-06-19Merge branch 'topic/hda-micmute-led' into for-nextTakashi Iwai
This is a patch set inspired by the recent patch Kai-Heng posted about the HD-audio mic-mute LED control. Currently HD-audio driver deals with the mute and mic-mute LED in several different ways: primarily with the direct callback of vmaster hook and capture sync hook, while another with the LED class device binding. The latter has been used for binding with the platform device LEDs like Thinkpad, Dell, Huawei. And, yet, recently we added our own LED classdev for the mic-mute LED on some HP systems although they are controlled directly with the callback; it's exposed, however, for the DMIC that is governed by a different ASoC driver. This patch set is an attempt to sort out and make them consistent: namely, * All LEDs are now controlled via LED class device * The generic driver provides helper functions to easily build up the LED class dev and the relevant mixer controls * Conversion of the existing framework and clean ups The patches are lightly tested in my side with a couple of machines and also through hda-emu tests. Some devices receive new kcontrols for the mute LED behavior (that have been missing so far), but anything else look good though my tests.
