Follow the recent inclusive terminology guidelines and replace the word "slave" in vmaster API. I chose the word "follower" at this time since it seems fitting for the purpose. Note that the word "master" is kept in API, since it refers rather to audio master volume control. Also, while we're at it, a typo in comments is corrected, too.

Rationale: Reduces attack surface on kernel devs opening the links for MITM as HTTPS traffic is much harder to manipulate. Deterministic algorithm: For each file: If not .svg: For each line: If doesn't contain `\bxmlns\b`: For each link, `\bhttp://[^# \t\r\n]*(?:\w|/)`: If neither `\bgnu\.org/license`, nor `\bmozilla\.org/MPL\b`: If both the HTTP and HTTPS versions return 200 OK and serve the same content: Replace HTTP with HTTPS.

This reverts commit 3ad796cb ("ALSA: pcm: Use SG-buffer only when direct DMA is available") also the modification commit 467fd0e8 ("ALSA: pcm: Fix build error on m68k and others"). Poking the DMA internal helper is a layer violation, so we should avoid that. Meanwhile the actual bug has been addressed by the Kconfig fix in commit dbed452a ("dma-pool: decouple DMA_REMAP from DMA_COHERENT_POOL"), so we can live without this hack.

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. Signed-off-by:

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. Signed-off-by: -

This check is always false, as it's not the responsibilty of the device-specific code to make this check. It is already checked in snd_echo_digital_mode_put. I do not have a Mona interface to test this change. This patch is in preparation for follow-up patch to modify the behavior of "opencount". Signed-off-by:

The commit 3ad796cb ("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.

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. Signed-off-by:
