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:

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.

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.

In the end we already enabled the sync-write mode for most of HD-audio controllers including Intel, and it's no big merit to keep the async write mode for the rest. Let's make it as default and drop the superfluous AZX_DCAPS_SYNC_WRITE bit flag. Also, avoid to set the allow_bus_reset flag, which is a quite unstable and hackish behavior that was needed only for some early platforms (decades ago). The straight fallback to the single cmd mode is more robust. Link: https://lore.kernel.org/r/20200618144051.7415-1-tiwai@suse.deSigned-off-by:

Set LED_CORE_SUSPENDRESUME to LED cdev flags, so that the LED core would store and restore the LED status at suspend/resume. In theory, the codec driver should be responsible for all LED bits, but this might be safer and cover the overlooked cases. Tested-by:

Both mute and mic-mute LED callbacks do almost similar tasks with just different bits. Factor out the common code and use them from the callbacks for simplification. This ended up with covering the forgotten stuff, too; e.g. VREF LED handling required the temporary power up/down that was missing for the mute LED, or some forgotten polarity checks are added.

Convert the mute LED handling in Sigmatel/IDT codec to the new vmaster mute helper. A point to be cautiously handled is that the value passed to the callback is inverted; the vmaster passes "enabled" (0 = mute), while LED classdev passes "brightness" (1 = mute). A positive side-effect by this change is that the driver gets also the enum controls for the mute behavior like other drivers already had. Tested-by:

A point to be cautiously handled is that the value passed to the callback is inverted; the vmaster passes "enabled" (0 = mute), while LED classdev passes "brightness" (1 = mute). Also the assignment of the default vmaster hook is moved at a later point after the mute hook is set up. This assures no nested hook. Finally, since we enable the mute-LED kcontrols always in the helper side, the extra vmaster_mute_enum flag set up is dropped. Tested-by:
