ALSA: hda: Move HD-audio core stuff into sound/hda/core

2025-07-11T07:55:36+00:00

This is a part of HD-audio code restructuring. Simply move the current code of sound/hda/* into the subdirectory sound/hda/core, so that more stuff can be moved into sound/hda cleanly later. Most of file names with hdac_ and hdac_ext_ prefix are renamed without the prefix, since they can be identified well in the directory name and superfluous.

ALSA: hda: Move widget capability macros into hdaudio.h

2025-07-11T07:55:36+00:00

The get_wcaps() and co are used not only by HD-audio core but also other driver code, hence it'd be better to put into the common header instead of local.h. OTOH, there are macros of the same name like get_wcaps() that are still used in sound/pci/hda/* locally, and those conflict with each other. So we need to rename get_wcaps() (to be moved from hda-core) with the proper snd_hdac prefix for avoiding name conflicts, and define in the common hdaudio.h.

ALSA: hda: Remove redundant pm_runtime_mark_last_busy() calls

2025-07-06T08:25:31+00:00

pm_runtime_put_autosuspend(), pm_runtime_put_sync_autosuspend(), pm_runtime_autosuspend() and pm_request_autosuspend() now include a call to pm_runtime_mark_last_busy(). Remove the now-reduntant explicit call to pm_runtime_mark_last_busy().

ALSA: hda: Allow for 16 channels configuration

As per HDAudio specification, up to 16 channels are supported. Reflect that in the code. Reviewed-by: Amadeusz Sławiński Signed-off-by: Cezary Rojewski Link: https://patch.msgid.link/20250404090337.3564117-3-cezary.rojewski@intel.com Signed-off-by: Mark Brown

ALSA: hda/senarytech: add senarytech codec support

2024-06-18T09:59:08+00:00

Add initial Senarytech codec support for SN6186. Note that this hda patch relies on the configuration default registers to be set correctly (normally by BIOS/firmware) in order for it to set up pin widgets properly.

PM: runtime: Simplify pm_runtime_get_if_active() usage

2024-02-12T15:57:47+00:00

There are two ways to opportunistically increment a device's runtime PM usage count, calling either pm_runtime_get_if_active() or pm_runtime_get_if_in_use(). The former has an argument to tell whether to ignore the usage count or not, and the latter simply calls the former with ign_usage_count set to false. The other users that want to ignore the usage_count will have to explicitly set that argument to true which is a bit cumbersome. To make this function more practical to use, remove the ign_usage_count argument from the function. The main implementation is in a static function called pm_runtime_get_conditional() and implementations of pm_runtime_get_if_active() and pm_runtime_get_if_in_use() are moved to runtime.c.

ALSA: hda: Upgrade stream-format infrastructure

2023-11-27T16:27:41+00:00

Introduce a set of functions that ultimately facilite SDxFMT-related calculations in atomic manner: First, introduce snd_pcm_subformat_width() and snd_pcm_hw_params_bits() helpers that separate the base functionality from the HDAudio-specific one. snd_hdac_format_normalize() - format converter. S20_LE, S24_LE and their unsigned and BE friends are invalid from HDAudio perspective but still can be specified as function argument due to compatibility reasons. snd_hdac_stream_format_bits() - obtain just the bits-per-sample value. Does not ignore subformat and msbits parameters. snd_hdac_stream_format() and snd_hdac_spdif_stream_format() - obtain the SDxFMT value given the audio format parameters. The former is stripped away of spdif-related information. Useful for users that do not care about them.

ALSA: hda: Honor subformat when querying PCMs

2023-11-27T16:24:27+00:00

Update mechanism for querying supported PCMs to allow for granular format selection when container size is 32 bits. Currently always the highest bit depth is selected, regardless of how many actual formats codec in question supports.
