[PATCH 00/17] ALSA/ASoC: hda: Address format selection limitations and ambiguity
Patchset aims to address format selection restrictions present currently in the HDAudio library. Formats which we are concerned about are 20 and 24 valid bits per sample within 32 bit depth container. One may identify them as S20_LE and S24_LE except that those, according to comments found in include/uapi/sound/asound.h, are for LSB-aligned scenarios. HDAudio streams expect MSB-aligned data, no matter if we are speaking of HOST (SDxFMT) or LINK (PPLCxFMT) side - chapter 4.5.1 of the public HDAudio specification. In short, S20_LE and S24_LE are invalid options.
Right now, given the implementation of snd_hdac_query_supported_pcm() within sound/hda/hdac_device.c, even if a codec responds with: "I support all possible formats specified within HDAudio specification", there will be no option to open a 20/32 or 24/32 stream. The kernel will force the stream to be opened using the highest available bit depth.
After discussing subject initially with Jaroslav and Takashi, suggestion was made to utilize 'subformat' option to address the problem. The eye-opening discussion begun much earlier though, in 2019 [1].
Paired with PRs for alsa-utils [2] and alsa-lib [3].
Flow of changes:
The very first patch adds MSBITS subformat options to allow for granular 20/32, 24/32 and 32/32 format selection. The next three make sure subformat is actually honored during runtime. Most of that code is based on format-related API.
Follow up is upgrade to the hda stream-format interface - several functions are added to make the granular format selection simple in the HDAudio world. Core of the implementation is based on the existing snd_hdac_calc_stream_format(). The next ten patches are straightforward switch from one interface to another with cleanup of now-unsed function as a finishing touch.
Last but not least - the avs-driver, on which the problem analyzed and debugged, is updated to no longer acknowledge S24_LE as a valid format option.
Results with skylake-driver and snd_hda_intel show status quo on our RVPs. PR filed on SOF github shows promissing results too [4].
Changes in v1: - fixed UBSAN due to missing snd_pcm_subformat_names[] entries for new subformats - as HDMI stream capabilities are assigned on PCM open, patch 16/17 has been updated to ignore such codecs for now. A separate patchset will take care of this case - params_bps() reworded to snd_pcm_hw_params_bps() - fixed compilation issues in sof-driver, patch 13/17

base-commit: e69dadf638e625a950b2b91591a47c9ae32a9d5e
Improve granularity of format selection for S32/U32 formats by adding constants representing 20, 24 and 32 most significant bits.
To make it easy for drivers to utilize those constants, introduce snd_pcm_subformat_width() and snd_pcm_hw_params_bps(). While the former is self-explanatory, the latter returns the bit-per-sample value based on format, subformat and msbits characteristics of the provided hw_params.

Substream value is currently hardcoded to SNDRV_PCM_SUBFORMAT_STD. Update the constraint procedure so that subformat selection is not ignored.

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.

Subformat options are ignored when setting up hardware parameters and assigning PCM stream capabilities. Account for them to allow for granular format selection.

Subformat options are ignored when setting up hardware parameters and assigning PCM stream capabilities. Account for them to allow for granular format selection.

Introduce a set of functions that facilite SDxFMT-related calculations in atomic manner:
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_bps() - 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.

To not expose more than in fact is supported by the codec, update CPU DAI initialization procedure to rely on codec capabilities instead of hardcoding them. This includes subformat which is currently ignored.
As capabilities for HDMI streams are initialized on PCM open, leave it as is for now.
