ALSA: mark all struct bus_type as const

2023-12-30T09:10:41+00:00

Now that the driver core can properly handle constant struct bus_type,
move all of the sound subsystem struct bus_type structures as const,
placing them into read-only memory which can not be modified at runtime.

Note, this fixes a duplicate definition of ac97_bus_type, which somehow
was declared extern in a .h file, and then static as a prototype in a .c
file, and then properly later on in the same .c file.  Amazing that no
compiler warning ever showed up for this.

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.

ALSA: hda: intel-nhlt: Ignore vbps when looking for DMIC 32 bps format

2023-11-27T16:20:58+00:00

When looking up DMIC blob from the NHLT table and the format is 32 bits,
ignore the vbps matching for 32 bps for DMIC since some NHLT table have
the vbps as 24, some have it as 32.
The DMIC hardware supports only one type of 32 bit sample size, which is
24 bit sampling on the MSB side and bits[1:0] is used for indicating the
channel number.

ALSA: hda: Refer to correct stream index at loops

2023-11-21T15:42:06+00:00

In a couple of loops over the all streams, we check the bitmap against
the loop counter.  A more correct reference would be, however, the
index of each stream, instead.

This patch corrects the check of bitmaps to the stream index.

Note that this change doesn't fix anything for now; all existing
drivers set up the stream indices properly, hence the loop count is
always equal with the stream index.  That said, this change is only
for consistency.

ALSA: hda: intel-dsp-config: Fix JSL Chromebook quirk detection

2023-10-20T15:39:44+00:00

Some Jasperlake Chromebooks overwrite the system vendor DMI value to the
name of the OEM that manufactured the device. This breaks Chromebook
quirk detection as it expects the system vendor to be "Google".

Add another quirk detection entry that looks for "Google" in the BIOS
version.
