[PATCH 00/13] ALSA: update sample rate definitions

[PATCH 00/13] ALSA: update sample rate definitions

[Jerome Brunet]

This patchset adds rate definitions for 12kHz, 24kHz and 128kHz.

It is follow-up on the series/discussion [0] about adding 128kHz for
spdif/eARC support. The outcome was to add 12kHz and 24kHz as well and
clean up the drivers that no longer require custom rules to allow these
rates.

Identifying these drivers is not straight forward, I tried my best but I
may have missed some. Those will continue to work anyway so it is not
critical. Some drivers using these rates have not been changed on
purpose. The reason for this may be:
* The driver used other uncommon rates that still don't have a definition
  so a custom rule is still required.
* The constraint structure is used in some other way by the driver and
  removing it would not help the readability or maintainability. This is
  the case the freescale asrc drivers for example.

There is one change per driver so, if there is a problem later on, it will
easier to properly add Fixes tag.

The series has been tested with
* ARM64 defconfig - spdif 128kHz at runtime.
* x86_64 allmodconfig - compile test only

Last, the change adding IEC958 definitions has been dropped for this
patchset and will be resent separately

[PATCH 01/13] ALSA: pcm: add more sample rate definitions

[Jerome Brunet]

This adds a sample rate definition for 12kHz, 24kHz and 128kHz.

Admittedly, just a few drivers are currently using these sample
rates but there is enough of a recurrence to justify adding a definition
for them and remove some custom rate constraint code while at it.

The new definitions are not added to the interval definitions, such as
SNDRV_PCM_RATE_8000_44100, because it would silently add new supported
rates to drivers that may or may not support them. For sure the drivers
have not been tested for these new rates so it is better to leave them out
of interval definitions.

That being said, the added rates are multiples of well know rates families,
it is very likely that a lot of devices out there actually supports them.

Almost wonder if a comment with the SNDRV_PCM_RATE_8000_xxx
defines might also be an idea to warn they don't include all the
rates, although it is I guess easily seen from the define itself
so not sure if it might be over kill. But I am happy either way.

Wondering if this is backwards compatible with the alsa-lib definitions,
specifically the topology parts which did unfortunately have a list of
rates that will map to a different index now:


typedef enum _snd_pcm_rates {
	SND_PCM_RATE_UNKNOWN = -1,
	SND_PCM_RATE_5512 = 0,
	SND_PCM_RATE_8000,
	SND_PCM_RATE_11025,
	SND_PCM_RATE_16000,
	SND_PCM_RATE_22050,
	SND_PCM_RATE_32000,
	SND_PCM_RATE_44100,
	SND_PCM_RATE_48000,
	SND_PCM_RATE_64000,
	SND_PCM_RATE_88200,
	SND_PCM_RATE_96000,
	SND_PCM_RATE_176400,
	SND_PCM_RATE_192000,
	SND_PCM_RATE_CONTINUOUS = 30,
	SND_PCM_RATE_KNOT = 31,
	SND_PCM_RATE_LAST = SND_PCM_RATE_KNOT,
} snd_pcm_rates_t;

As far as I understand correctly, those rate bits used for topology
are independent from the bits used for PCM core, although it used to
be the same.  Maybe better to rename (such as SND_TPLG_RATE_*) so that
it's clearer only for topology stuff.

But it'd be better if anyone can double-check.

Even if we rename these in alsa-lib we will need translation from
SND_TPLG_RATE_ to SND_PCM_RATE_ in kernel likely?

The topology files are out there and this is an ABI...

Since the kernel just copies the rates bitfield, any rate above 11025
will be misaligned and result broken setup.

Yep, I noticed it now, too.

Below is the fix patch, totally untested.
It'd be appreciated if anyone can test it quickly.

Subject: [PATCH] ALSA: pcm: Fix breakage of PCM rates used for topology

It turned out that the topology ABI takes the standard PCM rate bits
as is, and it means that the recent change of the PCM rate bits would
lead to the inconsistent rate values used for topology.

This patch reverts the original PCM rate bit definitions while adding
the new rates to the extended bits instead.  This needed the change of
snd_pcm_known_rates, too.  And this also required to fix the handling
in snd_pcm_hw_limit_rates() that blindly assumed that the list is
sorted while it became unsorted now.

This looks fine. But the topology rate bits should not depend on those bits. 
It's a bit pitty that the standard PCM ABI does not use those bits for user 
space and we are doing this change just for topology ABI.

Yeah, and theoretically it's possible to fix in topology side, but
it'll be more cumbersome.

Although it's not really a part of PCM ABI, I believe we should move
the PCM rate bit definitions to uapi, for showing that it's set in
stone.  Something like below.

Subject: [PATCH] ALSA: pcm: Move standard rate bit definitions into uapi

Since the standard PCM rate bits are used for the topology ABI, it's a
part of public ABI that must not be changed.  Move the definitions
into uapi to indicate it more clearly.

It is cosmetic but I wonder, does the extended really start here ?

From the table Pierre-Louis sent, I suppose that all the recently added rates could
been seen as extended too (352.8 to 768). Those did not mess with the
order though

Maybe a bad choice of the words.  This was rather meant as the
extension since 6.12.  So I'll replace it with "extended rates since
6.12", to be clearer.

AFAIU, the topology stuff seems supporting only up to 192kHz for now,
but it's a matter of topology-only; the limitation could be commented
in somewhere in topology's headers, but it's basically independent
from the definitions in pcm.h.

I will just note that alternatively we could bump topology ABI (wouldn't 
be first time) and provide mapping in soc-topology.c for current one.

For ABI+1 we could remove the field from problematic topology struct to 
not make SNDRV_PCM_RATE_* part of UAPI and provide some other way to 
pass expected rates.

I've quickly tested this version with a few rates (48, 128, 768k),
amlogic device.

Looks Ok.

... and I double-check by myself and proved I was wrong :-<

In soc-topology.c, set_stream_info() takes the
snd_soc_pcm_stream.rates bits as is from the given topology data,
so the changes of the bits can break this.

The topology takes both rates and formats bits.  The formats are a
part of uapi, but the rates aren't.  We should move those into uapi,
if any...

[PATCH 02/13] ALSA: cmipci: drop SNDRV_PCM_RATE_KNOT

[Jerome Brunet]

The custom rate constraint list was necessary to support 128kHz.
This rate is now available through SNDRV_PCM_RATE_128000.

Use it and drop the custom rate constraint rule.

[PATCH 03/13] ALSA: emu10k1: drop SNDRV_PCM_RATE_KNOT

[Jerome Brunet]

The custom rate constraint lists were necessary to support 12kHz and 24kHz.
These rates are now available through SNDRV_PCM_RATE_12000 and
SNDRV_PCM_RATE_24000.

Use them and drop the custom rate constraint rules.

[PATCH 09/13] ASoC: Intel: avs: drop SNDRV_PCM_RATE_KNOT

[Jerome Brunet]

The custom rate constraint list was necessary to support 12kHz, 24kHz and
128kHz. These rates are now available through SNDRV_PCM_RATE_12000,
SNDRV_PCM_RATE_24000 and SNDRV_PCM_RATE_128000.

Use them and drop the custom rate constraint rule.

[PATCH 12/13] ASoC: cs35l34: drop useless rate contraint

[Jerome Brunet]

The cs35l34 adds a useless rate constraint on startup.
It does not set SNDRV_PCM_RATE_KNOT and the rates set are already a subset
of the ones provided in the constraint list, so it is a no-op.

From the rest of the code, it is likely HW supports more than the 32, 44.1
and 48kHz listed in CS35L34_RATES but there is no way to know for sure
without proper documentation.

Keep the driver as it is for now and just drop the useless constraint.

Yeah according to the datasheet it should support all the rates
listed in the cs35l34_src_rates list. But given the weird way
that CS35L34_RATES is implemented I think you are right best to
leave it as it is for now, incase there was a reason. Perhaps if
I find some time I might see if I have one in a draw somewhere in
the future.
