Add generic ASoC equivalent of ALSA HD-Audio codec. This codec is
designed to follow HDA_DEV_LEGACY convention. Driver wrapps existing
hda_codec.c handlers to prevent code duplication within the newly added
code. Number of DAIs created is dependent on capabilities exposed by the
codec itself. Because of this, single solution can be applied to support
every single HD-Audio codec type.
At the same, through the ASoC topology, platform drivers may limit the
number of endpoints available to the userspace as codec driver exposes
BE DAIs only.
Both hda_codec_probe() and hda_codec_remove() declare their expectations
on device's usage_count and suspended-status. This is to catch any
unexpected behavior as PM-related code for HD-Audio has been changing
quite a bit throughout the years.
In order for codec DAI list to reflect its actual PCM capabilities, PCMs
need to be built and that can only happen once codec device is
constructed. To do that, a valid component->card->snd_card pointer is
needed. Said pointer will be provided by the framework once all card
components are accounted for and their probing can begin. Usage of
"binder" BE DAI solves the problem - codec can be listed as one of
HD-Audio card components without declaring any actual BE DAIs
statically.

I am surprised the explanations don't even mention the existence of hdac_hda.c
/*
* hdac_hda.c - ASoC extensions to reuse the legacy HDA codec drivers
* with ASoC platform drivers. These APIs are called by the legacy HDA
* codec drivers using hdac_ext_bus_ops ops.
*/
I thought the series was about adding machine drivers, but this also adds code on the sound/soc/codecs/ side which I didn't see coming.
I am not qualified to review this part of the code, I just wonder about duplication of functionality.
At the very least an explanation on why you decided to NOT use hdac_hda.c would be useful to reviewers and maintainers.
Thanks.

Right, why the duplication here? Can't we fix or extend the
existing code to do whatever it's not currently doing which
compels reimplementation?

Sorry for the late response, did not realize there is an unanswered
comment here.
So, the rough list goes as:
- hdac_hda.c hardcodes codec capabilities rather than aligning with what
sound/pci/hda/ code does
- merges HDMI (i.e. Intel i915 audio component) and HDA DAIs together
whereas these are two separate devices
- because of above, implements custom search/matching mechanism for PCM/DAI
- cont. because of above, its header hosts private data struct,
unnecessary complication
- follows HDA_DEV_ASOC convention rather than HDA_DEV_LEGACY causing
misalignments between sound/pci/hda and sound/soc/ behaviour
- has basic PM runtime support and does not survive scenarios where
resume/suspend + denylist + rmmod/modprobe are mixed together or invoked
in unordered fashion between this module and several others in the audio
stack
My suggestion is different: have all HD-Audio ASoC users switch to this
implementation when possible and remove the existing code along with
skylake-driver.

Czarek

I am not against change and will agree that HDaudio support is far from
perfect, but it's been released for multiple generations from dozens of
OEMs and mostly works. All the issues reported to us are related to
codec configurations that also don't work with the legacy HDaudio
driver, DMIC configurations, CSME authentication or system hangs that
have not been root-caused [1]. HDaudio/ASoC interfaces are not on our
radar as problematic.
Disrupting basic HDaudio support to do things better has to be handled
with extreme caution and a ton of testing involving distro maintainers
and community members, so we are talking about an opt-in transition, not
an immediate switch. We've done a similar transition in the past to stop
using a dedicated hdac_hdmi.c codec, see all references to the
'use_common_hdmi' parameter in the SOF code. That transition seems to go
exactly against your second point above on HDMI and HDA being different
devices, so this could be an interesting debate.
Changes to the HDAudio/ASoC support would need to be handled with a
separate patchset anyways, and the SOF side changes done after we are
finished with the IPC4 and MeteorLake upstreaming. No one in our team
has any bandwidth to help with reviews or tests on this topic at the moment.
I will also re-state that the removal of the skylake driver can only
happen after a long period of deprecation, when firmware and topologies
have been picked by distributions and all users are known to have
switched, so it's very likely that any alignment between "all HD-Audio
ASoC users" mentioned above does include the Skylake driver, doesn't it?
So to circle back: is there anything preventing the use of the existing
hdac_hda.c codec in this "ASoC: Intel: avs: Machine boards and HDA codec
support" series and can the HDaudio codec change be done "later" in a
more organized way?
Thanks!

That's why aligning with sound/pci/hda behavior is better for both, ALSA
and ASoC users -> one place to fix the problems, both clients happy.

Agree. This won't be forced on anyone and that's why separate
implementation needed to be provided. There is too much to cover if we
were to refactor hdac_hda.c

Nah, I don't believe we need to be saving skylake-driver here. By "all
HD-Audio ASoC users" I meant sof-driver as it isn't going anywhere -
what cannot be said about the skylake-driver :)

Yeah, all the pm scenarios will fail when paired with the avs-driver.
The expectations are different. We'd have to fix probe() and remove()
(and related) sequences for the hdac_hda.c, and given that its users did
not notice prompts further problems with the refactor. This is very
similar to the skylake-driver vs avs-driver case. We could have applied
~300 patches we had internally that prepare skylake-driver to be
re-modeled and then apply patchsets which look more or less like the
avs-driver series instead of providing a parallel driver.
But the reality shows that such approach applies too much pressure on
the reviewers and leaves no fallback option for the end users if
anything fails along the way.

I will stop commenting here to let others chime in, I don't have the
background to provide useful technical feedback on this complicated
HDaudio/ASoC interface.
I am however concerned about the lack of long-term plans and confusion
coming having 3 different ways of dealing with HDaudio codecs on the
same hardware platform (legacy, ASoC/SOF-Skylake, ASoC-AVS). 2 was
already bad, I don't see how 3 is better?

fortunately most of the actual logic is in the codec drivers (in
sound/pci/hda/), so redundancy in the asoc-to-hda wrappers is not that
bad.
As a slight correction to the thread, hdac_hda.c does support HDMI and all
SOF machine drivers transitioned to this a few years back (and dropped
use of hdac_hdmi.c which is mostly duplicating code in patch_hdmi.c).
In last few years, most of the changes have been to the actual codec
drivers and we've not really had many fixes to hdac_hda.c anymore (there
has been a few, and indeed PM related). So in this sense this has worked
well enough. Patches to fix bugs and add support for new hardware, have
benefitted all users (DSP and no-DSP) and changes have been only needed at
a single location. So this is all good.
The fixed DAI capabilities of hdac_hda.c are indeed not ideal (although in
practise hasn't really been an issue so far) and the approach in the new
hda.c seems indeed more robust. We do have a lot of existing machine
drivers (and shipping DSP topologies that we need to keep working), so
transitioning e.g. SOF machine drivers is not going to be straightforward.
For new mach drivers, this could be considered.
So while not ideal, maybe it makes sense to have two wrappers, hdac_hda.c
for mach drivers with fixed DAI configuration, and the new hda.c that
supports dynamic configuration (but requires mach drivers that match
this). If the old SST driver is deprecated, we can then proceed to remove
hdac_hdmi.c from the tree, so there's some savings.
Please do add some description to the commit+code+kconfig on how this new
codec driver relates to hdac_hda. Otherwise it's very confusing to have
two asoc codec drivers for the same thing.
Br, Kai

We've just simplified the HDAudio topologies to support the Analog
playback and capture only, for both IPC3 and IPC4 cases, so there's
really no plan to support such dynamic capabilities. I am not even aware
of a single device available in our team where the digital inputs and
outputs are exposed on a connector, so even if we wanted we couldn't
test this dynamic part.

Such removal isn't going to happen for at least 3+ years, the time it
takes for the slowest distros and users to switch kernels.
that means we're going to have to maintain for the foreseeable future:
hdac_hdmi.c: used only by SST
hdac_hda.c: used by both SST and SOF
hda.c: used only by AVS.

As I've explained in one of the previous posts, you can always use
topology to limit the number of FE(s) available while still adhering to
behavior found in sound/pci/hda. hda.c is a prime example of how ASoC
HD-Audio can align with ALSA HD-Audio in 1:1 fashion. hdac_hda.c does
not do that a) because of hardcodes b) following HDA_DEV_ASOC.
Having no behavioral differences is a major gain here, fix one place,
enjoy both solutions. By 'one place' I mean sound/pci/hda of course as
there should be no logic outside of that directory.

I and the team maintained almost all the solutions found in
sound/soc/intel for couple of years already, doing couple more with the
old stuff is not a problem. Don't believe 'sit and do nothing' is the
answer here, not sure if this is even an option - but I'm sure that the
final effect is going to be worth the initial cost.

Connect AVS driver with ASoC HDAudio codec with help of this machine
board. Similarly to its platform and codec components, DAI links and
routes are being created dynamically so single board can be used across
all HDAudio codec types.
Card makes use of "binder" BE DAI Link so HDAudio codec driver can be
listed as one of its components. This allows for BE DAIs to be created
dynamically, based on HDAudio codec capabilities.

Allow for testing audio streaming over I2S interface through SSP-test
board. No actual codec is needed here as board is intended for SSP
loopback scenarios only. One playback and one capture endpoint is
exposed per SSP port.
