ASoC: SOF: Intel: don't ignore IOC interrupts for non-audio transfers
The HDaudio stream interrupts are ignored unless the stream is PCM or
compressed audio. For alternate non-audio usages, such as code loader
or SoundWire BPT case, the IOC interrupt on the last buffer
transferred is silently ignored.
This patch adds a 'struct completion' for each HDaudio stream. This
capability helps detect if the non-audio data transfers
completed. There is no performance impact for audio streams.
In the code loader case, the code currently starts the DMA and
directly checks if the firmware status changes, without checking if
the DMA succeeded. With a first pass waiting for the DMA to complete,
system validation engineers can gather more precise timing information
on firmware boot time or root-cause boot failures more accurately.
A timeout of 500ms was selected for the code loader DMA. This is an
experimental value which should be more than enough - higher values
would certainly be problematic from a usage/latency perspective.
ASoC: SOF: Intel: hda-loader: change signature of code loader helpers
We need to reuse cl_prepare, cl_trigger and cl_cleanup helpers from a
SoundWire context where only the device information is
available. Rather than pass the 'sdev' argument, use get_drvdata() to
retrieve the required structure.
For consistency, rename hda_cl_stream_prepare() as hda_cl_prepare().
These three helpers are also exported so that they can be referenced
from another module.
ASoC: SOF: Intel: hda-loader: add flag to tag ICCMAX stream
The existing code conflates capture stream and ICCMAX stream. This

No functionality change, only future-proofing change.

This patchset contains important updates for SoundWire support.
We initially implemented support for multiple amplifiers on different
links using a single HDaudio DMA transfer. To align with the other OS,
the 'aggregation' is now supported by the firmware. This change in
directions has kernel impacts, since we now have multiple HDaudio DMAs
to program and start, but since there are no platforms released so far
there's no end-user impact.
In addition, the behavior in case of xruns is improved by clearing the
PCM states and better handling of the hw_free case.
Note that the hw_free support will compile but will only be functional
with the companion patch "soundwire: intel: add intel_free_stream() back"
already applied in the SoundWire tree.
The first two patches change snd_soc_card_get_kcontrol() to use the
core snd_ctl_find_id_mixer() functionality instead of open-coding its
own list walk.
The last patch adds a KUnit test for this, which was tested on the
original and modified code.
Also correct the 'dai-format' to 'format' in document.
For 'audio-routing', the items are not listed. Because
this fsl-asoc-card is generic driver, which supports several
codecs, if list all the items, there will be a long list.
ASoC: SOF: ipc4-topology: Save the ALH DAI index during hw_params
The node_id for multi-gateway ALH DAI's get overwritten with the
group_id during the DAI copier's ipc_prepare op. So, save the ALH
dai_index during the BE DAI hw_params in the dai_index field of struct
ipc4_copier and use that to set the device ID in the configuration blob.
This will avoid errors during copier init after an xrun.
Note that the dai_index is typically set in topology for DMIC/SSP, but
it's not used for ALH. Reclaiming this dai_index field to store the
node_id does not generate a conflict with topology-defined values.
ASoC: SOF: pcm: reset all PCM sources in case of xruns
With the delayed stops, the xrun handling is problematic: the
applications expects everything to be reset but the firmware and DMA
are still in a PAUSED state.
This patch makes sure the prepare while pending_stop is set is
special-cased.
Add a state variable to keep track of delayed stops, in case
pcm_ops->platform_stop_during_hw_free is set.
This patch should be iso-functionality, possibly removing no-op
cases. The main purpose of this new state variable is to prepare a
follow-up patch to reset all PCM and DMAs in case of stop/prepare xrun
sequences.
ASoC: SOF: Intel: hda: Clear Soundwire node ID during BE DAI hw_free
When an xrun happens, the BE DAI hw_params doesn't get invoked before
the stream restarts with a prepare. In this case, clearing the node ID
when the DAI widget is freed and unprepared will result in an error when
it is re-initialized. In order to avoid this, move the code to clear the
node ID to the BE DAI hw_free op to keep it balanced with the BE DAI
hw_params.
ASoC: SOF: Intel: hda-dai: set dma_stream_channel_map device
sof_ipc4_dma_config_tlv{} is required for ACE2.x. The patch follow the
convention to set the dma_stream_channel_map.mapping device as
"link_id << 8 | pdi_id".
And the mapping in sof_ipc4_alh_configuration_blob{} should be the same
as dma_stream_channel_map.mapping in sof_ipc4_dma_config{}.
The purposes of device id is to map DMA tlv.
The SoundWire aggregated solution was to use one DMA on multiple links.
But, the solution changed to use one DMA for each link. It means that
we should assign HDaudio stream_tag for each cpu_dai.
The existing code derives the channel map used to program the HDaudio
link DMA from the hw_params, but that is not quite right in the case
of aggregation. The code in soc-pcm.c splits the hw_params depending
on the codec_ch_map, and we need to reconstruct the channel-map to
insert the data in the right places.
This issue is seen only on amplifier feedback capture where the data
from the second amplifier was replaced by that of the first amplifier.
Note that the loop iterator of the macro for_each_rtd_cpu_dais() is
reused in a following loop. This is different to all existing usages
of that macro, hence the use of a boolean flag to avoid an access to
an uninitialized variable.

as an integer type, the left shift operation will wraparound and set
mask to 0 instead of all 1's. In order to fix this, we type cast 1 as
