[PATCH 00/20] ASoC: SOF: Intel: add LunarLake support

[Pierre-Louis Bossart]

IMPORTANT NOTE: this patchset is dependent on Takashi's hda-intel-6.6
tag. The PCI parts will not compile without merging this tag into the
ASoC tree.

This patchset first fixes a number of errors made in the hda-mlink
support, then adds Lunar Lake definitions. The main contribution is
the hda-dai changes where the HDaudio DMA is now used for SSP, DMIC
and SoundWire. In previous hardware the GPDMA (aka DesignWare) was
used and controlled by the audio firmware. The volume of code is
minimized with the abstraction added in previous kernel cycles.

Due to cross-dependencies between ASoC and SoundWire trees, the full
support for jack detection will be deferred to the next kernel
cycle. There's not much point to ask for a sync of the two trees to
support one patch for each tree - we are at -rc5 already.

[PATCH 01/20] ASoC: SOF: Intel: hda-mlink: fix off-by-one error

[Pierre-Louis Bossart]

The HCHAN parameter should be the highest channel number, not the
channel count.

While we're at it, handle LCHAN with the dual __ffs helper.

    ASoC: SOF: Intel: hda-mlink: program SoundWire LSDIID registers

    Each SoundWire peripheral can be programmed from the manager side
    either with a regular command FIFO, or with the HDaudio CORB/RIRB
    DMA-based mechanism. The mapping between SoundWire peripheral and SDI
    address is handled with the LSDIID register.

    This mapping only works of course if each peripheral has a unique
    address across all links. This has already been enforced in previous
    Intel contributions allowing for an IDA-based solution for the device
    number allocation.

    The checks on the dev_num are handled at the SoundWire level, but the
    locking is handled at the hda-mlink level.

[PATCH 03/20] ASoC: SOF: ipc4: avoid uninitialized default instance 0

[Pierre-Louis Bossart]

From: Ranjani Sridharan <ranjani.sridharan@linux.intel.com>

When a pipeline contains multiple DAI widgets, the pipe_widget is not
set up except for the first DAI. This result in the pipe_widget having
a default instance 0, which can conflict with another real the
pipeline instance 0 and leads to spurious transitions.

This patch makes sure the instance_id is properly initialized to a
-EINVAL value.

[PATCH 04/20] ASoC: SOF: ipc4-topology: restore gateway config length

[Pierre-Louis Bossart]

The initial code had a logic flaw where the gateway config length kept
increasing after each playback/capture trigger, with the DMA config
TLV being added at every call of sof_ipc4_prepare_copier_module()

This didn't cause any issues with regular playback/capture, but this
was flagged as an error by firmware in the case of multiple amplifiers
on different links.

[PATCH 07/20] ASoC: SOF: Intel: split MTL and LNL operations

[Pierre-Louis Bossart]

It was just a matter of time before we found a case where we needed
separate ops for MTL and LNL. For LNL we need to set the DMIC/SSP
OFLEN bit in the probe and resume steps, and this can only be done
cleanly with separate ops.

The function prototypes in mtl.h were added in the same order as their
implementation in mtl.c.

[PATCH 08/20] ASoC: SOF: Intel: LNL: enable DMIC/SSP offload in probe/resume

[Pierre-Louis Bossart]

In the LunarLake hardware, the default IP ownership changed to the
host driver, instead of the firmware in previous generation.

In the absence of any capability negotiation, we need to assume a
fixed partitioning between host driver and firmware. The OFLEN bit
needs to be set as early as possible for resources handled by the
firmware, since we can't control when the firmware might try to access
the resources.

For now DMIC and SSP are handled by the DSP firmware. SoundWire is a
separate case, the OFLEN bit can be set when starting-up and resuming
the aux device for each link.

[PATCH 09/20] ASoC: SOF: Intel: hda-dai-ops: add/select DMA ops for SSP

[Pierre-Louis Bossart]

The DMA widget ops are almost similar to the HDaudio ones, with the
exception of codec_dai_set_hext_stream() which is not relevant and the
format calculation which isn't dependent on the codec dai.

The DMA ops can be selected only starting with ACE_2_0.

[PATCH 12/20] ASoC: SOF: Intel: hda-dai-ops: only allocate/release streams for first CPU DAI

[Pierre-Louis Bossart]

When we have multiple CPU DAIs in a dailink, typically for SoundWire
aggregated solutions with amplifiers on multiple links, we only want
to allocate one HDaudio stream_tag. The simplest solution is to
allocate the hext_stream/stream_tag for the DAI with index 0 in the
dailink, and reuse the same stream for all other CPU DAIs.

This assumption relies on serialization of DAIs by the ASoC core,
where all CPU DAIs are handled in a loop.

The stream release follows the same idea of releasing the tag for the
first DAI only. Ideally we would want the loop to be handled in
reverse-order to summetry, but there is no risk of reusing a
stream_tag which is no longer valid.

[PATCH 16/20] ASoC: SOF: Intel: add abstraction for SoundWire wake-ups

[Pierre-Louis Bossart]

The existing code cannot work for LunarLake, let's add a layer of
abstraction.

No functional change in this patch.

[PATCH 18/20] ASoC: SOF: Intel: hda-dai-ops: reset device count for SoundWire DAIs

[Pierre-Louis Bossart]

The solution used before LunarLake relies on a 'Multi-gateway'
firmware configuration. This is no longer needed with the DMA hardware
handling multiple links directly. To avoid adding a platform-specific
quirk in the generic IPC4 code, this patch resets the device count
when fetching the stream context.

[PATCH 19/20] ASoC: SOF: IPC4: clarify 'pipeline_ids' usage and logs

[Pierre-Louis Bossart]

A pipeline is identified by two indices: 'instance_id' and 'pipeline_id'

This is clearly seen in kernel logs when creating a pipeline

"Create widget pipeline.20 instance 0 - pipe 20 - core 0"

but other logs are less clear

"ipc4 set pipeline 1 state 4"

Change definitions and logs to make sure the logs clearly identify
which of the two indices are used in state transitions.

No functional change.

[PATCH 20/20] ASoC: SOF: Intel: hda-mlink: add sublink to dev_dbg() log

[Pierre-Louis Bossart]

When using more than one sublink for amplifier aggregation, we need to
add the sublink info to debug the programming sequences.

No functional change, only additional precisions in the log.

All being well this means that it will be integrated into the linux-next
tree (usually sometime in the next 24 hours) and sent to Linus during
the next merge window (or sooner if it is a bug fix), however if
problems are discovered then the patch may be dropped or reverted.

You may get further e-mails resulting from automated or manual testing
and review of the tree, please engage with people reporting problems and
send followup patches addressing any issues that are reported if needed.

If any updates are required or you are submitting further changes they
should be sent as incremental updates against current git, existing
patches will not be replaced.

Please add any relevant lists and maintainers to the CCs when replying
to this mail.

Thanks,
Mark
