ASoC: SOF: build compression interface into snd_sof.ko

2021-11-12T21:25:18+00:00

With CONFIG_SND_SOC_SOF_COMPRESS=m, the compression code is
not built into a the main SOF driver when that is built-in:

x86_64-linux-ld: sound/soc/sof/ipc.o: in function `ipc_stream_message':
ipc.c:(.text+0x5a2): undefined reference to `snd_sof_compr_fragment_elapsed'
x86_64-linux-ld: sound/soc/sof/topology.o: in function `sof_dai_load':
topology.c:(.text+0x32d1): undefined reference to `snd_sof_compr_init_elapsed_work'
x86_64-linux-ld: topology.c:(.text+0x32e1): undefined reference to `snd_sof_compr_init_elapsed_work'

Make this a 'bool' symbol so it just decides whether the
code gets built at all.

ASoC: SOF: Introduce fragment elapsed notification API

2021-10-07T15:57:57+00:00

This patch prepares the introduction of the compress API with SOF.

After each fragment is accepted by the DSP we need to inform
the userspace applications that they can send the next fragment.
This is done via snd_compr_fragment_elapsed.

Similar with the PCM case, in order to avoid sending an IPC before
the previous IPC is handled we need to schedule a delayed work to
call snd_compr_fragment_elapsed().

See snd_sof_pcm_period_elapsed.

To sum up this patch offers the following API to SOF code:
	* snd_sof_compr_init_elapsed_work
	* snd_sof_compr_fragment_elapsed

Note that implementation for compressed function is in a new file
selected via CONFIG_SND_SOC_SOF_COMPRESS invisible config option.
This option is automatically selected for platforms that support
the compress interface. For now only i.MX8 platforms support this.

For symmetry we introduce snd_sof_pcm_init_elapsed_work to setup
the work struct for PCM case.

ASoC: SOF: Change SND_SOC_SOF_TOPLEVEL from config to menuconfig

2021-09-30T12:26:03+00:00

We have growing number of options under SND_SOC_SOF_TOPLEVEL as SOF
adaptation is growing (Intel, NXP, AMD and Mediatek) and new features are
added.
It will make the menuconfig user experience much cleaner if we move the
SOF options under a separate page.

ASoC: SOF: add Kconfig option for probe workqueues

2021-04-12T16:05:50+00:00

The probe workqueue is currently used in the HDaudio case, following
the example of the snd-hda-intel driver.

For development and validation, it's useful to enable the probe
workqueue even with ACPI devices or NOCODEC mode.

ASoC: SOF: pci: split PCI into different drivers

2021-03-02T14:32:00+00:00

Move PCI IDs and device-specific definitions out of common code. No
functionality change for now, just code split and removal of
IF_ENABLED() which made the configurations too complicated in case of
reuse of IP across generations.

Additional changes to address the DSP_CONFIG case and SoundWire
depends/select confusions are provided in follow-up patches.

ASoC: SOF: ACPI: avoid reverse module dependency

2021-03-02T14:31:40+00:00

The SOF-ACPI driver is backwards from the normal Linux model, it has a
generic driver that knows about all the specific drivers, as opposed to
having hardware specific drivers that link against a common framework.

This requires ugly Kconfig magic and leads to missed dependencies as
seen in this link error:

arm-linux-gnueabi-ld: sound/soc/sof/sof-pci-dev.o: in function `sof_acpi_probe':
sof-pci-dev.c:(.text+0x1c): undefined reference to `snd_intel_dsp_driver_probe'

Change it to use the normal probe order of starting with a specific
device in a driver, turning the sof-acpi-dev.c driver into a
library (exported symbols are name-spaced to avoid symbol pollution).

For backwards-compatibility with previous Kconfigs, the default values
for platform drivers uses the top-level ACPI configurations. The
modules were also renamed to allow for gradual transitions in test
scripts.

ASoC: SOF: Generic probe compress operations

2020-02-18T21:52:07+00:00

Define system-agnostic probe compress flow which serves as a base for
actual, hardware-dependent implementations.
As per firmware spec, maximum of one extraction stream is allowed, while
for injection, there can be plenty.

Apart from probe_pointer, all probe compress operations are mandatory.
Copy operation is defined as unified as its flow should be shared across
all SOF systems.
