ASoC: SOF: Kconfig: Make SND_SOC_SOF_HDA_PROBES tristate

2022-04-19T15:30:31+00:00

SND_SOC_SOF_HDA_PROBES must be tristate because the code it builds
depends on code that is tristate.

If SND_SOC_SOF_HDA_PROBES is bool it leads to the following build
inconsistency:

SND_SOC_SOF_HDA_COMMON=m
  which selects SND_SOC_SOF_HDA_PROBES
    but since this is a bool SND_SOC_SOF_HDA_PROBES=y

SND_SOC_SOF_HDA_PROBES=y
  selects SND_SOC_SOF_DEBUG_PROBES=y
    so sof-client-probes.c is built into the kernel.

sof-client-probes.c calls functions in sof-client.c, but

SND_SOC_SOF=m
  sof-client.c is built into a loadable module.

ASoC: SOF: Intel: Fix build error without SND_SOC_SOF_PCI_DEV

If SND_SOC_SOF_PCI_DEV is n, bulding fails:

Make SND_SOC_SOF_MERRIFIELD select SND_SOC_SOF_PCI_DEV to fix this.

ASoC: SOF: Convert the generic probe support to SOF client

2022-02-10T15:19:12+00:00

Add a new client driver for probes support and move
all the probes-related code from the core to the
client driver.

The probes client driver registers a component driver
with one CPU DAI driver for extraction and creates a
new sound card with one DUMMY DAI link with a dummy codec
that will be used for extracting audio data from specific
points in the audio pipeline.

The probes debugfs ops are based on the initial
implementation by Cezary Rojewski and have been moved
out of the SOF core into the client driver making it
easier to maintain. This change will make it easier
for the probes functionality to be added for all platforms
without having the need to modify the existing(15+) machine
drivers.

ASoC: SOF: Intel: make DMI L1 selection more robust

2021-08-13T12:16:16+00:00

Exposing the DMI L1 configuration as a kernel Kconfig option was in
hindsight a really bad idea. It led to several errors reported by
distributions which selected it by mistake.

The Kconfig is now replaced with a kernel parameter. Since DMI L1
entry is incompatible with pause on a capture stream, the latter is
disabled when the kernel parameter is set.

Experimental results show an increased residency in higher C states
and a significant decrease of system power consumption for "work from
home" usages such as VoIP calls.

ASoC: SOF: Intel: Kconfig: fix SoundWire dependencies

2021-08-03T00:44:58+00:00

The previous Kconfig cleanup added simplifications but also introduced
a new one by moving a boolean to a tristate. This leads to randconfig
problems.

This patch moves the select operations in the SOUNDWIRE_LINK_BASELINE
option. The INTEL_SOUNDWIRE config remains a tristate for backwards
compatibility with older configurations but is essentially an on/off
switch.

ALSA: hda: move Intel SoundWire ACPI scan to dedicated module

2021-03-02T14:33:00+00:00

The ACPI scan capabilities is called from the intel-dspconfig as well
as the SOF/HDaudio drivers. This creates dependencies and randconfig issues
when HDaudio and SOF/SoundWire are not all configured as modules.

To simplify Kconfig dependencies between HDAudio, SoundWire, SOF and
intel-dspconfig, move the ACPI scan helpers to a dedicated
module. This follows the same idea as NHLT helpers which are already
handled as a dedicated module.

The only functional change is that the kernel parameter to filter
links is now handled by a different module, but that was only provided
for developers needing work-arounds for early BIOS releases.

ASoC: SOF: Intel: SoundWire: simplify Kconfig

2021-03-02T14:32:43+00:00

The Kconfig file is way too convoluted. Track platforms where
SoundWire is supported, and add simpler conditions to make sure there
is no module/built-in issue.

The use of 'depends on' is less intuitive if a required 'depend' is
missing, but that's a small price to pay for clarity and simplicity.

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.
