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.

This adds support for a dummy/nocodec machine driver fallback

option if no known codec is detected. This is typically only

enabled for developers or devices where the sound card is

|
controlled externally.
|

This option is mutually exclusive with the Intel HDAudio support.

Selecting it may have negative impacts and prevent e.g. microphone

functionality from being enabled on Intel CoffeeLake and later

platforms.

help
|

This option enables strict ABI checks for firmware and topology
|
|
files.
|
|
When these files are more recent than the kernel, the kernel
|
|
will handle the functionality it supports and may report errors
|
|
during topology creation or run-time usage if new functionality

is invoked.
|

This option will stop topology creation and firmware load upfront.

It is intended for SOF CI/releases and not for users or distros.

This forces SOF to use dummy/nocodec as machine driver, even

though there is a codec detected on the real platform. This is

typically only enabled for developers for debug purposes, before

codec/machine driver is ready, or to exclude the impact of those

This option enables more verbose IPC logs, with command types in

This option forces to handle stream position update IPCs and run PCM

elapse to inform ALSA about that, on platforms (e.g. Intel SKL+) that
|
|
with other approach (e.g. HDAC DPIB/posbuf) to elapse PCM.
|

On platforms (e.g. Intel SKL-) where position update IPC is the only

|
one choice, this setting won't impact anything.

This option enables caching of debugfs

latency and therefore should be used for debug purposes only.
