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.

Say Y if you want strict ABI checks for an SOF release
|
|
If you are not involved in SOF releases and CI development
|

select "N".

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

drivers

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

human-readable form instead of just 32-bit hex dumps. This is useful

This option force 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.

if you are trying to debug pointer update with position IPCs or where

DPIB/posbuf is not ready, select "Y".

help
|
|
This option enables caching of debugfs
|
|
memory -> DSP resource (memory, register, etc)
|
|
before the audio DSP is suspended. This will increase the suspend
|
|
latency and therefore should be used for debug purposes only.

Say Y if you want to enable caching the memory windows.

If unsure, select "N".
