93	  option if no known codec is detected. This is typically only
94	  enabled for developers or devices where the sound card is
95	  controlled externally.
96	  This option is mutually exclusive with the Intel HDAudio support.
97	  Selecting it may have negative impacts and prevent e.g. microphone
98	  functionality from being enabled on Intel CoffeeLake and later

106	help
107	  This option enables strict ABI checks for firmware and topology
108	  files.
109	  When these files are more recent than the kernel, the kernel
110	  will handle the functionality it supports and may report errors
111	  during topology creation or run-time usage if new functionality
112	  is invoked.
113	  This option will stop topology creation and firmware load upfront.
114	  It is intended for SOF CI/releases and not for users or distros.

133	  This forces SOF to use dummy/nocodec as machine driver, even
134	  though there is a codec detected on the real platform. This is
135	  typically only enabled for developers for debug purposes, before
136	  codec/machine driver is ready, or to exclude the impact of those
137	  drivers.

152	  This option enables more verbose IPC logs, with command types in
153	  human-readable form instead of just 32-bit hex dumps. This is useful
154	  if you are trying to debug IPC with the DSP firmware.

160	  This option forces to handle stream position update IPCs and run PCM
161	  elapse to inform ALSA about that, on platforms (e.g. Intel SKL+) that
162	  with other approach (e.g. HDAC DPIB/posbuf) to elapse PCM.
163	  On platforms (e.g. Intel SKL-) where position update IPC is the only
164	  one choice, this setting won't impact anything.
165	  If you are trying to debug pointer update with position IPCs or where
166	  DPIB/posbuf is not ready, select "Y".

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

182	  The firmware trace can be enabled either at build-time with
183	  this option, or dynamically by setting flags in the SOF core
184	  module parameter (similar to dynamic debug).
185	  If unsure, select "N".
