103	  option if no known codec is detected. This is typically only
104	  enabled for developers or devices where the sound card is
105	  controlled externally.
106	  This option is mutually exclusive with the Intel HDAudio support.
107	  Selecting it may have negative impacts and prevent e.g. microphone
108	  functionality from being enabled on Intel CoffeeLake and later

117	  This option enables strict ABI checks for firmware and topology
118	  files.
119	  When these files are more recent than the kernel, the kernel
120	  will handle the functionality it supports and may report errors
121	  during topology creation or run-time usage if new functionality
122	  is invoked.
123	  This option will stop topology creation and firmware load upfront.
124	  It is intended for SOF CI/releases and not for users or distros.

142	help
143	  This forces SOF to use dummy/nocodec as machine driver, even
144	  though there is a codec detected on the real platform. This is
145	  typically only enabled for developers for debug purposes, before
146	  codec/machine driver is ready, or to exclude the impact of those
147	  drivers.

160	bool "SOF verbose IPC logs"
161	help
162	  This option enables more verbose IPC logs, with command types in
163	  human-readable form instead of just 32-bit hex dumps. This is useful
164	  if you are trying to debug IPC with the DSP firmware.
165	  If unsure select "N".

167config SND_SOC_SOF_DEBUG_FORCE_IPC_POSITION
168	bool "SOF force to use IPC for position update on SKL+"
169	help
170	  This option forces to handle stream position update IPCs and run PCM
171	  elapse to inform ALSA about that, on platforms (e.g. Intel SKL+) that
172	  with other approach (e.g. HDAC DPIB/posbuf) to elapse PCM.
173	  On platforms (e.g. Intel SKL-) where position update IPC is the only
174	  one choice, this setting won't impact anything.
175	  If you are trying to debug pointer update with position IPCs or where
176	  DPIB/posbuf is not ready, select "Y".

178
179config SND_SOC_SOF_DEBUG_ENABLE_DEBUGFS_CACHE
180	bool "SOF enable debugfs caching"
181	help
182	  This option enables caching of debugfs
183	  memory -> DSP resource (memory, register, etc)
184	  before the audio DSP is suspended. This will increase the suspend
185	  latency and therefore should be used for debug purposes only.
186	  Say Y if you want to enable caching the memory windows.
187	  If unsure, select "N".
188

192	  The firmware trace can be enabled either at build-time with
193	  this option, or dynamically by setting flags in the SOF core
194	  module parameter (similar to dynamic debug).

201	  This option enables a separate client device for IPC flood test
202	  which can be used to flood the DSP with test IPCs and gather stats
203	  about response times.
