+	  enabled for developers or devices where the sound card is
+	  controlled externally
+	  Say Y if you need this nocodec fallback option
+	  If unsure select "N".
+
+config SND_SOC_SOF_DEBUG
+	bool "SOF debugging features"

+	  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
+	  Say Y if you need this force nocodec mode option
+	  If unsure select "N".
+
+config SND_SOC_SOF_DEBUG_XRUN_STOP

+	help
+	  This option forces PCMs to stop on any XRUN event. This is useful to
+	  preserve any trace data ond pipeline status prior to the XRUN.
+	  Say Y if you are debugging SOF FW pipeline XRUNs.
+	  If unsure select "N".
+
+config SND_SOC_SOF_DEBUG_VERBOSE_IPC
+	bool "SOF verbose IPC logs"
+	help
+	  This option enables more verbose IPC logs, with command types in
+	  human-readable form instead of just 32-bit hex dumps. This is useful
+	  if you are trying to debug IPC with the DSP firmware.
+	  If unsure select "N".
+
+config SND_SOC_SOF_DEBUG_FORCE_IPC_POSITION
+	bool "SOF force to use IPC for position update on SKL+"
+	help
+	  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".
+	  If unsure select "N".
+
+config SND_SOC_SOF_DEBUG_ENABLE_DEBUGFS_CACHE
+	bool "SOF enable debugfs caching"
+	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.
