  54           option if no known codec is detected. This is typically only
  55           enabled for developers or devices where the sound card is

  64           files.
  65           When these files are more recent than the kernel, the kernel
  66           will handle the functionality it supports and may report errors
  67           during topology creation or run-time usage if new functionality
  68           is invoked.
  69           This option will stop topology creation and firmware load upfront.
  70           It is intended for SOF CI/releases and not for users or distros.
  71           Say Y if you want strict ABI checks for an SOF release

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

  91           typically only enabled for developers for debug purposes, before

 117           elapse to inform ALSA about that, on platforms (e.g. Intel SKL+) that
 118           with other approach (e.g. HDAC DPIB/posbuf) to elapse PCM.
 119           On platforms (e.g. Intel SKL-) where position update IPC is the only
 120           one choice, this setting won't impact anything.

 129           memory -> DSP resource (memory, register, etc)
 130           before the audio DSP is suspended. This will increase the suspend
 131           latency and therefore should be used for debug purposes only.
 132           Say Y if you want to enable caching the memory windows.
