SOF is free and	  generic open source audio DSP firmware for multiple devices.	  Say Y if you have such a device that is supported by SOF.	  If unsure select "N". if SND_SOC_SOF_TOPLEVEL config SND_SOC_SOF_PCI_DEV	tristate config SND_SOC_SOF_PCI	tristate "SOF PCI enumeration support"	depends on PCI	help	  This adds support for PCI enumeration. This option is	  required to enable Intel Skylake+ devices.	  For backwards-compatibility with previous configurations the selection will	  be used as default for platform-specific drivers.	  Say Y if you need this option.	  If unsure select "N". config SND_SOC_SOF_ACPI	tristate "SOF ACPI enumeration support"	depends on ACPI || COMPILE_TEST	help	  This adds support for ACPI enumeration. This option is required	  to enable Intel Broadwell/Baytrail/Cherrytrail devices.	  For backwards-compatibility with previous configurations the selection will	  be used as default for platform-specific drivers.	  Say Y if you need this option.	  If unsure select "N". config SND_SOC_SOF_ACPI_DEV	tristate config SND_SOC_SOF_OF	tristate "SOF OF enumeration support"	depends on OF	help	  This adds support for Device Tree enumeration. This option is	  required to enable i.MX8 or Mediatek devices.	  Say Y if you need this option. If unsure select "N". config SND_SOC_SOF_OF_DEV	tristate config SND_SOC_SOF_COMPRESS	bool	select SND_SOC_COMPRESS config SND_SOC_SOF_DEBUG_PROBES	tristate	select SND_SOC_SOF_CLIENT	select SND_SOC_COMPRESS	help	  This option enables the data probing feature that can be used to	  gather data directly from specific points of the audio pipeline.	  This option is not user-selectable but automagically handled by	  'select' statements at a higher level. config SND_SOC_SOF_CLIENT	tristate	select AUXILIARY_BUS	help	  This option is not user-selectable but automagically handled by	  'select' statements at a higher level. config SND_SOC_SOF_DEVELOPER_SUPPORT	bool "SOF developer options support"	depends on EXPERT && SND_SOC_SOF	help	  This option unlocks SOF developer options for debug/performance/	  code hardening.	  Distributions should not select this option, only SOF development	  teams should select it.	  Say Y if you are involved in SOF development and need this option.	  If not, select N. if SND_SOC_SOF_DEVELOPER_SUPPORT config SND_SOC_SOF_FORCE_PROBE_WORKQUEUE	bool "SOF force probe workqueue"	select SND_SOC_SOF_PROBE_WORK_QUEUE	help	  This option forces the use of a probe workqueue, which is only used	  when HDaudio is enabled due to module dependencies. Forcing this	  option is intended for debug only, but this should not add any	  functional issues in nominal cases.	  Say Y if you are involved in SOF development and need this option.	  If not, select N. config SND_SOC_SOF_NOCODEC	tristate config SND_SOC_SOF_NOCODEC_SUPPORT	bool "SOF nocodec static mode support"	help	  This adds support for a dummy/nocodec machine driver fallback	  option if no known codec is detected. This is typically only	  enabled for developers or devices where the sound card is	  controlled externally.	  This option is mutually exclusive at build time with the Intel HDAudio support.	  Selecting it may have negative impacts and prevent e.g. microphone	  functionality from being enabled on Intel CoffeeLake and later	  platforms.	  Distributions should not select this option!	  Say Y if you need this nocodec fallback option.	  If unsure select "N". config SND_SOC_SOF_STRICT_ABI_CHECKS	bool "SOF strict ABI checks"	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". config SND_SOC_SOF_ALLOW_FALLBACK_TO_NEWER_IPC_VERSION	bool "SOF allow fallback to newer IPC version"	help	  This option will allow the kernel to try to 'fallback' to a newer IPC	  version if there are missing firmware files to satisfy the default IPC	  version.	  IPC version fallback to older versions is not affected by this option,	  it is always available.	  Say Y if you are involved in SOF development and need this option.	  If not, select N. config SND_SOC_SOF_DEBUG	bool "SOF debugging features"	help	  This option can be used to enable or disable individual SOF firmware	  and driver debugging options.	  Say Y if you are debugging SOF FW or drivers.	  If unsure select "N". if SND_SOC_SOF_DEBUG config SND_SOC_SOF_NOCODEC_DEBUG_SUPPORT	bool "SOF nocodec debug mode support"	depends on !SND_SOC_SOF_NOCODEC_SUPPORT	help	  This adds support for a dummy/nocodec machine driver fallback	  option.	  Unlike the SND_SOC_SOF_NOCODEC_SUPPORT, this option is NOT	  mutually exclusive at build with the Intel HDAudio support. The	  selection will be done depending on command line or modprobe.d settings	  Distributions should not select this option!	  Say Y if you need this nocodec debug fallback option.	  If unsure select "N". config SND_SOC_SOF_FORCE_NOCODEC_MODE	bool "SOF force nocodec Mode"	depends on SND_SOC_SOF_NOCODEC_SUPPORT	help	  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.	  Say Y if you need this force nocodec mode option.	  If unsure select "N". config SND_SOC_SOF_DEBUG_XRUN_STOP	bool "SOF stop on XRUN"	help	  This option forces PCMs to stop on any XRUN event. This is useful to	  preserve any trace data and 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 forces 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.	  If unsure, select "N". config SND_SOC_SOF_DEBUG_ENABLE_FIRMWARE_TRACE	bool "SOF enable firmware trace"	help	  The firmware trace can be enabled either at build-time with	  this option, or dynamically by setting flags in the SOF core	  module parameter (similar to dynamic debug).	  If unsure, select "N". config SND_SOC_SOF_DEBUG_IPC_FLOOD_TEST	tristate "SOF enable IPC flood test"	depends on SND_SOC_SOF	select SND_SOC_SOF_CLIENT	help	  This option enables a separate client device for IPC flood test	  which can be used to flood the DSP with test IPCs and gather stats	  about response times.	  Say Y if you want to enable IPC flood test.	  If unsure, select "N". config SND_SOC_SOF_DEBUG_IPC_FLOOD_TEST_NUM	int "Number of IPC flood test clients"	range 1 32	default 2	depends on SND_SOC_SOF_DEBUG_IPC_FLOOD_TEST	help	  Select the number of IPC flood test clients to be created. config SND_SOC_SOF_DEBUG_IPC_MSG_INJECTOR	tristate "SOF enable IPC message injector"	depends on SND_SOC_SOF	select SND_SOC_SOF_CLIENT	help	  This option enables the IPC message injector which can be used to send	  crafted IPC messages to the DSP to test its robustness.	  Say Y if you want to enable the IPC message injector.	  If unsure, select "N". config SND_SOC_SOF_DEBUG_IPC_KERNEL_INJECTOR	tristate "SOF enable IPC kernel injector"	depends on SND_SOC_SOF	select SND_SOC_SOF_CLIENT	help	  This option enables the IPC kernel injector which can be used to send	  crafted IPC messages to the kernel to test its robustness against	  DSP messages.	  Say Y if you want to enable the IPC kernel injector.	  If unsure, select "N". config SND_SOC_SOF_DEBUG_RETAIN_DSP_CONTEXT	bool "SOF retain DSP context on any FW exceptions"	help	  This option keeps the DSP in D0 state so that firmware debug	  information can be retained and dumped to userspace.	  Say Y if you want to retain DSP context for FW exceptions.	  If unsure, select "N". endif ## SND_SOC_SOF_DEBUG endif ## SND_SOC_SOF_DEVELOPER_SUPPORT config SND_SOC_SOF	tristate	select SND_SOC_TOPOLOGY	select SND_SOC_SOF_NOCODEC if SND_SOC_SOF_NOCODEC_SUPPORT	select SND_SOC_SOF_NOCODEC if SND_SOC_SOF_NOCODEC_DEBUG_SUPPORT	help	  This option is not user-selectable but automagically handled by	  'select' statements at a higher level.	  The selection is made at the top level and does not exactly follow	  module dependencies but since the module or built-in type is decided	  at the top level it doesn't matter. config SND_SOC_SOF_PROBE_WORK_QUEUE	bool	help	  This option is not user-selectable but automagically handled by	  'select' statements at a higher level.
