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_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. When selected, the probe is handled in two steps, for example to avoid lockdeps if request_module is used in the probe. # Supported IPC versions config SND_SOC_SOF_IPC3 bool config SND_SOC_SOF_INTEL_IPC4 bool source "sound/soc/sof/amd/Kconfig" source "sound/soc/sof/imx/Kconfig" source "sound/soc/sof/intel/Kconfig" source "sound/soc/sof/mediatek/Kconfig" source "sound/soc/sof/xtensa/Kconfig" endif
