config SND_SOC_SOF_TOPLEVEL bool "Sound Open Firmware Support" help This adds support for Sound Open Firmware (SOF). SOF is a 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 tristate "SOF PCI enumeration support" depends on PCI select SND_SOC_SOF select SND_SOC_ACPI if ACPI select SND_SOC_SOF_OPTIONS select SND_SOC_SOF_INTEL_PCI if SND_SOC_SOF_INTEL_TOPLEVEL help This adds support for PCI enumeration.

This option is required to enable Intel Haswell/Broadwell/Baytrail/Cherrytrail devices Say Y if you need this option If unsure select "N". config SND_SOC_SOF_OPTIONS tristate help This option is not user-selectable but automagically handled by 'select' statements at a higher level if SND_SOC_SOF_OPTIONS config SND_SOC_SOF_NOCODEC tristate config SND_SOC_SOF_NOCODEC_SUPPORT bool "SOF nocodec 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 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_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 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. If unsure, select "N". endif ## SND_SOC_SOF_DEBUG endif ## SND_SOC_SOF_OPTIONS config SND_SOC_SOF tristate select SND_SOC_TOPOLOGY select SND_SOC_SOF_NOCODEC if SND_SOC_SOF_NOCODEC_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. source "sound/soc/sof/intel/Kconfig" source "sound/soc/sof/xtensa/Kconfig" endif
