| 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. |

| 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 |

| config SND_SOC_SOF_NOCODEC_DEBUG_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! |

| |
| 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". |

| which can be used to flood the DSP with test IPCs and gather stats |
| about response times. |
