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
help
This adds support for PCI enumeration. This option is
required to enable Intel Skylake+ devices
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
select SND_SOC_SOF
select SND_SOC_ACPI if ACPI
select IOSF_MBI if X86 && PCI
help
This adds support for ACPI enumeration. This option is required
to enable Intel Broadwell/Baytrail/Cherrytrail devices
Say Y if you need this option
If unsure select "N".
config SND_SOC_SOF_OF
tristate "SOF OF enumeration support"
depends on OF || COMPILE_TEST
select SND_SOC_SOF
help
This adds support for Device Tree enumeration. This option is
required to enable i.MX8 devices.
Say Y if you need this option. If unsure select "N".
config SND_SOC_SOF_DEBUG_PROBES
bool "SOF enable data probing"
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.
Say Y if you want to enable probes.
If unsure, select "N".
config SND_SOC_SOF_DEVELOPER_SUPPORT
bool "SOF developer options support"
depends on EXPERT
help
This option unlock 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_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
This option is mutually exclusive 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_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".
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
bool "SOF enable IPC flood test"
help
This option enables the 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_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".

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.
