|
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_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

|
If unsure, select "N".
|

config SND_SOC_SOF_DEBUG_RETAIN_DSP_CONTEXT

This option keeps the DSP in D0 state so that firmware debug

information can be retained and dumped to userspace.
