5	  This adds support for Sound Open Firmware (SOF). SOF is free and
6	  generic open source audio DSP firmware for multiple devices.
7	  Say Y if you have such a device that is supported by SOF.

78	help
79	  This option forces the use of a probe workqueue, which is only used
80	  when HDaudio is enabled due to module dependencies. Forcing this
81	  option is intended for debug only, but this should not add any
82	  functional issues in nominal cases.

92	  This adds support for a dummy/nocodec machine driver fallback
93	  option if no known codec is detected. This is typically only
94	  enabled for developers or devices where the sound card is
95	  controlled externally.
96	  This option is mutually exclusive with the Intel HDAudio support.
97	  Selecting it may have negative impacts and prevent e.g. microphone
98	  functionality from being enabled on Intel CoffeeLake and later
99	  platforms.
100	  Distributions should not select this option!
101	  Say Y if you need this nocodec fallback option.
102	  If unsure select "N".
103
104config SND_SOC_SOF_STRICT_ABI_CHECKS
105	bool "SOF strict ABI checks"
106	help
107	  This option enables strict ABI checks for firmware and topology
108	  files.
109	  When these files are more recent than the kernel, the kernel
110	  will handle the functionality it supports and may report errors
111	  during topology creation or run-time usage if new functionality
112	  is invoked.
113	  This option will stop topology creation and firmware load upfront.
114	  It is intended for SOF CI/releases and not for users or distros.
115	  Say Y if you want strict ABI checks for an SOF release.
116	  If you are not involved in SOF releases and CI development,
117	  select "N".

122	  This option can be used to enable or disable individual SOF firmware

130	bool "SOF force nocodec Mode"
131	depends on SND_SOC_SOF_NOCODEC_SUPPORT
132	help
133	  This forces SOF to use dummy/nocodec as machine driver, even
134	  though there is a codec detected on the real platform. This is
135	  typically only enabled for developers for debug purposes, before
136	  codec/machine driver is ready, or to exclude the impact of those
137	  drivers.
138	  Say Y if you need this force nocodec mode option.
139	  If unsure select "N".

141config SND_SOC_SOF_DEBUG_XRUN_STOP
142	bool "SOF stop on XRUN"
143	help
144	  This option forces PCMs to stop on any XRUN event. This is useful to
145	  preserve any trace data and pipeline status prior to the XRUN.
146	  Say Y if you are debugging SOF FW pipeline XRUNs.
147	  If unsure select "N".
148
149config SND_SOC_SOF_DEBUG_VERBOSE_IPC
150	bool "SOF verbose IPC logs"
151	help
152	  This option enables more verbose IPC logs, with command types in
153	  human-readable form instead of just 32-bit hex dumps. This is useful
154	  if you are trying to debug IPC with the DSP firmware.
155	  If unsure select "N".
156
157config SND_SOC_SOF_DEBUG_FORCE_IPC_POSITION
158	bool "SOF force to use IPC for position update on SKL+"
159	help
160	  This option forces to handle stream position update IPCs and run PCM
161	  elapse to inform ALSA about that, on platforms (e.g. Intel SKL+) that
162	  with other approach (e.g. HDAC DPIB/posbuf) to elapse PCM.
163	  On platforms (e.g. Intel SKL-) where position update IPC is the only
164	  one choice, this setting won't impact anything.
165	  If you are trying to debug pointer update with position IPCs or where
166	  DPIB/posbuf is not ready, select "Y".
167	  If unsure select "N".
168
169config SND_SOC_SOF_DEBUG_ENABLE_DEBUGFS_CACHE
170	bool "SOF enable debugfs caching"
171	help
172	  This option enables caching of debugfs
173	  memory -> DSP resource (memory, register, etc)
174	  before the audio DSP is suspended. This will increase the suspend
175	  latency and therefore should be used for debug purposes only.
176	  Say Y if you want to enable caching the memory windows.
177	  If unsure, select "N".
178
179config SND_SOC_SOF_DEBUG_ENABLE_FIRMWARE_TRACE
180	bool "SOF enable firmware trace"
181	help
182	  The firmware trace can be enabled either at build-time with
183	  this option, or dynamically by setting flags in the SOF core
184	  module parameter (similar to dynamic debug).
185	  If unsure, select "N".
186
187config SND_SOC_SOF_DEBUG_IPC_FLOOD_TEST
188	bool "SOF enable IPC flood test"
189	help
190	  This option enables the IPC flood test which can be used to flood
191	  the DSP with test IPCs and gather stats about response times.
192	  Say Y if you want to enable IPC flood test.
193	  If unsure, select "N".
194
195config SND_SOC_SOF_DEBUG_RETAIN_DSP_CONTEXT
196	bool "SOF retain DSP context on any FW exceptions"
197	help
198	  This option keeps the DSP in D0 state so that firmware debug
199	  information can be retained and dumped to userspace.
200	  Say Y if you want to retain DSP context for FW exceptions.
201	  If unsure, select "N".

223	  When selected, the probe is handled in two steps, for example to
224	  avoid lockdeps if request_module is used in the probe.
