3 bool "Sound Open Firmware Support"
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.
10 if SND_SOC_SOF_TOPLEVEL
12 config SND_SOC_SOF_PCI_DEV
15 config SND_SOC_SOF_PCI
16 tristate "SOF PCI enumeration support"
19 This adds support for PCI enumeration. This option is
20 required to enable Intel Skylake+ devices.
21 For backwards-compatibility with previous configurations the selection will
22 be used as default for platform-specific drivers.
23 Say Y if you need this option.
26 config SND_SOC_SOF_ACPI
27 tristate "SOF ACPI enumeration support"
28 depends on ACPI || COMPILE_TEST
30 This adds support for ACPI enumeration. This option is required
31 to enable Intel Broadwell/Baytrail/Cherrytrail devices.
32 For backwards-compatibility with previous configurations the selection will
33 be used as default for platform-specific drivers.
34 Say Y if you need this option.
37 config SND_SOC_SOF_ACPI_DEV
41 tristate "SOF OF enumeration support"
44 This adds support for Device Tree enumeration. This option is
45 required to enable i.MX8 or Mediatek devices.
46 Say Y if you need this option. If unsure select "N".

53 select SND_SOC_COMPRESS
55 config SND_SOC_SOF_DEBUG_PROBES
57 select SND_SOC_SOF_CLIENT
58 select SND_SOC_COMPRESS
60 This option enables the data probing feature that can be used to
61 gather data directly from specific points of the audio pipeline.
62 This option is not user-selectable but automagically handled by
63 'select' statements at a higher level.
65 config SND_SOC_SOF_CLIENT
69 This option is not user-selectable but automagically handled by
70 'select' statements at a higher level.
72 config SND_SOC_SOF_DEVELOPER_SUPPORT
73 bool "SOF developer options support"
74 depends on EXPERT && SND_SOC_SOF
76 This option unlocks SOF developer options for debug/performance/
78 Distributions should not select this option, only SOF development
79 teams should select it.
80 Say Y if you are involved in SOF development and need this option.
83 if SND_SOC_SOF_DEVELOPER_SUPPORT
85 config SND_SOC_SOF_FORCE_PROBE_WORKQUEUE
86 bool "SOF force probe workqueue"
87 select SND_SOC_SOF_PROBE_WORK_QUEUE
89 This option forces the use of a probe workqueue, which is only used
90 when HDaudio is enabled due to module dependencies. Forcing this
91 option is intended for debug only, but this should not add any
92 functional issues in nominal cases.
93 Say Y if you are involved in SOF development and need this option.
96 config SND_SOC_SOF_NOCODEC
99 config SND_SOC_SOF_NOCODEC_SUPPORT
100 bool "SOF nocodec static mode support"
102 This adds support for a dummy/nocodec machine driver fallback
103 option if no known codec is detected. This is typically only
104 enabled for developers or devices where the sound card is
105 controlled externally.
106 This option is mutually exclusive at build time with the Intel HDAudio support.
107 Selecting it may have negative impacts and prevent e.g. microphone
108 functionality from being enabled on Intel CoffeeLake and later
110 Distributions should not select this option!
111 Say Y if you need this nocodec fallback option.
112 If unsure select "N".
114 config SND_SOC_SOF_STRICT_ABI_CHECKS
115 bool "SOF strict ABI checks"
117 This option enables strict ABI checks for firmware and topology
119 When these files are more recent than the kernel, the kernel
120 will handle the functionality it supports and may report errors
121 during topology creation or run-time usage if new functionality
123 This option will stop topology creation and firmware load upfront.
124 It is intended for SOF CI/releases and not for users or distros.
125 Say Y if you want strict ABI checks for an SOF release.
126 If you are not involved in SOF releases and CI development,
129 config SND_SOC_SOF_ALLOW_FALLBACK_TO_NEWER_IPC_VERSION
130 bool "SOF allow fallback to newer IPC version"
132 This option will allow the kernel to try to 'fallback' to a newer IPC
133 version if there are missing firmware files to satisfy the default IPC
135 IPC version fallback to older versions is not affected by this option,
136 it is always available.
137 Say Y if you are involved in SOF development and need this option.
140 config SND_SOC_SOF_DEBUG
141 bool "SOF debugging features"
143 This option can be used to enable or disable individual SOF firmware
144 and driver debugging options.
145 Say Y if you are debugging SOF FW or drivers.
146 If unsure select "N".
150 config SND_SOC_SOF_NOCODEC_DEBUG_SUPPORT
151 bool "SOF nocodec debug mode support"
152 depends on !SND_SOC_SOF_NOCODEC_SUPPORT
154 This adds support for a dummy/nocodec machine driver fallback
156 Unlike the SND_SOC_SOF_NOCODEC_SUPPORT, this option is NOT
157 mutually exclusive at build with the Intel HDAudio support. The
158 selection will be done depending on command line or modprobe.d settings
159 Distributions should not select this option!
160 Say Y if you need this nocodec debug fallback option.
161 If unsure select "N".
163 config SND_SOC_SOF_FORCE_NOCODEC_MODE
164 bool "SOF force nocodec Mode"
165 depends on SND_SOC_SOF_NOCODEC_SUPPORT
167 This forces SOF to use dummy/nocodec as machine driver, even
168 though there is a codec detected on the real platform. This is
169 typically only enabled for developers for debug purposes, before
170 codec/machine driver is ready, or to exclude the impact of those
172 Say Y if you need this force nocodec mode option.
173 If unsure select "N".
175 config SND_SOC_SOF_DEBUG_XRUN_STOP
176 bool "SOF stop on XRUN"
178 This option forces PCMs to stop on any XRUN event. This is useful to
179 preserve any trace data and pipeline status prior to the XRUN.
180 Say Y if you are debugging SOF FW pipeline XRUNs.
181 If unsure select "N".
183 config SND_SOC_SOF_DEBUG_VERBOSE_IPC
184 bool "SOF verbose IPC logs"
186 This option enables more verbose IPC logs, with command types in
187 human-readable form instead of just 32-bit hex dumps. This is useful
188 if you are trying to debug IPC with the DSP firmware.
189 If unsure select "N".
191 config SND_SOC_SOF_DEBUG_FORCE_IPC_POSITION
192 bool "SOF force to use IPC for position update on SKL+"
194 This option forces to handle stream position update IPCs and run PCM
195 elapse to inform ALSA about that, on platforms (e.g. Intel SKL+) that
196 with other approach (e.g. HDAC DPIB/posbuf) to elapse PCM.
197 On platforms (e.g. Intel SKL-) where position update IPC is the only
198 one choice, this setting won't impact anything.
199 If you are trying to debug pointer update with position IPCs or where
200 DPIB/posbuf is not ready, select "Y".
201 If unsure select "N".
203 config SND_SOC_SOF_DEBUG_ENABLE_DEBUGFS_CACHE
204 bool "SOF enable debugfs caching"
206 This option enables caching of debugfs
207 memory -> DSP resource (memory, register, etc)
208 before the audio DSP is suspended. This will increase the suspend
209 latency and therefore should be used for debug purposes only.
210 Say Y if you want to enable caching the memory windows.
211 If unsure, select "N".
213 config SND_SOC_SOF_DEBUG_ENABLE_FIRMWARE_TRACE
214 bool "SOF enable firmware trace"
216 The firmware trace can be enabled either at build-time with
217 this option, or dynamically by setting flags in the SOF core
218 module parameter (similar to dynamic debug).
219 If unsure, select "N".
221 config SND_SOC_SOF_DEBUG_IPC_FLOOD_TEST
222 tristate "SOF enable IPC flood test"
223 depends on SND_SOC_SOF
224 select SND_SOC_SOF_CLIENT
226 This option enables a separate client device for IPC flood test
227 which can be used to flood the DSP with test IPCs and gather stats
228 about response times.
229 Say Y if you want to enable IPC flood test.
230 If unsure, select "N".
232 config SND_SOC_SOF_DEBUG_IPC_FLOOD_TEST_NUM

241 tristate "SOF enable IPC message injector"
242 depends on SND_SOC_SOF
243 select SND_SOC_SOF_CLIENT
245 This option enables the IPC message injector which can be used to send
246 crafted IPC messages to the DSP to test its robustness.
247 Say Y if you want to enable the IPC message injector.
248 If unsure, select "N".
250 config SND_SOC_SOF_DEBUG_IPC_KERNEL_INJECTOR
251 tristate "SOF enable IPC kernel injector"
252 depends on SND_SOC_SOF
253 select SND_SOC_SOF_CLIENT
255 This option enables the IPC kernel injector which can be used to send
256 crafted IPC messages to the kernel to test its robustness against
258 Say Y if you want to enable the IPC kernel injector.
259 If unsure, select "N".
261 config SND_SOC_SOF_DEBUG_RETAIN_DSP_CONTEXT
262 bool "SOF retain DSP context on any FW exceptions"
264 This option keeps the DSP in D0 state so that firmware debug
265 information can be retained and dumped to userspace.
266 Say Y if you want to retain DSP context for FW exceptions.
267 If unsure, select "N".

279 This option is not user-selectable but automagically handled by
280 'select' statements at a higher level.
281 The selection is made at the top level and does not exactly follow
282 module dependencies but since the module or built-in type is decided
283 at the top level it doesn't matter.
285 config SND_SOC_SOF_PROBE_WORK_QUEUE
288 This option is not user-selectable but automagically handled by
289 'select' statements at a higher level.
290 When selected, the probe is handled in two steps, for example to
291 avoid lockdeps if request_module is used in the probe.
