2 config SND_SOC_SOF_TOPLEVEL
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"
42 depends on OF || COMPILE_TEST
45 This adds support for Device Tree enumeration. This option is
46 required to enable i.MX8 devices.
47 Say Y if you need this option. If unsure select "N".
49 config SND_SOC_SOF_DEBUG_PROBES
50 bool "SOF enable data probing"
51 select SND_SOC_COMPRESS
53 This option enables the data probing feature that can be used to
54 gather data directly from specific points of the audio pipeline.
55 Say Y if you want to enable probes.
56 If unsure, select "N".
58 config SND_SOC_SOF_DEVELOPER_SUPPORT
59 bool "SOF developer options support"
62 This option unlocks SOF developer options for debug/performance/
64 Distributions should not select this option, only SOF development
65 teams should select it.
66 Say Y if you are involved in SOF development and need this option.
69 if SND_SOC_SOF_DEVELOPER_SUPPORT
71 config SND_SOC_SOF_FORCE_PROBE_WORKQUEUE
72 bool "SOF force probe workqueue"
73 select SND_SOC_SOF_PROBE_WORK_QUEUE
75 This option forces the use of a probe workqueue, which is only used
76 when HDaudio is enabled due to module dependencies. Forcing this
77 option is intended for debug only, but this should not add any
78 functional issues in nominal cases.
79 Say Y if you are involved in SOF development and need this option.
82 config SND_SOC_SOF_NOCODEC
85 config SND_SOC_SOF_NOCODEC_SUPPORT
86 bool "SOF nocodec mode support"
88 This adds support for a dummy/nocodec machine driver fallback
89 option if no known codec is detected. This is typically only
90 enabled for developers or devices where the sound card is
91 controlled externally.
92 This option is mutually exclusive with the Intel HDAudio support.
93 Selecting it may have negative impacts and prevent e.g. microphone
94 functionality from being enabled on Intel CoffeeLake and later
96 Distributions should not select this option!
97 Say Y if you need this nocodec fallback option.
100 config SND_SOC_SOF_STRICT_ABI_CHECKS
101 bool "SOF strict ABI checks"
103 This option enables strict ABI checks for firmware and topology
105 When these files are more recent than the kernel, the kernel
106 will handle the functionality it supports and may report errors
107 during topology creation or run-time usage if new functionality
109 This option will stop topology creation and firmware load upfront.
110 It is intended for SOF CI/releases and not for users or distros.
111 Say Y if you want strict ABI checks for an SOF release.
112 If you are not involved in SOF releases and CI development,
115 config SND_SOC_SOF_DEBUG
116 bool "SOF debugging features"
118 This option can be used to enable or disable individual SOF firmware
119 and driver debugging options.
120 Say Y if you are debugging SOF FW or drivers.
121 If unsure select "N".
125 config SND_SOC_SOF_FORCE_NOCODEC_MODE
126 bool "SOF force nocodec Mode"
127 depends on SND_SOC_SOF_NOCODEC_SUPPORT
129 This forces SOF to use dummy/nocodec as machine driver, even
130 though there is a codec detected on the real platform. This is
131 typically only enabled for developers for debug purposes, before
132 codec/machine driver is ready, or to exclude the impact of those
134 Say Y if you need this force nocodec mode option.
135 If unsure select "N".
137 config SND_SOC_SOF_DEBUG_XRUN_STOP
138 bool "SOF stop on XRUN"
140 This option forces PCMs to stop on any XRUN event. This is useful to
141 preserve any trace data and pipeline status prior to the XRUN.
142 Say Y if you are debugging SOF FW pipeline XRUNs.
143 If unsure select "N".
145 config SND_SOC_SOF_DEBUG_VERBOSE_IPC
146 bool "SOF verbose IPC logs"
148 This option enables more verbose IPC logs, with command types in
149 human-readable form instead of just 32-bit hex dumps. This is useful
150 if you are trying to debug IPC with the DSP firmware.
151 If unsure select "N".
153 config SND_SOC_SOF_DEBUG_FORCE_IPC_POSITION
154 bool "SOF force to use IPC for position update on SKL+"
156 This option forces to handle stream position update IPCs and run PCM
157 elapse to inform ALSA about that, on platforms (e.g. Intel SKL+) that
158 with other approach (e.g. HDAC DPIB/posbuf) to elapse PCM.
159 On platforms (e.g. Intel SKL-) where position update IPC is the only
160 one choice, this setting won't impact anything.
161 If you are trying to debug pointer update with position IPCs or where
162 DPIB/posbuf is not ready, select "Y".
163 If unsure select "N".
165 config SND_SOC_SOF_DEBUG_ENABLE_DEBUGFS_CACHE
166 bool "SOF enable debugfs caching"
168 This option enables caching of debugfs
169 memory -> DSP resource (memory, register, etc)
170 before the audio DSP is suspended. This will increase the suspend
171 latency and therefore should be used for debug purposes only.
172 Say Y if you want to enable caching the memory windows.
173 If unsure, select "N".
175 config SND_SOC_SOF_DEBUG_ENABLE_FIRMWARE_TRACE
176 bool "SOF enable firmware trace"
178 The firmware trace can be enabled either at build-time with
179 this option, or dynamically by setting flags in the SOF core
180 module parameter (similar to dynamic debug).
181 If unsure, select "N".
183 config SND_SOC_SOF_DEBUG_IPC_FLOOD_TEST
184 bool "SOF enable IPC flood test"
186 This option enables the IPC flood test which can be used to flood
187 the DSP with test IPCs and gather stats about response times.
188 Say Y if you want to enable IPC flood test.
189 If unsure, select "N".
191 config SND_SOC_SOF_DEBUG_RETAIN_DSP_CONTEXT
192 bool "SOF retain DSP context on any FW exceptions"
194 This option keeps the DSP in D0 state so that firmware debug
195 information can be retained and dumped to userspace.
196 Say Y if you want to retain DSP context for FW exceptions.
197 If unsure, select "N".

205 select SND_SOC_TOPOLOGY
206 select SND_SOC_SOF_NOCODEC if SND_SOC_SOF_NOCODEC_SUPPORT
208 This option is not user-selectable but automagically handled by
209 'select' statements at a higher level.
210 The selection is made at the top level and does not exactly follow
211 module dependencies but since the module or built-in type is decided
212 at the top level it doesn't matter.
214 config SND_SOC_SOF_PROBE_WORK_QUEUE
217 This option is not user-selectable but automagically handled by
218 'select' statements at a higher level.
219 When selected, the probe is handled in two steps, for example to
220 avoid lockdeps if request_module is used in the probe.
