2 config SND_SOC_SOF_TOPLEVEL
3 bool "Sound Open Firmware Support"
5 This adds support for Sound Open Firmware (SOF). SOF is a 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.

17 select SND_SOC_SOF_OPTIONS
18 select SND_SOC_SOF_INTEL_PCI if SND_SOC_SOF_INTEL_TOPLEVEL
20 This adds support for PCI enumeration. This option is
21 required to enable Intel Skylake+ devices
22 Say Y if you need this option

34 This adds support for ACPI enumeration. This option is required
35 to enable Intel Haswell/Broadwell/Baytrail/Cherrytrail devices
36 Say Y if you need this option
40 tristate "SOF OF enumeration support"
41 depends on OF || COMPILE_TEST
43 select SND_SOC_SOF_OPTIONS
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_OPTIONS
52 This option is not user-selectable but automagically handled by
53 'select' statements at a higher level
55 if SND_SOC_SOF_OPTIONS
57 config SND_SOC_SOF_NOCODEC
60 config SND_SOC_SOF_NOCODEC_SUPPORT
61 bool "SOF nocodec mode support"
63 This adds support for a dummy/nocodec machine driver fallback
64 option if no known codec is detected. This is typically only
65 enabled for developers or devices where the sound card is
67 Say Y if you need this nocodec fallback option
70 config SND_SOC_SOF_STRICT_ABI_CHECKS
71 bool "SOF strict ABI checks"
73 This option enables strict ABI checks for firmware and topology
75 When these files are more recent than the kernel, the kernel
76 will handle the functionality it supports and may report errors
77 during topology creation or run-time usage if new functionality
79 This option will stop topology creation and firmware load upfront.
80 It is intended for SOF CI/releases and not for users or distros.
81 Say Y if you want strict ABI checks for an SOF release
82 If you are not involved in SOF releases and CI development
85 config SND_SOC_SOF_DEBUG
86 bool "SOF debugging features"
88 This option can be used to enable or disable individual SOF firmware
89 and driver debugging options.
90 Say Y if you are debugging SOF FW or drivers.
95 config SND_SOC_SOF_FORCE_NOCODEC_MODE
96 bool "SOF force nocodec Mode"
97 depends on SND_SOC_SOF_NOCODEC_SUPPORT
99 This forces SOF to use dummy/nocodec as machine driver, even
100 though there is a codec detected on the real platform. This is
101 typically only enabled for developers for debug purposes, before
102 codec/machine driver is ready, or to exclude the impact of those
104 Say Y if you need this force nocodec mode option
105 If unsure select "N".
107 config SND_SOC_SOF_DEBUG_XRUN_STOP
108 bool "SOF stop on XRUN"
110 This option forces PCMs to stop on any XRUN event. This is useful to
111 preserve any trace data ond pipeline status prior to the XRUN.
112 Say Y if you are debugging SOF FW pipeline XRUNs.
113 If unsure select "N".
115 config SND_SOC_SOF_DEBUG_VERBOSE_IPC
116 bool "SOF verbose IPC logs"
118 This option enables more verbose IPC logs, with command types in
119 human-readable form instead of just 32-bit hex dumps. This is useful
120 if you are trying to debug IPC with the DSP firmware.
121 If unsure select "N".
123 config SND_SOC_SOF_DEBUG_FORCE_IPC_POSITION
124 bool "SOF force to use IPC for position update on SKL+"
126 This option force to handle stream position update IPCs and run pcm
127 elapse to inform ALSA about that, on platforms (e.g. Intel SKL+) that
128 with other approach (e.g. HDAC DPIB/posbuf) to elapse PCM.
129 On platforms (e.g. Intel SKL-) where position update IPC is the only
130 one choice, this setting won't impact anything.
131 if you are trying to debug pointer update with position IPCs or where
132 DPIB/posbuf is not ready, select "Y".
133 If unsure select "N".
135 config SND_SOC_SOF_DEBUG_ENABLE_DEBUGFS_CACHE
136 bool "SOF enable debugfs caching"
138 This option enables caching of debugfs
139 memory -> DSP resource (memory, register, etc)
140 before the audio DSP is suspended. This will increase the suspend
141 latency and therefore should be used for debug purposes only.
142 Say Y if you want to enable caching the memory windows.
143 If unsure, select "N".
145 config SND_SOC_SOF_DEBUG_IPC_FLOOD_TEST
146 bool "SOF enable IPC flood test"
148 This option enables the IPC flood test which can be used to flood
149 the DSP with test IPCs and gather stats about response times.
150 Say Y if you want to enable IPC flood test.
151 If unsure, select "N".

160 select SND_SOC_SOF_NOCODEC if SND_SOC_SOF_NOCODEC_SUPPORT
162 This option is not user-selectable but automagically handled by
163 'select' statements at a higher level
164 The selection is made at the top level and does not exactly follow
165 module dependencies but since the module or built-in type is decided
166 at the top level it doesn't matter.
168 config SND_SOC_SOF_PROBE_WORK_QUEUE
171 This option is not user-selectable but automagically handled by
172 'select' statements at a higher level
173 When selected, the probe is handled in two steps, for example to
174 avoid lockdeps if request_module is used in the probe.
