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.

16 select SND_SOC_ACPI if ACPI
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
25 config SND_SOC_SOF_ACPI
26 tristate "SOF ACPI enumeration support"
27 depends on ACPI || COMPILE_TEST

30 select SND_SOC_SOF_OPTIONS
31 select SND_SOC_SOF_INTEL_ACPI if SND_SOC_SOF_INTEL_TOPLEVEL
32 select IOSF_MBI if X86 && PCI
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
39 config SND_SOC_SOF_OPTIONS
42 This option is not user-selectable but automagically handled by
43 'select' statements at a higher level
45 if SND_SOC_SOF_OPTIONS
47 config SND_SOC_SOF_NOCODEC
50 config SND_SOC_SOF_NOCODEC_SUPPORT
51 bool "SOF nocodec mode support"
53 This adds support for a dummy/nocodec machine driver fallback
54 option if no known codec is detected. This is typically only
55 enabled for developers or devices where the sound card is
57 Say Y if you need this nocodec fallback option
60 config SND_SOC_SOF_STRICT_ABI_CHECKS
61 bool "SOF strict ABI checks"
63 This option enables strict ABI checks for firmware and topology
65 When these files are more recent than the kernel, the kernel
66 will handle the functionality it supports and may report errors
67 during topology creation or run-time usage if new functionality
69 This option will stop topology creation and firmware load upfront.
70 It is intended for SOF CI/releases and not for users or distros.
71 Say Y if you want strict ABI checks for an SOF release
72 If you are not involved in SOF releases and CI development
75 config SND_SOC_SOF_DEBUG
76 bool "SOF debugging features"
78 This option can be used to enable or disable individual SOF firmware
79 and driver debugging options.
80 Say Y if you are debugging SOF FW or drivers.
85 config SND_SOC_SOF_FORCE_NOCODEC_MODE
86 bool "SOF force nocodec Mode"
87 depends on SND_SOC_SOF_NOCODEC_SUPPORT
89 This forces SOF to use dummy/nocodec as machine driver, even
90 though there is a codec detected on the real platform. This is
91 typically only enabled for developers for debug purposes, before
92 codec/machine driver is ready, or to exclude the impact of those
94 Say Y if you need this force nocodec mode option
97 config SND_SOC_SOF_DEBUG_XRUN_STOP
98 bool "SOF stop on XRUN"
100 This option forces PCMs to stop on any XRUN event. This is useful to
101 preserve any trace data ond pipeline status prior to the XRUN.
102 Say Y if you are debugging SOF FW pipeline XRUNs.
103 If unsure select "N".
105 config SND_SOC_SOF_DEBUG_VERBOSE_IPC
106 bool "SOF verbose IPC logs"
108 This option enables more verbose IPC logs, with command types in
109 human-readable form instead of just 32-bit hex dumps. This is useful
110 if you are trying to debug IPC with the DSP firmware.
111 If unsure select "N".
113 config SND_SOC_SOF_DEBUG_FORCE_IPC_POSITION
114 bool "SOF force to use IPC for position update on SKL+"
116 This option force to handle stream position update IPCs and run pcm
117 elapse to inform ALSA about that, on platforms (e.g. Intel SKL+) that
118 with other approach (e.g. HDAC DPIB/posbuf) to elapse PCM.
119 On platforms (e.g. Intel SKL-) where position update IPC is the only
120 one choice, this setting won't impact anything.
121 if you are trying to debug pointer update with position IPCs or where
122 DPIB/posbuf is not ready, select "Y".
123 If unsure select "N".
125 config SND_SOC_SOF_DEBUG_ENABLE_DEBUGFS_CACHE
126 bool "SOF enable debugfs caching"
128 This option enables caching of debugfs
129 memory -> DSP resource (memory, register, etc)
130 before the audio DSP is suspended. This will increase the suspend
131 latency and therefore should be used for debug purposes only.
132 Say Y if you want to enable caching the memory windows.
133 If unsure, select "N".
135 config SND_SOC_SOF_DEBUG_IPC_FLOOD_TEST
136 bool "SOF enable IPC flood test"
138 This option enables the IPC flood test which can be used to flood
139 the DSP with test IPCs and gather stats about response times.
140 Say Y if you want to enable IPC flood test.
141 If unsure, select "N".

149 select SND_SOC_TOPOLOGY
150 select SND_SOC_SOF_NOCODEC if SND_SOC_SOF_NOCODEC_SUPPORT
152 This option is not user-selectable but automagically handled by
153 'select' statements at a higher level
154 The selection is made at the top level and does not exactly follow
155 module dependencies but since the module or built-in type is decided
156 at the top level it doesn't matter.
158 config SND_SOC_SOF_PROBE_WORK_QUEUE
161 This option is not user-selectable but automagically handled by
162 'select' statements at a higher level
163 When selected, the probe is handled in two steps, for example to
164 avoid lockdeps if request_module is used in the probe.
