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.
10 if SND_SOC_SOF_TOPLEVEL

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
48 tristate "SOF nocodec mode Support"
50 This adds support for a dummy/nocodec machine driver fallback
51 option if no known codec is detected. This is typically only
52 enabled for developers or devices where the sound card is
54 Say Y if you need this nocodec fallback option
57 config SND_SOC_SOF_STRICT_ABI_CHECKS
58 bool "SOF strict ABI checks"
60 This option enables strict ABI checks for firmware and topology
62 When these files are more recent than the kernel, the kernel
63 will handle the functionality it supports and may report errors
64 during topology creation or run-time usage if new functionality
66 This option will stop topology creation and firmware load upfront.
67 It is intended for SOF CI/releases and not for users or distros.
68 Say Y if you want strict ABI checks for an SOF release
69 If you are not involved in SOF releases and CI development
72 config SND_SOC_SOF_DEBUG
73 bool "SOF debugging features"
75 This option can be used to enable or disable individual SOF firmware
76 and driver debugging options.
77 Say Y if you are debugging SOF FW or drivers.
82 config SND_SOC_SOF_FORCE_NOCODEC_MODE
83 bool "SOF force nocodec Mode"
84 depends on SND_SOC_SOF_NOCODEC
86 This forces SOF to use dummy/nocodec as machine driver, even
87 though there is a codec detected on the real platform. This is
88 typically only enabled for developers for debug purposes, before
89 codec/machine driver is ready, or to exclude the impact of those
91 Say Y if you need this force nocodec mode option
94 config SND_SOC_SOF_DEBUG_XRUN_STOP
95 bool "SOF stop on XRUN"
97 This option forces PCMs to stop on any XRUN event. This is useful to
98 preserve any trace data ond pipeline status prior to the XRUN.
99 Say Y if you are debugging SOF FW pipeline XRUNs.
100 If unsure select "N".
102 config SND_SOC_SOF_DEBUG_VERBOSE_IPC
103 bool "SOF verbose IPC logs"
105 This option enables more verbose IPC logs, with command types in
106 human-readable form instead of just 32-bit hex dumps. This is useful
107 if you are trying to debug IPC with the DSP firmware.
108 If unsure select "N".
110 config SND_SOC_SOF_DEBUG_FORCE_IPC_POSITION
111 bool "SOF force to use IPC for position update on SKL+"
113 This option force to handle stream position update IPCs and run pcm
114 elapse to inform ALSA about that, on platforms (e.g. Intel SKL+) that
115 with other approach (e.g. HDAC DPIB/posbuf) to elapse PCM.
116 On platforms (e.g. Intel SKL-) where position update IPC is the only
117 one choice, this setting won't impact anything.
118 if you are trying to debug pointer update with position IPCs or where
119 DPIB/posbuf is not ready, select "Y".
120 If unsure select "N".
122 config SND_SOC_SOF_DEBUG_ENABLE_DEBUGFS_CACHE
123 bool "SOF enable debugfs caching"
125 This option enables caching of debugfs
126 memory -> DSP resource (memory, register, etc)
127 before the audio DSP is suspended. This will increase the suspend
128 latency and therefore should be used for debug purposes only.
129 Say Y if you want to enable caching the memory windows.
130 If unsure, select "N".

138 select SND_SOC_TOPOLOGY
140 This option is not user-selectable but automagically handled by
141 'select' statements at a higher level
142 The selection is made at the top level and does not exactly follow
143 module dependencies but since the module or built-in type is decided
144 at the top level it doesn't matter.
146 config SND_SOC_SOF_PROBE_WORK_QUEUE
149 This option is not user-selectable but automagically handled by
150 'select' statements at a higher level
151 When selected, the probe is handled in two steps, for example to
152 avoid lockdeps if request_module is used in the probe.
