5 This adds support for Sound Open Firmware (SOF). SOF is a free and
6 generic open source audio DSP firmware for multiple devices.

71 help
72 This adds support for a dummy/nocodec machine driver fallback
73 option if no known codec is detected. This is typically only
74 enabled for developers or devices where the sound card is
75 controlled externally
76 This option is mutually exclusive with the Intel HDaudio support,
77 selecting it may have negative impacts and prevent e.g. microphone
78 functionality from being enabled on Intel CoffeeLake and later
79 platforms.
80 Distributions should not select this option!

82 If unsure select "N".

84config SND_SOC_SOF_STRICT_ABI_CHECKS
85 bool "SOF strict ABI checks"
86 help
87 This option enables strict ABI checks for firmware and topology
88 files.
89 When these files are more recent than the kernel, the kernel
90 will handle the functionality it supports and may report errors
91 during topology creation or run-time usage if new functionality
92 is invoked.
93 This option will stop topology creation and firmware load upfront.
94 It is intended for SOF CI/releases and not for users or distros.

96 If you are not involved in SOF releases and CI development
97 select "N".

112 help
113 This forces SOF to use dummy/nocodec as machine driver, even
114 though there is a codec detected on the real platform. This is
115 typically only enabled for developers for debug purposes, before
116 codec/machine driver is ready, or to exclude the impact of those
117 drivers

119 If unsure select "N".

124 This option forces PCMs to stop on any XRUN event. This is useful to
125 preserve any trace data ond pipeline status prior to the XRUN.

132 This option enables more verbose IPC logs, with command types in
133 human-readable form instead of just 32-bit hex dumps. This is useful
134 if you are trying to debug IPC with the DSP firmware.
135 If unsure select "N".

140 This option force to handle stream position update IPCs and run pcm
141 elapse to inform ALSA about that, on platforms (e.g. Intel SKL+) that
142 with other approach (e.g. HDAC DPIB/posbuf) to elapse PCM.
143 On platforms (e.g. Intel SKL-) where position update IPC is the only
144 one choice, this setting won't impact anything.
145 if you are trying to debug pointer update with position IPCs or where
146 DPIB/posbuf is not ready, select "Y".
147 If unsure select "N".

150 bool "SOF enable debugfs caching"
151 help
152 This option enables caching of debugfs
153 memory -> DSP resource (memory, register, etc)
154 before the audio DSP is suspended. This will increase the suspend
155 latency and therefore should be used for debug purposes only.
156 Say Y if you want to enable caching the memory windows.
157 If unsure, select "N".

164 module parameter (similar to dynamic debug)
