6 generic open source audio DSP firmware for multiple devices.

61 bool "SOF nocodec mode support"
62 help
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
66 controlled externally
67 This option is mutually exclusive with the Intel HDaudio support,
68 selecting it may have negative impacts and prevent e.g. microphone
69 functionality from being enabled on Intel CoffeeLake and later
70 platforms.
71 Distributions should not select this option!

73 If unsure select "N".

76 bool "SOF strict ABI checks"
77 help
78 This option enables strict ABI checks for firmware and topology
79 files.
80 When these files are more recent than the kernel, the kernel
81 will handle the functionality it supports and may report errors
82 during topology creation or run-time usage if new functionality
83 is invoked.
84 This option will stop topology creation and firmware load upfront.
85 It is intended for SOF CI/releases and not for users or distros.
86 Say Y if you want strict ABI checks for an SOF release
87 If you are not involved in SOF releases and CI development
88 select "N".

103 help
104 This forces SOF to use dummy/nocodec as machine driver, even
105 though there is a codec detected on the real platform. This is
106 typically only enabled for developers for debug purposes, before
107 codec/machine driver is ready, or to exclude the impact of those
108 drivers

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

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

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

141 bool "SOF enable debugfs caching"
142 help
143 This option enables caching of debugfs
144 memory -> DSP resource (memory, register, etc)
145 before the audio DSP is suspended. This will increase the suspend
146 latency and therefore should be used for debug purposes only.
147 Say Y if you want to enable caching the memory windows.

155 module parameter (similar to dynamic debug)
