This is typically only 76 enabled for developers or devices where the sound card is 77 controlled externally. 78 This option is mutually exclusive with the Intel HDAudio support. 79 Selecting it may have negative impacts and prevent e.g. microphone 80 functionality from being enabled on Intel CoffeeLake and later 81 platforms. 82 Distributions should not select this option! 83 Say Y if you need this nocodec fallback option. 84 If unsure select "N". 85 86config SND_SOC_SOF_STRICT_ABI_CHECKS 87 bool "SOF strict ABI checks" 88 help 89 This option enables strict ABI checks for firmware and topology 90 files. 91 When these files are more recent than the kernel, the kernel 92 will handle the functionality it supports and may report errors 93 during topology creation or run-time usage if new functionality 94 is invoked. 95 This option will stop topology creation and firmware load upfront. 96 It is intended for SOF CI/releases and not for users or distros. 97 Say Y if you want strict ABI checks for an SOF release. 98 If you are not involved in SOF releases and CI development, 99 select "N". 100 101config SND_SOC_SOF_DEBUG 102 bool "SOF debugging features" 103 help 104 This option can be used to enable or disable individual SOF firmware 105 and driver debugging options. 106 Say Y if you are debugging SOF FW or drivers. 107 If unsure select "N". 108 109if SND_SOC_SOF_DEBUG 110 111config SND_SOC_SOF_FORCE_NOCODEC_MODE 112 bool "SOF force nocodec Mode" 113 depends on SND_SOC_SOF_NOCODEC_SUPPORT 114 help 115 This forces SOF to use dummy/nocodec as machine driver, even 116 though there is a codec detected on the real platform. This is 117 typically only enabled for developers for debug purposes, before 118 codec/machine driver is ready, or to exclude the impact of those 119 drivers. 120 Say Y if you need this force nocodec mode option. 121 If unsure select "N". 122 123config SND_SOC_SOF_DEBUG_XRUN_STOP 124 bool "SOF stop on XRUN" 125 help 126 This option forces PCMs to stop on any XRUN event.

This will increase the suspend 157 latency and therefore should be used for debug purposes only. 158 Say Y if you want to enable caching the memory windows. 159 If unsure, select "N". 160 161config SND_SOC_SOF_DEBUG_ENABLE_FIRMWARE_TRACE 162 bool "SOF enable firmware trace" 163 help 164 The firmware trace can be enabled either at build-time with 165 this option, or dynamically by setting flags in the SOF core 166 module parameter (similar to dynamic debug). 167 If unsure, select "N". 168 169config SND_SOC_SOF_DEBUG_IPC_FLOOD_TEST 170 bool "SOF enable IPC flood test" 171 help 172 This option enables the IPC flood test which can be used to flood 173 the DSP with test IPCs and gather stats about response times. 174 Say Y if you want to enable IPC flood test. 175 If unsure, select "N". 176 177config SND_SOC_SOF_DEBUG_RETAIN_DSP_CONTEXT 178 bool "SOF retain DSP context on any FW exceptions" 179 help 180 This option keeps the DSP in D0 state so that firmware debug 181 information can be retained and dumped to userspace. 182 Say Y if you want to retain DSP context for FW exceptions. 183 If unsure, select "N". 184 185endif ## SND_SOC_SOF_DEBUG 186 187endif ## SND_SOC_SOF_DEVELOPER_SUPPORT 188 189config SND_SOC_SOF 190 tristate 191 select SND_SOC_TOPOLOGY 192 select SND_SOC_SOF_NOCODEC if SND_SOC_SOF_NOCODEC_SUPPORT 193 help 194 This option is not user-selectable but automagically handled by 195 'select' statements at a higher level. 196 The selection is made at the top level and does not exactly follow 197 module dependencies but since the module or built-in type is decided 198 at the top level it doesn't matter. 199 200config SND_SOC_SOF_PROBE_WORK_QUEUE 201 bool 202 help 203 This option is not user-selectable but automagically handled by 204 'select' statements at a higher level. 205 When selected, the probe is handled in two steps, for example to 206 avoid lockdeps if request_module is used in the probe. 207 208source "sound/soc/sof/imx/Kconfig" 209source "sound/soc/sof/intel/Kconfig" 210source "sound/soc/sof/xtensa/Kconfig" 211 212endif 213
