This is typically only 96 enabled for developers or devices where the sound card is 97 controlled externally. 98 This option is mutually exclusive with the Intel HDAudio support. 99 Selecting it may have negative impacts and prevent e.g. microphone 100 functionality from being enabled on Intel CoffeeLake and later 101 platforms. 102 Distributions should not select this option! 103 Say Y if you need this nocodec fallback option. 104 If unsure select "N". 105 106config SND_SOC_SOF_STRICT_ABI_CHECKS 107 bool "SOF strict ABI checks" 108 help 109 This option enables strict ABI checks for firmware and topology 110 files. 111 When these files are more recent than the kernel, the kernel 112 will handle the functionality it supports and may report errors 113 during topology creation or run-time usage if new functionality 114 is invoked. 115 This option will stop topology creation and firmware load upfront. 116 It is intended for SOF CI/releases and not for users or distros. 117 Say Y if you want strict ABI checks for an SOF release. 118 If you are not involved in SOF releases and CI development, 119 select "N". 120 121config SND_SOC_SOF_DEBUG 122 bool "SOF debugging features" 123 help 124 This option can be used to enable or disable individual SOF firmware 125 and driver debugging options. 126 Say Y if you are debugging SOF FW or drivers. 127 If unsure select "N". 128 129if SND_SOC_SOF_DEBUG 130 131config SND_SOC_SOF_FORCE_NOCODEC_MODE 132 bool "SOF force nocodec Mode" 133 depends on SND_SOC_SOF_NOCODEC_SUPPORT 134 help 135 This forces SOF to use dummy/nocodec as machine driver, even 136 though there is a codec detected on the real platform. This is 137 typically only enabled for developers for debug purposes, before 138 codec/machine driver is ready, or to exclude the impact of those 139 drivers. 140 Say Y if you need this force nocodec mode option. 141 If unsure select "N". 142 143config SND_SOC_SOF_DEBUG_XRUN_STOP 144 bool "SOF stop on XRUN" 145 help 146 This option forces PCMs to stop on any XRUN event.

This will increase the suspend 177 latency and therefore should be used for debug purposes only. 178 Say Y if you want to enable caching the memory windows. 179 If unsure, select "N". 180 181config SND_SOC_SOF_DEBUG_ENABLE_FIRMWARE_TRACE 182 bool "SOF enable firmware trace" 183 help 184 The firmware trace can be enabled either at build-time with 185 this option, or dynamically by setting flags in the SOF core 186 module parameter (similar to dynamic debug). 187 If unsure, select "N". 188 189config SND_SOC_SOF_DEBUG_IPC_FLOOD_TEST 190 bool "SOF enable IPC flood test" 191 help 192 This option enables the IPC flood test which can be used to flood 193 the DSP with test IPCs and gather stats about response times. 194 Say Y if you want to enable IPC flood test. 195 If unsure, select "N". 196 197config SND_SOC_SOF_DEBUG_IPC_MSG_INJECTOR 198 bool "SOF enable IPC message injector" 199 help 200 This option enables the IPC message injector which can be used to send 201 crafted IPC messages to the DSP to test its robustness. 202 Say Y if you want to enable the IPC message injector. 203 If unsure, select "N". 204 205config SND_SOC_SOF_DEBUG_RETAIN_DSP_CONTEXT 206 bool "SOF retain DSP context on any FW exceptions" 207 help 208 This option keeps the DSP in D0 state so that firmware debug 209 information can be retained and dumped to userspace. 210 Say Y if you want to retain DSP context for FW exceptions. 211 If unsure, select "N". 212 213endif ## SND_SOC_SOF_DEBUG 214 215endif ## SND_SOC_SOF_DEVELOPER_SUPPORT 216 217config SND_SOC_SOF 218 tristate 219 select SND_SOC_TOPOLOGY 220 select SND_SOC_SOF_NOCODEC if SND_SOC_SOF_NOCODEC_SUPPORT 221 help 222 This option is not user-selectable but automagically handled by 223 'select' statements at a higher level. 224 The selection is made at the top level and does not exactly follow 225 module dependencies but since the module or built-in type is decided 226 at the top level it doesn't matter. 227 228config SND_SOC_SOF_PROBE_WORK_QUEUE 229 bool 230 help 231 This option is not user-selectable but automagically handled by 232 'select' statements at a higher level. 233 When selected, the probe is handled in two steps, for example to 234 avoid lockdeps if request_module is used in the probe. 235 236source "sound/soc/sof/imx/Kconfig" 237source "sound/soc/sof/intel/Kconfig" 238source "sound/soc/sof/xtensa/Kconfig" 239 240endif 241
