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

This will increase the suspend 184 latency and therefore should be used for debug purposes only. 185 Say Y if you want to enable caching the memory windows. 186 If unsure, select "N". 187 188config SND_SOC_SOF_DEBUG_ENABLE_FIRMWARE_TRACE 189 bool "SOF enable firmware trace" 190 help 191 The firmware trace can be enabled either at build-time with 192 this option, or dynamically by setting flags in the SOF core 193 module parameter (similar to dynamic debug). 194 If unsure, select "N". 195 196config SND_SOC_SOF_DEBUG_IPC_FLOOD_TEST 197 bool "SOF enable IPC flood test" 198 help 199 This option enables the IPC flood test which can be used to flood 200 the DSP with test IPCs and gather stats about response times. 201 Say Y if you want to enable IPC flood test. 202 If unsure, select "N". 203 204config SND_SOC_SOF_DEBUG_IPC_MSG_INJECTOR 205 bool "SOF enable IPC message injector" 206 help 207 This option enables the IPC message injector which can be used to send 208 crafted IPC messages to the DSP to test its robustness. 209 Say Y if you want to enable the IPC message injector. 210 If unsure, select "N". 211 212config SND_SOC_SOF_DEBUG_RETAIN_DSP_CONTEXT 213 bool "SOF retain DSP context on any FW exceptions" 214 help 215 This option keeps the DSP in D0 state so that firmware debug 216 information can be retained and dumped to userspace. 217 Say Y if you want to retain DSP context for FW exceptions. 218 If unsure, select "N". 219 220endif ## SND_SOC_SOF_DEBUG 221 222endif ## SND_SOC_SOF_DEVELOPER_SUPPORT 223 224config SND_SOC_SOF 225 tristate 226 select SND_SOC_TOPOLOGY 227 select SND_SOC_SOF_NOCODEC if SND_SOC_SOF_NOCODEC_SUPPORT 228 help 229 This option is not user-selectable but automagically handled by 230 'select' statements at a higher level. 231 The selection is made at the top level and does not exactly follow 232 module dependencies but since the module or built-in type is decided 233 at the top level it doesn't matter. 234 235config SND_SOC_SOF_PROBE_WORK_QUEUE 236 bool 237 help 238 This option is not user-selectable but automagically handled by 239 'select' statements at a higher level. 240 When selected, the probe is handled in two steps, for example to 241 avoid lockdeps if request_module is used in the probe. 242 243source "sound/soc/sof/amd/Kconfig" 244source "sound/soc/sof/imx/Kconfig" 245source "sound/soc/sof/intel/Kconfig" 246source "sound/soc/sof/mediatek/Kconfig" 247source "sound/soc/sof/xtensa/Kconfig" 248 249endif 250
