Forcing this 91 option is intended for debug only, but this should not add any 92 functional issues in nominal cases. 93 Say Y if you are involved in SOF development and need this option. 94 If not, select N. 95 96config SND_SOC_SOF_NOCODEC 97 tristate 98 99config SND_SOC_SOF_NOCODEC_SUPPORT 100 bool "SOF nocodec mode support" 101 help 102 This adds support for a dummy/nocodec machine driver fallback 103 option if no known codec is detected. This is typically only 104 enabled for developers or devices where the sound card is 105 controlled externally. 106 This option is mutually exclusive with the Intel HDAudio support. 107 Selecting it may have negative impacts and prevent e.g. microphone 108 functionality from being enabled on Intel CoffeeLake and later 109 platforms. 110 Distributions should not select this option! 111 Say Y if you need this nocodec fallback option. 112 If unsure select "N". 113 114config SND_SOC_SOF_STRICT_ABI_CHECKS 115 bool "SOF strict ABI checks" 116 help 117 This option enables strict ABI checks for firmware and topology 118 files. 119 When these files are more recent than the kernel, the kernel 120 will handle the functionality it supports and may report errors 121 during topology creation or run-time usage if new functionality 122 is invoked. 123 This option will stop topology creation and firmware load upfront. 124 It is intended for SOF CI/releases and not for users or distros. 125 Say Y if you want strict ABI checks for an SOF release. 126 If you are not involved in SOF releases and CI development, 127 select "N". 128 129config SND_SOC_SOF_DEBUG 130 bool "SOF debugging features" 131 help 132 This option can be used to enable or disable individual SOF firmware 133 and driver debugging options. 134 Say Y if you are debugging SOF FW or drivers. 135 If unsure select "N". 136 137if SND_SOC_SOF_DEBUG 138 139config SND_SOC_SOF_FORCE_NOCODEC_MODE 140 bool "SOF force nocodec Mode" 141 depends on SND_SOC_SOF_NOCODEC_SUPPORT 142 help 143 This forces SOF to use dummy/nocodec as machine driver, even 144 though there is a codec detected on the real platform. This is 145 typically only enabled for developers for debug purposes, before 146 codec/machine driver is ready, or to exclude the impact of those 147 drivers. 148 Say Y if you need this force nocodec mode option. 149 If unsure select "N". 150 151config SND_SOC_SOF_DEBUG_XRUN_STOP 152 bool "SOF stop on XRUN" 153 help 154 This option forces PCMs to stop on any XRUN event.

This will increase the suspend 185 latency and therefore should be used for debug purposes only. 186 Say Y if you want to enable caching the memory windows. 187 If unsure, select "N". 188 189config SND_SOC_SOF_DEBUG_ENABLE_FIRMWARE_TRACE 190 bool "SOF enable firmware trace" 191 help 192 The firmware trace can be enabled either at build-time with 193 this option, or dynamically by setting flags in the SOF core 194 module parameter (similar to dynamic debug). 195 If unsure, select "N". 196 197config SND_SOC_SOF_DEBUG_IPC_FLOOD_TEST 198 tristate "SOF enable IPC flood test" 199 select SND_SOC_SOF_CLIENT 200 help 201 This option enables a separate client device for IPC flood test 202 which can be used to flood the DSP with test IPCs and gather stats 203 about response times. 204 Say Y if you want to enable IPC flood test. 205 If unsure, select "N". 206 207config SND_SOC_SOF_DEBUG_IPC_FLOOD_TEST_NUM 208 int "Number of IPC flood test clients" 209 range 1 32 210 default 2 211 depends on SND_SOC_SOF_DEBUG_IPC_FLOOD_TEST 212 help 213 Select the number of IPC flood test clients to be created. 214 215config SND_SOC_SOF_DEBUG_IPC_MSG_INJECTOR 216 tristate "SOF enable IPC message injector" 217 select SND_SOC_SOF_CLIENT 218 help 219 This option enables the IPC message injector which can be used to send 220 crafted IPC messages to the DSP to test its robustness. 221 Say Y if you want to enable the IPC message injector. 222 If unsure, select "N". 223 224config SND_SOC_SOF_DEBUG_RETAIN_DSP_CONTEXT 225 bool "SOF retain DSP context on any FW exceptions" 226 help 227 This option keeps the DSP in D0 state so that firmware debug 228 information can be retained and dumped to userspace. 229 Say Y if you want to retain DSP context for FW exceptions. 230 If unsure, select "N". 231 232endif ## SND_SOC_SOF_DEBUG 233 234endif ## SND_SOC_SOF_DEVELOPER_SUPPORT 235 236config SND_SOC_SOF 237 tristate 238 select SND_SOC_TOPOLOGY 239 select SND_SOC_SOF_NOCODEC if SND_SOC_SOF_NOCODEC_SUPPORT 240 help 241 This option is not user-selectable but automagically handled by 242 'select' statements at a higher level. 243 The selection is made at the top level and does not exactly follow 244 module dependencies but since the module or built-in type is decided 245 at the top level it doesn't matter. 246 247config SND_SOC_SOF_PROBE_WORK_QUEUE 248 bool 249 help 250 This option is not user-selectable but automagically handled by 251 'select' statements at a higher level. 252 When selected, the probe is handled in two steps, for example to 253 avoid lockdeps if request_module is used in the probe. 254 255source "sound/soc/sof/amd/Kconfig" 256source "sound/soc/sof/imx/Kconfig" 257source "sound/soc/sof/intel/Kconfig" 258source "sound/soc/sof/mediatek/Kconfig" 259source "sound/soc/sof/xtensa/Kconfig" 260 261endif
