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 96 config SND_SOC_SOF_NOCODEC 97 tristate 98 99 config SND_SOC_SOF_NOCODEC_SUPPORT 100 bool "SOF nocodec static 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 at build time 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". 113 114 config 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". 128 129 config SND_SOC_SOF_ALLOW_FALLBACK_TO_NEWER_IPC_VERSION 130 bool "SOF allow fallback to newer IPC version" 131 help 132 This option will allow the kernel to try to 'fallback' to a newer IPC 133 version if there are missing firmware files to satisfy the default IPC 134 version. 135 IPC version fallback to older versions is not affected by this option, 136 it is always available. 137 Say Y if you are involved in SOF development and need this option. 138 If not, select N. 139 140 config SND_SOC_SOF_DEBUG 141 bool "SOF debugging features" 142 help 143 This option can be used to enable or disable individual SOF firmware 144 and driver debugging options. 145 Say Y if you are debugging SOF FW or drivers. 146 If unsure select "N". 147 148 if SND_SOC_SOF_DEBUG 149 150 config SND_SOC_SOF_NOCODEC_DEBUG_SUPPORT 151 bool "SOF nocodec debug mode support" 152 depends on !SND_SOC_SOF_NOCODEC_SUPPORT 153 help 154 This adds support for a dummy/nocodec machine driver fallback 155 option. 156 Unlike the SND_SOC_SOF_NOCODEC_SUPPORT, this option is NOT 157 mutually exclusive at build with the Intel HDAudio support.

This is 169 typically only enabled for developers for debug purposes, before 170 codec/machine driver is ready, or to exclude the impact of those 171 drivers. 172 Say Y if you need this force nocodec mode option. 173 If unsure select "N". 174 175 config SND_SOC_SOF_DEBUG_XRUN_STOP 176 bool "SOF stop on XRUN" 177 help 178 This option forces PCMs to stop on any XRUN event. This is useful to 179 preserve any trace data and pipeline status prior to the XRUN. 180 Say Y if you are debugging SOF FW pipeline XRUNs. 181 If unsure select "N". 182 183 config SND_SOC_SOF_DEBUG_VERBOSE_IPC 184 bool "SOF verbose IPC logs" 185 help 186 This option enables more verbose IPC logs, with command types in 187 human-readable form instead of just 32-bit hex dumps. This is useful 188 if you are trying to debug IPC with the DSP firmware. 189 If unsure select "N". 190 191 config SND_SOC_SOF_DEBUG_FORCE_IPC_POSITION 192 bool "SOF force to use IPC for position update on SKL+" 193 help 194 This option forces to handle stream position update IPCs and run PCM 195 elapse to inform ALSA about that, on platforms (e.g. Intel SKL+) that 196 with other approach (e.g. HDAC DPIB/posbuf) to elapse PCM. 197 On platforms (e.g. Intel SKL-) where position update IPC is the only 198 one choice, this setting won't impact anything. 199 If you are trying to debug pointer update with position IPCs or where 200 DPIB/posbuf is not ready, select "Y". 201 If unsure select "N". 202 203 config SND_SOC_SOF_DEBUG_ENABLE_DEBUGFS_CACHE 204 bool "SOF enable debugfs caching" 205 help 206 This option enables caching of debugfs 207 memory -> DSP resource (memory, register, etc) 208 before the audio DSP is suspended. This will increase the suspend 209 latency and therefore should be used for debug purposes only. 210 Say Y if you want to enable caching the memory windows. 211 If unsure, select "N". 212 213 config SND_SOC_SOF_DEBUG_ENABLE_FIRMWARE_TRACE 214 bool "SOF enable firmware trace" 215 help 216 The firmware trace can be enabled either at build-time with 217 this option, or dynamically by setting flags in the SOF core 218 module parameter (similar to dynamic debug). 219 If unsure, select "N". 220 221 config SND_SOC_SOF_DEBUG_IPC_FLOOD_TEST 222 tristate "SOF enable IPC flood test" 223 depends on SND_SOC_SOF 224 select SND_SOC_SOF_CLIENT 225 help 226 This option enables a separate client device for IPC flood test 227 which can be used to flood the DSP with test IPCs and gather stats 228 about response times. 229 Say Y if you want to enable IPC flood test. 230 If unsure, select "N". 231 232 config SND_SOC_SOF_DEBUG_IPC_FLOOD_TEST_NUM 233 int "Number of IPC flood test clients" 234 range 1 32 235 default 2 236 depends on SND_SOC_SOF_DEBUG_IPC_FLOOD_TEST 237 help 238 Select the number of IPC flood test clients to be created. 239 240 config SND_SOC_SOF_DEBUG_IPC_MSG_INJECTOR 241 tristate "SOF enable IPC message injector" 242 depends on SND_SOC_SOF 243 select SND_SOC_SOF_CLIENT 244 help 245 This option enables the IPC message injector which can be used to send 246 crafted IPC messages to the DSP to test its robustness. 247 Say Y if you want to enable the IPC message injector. 248 If unsure, select "N". 249 250 config SND_SOC_SOF_DEBUG_IPC_KERNEL_INJECTOR 251 tristate "SOF enable IPC kernel injector" 252 depends on SND_SOC_SOF 253 select SND_SOC_SOF_CLIENT 254 help 255 This option enables the IPC kernel injector which can be used to send 256 crafted IPC messages to the kernel to test its robustness against 257 DSP messages. 258 Say Y if you want to enable the IPC kernel injector. 259 If unsure, select "N". 260 261 config SND_SOC_SOF_DEBUG_RETAIN_DSP_CONTEXT 262 bool "SOF retain DSP context on any FW exceptions" 263 help 264 This option keeps the DSP in D0 state so that firmware debug 265 information can be retained and dumped to userspace. 266 Say Y if you want to retain DSP context for FW exceptions. 267 If unsure, select "N". 268 269 endif ## SND_SOC_SOF_DEBUG 270 271 endif ## SND_SOC_SOF_DEVELOPER_SUPPORT 272 273 config SND_SOC_SOF 274 tristate 275 select SND_SOC_TOPOLOGY 276 select SND_SOC_SOF_NOCODEC if SND_SOC_SOF_NOCODEC_SUPPORT 277 select SND_SOC_SOF_NOCODEC if SND_SOC_SOF_NOCODEC_DEBUG_SUPPORT 278 help 279 This option is not user-selectable but automagically handled by 280 'select' statements at a higher level. 281 The selection is made at the top level and does not exactly follow 282 module dependencies but since the module or built-in type is decided 283 at the top level it doesn't matter. 284 285 config SND_SOC_SOF_PROBE_WORK_QUEUE 286 bool 287 help 288 This option is not user-selectable but automagically handled by 289 'select' statements at a higher level. 290 When selected, the probe is handled in two steps, for example to 291 avoid lockdeps if request_module is used in the probe. 292 293 # Supported IPC versions 294 config SND_SOC_SOF_IPC3 295 bool 296 297 config SND_SOC_SOF_IPC4 298 bool 299 300 source "sound/soc/sof/amd/Kconfig" 301 source "sound/soc/sof/imx/Kconfig" 302 source "sound/soc/sof/intel/Kconfig" 303 source "sound/soc/sof/mediatek/Kconfig" 304 source "sound/soc/sof/xtensa/Kconfig" 305 306 endif
