This is typically only 74 enabled for developers or devices where the sound card is 75 controlled externally. 76 This option is mutually exclusive with the Intel HDAudio support. 77 Selecting it may have negative impacts and prevent e.g. microphone 78 functionality from being enabled on Intel CoffeeLake and later 79 platforms. 80 Distributions should not select this option! 81 Say Y if you need this nocodec fallback option. 82 If unsure select "N". 83 84config SND_SOC_SOF_STRICT_ABI_CHECKS 85 bool "SOF strict ABI checks" 86 help 87 This option enables strict ABI checks for firmware and topology 88 files. 89 When these files are more recent than the kernel, the kernel 90 will handle the functionality it supports and may report errors 91 during topology creation or run-time usage if new functionality 92 is invoked. 93 This option will stop topology creation and firmware load upfront. 94 It is intended for SOF CI/releases and not for users or distros. 95 Say Y if you want strict ABI checks for an SOF release. 96 If you are not involved in SOF releases and CI development, 97 select "N". 98 99config SND_SOC_SOF_DEBUG 100 bool "SOF debugging features" 101 help 102 This option can be used to enable or disable individual SOF firmware 103 and driver debugging options. 104 Say Y if you are debugging SOF FW or drivers. 105 If unsure select "N". 106 107if SND_SOC_SOF_DEBUG 108 109config SND_SOC_SOF_FORCE_NOCODEC_MODE 110 bool "SOF force nocodec Mode" 111 depends on SND_SOC_SOF_NOCODEC_SUPPORT 112 help 113 This forces SOF to use dummy/nocodec as machine driver, even 114 though there is a codec detected on the real platform. This is 115 typically only enabled for developers for debug purposes, before 116 codec/machine driver is ready, or to exclude the impact of those 117 drivers. 118 Say Y if you need this force nocodec mode option. 119 If unsure select "N". 120 121config SND_SOC_SOF_DEBUG_XRUN_STOP 122 bool "SOF stop on XRUN" 123 help 124 This option forces PCMs to stop on any XRUN event.

This is useful 134 if you are trying to debug IPC with the DSP firmware. 135 If unsure select "N". 136 137config SND_SOC_SOF_DEBUG_FORCE_IPC_POSITION 138 bool "SOF force to use IPC for position update on SKL+" 139 help 140 This option forces to handle stream position update IPCs and run PCM 141 elapse to inform ALSA about that, on platforms (e.g. Intel SKL+) that 142 with other approach (e.g. HDAC DPIB/posbuf) to elapse PCM. 143 On platforms (e.g. Intel SKL-) where position update IPC is the only 144 one choice, this setting won't impact anything. 145 If you are trying to debug pointer update with position IPCs or where 146 DPIB/posbuf is not ready, select "Y". 147 If unsure select "N". 148 149config SND_SOC_SOF_DEBUG_ENABLE_DEBUGFS_CACHE 150 bool "SOF enable debugfs caching" 151 help 152 This option enables caching of debugfs 153 memory -> DSP resource (memory, register, etc) 154 before the audio DSP is suspended. This will increase the suspend 155 latency and therefore should be used for debug purposes only. 156 Say Y if you want to enable caching the memory windows. 157 If unsure, select "N". 158 159config SND_SOC_SOF_DEBUG_ENABLE_FIRMWARE_TRACE 160 bool "SOF enable firmware trace" 161 help 162 The firmware trace can be enabled either at build-time with 163 this option, or dynamically by setting flags in the SOF core 164 module parameter (similar to dynamic debug). 165 If unsure, select "N". 166 167config SND_SOC_SOF_DEBUG_IPC_FLOOD_TEST 168 bool "SOF enable IPC flood test" 169 help 170 This option enables the IPC flood test which can be used to flood 171 the DSP with test IPCs and gather stats about response times. 172 Say Y if you want to enable IPC flood test. 173 If unsure, select "N". 174 175config SND_SOC_SOF_DEBUG_RETAIN_DSP_CONTEXT 176 bool "SOF retain DSP context on any FW exceptions" 177 help 178 This option keeps the DSP in D0 state so that firmware debug 179 information can be retained and dumped to userspace. 180 Say Y if you want to retain DSP context for FW exceptions. 181 If unsure, select "N". 182 183endif ## SND_SOC_SOF_DEBUG 184 185endif ## SND_SOC_SOF_DEVELOPER_SUPPORT 186 187config SND_SOC_SOF 188 tristate 189 select SND_SOC_TOPOLOGY 190 select SND_SOC_SOF_NOCODEC if SND_SOC_SOF_NOCODEC_SUPPORT 191 help 192 This option is not user-selectable but automagically handled by 193 'select' statements at a higher level. 194 The selection is made at the top level and does not exactly follow 195 module dependencies but since the module or built-in type is decided 196 at the top level it doesn't matter. 197 198config SND_SOC_SOF_PROBE_WORK_QUEUE 199 bool 200 help 201 This option is not user-selectable but automagically handled by 202 'select' statements at a higher level. 203 When selected, the probe is handled in two steps, for example to 204 avoid lockdeps if request_module is used in the probe. 205 206source "sound/soc/sof/imx/Kconfig" 207source "sound/soc/sof/intel/Kconfig" 208source "sound/soc/sof/xtensa/Kconfig" 209 210endif 211
