This is typically only 90 enabled for developers or devices where the sound card is 91 controlled externally. 92 This option is mutually exclusive with the Intel HDAudio support. 93 Selecting it may have negative impacts and prevent e.g. microphone 94 functionality from being enabled on Intel CoffeeLake and later 95 platforms. 96 Distributions should not select this option! 97 Say Y if you need this nocodec fallback option. 98 If unsure select "N". 99 100config SND_SOC_SOF_STRICT_ABI_CHECKS 101 bool "SOF strict ABI checks" 102 help 103 This option enables strict ABI checks for firmware and topology 104 files. 105 When these files are more recent than the kernel, the kernel 106 will handle the functionality it supports and may report errors 107 during topology creation or run-time usage if new functionality 108 is invoked. 109 This option will stop topology creation and firmware load upfront. 110 It is intended for SOF CI/releases and not for users or distros. 111 Say Y if you want strict ABI checks for an SOF release. 112 If you are not involved in SOF releases and CI development, 113 select "N". 114 115config SND_SOC_SOF_DEBUG 116 bool "SOF debugging features" 117 help 118 This option can be used to enable or disable individual SOF firmware 119 and driver debugging options. 120 Say Y if you are debugging SOF FW or drivers. 121 If unsure select "N". 122 123if SND_SOC_SOF_DEBUG 124 125config SND_SOC_SOF_FORCE_NOCODEC_MODE 126 bool "SOF force nocodec Mode" 127 depends on SND_SOC_SOF_NOCODEC_SUPPORT 128 help 129 This forces SOF to use dummy/nocodec as machine driver, even 130 though there is a codec detected on the real platform. This is 131 typically only enabled for developers for debug purposes, before 132 codec/machine driver is ready, or to exclude the impact of those 133 drivers. 134 Say Y if you need this force nocodec mode option. 135 If unsure select "N". 136 137config SND_SOC_SOF_DEBUG_XRUN_STOP 138 bool "SOF stop on XRUN" 139 help 140 This option forces PCMs to stop on any XRUN event.
