This is typically only 65 enabled for developers or devices where the sound card is 66 controlled externally 67 This option is mutually exclusive with the Intel HDaudio support, 68 selecting it may have negative impacts and prevent e.g. microphone 69 functionality from being enabled on Intel CoffeeLake and later 70 platforms. 71 Distributions should not select this option! 72 Say Y if you need this nocodec fallback option 73 If unsure select "N". 74 75config SND_SOC_SOF_STRICT_ABI_CHECKS 76 bool "SOF strict ABI checks" 77 help 78 This option enables strict ABI checks for firmware and topology 79 files. 80 When these files are more recent than the kernel, the kernel 81 will handle the functionality it supports and may report errors 82 during topology creation or run-time usage if new functionality 83 is invoked. 84 This option will stop topology creation and firmware load upfront. 85 It is intended for SOF CI/releases and not for users or distros. 86 Say Y if you want strict ABI checks for an SOF release 87 If you are not involved in SOF releases and CI development 88 select "N". 89 90config SND_SOC_SOF_DEBUG 91 bool "SOF debugging features" 92 help 93 This option can be used to enable or disable individual SOF firmware 94 and driver debugging options. 95 Say Y if you are debugging SOF FW or drivers. 96 If unsure select "N". 97 98if SND_SOC_SOF_DEBUG 99 100config SND_SOC_SOF_FORCE_NOCODEC_MODE 101 bool "SOF force nocodec Mode" 102 depends on SND_SOC_SOF_NOCODEC_SUPPORT 103 help 104 This forces SOF to use dummy/nocodec as machine driver, even 105 though there is a codec detected on the real platform.
