After a linux-yocto style kernel is configured, a kernel configuration audit is executed to detect common errors or issues with the config. This output used to be visible, but was made less obvious to not alarm users unnecessarily (since some configuration issues are acceptable). There are some classes of configuration issue that are worth being visible, and that is specified configuration values that do not make the final .config. These dropped options can result in any number of runtime failures, so flagging them at build time makes sense. The visibility of auditing is controlled by KCONF_AUDIT_LEVEL: 0: no reporting 1: report options that are specified, but not in the final config 2: report options that are not hardware related, but set by a BSP The default level is 1, with level 2 and above being for BSP development only. If these conditions are detected, warnings will be generated as follows: WARNING: [kernel config]: specified values did not make it into the kernel's final configuration: Value requested for CONFIG_SND_PCSP not in final ".config" Requested value: "CONFIG_SND_PCSP=y" Actual value set: "" or WARNING: [kernel config]: BSP specified non-hw configuration: CONFIG_BLOCK CONFIG_CFG80211_WEXT CONFIG_CORDIC CONFIG_CRC8 CONFIG_EFIVAR_FS CONFIG_EFI_PARTITION CONFIG_NET CONFIG_NETDEVICES CONFIG_PARTITION_ADVANCED CONFIG_WEXT_CORE CONFIG_WEXT_PROC CONFIG_WIRELESS At this point thse are only a warnings, since there needs to be time for layers and configuration fragments to be validated against this new check.
