[PATCH OLK-6.6 v2 0/3] Add initial openeuler_defconfig for arm64 and
by Zheng Zengkai 21 Nov '23

21 Nov '23

If new options are introduced, but openeuler_defconfig is not explicitly configured, the actual compiled version may be configured according to the default settings, which may be different from the author's expectation. Therefore, some commands/scripts are added to help developers to check and update the defconfig. It is also convenient for continuous integration tools to check the consistency of defconfig. Based on OLK-5.10 openeuler_defconfig, use the commands mentioned above to generate the initial openeuler_defconfig for OLK-6.6 kernel build.
