hulk inclusion category: feature bugzilla: https://gitee.com/openeuler/kernel/issues/I8J6X4 CVE: NA
Reference: https://gitee.com/openeuler/kernel/pulls/286
-----------------------------------------
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.
``` Usage: make check_oedefconfig # # New options might needs to be updated to the default configuration # file. Use the following command: # 'make openeuler_defconfig/menuconfig/update_oedefconfig/save_oedefconfig' # !!! DO NOT EDIT !!! # # defconfig: arch/arm64/configs/openeuler_defconfig # CONFIG_MEMCG=n CONFIG_BLK_CGROUP=n CONFIG_CFS_BANDWIDTH=n CONFIG_RT_GROUP_SCHED=n CONFIG_CGROUP_PIDS=n CONFIG_CGROUP_RDMA=n CONFIG_CGROUP_FREEZER=n CONFIG_CGROUP_HUGETLB=n CONFIG_CPUSETS=n
make update_oedefconfig # Update openeuler_defconfig base on current source code
make save_oedefconfig # Save current .config to openeuler_defconfig' ```
If someone adds a new Kconfig, he should also explicitly update openeuler_defconfig, whether it's enabled or disabled.
Again, do *NOT* edit openeuler_defconfig directly.
