It would be cool if there were a command I can run so that I can enable all those. Example:
$ grep CONFIG_VMLINUX_VALIDATION .config $ ./scripts/config --enable CONFIG_VMLINUX_VALIDATION $ grep CONFIG_VMLINUX_VALIDATION .config CONFIG_VMLINUX_VALIDATION=y $ make oldconfig # # configuration written to .config # $ grep CONFIG_VMLINUX_VALIDATION .config $
Needs other options.
Maybe you could create a .config snippet which we can merge with scripts/kconfig/merge_config.sh... or maybe start from arch/x86/configs/x86_64_defconfig, add all those and call it
arch/x86/configs/x86_64_testconfig
or so.
