Q: How is the bb.org_defconfig maintained? #220

Closed fgervais closed 4 years ago

fgervais commented 4 years ago

I'm using the bb.org_defconfig as a base for a project similar to the beagleboard but I'm aiming for a minimal config, specific to our needs.

What I noticed is that bb.org_defconfig makes a really good job at specifying only the options that differs from the defaults. Also even if it's a file containing cherry-picked configs, it maintains the proper order of configs.

Is it all done manually or there is a special trick to achieve this?

Is the person maintaining this file manually figuring out if a config is default or not and manually inserting it at the correct position? I know this is what I'm doing right now, that's is why I am curious if there is something better :).

@fgervais , i cheat and use savedefconfig, right before it's pushed..

cp ${DIR}/patches/defconfig ${DIR}/KERNEL/.config
make ARCH=${KERNEL_ARCH} savedefconfig
cp ${DIR}/KERNEL/defconfig ${DIR}/KERNEL/arch/${KERNEL_ARCH}/configs/${example}_defconfig
${git_bin} add arch/${KERNEL_ARCH}/configs/${example}_defconfig

Regards,

Well I'm glad I asked. I didn't know about this savedefconfig even though it seems it's been there for a while. Thanks @RobertCNelson.
