Hi everybody,
I updated Kconfig to track latest Linux last week and that brought some behavioral change with it. While these changes are appreciated in some respect, they also complicate work in others.
I now proposed https://review.coreboot.org/79298, a change that exempts _all_ *config targets from strict symbol checking under the assumption that any attempt to edit a config should work even if the old configuration is unclean. It will save a clean copy if it saves on exit.
A regular build will still fail with an error like this:
/home/pgeorgi/coreboot/.config:152:warning: unknown symbol: VBT_DATA_SIZE_KB
ERROR: 1 warnings encountered, and warnings are errors.
make[1]: *** [build/util/kconfig/Makefile.real:76: olddefconfig] Error 1 make: *** [Makefile:219: build/config.h] Error 2
Running `make olddefconfig` manually (that is, explicitly stating that you want to run the command) would clean it up.
Now, given that this is a rather big semantic change, I wanted to make sure that the wider community can provide their input on how to approach this issue properly.
Before last week, only `make oldconfig` was exempt from checking, and the checks made by the other *config targets were much more lenient. With this approach, all *config targets clean up the config (and will do so silently, which might be a concern!) but when the config isn't right, the build will fail, and loudly.
Thoughts?
Regards, Patrick
