.config file

[Jingwen Ye]

Hi, everyone

After I ran the following command to modify the module of kernel config

./chromeos/scripts/kernelconfig editconfig

I want to find the difference between .config and .config.old but I cannot find where the .config is. I knew there are 3 config files for Chromium-x86_64 and the make command will combine 3 seperated configs into one config. After checked prepareconfig scripts I found where 3 seperated configs are (base/common/chromiumos.config), but still cannot find the combined version.

If you want to see the "generated" config (i.e., the combination of the pieces of the "split" config) you can run the "genconfig" subcommand.

Or you can run through a full kernel build and look for something like:

/build/${BOARD}/var/cache/portage/sys-kernel/chromeos-kernel-X_Y/.config
