Hello. I've been trying to add some configurations for device drivers that I need to work with.
Since, changing .config file is just a temporary thing, I wanted to add some configurations directly on ~/hikey_linaro/arch/arm64/configs/hikey_defconfig file.
I found out that for some configurations, it is automatically added to .config file as I compile the hikey kernel.
However, some other configurations, they are not added to .config after compilation.
For instance, currently I'm trying to add CONFIG_VIDEOBUF2_VMALLOC and CONFIG_USB_PHY.
I cannot find those in .config file even after I run those two commands.
- make ARCH=arm64 hikey_defconfig
- make ARCH=arm64 CROSS_COMPILE=aarch64-linux-android- -j24
Does anyone know how .config file is generated? (I could not find any useful sources on other websites.)
Moreover, could anyone also suggest a way to make those configurations to be generated into .config file?
Thank you in advance for your help!
