# Android Kernel Config Fragments
|
|
|
|
The files in these directories are meant to be used as a base for an Android
|
|
kernel config. All devices must have the options in `android-base.cfg` configured
|
|
as specified. If an `android-base-ARCH.cfg` file exists for the architecture of
|
|
your device, the options in that file must be configured as specified also.
|
|
|
|
While not mandatory, the options in `android-recommended.cfg` enable advanced
|
|
Android features.
|
|
|
|
Assuming you already have a minimalist defconfig for your device, a possible
|
|
way to enable these options would be to use the `merge_config.sh` script in the
|
|
kernel tree. From the root of the kernel tree:
|
|
|
|
```sh
|
|
ARCH=<arch> scripts/kconfig/merge_config.sh <...>/<device>_defconfig <...>/android-base.cfg <...>/android-base-<arch>.cfg <...>/android-recommended.cfg
|
|
```
|
|
|
|
This will generate a `.config` that can then be used to save a new defconfig or
|
|
compile a new kernel with Android features enabled.
|
|
|
|
Because there is no tool to consistently generate these config fragments,
|
|
lets keep them alphabetically sorted instead of random.
