I'm currently using a Pixel XL (marlin). This i tried to copy the android kernel config from the device. config Optional, can repeat. This documentation is intended to help OEMs optimize and configure Android If you still recall what we did in our last Android kernel fuzzing series: we built the kernel, slapped it onto the boot image, flashed it into the boot partition, restarted the Pixel kernel config file location in android. Many of the XML files are in the vendor partition, but they're read in the system If you are adding a new feature to AOSP which depends on a particular kernel configuration value, either that kernel configuration value must already be present in the base android config If you are adding a new feature to AOSP which depends on a particular kernel configuration value, either that kernel configuration value must already be present in the base android config This feature provides a way to separate the configuration parameters for Android user-space from those for the kernel. as IIRC, the Android build environment will copy the config file from another location in the tree and overwrite another config file.
