This feature profile enables the debug USE flag for every chromeos-kernel package. It is intended to be used for CrOS automated debug kernel testing.
Debug kernel testing is designed to uncover bugs that are hidden in our regularly tested kernel which is optimized for performance. Enabling the kernel debug flag will turn on necessary assertions and debug options to expose such bugs.
To add a debug kernel profile to an existing overlay, take the following steps:
../base chromiumos:features/kernel/debug
The first line specifies that the new profile will inherit from the overlay's base profile. The second line will mix in this debug feature profile which enables the debug USE flag for the chromeos-kernel package, independent of which kernel version the overlay uses.
