Starting March 27, 2025, we recommend using android-latest-release instead of aosp-main to build and contribute to AOSP. For more information, see Changes to AOSP.
Test GKI modules
Stay organized with collections
Save and categorize content based on your preferences.
Test your GKI kernel and modules using the system_dlkm.img image and the
system_dlkm dynamic partition.
Before you can test using the development-only system_dlkm.img image built
from GKI kernel repository, you must disable the dm-verity security feature
to boot from the image. For further information on dm-verity, refer to
Implement dm-verity.
The system_dlkm.img image from kernel release artifacts is only for
development use and cannot be used to run CTS/VTS tests or use in the
production. To run CTS/VTS tests, you need to use the production images and
signed modules from the system_dlkm_staging_archive.tar.gz archive in the
kernel artifacts. You can build the system_dlkm partition image as described
in Implement a GKI module
partition.
