android14-5.15 Release Builds

This article provides a monthly listing of GKI release builds for android14-5.15. The links in the artifacts column display the list of kernel or debug kernel artifacts in the respective release. To find a specific file, see the list of artifact definitions.

If you have questions about these builds, file a bug in the Issue Tracker.

Stages of release branches

Certified builds support partner-requested respins for up to a maximum of six months. After six months, a partner can request a respin to receive the security patches mentioned in the Android Security Bulletin (ASB).

When the LTS requirements cause the branch to be non-compliant, the branch is deprecated. Respin requests for deprecated branches aren't accepted.

For additional detail, reference Emergency respin process.

Boot image OS version and SPL

For the Android 14 GKI boot-*.img, the os_version field, that holds the OS version and SPL in the bootimg.h header file, is set to zero. See android14-5.15 to get the Tag and SPL information for each GKI release. When incorporating a GKI prebuilt boot.img, device partners can put the information into the AVB footer by setting BOOT_OS_VERSION and BOOT_SECURITY_PATCH, shown as follows:

BOOT_OS_VERSION := 14
BOOT_SECURITY_PATCH := 2023-07-05

The build appends the following AVB properties into a prebuilt boot.img:

Prop: com.android.build.boot.os_version -> '14'
Prop: com.android.build.boot.security_patch -> '2023-07-05'

Artifact file description

boot-lz4.img The boot image with lz4 compressed kernel.
signed/certified-boot-img-$BID.tar.gz Contains all certified boot images (only on certified builds).
System.map A lookup table between symbols and their addresses in memory. Needed for mixed builds.
manifest_$BID.xml The pinned repo manifest file which can sync the source code for building the kernel.
