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'
