android13-5.15 Release Builds

Stay organized with collections Save and categorize content based on your preferences.

This article provides a monthly listing of GKI release builds for android13-5.15. 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 13 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 Android13-5.15 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 := 13
BOOT_SECURITY_PATCH := 2022-07-05

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

Prop: com.android.build.boot.os_version -> '13'
Prop: com.android.build.boot.security_patch -> '2022-07-05'

Artifact file description

The following tables describe the files contained in the artifacts. See the description of each file to download the file you need.

Kernel artifacts

File name Description
Image The kernel image binary.
Image.lz4 The kernel image binary compressed blz4.
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.
modules.builtin A list of all modules built into the kernel, used by modprobe. Needed for mixed builds.
modules.builtin.modinfo Contains the modinfo (refer to `modinfo(8)`) of the entries in modules.builtin. Needed for mixed builds.
