The culmination of a long journey: a fully backported BPF subsystem and rock-solid stability.
This is the Hybrid_Neo v1.6.5 LTS "Charred Weasel" release, marking the final point of a massive effort to modernize the kernel for Xiaomi Mi Max 3 (nitrogen). This release transforms the base Android 4.6 kernel into a modern, secure, and feature-rich platform, ready for the latest Android versions.
Key Highlights of this Release
· Full BPF Backport (4.7 -> 4.19): The entire BPF (Berkeley Packet Filter) subsystem has been meticulously ported from version 4.7 all the way to 4.19. This includes all modern BPF map types, program types, the BPF Type Format (BTF) for debugging, and the advanced verifier. This ensures full compatibility with modern Android network traffic monitoring and security features.
· Unwavering Stability: The foundation of the kernel has been consolidated with all upstream security patches and critical fixes merged directly from the Linux 4.6 LTS branch, culminating in version 4.6.8.
· Proven Compatibility: The kernel is tested and working on Android 11 through Android 16 (GSI). While some A16 GSIs with incompatible vendor partitions may have issues, the kernel itself is fully prepared for the task.
· Fixed Fast Charge: A long-standing bug in the force fast charge driver has been fixed. The device now correctly utilizes its full 16W charging capability without user intervention, by tying the feature to its kernel config flag.
· Security & Control: Includes KernelSU-Next for modern root management, while the SUSFS module has been disabled in this build to ensure a clean and stable base.
This is more than just a kernel. It is a statement that old hardware, combined with the will to create and the right tools, can still be relevant and powerful.
Full Changelog:
· Merged all upstream Linux 4.6.x LTS versions (4.6.1 to 4.6.8).
· Sequentially backported the BPF subsystem: 4.7, 4.8, 4.9, 4.10, 4.11, 4.12, 4.13, 4.14, 4.15, 4.16, 4.17, 4.18, and finally 4.19.
· Adapted the scheduler by backporting old governors from Linux 4.10.
· Fixed resource handling and x86/kallsyms compilation.
· Updated SUSFS to v1.2.2 and later disabled it for stability.
· Fixed a critical bug in the force fast charge driver.
· Integrated KernelSU-Next v12851.
