A kernel carefully optimized for

• low-memory, and performance
• small power savings

Speciifically crafted (and tested) for 4GB variant in mind ❤️

• Supports tapas/topaz/sapphire/sapphiren ⭐

XDA Forums thread | SourceForge mirror

Power Efficiency:

• wakelock tweaks, boeffla WB, forced lazy RCU,
  power-efficient workqueues, kernel power optimizations.

Performance:

• tuned SSG I/O scheduler, tuned memory management for 4GB, CASS,
  westwood (default) + BBR TCP,, force disabled kasan, baseband-guard,
  various kernel changes, and OnePlus/Xiaomi optimizations.

3 variants:

• Vanilla, KSUN, KSUN+SuSFS

kernel: staging: refactored broken binder_prio driver
kernel: cpu: fix misconfigured mi_thermald
kernel: mm: merged refactored kshrink_slabd optimization from oneplus
kernel: mm: increase swappiness a bit
kernel: net: shed off some unused qdiscs
kernel: small changes and bug fixes

compiler: use mlgo+regalloc
compiler: fix the soc+instruction optimization hint

ack: merged android13-5.15-2025-09 tag (5.15.189)
kernelsu: updated to 12892 (latest)
susfs: updated to 1.5.12 (latest)
ssg: merged update from S918BXXU3CXCF
baseband-guard: imported bbg to prevent hard-bricks

This is a stable 5.15.189 release built with latest clang-20.0.0 (-O3+MLGO+Polly+Release-Regalloc)

Installation guide:

1. Download the kernel zip below
2. Use FKM flasher, or reboot to recovery and install it
3. Enjoy
