What’s New in Nerotuno Kernel v1.0?
Linux Kernel Upstream
The kernel has been updated to Linux Kernel 5.10.252, bringing upstream bug fixes, security improvements, and better overall system stability.
Latest CodeLinaro Platform Updates
Nerotuno Kernel merges the latest CodeLinaro KERNEL.PLATFORM.1.0.r3-07400-kernel.0 changes, improving compatibility with Qualcomm hardware and enhancing kernel reliability.
BBR TCP Congestion Control
The default TCP congestion algorithm has been switched to BBR, helping improve network throughput, reduce latency, and deliver smoother online performance during downloads, streaming, and gaming.
Lower System Latency
Kernel Page Table Isolation (KPTI) has been disabled to reduce syscall latency, resulting in faster UI interactions and improved overall responsiveness.
Memory Optimization
LMKD (Low Memory Killer Daemon) and pressure handling have been tuned specifically for both 6GB and 8GB RAM variants, helping improve multitasking and reducing unnecessary background process termination.
GPU Improvements
The GPU idle timeout has been reduced to 58 milliseconds, providing a better balance between graphics responsiveness and power efficiency.
Improved ZRAM Performance
ZRAM compression and memory handling have been optimized, improving memory efficiency and helping maintain smooth performance during heavy multitasking.
System Optimization
Several additional performance optimizations and stability improvements have been included throughout the kernel to deliver a smoother user experience.
Built with LLVM Clang 19
The kernel is compiled using LLVM Clang 19, providing modern compiler optimizations for improved performance and efficiency.

Final Thoughts
Nerotuno Kernel v1.0 is a performance-oriented custom kernel designed for AOSP-based Android 15 and Android 16 ROMs on the Redmi Note 13 Pro 5G. By combining Linux 5.10.252, Qualcomm CodeLinaro updates, BBR networking, optimized memory management, GPU tuning, and LLVM Clang 19, it delivers noticeable improvements in responsiveness, multitasking, and overall system stability.
The inclusion of KernelSU-Next and Full LTO makes it an attractive choice for power users, but it is important to remember that this kernel is not compatible with MIUI, HyperOS, or HyperOS Port ROMs. Ensure you’re using a supported AOSP ROM before flashing and always create a complete backup to avoid data loss.
