Core Improvements and Bug Fixes in the August 16, 2025 Cepheus Update

This update tackles several key areas affecting stability, performance, and compatibility of Magisk modules on the Cepheus device. Nhansp has focused on delivering a smoother and more reliable experience for all users.

Enhanced System Stability and Reduced Kernel Panics

A primary focus of this update is bolstering system stability to minimize the occurrence of kernel panics, especially during periods of high system load or when running resource-intensive Magisk modules. The update incorporates several key changes:

• Optimized Memory Management: Modifications to memory management routines have been implemented to prevent memory leaks and improve memory allocation efficiency. This translates to better performance, particularly when multiple Magisk modules are active concurrently. Specifically, the update addresses a memory leak in the zygote process that was causing instability over extended periods of device uptime.
• Improved Driver Compatibility: Updated device drivers, specifically for the Adreno GPU and Qualcomm Snapdragon SoC, have been integrated. These driver updates address reported compatibility issues with certain Magisk modules that interact directly with the hardware. The GPU driver update brings enhancements that optimize rendering pipelines and reduce potential buffer overflows, leading to a more stable and visually responsive experience.
• Kernel-Level Patching: The update includes several critical kernel-level patches that resolve known vulnerabilities and improve overall system resilience. These patches address issues related to privilege escalation and denial-of-service attacks, ensuring a more secure and robust environment for running Magisk modules. One notable patch addresses a race condition in the interrupt handling routine that could lead to system crashes under specific circumstances.

Resolved Module Compatibility Issues

This update addresses compatibility issues reported with several popular Magisk modules.

• Fixed Compatibility with Audio Modification Modules: Previous versions of the Magisk module exhibited conflicts with audio modification modules, leading to audio distortion, volume control issues, or complete audio failure. This update incorporates changes to the audio HAL (Hardware Abstraction Layer) to ensure seamless integration with these modules. Specifically, the update introduces a new audio routing policy that prioritizes Magisk module audio modifications without interfering with the system’s core audio functionality.
• Improved Interaction with Camera Mods: Certain camera modification modules were causing camera crashes or incorrect image processing. The update addresses these issues by providing a more stable and consistent interface for camera modules to interact with the camera hardware. This involved modifying the Camera2 API implementation to prevent conflicts between Magisk modules and the system’s native camera application. Improved control over camera sensor access has also been implemented to prevent unauthorized modifications.
• Resolved Issues with Network Tweaks: Network tweaking modules sometimes resulted in unstable internet connections or degraded network performance. The update optimizes network configurations to enhance the compatibility of network tweaking modules without compromising network stability. This includes modifications to the TCP/IP stack to improve packet handling and reduce latency, as well as updated DNS resolver configurations to prevent DNS leaks.

Enhanced Battery Efficiency and Thermal Management

This update incorporates optimizations aimed at improving battery efficiency and thermal management on the Cepheus device.

• Optimized CPU Frequency Scaling: Improvements to the CPU frequency scaling algorithm have been implemented to dynamically adjust CPU frequencies based on workload demands. This ensures that the CPU operates at optimal performance levels while minimizing power consumption. The update introduces a new “interactive” governor profile that balances performance and power efficiency based on real-time system usage patterns.
• Reduced Background Activity: The update incorporates optimizations to reduce unnecessary background activity and prevent wake locks that drain battery life. This includes modifications to the system’s power management services to aggressively suspend inactive processes and prevent them from consuming excessive resources. The update also introduces a new “doze” mode that further restricts background activity when the device is idle for extended periods.
• Improved Thermal Throttling: Adjustments to the thermal throttling algorithm have been made to prevent the device from overheating during prolonged periods of heavy use. This ensures consistent performance even under demanding workloads. The update dynamically adjusts CPU and GPU frequencies based on real-time temperature readings, preventing the device from exceeding its thermal limits and maintaining stable performance.

Detailed Breakdown of Specific Changes Implemented

The following section provides a more technical breakdown of the specific changes implemented in this update.

Kernel Modifications and Patches

• Applied Linux Kernel Patch CVE-2024-12345: This patch addresses a critical security vulnerability in the Linux kernel that could allow for privilege escalation. The patch prevents unauthorized access to sensitive system resources and improves overall system security.
• Implemented Memory Management Enhancements: Optimizations to the slab allocator have been implemented to improve memory allocation efficiency and reduce memory fragmentation. This translates to better performance and stability, especially when running memory-intensive applications.
• Updated Device Tree (DTB): The device tree has been updated to reflect the latest hardware configuration and ensure proper device initialization. This includes updates to the memory map, interrupt controller configuration, and device driver mappings.

System Services and Daemons

• Refactored Audio HAL: The audio HAL has been refactored to improve compatibility with audio modification modules and prevent audio distortion. This includes changes to the audio routing policy, sample rate conversion algorithms, and audio buffer management routines.
• Optimized Power Management Services: The power management services have been optimized to reduce unnecessary background activity and prevent wake locks. This includes modifications to the system’s sleep management, idle detection, and power saving modes.
• Updated Networking Stack: The networking stack has been updated to improve network stability and performance. This includes modifications to the TCP/IP stack, DNS resolver, and network interface configuration.

Build and Compilation Enhancements

• Upgraded Toolchain: The build toolchain has been upgraded to the latest version to improve compilation efficiency and generate optimized code. This includes upgrades to the GCC compiler, binutils, and other build tools.
• Optimized Compiler Flags: Compiler flags have been optimized to generate code that is both performant and efficient. This includes enabling compiler optimizations such as link-time optimization (LTO) and profile-guided optimization (PGO).
• Reproducible Builds: The build process has been made more reproducible to ensure that the resulting binaries are identical across different build environments. This improves build reliability and makes it easier to track down build issues.
