Changelog EronXCore GKI Kernel V6.6.139

EronXCore GKI Kernel V6.6.139 includes a Linux 6.6.139 update, Android 15 LTS compliance, and performance enhancements for gaming, with touch and thermal optimizations. Key features include bug fixes, improved CPU/GPU scaling, and advanced kernel root support. Reverts were made to unstable upstream changes, security patches applied for critical bugs, and improvements made for Android module compatibility and hardware safety.

General Updates:

• Kernel upgraded to Linux 6.6.139.

• Merged remote upstream branches including Linux stable and Android 15 LTS to maintain full Generic Kernel Image (GKI) compliance.

• Renamed build configuration layout target to EronXCore-5.2.

• Many bug fixes and stability improvements for Android GKI.

Gaming & Performance Overview:

This release is specifically tuned for high-performance gaming. Whether you're pushing frames in competitive shooters or looking for sustained thermal stability, EronXCore is built to handle the heat.

• Touch Response: Optimized sampling rates for lower input lag.

• Thermal Profiles: Aggressive heat management to prevent throttling during long sessions.

• Governor Tuning: Balanced for peak CPU/GPU output when under load.

Advanced ReSukiSU Root & Stealth Features:

• Integrated ReSukiSU: Switched to a powerful KernelSU-based root solution that includes built-in manager theme tweaks and custom SuSFS tool management.

• KPM Support: Retains streamlined KernelPatch Module (KPM) support while expanding APatch compatibility features.

• Integrated SusFS v2.1.0: Native root + latest integrity bypass patches.

• Multi-Manager Freedom: Universal design that allows standard Official KernelSU, RKSU, MKSU, or SukiSU manager apps to seamlessly control the kernel.

Performance & Memory Tweaks:

• fs/dcache: Decreased default vfs_cache_pressure to 60. This permits the VFS to hold directory and inode structures in cache longer, drastically reducing multi-tasking lag and micro-stutters.

• cpufreq: Overrode strict proprietary vendor policy limits inside __resolve_freq to unlock more responsive and accurate CPU frequency scaling controls.

Thermal Management & Reverts:

• Cleaned up experimental overhead by reverting the unstable "thermal: cpufreq_cooling: Force mitigation state to zero" logic to restore predictable thermal throttling behaviors.

• Reverted problematic KVM, SCSI, netfilter, and thermal upstream updates that were causing active system bugs.

Android Fixes:

• Preserved kernel API (task_struct) for complete out-of-tree Android module compatibility.

• Added critical structural exports for audio drivers (snd_soc) and system page memory allocators (dma_alloc/free_pages) to ensure external modules load safely.

CPU / Hardware Fixes:

• Fixed core hardware resource isolation issues on AMD Zen2 processors to ensure proper platform execution safety.

Debugging & Security Patches:

• Improved get_dumpable() logic implementation to enforce better debugging environment parameters and user-space security.

• Patched critical memory security bugs, including a severe buffer overflow vulnerability inside the Xen driver and a fatal double-free crash exploit.

• XFRM ESP: Prohibited in-place decryption tasks directly on shared fragments to eliminate potential wireless packet data corruption bugs.

TL;DR:

This kernel focuses on top-tier gaming performance, rock-solid stability, and advanced root stealth (ReSukiSU + SuSFS v2.1.0), while discarding risky upstream thermal modifications to keep your gameplay smooth and secure.
