Changelog EronXCore GKI Kernel V6.6.139

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.

• KernelSU-Next: Integrated support for seamless root management.

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 stability, Android compatibility, critical bug fixes, and security, while reverting some risky features to keep the system safe.
