Stability , performance, multi tasking, battery optimizations, etc

User-Friendly Changelog

⚡ Performance Improvements

  • Enhanced task scheduling with better load distribution across big.LITTLE cores.
  • Optimized CPU frequency scaling for smoother transitions and improved responsiveness.
  • Faster system ramp-up, especially noticeable on 90Hz displays.
  • Improved LZ4 decompression with ARM64 assembly for faster and more efficient compression.
  • Reduced scheduler slice granularity for more fluid multitasking.
  • Reworked task balancing logic: tasks stay on idle CPUs or are migrated more intelligently.
  • Enabled PELT (Per-Entity Load Tracking) for better scheduling precision.
  • Multiple micro-optimizations to remove redundant spinlocks, acquire barriers, and queue scanning.
  • Improved scheduler wakeups to reduce CPU contention.
  • Improved I/O performance by disabling I/O stats overhead.
  • Fast ramp-up of CPU utilization using EWMA for smoother user interaction.
  • Lowered minimal imbalance threshold in load balancing.

🔋 Power Management & Sleep Enhancements

  • Switched to the new TEO governor for more efficient idle state management.
  • Asynchronous suspend/resume support added for multiple components (UFS, rotator, IPA).
  • Lowered latency requirements and fixed unnecessary wakeups during deep sleep.
  • Improved S2Idle behavior to avoid excessive wakeups and better battery efficiency.
  • Disabled debug tracing and IRQ monitoring during suspend to reduce power drain.
  • Reduced freeze_timeout to 1s to avoid long screen-off delays.
  • Avoided CPU wake-ups caused by DMA latency changes (CDSP tuned to 67μs).
  • Dropped unused debug logic in cpuidle and PM subsystems.
  • Enabled polling idle state with time limit for efficiency during race conditions.
  • Multiple improvements to PM QoS: smarter latency control and IRQ balancing.
  • CPU idle state tracking improved for late-stage idleness to prevent unnecessary IPIs.

🎛️ Scheduler & UClamp Tuning

  • Introduced CASS (Capacity Aware Superset Scheduler) to improve CPU selection based on task needs.
  • Refined UClamp support: system and task-level utilization limits are more accurate and predictable.
  • SchedTune Assist v3 added for advanced tuning of foreground/background processes.
  • Numerous scheduler upstream/backport patches to reduce latency, boost interactivity, and avoid race conditions.
  • Optional SchedBoost tuning based on cluster priority and CPU utilization.
  • Enabled uClamp system-wide, with default boost for RT tasks.
  • UClamp aware frequency selection and boost decisions.
  • Extended sched_setattr() to fully support task-specific clamp values.
  • Better propagation of clamp limits across parent/child tasks and cgroups.
  • Clamps now correctly enforced and dynamically updated on wakeups.
  • Enabled schedutil tuning for more efficient frequency scaling.
  • Reworked loadavg and wakeup logic to prevent data races and improve responsiveness.

📱 Device & Hardware Support

  • Specific tuning for Atoll platform: watchdog disabled on suspend, fixed IRQ issues, and adjusted GPU DDR speed.
  • Adreno 6xx-only driver compilation: removed legacy code for faster builds.
  • Qualcomm devfreq boosting added for better dynamic GPU/CPU scaling.
  • WireGuard support enabled.
  • Fixed regressions in binder and UFS drivers improving stability and compatibility.
  • GPU idle timeout adjusted to 64ms for better balance between power and performance.
  • GPU coresight and snapshot logging disabled to reduce logging overhead.
  • CPU frequency tables now overrideable via Device Tree (DT) for better tuning.
  • Fixed frequency inconsistencies and enabled higher DDR frequency for GPU on Atoll.
  • Disabled Spectre v2 mitigations deemed redundant for this platform.
  • Enabled XFRM_MIGRATE for IPsec address handoffs (useful for some VPNs).
  • Disabled watchdogs and unused memdump regions for faster suspend/resume.

🔐 Debugging & Security Cleanup

  • Removed Samsung and Qualcomm debug logs to reduce kernel size and log spam.
  • Disabled unnecessary kernel debug features (e.g., DEBUG_FS, self-hosted debug, HW tracing).
  • Addressed multiple security issues: UAFs, null dereferences, memory leaks, and race conditions.
  • SELinux tweaks: now allows init to execute ksud under nosuid contexts.
  • Kernel logs cleaned: removed unnecessary pr_debug() and debug macros.
  • DebugFS, HW tracing, RKP, and SM_DEBUGCC disabled for production-grade security.
  • Kernel now warns when IRQ affinity notifiers are overwritten — helps detect conflicts early.
  • KernelSU scope-minimized hooks added, reducing the risk of exposure while rooted.

💾 File System & Storage Optimizations

  • Massive update to EROFS with:
    • Per-CPU buffer decompression.
    • Big physical cluster support (multipage, configurable).
    • Workqueue-based decompression for smoother multitasking.
    • Full move from staging to mainline fs/erofs.
    • Dozens of bug fixes, including corruption detection and recovery paths.
  • Tweaked ZRAM to use LZ4 with 64KB dictionary for performance.
  • Enabled LZ4 v1.9.4 with ARM64 SIMD acceleration.
  • ext4, F2FS, and nilfs2 all updated for stability, better memory usage, and metadata accuracy.
  • Enabled on-disk compression settings and sanity checks.
  • Improved inode tracking and atime updates to match upstream expectations.

🤖 Android-Specific Enhancements
