EVONIX Kernel V4.5

For POCO X7 Pro / Redmi Turbo 4 (rodin). Available for HyperOS and ColorOS, with Normal and KernelSU Next + SUSFS editions.

CPU scheduling and performance

  • Added latency-sensitive wakeup handling and shorter scheduling slices for tasks marked by the ROM.
  • Added PREEMPT_SHORT scheduling while retaining Android and MediaTek scheduling decisions.
  • Reduced repeated EEVDF eligibility calculations.
  • Fixed task-group runnable accounting overflow.
  • Corrected CPU-group selection for queued workloads.
  • Fixed utilization-clamp values carrying over between EAS CPU candidates.
  • Removed duplicate utilization updates during CPU and idle-state selection.
  • Skipped EAS domains without an allowed CPU candidate.
  • Avoided unused fallback calculations when MediaTek supplies CPU placement.
  • Reduced unnecessary frequency and CPU-capacity scans.
  • Improved guarded migration of queued workloads to suitable idle, higher-capacity CPUs.
  • Prevented failed misfit migrations from delaying unrelated load balancing.
  • Removed unnecessary destination searches and load-balancer updates.
  • Preserved vendor-requested NOHZ balancing work.
  • Added DVFS notifications when active cgroup performance clamps change.
  • Fixed CPUFreq policy initialization and reduced repeated frequency-table lookups.
  • Corrected schedutil rate-limit conversion overflow.

Power management and idle

  • Added power-efficient handling for selected asynchronous power-management work.
  • Reduced redundant deferred DMA-buffer worker notifications.
  • Avoided unused runtime-idle callback lookups.
  • Corrected normal-task timer-slack inheritance from real-time parents.
  • Fixed idle power-domain allocation cleanup and clocksource registration cleanup.
  • Corrected the userspace wakelock-limit boundary and tick-broadcast replacement race.
  • Reduced unnecessary memory clearing in OEM charging-status reads.

Memory and multitasking

  • Made proactive MGLRU reclaim interruptible during suspend.
  • Made interrupted memory-reclaim requests restartable.
  • Added Tasks-RCU progress reporting during reclaim, page migration and cgroup writeback.
  • Stopped obsolete memory-cgroup reclaim after newer limit updates.
  • Fixed locked-memory accounting and allocator zeroing.
  • Fixed shrinker callback handling.
  • Corrected swap readahead after its configured ceiling is lowered.
  • Rejected unsafe direct swap files on filesystem-encrypted storage.
  • Fixed repeated DAMON region aging, merge-threshold overflow and stale access-result reuse.

Storage and filesystems

  • Fixed ext4 orphan-buffer leaks and stale writeback tags.
  • Corrected ext4 direct-I/O to buffered-I/O fallback handling.
  • Fixed F2FS move-range validation and writeback error reporting.
  • Fixed block-cgroup creation cleanup, statistics traversal and dying-group handling.
  • Corrected block-device timeout cleanup and queue teardown.
  • Included offline CPUs' pending latency samples in block, Kyber and I/O-cost accounting.

Networking and kernel fixes

  • Fixed TCP retransmission lifetime, urgent-data corruption and outdated-ACK handling.
  • Fixed UDP tunnel-segmentation use-after-free.
  • Corrected IPv6 checksum bounds, extension-header parsing and segment-routing validation.
  • Fixed ARP interface-name termination, XPS traffic-class validation and IPv4 route cleanup.
  • Fixed POSIX CPU-timer lifetime races and PID-reference leaks.
  • Corrected timer-migration state, workqueue flush checks and watchdog overflow handling.
  • Fixed ARM64 per-CPU write casting and bitmask generation.

ColorOS

  • Integrated native MT6899 OPlus SchedAssist with MediaTek scheduler hooks.
  • Isolated OPlus scheduler storage from Xiaomi scheduler data.
  • Added the native waker-identification scheduler bridge.
  • Integrated FrameBoost with corrected MT6899 cluster ordering and CPUFreq-aware initialization.
  • Added OPlus CPUFreq health support and fixed OCH frequency-table lookup.
  • Integrated MIDAS v2.
  • Added OPlus process-reclaim, kswapd and proactive-compaction helpers.
  • Added HealthInfo Lite CPU-loading support.
  • Added OPlus project identification, rodin fallback and device/memory diagnostics.
  • Added Phoenix observation support without enabling its recovery watchdog.
  • Brought the shared V4.5 changes to both ColorOS editions.

KernelSU Next editions

  • Updated KernelSU Next to v3.4.1.
  • Corrected SUSFS kernel-stat compatibility with userspace.
  • Simplified SUSFS filesystem-stat handling using the existing VFS helper.
