ASB V13.6 - Changelog

Standby Battery (VM)

  • vm.dirty_expire_centisecs: 4000 -> 6000
  • vm.dirty_writeback_centisecs: 3000 -> 5000
  • vm.compaction_proactiveness: 1 -> 0
  • vm.stat_interval: 10 -> 15

Why:

  • More time for cache coalescing means fewer storage controller wakeups during idle/background.
  • Disables proactive compaction work that can create unnecessary background CPU load on high-RAM devices.

Note:

  • Longer dirty writeback windows slightly increase the amount of unsynced data during sudden power loss.

Network Stability

  • net.ipv4.tcp_slow_start_after_idle: 0 -> 1

Why:

  • More predictable behavior after short pauses on mobile networks (better re-probing of available bandwidth).

GPU Idle Tuning (Restored)

  • Added GPU idle tuning back into apply_idle():
    • sleep_disabled=0 (allows deep sleep)
    • min_pwrlevel=6 (prefers lowest power state in idle, if supported)
    • bus_split=1 (power-gates unused bus segments, if supported)
  • apply_idle is now included in the reapply loop to survive system resets.

Wild Kernel Safety Fix

  • Fixed a bug where cpu_groups were skipped on Wild at boot, but still re-applied later by the background reapply loop.
  • cpu_groups are now consistently skipped on Wild kernel in both boot and tail loop.

Result:

  • Less risk of constant boosting / unnecessary heat on Wild kernel
  • Better standby behavior without reducing real-world performance

Summary

ASB V13.6 focuses on:

  • Better idle/standby battery through VM writeback + reduced background kernel work
  • More stable mobile networking.
  • Restored GPU idle power saving with safe re-application
  • Correct Wild-kernel handling to avoid reapply regressions

Recommended for daily use.
