From 751e3e0868806c1f1f966e3b0820f7bdf6083df5 Mon Sep 17 00:00:00 2001 From: Kazeia Team Date: Tue, 14 Apr 2026 22:44:09 +0200 Subject: [PATCH] =?UTF-8?q?memory:=20periodic=20sweep=20+=20expand=20kill?= =?UTF-8?q?=20list=20(photos,=20calendar,=20contacts,=20vending,=20tachyon?= =?UTF-8?q?=E2=80=A6)?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit First sweep reclaimed 1.6 GB as advertised but ColorOS respawned most of the killed apps within 1–3 minutes — observed quicksearchbox coming back at 210 MB, photos/calendar spawning fresh at 150+ MB each. Two changes: 1. Expanded KILL_TARGETS with the packages that showed up in the respawn wave (Google Photos, Calendar, Contacts, Play Store, rkpdapp, Tachyon/Meet, permissioncontroller, notificationmanager, safecenter, securitypermission, sau, acore). These are user-facing but not needed while Kazeia is the active task; they re-spawn on demand if the user switches away. 2. New startPeriodicOptimizer() runs freeRamForModels every 60 s for the lifetime of KazeiaService so re-spawned apps get trimmed again without a service restart. Tied to serviceScope so it stops cleanly on destroy. Net effect observed: avail RAM stays ~1.2–1.5 GB higher than without the sweep. Models still land in ZRAM once the LLM/TTS/STT finish loading (Kazeia itself is ~5 GB across them), but page-fault thrashing during inference is noticeably reduced.
