Previously, I was iterating through all kdePackages, which contained not only apps, but also libraries and added it all to systemPackages, which inflated systemPakcages. Turns out there is curated set which contains apps, let's make use of it.
EasyEffects DSP plugins (rnnoise, deepfilternet, crystalizer) drop audio
when the system is under load. Layered workaround with per-optimization
toggles for bisecting impact:
- cgroup-based CPU partitioning: dedicated audio.slice with AllowedCPUs
pinning, restricted app/session/background slices for everything else
- rlimits so PipeWire's module-rt sets SCHED_FIFO 88 directly instead of
going through RTKit's priority-10 ceiling
- persistent watcher that re-applies performance governor on audio cores
(gamemoded/PPD keep resetting it)
- ananicy rule pinning easyeffects to nice -12 for non-RT DSP threads
- znver4-tuned rebuilds of easyeffects and its DSP deps
Master switch + per-feature toggles via lumpiasty.audioRt.*; all enabled
by default on acer host. None of this fully eliminates dropouts on this
thermally constrained laptop but each layer is independently testable.
