Daily Work Summary: 2026-03-21

* Crash Analysis: Evaluated hard lockup before REISUB. Traced to iGPU/VF reset event at 14:12. Logs showed high-frequency noise from Gemini Voice prior to hang. * Stability Improvement: Disabled Gemini Voice persistently to eliminate API-loop overhead. * Performance Service Fix: Refactored max-performance.service into a robust standalone script at /usr/local/bin/max-performance.sh, resolving fatal startup errors. * Btrfs Optimization: Applied high-performance mount options (commit=60,compress=zstd:1,noatime) to all subvolumes on the NVMe SSD. Removed redundant autodefrag. * VM Optimization: Updated recovered_vm.xml with:

Static Hugepages for reduced memory latency.
IOThreads assigned to VirtIO-SCSI, pinned to host Core 4.
Emulator Pinning to Cores 4-5 to prevent interference with VM P-cores (0-3).

* HUD Security: Implemented “Bright Red” VF Watcher in Conky. HUD now blinks and alerts if the iGPU VF is hijacked or detached from VFIO.
