Resource management on embedded gaming devices
summary
Meta builds Orchestrator, a Rust policy framework that centralizes cgroup v2 control, runs BPF collectors into BPF ring buffers, and enforces per-process budgets with throttles and SIGABORTs. It migrates controllers into a unified hierarchy, isolates kthreads, and ships telemetry and a budget policy in dogfooding where violations trigger telemetry, throttling, or kills. A planned transparent memory offloading policy dynamically reclaims working sets by monitoring per-process PSI and adjusting memory.high.
