Verification: official_abstract; confidence=high.
Question: Can Linux memory-prefetch policies be customized safely without maintaining kernel forks?
Context: Kernel-resident prefetch policies are hard to prototype, deploy, and tailor per workload.
Method: FetchBPF exposes memory-prefetch hooks and policy state through eBPF, enabling verified user-defined policies in a stock-kernel framework.
Evaluation: workloads=prefetch policies reproduced from prior work; baselines=equivalent native-kernel policies; metrics=runtime overhead; prefetch effectiveness; results=negligible framework overhead
Interpretation: A constrained programmable interface can preserve performance while shortening policy iteration and deployment.
Reusable lesson: Move policy into a safe extension layer while keeping mechanisms in the kernel.
Applicability: Linux VM prefetch experimentation and workload-specific deployment.
Limits: The demonstrated domain is prefetching; eBPF verifier and helper interfaces bound policy expressiveness.
