Page Fault Handling, Trap Flow, and Recovery Paths: Design Space
Design Space for Page Fault Handling, Trap Flow, and Recovery Paths.
Design space
Design Space for Page Fault Handling, Trap Flow, and Recovery Paths is anchored on Fault service latency (median/P99), restart success rate, and throughput impact during demand paging and copy-on-write stress.. Convert observations into mechanism-backed decisions with explicit ownership.
Trade latency and throughput against power and area.
Prefer architecture options with clear software contract impact.
Quantify extension-profile cost before enabling by default.
Keep bring-up and validation ownership explicit.
