Interrupt Topology Contracts: Review Checklist

Review Checklist for Interrupt Topology Contracts.

Review checklist

Review Checklist for Interrupt Topology Contracts focuses on interrupt latency tail, missed-interrupt incidents. The goal is to map symptoms to boundary contracts, owner actions, and regression-proof closure.

Baseline manifest and revision are explicit.
Boundary contracts for this topic are current and approved.
Ownership map covers all open issues.
Focused and full regression evidence both exist.
Residual risks are either closed or bounded via waiver policy.
Owners signed: firmware owner, platform architect, RTL owner.

OWNERSHIP MAP — Interrupt Topology Contracts

artifact             owner
-----------------    -----------------
primary owner     firmware owner
co-owner          platform architect
review owner      RTL owner

No top-level issue should remain ownerless beyond one review cycle.

SoC deep dive

Address, interrupt, and IO contracts are where hardware/software alignment is won or lost.

Reports and artifacts

address decode audit
interrupt latency report
IO bring-up checklist
boot contract review

Mini case study

A map alias issue caused sporadic peripheral misconfiguration despite clean block-level tests.

Debug branches

Freeze address map baseline
Audit reset defaults
Validate firmware assumptions

Senior review question

Ask: what baseline, owner, and artifact prove this topic is truly closed?

Key takeaways

State baseline manifest and owner with every closure metric.
Run cross-domain regression after every top-level fix.

Common pitfalls

Comparing results across different manifests.
Unowned issues slipping through review cycles.
Waiving risks without expiry and validation plan.

Principal SoC review addendum

Interrupt architecture defines aggregation, priority, routing, and affinity policies that software relies on for deterministic response.

Metric: interrupt latency tail, missed-interrupt incidents
