If your “FPState VSO” means something else (e.g., a specific library, a kernel feature, or a different product), please clarify and I will adapt the feature spec accordingly.
| Component | Requirement | |-----------|--------------| | Target | x86/x64 with AVX/AVX2 support; ARM NEON optional | | Protocol | Extend Debug Adapter Protocol (DAP) with FPState request | | UI | Tree view (registers + vector lanes) + optional hex/float toggle | | Performance | Snapshot < 5 ms overhead, diffing lazy | | Remote | Works over VS Online tunnel / VS Code remote | fpstate vso
