GPU-TOPO-01: GPU-NVSwitch topology is consistent across signed reports¶
| Property | Value |
|---|---|
| Severity | medium |
| Platform | Hardware fleets (collector) |
| Lifecycle stage | hardware |
| Evaluated from | Evidence sent to the service (collector bundles or registry scans), not from a cloud API scan. |
What it checks¶
It passes when:
- … GPU and … NVSwitch reports verify to NVIDIA's device CA for this challenge, every GPU is in protected-PCIe mode and the GPU/NVSwitch PDIs agree in both directions.
How to fix¶
- Treat this protected-PCIe domain as untrusted: a GPU or NVSwitch report does not verify, or the signed topology does not match the devices that attested.
After the fix, scan again: the check should report PASS.
