STATUS_GRAPHICS_NO_AVAILABLE_IMPORTANCE_ORDINALS
The topology has no free importance ordinal left
Path importance ordinals provide an ordering among VidPN present paths. This status means the topology already uses every ordinal value that can be assigned, so another path cannot receive a valid unique ordinal.
It usually appears when topology augmentation creates more paths than the interface can order, or when duplicate/corrupt ordinal handling consumes the available range. The failure is about path ordering metadata, not raw GPU memory or monitor bandwidth.
What to check
- Count paths and list their ordinals before adding the new path.
- Look for duplicate paths that unnecessarily consume ordinals.
- If augmentation is optional, reduce the candidate path set before assigning ordinals.
