STATUS_GRAPHICS_CANCEL_VIDPN_TOPOLOGY_AUGMENTATION
The miniport asked the VidPN manager to stop augmentation
Topology augmentation is the process of extending a VidPN topology with additional paths or compatible modes. This status means the display miniport driver requested that the augmentation step be cancelled for the specified source.
Treat it as a controlled driver response during negotiation, not as an unexplained kernel failure. It can indicate that the driver determined no valid augmentation exists under current source, target, mode, or hardware constraints and chose to stop that branch.
What to check
- Log the source ID and current candidate topology when the miniport returns this status.
- Compare with earlier cofunctional mode enumeration; lack of candidates often explains the cancellation.
- Do not continue committing a topology branch after the miniport explicitly cancels its augmentation.
