Description
This PR adds new C API for querying hardware device and execution provider (EP) compatibility/incompatibility reasons. The API allows applications to determine why a specific EP may not be compatible with a given hardware device before attempting to use it. The EP implementor decides how device compatibility is defined for their stack and communicates this via the possible states in the OrtDeviceEpIncompatibilityDetails struct.
New API Functions
New Types
Testing
. Tests verify both compatible (CPU device with CPU-supporting EP) and incompatible (GPU device with CPU-only EP) scenarios
Motivation and Context
Applications using ONNX Runtime need a way to understand why an execution provider cannot run on a particular hardware device. This is especially important for:
Previously, there was no standardized way to query this information. EPs would simply fail at session creation/model load/inference time without providing actionable feedback.
