Pull Request Overview
This PR modifies the QNN execution provider to support Gemm operations with 2D bias matrices when targeting HTP (Hardware Transform Pipeline). Previously, these operations would fall back to CPU execution.
- Updates Gemm operator support to handle 2D bias matrices by decomposing them into FullyConnected + ElementwiseAdd operations
- Modifies validation logic to allow 2D bias with shape [N, M] for non-quantized inputs
- Updates test cases to verify that Gemm with 2D bias is now assigned to QNN EP instead of falling back to CPU
