cudagraph tests blocked by feature gap

[daisyden]

Summary

A set of cudagraph-related tests across dynamo, inductor, and foreach test suites are blocked on XPU because the xpugraph feature is not yet implemented or equivalent to CUDA graph support. This is a feature gap tracking issue listing all affected test cases that need xpugraph to be enabled before they can pass.

Type

• Category: feature-gap
• Platform: xpu
• Related Components: xpugraph, test/dynamo/test_backends.py, test/dynamo/test_cudagraphs.py, test/dynamo/test_cudagraphs_expandable_segments.py, test/dynamo/test_structured_trace.py, test/test_foreach.py, test/inductor/test_cuda_repro.py

Objective

Implement or enable xpugraph support to unblock the listed cudagraph test cases on XPU.

Context

Versions: main. Tests are blocked by xpugraph feature gap, not by a runtime error.

Root Cause Analysis

XPU does not have an equivalent implementation of CUDA graph support (xpugraph). The listed tests across dynamo, inductor, and foreach test suites require cudagraph/xpugraph functionality that has not yet been implemented for XPU. This is a feature gap, not a runtime bug.

Proposed Fix Strategy

Implement xpugraph support for XPU, analogous to CUDA graph support. This would require significant new feature development in torch-xpu-ops and/or pytorch for XPU graph capture/replay infrastructure.

**Verdict:** NEEDS_HUMAN **Reason:** Feature gap issue — xpugraph is not yet implemented; requires substantial new feature development, not a single fixable bug.

Root Cause: XPU does not have an equivalent implementation of CUDA graph support (xpugraph). The listed tests across dynamo, inductor, and foreach test suites require cudagraph/xpugraph functionality that has not yet been implemented for XPU. This is a feature gap, not a runtime bug.

Fix Strategy: Implement xpugraph support for XPU, analogous to CUDA graph support. This would require significant new feature development in torch-xpu-ops and/or pytorch for XPU graph capture/replay infrastructure.
