Root Cause

This test was disabled because it is failing on main branch (recent examples).

PR fix notes

PR #180277: [ROCm][inductor][UT] Preserve combo kernel HIP compile options

Description (problem / solution / changelog)

Fixes #180011 Fixes #180012 Fixes #180013 Fixes #180014 Fixes #180015 Fixes #180016 Fixes #180021 Fixes #179952 Fixes #180022 Fixes #180025 Fixes #180027 Fixes #180028 Fixes #180029 Fixes #180549

This appears to have regressed in #177715, where combo-kernel autotuning started materializing alternate per-subkernel configs. This change keeps Triton HIP compile options such as waves_per_eu, matrix_instr_nonkdim, and kpack kernel-wide when combo kernels rewrite per-subkernel configs, avoiding invalid names like waves_per_eu_0. It also routes both baseline combo configs and sequential combo autotune trials through the same kwarg rewrite helper and adds a regression test covering combo-kernel kwarg rewriting for AMD special config args.

PR #180319: [ROCm] Handle profiler trace format differences in combo kernel tests

Description (problem / solution / changelog)

Fixes #180017. Fixes #180018. Fixes #180019.

Three combo kernel tests access event["args"]["grid"] from profiler chrome traces. The grid key structure differs between CUPTI and ROCTracer trace formats, so this throws KeyError on ROCm.

Use .get() and only assert on grid values when present. All other validation (numerical correctness, kernel counts, codegen) still runs. No change to CUDA path where grid is always present there so assertions execute as before.

extent analysis

TL;DR

The test failure on the main branch may be resolved by re-enabling and re-running the disabled test test_combo_kernels.py to identify and address the underlying issue.

Guidance

  • Investigate the recent examples of test failures on torch-ci.com to understand the nature of the failure and potential causes.
  • Re-enable the disabled test test_combo_kernels.py and re-run it to gather more information about the failure and to identify potential fixes.
  • Collaborate with the listed maintainers and contributors to discuss potential solutions and to assign tasks for resolving the issue.

Notes

The provided information lacks specific technical details about the test failure, making it challenging to provide a more detailed solution.

Recommendation

Apply workaround: Re-enable and re-run the disabled test to gather more information and identify potential fixes, as the root cause of the issue is not clearly stated.
