test_xpu_profiler_use_cases.py adds four single-process tests on XPU: basic eager GEMM profiling, torch.compile + Inductor profiling (gated on has_triton(), verified via the Dynamo Torch-Compiled Region annotation), XPUGraph capture/replay with acc_events=True, and the scope profiler experimental_config API surface. test_xpu_profiler_distributed.py adds an XCCL all_reduce profiling test using MultiProcessTestCase, so it runs under pytest without an external torchrun launcher. All kernel assertions match GEMM kernel names case-insensitively to cover both gemm_kernel (PT 2.12+) and xe4_gemm (older releases).
