The changes are consistent across all modified files, including the removal of the test file, updates to the quantization registry, and removal from the ROCm platform's supported quantization list. The deprecation notice for PTPC FP8 was previously released in 0.14, making this removal a logical next step. No issues were found.

Missing closing quote breaks shell script syntax

High Severity

Removing the --ignore=kernels/moe/test_triton_moe_ptpc_fp8.py" line also removed the closing quote for the string literal. Line 134 now ends with a backslash \ (line continuation) without a closing quote, causing fi on line 135 to become part of the string instead of terminating the if block. This will cause a bash syntax error and break the AMD hardware CI pipeline.

@robertgshaw2-redhat does the current fp8 quantization works on ROCm as well? Is the NVIDIA's fp8 is PTPC quantization?
