+# MiniMax-M3 MXFP8 MI300X (gfx942) single-node vLLM recipe with EAGLE3
+# speculative decoding — the spec-decoding=mtp variant of
+# minimaxm3_fp8_mi300x.sh. Adds the Inferact/MiniMax-M3-EAGLE3 draft head via
+# --speculative-config with 3 speculative tokens. Everything else mirrors the
+# non-MTP MI300X recipe: mandatory --block-size 128, --language-model-only for
+# the text-only benchmark, --attention-backend TRITON_ATTN, --enforce-eager,
+# and --no-enable-prefix-caching. The default BF16 KV cache is retained (unlike
+# the MI355X recipe's FP8 KV cache): gfx942 has no calibrated q/prob scales for
+# ROCm FP8 attention and vLLM's fallback scale of 1.0 corrupts accuracy.
+#
+# Unlike the CUDA recipes, the drafter needs no attention_backend override:
+# the FlashInfer "page size 128 requires GQA/MQA" limitation that forced
+# FLASH_ATTN for the EAGLE3 MHA head on Blackwell is FlashInfer/CUDA-specific.
+# Here the whole server runs on TRITON_ATTN (set globally below), which serves
+# the MHA draft fine.
+#
+# [AI generated draft test] The shipped vllm/vllm-openai-rocm:minimax-m3 image
+# does NOT implement SupportsEagle3 on the AMD MiniMax-M3 model, so EAGLE3
+# engine init fails with "Model does not support EAGLE3 interface but
+# aux_hidden_state_outputs was requested". This recipe applies that fix
+# (functionstackx/vllm#1 — ported from nvidia/model.py, upstreamed as
+# vllm-project/vllm#45546) in-place to the installed vllm before serving, so we
+# can validate EAGLE3 on real MI300X hardware ahead of an image rebuild. The
+# same patch is validated green on MI355X. It is idempotent and fails the job
+# loudly if the installed amd/model.py has drifted from the expected base.
