…ack) Brings in upstream sgl-project/sglang main commits since 096ad02 (merge base, Laguna-XS.2 model support). Total: 28 upstream commits composed. Custom-stack files preserved intact (entirely-ours, byte-identical to origin/main): - Blackwell CuTe kernel suite (warp_decode_cute, g1_attention_cute, gated_norm_cute, layersplit_cute, fused_store_index_cache) - TurboQuant 2.5-bit dense KV cache path - HIGGS 2-bit dense KV cache path (with split-K decode) - NVFP4 IndexCache dispatcher (active gate) - quantization_config_dispatch (HF-config-driven runtime routing) - All custom server-args flags and runtime methods preserved Verification: - 200+ merged Python files compile cleanly - Dispatcher symbol presence verified - HIGGS pool / TurboQuant pool classes present at expected lines - compressed_tensors_w4a4_nvfp4_moe imports clean - All custom server-args flags present (enable_higgs_dense_2bit_kv_cache, enable_turboquant_dense_kv_cache, turboquant_dense_kv_preset, indexer_quantization_declared, higgs_mla_decode_num_splits, etc.) Manual-merged shared files (auto-merge gave broken/mixed output; cleaned up post-merge): - python/sglang/srt/disaggregation/mooncake/conn.py: upstream's PR#24932 refactored maybe_send_extra into a state-types-loop. Replayed our LayerSplit NSA state-index-length-mismatch check inside the SWA/NSA branch of the new loop body. - sgl-kernel/python/sgl_kernel/__init__.py: upstream's PR#23449 (Apple Silicon Metal kernel) wrapped the entire module body in `if darwin/arm64: from sgl_kernel.metal import * else: ...`. The auto-merge duplicated the file body; rewrote cleanly with upstream's structure and re-injected our `g1_gate_forward`, `warp_decode_cute_moe_forward`, and `warp_decode_cute_moe_packed_forward` imports plus `g1_gate_forward` in _DEBUG_EXPORT_NAMES. - python/sglang/srt/managers/scheduler_output_processor_mixin.py: line 628 still referenced `result.num_accepted_drafts` (renamed by PR sgl-project#25038 to `num_correct_drafts`). Renamed in place. - python/sglang/srt/observability/scheduler_metrics_mixin.py: a block around the spec-decode logging path had mixed old/new names from auto-merge (lines 553/557/560). Renamed `spec_num_accepted_tokens` -> `spec_num_accept_tokens` and local `num_accepted_drafts` -> `num_correct_drafts` to match the rest of the file. - test/test_smc_info.py: stub Req mock used the old field names `spec_accepted_drafts` and `update_spec_acceptance_histogram`. Renamed to `spec_num_correct_drafts` and `update_spec_correct_drafts_histogram` per PR sgl-project#24081. Auto-merge cleanly integrated upstream changes to: - server_args.py (new fields: prefill_only_disable_kv_cache, weight_loader_drop_cache_after_load, prefill_delayer_queue_min_ratio, prefill_delayer_max_delay_ms, speculative_draft_window_size, etc.) - mem_cache/memory_pool.py (new NoOpMHATokenToKVPool) - model_executor/model_runner_kv_cache_mixin.py (NoOpMHATokenToKVPool pool factory + _validate_prefill_only_disable_kv_cache_pool_family) - layers/attention/nsa_backend.py (spec rename num_accepted_drafts -> num_correct_drafts; num_accepted_tokens -> num_accept_tokens) - layers/attention/nsa/nsa_indexer.py (new _apply_q_scale_and_softmax_scale compile method; torch.mm replaces deep_gemm wrapper) - 28+ disaggregation/spec/runner files with mostly clean upstream-side-only integration.
