llama.cpp 修復 NextN 提取引發的排程器重分配報錯

llama.cpp releases10/6 14:10版本更新地端推論開源

llama.cpp 發布 b11440,修復投機 MTP 解碼中 NextN 提取標誌變化導致的排程器預留失效報錯。啟用 MTP 後,NextN 提取在目標與草稿上下文的排程器已預留之後才開啟;未掩碼提取時主幹圖保留最後一層的全部 token 而非裁剪到輸出行,首次解碼按該批次形狀重分配,下一批更寬的批次就會觸發 GGML_SCHED_DEBUG_REALLOC。修復方式是在標誌變化時作廢預留,讓下一次計算按新圖形狀重新預留,並隨各平台預編譯包發布。

llama : re-reserve the sched when the nextn extraction flags change ( #30020 ) The speculative MTP init enables NextN extraction on the target and draft contexts after both were created and their schedulers reserved. With unmasked extraction the trunk graph keeps every token through the last layer instead of cropping to the output rows, so the first decode reallocates to that batch's shape and the next, wider batch trips GGML_SCHED_DEBUG_REALLOC. Invalidate the reserve when the flags change so the next compute re-reserves with the new graph shape.

llama.cpp 修復 k-pool 模型圖重分配導致的解碼中止

llama.cpp 發布 b11412,修復 k-pool 模型(qwen4exp、glm5-next)解碼時意外重新預留計算圖並中止的問題。原因是兩模型按 cache_safe、n_tokens 等 reserve 無法預知的狀態分支,解碼圖與預留圖節點數不一致(如 7564 對 7762),解碼時被迫按當前狀態重預留、丟掉最壞情況尺寸,在 GGML_SCHED_DEBUG_REALLOC=1 下直接 abort。
