Pinned Stack & Model Versions

Offline Boundary (100% Offline Unified Multi-Backend OpenAI Endpoint (`127.0.0.1:13305/api/v1`))
Once ROCm GGUF and FastFlowLM NPU checkpoints are pulled via `lemonade-server pull`, both NPU (`/dev/accel/accel0`) and iGPU (`/dev/kfd`) run 100% offline with zero external telemetry.
Known Operational Limits & Failure Modes
- **`flm validate` Fails Immediately Without `memlock unlimited`:** The Linux `amdxdna` / XRT runtime pins NPU buffer objects (BOs) directly in non-pageable host memory. Ubuntu’s default `ulimit -l` (`65536 KB` or `8192 KB`) causes `FastFlowLM` NPU model loading to abort with `DRM_IOCTL_AMDXDNA_CREATE_BO failed / ENOMEM`. Set `* soft memlock unlimited` and `* hard memlock unlimited` in `/etc/security/limits.conf` (plus `LimitMEMLOCK=infinity` if running `lemonade-server` as a `systemd` service).
- **Shared `256 GB/s` LPDDR5X-8000 Bus Contention (~11–14% Simultaneous Dip):** While XDNA 2 NPU compute is physically separate from the 40-CU Radeon 8060S GPU, **both engines read weights from the same 256-bit LPDDR5X-8000 memory controller (`256 GB/s`)**. When an `flm:npu` 8B stream and a `ROCm 7.2` 35B/109B stream decode at the exact same millisecond, GPU tok/s dips by `~11–14%`—still vastly superior to the `8–25 second` model-swap freeze caused by sharing a single GPU server!
- **`Llama-4-Scout-17B-16E` (`109B`) Active-Parameter Speed Ceiling (`~15–20 tok/s`):** Even though both `Qwen3.6-35B-A3B` and `Llama-4-Scout` fit inside the 108GB UMA pool, `Qwen3.6-35B-A3B` activates only **`3.0B` params/token (`~79 tok/s` at Q4 / `~56 tok/s` at Q8_0)** whereas `Llama-4-Scout` activates **`17B` params/token (`~15.4 tok/s` at Q4_K_M / `~19.6 tok/s` at Q3_K_XL)** due to `256 GB/s` memory bandwidth physics.
DEPLOYMENT CHECKLIST // 配置落地核验步骤
3-Step Verification Checklist After Deploying setup-lemonade-npu-igpu-dual-engine.sh
- Verified `/dev/accel/accel0` exists, `ulimit -l` outputs `unlimited`, and `flm validate` passes kernel, `amdxdna`, and NPU firmware (`>= 1.1.0.0`) checks.
- Set `amdttm.pages_limit=28311552` (`108 GB` GTT ceiling on 128GB host) while keeping `~20 GB` reserved for Ubuntu kernel, ZFS/page cache, and IDE containers.
- Routed IDE autocomplete / lightweight tasks to `flm:npu` (`Llama-3.2-3B` / `Qwen3-8B`) and main coding agent sessions to `ROCm 7.2` (`Qwen3.6-35B-A3B` or `Llama-4-Scout`) via `lemonade-server`.
