+# tts-server containerizzato (Qwen3-TTS, backend Vulkan)
+
+Containerizza il server TTS (qwentts.cpp) con accelerazione GPU **Vulkan**,
+portabile su qualsiasi host con GPU AMD/Intel (Mesa RADV) o NVIDIA (ICD Vulkan).
+
+## Architettura
+
+- **Multi-stage build**: builder con Vulkan SDK (glslc da LunarG) → runtime
+  minimale con `mesa-vulkan-drivers` (RADV userspace).
+- **Nessun driver kernel nel container**: l'host possiede l'hardware; il
+  container monta solo `/dev/dri/renderD128` (node render, least-privilege).
+- **`GGML_NATIVE=OFF`**: binario portabile tra CPU diverse.
+- **Voci clonate** (`.spk`/`.rvq`) registrate all'avvio da `register_voices.py`
+  (scansione ricorsiva di `/voices`; ref_text dal `.txt` omonimo o
+  `*_batch_ref.txt`).
+
+## Requisiti host
+
+- Docker Engine + Docker Compose v2
+- GPU con driver Vulkan funzionante: verificare con `vulkaninfo --summary`
+- Node render: `ls -l /dev/dri/renderD128` (su Debian/Ubuntu serve il gruppo
+  `render`; su Fedora è world-writable)
+
+## Build & avvio
+
+```bash
+cd docker/tts-server
+export RENDER_GID=$(getent group render | cut -d: -f3)   # GID gruppo render
+docker compose up -d --build
+```
+
+Il compose monta `../models` e `../voices` (relativi al file compose, cioè la
+root del repo) e pubblica la porta **8881**.
+
+## Verifica
+
+```bash
+curl http://localhost:8881/health          # {"status":"ok"}
+curl http://localhost:8881/v1/audio/voices # elenco voci registrate
+```
+
+## Configurazione (variabili d'ambiente)
+
+| Variabile | Default | Descrizione |
+|---|---|---|
+| `MODEL_PATH` | `/models/qwen-talker-1.7b-base-Q8_0.gguf` | Modello talker |
+| `CODEC_PATH` | `/models/qwen-tokenizer-12hz-Q8_0.gguf` | Codec audio |
+| `TTS_LANG` | `auto` | Lingua (es. `Italian`) |
+| `MODEL_ALIAS` | — | Alias esposto da `/v1/models` |
+| `PORT` | `8881` | Porta di ascolto |
+| `VOICE_DIR` | `/voices` | Directory voci clonate |
+| `GGML_BACKEND` | `Vulkan0` | Backend ggml |
+| `NO_FA` / `CLAMP_FP16` / `MAX_BATCH` / ecc. | — | Flag avanzati tts-server |
+
+## Portabilità su altre macchine
+
+1. **AMD/Intel**: nessuna modifica — il container usa Mesa RADV dal
+   `mesa-vulkan-drivers` dell'immagine. Serve solo il node render.
+2. **NVIDIA**: aggiungere il runtime nvidia al servizio:
+   ```yaml
+   runtime: nvidia
+   environment:
+     NVIDIA_VISIBLE_DEVICES: all
+   ```
+   (richiede `nvidia-container-toolkit` sull'host) — oppure usare il target
+   `cuda` del Dockerfile principale del progetto.
+3. **Modelli**: montare la directory con i `.gguf` (talker + codec) come
+   `/models:ro`.
+4. **Voci**: montare la directory con `.spk`/`.rvq`/`.txt` come `/voices:ro`.
+
+## Troubleshooting
+
+1. Host: `vulkaninfo --summary` deve vedere la GPU.
+2. Container: `docker exec tts-server vulkaninfo --summary` (se `vulkan-tools`
+   installato) o controllare i log: `docker logs tts-server`.
+3. Se Vulkan non vede la GPU: verificare `--device /dev/dri/renderD128` e il
+   `group_add` (GID del gruppo `render` dell'host).
+4. Non bind-mountare librerie host (`/usr/lib`, ICD JSON): causa mismatch
+   loader/driver. L'immagine ha già RADV.
