3 people	a8a7716b53	build: split CUDA Docker images into cuda12 (12.9.x) / cuda13 (13.3.x), fix Blackwell Ultra arch gate (#23) ... The CMakeLists.txt >=12.8 CUDA-architecture branch claimed 121a-real (Blackwell Ultra) alongside 120a-real, but nvcc from CUDA 12.8.1 rejects compute_121 ("nvcc fatal: Unsupported gpu architecture 'compute_121'"). Confirmed against a real build: 12.8.1 compiles cleanly with 120a-real but not 121a-real; 12.9.2 compiles both. Split the >=12.8 branch into >=12.9 (full Blackwell + Ultra) and >=12.8 (Blackwell only, no Ultra). Since no single CUDA toolkit spans the full arch range -- 12.9.x is the newest 12.x that still emits Pascal (61-real) SASS, 13.x drops Pascal entirely but is otherwise more current -- the single :cuda image can no longer serve both audiences. Split it into two CI variants, :cuda12 (12.9.2, Pascal through Blackwell Ultra) and :cuda13 (13.3.1, Turing and newer). The Dockerfile's own --target cuda stage is unchanged; the CUDA_BUILD_IMAGE/CUDA_RUNTIME_IMAGE ARGs now default to 12.9.2 (was 12.4.1) and the CI matrix overrides them per variant. Both variants were build-tested against nvidia/cuda:12.8.1 and 12.9.2 locally and exercised with real end-to-end synthesis requests on an actual sm_61 card (GTX 1070 Max-Q) -- RTF ~0.4 on both, no kernel image / arch mismatch errors.

3 people	978fc08f5a	Add Dockerfile (cpu/cuda/vulkan), entrypoint, docs, and a GHCR build/release workflow (#15) ... * Add Dockerfile (cpu/cuda), entrypoint, docs, and a GHCR release workflow Multi-stage Dockerfile with cpu and cuda targets, built from the existing build scripts' cmake invocations. The CUDA target documents and applies the two docker-build-specific gotchas we hit running this in production: CMAKE_CUDA_ARCHITECTURES needs an explicit override for GPUs older than this project's own default arch list when building without GPU device access, and the CUDA driver stub library needs an explicit -L/-lcuda at link time since ggml's VMM pool allocator needs driver-API symbols that aren't present without a real driver. Also installs make/pkg-config/libopenblas-dev (CPU build) and libgomp1 (CUDA runtime), and copies the ggml shared libraries alongside the binaries with LD_LIBRARY_PATH set, since the binaries' baked-in RPATH points at the build-tree location that doesn't exist in the final stage. Adds a GitHub Actions workflow that builds both variants on every push to master and version tag, publishing to ghcr.io/serveurpersocom/qwentts.cpp, and validates the build (without pushing) on PRs that touch the Docker files. Verified end-to-end on a real GTX 1070 (Pascal): both cpu and cuda targets build clean, run, and produce valid synthesized WAV output through tts-server's HTTP API. * Dockerfile: add a vulkan build target (AMD/Intel GPUs) Uses the LunarG Vulkan SDK apt repo for glslc (ggml-vulkan's shader compiler), which Ubuntu 22.04's own repos don't package. Runtime image ships Mesa's Vulkan drivers; NVIDIA users should prefer :cuda instead, since NVIDIA's Vulkan ICD isn't bundled. * docker workflow: bump actions to latest majors (checkout v7, buildx v4, login v4, build-push v7) * Support Pascal (sm_61) in the default CUDA architecture list Adds 61-real to CMAKE_CUDA_ARCHITECTURES' default so Pascal cards (GTX 10-series etc.) work without an explicit override -- including in the Docker cuda target, where docker build has no GPU device to autodetect against in the first place. Real-only (no virtual/PTX): Pascal is now the oldest supported card, so it doesn't need to seed forward JIT compatibility for anything older the way the 75-virtual entry does for 7.5+. Verified end-to-end on a real GTX 1070 (sm_61): built the cuda Docker target with no --build-arg override, ran it with --gpus all, and confirmed via container logs that the GPU loaded the model and served a real synthesis request producing valid WAV output. Adjusts the Dockerfile comments and docs/DOCKER.md accordingly. * docker: pass through --max-prefill-tokens, add ref_text voice cloning - entrypoint.sh: forward MAX_PREFILL_TOKENS to --max-prefill-tokens, matching the existing optional-flag passthrough pattern - entrypoint.sh: a same-stem .txt next to a voice's .wav now supplies ref_text, enabling ICL clone mode instead of the x_vector_only fallback used when no transcript is given - switch voice registration's JSON construction from raw printf to jq for safe escaping of arbitrary transcript text; base64 payloads go through jq's --rawfile (not --arg) since large files blow past ARG_MAX as a command-line argument - add jq to all three runtime image stages (cpu/cuda/vulkan) for the above - docs/DOCKER.md: document both additions Verified end-to-end on a CPU build: both the ref_text and no-ref_text registration paths log correctly (ref_text=yes / ref_text=no) and /health responds after voice registration completes. * docker: opt-in fatal worst-case warmup synthesis ggml_backend_sched grows its compute buffer to fit the largest graph it has ever built and never shrinks it back, so VRAM use can ratchet up the first time a long reply arrives on live traffic. This adds an opt-in startup warmup: when WARMUP_VOICE is set, entrypoint.sh runs one real synthesis capped at WARMUP_MAX_NEW_TOKENS (default 750) frames after voice registration, forcing that worst-case decode/ codec-decode buffer growth to happen at startup instead of mid-request. Complements --max-prefill-tokens, which only covers the input side. Off by default (WARMUP_VOICE unset skips it entirely, matching every other optional flag in this entrypoint), and fatal on failure: if the warmup synthesis fails (most likely OOM), the container kills the server and exits non-zero rather than come up healthy and fail unpredictably later -- a deployment that can't afford its own configured worst case should know that at startup, not on a live request. Verified on a CPU build: warmup runs after voice registration, hits the configured frame cap exactly, and the container stays healthy. --------- Co-authored-by: Gary <gitea@gerasch.dev>	2026-08-07 07:52:22 +02:00
