38350d363e fix(backends): enable ROCm/HIP GPU offload for ggml audio backends (#10666) (#10667)
qwen3-tts-cpp, omnivoice-cpp, acestep-cpp and vibevoice-cpp shipped
rocm-* variants that silently ran on CPU ([Load] backend: CPU). Two
coupled defects:

- The Makefiles passed -DGGML_HIPBLAS=ON, but the vendored ggml only
  understands -DGGML_HIP=ON (GGML_HIPBLAS was removed upstream), so the
  ggml-hip backend target was never created and no GPU code was built.
- The CMake foreach that links the ggml GPU backends into the module
  listed blas/cuda/metal/vulkan but not hip, so even a built ggml-hip
  would not have been linked and its static backend registration would
  never run.

CUDA users were unaffected because cublas passes the correct GGML_CUDA=ON
and the foreach already links cuda. Mirror the proven llama-cpp hipblas
block (ROCm clang CC/CXX + AMDGPU_TARGETS) and add hip to each foreach.
Upstream picks the best device via ggml_backend_init_best(), so no
runtime flag is needed once HIP is compiled and linked.

cf71e291b4 fix(darwin): fix vibevoice-cpp build linkage + fail-safe go backend packaging (#10276)
* fix(darwin): never package a go backend build tree as a working image

The darwin/arm64 vibevoice-cpp image shipped the source tree with a
half-built CMake directory (build-libgovibevoicecpp-fallback.so/) and no
backend binary, so the backend could never start: run.sh exec'd a
vibevoice-cpp binary that was not in the package and LocalAI timed out
waiting for the gRPC service.

Two durable, backend-agnostic defenses:

- backend/go/vibevoice-cpp/Makefile: mirror whisper's cleanup discipline so a
  partial CMake tree cannot survive into packaging. Run `make purge` before
  each variant build and `rm -rfv build*` after. The old recipe only removed
  its build dir after a successful `mv`, so a failed build left the half-built
  tree behind.

- scripts/build/golang-darwin.sh: before creating the OCI image, remove any
  stray build-* directory and assert that the binary run.sh launches actually
  exists. A build that produced no binary now fails the job loudly instead of
  publishing a source tree as a working backend. The binary name is derived
  from run.sh's `exec $CURDIR/<binary>` line (parakeet-cpp launches
  parakeet-cpp-grpc, so it is not always ${BACKEND}) with a ${BACKEND}
  fallback.

The underlying native build failure that left vibevoice-cpp half-built still
needs to be reproduced and fixed on Apple Silicon; this change ensures such a
failure can never again be published as a working image.

* fix(vibevoice-cpp): build libvibevoice.a on darwin (link target, not path)

The darwin build failed with:

    No rule to make target 'vibevoice/libvibevoice.a', needed by
    'libgovibevoicecpp.so'.  Stop.

The upstream vibevoice project is added with add_subdirectory(... EXCLUDE_FROM_ALL),
so its `vibevoice` static-library target is only built when something links it
as a target. The Apple branch linked only `$<TARGET_FILE:vibevoice>` - a bare
archive path with no target reference - so CMake never emitted a rule to build
libvibevoice.a, while the Linux branch worked because it passes the `vibevoice`
target name inside the --whole-archive flags.

Link the `vibevoice` target on Apple (establishing the build dependency) and
apply -force_load as a separate link option to keep whole-archive semantics so
purego can dlsym the vv_capi_* symbols.

fe6eb57082 feat(vibevoice-cpp): add purego TTS+ASR backend (#9610)
* feat(vibevoice-cpp): add purego TTS+ASR backend

Wire up Microsoft VibeVoice via the vibevoice.cpp C ABI as a new
purego-based Go backend that serves both Backend.TTS and
Backend.AudioTranscription from a single gRPC binary. Mirrors the
qwen3-tts-cpp / sherpa-onnx pattern so the variant matrix
(cpu/cuda12/cuda13/metal/rocm/sycl-f16/f32/vulkan/l4t) and the
e2e-backends gRPC harness reuse existing infrastructure.

- backend/go/vibevoice-cpp/ - Makefile, CMakeLists, purego shim, gRPC
  Backend with model-dir auto-detection, closed-loop TTS->ASR smoke test
- backend/index.yaml - &vibevoicecpp meta + 18 image entries
- Makefile - .NOTPARALLEL, BACKEND_VIBEVOICE_CPP, docker-build wiring,
  test-extra-backend-vibevoice-cpp-{tts,transcription} e2e wrappers
- .github/workflows/backend.yml - matrix entries for all variants
- .github/workflows/test-extra.yml - per-backend smoke + 2 gRPC e2e jobs

* feat(vibevoice-cpp): drop hardcoded glob detection, add gallery entries

Refactor backend Load() to follow the standard Options[] convention
used by sherpa-onnx and the rest of the multi-role backends:
ModelFile is the primary gguf, supplementary paths come through
opts.Options[] as key=value (or key:value for Make-target compat),
resolved against opts.ModelPath. type=asr/tts decides the role of
ModelFile when neither tts_model nor asr_model is set explicitly.

Add gallery/index.yaml entries:
- vibevoice-cpp     - realtime 0.5B Q8_0 TTS + tokenizer + Carter voice
- vibevoice-cpp-asr - long-form ASR Q8_0 + tokenizer

Both pull from huggingface://mudler/vibevoice.cpp-models with sha256
verification. parameters.model + Options[] paths are siblings under
{models_dir} per the qwen3-tts-cpp convention.

Update Makefile e2e wrappers to pass BACKEND_TEST_OPTIONS comma+colon
style, and tighten the per-backend Go closed-loop test to use the
explicit Options API.

* fix(vibevoice-cpp): force whole-archive link so vv_capi_* exports survive

libvibevoice is a STATIC archive linked into the MODULE library.
Without --whole-archive (or -force_load on Apple, /WHOLEARCHIVE on
MSVC), the linker garbage-collects symbols not referenced from this
translation unit - which means dlopen+RegisterLibFunc panics with
'undefined symbol: vv_capi_load' at backend startup, since purego
looks them up by name and our cpp/govibevoicecpp.cpp doesn't call
them directly.

* test(vibevoice-cpp): rewrite suite with Ginkgo v2

Match the convention used by backend/go/sherpa-onnx/backend_test.go.
The suite now covers backend semantics that don't need purego (Locking,
empty-ModelFile rejection, TTS/ASR-without-loaded-model errors) on top
of the gRPC lifecycle specs (Health, Load, closed-loop TTS->ASR).
Model-dependent specs Skip() when VIBEVOICE_MODEL_DIR is unset, so
`go test ./backend/go/vibevoice-cpp/` is green on a clean checkout
and runs the heavyweight closed-loop spec when test.sh has staged
the bundle.

* fix(vibevoice-cpp): implement TTSStream + AudioTranscriptionStream

The gRPC server's stream handlers (pkg/grpc/server.go) spawn a
goroutine that ranges over a chan; the only thing closing that chan
is the backend's own *Stream method. With the default Base stub
returning 'unimplemented' and never touching the chan, the server
goroutine hangs forever and the client hits DeadlineExceeded - which
is exactly what the e2e harness saw in the test-extra-backend-vibevoice-cpp-tts
matrix run.

TTSStream synthesizes via vv_capi_tts to a tempfile, then emits a
streaming WAV header (chunk sizes 0xFFFFFFFF so HTTP clients can
start playback before the full PCM lands) followed by the PCM body
in 64 KB slices. The header + >=2 PCM frames satisfy the harness's
'expected >=2 chunks' assertion and give a real progressive stream.

AudioTranscriptionStream runs the offline transcription, emits each
segment as a delta, and closes with a final_result whose Text equals
the concatenated deltas (the harness asserts those match).

Two new Ginkgo specs guard the close-channel-on-error path so the
deadline-exceeded regression can't come back silently.

* fix(vibevoice-cpp): silence errcheck on cleanup paths

Lint flagged six unchecked Close()/Remove()/RemoveAll() calls along
purely-cleanup deferred paths. Wrap each in '_ = ...' (or a closure
for defers that take args) - matches what the rest of the LocalAI
backend/go/* tree already does for these callsites.

* fix(vibevoice-cpp): closed-loop slot fill + modelRoot-relative path resolution

Two bugs the test-extra-backend-vibevoice-cpp-* CI matrix surfaced:

1. Closed-loop Load with ModelFile=tts.gguf + Options[asr_model=...] left
   v.ttsModel empty, because the default-fill block only ran when BOTH
   slots were empty. vv_capi_load then got tts="" + a voice and the
   C side rejected it with rc=-3 'TTS model required to load a voice'.
   Fix: ModelFile fills the *primary* role-slot (decided by 'type=' in
   Options, defaulting to tts) independently of the secondary, so
   ModelFile + asr_model resolves to both.

2. resolvePath stat'd CWD before falling back to relTo. With LocalAI
   launched from a directory that happens to contain a same-named
   file, supplementary Options[] paths could leak away from the
   models dir. Drop the CWD probe entirely - relative paths now
   *always* join onto opts.ModelPath (the gallery convention).

New Ginkgo coverage:
  * 'ModelFile slot resolution' (4 specs) - asr_model+ModelFile, type=asr,
    explicit tts_model override, key:value variant.
  * 'resolvePath (relative-to-modelRoot)' (5 specs) - join, abs passthrough,
    empty input, empty relTo, and the CWD-trap regression test.
  * 'Load resolves relative Options paths against opts.ModelPath' - end-
    to-end gallery layout round-trip.

Verified locally: 19/19 specs pass (with model bundle, including the
closed-loop TTS->ASR; without bundle, 17 pass + 2 model-dependent skip).

* test(vibevoice-cpp): use gallery convention in closed-loop spec

The 'loads the realtime TTS model' / closed-loop specs were passing
already-prefixed paths into Options[]:

    Options: ['tokenizer=' + filepath.Join(modelDir, 'tokenizer.gguf')]

Combined with no ModelPath set on the request, the backend's
modelRoot fell back to filepath.Dir(ModelFile) = modelDir, then
resolvePath joined the prefixed Options path on top of it -
producing 'vibevoice-models/vibevoice-models/tokenizer.gguf' when
the CI's VIBEVOICE_MODEL_DIR is the relative './vibevoice-models'.

The fix is to mirror the gallery contract LocalAI core actually
sends in production: ModelPath is the models root (absolute),
ModelFile is a name *under* it, every Options[] path is relative
to ModelPath. Uses filepath.Base() to get bare filenames.

Verified locally with both VIBEVOICE_MODEL_DIR=/tmp/vv-bundle (abs)
and VIBEVOICE_MODEL_DIR=vibevoice-models (the relative shape that
broke CI). Both: 19/19 specs pass, ~55-60s.

* ci(vibevoice-cpp): switch ASR to Q4_K + bump transcription timeout

The Q8_0 ASR gguf is ~14 GB - too big to fit alongside the runner
image, the docker build cache, and the test artifacts on a free
ubuntu-latest GHA runner; 'test-extra-backend-vibevoice-cpp-transcription'
was getting SIGTERM'd at 90 min before the model could finish loading.

Switch to Q4_K (~10 GB on disk, slightly faster CPU decode) for:
  * the e2e harness Make target
  * the gallery 'vibevoice-cpp-asr' entry (parameters + files block)
  * the per-backend test.sh auto-download list

Bump tests-vibevoice-cpp-grpc-transcription's timeout-minutes from
90 to 150 - even with Q4_K, the 30 s JFK clip on a CPU runner needs
runway above the previous 90 min cap.

* ci(vibevoice-cpp): drop transcription gRPC e2e job - too heavy for free runners

The vibevoice ASR is a 7B-parameter model. Even on Q4_K (~10 GB on
disk) a single 30 s transcription saturates the per-test 30 min
timeout in the e2e-backends harness on a 4-core ubuntu-latest, and
the 10 GB download + Docker layer + working space leaves no headroom
on the runner's free disk. Two attempts in CI got SIGTERM'd at the
LoadModel boundary - the bottleneck isn't tunable from the workflow
side without a paid-tier runner.

The per-backend tests-vibevoice-cpp job already runs the same
AudioTranscription path via a closed-loop TTS->ASR Ginkgo spec - same
gRPC contract, same model, single process - so the standalone
tests-vibevoice-cpp-grpc-transcription job was redundant on top of
the disk/CPU pressure.

The Makefile target test-extra-backend-vibevoice-cpp-transcription
stays for local invocation on workstations that can afford it -
useful when developing the streaming codepaths.

* ci(vibevoice-cpp): restore transcription gRPC e2e on bigger-runner

Switch tests-vibevoice-cpp-grpc-transcription from ubuntu-latest to
the self-hosted 'bigger-runner' label that GPU image builds in
backend.yml use, plus the documented Free-disk-space prep step (purge
dotnet / ghc / android / CodeQL caches) the disabled vllm/sglang
entries in this file describe. That gives the 7B-param Q4_K ASR
model the disk + CPU runway it needs.

Keep timeout-minutes: 150 - even on a beefier runner the 30 s JFK
decode plus 10 GB download has to fit comfortably.

* ci(vibevoice-cpp): apt-get install make on bigger-runner before transcription e2e

bigger-runner is a self-hosted bare runner without the standard
ubuntu image's preinstalled build tools, so the previous job died at
the very first command with 'make: command not found' (exit 127).
Add the Dependencies step that the disabled vllm/sglang entries in
this file already document - apt-get installs make + build-essential
+ curl + unzip + ca-certificates + git + tar before the make target
runs. Mirrors how every other 'runs-on: bigger-runner' entry in
backend.yml prepares the runner.
