* ci(backend_build): plumb builder-base-image and BUILDER_TARGET build-args
Adds an optional builder-base-image input. When set, BUILDER_BASE_IMAGE
is forwarded as a build-arg AND BUILDER_TARGET=builder-prebuilt is set
to select the variant Dockerfile's prebuilt-base stage. When empty,
BUILDER_TARGET=builder-fromsource (the default) keeps the existing
from-source build path.
This makes the prebuilt-base optimization opt-in per matrix entry
without breaking local `make backends/<name>` invocations or backends
whose Dockerfile doesn't have a prebuilt path.

* ci(llama-cpp,ik-llama-cpp,turboquant): multi-target Dockerfiles for prebuilt + from-source
Restructure the three llama.cpp-derived Dockerfiles so each supports
two builder paths in a single file, selected via the BUILDER_TARGET
build-arg:
BUILDER_TARGET=builder-fromsource (default)
- Standalone build: gRPC stage + apt installs + (conditionally)
CUDA/ROCm/Vulkan + compile.
- Used by `make backends/llama-cpp` locally and any caller that
doesn't supply a prebuilt base.
BUILDER_TARGET=builder-prebuilt
- FROM \${BUILDER_BASE_IMAGE} (one of quay.io/go-skynet/ci-cache:
base-grpc-* shipped in PR #9737).
- Skips ~25-35 min of gRPC compile + ~5-10 min of toolchain installs.
- Used by CI when the matrix entry sets builder-base-image.
Final FROM scratch resolves BUILDER_TARGET via an aliasing FROM stage
(BuildKit doesn't support variable expansion directly in COPY --from),
then COPY --from=builder pulls package output from the chosen path.
BuildKit prunes the unreferenced builder, so each build only does the
work for the chosen path.
The compile RUN is identical between both builder stages, so it's
factored into .docker/<name>-compile.sh and bind-mounted into both.
ccache mount + cache-id stay per-arch / per-build-type.
Local DX preserved: `make backends/llama-cpp` (no extra args) defaults
to BUILDER_TARGET=builder-fromsource and works exactly as before.

* ci(backend.yml,backend_pr.yml): forward builder-base-image from matrix
Plumbs the new optional builder-base-image input from matrix into
backend_build.yml. backend_build.yml derives BUILDER_TARGET from
whether builder-base-image is set, so matrix entries that map to a
prebuilt base get the prebuilt path; entries that don't (python/go/
rust backends) fall through to the default builder-fromsource (which
their own Dockerfiles don't reference, so it's a no-op for them).

* ci(backend-matrix): wire builder-base-image to llama-cpp variants
For every entry whose Dockerfile is llama-cpp/ik-llama-cpp/turboquant,
add a builder-base-image field pointing at the appropriate prebuilt
quay.io/go-skynet/ci-cache:base-grpc-* tag.
backend_build.yml derives BUILDER_TARGET from this field's presence:
non-empty -> builder-prebuilt; empty -> builder-fromsource. So this
commit alone activates the prebuilt-base path for these 23 backends
in CI, while local `make backends/<name>` (no extra args) keeps the
from-source path.
Mapping by (build-type, arch):
- '' / amd64 -> base-grpc-amd64
- '' / arm64 -> base-grpc-arm64
- cublas-12 / amd64 -> base-grpc-cuda-12-amd64
- cublas-13 / amd64 -> base-grpc-cuda-13-amd64
- cublas-13 / arm64 -> base-grpc-cuda-13-arm64
- hipblas / amd64 -> base-grpc-rocm-amd64
- vulkan / amd64 -> base-grpc-vulkan-amd64
- vulkan / arm64 -> base-grpc-vulkan-arm64
- sycl_* / amd64 -> base-grpc-intel-amd64
- cublas-12 + JetPack r36.4.0 / arm64 -> base-grpc-l4t-cuda-12-arm64
Cold-build savings expected: ~25-35 min per variant (skips the gRPC
compile + toolchain install that's now in the base).

* ci: add base-grpc-l4t-cuda-12-arm64 variant for legacy JetPack entries
Two matrix entries (-nvidia-l4t-arm64-llama-cpp, -nvidia-l4t-arm64-
turboquant) build against nvcr.io/nvidia/l4t-jetpack:r36.4.0 + CUDA
12 ARM64. They're distinct from -nvidia-l4t-cuda-13-arm64-* which use
Ubuntu 24.04 + CUDA 13 sbsa. Add the missing JetPack-based variant
to base-images.yml so those two entries' builder-base-image mapping
in the previous commit resolves.
Bootstrap order before merging this PR (re-run base-images.yml on
this branch — 9 existing variants hit BuildKit cache, only the new
l4t-cuda-12-arm64 builds cold):

* ci: extract base-builder install logic into .docker/install-base-deps.sh
Pre-extraction, the apt + protoc + cmake + conditional CUDA/ROCm/Vulkan
+ gRPC install logic was duplicated across four files:
- backend/Dockerfile.base-grpc-builder (CI prebuilt-base source of truth)
- backend/Dockerfile.llama-cpp (builder-fromsource stage)
- backend/Dockerfile.ik-llama-cpp (builder-fromsource stage)
- backend/Dockerfile.turboquant (builder-fromsource stage)
A bump to e.g. CUDA toolkit packages had to be made in 4 places, and
drift between the prebuilt base and the variant-Dockerfile from-source
path was a real concern (ik-llama-cpp's hipblas branch was already
missing the rocBLAS Kernels echo that llama-cpp / turboquant /
base-grpc-builder all had).
Factor the install logic into a single .docker/install-base-deps.sh
that reads its inputs from env vars and runs conditionally on
BUILD_TYPE / CUDA_*_VERSION / TARGETARCH. Each Dockerfile now bind-
mounts the script alongside .docker/apt-mirror.sh and invokes it from
a single RUN step.
The variant Dockerfiles' grpc-source stage is removed entirely — the
script handles gRPC compile + install at /opt/grpc, and the
builder-fromsource stage mirrors builder-prebuilt by copying
/opt/grpc/. to /usr/local/.
Result:
- install-base-deps.sh: 244 lines (one source of truth)
- Dockerfile.base-grpc-builder: 268 -> 98 lines
- Dockerfile.llama-cpp: 361 -> 157 lines
- Dockerfile.ik-llama-cpp: 348 -> 151 lines
- Dockerfile.turboquant: 355 -> 154 lines
- Total Dockerfile bytes: 1332 -> 560 lines (58% reduction)
Bit-equivalence between prebuilt and from-source paths is now enforced
by construction: both invoke the same script with the same inputs.
A side-effect is that ik-llama-cpp now also gets the rocBLAS Kernels
echo + clblas block parity it was previously missing.
Includes the BUILD_TYPE=clblas branch (libclblast-dev) for parity even
though no current CI matrix entry uses it.
After this commit's force-push, base-images.yml needs to be redispatched
on this branch — the Dockerfile.base-grpc-builder content shifts so the
existing cache won't apply for the install layer (gRPC layer also
rebuilds since it's now in the same RUN step).

* ci(base-images): skip-drivers on JetPack l4t variant
cuda-nvcc-12-0 isn't installable via apt on the JetPack r36.4.0 base
image — JetPack ships CUDA preinstalled at /usr/local/cuda and its
apt feed doesn't carry the cuda-nvcc-* packages from the public
repositories. The original matrix entry for -nvidia-l4t-arm64-llama-cpp
on master sets skip-drivers: 'true' for exactly this reason; the
new base-grpc-l4t-cuda-12-arm64 base needs to match.
Also forwards SKIP_DRIVERS as a build-arg from matrix into the build
(was missing entirely before this commit).

The big RUN at line 268 of Dockerfile.llama-cpp re-runs from scratch on
every LLAMA_VERSION bump (or any LocalAI source change due to
COPY . /LocalAI just before). For CUDA-13 specifically that compile
recently hit the GHA 6h hard limit and failed:
https://github.com/mudler/LocalAI/actions/runs/25598418931/job/75148244557
Add a BuildKit cache mount on /root/.ccache and thread ccache through
CMake (CMAKE_C/CXX/CUDA_COMPILER_LAUNCHER) so most translation units
hit cache when their preprocessed source is byte-identical to the
previous build.
The cache mount is exported to the registry as part of the existing
cache-to: type=registry,mode=max in backend_build.yml, so it persists
across runs. mount id is keyed on TARGETARCH + BUILD_TYPE so different
variants don't thrash the same cache slot; sharing=locked serializes
concurrent writes.
Cold-build effect (first run after enable, or on LLAMA_VERSION bump
that touches every TU): unchanged. Hot-build effect (subsequent runs
with the same source, or LLAMA_VERSION bumps that touch a handful of
files): ~5-15 min for the llama.cpp compile vs the previous 1-3h cold.
For CUDA-13 specifically this should bring rebuilds well under the 6h
GHA limit.
Does NOT help the *first* post-bump build — that's still cold. For
that, follow-up work would be: (a) trim CUDA_DOCKER_ARCH to modern
GPUs only, (b) audit which CMake variants the published images
actually need, (c) pre-built CUDA+gRPC base image.
ccache package is already installed in the builder stage (line 90).

* feat(ci): allow routing apt traffic through an alternate Ubuntu mirror
Adds opt-in APT_MIRROR / APT_PORTS_MIRROR knobs to all Dockerfiles, the
Makefile, and CI workflows so we can fail over to a non-canonical Ubuntu
mirror when archive.ubuntu.com / security.ubuntu.com / ports.ubuntu.com
are degraded (recently observed: multi-day DDoS against the default pool).
Defaults are empty everywhere — behavior is unchanged unless a mirror is
configured. To enable in CI, set the repo-level GitHub Actions variables
APT_MIRROR (and APT_PORTS_MIRROR for arm64 builds). Locally:
make docker APT_MIRROR=http://azure.archive.ubuntu.com
A small POSIX-sh helper in .docker/apt-mirror.sh rewrites both DEB822
(/etc/apt/sources.list.d/ubuntu.sources, Ubuntu 24.04+) and the legacy
/etc/apt/sources.list before the first apt-get update. Dockerfile stages
load it via RUN --mount=type=bind, so there is no extra layer and no
cache invalidation when the script is unchanged. Reusable workflows also
rewrite the runner's own /etc/apt sources before any sudo apt-get call.

* ci(apt-mirror): default to the Azure mirror, visible in the workflow source
Bakes Azure (http://azure.archive.ubuntu.com / http://azure.ports.ubuntu.com)
in as the default for both Docker builds and runner-side apt — rather than
hiding the URL behind a GitHub Actions repo variable that's not visible
from the source tree.
A new composite action at .github/actions/configure-apt-mirror is the
single source of truth for runner-side rewrites. Five standalone
workflows (build-test, release, tests-e2e, tests-ui-e2e, update_swagger)
just `uses: ./.github/actions/configure-apt-mirror`.
Three workflows (image_build, backend_build, checksum_checker) keep an
inline bash rewrite, because they install/upgrade git via apt *before*
the checkout step (so the local composite action isn't loadable yet).
The Azure URL is visible in those files too.
The `apt-mirror` / `apt-ports-mirror` inputs of the reusable workflows
keep their now-Azure defaults — they still feed the Docker build-args
block in addition to the inline runner-side rewrite. Callers (image.yml,
image-pr.yml, backend.yml, backend_pr.yml) drop the previous
`vars.APT_MIRROR` plumbing and rely on those defaults.

* ci(apt-mirror): drop Force Install GIT, consolidate on the composite action
The PPA git upgrade ran add-apt-repository ppa:git-core/ppa, which talks
to api.launchpad.net — also part of Canonical's infrastructure and
currently returning HTTP 504. The Azure mirror only covers
archive.ubuntu.com / security.ubuntu.com / ports.ubuntu.com, not PPAs.
The system git that ubuntu-latest already ships is sufficient for
actions/checkout and the build pipeline, so just drop the upgrade. With
that gone, the apt-before-checkout constraint disappears too — all three
holdouts (image_build, backend_build, checksum_checker) can now switch
to ./.github/actions/configure-apt-mirror like the other five.
Net: 0 inline apt-mirror blocks, all 8 workflows route through the
composite action.

Add gfx1151 (AMD Strix Halo / Ryzen AI MAX) to the default AMDGPU_TARGETS
list in the llama-cpp backend Makefile. ROCm 7.2.1 ships with gfx1151
Tensile libraries, so this architecture should be included in default builds.
Also expose AMDGPU_TARGETS as an ARG/ENV in Dockerfile.llama-cpp so that
users building for non-default GPU architectures can override the target
list via --build-arg AMDGPU_TARGETS=<arch>. Previously, passing
-DAMDGPU_TARGETS=<arch> through CMAKE_ARGS was silently overridden by
the Makefile's own append of the default target list.
