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.
