Three different background loops (_reconnectTask reachability poll,
_checkServeReachability, _pollBackgroundStatus) each independently
flipped Ollama sidecar tasks between running and stopped because the
`docker exec ollama-rocm ollama show <tag>` cmd exits cleanly after
its verification print, which the loops misread as the serve dying.
Added _isOllamaSidecarTask(task) and an early-bail in each of the
three loops so the task stays pinned to running once the show-cmd
exits 0. Also the tmux-graceful-kill path prepends a
`docker exec ollama-rocm ollama stop <tag>` before tearing down
the tmux session, so the Ollama-side model load gets unloaded too
(was leaving the model resident in the daemon after Stop).
Frontend half of the backend-detection + per-OS install command work,
plus a pile of mobile/UX fixes:
Backend awareness:
- _gpuEnvPrefix() picks CUDA_VISIBLE_DEVICES / HIP_VISIBLE_DEVICES /
nothing based on detected hwfit backend + scanned-host match (so a
stale ajax scan does not leak CUDA env vars into a kierkegaard
Vulkan launch). Replaces 6 hardcoded CUDA_VISIBLE_DEVICES sites.
- GGML_CUDA_ENABLE_UNIFIED_MEMORY only emitted when backend is
actually CUDA (was leaking onto Vulkan/ROCm via saved presets).
Per-target install command:
- Dep rows render a single mono command box + Copy button when the
server resolved pkg.install_cmd_for_target. Reused in the build-deps
install failure toast so the toast and the row show the same line.
- Diagnosis patterns split cmake/g++/git out of the generic
llama-cpp-python catch-all so a missing-cmake failure surfaces a
cmake-specific message + per-distro Copy buttons.
Form toggles always visible:
- Reasoning Parser, Expert Parallel, MoE Env Vars no longer gated on
model-family detection. Detection still hints (parser tag shown when
matched); toggle works with sensible defaults otherwise. MiniMax M-
series added to MoE family detector so the auto-fill is right.
Mobile + GPU default:
- Launch tab cached-list flex collapsed to 0px on mobile because the
desktop `flex: 1 1 0` had no parent height to grow into. Override
to `flex: 0 0 auto` in the cookbook mobile @media block.
- doclib-card expand on mobile (Firefox no :has() support) pins
explicit px heights so the launch form actually appears.
- llama_mode defaults to gpu when hwfit detected cuda/rocm/vulkan/
metal on the current target, instead of always cpu (which was
forcing -ngl 0 on first-open and burning 35GB models on CPU).
When a llama.cpp launch needs cmake/build-essential/git the user used to
get a four-distro dump ("apt: x / pacman: y / dnf: z / brew: w") and
had to pick the right one. Now:
- shell_routes /api/cookbook/packages probes /etc/os-release on the
target in the same SSH round-trip as the existing system-prereq
check, classifies into debian / arch / fedora / alpine / suse /
macos, and builds a single install_cmd_for_target string from the
(os_family, backend) matrix. CUDA hosts get nvidia-cuda-toolkit;
ROCm gets rocm-dev / rocm-hip-sdk; Vulkan gets libvulkan-dev /
vulkan-headers; etc.
- llama_cpp catalog entry gets system_prereqs: [cmake, g++, git].
When any of those are missing on the target, the row picks up
pkg.build_deps_missing + pkg.install_cmd_for_target for the
frontend to render.
- New POST /api/cookbook/install-system-deps endpoint runs the right
package manager via passwordless sudo on the target. Allowlisted to
{cmake, build-essential, g++, gcc, git, tmux, make}; sudo -n only
so it can never hang waiting for a password (returns a clear
"passwordless sudo unavailable" error via stderr instead).
Three classes of incorrect detection fixed:
(1) AMD GPU + no ROCm installed (e.g. Strix Halo) was reported as
backend=rocm everywhere, so launch commands emitted
HIP_VISIBLE_DEVICES (silent no-op on Vulkan) and the from-source
build path failed. Both _probe_amd_sysfs (routes/cookbook_routes)
and _detect_amd (services/hwfit/hardware) now probe rocminfo /
hipconfig / vulkaninfo at detection time and report vulkan when
only Vulkan is present.
(2) Build helper was picking the CUDA branch on AMD hosts whenever a
stray pip-installed nvcc was on PATH (vLLM wheels carry one
without libcudart). Added _odysseus_has_nvidia_hw() that checks
nvidia-smi / /dev/nvidia* / lspci, and gates both the nvcc PATH
augmentation and the CUDA elif branch on real hardware.
(3) Build chain reordered to ROCm/HIP > CUDA > Vulkan > CPU. Vulkan
tier added between CUDA and CPU as a portable fallback for hosts
with a GPU but no native toolchain (the common Strix Halo case).
Same _append_llama_cpp_linux_accel_build_lines also auto-attempts
sudo -n apt/pacman/dnf install of cmake/build-essential/git when
they are missing, surfacing a clear no-passwordless-sudo warning
otherwise.
Cookbook now needs to docker-exec into ollama-rocm (and any other sibling
container holding a model server) from inside its own container, so:
- Dockerfile installs the Docker CLI from the static binary tarball
(the Debian docker.io package ships dockerd but not the client on slim)
- docker-compose.yml bind-mounts /var/run/docker.sock and adds group_add
for the host docker group (default GID 963)
- entrypoint.sh detects the socket GID, creates a local group with that
GID, and runs usermod -aG before gosu-dropping to the app user so the
supplementary group propagates through (gosu strips by default)
