ci(release): build the linux vulkan bundle for arm64 - #31
Merged
Conversation
The release workflow ships a vulkan bundle for linux x64 but linux arm64 only gets cpu, so arm64 hosts with a Vulkan GPU have nothing to pin. Add a vulkan/arm64 entry to the build-linux matrix on ubuntu-24.04-arm. LunarG publishes no arm64 SDK apt repo, so the LunarG install step is gated to x64 and arm64 installs the toolchain from the Ubuntu archive: libvulkan-dev (loader/headers), glslc (shaderc, to compile ggml's compute shaders), and spirv-headers. glslangValidator is not required. 24.04 rather than 22.04 because glslc/shaderc is packaged on noble but not jammy -- the same reason the cuda job already uses 24.04. The entry produces parakeet-<ver>-bin-linux-vulkan-arm64.tar.gz like the others. Like every CI-built Vulkan/CUDA bundle it is GPU-unvalidated (the runners have no GPU); shader generation and linkage are exercised on the runner.

The release workflow ships a Vulkan bundle for linux x64 (and windows x64) but linux arm64 only gets a cpu bundle, so arm64 hosts with a Vulkan GPU have no prebuilt to pin.
This adds a
vulkan/arm64entry to thebuild-linuxmatrix on theubuntu-24.04-armrunner. LunarG publishes no arm64 SDK apt repo, so the LunarG install step is gated to x64 and arm64 installs the Vulkan toolchain from the Ubuntu archive instead:libvulkan-dev— loader + headersglslc(shaderc) — compiles ggml's compute shaders (find_package(Vulkan COMPONENTS glslc REQUIRED))spirv-headers— the SPIR-V registry headers (find_package(SPIRV-Headers CONFIG REQUIRED))glslangValidatoris not required.ubuntu-24.04-armrather than22.04becauseglslc/shadercis packaged on noble but not jammy — the same reason the cuda job already uses 24.04. The entry producesparakeet-<ver>-bin-linux-vulkan-arm64.tar.gz(and the matchinglib-bundle) like the other variants.Like every CI-built Vulkan/CUDA bundle this validates that the arm64 Vulkan backend builds — the runners have no GPU, so GPU execution is not exercised. Shader generation, the ggml Vulkan backend compile, and linkage are exercised on the native arm64 runner.
Validated end-to-end on a fork run with the free
ubuntu-24.04-armrunner: thevulkan/arm64job is green and attaches thebin-linux-vulkan-arm64+lib-linux-vulkan-arm64bundles; the x64 LunarG path is unchanged.
