Vulkan runs as a CPU software implementation: Mesa +lavapipe (the `vulkan-swrast` driver) provides a real Vulkan compute queue over llvmpipe's LLVM CPU +JIT, so no host GPU is required. The on-target StarryOS gate builds and runs the native C and C++ +carpets; the Rust (ash) and Python (pyvulkan / kompute) cells are exercised in the host reference +layer. Each cell enumerates the Vulkan compute API surface against the real `vulkan_core.h` / Vulkan +spec, dispatches GLSL compute shaders and checks every result element against a numpy or closed-form +reference, and drives the error paths against real `VkResult` enums. A cell prints ` OK ` +only when its failure count is zero and the assertion total equals a pinned `EXPECTED` constant. + +## Cells and assertions + +| Cell | Binding | Assertions | Runs | +|:--|:--|--:|:--| +| `vulkan_c` | Vulkan C API (`vulkan/vulkan.h`) | 114 | on-target (all arches) + host | +| `vulkan_cpp` | Vulkan-Hpp (`vulkan/vulkan.hpp`) | 54 | on-target (all arches) + host | +| `vulkan_rust` | ash 0.38 | 115 | host reference | +| `vulkan_py` | pyvulkan + numpy | 191 | host reference | +| `kompute_py` | Kompute (`kp`) + numpy | 72 | host reference (x86_64 / aarch64) | + +Total: 546 assertions. + +Each cell covers the compute API end to end: instance / physical-device / device / queue / buffer / +device-memory (map / flush / invalidate) / shader-module / descriptor-set-layout / pipeline-layout / +compute-pipeline / descriptor-pool / command-buffer / fence / semaphore / event / query-pool / +push-constant / dispatch / indirect-dispatch / timestamp / transfer commands, plus the core-1.1 `*2` +queries. The operators (vector-add, saxpy, element-multiply, local-memory reduction and the derived +kernels) are dispatched as real GLSL compute shaders and every output element is compared to the +closed-form / numpy reference with a relative tolerance. Boundary cases (tail guards, +oversubscription, corrupt SPIR-V, bad memory-type indices) and error paths are asserted directly; +where lavapipe has no validation layer and permits a case the assertion records it as PERMITTED or a +non-counting skip rather than faking a rejection. + +## Backend and runtime + +Provisioned from Alpine edge (main + community) as musl packages: `mesa-vulkan-swrast` (lavapipe), +`vulkan-loader`, `vulkan-headers` and `glslang` / `shaderc` (GLSL to SPIR-V), plus the `llvm-libs` +closure lavapipe links against. Alpine edge builds `mesa-vulkan-swrast` for all four target +architectures (x86_64, aarch64, riscv64, loongarch64), so the C and C++ carpets run on-target on +every arch. `prebuild.sh` cross-compiles them against the provisioned musl headers/libraries under +qemu-user, compiles the GLSL shaders to SPIR-V, and stages the binaries plus the mesa closure into +the per-arch rootfs. `programs/run_all.sh` runs the native carpets and prints `TEST PASSED` when +every built carpet reports `OK` and none fails. + +Runtime environment on target: + +- `XDG_RUNTIME_DIR` must point at a writable directory; lavapipe maps host-visible memory through a + file under it. +- `VK_DRIVER_FILES` selects the lavapipe ICD; the ICD JSON's absolute `library_path` resolves + against the rootfs root. +- `LP_NUM_THREADS=1` pins the mesa thread pool to one thread, matching StarryOS's single vCPU. + +## Host reference layer + +The Rust, Python and kompute cells run in the host reference layer only: their language runtimes +(rustc/cargo, CPython + pyvulkan/kompute) are not part of the musl on-target provisioning. On the +host they run against the same lavapipe device the on-target C/C++ cells use: + +- `vulkan_rust` (ash 0.38) and `vulkan_py` (pyvulkan) load the lavapipe ICD directly. +- `kompute_py` uses the Kompute Python binding. Kompute's prebuilt binaries are glibc x86_64 / + aarch64 only (conda-forge builds no `linux-riscv64` / `linux-loongarch64` kompute, and its sdist + needs a full Vulkan SDK + CMake to build). Its runtime coverage is therefore host-side on x86_64 / + aarch64; the same Vulkan compute path is covered on every arch on-target by `vulkan_c` / + `vulkan_cpp`, which drive the raw Vulkan API rather than the kompute wrapper. + +## Single-core execution + +StarryOS runs on one vCPU (SMP is off by default), so lavapipe's llvmpipe JIT executes every +workgroup on a single thread. `run_all.sh` pins the mesa thread pool with `LP_NUM_THREADS=1` and +prints the detected CPU count, so the single-core reality is explicit in the output. The carpets +assert numerical correctness and API ordering semantics, not throughput; the results are independent +of thread count. "Multi-queue" on lavapipe (`queueCount == 1`) is exercised as asynchronous +multi-submit rather than hardware-parallel queues, and is asserted as such. + +## Run + +``` +cargo xtask starry app qemu -t gpu-vulkan --arch x86_64 +cargo xtask starry app qemu -t gpu-vulkan --arch aarch64 +cargo xtask starry app qemu -t gpu-vulkan --arch riscv64 +cargo xtask starry app qemu -t gpu-vulkan --arch loongarch64 +``` diff --git a/apps/starry/gpu-vulkan/build-aarch64-unknown-none-softfloat.toml b/apps/starry/gpu-vulkan/build-aarch64-unknown-none-softfloat.toml new file mode 100644 index 0000000000..ced8f2e4a3 --- /dev/null +++ b/apps/starry/gpu-vulkan/build-aarch64-unknown-none-softfloat.toml @@ -0,0 +1,13 @@ +features = [ + "ax-runtime/display", + "ax-runtime/rtc", + "ax-driver/virtio-blk", + "ax-driver/virtio-net", + "ax-driver/virtio-gpu", + "ax-driver/virtio-input", + "ax-driver/virtio-socket", + "starry-kernel/input", + "starry-kernel/vsock", +] +log = "Warn" +target = "aarch64-unknown-none-softfloat" diff --git a/apps/starry/gpu-vulkan/build-loongarch64-unknown-none-softfloat.toml b/apps/starry/gpu-vulkan/build-loongarch64-unknown-none-softfloat.toml new file mode 100644 index 0000000000..b118a81f50 --- /dev/null +++ b/apps/starry/gpu-vulkan/build-loongarch64-unknown-none-softfloat.toml @@ -0,0 +1,14 @@ +target = "loongarch64-unknown-none-softfloat" +log = "Warn" +features = [ + "ax-runtime/display", + "ax-runtime/rtc", + "ax-driver/serial", + "ax-driver/virtio-blk", + "ax-driver/virtio-net", + "ax-driver/virtio-gpu", + "ax-driver/virtio-input", + "ax-driver/virtio-socket", + "starry-kernel/input", + "starry-kernel/vsock", +] diff --git a/apps/starry/gpu-vulkan/build-riscv64gc-unknown-none-elf.toml b/apps/starry/gpu-vulkan/build-riscv64gc-unknown-none-elf.toml new file mode 100644 index 0000000000..75531a504f --- /dev/null +++ b/apps/starry/gpu-vulkan/build-riscv64gc-unknown-none-elf.toml @@ -0,0 +1,14 @@ +features = [ + "ax-runtime/display", + "ax-runtime/rtc", + "ax-driver/serial", + "ax-driver/virtio-blk", + "ax-driver/virtio-net", + "ax-driver/virtio-gpu", + "ax-driver/virtio-input", + "ax-driver/virtio-socket", + "starry-kernel/input", + "starry-kernel/vsock", +] +log = "Warn" +target = "riscv64gc-unknown-none-elf" diff --git a/apps/starry/gpu-vulkan/build-x86_64-unknown-none.toml b/apps/starry/gpu-vulkan/build-x86_64-unknown-none.toml new file mode 100644 index 0000000000..a8c92b85d8 --- /dev/null +++ b/apps/starry/gpu-vulkan/build-x86_64-unknown-none.toml @@ -0,0 +1,9 @@ +target = "x86_64-unknown-none" +log = "Warn" +features = [ + "ax-driver/virtio-blk", + "ax-driver/virtio-net", + "ax-driver/virtio-gpu", + "ax-driver/virtio-input", + "ax-driver/virtio-socket", +] diff --git a/apps/starry/gpu-vulkan/prebuild.sh b/apps/starry/gpu-vulkan/prebuild.sh new file mode 100755 index 0000000000..0bf55ca667 --- /dev/null +++ b/apps/starry/gpu-vulkan/prebuild.sh @@ -0,0 +1,158 @@ +#!/usr/bin/env bash +# prebuild.sh - provision the software Vulkan compute runtime (Mesa lavapipe / llvmpipe + the Vulkan +# loader) and the compiled Vulkan compute carpet binaries into the per-arch Alpine rootfs. +# +# Portable model: extract the base Alpine rootfs to a staging tree, `apk add` mesa-vulkan-swrast +# (lavapipe, the CPU software Vulkan driver), vulkan-loader, glslang/shaderc (GLSL -> SPIR-V) and the +# build toolchain INTO it via qemu-user-static (apk resolves every package for the TARGET arch on an +# x86 build host - no drifting URLs, no cache-miss-exit), cross-compile the Vulkan C and C++ carpet +# sources against the provisioned musl headers/libraries with the target gcc under qemu-user, compile +# the GLSL compute shaders to SPIR-V, then copy the shared-library closure, the lavapipe ICD metadata +# and the carpet binaries + runner into the overlay.
