AmigaOS 4: "VulkanOS4" offers implementation of Vulkan 1.3 API (update)
"VulkanOS4" brings the Vulkan graphics API to PowerPC Amiga hardware. It provides a complete Vulkan 1.3 runtime with two installable client drivers (ICDs), a loader library, and a full SDK for developing Vulkan applications on AmigaOS 4.
Vulkan is a cross-platform API and open standard for 3D graphics and computing. (Wikipedia).
The initial version 1.0.0 offers the following features:
- Vulkan 1.3 loader (vulkan.library) with automatic ICD discovery
and dispatch
- Software ICD (software_vk.library) with SPIR-V bytecode
interpreter, triangle rasteriser with depth testing, and
Bresenham line rasteriser
- GPU ICD (ogles2_vk.library) with OGLES2/Warp3D Nova backend and
SPIRV-Cross transpiler for SPIR-V to GLSL ES 3.1
- 218 Vulkan functions per ICD (100% Vulkan 1.3 core + WSI)
- 210+ SPIR-V opcodes including vertex/fragment shader operations,
matrix math, texture sampling, control flow, and type conversions
- 22 example programs from basic triangle to glTF model viewer
- SDK headers with AmigaOS interface definitions, inline macros,
and link library
- VulkanPrefs CLI tool for ICD priority management
- vulkaninfo device enumeration tool
- AmigaMark benchmark tool
- Autoinstall script for AmigaOS 4
- Optimised software rasteriser with incremental edge functions,
active varying mask, and shader state allocation pooling
- GPU ICD optimisations including VBO caching and batched resource
cleanup
The source code is available on GitHub.
Update: (21.03.26, 06:44, dr)
Version 1.1.0 provides SPIRV-Cross GPU ICD fixes and new example. All 23 examples verified on AmigaOne X5000/20 (P5020 2GHz, RX 560, RadeonRX 2.12).
Download: VulkanOS4.lha (version 1.1.0, still not available on OS4Depot, 2,5 MB) (dr)
