Ok. I accept that. I’ll be more specific.
Forum post:
- Vulkan lavapipe software rendering is working on Haiku - #36 by amonpaike
“I managed to build Vulkan Loader, Mesa lavapipe (1), and renderheadless example. Headless software Vulkan rendering is working on Haiku.”. - commented by X512 - Vulkan driver - library and driver work by X512, as well as SwiftShader work by chaoticbob
Vulkan driver, demos, and Swiftshader work are shown on other forum threads…
I didn’t say or alluded to any availability of “3D accelerated graphics through hardware” yet. 
- Lavapipe is Mesa’s software-based Vulkan 1.2 implementation driver akin to LLVMpipe.
- The Gallium llvmpipe driver is a Mesa software rasterizer.
