I can do it the next 2 days and then come back to you. If thats OK for you. Today and tomorrow I am busy with other stuff. Like doing adjustments to get it run on Haiku with Vulkan.

A bit early:
For interface look here:
Currently its missing:
- Geometry Buffers for Deferred Shading
- PBR shader fixes
- Speed improvements
- some other improvements
The editor looks like:

How complicate would it be to get this Zink thing running?

Probably better to test with vulkan, zink adds a layer of complexity thatās not needed just yet. But iirc, zink shouldnāt be crazy to get working over top of vulkan

Zink compiles, but I am not sure how to enable it. Haiku currently use custom add-on system for Mesa OpenGL that may be the problem.
What is Zink from architecture point of view? Something statically compiled to libGL.so? Separate add-on file (if so what system is used for loading?)? No additional files were produces in install directry after enabling it, only mesa-master/build.x86_64/src/gallium/drivers/zink/libzink.a.

on linux it should be a string enviorment saying to use zink on vulkan instead of mesaās native openGL
but Iām not quite sure I havenāt checked
https://docs.mesa3d.org/drivers/zink.html
It seems DRI add-on zink_dri.so. Haiku Mesa OpenGL currently use its own add-on system with only softpipe add-on present.

Thereās my favorite: Warzone 2100. Their website is https://wz2100.net and the source is on GitHub. Itās better than Warcraft 3 in my opinion.

I managed to compile libgallium_dri.so, it seems to contain Zink.

Yes. For games like: Doom II, WarHammer 40000, MegaGleist, The Talos Principle, F1 2017, X-Plane 11, etcā¦
AMDGPU(-PRO) 21.0.0 driver for Haikuā¦ worth it.

What windowing system integration it use? SDL? GLFW? Per OS native API?

Integrating VideoStreams VideoProducer interface to both Vulkan WSI and Mesa winsys/DRI will makes life easier and allows to use Zink DRI driver.

I found that RADV driver supports VkImportMemoryHostPointerInfoEXT Vulkan extension that allow to create GPU buffers from CPU pointers. It can be used to register BBitmap directly as GPU GTT buffer and avoid all memcpy()'s.

That sounds amazing! Nice!

RetroArch has quite a lot of things that one could potentially play around with for testing:
-Vulkan driver (software rendered cores like bsnes or 3d rendered cores like Dolphin)
-OpenGL driver (pair it with Zink?)
-D3D11 driver (pair it with DXVK?)
-Tons of shaders at every level of complexity, from bicubic to full-blown CRT emulation
-G-Sync/FreeSync as well as good old VSync
Just asking about Zink since my engine is OpenGL at the time being but does push OpenGL 4.6 stuff if present. Would be interesting (maybe only for me) where it goes and it does not require any fancy windowing system (native BeOS).

I implemented RadeonGfx driver server mode and now it is possible to run multiple processes that use 3D acceleration. Because of GFX ring reset hack, command buffer scheduling is limited and only one command buffer can be executed at moment of time.
