Phoronix: The Matrix Of Software Projects Mapping Khronos APIs From DXVK To Zink & CLVK

Neil Trevett, the president of the Khronos Group, presented at the X.Org Developers' Conference for the first time. During his presentation on Wednesday he covered their usual initiatives, how Khronos engages in open-source and open standards, and related bits -- plus a few interesting ones...

VK9 is really not progressing for a while and has been replaced by D9VK.

Typo:

DXVK, VK9, and VKD3D are commonly covered on Phoronix but also Zink is important too for running OpenGL over VUlkan

VK9 is really not progressing for a while and has been replaced by D9VK.

That's because VK9 was made entirely by one developer that doesn't have much free time.

Huh. No column for OpenGL over OpenGL ES. One of the mind-boggling enthusiasts in the community for the OpenPandora palmtop PC wrote one of those to help in porting pre-shader OpenGL stuff to it.

Pre-shader? The water shaders in OpenMW always seemed to work properly for me...

gl4es does only support basic OGL 2 shaders though, and doesn't support OpenGL 3, which does limit its use somewhat.

Even with the Panfrost Gallium driver which has pretty decent OpenGL 2 support, I do still find the GLESv1 backend of gl4es useful for working around some driver bugs.


But what about virgl? That can apparently run HL2, Portal, Left 4 Dead 2, Dota 2 and The Raven Remastered, at least to some extent, on OpenGL ES, but some static recompilation to ARM (as was done with Diablo II) would be required for it to not be CPU bottlenecked.

Dude working on it also actually said that the he is stopping his time developing it, few days later D9VK gets announced (if I remember right).

I would love to see clvk and clspv progress, as that may be the escape hatch AMD users would need to continue to run SYCL. It requires a massive input of effort though. Only the most basic things are operational.

So in theory e.g. Blender could run on a Zink (OpenGL over Vulkan) -> MoltenVK (Vulkan over Metal) stack on macOS?

EDIT: No, it can't since Zink is a Mesa Gallium 3D thing. GLOVE might be just the thing, though.

Huh. I was just going on the first paragraph from the README, which seems to be saying "no shader support at all":

This is a library provide OpenGL 2.x functionality for GLES2.0 accelerated Hardware (and of course also support OpenGL 1.5 function, sometimes better then when using GLES 1.1 backend) There is also support for GLES 1.1 Hardware, emulating OpenGL 1.5, and some OpenGL 2.x+ extensions, but without shaders.
