Phoronix: Zink On Mesa 21.1-devel Now Achieves OpenGL 4.3 Over Vulkan

Going back to last summer there have been patches for getting OpenGL 4.6 with the Zink GL on Vulkan implementation but were considered experimental and not for immediate upstreaming. In the months since and especially after Mike Blumenkrantz was hired by Valve, the upstreaming effort kicked into higher gear. Now with Mesa 21.1, we are up to OpenGL 4.3...

Wow, that's impressive!

Do someone knows an easy way to test Zink? I would like to add it to the systems I test for Unvanquished ( https://wiki.unvanquished.net/wiki/G...ibility_matrix ).

Ill have to check in the morning, but I have an old laptop that I believe supports the vulkan extensions necessary, but is stuck on opengl 3.2, not that i use anything to my knowledge that needs higher, but itll be pretty cool anyway
I just need to find apps to test

[microcode]

Ah yes, the ol' bumperoo, I know it well.

Zink is part of MESA so everything should already be in place.

Typo:

For OpenGL 4.4 there is just ARB_buffer_storag,

I am thinking... whether ARB_gl_spirv could be done by simple translation/near-passthrough...

I am sorry that is not going to make much difference. That only helps with modern opengl applications that use spirv. Last look 99%+ of opengl applications still us glsl that require the conversions zink is doing now.

to think this get more support than any intel drivers

I am sorry see how you always counter every post I make? Is there any reason why?

I know nobody uses that extension (and I doubt anybody will)!

My (very limited) understanding is that OpenGL is sort of frozen now at 4.6 and that is kind of the end of it. As I think already well enough know, if Zink could hit 4.6 with acceptable performance, GPU vendors would just need to have Vulkan drivers, and OpenGL could happen via Zink. Is this close to why this would be useful?

I suppose this could loosely be like XWayland is to XOrg Server (as a whole) to Wayland. Wait, should I go grab some popcorn?
