Radeon RADV Driver Readied For Vulkan's Upcoming Mesh Shading Extension

[plonoma]

No, why would anyone develop something completely new in OpenGL when we have Vulkan?

That's a good question.
The thing is, developers still use OpenGL. Many even for new projects with a lot of modern features.
Some developers seem to treat the OpenGL API as a higher-level API compared to the Vulkan API, not as it's predecessor.

I think what RADV has achieved with RT till now is impressive because afaik AMD didn't provide to RADV devs proper RT documentation.

Yes but we will have RDNA3 cards soon and it will still be pretty useless.
Meanwhile NVIDIA users have been enjoying varying success with DLSS and RT for some time now, I saying varying because sometimes their drivers break the features and other times it doesn't always work with in proton games, according to reports. (bit of touch and go at times, as can be expected with closed-source drivers)

Awesome! Looking forward to it. But surely there will also be an OpenGL cross-vendor mesh shading extension to go along with the Vulkan one?

It has been officially confirmed that a Vulkan cross-vendor mesh shading extension is coming soon.

Still waiting for RADV RT to be on par with Win10. (or close) ATM it's still experimental with crash/freeze galore!

tuxd3v If you mean what hardware supports mesh shaders then i think you would need RDNA2.
If you mean RADV in general then any GPU that can utilize the AMDGPU kernel driver is supported. Which includes GCN 1.2

[tuxd3v]

What is the hardware supported by Radv?
Does GCN1.2 supports it, or there are a higher base request for hardware?
thanks

Also, any games that already make use of mesh shaders?

Thank you. I am not aware of any current games that use mesh shaders, but we hope that adding driver support for these shaders may motivate developers to consider mesh shading in the future.

Since no-one of our great Phoronix community felt compelled enough to congratulate & thank You for Your invaluable work You do for all us plebs, let me be the first one here:

Thanks!

Also, any games that already make use of mesh shaders?

from searching, the only one i can find is a game called "Justice Online." outside that, with the UE5 tech demo "The Matrix Awakens" and 3DMark Mesh Shading benchmark.
