Phoronix: Intel's ANV Vulkan Driver Now Supports Tessellation Shaders

In addition to Mesa's "ANV" Intel Vulkan driver getting Float64 shader support this week, another important addition has made it into the latest Mesa Git code...

this is a important feature
good to see it supported

[Azpegath]

Will there be some sort of Mesamatrix for Vulkan? It would be very interesting to see, and to keep track of what is supported and what isn't.

does this apply for haswell too?

I believe so, didn't see any conditional statements regarding to exposing tesselationShader.

Yep, it works great on Haswell. I haven't actually tried Ivybridge, but it should all be there.

Do you know if vkQuake should now run on Haswell or what is missing?

(You can run it with the freely available shareware episode if you want to test it)

With Mesa 13.0.3 on Fedora 25 it always SEGFAULTs:

I'm not sure - Jason would be more likely to know. I know that vkQuake uses input attachments, and IIRC those weren't implemented in Mesa 13. They are in master. So it's worth a try...

How far is Tessellation support in radv off now that anv has it? Can anything be reused from the frontend?
