Phoronix: RadeonSI NIR Back-End Picks Up Support For More OpenGL Extensions

It was just a few days ago that Valve Linux developer Timothy Arceri enabled GLSL 4.50 support for RadeonSI's NIR back-end after previously taking care of tessellation shaders and other requirements. Now he has taken to implementing some other extensions in RadeonSI's NIR code-path...

So what is left now to enable Vulkan related extensions to support OpenGL 4.6?

It'd be nice if mesa matrix tracked this as well.

Isn't it beautiful to see different devs from various enterprises or just do-it-in-spare-time-for-fun-devs working on this driver and improving it?

In other news RedHat and others are pulling back the intel microcode updates due to the problematic quality. And Linus is not satisfied with the kernel related patches from intel:

Honestly, you wonder what t.f. intel was doing those 6 -7 months. (Besides Krzanich selling his shares in fall last year.) Now it's all like "OMG, we need to do something, nobody could've seen that coming". And, as we say in Germany, "It's done (sloppily) with a "hot needle"." I'm so glad I chose anything else but intel for the past 20 years...

Log a bug-report on its GitHub and you'll probably get an answer.

How's the performance of the NIR backend in comparison to the TGSI?

That'd be something very interesting to benchmark - if it can be done

Michael did benchmark it a couple of weeks back.

Now that it has GLSL 450, etc, I will benchmark it in next week or two.

Yeah, but IIRC the NIR backend was only supporting GL 3.x back then limiting the test to older applications. Since it did show somewhat faster performance than the "traditional" backend, I'd be interested to know if this remains the case with modern applications.
