Phoronix: R600 Gallium3D Shader Image Support Lands, Other R600g Patches Pending

As a follow-up to OpenGL 4.2 Support Could Soon Land For AMD Cayman GPUs On R600g, the patches have landed in Mesa 17.4-dev Git! Plus other R600g patches are on the mailing list for review...

In the process, this ends up taking Radeon HD 6900 "Cayman" GPUs to having OpenGL 4.2 compliance from 4.1 with the shader image support having been the last blocker. Other GPUs on R600g remain at OpenGL 3.3 due to lacking FP64 support, as outlined more extensively in that previous article.

But what about Cypress (HD 5800) and Aruba?

If you previously had 4.1, you now have 4.2. If you were stuck at 3.3, then you're still at 3.3 (but can safely override the level to 4.2 if you want).

I believe it is the other.

Aruba has hw FP64 support so you should get the new OpenGL4.2 support.
My Aruba (Richland) already had OpenGL 4.1

Good news, tho lack of FP64 support by most lower end GPU's from 5/6000 series will prevent them claiming 4.x compatibility.
