Phoronix: Intel's Mesa Driver Finishes Up Arrays of Arrays Support

Timothy Arceri has now fully-finished up the work on ARB_arrays_of_arrays OpenGL support for the Intel Mesa driver...

Now compute shader please!

[przemoli]

Anyone knows is piglits for this will become part of official conformance suite? IIRC AoA still lacked their tests, and where "worked on" last time someone from Khronos made update.

Yes, agreed. I'm not sure it's as important for Intel as it is for AMD, but still it's important enough.

[xxmitsu]

It's important for Intel to pass OpenGL ES 3.1 conformance as they are aiming now.

What it is needed to the gallium drivers support this extension now that it landed on mesa?

[duby229]

I think it just needs driver hooks. The way I understand it is that the classic interface essentially is the opengl state tracker. So for hardware to use that features of that state tracker it just needs the appropriate code in the driver so it can use it.

EDIT: Speaking of which, now that array of arrays is done the only thing left is compute shaders. Once drivers get to gl4.3 compliance they will probably have everything needed for a dx10-11 state tracker.

No driver hooks. Just a few things that couldn't occur in the GLSL IR before that now can, and need to be handled. The most annoying part will be its interaction with samplers.

FYI DX10 (and DX10.1) feature support has been complete for quite a while...

"Arrays of arrays" are one of those things that, once compiled down from high level GLSL into an IR, just becomes another way of addressing memory locations, and thus all that ought to be needed is to create the necessary GLSL-TGSI bridge.

Please correct me if I'm wrong.
