AMD RadeonSI Gallium3D Is Now Incredibly Close To OpenGL 4.3!

[geearf]

One very advanced patch is missing for 4.2: https://lists.freedesktop.org/archiv...il/112547.html :-)

I wonder why it didn't go with this final patchset for 4.2.

It would be not surprising if Radeon ( and possibly others ) get full GL 4.5 this calendar year

It would be not surprising if Radeon get full GL 4.5 this summer

GL_ARB_clear_texture at last one month, according to https://www.phoronix.com/forums/foru...839#post863839

sorry, i was not clear on this.
i meant there is at least one month between now and feature freeze, not that this ext needs one month of work

Too much green, I cannot see anymore... x_X

Congratz guys !!

On the other hand, compute shaders don't work really well with e.g. these examples anyway. https://github.com/McNopper/OpenGL/
For example here is an apitrace for example30 that shows a raytracing scene on intel with MESA_GL_VERSION_OVERRIDE=4.3 MESA_GLSL_VERSION_OVERRIDE=430, but on radeonsi it just shows gray window content (with no error message this time): http://haagch.frickel.club/files/McN...xample30.trace

On the other hand, example40 works fine on radeonsi, but is pretty broken (but at least displays something) on intel. I've reported this here, because it seemed like a nice small test case: https://bugs.freedesktop.org/show_bug.cgi?id=94858

Yeah, you can't exactly claim 4.2 support if you don't actually *claim* 4.2 support.

Can't wait to see Unreal Engine 4 running with OpenGL 4.3 on free drivers!

Still doesn't work with the upcoming opengl 4.3 support, ut4 just shows a completely white window.

Congratulations AMD devs! We can clearly see here the realization of all the previous months of efforts.
And now, radeonsi is now the only driver implementation officially compatible with OpenGL 4.2!

It's nice to see all the green cells in https://mesamatrix.net

Wooo!
And only one part of an extension by tarceri left for 4.4. So the next Mesa release will probably be a two-GL-version leap again!
So currently we are still four years behind, but soon enough it will be only three, so the gap is getting bridged!

And thanks to this AMD sprint, as soon as compute shaders land, there should be some interesting results in both benchmarking and usability. Can't wait to see Unreal Engine 4 running with OpenGL 4.3 on free drivers!

EDIT: In addition, looking at 4.5, looks like it's almost done too! The KHR_robust* should be fairly easy to base off the ARB variants that exist now, GL ES 3.1 is already in Mesa since a few months ago, and the remaining cull_distance extension is already being worked on!
