    Phoronix: OpenGL ES 3.1 For Haswell Lands With Intel's Mesa Driver

    As a quick follow-up to OpenGL ES 3.1 coming for Intel Haswell graphics, those patches have now landed in Mesa Git...

    Just needs fp64 to get 4.4 opengl for haswell. I'm assuming the remaining GL_ARB_ES3_1_compatibility for 4.5 is trivial as ogl es 3.1 is done (some flags or just some minor API updates?).

      GL_ARB_ES3_1_compatibility should be enabled if you have compute shader support, which requires kernel 4.4 or later.

          I'm excited.

            What about a proper vulkan driver for haswell?

            does haswell even support GL 4.4? on windws it just supports 4.3

              It's happening, there's a steady stream of patches at the mailing list. Just give it a bit more time.

              Once fp64 (GL 4.0) and va64 (GL 4.1) are implemented, Haswell will have 4.5. Everything but those two is already implemented. And by that I mean literally *everything*. fp64 patches are in the process of review right now, but it's a huge patchset, 95 patches, so it might take a while still. Once that's done, va64 should follow quickly, it isn't as big.

                So? Sandy Bridge only supports OpenGL 3.1 on Windows and on Mesa it supports 3.3. The two Intel driver teams are different, and in fact the Sandy Bridge 3.3 support required a lot of work. I guess that on Windows they just didn't think it was worth it.

                  I'm pretty sure an Intel dev on this board said that the only graphics that isn't going to 4.5 is the SandyBridge ones, because the lack the hardware to do some stuff and they don't feel like baking it in software.

                  Besides, if you look at the tables with features, https://mesamatrix.net/ most stuff done is gen7+ (ivybridge), only a few are 8+ and they said they started with newer gens first.

                    I see, so is this just a documentation error then? Shouldn't it be changed in features.txt to hsw+? (it still says gen8+)
