    Phoronix: OpenGL 3.3 / GLSL 3.30 Lands For Intel Sandy Bridge On Mesa

    Now that OpenGL geometry shaders landed for Intel Sandy Bridge hardware in Mesa and the OpenGL version bumped to 3.2, OpenGL 3.3 has arrived...

    Nice. Pretty much done with Sandy. Working further to enable GL4 on Sandy imo isn't worth it. Imo the devs should instead do the preliminary/preparatory work for GL-Next support on Sandy since from what I got from the Khronos hints - GL-next will require GL3+ hardware, so apparently Sandy qualifies for it.

      So it didn't land in Mesa 10.3? Will it be queued for 10.3.1?

        @mark45: It can't get to 4.0, as it lacks support for hardware tessellation, various shader model 5 features, etc, and they aren't sensible to emulate. There's a few more driver-side extensions from 4.x which can be usefully enabled (program interface query, internalformat query 2, dsa, etc...).

          some news about OpenCL on sandy bridge?
          Beignet should not suport for now.
          Maybe some day gallium will support?
          The upcoming chip architecture will integrate Intel's best graphics chip technology to date directly onto the central processing unit.

            IIRC, even on Windows, when I install driver from Intel, it installs OpenCL that runs on the CPU, not GPU. It's possible that SNB Graphics is not OCL capable.

              Doesn't this put Linux's OpenGL support on SB ahead of the Windows drivers (which only expose 3.1 IIRC)?
              Is that a first for mainstream consumer hardware?

                I think it's similar to r700 on the radeon side, which means you could potentially hack together some kind of partial OpenCL support but the hardware really doesn't support it.

                I highly doubt you'll ever see anything for SNB. It's not that fast, anyway.

                  Looks like that, but keep in mind their Windows driver does support GL_ARB_compatibility while Mesa isn't.

                    Intel Gen4, yes that old crap, Mesa driver also supports more OpenGL features than the Windows one and has higher performance.
