    It's not very far off at all. The only thing missing is FP64 support, and the hardware is very similar to Haswell (IVB is gen7, Haswell gen7.5).

    IIRC, the main difference is that Haswell has fewer hardware bugs; the FP64 code will need quite a few (more) workarounds for IVB.
    From looking at the different branches Igalia has at github for fp64 and va64 it looks like the roadmap may be: IVB fist, va64 (with GL 4.2) next.

    Huzzah! Ivy was not forgotten.
    cc to RussianNeuroMancer as he was interested too.

    This is great news. Hopefully we will be able to say the same soon about proper vulkan support.

    Great!

    Now what about the state of Vulkan support on Haswell hardware?

    If I read https://mesamatrix.net/ correctly (Intel Gen7 GPU is Haswell) the only thing holding back OpenGL 4.1, 4.2, 4.3, 4.4, and 4.5 support with Haswell is GL_ARB_vertex_attrib_64bit in OpenGL 4.1.

    If I remember correctly there was a huge jump in GPU peformance between Ivy Bridge and Haswell. Iris and Iris Pro introduced with Haswell were the first time the iGPU started to get interesting in my opinion

    From https://mesamatrix.net/ It looks like it will be a long time before Ivy Bridge sees OpenGL 4.0 support.
