    Phoronix: Mesa 19.1's New Features From The Intel Gallium3D Driver To New Drivers & Vulkan Optimizations

    Mesa 19.1 should be out any day now as the new quarterly feature release for this collection of open-source graphics drivers predominantly used on Linux systems. While we cover the Mesa development features on a near daily basis, here is a recap of all the exciting changes and new features to find with the upcoming Mesa 19.1.

          Thanks RussianNeuroMancer

          As of writing, the Radeon R600g driver side changes haven't landed to expose this soft FP64/INT64 support
          Does someone (phoronix) know whether this has happend yet?

            It hasn't, and no one is interested in getting it all working with the TGSI paths.

            Someone is working on NIR support for the r600g driver, and that has support for the soft fp64 support already in their branch. We'll have to wait and see if that ever gets merged into master, but it's currently a long way from being ready.

            /RANT
            It's really quite stupid that the r600g driver doesn't simply default to fake fp64 support in order to provide GL4. I don't think anyone is aware of any applications that attempt to actually use it, and it would have been very useful for a large number of games to expose GL4 by default. The app workarounds in drirc could be used if any are found. And the driver isn't good enough at passing conformance tests anyway (which is why GL4.4. and 4.5 aren't exposed on hardware with native fp64) so claiming to support fp64 wouldn't exactly hurt things there anyway.
