    Phoronix: Valve's ACO Shader Compiler Back-End For Radeon Vulkan Is Now In Good Shape For GCN 1.0

    As last minute material for Mesa 20.0 is making Valve's "ACO" AMD compiler back-end for the RADV Vulkan driver in better shape for GFX6/GCN1.0 graphics hardware...

    It's not the latest round of GFX6 fixes btw. The latest can be found here https://gitlab.freedesktop.org/mesa/..._requests/3533

      Indeed Michael. Now that the mesa-dev mailing list is no longer the default collaboration channel, you should subscribe to mesa's gitlab so that you are notified with regards to ongoing development activity.

        It's not really important though. ACO/GFX6 support should be merged for Mesa 20.0 pretty soon.

          Will we see Vulkan support with radeon driver? After all it is possible that AMD will ditch GCN1.0 cards from amdgpu soon.

            No it won't be ported to Radeon DRM compatibility.

              Well, granted, it's Sea Usland and GCN 1.1, bit my R9 290X is still sufficient for any game I throw at it so far (1200p :-P). I don't think GCN 1.0 cards are that much inferior, so they should be able to run most games at least somewhat playable ...

                BTW, does anyone know if Valve's ACO PPA (ppa:valve-experimental/mesa-bionic) is still getting updates?

                If not, what would be a good replacement? (Meaning one that doesn't try to upgrade everything but the kitchen sink and/or break unrelated packages in the process.)

                  Anyone know why mesa-git and mesa-aco-git havent been updated in a while on the AUR?

                  I used to use this one doesnt seem too bloated:

                    Ironic, given the recent information that they consider dropping SI from amdgpu.
