    Phoronix: AMD Kaveri Gets A Big Performance Boost With Mesa 18.2 & AMDGPU DRM

    When using the latest Git/development code of Mesa 18.2 on Kaveri APUs you may find up to a 2x increase in performance if you are using the AMDGPU DRM driver rather than the default Radeon DRM driver...

    Should this really be fixed in the kernel instead?

        Funny story and nobody noticed? :-)

          I wonder if they have the same issue on Windows side as well :-))

            Or if such issues exist on other chips, too.
            Well, good that this is fixed.
            Stop TCPA, stupid software patents and corrupt politicians!

              The comment in the code before this commit was:
              /* KV should be 0x00000002, but that causes problems with radeon */
              So I'm pretty sure someone noticed before. The difference now is that "2" is working with the amdgpu kernel module.

                If they have the same Issue with other cards and on other OS. Vega could be so fast, that "poor Volta" could be real...

                  So instead of fixing radeon, they crippled the performance ... also a solution ...

                    In related news, AMD now plans to disable amdgpu DC on Kaveri by default: https://lists.freedesktop.org/archiv...ay/022021.html
                    Because they have no hardware to test LVDS/VGA. Which apparently wasn't a problem before amdgpu DC or with radeon?
