  • The New AMD GPU Open-Source Driver On Linux 4.2 Works, But Still A Lot Of Work Ahead

    Phoronix: The New AMD GPU Open-Source Driver On Linux 4.2 Works, But Still A Lot Of Work Ahead

    With the Linux 4.2 kernel settling down nicely and AMD developers having already sent in a few round of fixes for their new AMDGPU kernel DRM driver, I've started testing out this new kernel driver -- plus the new xf86-video-amdgpu DDX and the associated new Mesa/LibDRM code -- that is providing the open-source accelerated graphics support for Tonga and all new/future GPUs like Carrizo and Fiji.

    openSUSE users can add three repository to get amdgpu driver

    Code:
    zypper ar http://download.opensuse.org/repositories/home:/pontostroy:/X11/openSUSE_%NAME/ pont-x11
    zypper ar http://download.opensuse.org/repositories/home:/pontostroy:/amdgpu/home_pontostroy_X11_openSUSE_%NAME%/ amdgpu
    zypper ar http://download.opensuse.org/repositories/home:/pontostroy:/drm-next/openSUSE_%NAME reponame pont-kernel
    copy new firmware and run mkinitrd

        Good to know it's working nicely on openSUSE with these repos, wasn't aware of them.

          Using Oibaf PPA and kernel 4.1.3 I can enable Unigine Heaven with Tesselation, using MESA_GL_VERSION_OVERRIDE=4.0.

          The performance is still low, but it works right now without any glitches. The card is a R9 290.

          Unfortunately I can't make Steam work with the version override, so can't test if Metro Redux or Bioshock Infinity are working with the radeonsi driver yet.

            Wait, I'm confused. I thought that AMDGPU was only for cards with GCN 1.2 and up. How are Pontostroy and [email protected] talking about using it on the HD 7790 and R9 290?

              There's a kconfig option to enable olde GCN support just for testing the driver but it's not meant for replacing lonterm stable functionality.

                You don't need 4.0 override for Unigine Heaven, it use tessellation extension without the need for OpenGL 4 context.

                You can try it also on Kabini and Kaveri APUs as all those are GCN 1.1... but support for those is just for testing and is less stable then radeon.

                  What advantages does xf86-video-amdgpu have over the modesetting driver again? (Not that it affects me as a wayland user - or does it?)

                    I wonder the mesa drivers are so weak.
