AMD Publishes Open-Source "Stoney" APU Graphics Support

AMD has published their initial open-source driver support for the "Stoney" APU graphics.

AMD's Alex Deucher describes Stoney as, "this patch set adds support for the new Stoney APU. Stoney is a new VI-based APU from AMD." With being part of the Volcanic Islands series, the support is added to the new AMDGPU kernel DRM driver. Stoney is derived from the latest Carrizo APU graphics but with some upgrades.

The AMD Stoney enablement includes UVD 6, VCE 3, Dynamic Power Management, etc. The PCI ID of Stoney is 0x1002.

The AMDGPU DRM enablement can be found via this patch series and hopefully will still land in time for merging into the Linux 4.4 kernel, but that's yet to be confirmed. Patches are also out for the minimal Mesa changes and xf86-video-amdgpu. There's also new Stoney firmware blobs needed for the hardware support.
