At long last the source code to the new AMDGPU driver has been released! This is the new driver needed to support the Radeon R9 285 graphics card along with future GPUs/APUs like Carrizo. Compared to the existing Radeon DRM driver, the new AMDGPU code is needed for AMD's new unified Linux driver strategy whereby the new Catalyst driver will be isolated to being a user-space binary blob with both the full open-source driver and the Catalyst driver using this common AMDGPU kernel driver.
Windows users this week saw the release of an AMD Catalyst 15.4 Beta driver, but if you're looking out for the equivalent Linux build, sadly it has yet to surface.
It looks like AMD might finally be close to publishing the code to their new AMDGPU kernel driver that's key to their new unified Linux driver strategy where their open-source stack and Catalyst share a common, open-source kernel driver.
It's been a while since last having any major breakthroughs to talk about for the open-source Radeon Linux graphics driver stack, but steady work continues. Some recent Mesa commits to Git highlight some code generation improvements.

AMD issued two job postings this past week for hiring more open-source Linux graphics driver developers.
While we're still waiting for AMD to release their new GPU kernel driver for supporting the existing R9 285 "Tonga" graphics card and their next-gen graphics cards coming out later this year, on the CPU side the AMD Linux developers have already started shipping patches to support their next-gen CPU architecture not expected for release until 2016~2017. Tux, meet the AMD Zen architecture.
It looks like AMD's next-generation Radeon R9 390X graphics card could end up retailing for $700+ USD, well more than the Radeon R9 290X and NVIDIA's GeForce GTX 980.
Early adopters of Ubuntu 15.04 Vivid Vervet can now use AMD's new Catalyst 15.3 Beta driver that's been packaged for Ubuntu and uploaded to the Vivid repository prior to its release on AMD.com.
It looks like in the next two weeks AMD will finally be releasing an updated Catalyst/fglrx graphics driver for Linux users.

Support for the GL_AMD_pinned_memory OpenGL extension has landed within Mesa and is implemented for the R600g and RadeonSI Gallium3D drivers. This patch series also lands the Userptr support for the open-source AMD graphics drivers on the user-space side.
Beyond the big set of AMD Radeon changes for Linux 3.20, Alex Deucher of AMD mailed in some important Radeon DRM driver fixes today that are a big deal for some R9 290 "Hawaii" users of the open-source driver.
Marek Olšák has implemented support for the GL_AMD_pinned_memory extension within Mesa/Gallium3D and the R600g and RadeonSI Gallium3D drivers.
Marek Olšák pushed out more RadeonSI Gallium3D driver improvements today for bettering the open-source Linux graphics driver support for the AMD Radeon HD 7000 series graphics cards and newer.
Alex Deucher has sent in his DRM-Next changes for the open-source Radeon graphics driver updates that will target the Linux 3.20 kernel.
Interstellar Marines is a science fiction FPS game in development that's powered by the Unity 4 Game Engine. While it's been available in early access mode for Linux gamers going back several months, the latest AMD Catalyst driver still seems to be having issues with this game.
The open-source Radeon DRM driver will finally support audio over DisplayPort for all relevant AMD GPUs.
Earlier this month I wrote about AMD preparing open-source HSA support for Carrizo APUs that aren't launching until later this year. Today more patches were published for the AMDKFD kernel driver in preparing for the forthcoming Volcanic Islands APUs.
