With yesterday's release of the new open-source "AMDGPU" Linux graphics driver stack we finally have a look at some of the hardware enablement code for the graphics processors of the upcoming "Carrizo" APUs.
As part of AMD finally releasing the AMDGPU kernel driver yesterday along with initial Iceland/Carrizo/Tonga support in Gallium3D, they also open-sourced a component formerly within the Catalyst proprietary driver.
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.
For those running older Radeon graphics cards with the R600 Gallium3D graphics driver, an important update landed in Mesa 10.6-devel Git this past week.
While AMD has yet to make the Catalyst 15.3 Beta Linux graphics driver available for download from their web-site, they released the driver to Canonical and as such this new AMD Linux driver has been available in Ubuntu 15.04 for a few weeks. Canonical is now back-porting this proprietary driver back into Ubuntu 14.04 LTS Trusty Tahr.
Tom Stellard of AMD has landed initial support into the AMD GPU LLVM back-end for the assembler and supporting inline assembly.
George Kyriazis of AMD has provided patches to the Blender project for vastly improving their OpenCL Cycles renderer support and allow for it to work with AMD GPUs.
Some Radeon DRM changes have already been queued for Linux 4.1 and now the AMDKFD HSA driver has its initial -next pull request for this next version of the Linux kernel.
With this month's release of the Catalyst 15.3 Beta for Windows, FreeSync Technology support was added. Unfortunately, it doesn't look like any Linux support is imminent.
The Linux 4.1 kernel will feature support for Radeon DisplayPort Multi-Stream Transport so that this open-source AMD Linux graphics driver can work with the latest high resolution DP displays and modern laptop docking stations.
A patch published on Sunday for the new AMDKFD HSA kernel driver adds support for using more than one graphics card/driver.
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.
Taiwanese SoC manufacturer MediaTek is said to be licensing AMD graphics technology for use in future high-end ARM SoC designs.
Another interesting announcement at GDC2015 yesterday besides the new Vulkan API, the Source 2 Engine, Unity 5, and more was AMD's LiquidVR announcement.
This month AMD is planning to finally make their Mantle graphics API more "open" by releasing a 450-page programming guide and API reference for Mantle.
AMD has released more details on their forthcoming "Carrizo" APUs from the IEEE International Solid-State CIrcuits Conference (ISSCC) in San Francisco.
After figuring out DisplayPort MST support for the open-source Intel graphics driver, David Airlie of Red Hat has moved on to publishing patches to the Radeon DRM driver for enabling DisplayPort Multi-Stream Transport.
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.
