AMD Developers Discuss Better Switching Of Radeon/AMDGPU CIK Support

Open-source AMD developers have been discussing in recent days how to better deal with the experimental support of GCN 1.1 "Sea Islands" (and GCN 1.0 "Southern Islands") support in AMDGPU and making it easier to enable while ensuring the Radeon DRM driver with its mature GCN 1.0/1.1 support doesn't interfere.

ARB_shader_ballot Lands For RadeonSI Mesa 17.1

Nicolai Hähnle has been busy today with Mesa Git as in addition to landing ARB_sparse_buffer for RadeonSI, he's now landed ARB_shader_ballot as another useful OpenGL extension -- it can be used as part of the "AZDO" techniques.

Radeon TONGA Sees Some Gains With AMDGPU DRM-Next 4.12

Over the past few days I have posted some RX 480 tests and R9 Fury OpenGL/Vulkan tests for the new AMDGPU code slated for Linux 4.12. I've also carried out some R9 285 "Tonga" tests and happy to report seeing some performance gains there too.

AMD's Radeon R9 Fury Showing Some Gains With AMDGPU's DRM-Next 4.12

On Friday I posted some early AMDGPU benchmarks of the DRM-Next code slated for Linux 4.12 using a Radeon RX 480 "Polaris" graphics card. As some additional reference points, here are some Linux 4.10 vs. 4.11 vs. (4.12; DRM-Next) code with an R9 Fury "Fiji" graphics solution.

More Radeon Vega Work Lands For LLVM 5.0

Yesterday we saw 100 patches adding Vega support to the Radeon DRM driver as well as 140 patches adding Vega support to RadeonSI Gallium3D. The other big piece of the open-source Linux driver stack for Vega is the AMDGPU LLVM changes.

SUSE Developers Publish Radeon GCN Backend Code For GCC Compiler

While the AMDGPU "GCN" compiler support in LLVM is quite mature now, the GNU Compiler Collection (GCC) hasn't yet received a full-fledged GCN compiler back-end for AMD GPUs. SUSE developers have been working on that for AMD and today they have published their code branch. This GCN back-end for GCC is primarily focused on compute capabilities rather than compiling graphics shaders.

xf86-video-ati 7.9 / xf86-video-amdgpu 1.3 DDX Driver Updates

Michel Dänzer of AMD has announced new releases of their X.Org DDX drivers: xf86-video-ati 7.9 and xf86-video-amdgpu 1.3. The changes in the updates are similar while the xf86-video-amdgpu DDX is paired to work with the AMDGPU DRM kernel driver while the xf86-video-ati driver continues on for the mature Radeon DRM.

Experimental Patches Revised For AMDGPU HDMI Stereo 3D, DAL/DC Now Supported

Last month an independent contributor to the AMD Linux graphics stack posted AMDGPU patches for HDMI Stereo 3D support within this open-source Radeon DRM driver. Those patches were rather dismissed in part because they didn't implement the support along the new DAL/DC display code-paths, but that has now changed.
