Most pre-GCN AMD graphics cards are still limited to OpenGL 3.3 support at this time due to not supporting FP64. Only the HD 5800/6900 series on R600g currently have real double-precision floating-point support working right now so at present they are on OpenGL 4.3 rather than 3.3, but those other generations may be catching up soon thanks to the "soft" FP64 code...

Mesa 17.3.3 is now available as the latest point release for the Mesa 17.3 stable series...

Towards the end of December AMD quietly released ROCm 1.7.60 as the newest version of their Radeon Open Compute stack complete with their maturing OpenCL implementation. With the improvements there plus NVIDIA recently introducing their 390 Linux driver series (390.12 Beta currently), I ran some fresh Linux OpenCL GPU compute benchmarks on a variety of AMD and NVIDIA graphics cards for those curious how the current performance stacks up.

For those that were excited over the months of ongoing work by SUSE to bring up an in-kernel boot splash system that could be better than Plymouth for at least some use-cases and was interesting many readers, unfortunately it's not panning out for mainline...

These days when Dave Airlie isn't busy managing the DRM subsystem or hacking on the RADV Vulkan driver, he's been spending a fair amount of time on some OpenGL improvements to the aging R600 Gallium3D driver. That's happened again and he's landed some more improvements just ahead of the imminent Mesa 18.0 feature freeze...

With the Linux 4.17 kernel (not the upcoming 4.16 cycle) there is likely to be added initial HDCP support to Intel's Direct Rendering Manager driver. Ahead of that this High-bandwidth Digital Content Protection support continues getting improved upon...

Beyond the Retpoline support already found in the mainline Linux kernel, developers are working on Retpoline Underflow support that would be used for Intel Skylake and Kabylake CPUs. RETPOLINE_UNDERFLOW protects against falling back to a potentially poisoned indirect branch predictor when a return buffer underflows and this additional protection is needed for Intel Skylake/Kabylake processors.
