AMD AOCC 1.2 Code Compiler Offers Some Performance Benefits For EPYC

Last month AMD released the AOCC 1.2 compiler for Zen systems. This updated version of their branched LLVM/Clang compiler with extra patches/optimizations for Zen CPUs was re-based to the LLVM/Clang 6.0 code-base while also adding in experimental FLANG support for Fortran compilation and various other unlisted changes to their "znver1" patch-set. Here's a look at how the performance compares with AOCC 1.2 to LLVM Clang 6.0 and GCC 7/8 C/C++ compilers.

ARM Mali 400/450 "Lima" DRM Driver Steps Closer To Mainline

When it comes to open-source ARM Mali graphics driver efforts there has been the Panfrost driver targeting the Mali T700 series that has occupied much of the limelight recently, but there has been a separate effort still working on open-source driver support for the older 400/450 series.

Raven Ridge With The Ryzen 5 2400G On Mesa 18.2 + Linux 4.17 Is Finally Stable

Depending upon the motherboard and other factors, the Raven Ridge Linux support has been a bit of a mess since its February launch. Fortunately, with time various Linux driver fixes have landed for improving the stability and performance of these APUs with Zen CPU cores and Vega graphics. During my recent testing of the AMD Ryzen 5 2400G, it was completely stable and running fine with the newest open-source driver code but the Ryzen 3 2200G was still a stability nightmare.

AMD Will Continue Maintaining Multiple Compute Stacks For Linux

With the great shape that ROCm has been getting into recently for open-source Radeon GPU compute support on Linux including advancing OpenCL support, one might have rightfully assumed that was going to be their centralized compute stack moving forward. It turns out that their PAL-based compute stack will continue to be maintained too.

VMware 13.3 X.Org Driver Brings DRI3 With Latest Mesa, X.Org Server 1.20 Support

Usually X.Org DDX driver releases aren't too notable these days with most of the open-source Linux graphics innovations happening elsewhere in the stack, but for those using the VMware graphics virtualization support available through their different virtualization products, the xf86-video-vmware update out today is on the heavier side.
