Following the release of OpenXR 1.0, Collabora has announced the release of Xrdesktop, which was funded by Valve...

Complementary to yesterday's Radeon RX 5700 / RX 5700 XT Linux Gaming Performance With AMDGPU 5.3 + Mesa 19.2-devel, here are some benchmarks showing how the RadeonSI OpenGL performance has evolved for the Radeon RX 5700 and RX 5700 XT since they launched three weeks ago for this open-source OpenGL Linux stack...

Unity 2019.2 rolled out today as the latest quarterly feature update for this very popular cross-platform game engine...

Arch-based Linux distribution Manjaro has issued their newest testing update with some controversial changes...

The open-source MoltenVK project that offers Vulkan API support for Apple devices on iOS and macOS is out with a new release for mapping Vulkan atop Apple's Metal graphics/compute stack...

Last week I wrote about the GCC 10 compiler picking up a new scheduler model and cost tables for AMD Zen 2 CPUs to build off the initial "znver2" microarchitecture target from last year. Fortunately, those Znver2-specific improvements have now been back-ported to the GCC 9 compiler branch so it will see user systems with not as long of a wait until GCC 10 stable...

Valve's interesting ACO shader compiler alternative to AMDGPU LLVM currently for the RADV Vulkan driver as well as for RadeonSI OpenGL in the future now can handle vertex shaders...

In continuation of the article last week how the RISC-V Linux kernel support has been maturing and various missing gaps filled in, another feature just arrived in patch form: support for KVM virtualization...

In addition to new patches coming out on Monday for addressing power management with AMD's unreleased "Arcturus" GPU, a set of Mesa patches were merged for adding RadeonSI Gallium3D driver support...

While LLVM 9.0 was branched nearly two weeks ago and it was anticipated that the release candidate would immediately follow, only yesterday did 9.0-RC1 materialize...

Earlier this month AMD's Linux driver team sent out their initial open-source patches bringing up the "Arcturus" GPU as a new Vega family product. Today a second batch of patches adding in two thousand more lines of Linux kernel driver code were sent out...

NVIDIA's Unix/Linux graphics driver team has kicked off a new week by introducing the 430.40 long-lived driver release...

Now that the flow of initial Navi fixes and optimizations has settled down for both the AMDGPU DRM kernel driver and the Mesa RADV/RadeonSI user-space driver components, here is a look at AMD Radeon RX 5700 and RX 5700 XT graphics card performance on Ubuntu Linux at the end of July, now three weeks after these 7nm graphics cards first shipped.

It still remains to be seen if Purism will be able to ship the Librem 5 Linux smartphone this quarter as is their current revised target, but at least today they are publishing the finalized specifications for the phone's hardware...

In addition to the release of OpenXR 1.0 for kicking off SIGGRAPH 2019 week, The Khronos Group has released Vulkan 1.1.117 as a fairly notable update to this high-performance graphics API...

Back during the Game Developers Conference was the release of the OpenXR provisional specification by The Khronos Group while today for SIGGRAPH they have formally announced OpenXR 1.0...

Two weeks after AMDVLK received initial Navi 10 support, another release of this official open-source AMD Radeon Vulkan Linux driver is now available. With this 2019.Q3.3 release there is performance optimizations for Navi as well as some new extensions...

TurboSched is a new Linux kernel scheduler that's been in development by IBM for maximizing use of turbo frequencies for the longest possible periods of time. Rather than this scheduler trying to balance the load across all available CPU cores, it tries to keep the priority tasks on a select group of cores while aiming to keep the other cores idle in order to allow for the power allowance to be used by those few turbo-capable cores with the high priority work...

Thanks to funding from Arm Holdings and Crossbar, the PyPy folks working on their speedy Python JIT implementation have extended it to support 64-bit ARM (AArch64) with compelling performance results...

AMD's GPUOpen development team has kicked off the new week by releasing Radeon GPU Profiler 1.6, their open-source and cross-platform GPU profiling and analysis utility. With Radeon GPU Profiler 1.6 comes support for gathering insights on AMD Radeon RX 5000 "Navi" graphics processors...
