For those curious how Ubuntu 17.04 is shaping up, considering this week was the "beta" release for participating flavors, I decided to take a fresh Ubuntu 17.04 x86_64 daily ISO and see how its performance compares to Ubuntu 17.10, Clear Linux 13600, Antergos 17.2, and openSUSE Tumbleweed.

Last year there was a Google Summer of Code student working on a library to implement double-precision operations (FP64) in pure GLSL 1.30 as a benefit to older GPUs not having native FP64 capabilities. While that work didn't materialize as a solution in 2017 for those wanting "soft" ARB_gpu_shader_fp64 for being able to potentially expose OpenGL 4.0 on more R600g era GPUs, the work is ongoing...

Several years back we wrote about Ultra Kernel Samepage Merging (UKSM) for data de-duplication within the Linux kernel for transparently scanning all application memory and de-duping it where possible. While the original developer is no longer active, a new developer has been maintaining the work and continues to support it on the latest Linux kernel releases...

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...

A few days ago I posted some results of surprise performance improvements for a Radeon RX 470 when testing the DRM-Next code queued for Linux 4.11. I've now tested that kernel on more systems and can confirm at least benefits more widespread for RADV's Vulkan performance.

When posting last week our Windows 10 vs. Ubuntu Radeon benchmarks and Windows vs. Linux NVIDIA Pascal benchmarks and then the Windows vs. Linux relative performance analysis, as usual, it didn't take long for some to argue that the Linux gaming performance is actually faster but "Unity 7 is slower" and the similar FUD that is usually waged whenever looking at cross-platform performance.

Last December we wrote about work being done on fuzzing OpenGL shaders leading to wild differences with the work being done at the Imperial College London. While they were testing other drivers on different operating systems, they have now fired up tests of Mesa...

Chances are if you are using a NVIDIA GeForce graphics card and planning to game on Linux you are using NVIDIA's official Linux driver, but in case you are trying to use the free software Nouveau driver stack, I tried running Feral's recent HITMAN game release with this open-source NVIDIA driver...

A mix of Qt5, Vulkan, Android on AArch64, and a NVIDIA Shield TV with Tegra X1 SoC sounds like a fun weekend for those wanting to experiment with the latest Qt tool-kit possibilities in development...

Arnd Bergmann has submitted the big batch of ARM hardware changes for the Linux 4.11 kernel merge window...

With the addition of over two thousand lines of code, GStreamer's video-convert code within gst-plugins-base is now properly multi-threaded...

This week marks the 17.01.0 final release of the Linux Embedded Development Environment (LEDE). They also presented at this week's Linux Foundation Embedded Linux Conference about their project that's a fork of OpenWRT and aims for router/embedded use-cases...

The TTY/serial patches were mailed in earlier this week by Greg KH for the Linux 4.11 kernel merge window. Normally this isn't a pull request with much interest from us as it's generally not too interesting, but this time around it introduces a new bus...

The Kernel-based Virtual Machine (KVM) changes have arrived for the Linux 4.11 kernel and there is a lot of them with over 200 commits and the introduction of new features for many of the supported architectures...

David Airlie submitted the main DRM driver updates for the Linux 4.11 kernel, but Linus Torvalds isn't happy about the code quality of a new addition and is considering not accepting the DRM changes for this next kernel release...

Ubuntu derivatives opting to do so have issued their 17.04 "Zesty Zapus" Beta 1 releases tonight...

Serious Sam VR: The First Encounter has been put into public beta today by Croteam for those interested in Linux VR gaming...

While hearing "ASPM" may still scare some of you from the Linux kernel power management woes of a few years ago, ASPM PCI-E L1 PM substate support is coming to Linux 4.11 to hopefully help with power savings for idle PCI Express devices...

There was some work years ago for supporting Intel's own INTEL_performance_query OpenGL extension it was dropped in January for a rework and now is back in Mesa 17.1-devel...

Last week Feral Interactive released the much anticipated Linux port of HITMAN, which debuted for Windows last year. Now that there's benchmark support for HITMAN on Linux, I have been running a number of tests for this game that's powered by the Glacier Engine and making use of OpenGL for rendering on Linux. In this article are our initial AMD Radeon performance figures making use of the RadeonSI Gallium3D driver compared to NVIDIA's driver and the assortment of GeForce results published yesterday.

With Valve having published a binary-only RADV Radeon Vulkan driver build for their beta of SteamVR on Linux, I did some poking out of curiosity to see the differences to the mainline RADV driver in Mesa. Out of curiosity I also did a comparison to see how the Vulkan capabilities compare to the proprietary AMDGPU-PRO Vulkan driver...
