GNU Linux-Libre 4.10: GPU Drivers Remain The Most Frequent Offenders

The GNU Linux-libre 4.10 kernel was released last weekend just after the official Linux 4.10 kernel release while I hadn't noticed the de-blobbed kernel release until today. The Linux-libre folks continue to criticize the open-source GPU DRM drivers as being offenders for using binary blob firmware/microcode.

Trying The SteamVR Beta On Linux Feels More Like An Early Alpha

This past week Valve brought SteamVR on Linux into public beta. With watching the constant hype around VR on Windows, I was quite excited to finally give VR a try with having lined up an HTC Vive for testing and currently Oculus or others not offering current Linux support. I was thinking that I would have some large GPU/driver comparisons and such completed this weekend, but once actually setting up the hardware and software, I realized that wasn't going to be feasible in such short time. So for those interested in the Linux VR space, here are some of my first impressions and why I would consider the current SteamVR more like an alpha release than beta, just yet another struggle Linux gamers face, and another obstacle to overcome if Linux is to be a more serious competitor to Windows in the gaming space.

A Soft Implementation Of ARB_gpu_shader_fp64 Is Slowly Being Tackled For Mesa

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.

UKSM Is Still Around For Data Deduplication Of The Linux Kernel

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 While the original developer is no longer active, a new developer has been maintaining the work and continues to support it on the latest Linux kernel releases.

Wayland's Weston 2.0 Compositor Released

Wayland 1.13 was released earlier this week but the adjoining Weston compositor update didn't happen at the same time due to some last minute changes needing more time to test, but this Friday, Weston 2.0 is now shipping.

Fresh RadeonSI Mesa Git Gaming Benchmarks On 7 Linux Desktops

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.

Fuzzing Mesa Drivers Begin To Uncover Bugs

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.

Trying Nouveau With HITMAN On Linux Doesn't Get Too Far

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.
