ARB_transform_feedback_overflow_query For Intel's Mesa Driver

Intel's Mesa driver is at OpenGL 4.5 compliance but there are many extensions still left to be implemented that haven't appeared in a formal OpenGL specification. One of those extensions now being implemented is ARB_transform_feedback_overflow_query.

Librecore: Aiming To Be A Better Libre Spin Of Coreboot

Librecore is a new project aiming to be a new Coreboot downstream with a focus remaining on providing fully-free system firmware. Separately, Minifree/Libreboot has been accused (and admitted by Leah Rowe) to not paying a vendor for a completed contract.

NVIDIA Linux OpenCL Performance vs. Radeon ROCm / AMDGPU-PRO

Earlier this week I posted some benchmarks of GPUOpen's new Radeon Open Compute ROCm OpenCL stack that premiered last month and they are working to make completely open-source. In those initial benchmarks I compared the ROCm 1.4 OpenCL performance to the existing AMDGPU-PRO OpenCL implementation on Linux. For those wondering how these two Radeon OpenCL stacks compare to NVIDIA, here are some fresh benchmarks.

Expanded Turbo Boost Max 3.0 Support Is Being Worked On For Linux

With the forthcoming Linux 4.10 kernel there is finally support for Turbo Boost Max 3.0 as featured in some newer Intel CPUs. But, unfortunately, the code in Linux 4.10 doesn't work for all TBM3-capable systems out there, but a new kernel patch is being worked on for Linux 4.11 or later to make it work with more hardware.

Fedora vs. Ubuntu vs. openSUSE vs. Clear Linux For Intel Steam Gaming Performance

With this week Clear Linux now being able to run Steam, I was excited to see how this performance-minded Linux distribution out of Intel's Open-Source Technology Center would compare to other more popular Linux distributions when it comes to Intel Linux gaming performance. Here are some benchmarks of this traditionally workstation/server-oriented Intel Linux distribution running some Steam Linux games.

Benchmarking Radeon Open Compute ROCm 1.4 OpenCL

Last month with AMD/GPUOpen's ROCm 1.4 release they delivered on OpenCL support, albeit for this initial release all of the code is not yet open-source. I tried out ROCm 1.4 with the currently supported GPUs to see how the OpenCL performance compares to just using the AMDGPU-PRO OpenCL implementation.

Here's How To Setup Clear Linux For Intel Steam Linux Gaming

A few weeks back we learned of Intel's Clear Linux distribution working towards Steam support. While Clear Linux is a performance-oriented workstation/server/cloud distribution, repeatedly in our tests it performs among the top Linux distributions even when it comes to Intel OpenGL Linux gaming, so being able to game with it isn't a far stretch with Steam support -- there is also Vulkan support now too.

Fedora 26 Planning For A Modular Server Preview

Fedora Linux has been pursuing a path of modularity whereby modules provide different software purpose/functionality and are integrated/tested at the module level and a unit of delivery itself. With the Fedora 26 release they are hoping to provide a Fedora Modular Server preview build.

Broadwell Vulkan Performance Also Up After Recent Mesa Git Work

Yesterday I published a number of OpenGL/Vulkan benchmarks from Mesa Git in Mesa Git Delivering Faster Intel Vulkan Performance, Closer To OpenGL Driver Speed. Those tests were with Skylake desktop graphics so for some follow-up reference tests I also fired up Mesa Git on an Intel Broadwell ultrabook.

Google Developers Experiment With Plumbing Dartlang Into LLVM

It's been a while since last hearing much excitement around Google's Dart programming language that's an alternative to JavaScript. This ECMA-approved language is now being used with IoT devices, can still be source-to-source compiled for JavaScript, and the latest is that the Google developers have been experimenting with wiring it into LLVM.
