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.

Nouveau Gets Patches For HDMI Stereoscopic 3D Output

Nouveau continues advancing on the display front: beyond getting DP MST and atomic mode-setting support in the Linux 4.10 kernel, there are now patches available for wiring this open-source NVIDIA Linux driver up to supporting stereoscopic 3D output via HDMI.

KDE Support For Flatpak Portals Progressing

While GNOME / Red Hat developers have been leading the Flatpak app sandboxing initiative, KDE developers are making progress too with embracing Flatpak as a more convenient and secure way of securely packaging Linux desktop apps.

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.

RadeonSI Nearly Clearing The OpenGL 4.5 Conformance Test Suite

While RadeonSI in Mesa Git exposes OpenGL 4.5, it hasn't yet formally passed the OpenGL 4.5 Conformance Test Suite (CTS) for certifying the OpenGL driver. But now it looks like this open-source Radeon Linux graphics driver has about all OpenGL CTS failures addressed.

Intel's Mesa Driver Set To Flip On OpenGL 4.5 For Haswell

It was just two weeks ago that Intel's Mesa driver finally crossed the threshold with Haswell for supporting OpenGL 4.0 and then last week OpenGL 4.2 was crossed for this older generation of Intel graphics hardware. Now, it looks like OpenGL 4.5 will be enabled for Haswell with the i965 Mesa driver.

A Look At Where The P-State Linux Driver Does Bad Against CPUFreq, Clear Linux Tests

I'm still running more benchmarks in investigating the Core i5 7600K Linux performance and with even its graphics performance being slower than Skylake. I fired up Clear Linux on this Kaby Lake system this weekend and it's indeed faster than Ubuntu, though there still is some sort of fundamental issue at play with these new CPUs on Linux. But what is clear is that there are cases where the P-State CPU frequency scaling driver does perform very poorly over the mature, generic CPUFreq scaling driver.

AMD HSA IL / BRIG Front-End Still Hoping To Get Into GCC 7

For many months now there's been work on an AMD HSA IL front-end for GCC with supporting the BRIG binary form of the Heterogeneous System Architecture Intermediate Language (HSA IL). It's getting late into GCC 7 development and onwards to its final development stage while this new front-end has yet to be merged.
