Benchmarks Of OpenMandriva's AMD Zen Optimized Linux Distribution Against Ubuntu, openSUSE, Clear Linux

Released this week was OpenMandriva Lx 4.0 as the latest major release for this Linux distribution of Mandriva/Mandrake heritage and continues on the interesting trend of innovations. In addition to continuing to use the LLVM Clang compiler by default rather than GCC, among other changes that position it more uniquely than many other Linux distributions out there, their 4.0 release has a "znver1" spin that is optimized for AMD Ryzen/Threadripper/EPYC processors. Here are benchmarks comparing not only OpenMandriva 4.0's x86-64 and Znver1 options but also how that performance compares to the likes of Ubuntu 19.04, openSUSE Tumbleweed, and Intel's Clear Linux.

PowerCap/RAPL Code To Support Icelake Desktop / X / Xeon D With Linux 5.3

While as of Linux 5.2 the support for Intel's Icelake CPUs appear production ready with all of the bits in place from new IDs to the much enhanced "Gen 11" graphics, there are a few stragglers of items to land with the upcoming Linux 5.3 merge window though could be back-ported to current series. Fortunately, we haven't found anything major to be missing.

HAMMER vs. HAMMER2 Benchmarks On DragonFlyBSD 5.6

With the newly released DragonFlyBSD 5.6 there are improvements to its original HAMMER2 file-system to the extent that it's now selected by its installer as the default file-system choice for new installations. Curious how the performance now compares between HAMMER and HAMMER2, here are some initial benchmarks on an NVMe solid-state drive using DragonFlyBSD 5.6.0.

Ubuntu 19.10 To Drop 32-bit x86 Packages

Ubuntu and their downstream flavors all stopped shipping x86 32-bit images and now for the 19.10 cycle they have decided to stop their i386 support entirely. Beginning with Ubuntu 19.10, the archive/packages will not be built for x86 32-bit.

AMDVLK Still Hasn't Yet Adopted FreeSync Support

While the AMDGPU kernel driver has shipped with the long-awaited FreeSync support since the Linux 5.0 release earlier this year and was quickly wired up for the RadeonSI Gallium3D OpenGL driver in Mesa 19.0 while the recent Mesa 19.1 update brought FreeSync for the RADV Vulkan driver, AMDVLK as AMD's official open-source Vulkan driver isn't yet supporting this variable rate refresh technology.

AMD Posts 459 Linux Kernel Patches Providing Navi Support - 412k+ Lines Of Code

As we've been expecting, AMD's open-source developers today posted their set of patches enabling Navi (10) support within their AMDGPU DRM kernel driver. Bringing up the Navi support in kernel-space are 459 patches amounting to more than four-hundred thousand lines of code, not counting the work done to LLVM as part of their shader compiler back-end or the yet-to-be-published OpenGL/Vulkan driver patches.

Linux 5.3 Could Finally See FSGSBASE - Performance Improvements Back To Ivybridge

The FSGSBASE instruction set has been present on Intel processors going back to Ivy Bridge processors and while there have been Linux kernel patches for this feature going on for years, it looks like with the Linux 5.3 kernel cycle is this support for merging. Making us eager for this support is the prospect of better performance, especially for context switching workloads that already have been suffering as a result of recent CPU mitigations.

Developers Devising Plan To Ship Newer NVIDIA Drivers On Ubuntu Stable Releases

Currently NVIDIA's packaged drivers on Ubuntu can get a bit stale on Ubuntu stable releases since they aren't updated in-step with the latest driver releases. But a new stable release update (SRU) policy/exception similar to the Firefox approach is being made for Ubuntu so that new releases will end up working their way into currently supported Ubuntu series.

KDE Frameworks 5.60 Bringing More Baloo Optimizations

Making KDE's Baloo file indexing/searching framework really efficient appears to be a never-ending task. Baloo is already much less bloated recently than it's been hungry for resources in the past and with KDE Frameworks 5.60 will be slightly more fit.

Lightworks 14.6 Remains A Closed-Up Blob, But At Least The Linux Support Continues

It was nearly a decade ago the high-end, commercial video software editing solution Lightworks announced they would be going open-source but to this day that milestone has yet to be materialized. Lightworks though does continue advancing with their v14.6 release on the horizon and at least their added Linux support continues to be expanded upon.

It's Becoming Possible To Soft-Disable Intel ME 12 On Newer Motherboards

The past few years there's been the me_cleaner software for disabling and stripping parts of Intel's Management Engine for soft-disabling the notorious bit on modern Intel boards. ME_Cleaner has been making much progress and now there is work pending for being able to disable the newer Management Engine 12 found on more recent Intel motherboards.
