DragonFlyBSD Now Runs On The Threadripper 2990WX, Developer Shocked At Performance

Last week I carried out some tests of BSD vs. Linux on the new 32-core / 64-thread Threadripper 2990WX. I tested FreeBSD 11, FreeBSD 12, and TrueOS -- those benchmarks will be published in the next few days. I tried DragonFlyBSD, but at the time it wouldn't boot with this AMD HEDT processor. But now the latest DragonFlyBSD development kernel can handle the 2990WX and the lead DragonFly developer calls this new processor "a real beast" and is stunned by its performance potential.

Collabora's Mesa EGLDevice Work To Better Support Multiple GPUs

As covered earlier this month, Emil Velikov at Collabora has been working on EGLDevice support for Mesa. These EGL extensions originally developed by NVIDIA are being pursued by Mesa developers for better dealing with the enumeration and querying of multiple GPUs on a system.

NVIDIA 396.54 Linux Driver Released To Fix A OpenGL/Vulkan Performance Bug

One day after announcing the GeForce RTX 2070/2080 series, NVIDIA has released a new Linux driver. But it's not a major new driver branch at this time (that's presumably coming closer to the 20 September launch date) with the Turing GPU support, but is a point release delivering a practical bug fix.

Three New Security Advisories Hit X.Org's X11 Library

It's been a while since last having any big security bulletins for the X.Org Server even though some of the code-base dates back decades and security researchers have said the security is even worse than it looks and numerous advisories have come up in recent years. But it's not because X11 is bug-free as today three more security bulletins were made public affecting libX11.

Debian Developers Discuss Process For Salvaging Packages

While Debian has tens of thousands of packages in its archive and users often tend to cite the size of a package archive as one of the useful metrics for evaluating a OS/distribution or package manager's potential, not all packages are maintained the same. In acknowledging that not all packages are maintained to the same standard and some ultimately slip through the cracks, Debian developers are discussing a salvaging process.

Libratbag + Piper Allow For Great Logitech Gaming Mouse Support On Linux

While Roccat previously backed their devices on Linux that is the case no more and what is left for the time being are various community/third-party applications for supporting gaming mice/keyboard configuration under Linux from Logitech to Razer and various other lesser known brands of gaming peripherals (Razer will hopefully change this, at least). One of the most promising efforts right now for unifying mouse configuration on Linux is libratbag and its GTK3 Piper interface. Ratbag and Piper have evolved into a very competent open-source project for configuring Logitech mice on the Linux desktop.

Mesa 18.2 Is Releasing Soon With Many OpenGL / Vulkan Driver Improvements

Mesa 18.2.0 is expected to be released in the days ahead as the latest quarterly feature release to this collection of open-source user-space graphics driver components. As has been the case each quarter for particularly the past few years, these timed quarterly releases are quite feature-packed.

Freespire 4.0 Released, The Linux Distribution That Originated As "Lindows"

Earlier this year development on Linspire/Freespire was restarted for this Linux distribution that dates back to 2001 when it launched as "Lindows" before having to be renamed due to a trademark dispute with Microsoft. Back in January, PC/OpenSystems who is now developing the distribution, the Freespire 3.0 release debuted while today Freespire 4.0 is available.

The Impact Of The CPU Frequency Scaling Governor On AMD Threadripper 2990WX Linux Performance

One of many test requests we have received concerning the AMD Threadripper 2 Linux performance was to look at the impact of the different CPU frequency scaling governors, particularly for the 32-core / 64-thread Ryzen Threadripper 2990WX. Here are those CPUFreq governor benchmarks for those interested in squeezing slightly better performance out of your HEDT system by changing how aggressively or not the system is shifting power states to higher frequencies.

The Next Challenge For Fwupd / LVFS Is Supporting NVMe SSD Firmware Updates

With UEFI BIOS updating now working well with the Fwupd firmware updating utility and Linux Vendor Firmware Service (LVFS) for distributing these UEFI update capsules, Richard Hughes at Red Hat is next focusing on NVMe solid-state drives for being able to ship firmware updates under Linux.

A Fresh Look At The NVIDIA vs. Radeon Linux Performance & Perf-Per-Watt For August 2018

With NVIDIA expected to announce the Turing-based GeForce RTX 2080 series today as part of their Gamescom press conference, here is a fresh look at the current NVIDIA Linux OpenGL/Vulkan performance with several Pascal graphics cards compared to AMD Polaris and Vega offerings. Additionally, with these latest Linux drivers, the current look at the performance-per-Watt.

The Performance Hit For A Xeon-Backed Ubuntu Linux VM With L1TF / Foreshadow Patches

Last week L1 Terminal Fault (a.k.a. L1TF and Foreshadow) was made public as the latest set of speculative execution vulnerabilities affecting Intel processors. This Meltdown-like issue was met by same-day Linux kernel patches for mitigating the problem and does introduce another performance penalty but in this case is at least only limited to virtual machines. Last week I posted some initial L1TF-mitigated KVM-based VM benchmark results using a Core i7 CPU but the results for sharing today are using a much more powerful dual Xeon server.

Linux 4.19 Had A Very Exciting First Week Of New Features

A Look At The Windows vs. Linux Scaling Performance Up To 64 Threads With The AMD 2990WX

This past week we looked at the Windows 10 vs. Linux performance for AMD's just-launched Ryzen Threadripper 2990WX and given the interest from that then ran some Windows Server benchmarks to see if the performance of this 64-thread CPU would be more competitive to Linux. From those Windows vs. Linux tests there has been much speculation that the performance disparity is due to Windows scheduler being less optimized for high core/thread count processors and its NUMA awareness being less vetted than the Linux kernel. For getting a better idea, here are benchmarks of Windows Server 2019 preview versus Ubuntu Linux when testing varying thread/core counts for the AMD Threadripper 2990WX.

Benchmarks Of Btrfs RAID On Four Samsung 970 EVO NVMe SSDs

With the MSI MEG X399 CREATION that we received as part of the launch package for the Threadripper 2950X and Threadripper 2990WX it includes the XPANDER-AERO that provides 4-way M.2 NVMe SSD slots on a PCI Express x16 card. The XPANDER-AERO is actively cooled and could be passed off as a small form factor graphics card upon a very cursory examination. With this card I've been running tests on four Samsung 970 EVO NVMe SSDs in RAID to offer stellar Linux I/O performance. Here are some initial benchmarks using Btrfs.

Intel Has Quietly Been Working On A New Gallium3D Driver Being Called "Iris"

After resisting Gallium3D for the past decade with a preference on continuing to maintain their "i965" Mesa classic driver and all they've invested into its compiler stack and more, it seems times are changing as the open-source Intel team has been starting up development of a modern Gallium3D driver.
