Last week I posted benchmarks looking at seven years of Ubuntu Linux performance in re-testing the releases of Ubuntu 13.04 through Ubuntu 19.10 stable and even the latest Ubuntu 20.04 LTS daily development image. A question that came up was how much better that performance would have been without any CPU vulnerability mitigations in place for Ubuntu 20.04... Well, here's that answer...

Libre RISC-V, the project aiming to create an open-source accelerator that would run a Vulkan software renderer in being an "open-source GPU" aiming for just 25 FPS @ 720p or 5~6 GFLOPS, has managed to secure 300k EUR in grants for their work...

With the Wraith Prism heatsink fan included with many modern AMD Ryzen processors there is configurable RGB lighting, which unfortunately AMD hadn't publicly documented or offered a Linux utility for manipulating the RGBs under Linux. Fortunately, there is now a straight-forward solution for dealing with those Wraith Prism RGB LEDs thanks to the open-source and independent CM-RGB project...

With our various ending-2019 and end-of-2010s articles, the standout on the Linux performance front has certainly been Intel's Clear Linux in consistently delivering the leading Linux x86_64 performance throughout all of our testing on many different tests and hardware platforms. Here's a look back at some of the Clear Linux highlights...

Back in November was the first of several KDE Frameworks 6 developer sprints as plans begin to formulate for this evolutionary frameworks upgrade due out not until well after the Qt 6.0 tool-kit release. While Qt6 itself is still in flux, KDE Frameworks 6 efforts continue moving along by focusing on porting code away from deprecated KF5 functionality...

Here's a look back at the most popular news over the past decade on X.Org out of our one thousand plus articles on the topic during the 2010s. Even with Wayland taking off in recent years and effectively reaching parity to the X.Org Server for common use-cases, the X.Org Server has continued seeing new development especially in the areas of GLAMOR and XWayland. Sadly though we're ending the 2010s without a major stable release of the xorg-server since May 2018...

Going back a number of years has been various out-of-tree front-ends for GCC toying with the ability to compile Rust code with GCC while a new discussion has started up about the prospects of theoretically mainlining one of those efforts or otherwise developing a new GCC Rust front-end...

Recently a Phoronix reader inquired about seeing some fresh hard drive RAID benchmarks on the current kernel release and using Btrfs / EXT4 / XFS. While we don't often look at HDD RAID performance these days compared to speedier SSD testing, since the reader was a generous Phoronix Premium member I was happy to oblige to his test request. Here is a look at the Linux 5.4 HDD RAID performance per his request with Btrfs, EXT4, and XFS while using consumer HDDs and an AMD Ryzen APU setup that could work out for a NAS type low-power system for anyone else that may be interested.

For the Linux 5.5 kernel that's about half-way through its development phase we have been pointing out some rather significant performance regressions affecting both AMD EPYC and Intel Xeon servers but there are also regressions to be found with desktop class systems too...

Last month I wrote about AMD working on TEE driver support to load "trusted applications" onto the AMD Secure Processor under Linux. That work is now queued for introduction with Linux 5.6 and wired through for Raven Ridge APUs...

Last week I posted benchmarks looking at the performance of Intel's Clear Linux over the course of 2019 with roughly 7% better performance across dozens of benchmarks on the same system. But how does that compare to other Linux distributions with the same hardware? Here is a look in showing the performance for both Fedora and Ubuntu at the end of 2018 to the end of 2019.

Since this summer Intel open-source engineers have been working on adding ACPI Error Disconnect Recover (EDR) support to the Linux kernel and this week marks the eleventh revision to the kernel support for this new ACPI feature...

Early on in the Linux 5.5 cycle during the merge window we saw some wild swings in performance including some positive gains but also performance regressions. Given last weekend's Linux 5.5-rc3 release having merged some scheduler fixes and other fallout from early on in Linux 5.5, I was curious to see if those regressions have been addressed... Sadly, they are not...

Mesa's LLVMpipe Gallium3D driver has long been about running OpenGL on GPUs as a software fallback / debug path but as of this morning in Mesa 20.0-devel there is now the experimental ability of having OpenCL support making use of OpenCL "Clover" with NIR for CPU-based execution...

Following Richard Stallman being ousted from the Free Software Foundation, the FSF was said to be re-evaluating its relationship with the GNU while R.M.S. said no radical changes are expected. Now a group of GNU maintainers have laid out some of their desires for improving the interactions between the GNU and FSF...

One of the few still maintained Linux distributions derived from Gentoo is Calculate Linux, which saw a new release today in preparing for the new year...

As we enter 2020, Debian remains one of the oldest Linux distributions out there and over the 2010s continued advancing quite well for being volunteer-led and competing with the corporate heavyweights like Ubuntu, Red Hat, and SUSE. Debian in the 2010s found itself being used as the basis for Valve's SteamOS, continuing to be integral to the success of Ubuntu, it ultimately decided to make use of systemd, there were various desktop changes, and multiple successful releases of Debian GNU/Linux to celebrate...

One of the new open-source compiler IR advancements of 2019 has been the Google/Tensorflow MLIR as the Multi-Level Intermediate Representation designed for machine learning models/frameworks. With Google's "IREE" project, MLIR can be accelerated by Vulkan and thus allowing machine learning via this high-performance graphics/compute API...

The 2010s were great for the long-standing Wine project that allows Windows games/applications to run near effortlessly on Linux, macOS, and similar platforms. CodeWeavers' investments into Wine continue turning out very well for the continued success and now with Valve's Steam Play built upon the Wine-based Proton, more Linux gamers are happier than ever...

With Mesa 20.0 expected to ship the "Iris" Gallium3D driver as the default Intel OpenGL Linux driver for Broadwell hardware and newer, I've been ramping up my testing of this open-source driver in recent weeks. For adding to the various generations of CPUs tested, here are some numbers of the latest code when using the UHD Graphics 630 off the high-end Core i9 9900KS processor...

Most KDE users are probably happy with the current state of the Plasma desktop and the state of the KDE applications. There's certainly less bugs in recent releases, KWin and the overall desktop is in better standing (though still improvements to be made such as showcased by the likes of KWin low-latency) with reliable Wayland support, and most would probably agree that the work out of this open-source project matured rather well in recent years with their focus on enhancing usability and other areas...

First of all, Merry Christmas for those of you celebrating today or Happy Holidays regardless...

While the GNU Hurd microkernel is still woefully behind in hardware support and hasn't even seen a new release in three years, at least a lot of the other GNU projects experienced a great decade -- especially with the likes of the GNU Compiler Collection, GNU Octave, GRUB, and other components critical to modern Linux systems...

While the open-source Radeon Linux graphics stack has made some remarkable improvements this year not only from AMD but also the likes of Valve, unfortunately not as much can be said about the state of the open-source NVIDIA (Nouveau) driver. The Nouveau Linux graphics driver remains much slower than the proprietary driver, the hardware with the best support is several generations old, and due to the lack of signed firmware images there still isn't yet any open-source 3D for the Turing GPUs that have been shipping for months. But there may be hope in 2020.

Western Digital has been contributing a lot more to the Linux kernel in recent years from RISC-V architecture bits to storage enhancements. The most recent code they have been working on in recent weeks is a brand new Linux file-system...

Not only has LLVM's Clang compiler proven to become a viable alternative to C/C++ and is now widely used by many different vendors for building production software and nearly at parity for performance to GCC, but the LLVM compiler infrastructure has proven to be a huge success. Beyond Apple as one of the original stakeholders, LLVM is also used by multiple software projects within Intel, AMD is making extensive use of it for their graphics compiler and other purposes, and many other companies leveraging the LLVM projects for various often innovative purposes -- Microsoft is even using it within select projects...

While not attracting as much interest as Linux in the cloud, AI, and other growing markets, the BSDs have seen their share of adoption in many of these areas too as well as the likes of powering some of today's video game consoles. FreeBSD is also well known for powering much of the networking infrastructure of Netflix and other large enterprises. The BSDs advanced a lot from hardware support to new security features and other capabilities this decade setting them on a good trajectory as we get into the 2020s...

After many delays, and seemingly as a Christmas miracle, Eric S Raymond now believes his Reposurgeon utility is officially ready to convert GCC's SVN repository over to Git...

Announced last month was the Athlon 3000G as a ~$49 processor based on Zen and featuring two cores / four threads and Vega 3 graphics. This 35 Watt TDP processor has finally begun appearing at more Internet retailers in stock last week and I was able to pick up one of these budget CPUs for $55 USD. Here are benchmarks of the Athlon 3000G on Ubuntu Linux compared to other low-end and older processors.
