Given the recent discussions over the default performance of the Linux scheduler, the Liquorix patches to the Linux kernel, and other recent forum discussions over different kernel configurations and flavors, here are some reference benchmarks looking at the performance of some of the kernel options available to Clear Linux users...

While more Linux distributions have begun packaging (and in the case of Fedora, potentially deploying by default) EarlyOOM as the out-of-memory monitoring daemon for trying to improve the Linux desktop's handling of low memory situations, systemd ultimately should be picking up its own out-of-memory daemon in the months ahead...

The recent work by longtime kernel developer Andy Lutomirski on improving Linux's random APIs and introducing a new "GRND_INSECURE" option is now queued into the random dev queue ahead of the Linux 5.6 cycle...

At the annual Consumer Electronics Show in Las Vegas there isn't too often "pure" Linux being showcased aside from the likes of Ubuntu occasionally running on demo machines or servers, the year Canonical was there with Ubuntu TV, and a number of other select mostly small instances where Linux is prominently featured. That's in part why I stopped regularly attending CES (as well as budgetary constraints due to ad-blockers...) but this year at CES there is a large floor showcase of the Linux Foundation's Automotive Grade Linux...

Following Fedora's plans to begin using EarlyOOM by default and other recent upstream discussions about Linux's relatively poor performance when it comes to the Linux desktop not handling memory pressure / low RAM situations well, Intel's Clear Linux looks like it will soon offer EarlyOOM as an option...

For those plagued by OpenGL corruption issues with the RadeonSI driver on Polaris GPUs like the Radeon RX 580, System DMA (SDMA) support is now being disabled as a workaround...

Stemming from the recent news in Fedora 32 potentially LTO'ing packages by default for better performance and not yet having checked on the Link-Time Optimization performance of the in-development GCC 10, here is a fresh look at the possible performance gains from making use of link-time optimizations for generating faster binaries. This round of testing was done on the AMD Ryzen Threadripper 3960X and is complementary to the recent Profile Guided Optimization benchmarks.

AMD has issued their first update to the open-source Radeon GPU Profiler since the v1.6 update last July that introduced initial RDNA/Navi support...

Wiring up an additional feature for Intel's IGC Linux network driver that is for their 2.5G Ethernet devices is allowing data to be sent up to 7% or so faster...

Similar to Fedora's move last year to compress RPMs with Zstd rather than XZ for much faster decompression speeds and a better compression ratio at the highest level, OpenMandriva has now enacted a similar change...

This weekend I posted some fresh benchmarks of the Liquorix kernel against upstream Linux 5.4 and found the gaming performance to be rather disappointing for that kernel flavor derived from the "Zen" patches and more. Fortunately, the Zen kernel patches now include a fix that should make their gaming performance more competitive...

Last week I reported on a possible workaround for helping AMD APUs with stability issues on recent Linux kernels. That behavior will now be the new temporary default in dealing with stability issues on Raven APUs...

A late change proposal for Fedora 32 would jump the shipped Mono package from version 5.20 to version 6.6...

It was just shy of a month ago in Mesa 20.0-devel code that RadeonSI enabled NIR by default to enjoy OpenGL 4.6 support and now already ahead of the Mesa 20.0 branching the previous TGSI code-path has been removed. TGSI has been the default intermediate representation of RadeonSI and other Gallium3D drivers but these days NIR has become the go-to IR for Mesa drivers...

Following AMD's keynote with announcing the Ryzen 4000 series + RX 5600 XT + Threadripper 3990X, Intel now has up their address from the 2020 Consumer Electronics Show (CES). Here are all the highlights from the perspective of a Linux user...

With Python 2 having reached end-of-life at the start of 2020, Ubuntu and Debian developers continue their work on removing Python 2 at least from the base OS. Work continues on transitioning packages to Python 3 or otherwise ultimately dropping unmaintained packages...

A new work-in-progress feature for systemd is "PathImages" though there is a suggestion this option be renamed to "MountPaths", but in any case is about allowing arbitrary images / block devices to be mounted at any path by systemd...

While there still is several weeks to go until the Linux 5.5 kernel reaches stable and that marking the start of the Linux 5.6 merge window, already from the work we've been tracking in the various "next" branches, this first full kernel cycle of 2020 is going to be a big one...

Shortly before Christmas were a couple open-source Nouveau driver patches volleyed by NVIDIA. Some of that work is now queuing in the Nouveau DRM tree ahead of the Linux 5.6 merge window...

While still a draft standard, support for the RISC-V "V" Vector Extension support for the Linux kernel is currently being prepared...

Linux 5.5 development has been picking up in recent days following Christmas week and New Year's but now more upstream developers returning to their keyboards in order to get this next kernel update buttoned up for its debut around month's end...

While Fedora 32 is already making it so CD / DVD install issues shouldn't block releases given most users are doing USB-based installations for the past number of years, Fedora is still trying to decrease the amount of space the install media takes up regardless of CD/DVD/USB media...

GNOME Shell 3.35.3 and Mutter 3.35.3 were released today as part of the next development step on the path towards GNOME 3.36 coming out in March...

When navigating the AMD.com driver downloads area the Radeon Software for Linux 19.30 driver is still referred to, which was released back on 5 November. That 19.30 driver series has been around for a while and we've been waiting for the 19.50 series driver to match their recent Windows driver update. It turns out there is a Radeon Software for Linux 19.50 driver that is public albeit not widely advertised...

Linux 5.5 as of this morning should have one less performance regression in tow if you are running on Debian/Ubuntu or otherwise having AppArmor enabled...

As you may recall a few days ago there was the information on the Linux kernel scheduler causing issues for Google Stadia game developers. The scheduler was to blame and in particular Linux's spinlocks. Linus Torvalds has now commented on the matter...

While New Year's festivities lightened the development activity this past week, KDE developers still managed to accomplish a fair amount this first week of January...

It's 2020 and GIMP remains one of the last holdouts for a major software application still relying upon the GTK2 tool-kit even with GTK4 potentially coming around the end of the calendar year. Fortunately, at least, the GIMP 2.99.x development releases on the path to the GTK3-based GIMP 3.0 should be starting up soon...

Arch Linux has been working the past several months on transitioning to Zstd-compressed packages in place of XZ compression for faster package installation. At the end of December that package compression scheme changed and the results are impressive...

The Liquorix kernel is the long-standing effort for providing a "better distro kernel" optimized for desktop/multimedia/gaming workloads. As it's been a while since last testing the Liquorix kernel spin of Linux, I recently carried out some tests of its Linux 5.4 based kernel compared to Ubuntu's generic mainline PPA images of Linux 5.4 as well as the low-latency kernel variety.

Last week I wrote about the AMD Secure Processor support for Linux 5.6 being queued as part of the cryptography subsystyem work with supporting the PSP / Secure Processor of Raven Ridge APUs. That AMD Secure Processor support is now rounded out with the Trusted Execution Environment (TEE) driver being queued for wiring into that subsystem...

Zink was one of the Mesa/Gallium3D innovations that saw mainline status in 2019 for offering OpenGL support atop Vulkan hardware drivers. While an interesting approach, so far only the dated OpenGL 2.1 support has been exposed but the Collabora-led effort is closing in on OpenGL 3.0 capabilities...

With Red Hat shifting their support to Wayland and expecting the X.Org Server to go into a hard maintenance mode quickly, in 2019 indeed it did...

Back in late 2018 when Linus Torvalds went on a sabbatical from kernel development to focus on his inter-personal skills, the kernel added a Code of Conduct. To date there hasn't been much transparency into the Code of Conduct committee that acts upon violations, but that is changing in 2020...

While complicated by New Year's festivities, Wine 5.0-RC4 was released today with just fifteen bug fixes for the week -- also a sign of the development cycle winding down for this annual Wine stable release...

For months there has been many different discussions over the Linux desktop's poor performance when under memory pressure / out-of-memory type situations. That has resulted in some upstream work so far like GNOME GLib's GMemoryMonitor as well as discussions by distribution vendors about what solutions they could enable today to help the low memory situations. Fedora 32 could begin shipping and using EarlyOOM by default to help in this area...

Hitting Mesa 20.0-devel a short time ago were a set of patches to the Radeon Gallium3D video code for fixing 10-bit HEVC video decode support...

Your choice of Linux distribution on a budget PC can mean the difference of ~14% performance overall. Here are benchmarks of Ubuntu, CentOS, Debian, EndeavourOS, Manjaro Linux, openSUSE Tumbleweed, Fedora Workstation, and Clear Linux on a $50 processor as we roll into 2020 with the newest Linux distribution releases.
