It didn't land for Linux 5.11 but it looks like Linux 5.12 could end up supporting Intel's "HDR Backlight Interface" for helping newer Intel laptops with their backlight controls where they don't comply with VESA specifications but rather catering to Intel's proprietary interface...
While Linux 5.11-rc1 was just released yesterday, we have already been closely monitoring the new features of Linux 5.11 as well as carrying out early benchmarks. One area looking quite good so far are the Intel graphics performance and features with Linux 5.11, or more specifically Gen9 and newer while the latest Xe Graphics are obviously the most interesting from a benchmarking perspective.
Bootlin working under contract for an unnamed NAS vendor has been working to update the Large Page Support for 32-bit ARM and ultimately coming up with an upstream-friendly way to be able to support more than 16TB of storage on 32-bit ARM devices...
Of all the new Linux 5.11 features and all the enablement work Intel has already completed for Xeon "Sapphire Rapids" hardware, one big feature not yet mainlined is the Advanced Matrix Extensions (AMX) support...
The Linux 5.11 merge window has been open the past two weeks following the debut of Linux 5.10 but is set to close today. A lot of new features and exciting improvements were merged for Linux 5.11 although it is somewhat of a bumpy ride at the moment but should be buttoned up and ready for its stable release come February.
Back in 2010 was a change to disable run-time power management of PCI devices by default and leaving it up to user-space to in turn override it if desired. Now as we gear up for 2021, some upstream kernel developers are wondering about that original decision and possibly changing the default behavior to yield better out-of-the-box power savings with modern systems...
The HAMMER2 file-system that has been used by default on DragonFlyBSD for some time has lacked multi-volumes support compared to its former HAMMER1 file-system. But as of this weekend in the latest Git development code, HAMMER2 now has initial support for multiple volumes...
While being released one day late due to Christmas, Wine 6.0-RC4 is out. This is the latest weekly test candidate of the forthcoming Wine 6.0 as the annual stable release due out in January for this leading software to run Windows programs/games on Linux, macOS, and the BSDs...
One of the pleasant kernel surprises in 2020 was Paragon Software looking to upstream their previously commercial NTFS driver. This driver offers read-write support and more advanced capabilities than the current read-focused NTFS driver presently in the mainline kernel and better off than the other FUSE-based driver. This driver hasn't been mainlined yet but Paragon published new patches on Christmas...
LibreOffice has various "AVMedia" back-ends for supporting the playback of audio and video within the open-source office suite with GStreamer and other platform-specific options. LibreOffice also supported a VLC back-end for audio/video playback but after years of that code being experimental and not maintained, it's now been eliminated...
Adding to the open-source Christmas excitement this year was the release of GIMP 2.99.4 that puts this image editor one step closer to the long-awaited GIMP 3.0...
After a half-decade working toward it, Ruby 3.0 was released on Christmas Day with much greater performance and other features for this high-level general purpose programming language...
It's not the Grinch in 2020 that stole Christmas, but the Schedutil CPU frequency scaling governor on the in-development Linux 5.11 kernel that is thrashing performance for AMD Zen 2 and newer. Distributions like Ubuntu, Fedora, and Manjaro are beginning to use CPUFreq Schedutil by default on newer kernels and thus leading to a very bad initial/out-of-the-box experience with the current behavior on the early Linux 5.11 code.
It's been a turbulent year and 2020 is certainly ending interesting in the Linux/open-source space... If it wasn't odd enough seeing Sony providing a new official Linux driver for their PlayStation 5 DualSense controller for ending out the year, there is also a new Linux port to the Nintendo 64 game console... Yes, a brand new port to the game console that launched more than two decades ago...
Linux 5.10 as a Long-Term Support (LTS) kernel has been off to a rocky start after an immediate point release due to a RAID issue, some reporting AMDGPU problems, and also a staggering Btrfs performance regression hitting some users...
For those looking to get involved with the Fedora project in manner besides the likes of coding and documentation, a Fedora Zine is being established and are looking for creative submissions...
It's looking like Wasmer 1.0 will be released early in the new year as the open-source WebAssembly run-time for desktops or to run WASM code anywhere as a "universal runtime" in contexts outside of the web browser...
Well here is a pleasant Christmas surprise... Sony has published a new "hid-playstation" Linux kernel driver for bringing up the PlayStation 5 DualSense controller and will also be used for supporting other PlayStation hardware on Linux...
To those celebrating any year-end holidays, Happy Holidays / Merry Christmas. It's been a hell of a year and 2021 will hopefully be better. In any event even if not celebrating any end of year holidays or other events, there still is daily Phoronix content to come...
A few days ago I noted nice AMD EPYC performance improvements with PostgreSQL when running on Linux 5.11 compared to prior kernels. I've confirmed that for even more AMD EPYC servers now that the PostgreSQL uplift is there, but other workloads are unfortunately regressing for both Ryzen and EPYC. Here's the start of an exciting Christmas benchmarking adventure looking at this change with Linux 5.11.....
The past several days FreeBSD has been working to complete its migration from their development being done with Subversion to instead using the Git distributed revision control system as used by most other open-source projects...
A few days ago there was a glibc commit mentioning Intel "LAM" and now the updated Intel documentation sheds more light on this forthcoming processor feature...
The out-of-tree Reiser4 file-system has now been ported to the week-old Linux 5.10 kernel code-base. This also comes days ahead of the one year anniversary since the "Version 5" announcement...
Linux 5.11's Kconfig build configuration updates are bringing some long overdue improvements to its "Qconf" Qt toolkit user interface option for configuring Linux kernel builds...
Last week the Linux 5.11 power management updates were merged while on Tuesday some additional new material was merged, primarily around Intel's P-State CPU frequency scaling governor when running with the "Schedutil" governor that makes use of the kernel's scheduler utilization data...
Earlier this month we were a bit surprised to see Windows 10 performing close to Ubuntu 20.10 on the AMD Ryzen 9 5900X. With prior AMD Ryzen (and Intel Core) desktop CPUs we normally are used to seeing Ubuntu Linux exhibit healthy performance advantages over Windows 10 in most workloads. But with Zen 3 the Windows vs. Linux performance is much closer and thus led us to also running Windows 10 vs. Ubuntu benchmarks on the higher-end Ryzen 9 5950X to reproduce the earlier findings.
Fedora 34 is shaping up to be another exciting Fedora Linux release on the feature front. Among the material to look forward to in this spring 2021 Linux distribution release is routing all audio through PipeWire by default, enabling systemd-oomd by default, an independent XWayland package, and more. The latest proposal involves making use of DNF/RPM copy-on-write support atop Btrfs with Fedora 34...
Just in time for the upcoming AMD Ryzen 5000 series mobile processors, it's looking like the S2idle support is finally coming together on Linux for increased power savings...
Landing in Mesa 21.0 on Tuesday was support for OpenGL tessellation shaders (ARB_tessellation_shader) with the Zink Gallium3D code implementing generic OpenGL support atop Vulkan...
Merged into the Linux kernel back in 2015 was the TraceFS file-system to better address Linux tracing use-cases that previously were handled atop DebugFS. Now LibTraceFS has reached version 1.0 as the user-space library around TraceFS after being spun out of Trace-CMD earlier this year...
Xfce 4.16 managed to ship in 2020 as one of the original goals for this release after the much delayed Xfce 4.14 series. Xfce 4.16 comes with many incremental improvements to this GTK3 desktop environment...
Microsoft continues pushing new code into Mesa 21.0 as its efforts around Mesa continue to ramp up principally around GPU acceleration within Windows Subsystem for Linux (WSL) as well as allowing the likes of OpenGL and OpenCL to function under Windows 10 in the absence of native GL/CL drivers by using Mesa to translate the APIs for consumption by Direct3D 12 drivers...
At the end of November systemd 247 released with the new Out-of-Memory Daemon (systemd-oomd) and for the Fedora 34 release next year that will likely be enabled by default for all spins...
The Linux hardware monitoring "k10temp" driver is dropping support for reporting CPU voltage and current information for AMD Zen-based processors over lack of documentation for being able to properly support the functionality...
As we have shown with prior AMD Ryzen and EPYC processors, the Linux distribution generally offering the fastest out-of-the-box performance is Intel's Clear Linux platform. Given there aren't many other distributions as aggressively optimizing their default package set and engaging in features like AutoFDO, PGO, and various out-of-tree patches in the name of modern Intel x86_64 Linux performance -- and in turn, AMD performance benefits as well -- Clear Linux really shines with modern hardware. Testing of the latest Clear Linux with a Ryzen 9 5900X continues to delivering promising performance compared to the likes of Fedora, openSUSE, Manjaro, Debian, and Ubuntu.
If you miss flying this holiday season due to the pandemic, you can at least experience it virtually by flying your own aircraft with the open-source, cross-platform FlightGear flight simulator software...
Ahead of the upcoming freezes set to begin around Debian 11 "Bullseye", the Debian developers working on KDE packaging have been working to get all the latest components updated in time...
