Now with the CPUFreq fix landing this week in Linux Git, the mainline Linux 5.11 kernel in its near final state is looking in very good shape for AMD Zen 2/3 hardware from Ryzen laptops and desktops through EPYC servers. The Linux 5.11 development kernel was regressed for the better part of the past two months but now that the frequency invariance regression is addressed, not only is the regression gone but generally is performing much better compared to prior kernel versions.

Linux 5.11 stable is expected to be released on Sunday barring any second thoughts by Linus Torvalds that could lead to an eighth weekly release candidate that would in turn push the official release back by one week. In any case, Linux 5.11 will be formally out soon and it's an exciting one on the feature front...

With Linux 5.11 there is open-source Nouveau KMS support for Ampere GPUs -- just kernel mode-setting without any form of 3D acceleration. The actual hardware acceleration requires more work and also NVIDIA to release the necessary signed firmware binaries. With Linux 5.12 there still is no 3D acceleration but a big set of patches was merged as a step in that direction...

OBS Studio, the cross-platform open-source solution for live streaming and screen recording, has landed the last major piece of its effort to natively support Wayland...

For as rough of a year as 2020 was, one of the many open-source accomplishments was Sony taking up "official" maintenance of their HID driver and ahead of Christmas to much surprise they published an official PlayStation 5 DualSense open-source controller driver for Linux. That PS5 controller driver is now set to be introduced with the imminent Linux 5.12 merge window...

Among Intel's many open-source software accomplishments for 2020 was introducing OSPray Studio as part of oneAPI. OSPray Studio builds atop the existing OSPray ray-tracing engine and inter-connected oneAPI Rendering Toolkit components to offer an open-source scene graph application for interactive visualizations and ray-tracing based rendering. The newest OSPray Studio is now available...

It was just yesterday we were talking about Zink achieving OpenGL 4.3 support and wondering if OpenGL 4.4 or potentially even 4.5 could be buttoned up in time for Mesa 21.1... Well, as of a few minutes ago Zink now is advertising OpenGL 4.5 support for this graphics API layer built atop Vulkan...

With this spring marking two years already since Intel introduced the 2nd Gen Xeon Scalable "Cascade Lake" processors plus with Ice Lake Xeon processors being on the horizon, here is a look at how the flagship Xeon Platinum 8280 2P performance has evolved atop open-source Linux during that duration. The benchmarks today are looking at the performance of Ubuntu 19.04 for that of roughly the shape the Linux performance/optimizations were at launch and then the performance today if moving to the in-development Ubuntu 21.04 and also shifting to the latest Linux 5.11 kernel and GCC 11 code compiler.

It looks like thanks to AMD's increasing sales and continuing successes in the enterprise space with more HPC wins and the like, AMD is hiring more Linux engineers. AMD currently has several interesting job openings on the Linux front...

Just in time for the expected Linux 5.11 stable release on Sunday, the AMD frequency invariance performance regression I've been noting and writing about since Christmas day has been resolved with the previously covered fix having been merged today...

The official release of FreeBSD 13.0 is coming up in March, while already from our preliminary tests of the newly minted FreeBSD 13.0 BETA1, the benchmark results are extremely tantalizing compared to FreeBSD 12.2... Ultimately the performance should be much more competitive now compared to Linux (at least on Intel x86_64) and other operating systems with the big FreeBSD 13 release.

While GRUB 2.06 was aiming for release in 2020, having to deal with the BootHole security issue among other challenges last year ended up delaying that release. Fortunately, it looks like this long awaited GRUB feature update should be out this year and there has been increased cooperation between upstream GRUB developers and distribution vendors...

Announced nearly three years ago by Intel was the ACRN reference hypervisor framework intended for IoT/embedded use-cases with real-time capabilities and safety-critical computing. More of the kernel bits to this "Big Little Hypervisor for IoT Development" are set to see mainline with the imminent Linux 5.12 kernel cycle...

While there has been LibreOffice Online as a collaborative, web-based version of LibreOffice making use of the HTML5 Canvas for its UI, there hasn't been much activity there recently outside of the Collabora Online commercial variant.

While Linspire went dark for several years, under its current ownership by PC/OpenSystems they have been trying to reinvigorate the desktop distribution the past few years. Linspire 10 represents the latest work for the Ubuntu-based platform...

Going back to last summer there have been patches for getting OpenGL 4.6 with the Zink GL on Vulkan implementation but were considered experimental and not for immediate upstreaming. In the months since and especially after Mike Blumenkrantz was hired by Valve, the upstreaming effort kicked into higher gear. Now with Mesa 21.1, we are up to OpenGL 4.3...

Going back about two years there has been work on properly supporting Wine on POWER 64-bit (PPC64). Now past the Wine 6.0 stable release, it looks like that work that work is finally beginning to land. In conjunction with Hangover to handle the cross-architecture aspect, the hope is to eventually allow Windows x86 programs to work on libre POWER systems or at the very least with native Winelib support to help in porting open-source Windows software to IBM POWER / OpenPOWER...

Valve and their partners at CodeWeavers have put out a release candidate for Proton 5.13-6 as the latest version of their Wine-based software for running Windows games on Linux via Steam Play...

RADV is a Vulkan driver for AMD GPUs that is part of the Mesa project and installed on most Linux distros out of the box. Our goal is to deliver a stable and performant driver to Linux gamers, and recently we've made our own shader compiler called ACO. To create the best possible experience, we'd like to take it a step further and ask our users for some testing and feedback.

SYCL as the single-source C++-based programming model for heterogeneous parallel programming is now revised to the SYCL 2020 specification released today by The Khronos Group...

While it was a sad blow when PC-BSD/TrueOS stopped pursuing its desktop ambitions as what was arguably the leading BSD desktop operating system out there with a nice end-user experience, since then we have seen efforts like MidnightBSD, GhostBSD, and others fill the avoid with continuing to enhance the out-of-the-box BSD desktop system. A new entrant that is quite interesting is helloSystem that aims to be a "macOS of BSDs" for a polished desktop experience...

Last month was the delightful news that Ubuntu 21.04 is aiming to use Wayland by default for non-NVIDIA systems on the GNOME desktop rather than the X.Org session. While there is two months to go until the Ubuntu 21.04 release, there still is more work ahead in making that shift a reality...

Exfatprogs 1.1 have been released as the open-source, user-space utilities around the Linux/Android exFAT file-system support maintained by Samsung...

While so far only the NVIDIA proprietary driver on Linux supports the Vulkan ray-tracing extensions, eventually we will see support for these new Vulkan extensions with the AMD Vulkan drivers for the Radeon RX 6000 series and newer. There has also been work by Intel in preparing for Vulkan ray-tracing with Xe HPG. For when the time comes to test those implementations, there is finally one good, open-source, automated Vulkan RT benchmark so far...

More than a decade ago Intel was very excited about MIDs as "Mobile Internet Devices" with their early Menlow and Moorestown platforms. Intel's MID plays ultimately were unsuccessful in the long-term and the MID functionality ultimately evolved into smartphones and tablets. In 2021, the Intel MID support is being gutted from the Linux kernel...

While AMD has been crushing it when it comes to Linux performance and generally delivering good launch-day support, the one area many Linux/open-source advocates have been eager and hopeful to see change is around Coreboot support and ideally open-source firmware support such as by re-opening AGESA. Both inside and outside of AMD there continues being work in this direction...

The BeOS-inspired Haiku open-source operating system has continued pushing forward in 2021. The range of their work so far is quite diverse from finally landing SD/MMC driver support to at the same time being a bit more forward-looking and already working on 5-level paging support to handle terabytes of system RAM...
