With last week's release of the much anticipated Ubuntu 22.04 LTS, Canonical announced they would begin providing a real-time kernel flavor too for this Long Term Support release though that RT kernel is initially in beta form. Today they outlined more information on their real-time kernel beta and how to actually go about trying it out...

LLVM 14.0.1 released just earlier this month while already LLVM 14.0.2 is out today. LLVM normally sees just a single point release and traditionally happened mid-to-late in the development cycle ahead of LLVM's next major release. But now LLVM is moving to shipping point releases every two weeks...

Systemd lead developer Lennart Poettering is out with his first blog post since last September. Today he's relaying the power of the systemd-sysext component shipped as part of systemd for loading/merging "system extension" images on the system for manipulating the exposed /usr...

While Intel launched the Arc A-Series Mobile Graphics at the end of Q1, so far at least in major US markets no laptops with these graphics are currently available. As such it's hard to assess the current Linux driver support level and with no clear communication from Intel on the matter. Intel has been working on their upstream DG2/Alchemist support for a while but it looks like with the Linux 5.19 kernel this summer is what will likely be their base version requirement for the DG2/Alchemist-based Intel GPUs...

Back in 2020 file-system driver provider Paragon Software announced they wanted to upstream their NTFS driver into the Linux kernel. This driver was previously a proprietary, commercial offering from the company but given the state of NTFS these days they wanted to upstream this driver with full read/write support and other features not found within the existing NTFS driver. Finally last year after going through many rounds of review, the new driver was merged into Linux 5.15. Sadly, less than one year later, concerns have been raised that the driver is already effectively orphaned and not being maintained...

It looks like Linux 5.19 will have all the base preparations in place for Arm Scalable Matrix Extension (SME) support...

Originally attempted with Linux 5.18 were patches so /dev/urandom and /dev/random would behave exactly the same. That was dropped though due to not enough randomness at boot for some platforms like Arm 32-bit, Motorola m68k, Microblaze, Xtensa, and others. But then the change went in to opportunistically initialize /dev/random as a best-effort approach where it at least works nicely on x86/x86_64. The good news is that original unification effort may be re-visited in the future now that the original blocker issue has been addressed...

VMware has merged support for SVGAv3 into Mesa 22.2. SVGAv3 is the latest update to their virtual graphics device for allowing 3D guest virtual machine acceleration with VMware's virtualization products...

Last week AMD began shipping the much anticipated Ryzen 7 5800X3D as their first 3D V-Cache consumer CPU and their claims to be "the world's fastest PC gaming processor" in being able to outperform even the Core i9 12900K / 12900KS for Windows gaming. We weren't seeded by AMD for this launch, leading us to anticipate that it's not too good for Linux gaming / not their target market. But after the great success I've had with AMD Milan-X performance on Linux, I was very eager to try out this consumer CPU with the 3D-stacked L3 cache and ended up purchasing a 5800X3D. Indeed the Ryzen 7 5800X3D turned out to be disappointing for Linux gaming performance but the 5800X3D was very interesting for a range of other technical workloads and making me very excited for future Ryzen CPUs with 3D V-Cache.

For two years there has been interest and unmerged patches for allowing Linux's plethora of firmware blobs to be Zstd-compressed for helping to save disk space. Finally it looks like for Linux 5.19 that optional Zstd firmware compression support will be merged...

In addition to Ubuntu 22.04 switching back NVIDIA to using X11 by default rather than Wayland as a launch-day change, separately, there was another rather notable last minute change affecting 3D support for virtual machines... Those with Ubuntu 22.04 hosts and launching Ubuntu 22.04 desktop VMs will find 3D acceleration disabled by default...

The widely-used FFmpeg multimedia library has merged support for the JPEG-XL image format...

AMD's open-source Linux engineers on the CPU side of the house continue being quite busy with all sorts of new feature enablement work, which given their timing and other factors is almost all definitively for upcoming Zen 4. AMD this week sent out updated patches in getting "PerfMonV2" support in order that is updated performance monitoring abilities with upcoming processors...

In addition to CUPS back to seeing new feature development for this print server now being managed by OpenPrinting, CUPS founder Michael Sweet also continues being quite busy with working on PAPPL as his modern printer application framework effort...

While back in March Ubuntu 22.04 "Jammy Jellyfish" changed the default behavior for NVIDIA's driver to use Wayland inline with Intel and Radeon graphics having used the GNOME Wayland session rather than X.Org for the past few releases, this change was reverted at the last-minute. With a launch-day SRU, Ubuntu 22.04 LTS is defaulting to using the GNOME X.Org session rather than Wayland when running the proprietary NVIDIA driver...

With Mesa 22.1 having been branched and working its way towards release in early to mid May, it's a good time to deliver some fresh Linux gaming benchmarks on the latest GPU drivers. In this article are some reference benchmark results of various AMD Radeon graphics cards on Mesa 22.1-rc1 as of branching paired with Linux 5.17 and then benchmarked against NVIDIA's latest driver and various GeForce RTX GPUs.

Last year open-source developers called on Intel to open-source their "PSE" firmware. The Programmable Services Engine (PSE) introduced with Elkhart Lake is an Arm Cortex-M7 companion core responsible for various tasks and is programmed by a binary-only firmware module. While it started out as a proprietary, binary blob, the PSE firmware has now been open-sourced!..

Intel in cooperation with the Alliance for Open Media has done on a terrific job on the development of SVT-AV1 for open-source, high performance CPU-based AV1 video encoding. This morning marks the release of SVT-AV1 1.0...

While the Mesa 22.1 feature release will hopefully be out in about two weeks, out today is Mesa 22.0.2 as the newest point release for the current Mesa stable series. With this release slipping an extra week, there are even more bug-fixes than usual back-ported into this version...

NVIDIA by way of their GPU compute / CUDA Fortran interests and having acquired the PGI compiler company nearly a decade ago has been active contributors to the LLVM Fortran scene. NVIDIA spearheaded the work on the modern LLVM Fortran compiler support and worked with other vendors and the open-source ecosystem on the since-upstreamed FLANG compiler. NVIDIA had been maintaining a "fir-dev" downstream for their latest Fortran compiler patches while now moving forward they will be focused on upstream LLVM contributions...

One of the less talked about features with Ubuntu 22.04 LTS "Jammy Jellyfish" is Canonical offering up a "beta" of a real-time Linux kernel image for use with this long-term support release. In doing so, Canonical is expanding their aim for Ubuntu Linux within industrial and other use-cases demanding real-time needs...

Ubuntu 22.04 LTS "Jammy Jellyfish" is now available for download...

OpenBSD 7.1 is out this morning as the newest version of this popular, security-minded BSD operating system...

Longtime Linux users especially those that frequented Linux conferences/events in pre-COVID times are likely familiar with Dirk Hohndel. Dirk has a well known track record with Linux going back to the 90's, good friend and diving buddy with Linus Torvalds, and now somewhat surprisingly has moved on to promoting a blockchain effort...

At the end of last year you may recall the talked about Linux kernel patches for booting systems faster by allowing the parallel bring-up of secondary CPU cores. It's been a while since hearing much about that effort but seems to have hit a snag in that the code is running into problems on early Zen CPUs and older...
