Made public on Monday was CVE-2021-35465 as a new security vulnerability affecting various Arm products. For unmitigated (ARMv8-M) hardware, Arm has posted a series of GCC compiler patches for working around the issue...

Announced back in April of 2020 was Micron's HSE as an open-source storage engine optimized for solid-state drives and persistent memory. After quickly crossing the v1.0 milestone and working its way up to HSE 1.9 at the end of last year, there hasn't been any updates since. Fortunately, the project is still alive and HSE 2.0 is on the way...

One of the areas where AMD's long-standing "PRO" OpenGL driver has generally held an advantage over RadeonSI Gallium3D has been around workstation software but that has been changing...

One year ago to the day Intel announced OSPray Studio as a scene graph application for rendering glTF assets and other 3D models. OSPray Studio is built off their OSPray ray-tracing engine that they've been working on for years. These Intel efforts are all part of their oneAPI initiative and today happens to mark a shiny new feature release...

Last month I wrote about the proposed reflink support for Wine that would provide significant space savings for those having multiple Windows games/applications on Linux installed where Wine and derivatives like Crossover and Steam Play (Proton) generally maintain a separate "prefix" per software installation. Fortunately, that reflink support continues to be worked on for Wine where it can lead to savings up to several hundred megabytes per Wine prefix...

GTK 4.4 is out as the latest stable update to the GTK4 open-source toolkit...

Zink as an OpenGL-over-Vulkan API implementation living within Mesa merged its sub-allocator code that could deliver 10x the performance for some games. Plus it also landed OpenGL compatibility context support for getting more games working now with this open-source GL-on-VLK solution. Given the progress made in Mesa Git over the past week, here are some fresh benchmarks now for how the performance stands across various games and benchmarks.

Going on three years now there have been proposed patches for allowing per-client GPU engine statistics for being able to show on a per-game/application level how many resources across 3D/blitting/video engines are being consumed. The patches continue to be revised but sadly will be missing out on the imminent Linux 5.15 kernel merge window...

While Habana Labs has been known for their open-source and upstream Linux kernel driver for their AI training/inference accelerators with that code they had been working on as a start-up even before being acquired by Intel, it's continued to cause friction that they rely in user-space on closed-source components like their compiler. That in turn is again causing problems for changes that the Habana Labs kernel driver planned to land with the upcoming Linux 5.15 cycle...

Running Linux on the Apple M1 with various out-of-tree patches is now capable of booting to a GNOME desktop albeit lacking any OpenGL/graphics acceleration...

Since the start of July we've seen Intel beginning Linux support patches for their DG2 graphics card that is now known by the "Alchemist" codename. There's been several rounds of DG2 patches since they started publicly pushing out the code -- including some notable work like DisplayPort 2.0 bring-up -- while sent out this Sunday is another important piece of the puzzle: getting the device memory (the dedicated vRAM) actually working with the open-source driver...

While it was busy on the hardware side of the house with Intel talking up all of their forthcoming hardware, Intel's open-source software engineers remain very busy working not only to enable their next-generation hardware but other open-source efforts they've invested in like the iNet wireless daemon...

Red Hat's Hans de Goede continues doing a commendable job improving the Linux support for various laptops with key improvements. One of the latest efforts by this longtime kernel developer has been about getting DisplayPort over USB Type-C connections working for more Intel hardware...

While Intel is normally very punctual in providing support for major new CPU features under Linux and often landing them well in advance of general hardware availability, their work around Control-flow Enforcement Technology (CET) has taken a long longer than normal and is still going through new rounds of code review to get accepted into the mainline Linux kernel...

Due to the growing threat posed by file-less malware attacks where malware code is executed from anonymous executable memory pages that aren't backed by data on the file-system, the "NAX" Linux security module has been seeing work recently for helping to protect against such scenarios...

Earlier this week Amazon introduced Intel Xeon Scalable 3rd Gen "Ice Lake" powered EC2 cloud instances and marks their first x86-based sixth-generation offerings that follow their "M6g" Graviton2 instances launched last year. Curious about the "M6i" Ice Lake performance with AWS, here are a number of benchmarks looking at the performance and value of the new M6i instances compared to former Intel M5 instances as well as Amazon's own M6g Graviton2 instances.

The W3C has been working on the "Open Screen Protocol" as part of their Second Screen Working Group. This effort has been about having a web standard so web pages can drive secondary screens to display web content. Unfortunately, the plans are currently being complicated by a number of software patents issued to Apple...

Intel this week hosted a virtual Architecture Day where they talked up their latest efforts from Alder Lake and Sapphire Rapids to their next-generation discrete graphics capabilities as well as other new offerings around IPUs and more. Here are the highlights from Intel Architecture Day 2021 and with a particular focus from our Linux angle.

Many will recall DFI motherboards from close to two decades ago for their wildly colored "LANParty" motherboards but in recent years the company has been focusing on IoT and industrial hardware where, of course, Linux has much relevance. DFI and Canonical today announced an AMD-powered Ubuntu-loaded "industrial Pi" single board computer...

LibreOffice 7.2 Community is out today as the newest version of this widely-used, open-source, cross-platform office suite...

While Ubuntu normally ships with the very latest GNOME desktop version issued just before release time, with Ubuntu 21.04 they stuck to GNOME 3.38 rather than punting early to GNOME 40. In the Ubuntu 21.10 development packages they since migrated to GNOME 40 but now it looks like they will be sticking to that and not pulling ahead to the near-final GNOME 41...

While not making it for last week's SDL 2.0.16 release, merged on Wednesday to the SDL2 development code is an "SDL_GeometryRender" interface that stems from feature requests going back nearly a decade for this graphics API independent triangle rendering API...
