Redox OS, the open-source Rust-written operating system led by developer Jeremy Soller, has been drafting some exciting plans for the rest of this year and moving into 2024.

Google formally unveiled Android 14 today in New York City at its Made By Google event. With that, Google has also published the Android 14 Open-Source Project (AOSP).

GNOME developer Christian Hergert recently demonstrated how Linux terminal emulators have the potential of running much faster. At the time it didn't sound like he would pursue the matter further but more recently he's begun working on folding some performance improvements into GNOME's VTE for a faster terminal experience.

The newest open-source project hosted by the Linux Foundation is OpenPubkey, which is a collaboration with Docker and BastionZero and will be available for Docker container signing with zero-trust passwordless authentication.

Vulkan 1.3.266 was published a few days ago with a handful of fixes and two new extensions. One of those extensions, VK_NV_low_latency2 is quite interesting.

When it comes to the BSD operating systems, DragonFlyBSD's HAMMER2 is one of the most interesting innovations. HAMMER2 supports online deduplication, clustering, multiple mountable file-system roots, snapshots, compression, encryption, extensive checksumming, and other features. Over the past decade it's evolved quite nicely and in recent days has seen further enhancements.

Currently when hibernating a Linux system LZO compression is used for preserving the memory contents while a new patch series posted today by Qualcomm allow for changing out the compression API used and makes LZ4 a new option during Linux hibernation.

A nasty vulnerability has been made public today concerning Glibc's dynamic loader that can lead to full root privileges being obtained by local users. This affects Linux distributions of the past two years with the likes of Ubuntu 22.04 LTS, 23.04, Fedora 38, and others vulnerable to this local privilege escalation issue.

The biggest hindrance for using Intel Arc Graphics for Linux gaming has been the lack of Vulkan sparse support as needed for running many newer Windows DirectX 12 games atop Valve's Steam Play with Proton using VKD3D-Proton. Intel recently did implement Vulkan sparse support for ANV in Mesa 23.3 but it only works with their yet-to-be-upstreamed and still-experimental Xe kernel driver. But now Intel Linux graphics driver engineers have managed to pull off a solution for getting the sparse resources supported while using the existing i915 kernel DRM driver.

It was a decade ago that a security researcher commented on X.Org Server security being even "worse than it looks" and that the GLX code for example was "80,000 lines of sheer terror" and hundreds of bugs being uncovered throughout the codebase. In 2023 new X.Org security vulnerabilities continue to be uncovered, two of which were made public today and date back to X11R2 code from the year 1988.

Today the review embargo lifts on the first AMD-powered Framework laptop. There's one of the AMD Framework laptops in the lab for Linux testing and benchmarking but unfortunately no review for launch day due to being held up by a BIOS regression and thus unable to properly utilize accelerated graphics until a new BIOS revision is made available in the coming days.

As written about last month, AMD Linux engineers have been working on PMF Linux driver support for a "Smart PC Solutions Builder". The AMD Smart PC Solutions Builder feature is intended to provide OEMs with more control over system power/performance policies. It looks like systems making use of this feature are already to the marketplace or imminent with AMD having already landed the PMF firmware.

Adding to the list of notable features coming with Mesa 23.3 later this quarter is enabling delta color compression (DCC) for multi-sample anti-aliasing (MSAA) images on AMD RDNA3 (GFX11) graphics processors.

Checking for the presence of Intel virtualization (VMX) support and it being enabled can be easily achieved by looking at the flags in /proc/cpuinfo. But to this point AMD virtualization (SVM) has always been shown to user-space via /proc/cpuinfo even when the BIOS/platform has disabled SVM functionality. Finally for Linux 6.7 this oversight is being corrected.

Similar to Embree 4.0 adding Intel graphics acceleration earlier this year via SYCL, Intel's OpenVKL library that is also part of their oneAPI rendering toolkit has now added SYCL graphics acceleration with OpenVKL 2.0.

The past several Linux kernel cycles has seen Loongson engineers working on implementing more kernel features for LoongArch, the MIPS-derived and RISC-V-inspired architecture out of China for domestic PCs. The performance of LoongArch CPUs so far still aren't competitive to x86_64 or Arm hardware but at least slowly are becoming more practical with more features being wired up. The latest milestone is the Kernel-based Virtual Machine (KVM) virtualization support appearing ready ahead of Linux 6.7.

A newly-opened merge request for GNOME's Mutter compositor adds hardware acceleration for the NVIDIA proprietary driver for secondary GPUs such as in the case of hybrid systems and other setups with multiple monitors whereby the NVIDIA GPU with proprietary driver is powering some of those outputs.
