Ubuntu Linux ISOs for RISC-V 64-bit to date have just been the server/CLI version without any desktop environment pre-seeded. But with next week's Ubuntu 26.10 release, there will now be Ubuntu 26.10 RISC-V desktop ISOs for both Ubuntu proper and a Xubuntu minimal ISO.

Python 3.15 is out today as the newest annual feature release for the Python programming language.

Last week I ran benchmarks of the new AMD PerfOpt feature being introduced in Linux 7.4. In those PerfOpt benchmarks on current-gen AMD Ryzen AI APUs/SoCs the AI performance improved as much as 18~23%. Several Phoronix readers expressed interest in seeing how prior-gen AMD Ryzen hardware benefited or not from PerfOpt, so here are some additional benchmarks.

From a performance and enthusiast perspective, what I personally find most disappointing and puzzling with the imminent release of Ubuntu 26.10 comes down to its default compiler version.

For those making increased use of Linux's Zswap as a compressed RAM cache for swap pages amid these times of sky high RAM prices, a new patch series was posted providing some incremental performance gains for Zswap by batching the writeback I/O.

When booting the Linux kernel using UEFI SecureBoot, the kernel is put in the lockdown mode to restrict the ability to modify the running kernel image or leaking data from kernel memory. Kernel lockdown mode can also be manually enabled by the user/administrator. Among the limitations imposed in Linux's lockdown mode is no hibernation support. But that soon may be relieved with new patches proposed.

Over the past few months NVIDIA has been developing Boro as a new AI-assisted kernel development CLI written in Rust and focused on local AI for enhancing efficiency for kernel development.

AMD on Thursday sent out a final pull request of their feature work aiming to be submitted for the upcoming Linux 7.4 merge window. This round of "few last odds and ends" is mostly about landing some bug fixes but of which there are a few worth mentioning.

For those making use of Qualcomm Snapdragon X laptops on Linux, one of the features coming to the MSM DRM kernel driver is static HDR support for DisplayPort outputs and eDP panels.

The latest proposal for the upstream Linux kernel is introducing infrastructure for AI agent resources. Initially these agent resources would be for a skill so AI agents can automatically add a "Fixes: " tag on relevant patches for noting the first problematic Git commit automatically that a patch fixes.

There is yet another feature to get excited about for this quarter's Mesa 26.3 release. Months in the making, the Valve-contributed VK_AMD_anti_lag support for the Radeon RADV driver was merged today for benefiting AMD Linux gamers as a nice improvement over the former implementation.

The EXT4 file-system today deprecated its journaled mode of the "data=journal" mount option. Following its deprecation, this mode is planned for removal in the year 2028.

System76 today released COSMIC Epoch 1.10 as the newest incremental update to this Rust-based desktop developed in-step with their Pop!_OS Linux distribution.

Those trying to access the Ubuntu website, ISO downloads, and similar Ubuntu resources today are finding the site inoperable amid what's now confirmed as an ongoing distributed denial of service attack.

While Ubuntu 26.10 is not a Long-Term Support (LTS) release and thus will see limited enterprise deployments compared to Ubuntu 26.04 LTS, for those not after that long-term deployment support and preferring to live more on the leading-edge, Ubuntu 26.10 is delivering some nice performance gains on current 5th Gen AMD EPYC "Turin" hardware.

The curiosity into secretive semiconductor startup Rosaic Labs builds. Earlier this year it was noted that Intel was providing Rosaic Labs with access to its Atom technology with RTL code. There have also been rather mysterious x86 additions not from Intel or AMD (or Zhaoxin / Hygon) that given the timing may pertain to Rosaic Labs. News today is that Rosaic recently hired a long-time, Linux x86 developer veteran.

NVIDIA engineer John Hubbard and Red Hat's Danilo Krummrich presented at this week's LPC2026 conference in Prague on the open-source and upstream Nova driver stack that continues forming as a Rust-based open-source NVIDIA Linux kernel driver.

Linux developers are once again considering the removal of the Linux x32 ABI.

Sashiko that was built by Google engineers for agentic review of the Linux kernel code changes and powered by Google's AI models continues proving very valuable to kernel developers. In less than one year since they launched Sashiko for agentic AI code review, their results are quite fascinating.

For those interested in the SpacemiT K3 as one of the few RVA23 RISC-V SoCs readily available so far and in the likes of the K3 Pico-ITX system, more improvements for its upstream kernel support are coming in Linux 7.4.
