Following AMD completing their HDMI 2.1 implementation for the open-source AMDGPU Linux driver after beginning with HDMI FRL patches earlier in the year, Intel's open-source driver developers are following in their footsteps.

EXT4 with the upcoming Linux 7.4 kernel looks like it will introduce opt-in support for IOmap buffered I/O in replacing the file-system's buffer_head usage with IOmap.

Linus Torvalds has made available what is hopefully the final release candidate before Linux 7.3 is ideally minted next Sunday.

Linux creator Linus Torvalds has been known to use AI to help with kernel debugging and outside of the kernel tree has also done some vibe coding with Google's Antigravity. He has previously said he views AI as a useful tool. It turns out he's even now using Claude Code for working on new Linux kernel features.

AMD TLBI Erratum #1718 was worked around in CPU microcode for addressing a defect in certain Zen CPUs where the Translation Lookaside Buffer Invalidate Instruction use could lead to to stale translation entries. But for those on affected AMD CPUs and not running the updated microcode, a kernel workaround is being introduced with today's Linux 7.3-rc7 kernel and to be back-ported to prior kernel versions.

Microsoft is contributing a new kernel driver for the upcoming Linux 7.4 cycle. Queued up into the IOMMU subsystem's "-next" branch is a new para-virtualized IOMMU driver for benefiting Linux guest VMs running on Microsoft's Hyper-V virtualization platform.

The Linux kernel build for RISC-V doesn't currently make use of the CPU ISA's Vector extension. but leveraging it with compiler auto vectorization is showing the ability to provide nice performance results for enhancing RISC-V Linux performance.

Drgn is the open-source project out of Meta developing a very versatile debugger with the intent being a debugger focused on programmability with it striving to "make scripting as natural as possible so that debugging feels like coding." Drgn 0.3 released this weekend with the latest round of improvements.

Sent out today as part of this week's input subsystem fixes are device ID additions to the XPad driver for enabling two more gaming controllers to work nicely under Linux.

As some interesting food for thought and weekend forum discussions, this week at the Linux Plumbers Conference in Prague, Qualcomm engineer Khem Raj questioned the relevance of Linux Long Term Support (LTS) distributions in the era of generative AI with the constantly heavy patch flow and bug reports. Khem Raj argued the benefits of rolling release distributions in the GenAI era and the benefits it provides staying up-to-date with mainline.

Many x86 platform driver improvements have been queuing ahead of the upcoming Linux 7.4 merge window to offer a variety of laptop and gaming handheld device improvements with this next kernel version.

A while back we covered KNOD as an experimental solution for in-kernel network offloading to AMD GPUs. The open-source KNOD project allows leveraging GPUs to handle packet processing in a very performant and energy efficient manner without needing any specialized hardware. KNOD has continued and a development update was shared this week at the Linux Plumbers Conference in Prague.

Ahead of the Linux 7.3-rc7 kernel due for release on Sunday, this week's batch of networking fixes were submitted and merged. The vast networking subsystem of wired and wireless drivers plus the various other networking features continues to see a lot of activity due to AI-driven bug reports and patches.

KDE Plasma 6.8 is gearing up for its official debut next week in coinciding with the 30th anniversary since the KDE project began.

SQLite 3.54 released today for this wildly popular embedded SQL database engine used by countless applications and other software. With SQLite 3.54, support for Microsoft Windows XP and older is finally removed.

CodeWeavers working with Valve today released Proton 11.0-2e as their downstream of Wine that powers Steam Play for enjoying Windows games on Linux.

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.
