Wine 9.17 is out today as quite an exciting update for this open-source software that allows Windows games and applications to run on Linux systems and other platforms...

Intel has submitted more kernel graphics driver changes for the upcoming Linux 6.12 cycle. Following the pull requests to DRM-Next last week to enable Lunar Lake Xe2 graphics and Battlemage by default, some more lingering feature patches were merged today. Most exciting with this last round of patches before Linux 6.12? Intel graphics card fan speed reporting is finally wired up for their Linux driver...

One of the security changes with AMD Zen 5 processors that I haven't seen AMD publicly mention at least not prominently is that the new cores are not vulnerable to Speculative Return Stack Overflow (SRSO). Unlike Zen 4 and prior, under Linux I noticed that Zen 5 is no longer affected by the SRSO "INCEPTION" vulnerability. But of course there does remain other CPU security mitigations in place carried over from Zen 4. For those wondering about the mitigation costs or if it's worthwhile running Zen 5 with the "mitigations=off" insane mode, here are some benchmarks.

Back in 2022 were a set of patches that allowed compiling the ARM64 Linux kernel from Apple macOS hosts. The intent was for developers just wanting to do some build/smoke testing from under an Apple Silicon device running macOS to see at least any kernel changes are successfully compiling on macOS with its LLVM/Clang-based toolchain. An updated form of those patches were posted today for review...

With this week's announcement of the Intel Core Ultra 200V Series "Lunar Lake" processors, I've been very eager to try out the Meteor Lake successor for Linux testing. As sadly is usually the case, for delivering Linux support details and performance benchmarks around launch-time I'm typically left buying a laptop retail for Linux testing. In this case after seeing the Lunar Lake laptops announced this week and their availability, I ended up settling on the ASUS Zenbook S 14 (UX5406SA-S14.U71TB) for the initial Core Ultra 200V series Linux review...

We're very close to the finish line for the mainline Linux kernel being able to enable real-time "PREEMPT_RT" kernel support...

Sent out today were the DRM fixes for 6.11-rc7 ahead of the Linux 6.11-rc7 kernel being released on Sunday. As usual most of the changes revolve around the AMDGPU and Intel i915/Xe drivers plus random fixes to the smaller drivers. There is one change though with the AMD Radeon graphics driver side worth highlighting to address a performance regression affecting recent kernels...

It's taken until now to add FreeBSD to the X.Org Continuous Integration (CI) automated testing so that all proposed changes to the X.Org Server can now be build-tested on FreeBSD rather than just Linux...

FEX 2409 has been released for this open-source project that's known for allowing x86_64 Linux binaries -- including both games and applications -- to run rather well on AArch64. It's also been working on enabling x86_64 programs on RISC-V but there due to architectural differences it's more of a challenge than with ARM...

Additionally, quantifying the performance impact of using the ARM64 64K page size kernel as an alternative to the default 4K page size.

Last year to much excitement in our community was the new AMD project announcement of openSIL as an open-source CPU silicon initialization project that is an advancement for open-source firmware and to eventually replace AMD's AGESA across both client and server processors. This week an exciting new update on AMD OpenSIL was shared and that they are still on-track for having it production-ready next year...

Ah the memories of old AGP graphics cards... But it's largely just that these days: distant memories. For anyone by chance still running an Accelerated Graphics Port (AGP) graphics card in production, FreeBSD is looking at deprecating its generic AGP driver and then potentially removing it in FreeBSD 15.0...

With Linux 6.12 the Lunar Lake and Battlemage graphics are being enabled by default for out-of-the-box support with Intel's next-gen Xe2 graphics. Over in user-space the Intel OpenGL and Vulkan driver code has also begun enabling Xe2 graphics by default for use when running on Linux 6.12+. In Mesa besides no longer being hidden by the force probe option, a warning is now removed so users aren't told about unsupported Vulkan support when using Xe2 hardware...

Linux 6.11 merged getrandom() in the vDSO Support for very fast yet secure user-space random number generation needs. That work was initially focused on x86_64 but beginning with Linux 6.12 and following on this getrandom() vDSO implementation will see expanded CPU architecture support...

Weston 14.0 was released today as the newest feature release for this reference Wayland compositor...

When it comes to the Rust programming language support within the Linux kernel one of the limitations is that the CPU architecture support isn't as widespread. Currently Rust for Linux supports x86_64, AArch64 (ARM64) little-endian, LoongArch, and RISC-V. While those cover the main targets, POWER is notably missing and many other niche CPU architectures supported by the Linux kernel especially for aging platforms. Patches posted today to the Linux kernel mailing list would extend the Rust support to MIPS...

Google announced today that the Android 15 source code has been released to the Android Open-Source Project (AOSP)...

While there are more than 74k packages available within Debian's package management system for x86_64 systems, not all of the packages are well maintained and a portion of them haven't seen any maintenance/updates in ages. Debian developers have recently begun discussing how to begin removing more of those long unmaintained packages from the archive...

Now that Linux 6.12 will enable Intel Battlemage and Lunar Lake graphics by default for the out-of-the-box kernel graphics driver support, the user-space Intel Mesa drivers with Iris Gallium3D (OpenGL) and ANV Vulkan are moving ahead to enable their support out-of-the-box too. This has been merged for Mesa 24.3-devel to have Battlemage discrete GPUs enjoying OpenGL and Vulkan support while it's also marked for back-porting to the Mesa 24.2 stable series...

While two years ago Google notably axed support for JPEG-XL within the Chrome web browser, they remain bullish on WebP and AVIF for imaging needs. This past week they finally announced Google Search is now supporting AVIF images...

Firefox 130 web browser binaries were published today ahead of the official release announcement going out on Tuesday. Firefox 130 isn't too particularly exciting but there are a few changes worth mentioning...

The AMD GCN3 (GFX8) support and in particular the Fiji GPU support is being retired from the GNU Compiler Collection (GCC). The Fiji GPU support in the GCC compiler was already deprecated in part due to the LLVM compiler having already removed Fiji support months ago and the AMD ROCm compute driver having broken GCN3 / Fiji support for years...

One year ago the first Rust-written network PHY driver was merged for the Linux 6.8 kernel. Since then we've continued seeing steady progress on more Rust-written Linux network code. With the upcoming Linux 6.12 merge window another Rust PHY driver is set to be introduced...
