Last year a patch was raised for the Linux kernel that would report outdated CPU microcode versions as a security vulnerability. With Intel routinely issuing new CPU microcode updates for security vulnerabilities and addressing other functional issues, the Linux kernel would begin warning users when recognizing that outdated CPU microcode is deployed for a given processor. That patch has now been queued into a tip/tip.git branch and thus looking like it will be submitted for the upcoming Linux 6.16 kernel cycle.

With the recently released AMD ROCm 6.4 release for this open-source GPU compute stack for Radeon and Instinct hardware there are yet more indications around AMD's growing software ecosystem expansion. With ROCm 6.4 are additions to the HIP API for allowing linking of SPIR-V code objects, which is the intermediate representation used by Vulkan as well as with OpenCL and other Khronos APIs.

A 2021 era patch for the GNU Compiler Collection (GCC) has been revived and discussed in recent days around simplifying the memcpy and memset inlining strategies when compiling code with the "-mtune=generic" option. The patch takes the approach during that generic tuning to try to avoid branches. In doing so, some nice performance benefits are observed in some benchmarks.

Earlier this month was a look at the AMD RDNA 3.5 graphics between Windows 11 and Ubuntu 25.04 using a Ryzen AI 7 PRO 360 "Strix Point" SoC within a Lenovo ThinkPad T14s Gen 6. That was an interesting benchmark battle and providing a fresh look at the open-source AMD Linux graphics driver stack relative to Radeon Software on Windows. For those curious about the current Zen 5(C) performance, today's article are all of the CPU benchmarks for the AMD Ryzen AI 7 PRO 360 performance under the newly-released Ubuntu 25.04 and Windows 11 as pre-loaded by Lenovo.

Intel engineers have recently been working on the notion of cache-aware scheduling / load balancing for benefiting the likes of Intel and AMD processors sporting multiple caches. Posted today was the newest iteration of these patches that are still seeking to get more feedback and testing around this potential useful addition to the Linux kernel.

One year ago we covered Micron working on FamFS as a new file-system for fabric-attached memory with an emphasis on Compute Express Link (CXL) devices. That started off as a conventional kernel driver while now the newest patches posted this weekend are morphing it into a user-space driver via FUSE.

Merged last year in Linux 6.11 was getrandom() support in the vDSO for x86/x86_64 and then in Linux 6.12 was extended to LoongArch and ARM64. With the upcoming Linux 6.16 cycle, this support for faster while still secure RNG for user-space is set to come to RISC-V.

After missing its bi-weekly development release regiment this past Friday, Wine 10.6 was tagged on Sunday as the newest routine update to this open-source software that enables Windows applications and games to run on Linux and other platforms.

Easter doesn't get in the way of Linus Torvalds' weekly kernel release regiment: Linux 6.15-rc3 is now available for testing the latest kernel fixes ahead of the stable Linux 6.15 kernel release coming around the end of May.

Merged for the Linux 6.15 kernel were the very early boilerplate code around the NOVA driver as a new, open-source and Rust-written NVIDIA Linux kernel graphics/display driver. This successor to the Nouveau kernel driver is going to leverage the NVIDIA GPU System Processor (GSP) to make it easier to develop and maintain this open-source driver. But depending upon the GSP also means the NOVA driver will only work with RTX 20 class GPUs and newer. This driver is going to be built up gradually within the mainline Linux kernel and coming out this Easter were a new set of 16 patches for further laying the NOVA groundwork.

Sway 1.11-rc1 is out today as a test release ahead of this next Wayland compositor feature release. Sway 1.11 is bringing a number of new features for this i3-inspired Wayland compositor while also building off the new features laid out in the recent wlroots 0.19-rc1 library.

The FreeType library for rendering text onto bitmaps that is widely used by a variety of applications has landed a set of three patches today providing an important performance improvement to address a significant inefficiency within the existing FreeType codebase.

Greg Kroah-Hartman has released a few new Linux kernel stable point releases today for Easter and also capping off the Linux 6.13 kernel cycle in the process.

The long-in-development OpenVPN DCO kernel driver for providing data channel offloading (DCO) to yield faster OpenVPN performance looks like it's now in a state for upstreaming with the Linux 6.16 kernel.

Just a few days ago there was talk of potentially removing the Apple HFS and HFS+ file-system drivers from the Linux kernel considering they had been orphaned for a decade and beginning to cause a maintenance burden. After briefly being marked for deprecation, it now looks like the drivers may be maintained with new maintainers alleging to step-up to the role.

The Intel Integrated Sensor Hub "ISH" allows for offloading sensor polling and other tasks to a low-power co-processor to help reduce overall system power consumption for extending battery life with tablets, embedded devices, and 2-in1 laptops.

While the FFmpeg multimedia library merged Vulkan Video encode support last year, it was initially limited to H.264 and H.265 formats. With a new patch posted for review this week, AV1 encode support using the Vulkan Video API is now underway.

GNU/Hurd has long struggled with hardware support and is still working on its x86_64 support while having a host of various hardware limitations but it also appears they are eager to explore Hurd on RISC-V platforms.

Engineers from Google are proposing that distributed ThinLTO build support be introduced for LLVM/Clang when compiling the Linux kernel. The distributed ThinLTO mode for link-time optimizations can lead to quicker build times than the current in-process ThinLTO mode while also being more convenient and work with kernel live-patching solutions.

KDE developers continue to be very busy working toward the Plasma 6.4 desktop release and making other enhancements throughout this open-source desktop.
