Linux Patch Queued To Report Outdated Intel CPU Microcode As A Vulnerability

Last year a patch was raised for the Linux kernel that would report outdated CPU microcode versions as a security vulnerability.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and addressing other functional issues, the Linux kernel would begin warning users when recognizing that outdated CPU microcode is deployed for a given processor.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...

AMD ROCm 6.4 Adds SPIR-V Linking Support To HIP

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...

GCC Patch Revived For -mtune=generic Showing Nice Benefits On Intel & AMD CPUs

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...

Ubuntu 25.04 vs. Windows 11 CPU Performance For The AMD Ryzen AI 7 PRO 360

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 Posts Newest Code For Cache Aware Scheduling On Linux

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...

FamFS Ported To FUSE For Fabric-Attached Memory File-System

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...

NVIDIA Engineer Posts New NOVA Driver Patches - Still Far From Doing Anything Useful

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...

HFS/HFS+ File-System Driver Support For Linux May End Up Being Maintained

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...

FFmpeg AV1 Vulkan Encoder Patch Posted

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...

Google Engineers Exploring Distributed ThinLTO Builds Of The Linux Kernel

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...

Slightly Faster AES-XTS Performance For AVX-512 CPUs Expected With Linux 6.16

In recent kernel releases there have been performance enhancements to the AES implementations and other cryptographic subsystem code for speeding up the performance on modern Intel and AMD processors. With Linux 6.16 there will be at least some additional small gains to find with Intel and AMD processors bearing AVX-512 when employing AES-XTS...

Initial Linux Gaming/Graphics Performance For The NVIDIA GeForce RTX 5060 Ti

Earlier this week the NVIDIA GeForce RTX 5060 Ti launched and there were launch-day Linux CUDA/OpenCL compute benchmarks on Phoronix. But for the Linux gaming performance tests we were waiting on a new supported driver release, which happened to be on launch day with the NVIDIA 575.51.02 Linux beta. Now that the gaming-ready Linux driver is available for the GeForce RTX 5060 series, here are some initial benchmarks of the PNY GeForce RTX 5060 Ti 16GB up against other NVIDIA GeForce and AMD Radeon graphics cards using the newly-released Ubuntu 25.04.

LVFS/Fwupd Is Hoping To Encourage More Hardware Vendors To Provide Financial Backing

The Linux Vendor Firmware Service (LVFS) with the Fwupd client makes it wonderfully easy to enjoy seamless system UEFI and device/peripheral firmware updates under Linux. LVFS is backed by a growing number of major OEMs/ODMs and serves up millions of firmware files. But they are in need of more financial resources from the biggest hardware vendors...

Open-Source RADV Driver Begins Working To Improve AMD RDNA4 Ray-Tracing Performance

While the Radeon RX 9070 series as the first of the AMD RDNA4 graphics cards do perform well on Linux, the one area the performance has been less enticing remains with Vulkan ray-tracing while using the Mesa RADV driver. For example, AMDVLK vs. RADV on the RX 9070 series shows the Mesa driver struggling with ray-tracing compared to the official AMD driver. But the good news is there's a concerted effort now to improve the AMD RDNA4 ray-tracing performance with RADV...

Framework 13 With AMD Ryzen AI 300 Series "Strix Point" Makes For A Great Linux Laptop

Today the review embargo lifts on the Framework 13 with AMD Ryzen AI 300 "Strix Point" SoCs: wow, what an upgrade! I've spent the past week testing out the Framework 13 with the AMD Ryzen AI 9 HX 370 and it's been terrific. Framework 13's modularity continues to pay off and allows easily upgrading to the new Strix Point bearing motherboard with AMD Zen 5 CPU cores and the Radeon 890M (RDNA 3.5) integrated graphics. If you are on a fresh Linux distribution the support is in great shape and paired with great performance for delivering a great 2025 Linux laptop option.

Intel Continues Exploring Energy Aware Scheduling For Hybrid CPUs Without SMT

While Intel's Core Ultra 200V "Lunar Lake" SoCs with on-package memory has been reported to be a one-off design, besides the integrated memory it was also notable for being a hybrid core design while lacking Hyper Threading (HT / SMT) support. The notion of hybrid P/E core CPUs without SMT looks like it will continue with Intel software engineers still exploring Energy Aware Scheduling (EAS) around such layouts...
