Merged one year ago for Linux 6.6 was the EEVDF scheduler as a replacement to the CFS code and designed to provide a better scheduling policy for the kernel and being more robust. With a new set of patches for this "Earliest Eligible Virtual Deadline First" scheduling code, it's nearing the point of officially being completed...

Ahead of the Linux 6.11 merge window set to close tomorrow, Linux engineer Christian Brauner at Microsoft sent in a set of two VFS fixes. One of the fixes is more noteworthy that is for a five year old bug that could cause on-disk corruption, security issues, or a kernel crash...

While most Linux file-systems are rather robust in recovering when the system experiences a power loss, the UBIFS file-system is more prone to problems when a power-cut happens. With patches submitted for the Linux 6.11 merge window, UBIFS is seeing some hardening so it can better cope with the loss of power...

Following Linus Torvalds receiving an Ampere Altra Max workstation from Ampere Computing, he's been dabbling more with ARM64 now that it affords him more AArch64 compute power than his Apple Silicon powered MacBook. Torvalds kicked off the Linux 6.11 merge window by landing some of his own code to further enhance the ARM64 kernel and as we approach the end of the v6.11 merge window this weekend, he's merged some more ARM64 code...

With the recently introduced NVIDIA 555 Linux driver stable series their open-source GPU kernel driver modules are in great shape across consumer and professional graphics products. Over the past two years the support has evolved so much that NVIDIA is now promoting their open-source kernel driver usage and with the NVIDIA 560 Linux driver beta posted this week they are defaulting to using their open-source kernel driver modules in place of the proprietary option -- on the Turing and newer GPUs supported by the open-source code. Here is a fresh look at the impact.

Amazon's Graviton4 server processor that recently went into GA in the AWS cloud is easily the most competitive AArch64 server processor we've seen to date and proving capable of being able to compete with Intel Xeon and AMD EPYC processors across various workloads. Since Graviton4 went GA on AWS earlier this month I've looked at the Graviton4 comparison to other instances at 64 vCPUs and also comparing the Graviton4 96-core metal performance to various Intel, Ampere, and AMD processors. Given the interest in those Graviton4 benchmarks, today's article is another look at Graviton4 looking at the metal performance compared to prior generation Graviton3, Graviton2, and Graviton1 instances for showing just how far Amazon's Graviton processor performance has evolved.

The Qt Group today released Qt Creator 14 as the newest version of this Qt and C++ focused integrated development environment (IDE) for developers...

This weekend the ASUS ROG Ally X began shipping as an upgraded version of the ASUS ROG Ally handheld gaming console that launched last year. The ASUS ROG Ally X is still powered by the AMD Ryzen Z1 Extreme SoC and for the most part similar to the original model but now with 24GB of LPDDR5X-7500 memory up from 16GB of LPDDR5-6400, twice as large battery capacity, 1TB of NVMe storage rather than 512GB, improved input controls, improved cooling, and other refinements. But it still is running Microsoft Windows 11 out-of-the-box...

Following LLVM/Clang recently dropping support for AMD 3DNow! instructions, the open-source compiler stack is now pushing the MMX SIMD instruction set to a backseat. Moving forward the MMX intrinsics will not make use of MMX but rather be mapped to SSE2. This is all fine unless you are wanting to use this modern code compiler on an Intel Pentium MMX / Pentium II / Pentium III or AMD K6 / K7 processor from the late 90's...

While we have been super eager for the AMD Ryzen 9000 series "Zen 5" desktop processor launch that's been set for 31 July, AMD has issued a last minute delay. Instead the processors will launch in two stages in August...

Going back two years has been the effort for adding getrandom() to the vDSO in order to enhance the performance. This work has yielded as much as 15x the performance in showing very fast while being secure user-space RNG needs. A few weeks back Linus Torvalds was unconvinced by adding getrandom() to the vDSO, but after going back through the patches he gave it another go. Today the work has managed to be mainlined for Linux 6.11...

The latest Rust for the Linux kernel work led by Miguel Ojeda is on preparing the Rust kernel code for various CPU security mitigations...

While not as notable as the nice EXT4 performance optimization making it into Linux 6.11 or features like XFS real-time FITRIM and self-healing Bcachefs on read I/O errors, the Bcachefs, F2FS, and Btrfs file-systems saw smaller updates for the Linux 6.11 kernel cycle...

It's not too often that the ATA pull request for a new Linux kernel merge window has much worth mentioning. With Linux 6.11 there is a change to the kernel defaults worth noting over the default SATA link power management policy. In this case most Linux distributions have been setting a better default themselves and is now a case of the upstream kernel defaults catching up...

The latest video acceleration improvements to report on with the open-source AMD Radeon driver front is support in Mesa 24.3-devel for passing HDR metadata in the AV1 encoder...

The upstream Linux 6.11 kernel is making it easier to build a Pacman package of the kernel for use on Arch Linux and other Arch derived distributions relying on Pacman...

Ahead of launch for new discrete/integrated graphics backed by open-source Linux drivers, it can often be difficult to ascertain the level of support pre-launch given the complexity of today's GPUs, we are past the days of long monolithic patch series for new hardware enablement, and also not knowing about what features may be added for the next-generation hardware. But if latest Mesa developer comments hold, it looks like for Intel Xe2 graphics the open-source Vulkan driver at least has "most" of the code now in place...

DRM subsystem lead maintainer David Airlie recently submitted the DRM-Next pull request for merging into Linux 6.11. All of that Direct Rendering Manager (DRM) feature code has landed for the many kernel graphics/display driver updates along with changes to the few AI accelerator "accel" drivers also part of the tree. As usual, the Intel Xe/i915 and AMD AMDGPU/AMDKFD kernel drivers see a bulk of the upstream open-source graphics improvements...
