Last week I published some initial benchmarks of the Amazon/AWS Graviton4 processors now available within the EC2 cloud using the new "R8g" instances. That initial comparison was a 64 vCPU comparison of Graviton4 against AMD EPYC and Intel Xeon 64 vCPU AWS instances. In today's article is a look at the 96-core Graviton4 bare metal performance using the "r8g.metal-24xl" AWS instance type. The Graviton4 r8g.metal-24xl performance was then compared in today's article against various bare metal AMD EPYC, Ampere Altra Max, and Intel Xeon processors in the lab at Phoronix.

With the maturity of the EXT4 file-system it's not too often seeing any huge feature additions for this commonly used Linux file-system but there's still the occasional wild performance optimization to uncover... With Linux 6.11 the EXT4 file-system can see upwards of a 20% performance boost in some scenarios...

Toward the end of 2022 a GCC AArch64 compiler change was quietly made by Arm that allows "-march=native" to be handled on 64-bit ARM by treating it as the equivalent "-mcpu=native" option. The change happened to fly under my radar at that time and didn't draw much attention at large while now it's finally being officially documented in hopes of similar behavior being adopted by other compilers for AArch64...

The ROCm 6.1 series is the latest stable version currently of AMD's open-source GPU compute stack with an increasing large focus on AI.

Microsoft today published a new version of their Windows Subsystem for Linux (WSL) in pre-release form...

While Rust is viewed as a memory safe and robust programming language, there is the "unsafe" keyword within Rust that can be used for unsafe code that grants "unsafe superpowers" for the language. As dealing with Rust at low-levels as the Linux kernel can lead to needing to use "unsafe" Rust at times, a documentation standard has been proposed for dealing with such code inside the kernel...

It's been a wild two years since NVIDIA began publishing an open-source Linux GPU kernel driver for Turing GPUs and newer. With the latest NVIDIA 555 Linux driver series that open-source kernel driver support is in great shape and NVIDIA today is out with a lengthy blog post promoting it...

Last week with delivering a number of AMD vs. NVIDIA Vulkan ray-tracing benchmarks under Linux with the current drivers and using the new "Breaking Limit" benchmark, the question was raised how well does AMD's official "AMDVLK" Vulkan driver handle ray-tracing these days compared to the more popular Mesa RADV Vulkan driver used commonly by Linux gamers and as the default driver on most Linux distributions. Here is a fresh look at the RADV versus AMDVLK Vulkan performance on Linux with a focus on ray-tracing performance.

Installing the NVIDIA proprietary graphics driver stack on Fedora currently doesn't jive with UEFI Secure Boot systems and can lead to the OS being unbootable. As such, the NVIDIA driver option was previously removed from GNOME Software. But as the NVIDIA driver is still widely sought after on Fedora by Linux gamers and those wanting to run CUDA/AI workloads especially, Fedora 41 is now cleared to roll-out NVIDIA driver support with UEFI Secure Boot integration...

While many have been excited around the prospects of laptops powered by the Qualcomm Snapdragon X Elite SoC, the Linux support so far still leaves a lot to be desired... The initial Snapdragon X Elite laptops aren't utilizing ACPI standards and the bring-up under Linux has been slow, but patches have begun appearing for some models. But even with patches, the Adreno GPU remains a big obstacle still being tackled along with other features like web camera, USB4, Bluetooth, etc. With a new kernel patch, the GPU for the Snapdragon X Elite (X1E80100) is being disabled by default...
