Amazon's Graviton Has Evolved Into A Formidable CPU Contender: Graviton1 To Graviton4 Benchmarks
Amazon's Graviton Has Evolved Into A Formidable CPU Contender: Graviton1 To Graviton4 Benchmarks
85 Minutes Ago - Processors - 6 Comments

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.

AMD's Unified AI Software Stack Might Be A Boon For Other Vulkan/SPIR-V Hardware Too
AMD's Unified AI Software Stack Might Be A Boon For Other Vulkan/SPIR-V Hardware Too
5 Hours Ago - AMD - Unified AI Software Stack + SPIR-V - 5 Comments

Earlier this month AMD talked more about their Unified AI Software Stack plans for debuting in the coming months to provide a unified software view where AI work can be seamlessly offloaded to Ryzen processors, AMD graphics, or AMD Ryzen AI NPU hardware. Another possible and exciting prospect came to mind when going through the LLVM/Clang 19 changes this week.

ASUS ROG Ally X Begins Seeing Linux Patches
ASUS ROG Ally X Begins Seeing Linux Patches
24 July 08:40 PM EDT - Hardware - ASUS ROG Ally X - 5 Comments

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.

LLVM Clang Switches MMX Intrinsics To Use SSE2 Instead
LLVM Clang Switches MMX Intrinsics To Use SSE2 Instead
24 July 07:52 PM EDT - LLVM - SSE2 In Place Of MMX Usage - 9 Comments

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.

Linux 6.11 Lands Support For getrandom() In The vDSO
Linux 6.11 Lands Support For getrandom() In The vDSO
24 July 02:06 PM EDT - Linux Kernel - getrandom() vDSO - 17 Comments

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.

F2FS, exFAT & Btrfs File-System Changes In Linux 6.11
F2FS, exFAT & Btrfs File-System Changes In Linux 6.11
24 July 08:45 AM EDT - Linux Storage - Linux 6.11 File-Systems - 8 Comments

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.

Linux 6.11 Upstream Now Defaults To A Better SATA Link Power Management Policy
Linux 6.11 Upstream Now Defaults To A Better SATA Link Power Management Policy
24 July 06:58 AM EDT - Hardware - SATA Link Power Management - 3 Comments

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.

Intel's Mesa Driver Upstreaming For Xe2 Support Appears Mostly Done
Intel's Mesa Driver Upstreaming For Xe2 Support Appears Mostly Done
23 July 04:09 PM EDT - Intel - Intel Xe2 OpenGL + Vulkan - 4 Comments

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.

Intel Xe2/Battlemage & AMD RDNA4 Lead The Graphics Driver Changes In Linux 6.11
Intel Xe2/Battlemage & AMD RDNA4 Lead The Graphics Driver Changes In Linux 6.11
23 July 11:33 AM EDT - Hardware - Linux 6.11 Graphics Driver Updates - 5 Comments

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.

The BSDs unfortunately continue to lag behind Linux in their GPU driver support. The latest example of this is OpenBSD only days ago seeing initial support for the Video Acceleration API (VA-API) merged for GPU-accelerated video playback on that BSD platform.

Coming just a day after posting a big set of patches for improving VRR display support under the X.Org Server, Enrico Weigelt today announced the release of the X.Org Testing Ground v0.0.4 software that now supports OpenIndiana / Illumos (OpenSolaris) in addition to its Linux and BSD platform support.

Kalray Updates Patches For Their Linux Kernel Port To The KV3-1 "Coolidge" SoC
Kalray Updates Patches For Their Linux Kernel Port To The KV3-1 "Coolidge" SoC
22 July 06:35 AM EDT - Hardware - KVX Linux Kernel Port - Add A Comment

Way back at the start of 2023, French fabless semiconductor company Kalray posted Linux kernel patches for a "KVX" Linux kernel port to get Linux up and running on their MPPA3-80 "Coolidge" DPU SoC with the KV3-1 CPU architecture. A year and a half later this work still is outside the Linux kernel but finally a third iteration of the KVX Linux kernel port has been posted for review.

XZ Patches For The Linux Kernel Updated, Drops "Jia Tan" As A Maintainer
21 July 03:11 PM EDT - Linux Kernel - XZ For The Linux Kernel - 39 Comments

Back in March were a set of patches to the Linux kernel's XZ embedded compression implementation with the project having switched from public domain to the BSD Zero Clause License along with other changes to update that in-tree code. Since then the notorious XZ backdoor situation was discovered in the upstream XZ project. With those major issues behind, Lasse Collin today sent out an updated set of patches for updating the in-tree XZ code for the Linux kernel.

New Linux Patches Enable The Snapdragon X1 Elite Powered Lenovo ThinkPad T14s Gen 6
20 July 06:34 AM EDT - Hardware - Lenovo ThinkPad T14s Gen 6 - 25 Comments

With Linux 6.11 support for the Lenovo Yoga Slim7x and ASUS Vivobook S15 are upstreamed for some of the first Qualcomm Snapdragon X1 Elite powered laptops. But for follow-on kernel cycles you can expect yet more Snapdragon X1 Elite/Plus powered laptop support to appear with new DeviceTree additions. On Friday, Linaro engineer Konrad Dybcio sent out the patches for enabling the X1 Elite powered Lenovo ThinkPad T14s Gen 6 laptop.
