While most Linux distributions are running on systemd as the init/service manager, SysVinit is continuing to be maintained. SysVinit 3.10 was released today with one new feature and some fixes. Coincidentally the new feature of SysVinit 3.10 is improving compatibility with systemd's machinectl command...

Immediately prior to the Linux 6.11-rc1 kernel being released yesterday, a set of Compute Express Link (CXL) patches were merged for the Linux kernel. There is some more CXL feature work this cycle but also notable is a documentation update as it now provides a concise look at the current state of CXL support on Linux...

As I noted in yesterday's AMD Ryzen AI 9 HX 370 review and in particular the new RDNA3.5-based Radeon 890M graphics, I used updated DMCUB firmware with the open-source Linux graphics driver stack to workaround some screen freezes and kernel errors initially experience while using the Linux 6.10 kernel. That updated DMCUB firmware is now public within the upstream linux-firmware.git repository for those that may be picking up a new AMD Ryzen AI laptop with RDNA3.5 graphics in the coming days...

The Linux 6.11 merge window is over with the Linux 6.11-rc1 release now out the door...

While Linus Torvalds stated in mid-June that he intended to merge sched_ext for Linux 6.11 as the exciting extensible scheduler code, it didn't end up happening... The Linux 6.11-rc1 kernel was just released to close the Linux 6.11 merge window and the sched_ext code wasn't pulled...

With the AMD Zen 5 generation, the timing is interesting where it's not the desktop processors launching first but happens to be in the form of AMD Ryzen AI 300 series laptops. With the last minute delay of the Ryzen 900 series by 1~2 weeks, the embargo lift for the Ryzen AI 300 series is timed for this Sunday morning where I can now present the first AMD Zen 5 Linux benchmark results. And with being the first Zen 5 chip in my lab, I have been pushing it hard... Here is an extensive look at the ASUS Zenbook S 16 I received with the Ryzen AI 9 HX 370 current flagship SoC compared to a variety of other AMD and Intel laptop models. The focus was on both the raw performance and the package performance-per-Watt for the overall power efficiency of this Zen 5 SoC. And with it being the first Zen 5 hardware in the lab, I didn't limit the selection to just conventional laptop workloads but also explored the performance characteristics for various other workloads of interest to diverse Linux users and for an idea of the HX 370 potential or similar Zen 5 chips appearing in thin client / edge / IoT type devices. This initial taste of AMD Zen 5 has me extremely excited about the performance potential of the upcoming Ryzen 9000 series and EPYC Turin processors.

While the upcoming AMD Ryzen 9000 series desktop processors continue to make use of RDNA2 graphics, with the Ryzen AI 300 series shipping today in notebooks there are RDNA3.5 graphics being introduced alongside the Zen 5 CPU cores and upgraded Ryzen AI XDNA2 NPU. While just an evolution of RDNA3, the initial benchmarks of RDNA3.5 graphics with the Ryzen AI 9 HX 370 are looking rather promising for both the raw graphics performance as well as the power efficiency. The Radeon 890M RDNA3.5 graphics are working on Linux when using a new enough software stack.

Merged back in 2021 for Linux 5.13 was Landlock as a means of unprivileged application sandboxing.

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 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...
