Last August I wrote an article about the open-source AMD GPU kernel driver crossing 5 million lines of code -- including their overzealous header files -- and following the recent Linux 6.11 merge window curiosity got the best of me with how much larger the kernel driver is now that the initial RDNA4 support is merged... Well, it's about to cross 5.8 million lines, or about a 16% increase just over the past year...

Ahead of the Linux 6.11-rc2 kernel due for release later today there is the weekly "x86/urgent" material to merge...

Building off some "request for comments" patches sent out in April, a new set of patches appeared on Friday for the Intel P-State Linux driver for setting the asymmetric CPU capacity on hybrid systems. This is another attempt at helping to improve the Linux kernel scheduler behavior in ensuring optimal task placement between Intel Core processors having a mix of P and E cores. This patch series in particular helps when SMT / Hyper Threading support is disabled or like with upcoming Lunar Lake processors where there is no HT support...

It's been four years now that the Btrfs file-system has been the default for Fedora on the desktop. The Fedora and Btrfs love affair has been going well and is only getting better with more integration enhancements planned and a special interest group (SIG) now getting off the ground for furthering these efforts...

The Redox OS project that is a from scratch open-source operating system written in the Rust programming language now has a working web server, among other improvements achieved during the month of July...

The Linux 6.12 kernel cycle later this year has a change coming that will impact users of the "Schedutil" CPU frequency scaling governor. This change is dropping the "LATENCY_MULTIPLIER" that has been within the kernel code the past two decades to slowdown how frequent the CPU frequency evaluation occurs. In turn the revised logic can allow for that CPUFreq frequency re-evaluation to occur more often...

This work is ongoing and for Ubuntu 24.10 they are exploring another exciting area: leveraging "-O3" compiler optimizations for Ubuntu packages. Available today is an experimental build of the Ubuntu desktop and server ISOs that are compiled for the -O3 optimization level...

As expected, AMD has released ROCm 6.2 as the newest version of their open-source GPU compute stack for Radeon graphics cards and Instinct accelerators. ROCm 6.2 is a big update with several new software components, improving the existing PyTorch and TensorFlow support, and a variety of other enhancements as AMD works to better compete with NVIDIA's CUDA...

While Intel's upcoming Core Ultra Series 2 "Lunar Lake" laptop processors are doing away with Hyper Threading (HT) and instead focusing more on additional E cores. AMD has asserted Simultaneous Multi-Threading (SMT) is still beneficial and supported across both their Zen 5 and Zen 5C cores. For those curious about the SMT performance and power efficiency impact, here are some SMT on/off comparison benchmarks using the Ryzen AI 9 HX 370 "Strix Point" laptop processor.

Like most modern Intel and AMD laptops, the new ASUS Zenbook S 16 models for the AMD Ryzen AI 300 series "Strix Point" support ACPI Platform Profiles for allowing the system platform behavior to be modified depending upon whether you are seeking maximum performance, balanced (default), or power savings/efficiency. With the Ryzen AI 9 365 and Ryzen AI 9 HX 370 testing I have been doing thus far it's been on the default balanced mode (along with other laptops being compared) while in this article is a look at the Ryzen AI 9 HX 370 performance impact on the ASUS Zenbook S 16 UM5606WA when trying the other platform profile options.

Microsoft is today promoting the v3.0 release of Azure Linux to stable / general availability status for this Linux distribution formerly known as CBL-Mariner...

One of the many exciting features merged for Linux 6.11 is getrandom() in the vDSO for very fast yet secure random number generation. Now that the kernel bits have landed, it's on to making use of it in the GNU C Library and other libc implementations...

There's been no shortage of cheap, ARM-based handheld game consoles coming to market. Given Linux on Arm tending to work better than Windows and in keeping vendor costs to a minimum, they've tended to be running Linux or Android with various open-source games/emulators. Many of the vendors have kept their Linux support downstream while with time more of these gaming handheld consoles are seeing mainline Linux support. Yet another one being worked on for mainline Linux kernel support is the GameForce Ace...

Merged on Sunday prior to tagging the first release candidate of Linux 6.11 were some last minute updates to Turbostat, the tool that lives within the kernel source tree and used for reporting CPU frequency and idle statistics along with other useful metrics. With Linux 6.11, Turbostat is gaining some new abilities...

While the Linux 6.11 merge window ended just days ago, Intel engineers are already beginning to submit kernel graphics driver changes to the DRM-Next branch of material they want to get in for the Linux 6.12 cycle that will end out 2024. Notable is they are trying to wrap up the Xe2 graphics support for Lunar Lake and Battlemage discrete graphics so that the support can be exposed by default...

Last year the oneAPI Construction Kit was introduced by Intel-owned Codeplay Software for bringing SYCL to new hardware even for hardware outside of Intel's offerings. One of the early targets of this oneAPI Construction Kit support was for RISC-V processors and now with today's release of oneAPI Construction Kit 4.0 there is finally RISC-V host CPU support...

After seeing how the AMD Ryzen AI 9 HX 370 and AMD Ryzen AI 9 365 Zen 5 Strix Point performance is under Linux against a range of other Intel/AMD laptops, the next obvious question is... how does this compare to Windows? In this article is an initial look at the Windows 11 versus Ubuntu 24.04 LTS Linux performance for the same AMD Ryzen AI 9 365 SoC within an ASUS Zenbook S16 and running the same benchmarks in looking at the out-of-the-box performance difference.

Since last year there's been support available in the MSM DRM kernel driver for Qualcomm's Adreno 700 series graphics processors.

That initial open-source drop took place last year as OpenMoonRay and since then it has continued to be improved as an open-source project...

As noted in yesterday's launch-day AMD Ryzen AI 9 HX 370 review with 100+ benchmarks, I've also been testing an AMD Ryzen AI 9 365 Zen 5 laptop too. Here are those initial benchmarks of the AMD Ryzen AI 9 365 as the 10-core / 20-thread laptop Zen 5 SoC. Like with the HX 370 testing, the Ryzen AI 9 365 continues to reinforce the great power efficiency uplift of Zen 5 as one of the most exciting advancements. In fact, for many benchmarks the Ryzen AI 9 365 was delivering even greater performance per Watt than the Ryzen AI 9 HX 370.

It was just two months ago that Oded Gabbay, the longtime maintainer of the Habana Labs kernel accelerator driver for Linux, announced he was stepping down from his software role and leaving Intel. Oded Gabbay was also a maintainer of the new Intel Xe kernel graphics driver. That was a surprising move with Oded Gabbay having been at Intel / Habana Labs for 7+ years and oversaw the creation of the Linux kernel's "accel" accelerator subsystem and more while prior to that having been at Red Hat and AMD. Ofir Bitton was named the Habana Labs driver maintainer following that but now he announced he too is leaving Intel...
