A final batch of drm-intel-next feature patches were submitted on Friday to complement the drm-intel-gt-next patches. Most exciting with this last minute PR for Linux 6.2 is the DG2/Alchemist discrete GPU support no longer being treated as experimental...
In early 2020 the software engineers at Micron announced an open-source storage engine designed for SSDs and persistent memory. The storage engine prided itself on being a speedy key-value store database and there was also a MongoDB-based implementation. Last year HSE 2.0 debuted and the updated storage engine no longer relied on modifications to the Linux kernel and now strictly a user-space based solution. This week the Micron engineers are celebrating HSE 3.0 as their latest work on this open-source storage engine...
Being queued up via the x86 platform driver's "for-next" branch ahead of the Linux 6.2 cycle is the dell-wmi-ddv driver, which is for exposing the WMI interface of the Dell Data Vault (DDV)...
Back during the summer was news that Ikey Doherty was going to work full-time on Serpent OS, a new Linux distribution he started. Ikey Doherty as a reminder previously created the Solus Linux distribution, worked for Intel on Clear Linux, and has other software accomplishments to his name. It's been a quiet few months for Serpent OS but it turns out they've been busy establishing their build infrastructure and tooling...
Last week when launching the AMD EPYC 9004 "Genoa" processors, AMD released AOCC 4.0 as the newest version of their optimizing C/C++ compiler that now supports their Zen 4 micro-architecture. Last week I ran some initial AOCC 4.0 benchmarks and this LLVM/Clang downstream was looking rather favorable in relation to upstream LLVM/Clang, while since then I've been able to conduct more thorough benchmarks across a wide variety of C/C++ open-source workloads. Here is that more extensive round of AOCC 4.0 benchmarking against the open-source LLVM/Clang and AOCC compilers.
Amazon Web Services (AWS) announced this week that their Krakatoa product-grade, volumetric renderer has been made open-source. AWS also open-sourced their XMesh software to optimize animated 3D geometry asset files...
Mesa VirGL with the virglrenderer library has allowed for virtual 3D GPU support within QEMU virtual machines. This Gallium3D-leveraging code has allowed for OpenGL and other functionality to work within VMs while leveraging the host's GPU. The latest notable addition is adding VirGL video encoding support with H.264 and H.265 initially being supported for accelerated support in VMs...
This summer AMD announced the Radeon Raytracing Analyzer "RRA" as part of their developer software suite for helping to profile ray-tracing performance/issues on Windows and Linux with both Direct3D 12 and the Vulkan API. Initially the RRA 1.0 release was binary-only but now AMD has made good on their "GPUOpen" approach and made it open-source...

For those wondering about the out-of-the-box performance of different modern Linux distributions when running the new Intel Raptor Lake processors, here are six different distributions running on the current flagship Core i9 13900K processor. Tested this round was CentOS Stream 9, Clear Linux, Debian Bookworm (Testing), EndeavourOS, Fedora Workstation 37, and Ubuntu 22.10.
In addition to the very successful FEX-Emu emulator for enjoying Linux x86/x86_64 games on AArch64 and other x86/x86_64 software on Arm there is also the Box86 and Box64 projects with similar goals. Out today is Box64 v0.2 and Box86 v0.2.8 for running Linux binaries on other architectures...
OpenSUSE has officially released openSUSE Leap Micro 5.3 as the newest version of their OS built atop SUSE Linux Enterprise 15 SP4 and SLE Micro 5.3 for providing a lightweight, modern OS that is auto-updating, immutable, and provides other distinct features over Tumbleweed or Leap...
Currently when hot-plugging a new GPU to a running X.Org Server, the generic xf86-video-modesetting DDX driver ends up being utilized. However, a new "HotplugDriver" xorg.conf option has been introduced by AMD to allow users to specify their desired DDX driver. In turn this makes it possible for those hot-plugging hardware like AMD Radeon GPUs such as within eGPU enclosures to specify using the xf86-video-amdgpu driver instead...
Mesa's AGX "Asahi" Gallium3D driver for providing OpenGL / GLES support on Apple M1/M2 SoCs has begun making some early preparatory changes for eventually supporting the in-development DRM/KMS kernel driver. The kernel driver is still a work-in-progress and not close to being merged yet and the user-space API not yet set in stone, but some early changes in better preparing the Mesa driver for actually running on the Apple Silicon hardware under Linux have been merged...

Back in March AMD began sending out patches for PerfMonV2 support with Zen 4 CPUs. This updated AMD Performance Monitoring "V2" code has premiered now with AMD Ryzen 7000 series and AMD EPYC 9004 series processors and the host-side PerfMonV2 code was merged in Linux 5.19. But support for PerfMonV2 within KVM guests has been lacking while now an updated patch series is working to address the functionality there...
Adding to the growing list of changes expected to be sent in during the Linux 6.2 merge window next month is HID-BPF. This is the Red Hat led effort around using eBPF within the HID subsystem for input devices...
Last week for the AMD EPYC 4th Gen "Genoa" launch day I published initial AMD EPYC 9554 and EPYC 9654 Linux benchmarks as part of my review. Those 64-core and 96-core Zen 4 processors performed phenomenally with Genoa having AVX-512, twelve channels of DDR5-4800 system memory support, higher TDP allowance, and other improvements over prior Milan(X) server processors. The other SKU that AMD sent over for review is the EPYC 9374F as their new 32-core high frequency part. For less than $5k, the EPYC 9374F is a high frequency Zen 4 32-core part with a 320 Watt TDP. Today's benchmarks are looking at the EPYC 9374F against the EPYC 9554/9654 and various other AMD EPYC and Intel Xeon Scalable processors under Linux.

Since last year when building the Linux kernel using LLVM's Clang compiler it's been possible to enable link-time optimizations (LTO) for the kernel build. Building the Linux kernel with GCC has lacked LTO support while a patch series posted today is the latest attempt to make that happen...
Leading AArch64 server processor vendor Ampere Computing announced this summer AmpereOne as the branding for their next-generation AArch64 "cloud native" server processor design succeeding their current Ampere Altra / Ampere Altra Max processors based on Neoverse-N1. While the AmpereOne processors have yet to be formally launched, with the new AArch64 core being an original design, Ampere Computing has already been submitting support patches to the open-source compilers. The latest twist in this enablement is now acknowledging a new "Ampere-1A" variant...
