Ampere Computing is mainlining a Linux kernel driver for accessing the sensors of their SMpro co-processor found with their current line of Ampere Altra server processors...
Work carried out by Google engineers and others around the Linux kernel's read-copy update (RCU) synchronization mechanism to make it "lazier" is helping with 5~10% power-savings for idle or lightly-loaded systems. This "Lazy RCU" work is likely to be merged for the Linux 6.2 kernel merge window in December...
Last week Intel began shipping their 13th Gen Core "Raptor Lake" processors. As noted in that launch-day article last week, unfortunately I wasn't able to deliver my usual Linux performance review in time due to hitting some DDR5 issues with my test platform, but those have now been resolved with a new Z790 motherboard. So as the first of my Raptor Lake Linux benchmarks, here is a look at how the top-end Core i9 13900K performs against the AMD Ryzen 7000 series on Ubuntu Linux along with the older Intel/AMD processors.
In recent months there has been a lot of RADV ray-tracing optimizations and improvements for maturing the ray-tracing support by this open-source Radeon Vulkan driver within Mesa. The RADV ray-tracing performance is about to take another step forward with a pending merge request providing a PLOC BVH builder that can improve the Quake II RTX performance by around 33%...
With the recent Linux 6.1 merge window there sadly weren't any Nouveau Direct Rendering Manager (DRM) driver improvements for getting the RTX 30 "Ampere" OpenGL support working yet with the mainline kernel even with RTX 40 series having launched. Needless to say, there also wasn't any progress on the re-clocking front for getting the GTX 900 series and later running in a performant manner on this open-source driver. But the Nouveau developers at Red Hat haven't simply been idling but rather have been working on the NVIDIA GPU System Processor (GSP) support for improving the RTX 20 "Turing" support and newer...
An updated version of the Rust "gccrs" front-end for the GNU Compiler Collection (GCC) was sent out today for review. The GCC Rust "v3" patches address developer comments raised during earlier review as they try to get this new Rust programming language support merged in time for GCC 13...

After the idea has been discussed for about a year, Mesa 22.3 has landed a new performance option called "block_on_depleted_buffers" to wait on buffers at the end of a swap to reduce latency -- a possible one frame advantage...
While various Linux kernel components are increasingly making use of the Zstandard compression algorithm, the Zstd code in the kernel has tended to trail behind upstream. Fortunately, a push is underway to get Zstd 1.5.2 in the Linux 6.2 kernel cycle that kicks off at year's end...
Memtest86+ v6.0 has been released for this open-source system memory (RAM) testing utility. Memtest86+ v6.0 is the first major release of this program in nearly a decade and comes as a complete rewrite to better deal with modern hardware...
sdl12-compat is the library implementation allowing old SDL 1.2 games/software to work atop SDL2. This sdl12-compat can allow for Wayland support if there is no other direct X11 usage by the software itself, native support for PipeWire, improved input controls, and the many other enhancements enjoyed with the much more modern SDL2 library. Released yesterday was sdl12-compat 1.2.60 as the newest stable release for this conversion/support library for vintage software...

AMD today published AOMP 16.0-1 as their newest LLVM/Clang downstream focused on providing the latest Radeon OpenMP GPU offloading support. Notable with this AOMP build is providing initial support for GFX1100 - GFX1103 GPUs. The GFX11 IP block is coming with the soon-to-launch RDNA3 graphics cards and with this AOMP support gives us hope AMD will be providing punctual ROCm support for these next-generation graphics cards...
Last week AMD reaffirmed their 3 November announcement for RDNA3 graphics while today the company announced that one week later on 10 November they will be unveiling their next-gen server processors...
Sony recently announced the DualSense Edge wireless controller for the PlayStation 5 as an "ultra-customizable controller".

Queued up in FUSE's "for-next" kernel branch is a patch worked on in recent months for allowing non-extending parallel direct writes to the same file...
There has long been a debate over an "accelerator" subsystem for the Linux kernel given the increasing number of AI/accelerator devices coming to market. Currently there are accelerator drivers living within the catch-all "char/misc" area of the kernel while some driver efforts have been focused on Direct Rendering Manager (DRM) subsystem integration given the commonality with GPUs and some of the core infrastructure and APIs being relevant for both GPUs and these dedicated accelerator ASICs. There finally seems to be some agreement over the future of the accelerator subsystem and some initial patches were mailed out this weekend...
A new Linux driver introduced by Intel earlier this year was the In-Field Scan for making use of new silicon failure testing functionality with upcoming Intel server CPUs. The IFS driver and associated hardware capability is for detecting potential problems not caught by parity or ECC checks on systems in production. In-Field Scan was merged in Linux 5.19 but then shortly thereafter the driver was marked "broken" due to some driver design issues coming to light. New patches for IFS have been posted to improve the driver's design and remove that "broken" tag...
After being worked on the past year, Mesa 22.3 has landed support for Wayland's DMA-BUF Feedback extension for use by the Mesa Vulkan drivers with the Vulkan windowing system integration (WSI) code...

While Intel with the rest of the tech industry continue investing immense resources in areas around AI and talking it up, one of the efforts that has been slow to materialize on the Linux side has been for enabling their Gaussian and Neural Accelerator (GNA) with the mainline Linux kernel. This week the latest Intel GNA driver patches were posted for this neural co-processor...

Linux's universal TUN driver that provides packet reception and transmission for user-space programs may soon see a 1000x speed-up with a proposed patch sent out today for this network driver...
Last Thursday AMD finally sent out the basic enablement patch for AMD Zen 4 "znver4" with the GCC compiler. Once again it was tardy with Ryzen 7000 series processors already shipping and sadly the cost tables (tuning) is still catering to Zen 3 rather than updated for Zen 4. While as of today this -march=znver4 support has been merged into GCC 13...
Windows users are increasingly making use of Mesa with Microsoft investing in supporting a number of different open, industry standard APIs and then layering them atop the underlying Direct3D 12 driver for the likes of WSL2 usage. OpenGL, OpenCL, Vulkan, and VA-API video acceleration have been the primary targets for Microsoft engineers working on Mesa with the Windows Subsystem for Linux in mind while also posing other possible use-cases where the host may lack native drivers for those APIs. For bettering Mesa on Windows, Microsoft has now added support for compiling against the DirectX 12 Agility SDK...
Thanks to a Google engineer in communication with Microsoft engineers, the "hid-microsoft" upstream Linux driver is seeing work to support the rumble mode on newer Xbox controllers...

If as an Ubuntu Linux user you have been held off on purchasing one of the new Arc Graphics discrete graphics cards due to the prospects of having to upgrade your own kernel, Mesa, and linux-firmware packages, Intel has a solution for Ubuntu 22.04 LTS users in the form of a packaged driver...
Earlier this year Coreboot and the Dasharo downstream were ported to the MSI PRO Z690-A DDR4 motherboard. This was very exciting in that a current-generation Intel desktop motherboard could run Coreboot and readily available through various Internet retailers. But many inquired about whether the MSI PRO Z690-A DDR5 variant would see similar support and now that too is being worked on...
