Ampere Computing has provided a 160-core Ampere Altra server with 128GB of RAM to the OpenMandriva project to help in speeding up their AArch64 Linux packaging and development efforts...

AMD engineers today released AOMP 16.0-0 as the newest version of their LLVM/Clang downstream compiler where they stage their latest development patches focused on Radeon GPU OpenMP offloading...

It's been two weeks since the release of LLVM 15.0 and its sub-projects like Clang 15.0 so per their rapid release rhythm, out today is LLVM 15.0.1 with the initial batch of fixes...

Merged today for Mesa 22.3 is support with the RadeonSI Gallium3D driver's Video Core Next (VCN) code to support video encoding with LTR mode...

In addition to Intel having closed out last week by submitting their last batch of feature updates to DRM-Next for kernel graphics driver changes slated for Linux 6.1, AMD engineers also did the same with their likely last major set of AMDGPU driver changes intended for this next kernel cycle...

NVIDIA is working on their own address space isolation (ASI) implementation for the Linux kernel that they hope will make the kernel safer for use within automobiles, robotics, and other areas where NVIDIA Tegra embedded hardware has a growing Linux-powered presence...

Intel has become the first corporate "gold" patron to the Krita Foundation for their development fund to advance this open-source digital painting program...

Along with the last drm-intel-gt-next pull for Linux 6.1, a final drm-intel-next pull request of new feature code was submitted to DRM-Next ahead of the upcoming Linux 6.1 merge window...

Earlier this month I wrote about AMD working on s2idle fixes for some AMD Ryzen 6000 series "Rembrandt" laptops. At the time it was just for select ASUS laptops known to have a bug in the firmware resulting in suspend-to-idle issues while now additional models not only from ASUS but also Lenovo have been uncovered...

Chinese hardware vendor Loongson Technology continues working on the LoongArch code for the Linux kernel for their in-house CPU ISA derived from MIPS64. Now that the initial code has been mainlined since 5.19 and some of the necessary other critical bits of code are getting squared away, recently they have been working on other missing functionality for supporting their initial LoongArch-based Loongson 3A5000 series SoCs...

Adding to the growing examples and early drivers being worked on for the Linux kernel to showcase the possibilities of using the Rust programming language within the kernel, an early port of Intel's e1000 wired networking driver has started...

Linus Torvalds just released Linux 6.0-rc6 and it's artificially tiny due to many of the kernel developers being preoccupied for the week...

Back in 2019 is when Intel first detailed the Data Streaming Accelerator "DSA" and began working on the Linux enablement patches. The Intel DSA is designed to help accelerate streaming and transformation operations for storage, networking, and persistent memory. Finally the DSA is coming to market by way of being found within forthcoming Xeon Scalable "Sapphire Rapids" processors while the DSA 2.0 accelerator is already in the works for future processors...

DDraceNetwork "DDNet" as an open-source cross-platform game building off the DDRace and Teeworlds games recently introduced a Vulkan renderer...

Over the summer Jason Donenfeld of WireGuard fame proposed adding getrandom() to the vDSO for better performance to enjoy by user-space developers. This past week he sent out the latest version of this proposed kernel patch where he's seeing around a ~15x speed-up with this change...

Google engineer Yu Zhao this morning published MGLRU v15, the latest revision to this patch series dealing with improving the Linux kernel's page reclamation code. Multi-Gen LRU "MGLRU" has proven to offer performance benefits and particularly improve the Linux experience when dealing with low-memory situations...

Along with the Linux kernel preparing for its initial Rust integration, Rusticl landing in Mesa this week as the first major Rust usage within Mesa, and Cloudflare announcing an Nginx HTTP proxy replacement written in Rust, some additional Rust adoption news for the week is that the GStreamer project is now ready to ship Rust-written plug-ins as part of their official binary releases...

Proposed a few years ago was Kernel Address Space Isolation (KASI / ASI) for limiting data leaks with the growing number of speculative execution attacks on CPUs. Several organizations have been involved with Address Space Isolation efforts for the Linux kernel including IBM, Oracle, and Google with various approaches. Google engineers earlier this year posted a newer iteration of ASI focused on KVM use for the cloud / VMs. ASI still hasn't made it to the mainline kernel but Google engineers this week at LPC argued that it should be be the path forward for mainline in better dealing with these CPU security vulnerabilities...

Over the past year since launching Intel Alder Lake processors, Intel engineers have made a number of improvements to the Linux kernel for better dealing with the hybrid processor approach mixing P and E cores. While Alder Lake is running great with recent kernels and the P vs. E core selection for tasks on Linux is better than it was at launch, there still are areas for improvement as raised by Intel engineers this week...

Longtime Linux kernel engineer Peter Zijlstra with Intel has sent out his latest "Call Depth Tracking" patches as a mitigiation for Retbleed that aims to be less costly on system performance than the current mitigation approach. With this latest patch series, he indicates he hopes to soon get this code mainlined...
