MIPS Tech is no longer working on their MIPS CPU instruction set architecture but has been taking on RISC-V based designs. Today the company made the bold announcement for their new eVocore P8700 and I8500 multiprocessor IP cores that they offer "Best-In-Class Performance and Scalability."..

Intel is kicking off their inaugural "Intel Vision" event today in Texas by making several prominent hardware and software announcements.

AMD today is launching the "refined" AMD Radeon RX 6000 series graphics card line-up with new 2022 models being the RX 6650 XT, RX 6750 XT, and RX 6950 XT graphics cards.

In the absence of the BUS1 in-kernel IPC mechanism that appears stalled that was started after the failed KDBUS effort, Dbus-Broker has been taking off as the high performance, reliability-enhanced Linux message broker in user-space retaining compatibility with the reference D-Bus implementation...

Last month an AMD engineer began posting Linux kernel patches so the kernel prefers the MWAIT instruction over HALT for lowering the CPU idle exit latency. Preferring MWAIT over HALT has been something Intel CPUs on Linux have preferred going back to the Core 2 days and indeed with modern AMD CPUs there is significant advantages to lowering the exit latency in doing so for the idle code. This morning the latest iteration of the work was posted...

Fedora 36 is releasing this morning as what is yet another release in recent times of being a very robust and bleeding-edge yet stable and reliable Linux distribution. I've already been running Fedora Workstation 36 and Fedora Server 36 snapshots on various systems in my benchmarking lab and this release has proven to be quite solid while adding new features and polish on top of the excellent Fedora 35...

Overnight some notable open-source AMD Radeon graphics driver code was merged into what will be the Mesa 22.2 release next quarter...

Ming Lei of Red Hat has published an early implementation of a IO_uring based user-space block driver for Linux...

Last year Intel open-sourced the ControlFlag project for using machine learning to uncover bugs within code. With today's ControlFlag 1.2 release, C++ is now a fully supported language for this AI-driven project for uncovering bugs within arbitrary code-bases...

At the end of April was the release of System76's Pop!_OS 22.04 based on Ubuntu 22.04 but with a variety of improvements from numerous graphical/desktop enhancements down to other changes like their scheduler work and more. For those currently on Pop!_OS 21.10 and wondering about the performance implications, here are some benchmarks showing the performance difference on the same hardware.

Made public last year by Microsoft was CBL-Mariner 1.0 as its internal Linux distribution used for selective purposes from Azure to WSL. This Microsoft "Common Base Linux" distribution has worked well for their internal needs while continuing to make roughly monthly public updates to its 1.0 branch. Today CBL-Mariner 2.0 marks its first production release...

For those making use of FUSE user-space file-system capabilities, developer Dharmendra Singh has posted a patch to allow for non-extending parallel direct writes. In turn for threaded write scenarios this can mean a huge boost to performance...

Merged today into Mesa 22.2 for Raspberry Pi's "V3DV" Vulkan driver is VK_KHR_pipeline_executable_properties support with this extension being used by the likes of RenderDoc for providing more insightful information when profiling Vulkan games and applications...

While the Apple M1 Linux support is off to a great start and using Asahi Linux is offering good CPU performance and most functionality working to at least some degree, the biggest blocker remaining is getting the Apple M1 3D graphics working. The latest progress on that front is the Mesa code working to begin correctly render glmark2, a basic OpenGL / GLES benchmark...

Radeon ProRender as AMD's physically-based rendering engine has added support for The Khronos Group's ANARI analytical rendering interface for 3D data visualizations...

With Plasma 5.25 now under a soft feature freeze ahead of its official release next month, KDE developers are focusing on bug fixing as well as talking more about all of the changes they managed to land this cycle...

Upcoming AMD Zen 4 processors are bringing improvements to their Instruction-Based Sampling (IBS) capabilities that can be utilized by Linux's wonderful perf utility and subsystem...

Linus Torvalds just released Linux 5.18-rc6 as the latest weekly release candidate ahead of the Linux 5.18 stable release expected later in May...

In addition to the ASpeed AST2600 DisplayPort support sent in as part of this week's drm-misc-next updates intended for Linux 5.19, another prominent addition worthy of its own article is the Rockchip VOP2 display driver being mainlined...

Going along with many recent s2idle (suspend to idle) fixes as well as other fixes/workarounds/improvements like around S0ix, a patch is pending as a fix/workaround to get s2idle behaving correctly -- or rather, more timely -- on more AMD Ryzen powered Lenovo laptops...
